Goldman Sachs Blue Chip Fund

Goldman Sachs Blue Chip Fund—Summary

Investment Objective

The Goldman Sachs Blue Chip Fund (formerly Goldman Sachs Dynamic U.S. Equity Fund) (the “Fund”) seeks long-term growth of capital.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class A Shares if you invest at least $50,000 in Goldman Sachs Funds. More information about these and other discounts is available from your financial professional and in “Shareholder Guide—Common Questions Applicable to the Purchase of Class A Shares” beginning on page 46 and in Appendix C—Additional Information About Sales Charge Variations, Waivers and Discounts on page 86 of the Prospectus and “Other Information Regarding Maximum Sales Charge, Purchases, Redemptions, Exchanges and Dividends” beginning on page B-106 of the Fund’s Statement of Additional Information (“SAI”).

Expense Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Investor, Class R and/or Class R6 Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Investor, Class R and/or Class R6 Shares at the end of those periods, unless otherwise stated. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same (except that the Example incorporates the fee waiver and expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Assuming complete redemption at end of period

Expense Example - Goldman Sachs Blue Chip Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A Shares	649	1,540	2,439	4,726
Class C Shares	281	1,264	2,341	5,010
Institutional Shares	68	936	1,818	4,094
Investor Shares	80	974	1,882	4,211
Class R Shares	130	1,120	2,115	4,622
Class R6 Shares	67	933	1,814	4,085

Assuming no redemption

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
Goldman Sachs Blue Chip Fund | Class C Shares | USD ($)	181	1,264	2,341	5,010

Portfolio Turnover

The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended August 31, 2017 was 77% of the average value of its portfolio.

Principal Strategy

The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at the time of purchase) (“Net Assets”) in a diversified portfolio of equity investments of “blue chip” companies. Blue chip companies are companies that, in the Investment Adviser’s view, enjoy characteristics that include strong market positions, seasoned management teams, solid financial fundamentals and high-quality reputations. Although blue chip companies generally have large or medium market capitalizations, the Investment Adviser may invest in companies that it believes have good, long-term prospects to become well-known, established or blue chip companies. The Fund may also invest up to 20% of its Net Assets in foreign securities.

The Fund’s portfolio managers combine ideas from the Goldman Sachs Asset Management Growth and Value Teams to provide broad U.S. equity market exposure using securities of “blue chip” companies of any investment style. The Goldman Sachs Asset Management Growth Team uses fundamental research to identify strong business franchises with favorable long-term growth prospects, excellent management and high-quality reputations. Investment criteria include dominant market share, positive free cash flow, enduring competitive advantages and sustainable growth. The process also includes a valuation component. The Goldman Sachs Asset Management Value Team’s philosophy is based on the belief that all successful investing should thoughtfully weigh two important attributes of a stock: price and prospects. The team uses a strong valuation discipline to purchase well-positioned, cash-generating businesses run by shareholder-oriented management teams.

The Fund’s equity investment process involves: (1) using multiple industry-specific valuation metrics to identify real economic value and company potential in stocks, screened by valuation, profitability and business characteristics; (2) conducting in-depth company research and assessing overall business quality; and (3) buying those securities that a sector portfolio manager recommends, taking into account feedback from the rest of the portfolio management team. The Investment Adviser may decide to sell a position for various reasons, including valuation and price considerations, readjustment of the Investment Adviser’s outlook based on subsequent events, the Investment Adviser’s ongoing assessment of the quality and effectiveness of management, if new investment ideas offer the potential for better risk/reward profiles than existing holdings, or for risk management purposes. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions.

The Fund may also, but does not currently intend to, invest in fixed income securities, including government, corporate and bank debt obligations.

The Fund’s benchmark index is the S&P 500^® Index.

Principal Risks of the Fund

Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing.

Foreign Risk.   Foreign securities may be subject to risk of loss because of more or less foreign government regulation, less public information and less economic, political and social stability in the countries in which the Fund invests. The imposition of exchange controls, confiscations, trade restrictions (including tariffs) and other government restrictions by the United States and other governments, or from problems in share registration, settlement or custody, may also result in losses. Foreign risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time.

Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles.

Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s net asset value (“NAV”) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio.

Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.

Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

Performance

The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund’s Class A Shares from year to year; and (b) how the average annual total returns of the Fund’s Class A, Class C, Institutional, Investor, Class R and Class R6 Shares compare to those of a broad-based securities market index. Between May 1, 2015 through October 31, 2017, the Fund had been known as the Goldman Sachs Dynamic U.S. Equity Fund and, since the Fund’s inception through April 30, 2015, the Fund had been known as the Goldman Sachs U.S. Equity Fund, and certain of its principal investment strategies differed. Performance information set forth below prior to October 31, 2017 reflects the performance resulting from the Fund’s former strategies. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus.

The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

TOTAL RETURN CALENDAR YEAR (CLASS A)

The total return for Class A Shares for the 9-month period ended September 30, 2017 was 12.72%.

Best Quarter

The after-tax returns are for Class A Shares only. The after-tax returns for Class C, Institutional, Investor and Class R6 Shares, and returns for Class R Shares (which are offered exclusively to employee benefit plans), will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[1] The Fund’s “Management Fees” have been restated to reflect current fees.

[2] The Investment Adviser has agreed to reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.084% of the Fund’s average daily net assets. Additionally, Goldman Sachs & Co. LLC (“Goldman Sachs”), the Fund’s transfer agent, has agreed to waive a portion of its transfer agency fee (a component of “Other Expenses”) equal to 0.03% as an annual percentage rate of the average daily net assets attributable to Class A, Class C, Investor, and Class R Shares of the Fund. These arrangements will remain in effect through at least December 29, 2018, and prior to such date, the Investment Adviser and Goldman Sachs may not terminate the arrangements without the approval of the Board of Trustees.

[3] After Fee Waiver and Expense Limitation

[1] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares' inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

Currency exchange rates may fluctuate significantly over short periods of time. Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles. Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s net asset value (“NAV”) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio. Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets. Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

Between May 1, 2015 through October 31, 2017, the Fund had been known as the Goldman Sachs Dynamic U.S. Equity Fund and, since the Fund’s inception through April 30, 2015, the Fund had been known as the Goldman Sachs U.S. Equity Fund, and certain of its principal investment strategies differed. Performance information set forth below prior to October 31, 2017 reflects the performance resulting from the Fund’s former strategies. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[2] The Fund’s “Management Fees” have been restated to reflect current fees.

[3] The Investment Adviser has agreed to reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.084% of the Fund’s average daily net assets. Additionally, Goldman Sachs & Co. LLC (“Goldman Sachs”), the Fund’s transfer agent, has agreed to waive a portion of its transfer agency fee (a component of “Other Expenses”) equal to 0.03% as an annual percentage rate of the average daily net assets attributable to Class A, Class C, Investor, and Class R Shares of the Fund. These arrangements will remain in effect through at least December 29, 2018, and prior to such date, the Investment Adviser and Goldman Sachs may not terminate the arrangements without the approval of the Board of Trustees.

[4] After Fee Waiver and Expense Limitation

[5] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares' inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

Expense Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares at the end of those periods, unless otherwise stated. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same (except that the Example incorporates the fee waiver and expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Assuming complete redemption at end of period

Expense Example - Goldman Sachs Capital Growth Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A Shares	660	906	1,172	1,929
Class C Shares	292	609	1,051	2,280
Institutional Shares	77	255	448	1,007
Service Shares	127	411	717	1,584
Investor Shares	91	299	524	1,172
Class R Shares	142	455	791	1,740
Class R6 Shares	76	252	443	995
Class T Shares	363	618	892	1,673

Assuming no redemption

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
Goldman Sachs Capital Growth Fund | Class C Shares | USD ($)	192	609	1,051	2,280

Portfolio Turnover

The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended August 31, 2017 was 48% of the average value of its portfolio.

Principal Strategy

The Fund invests, under normal circumstances, at least 90% of its total assets measured at time of purchase (“Total Assets”) in equity investments. Although the Fund invests primarily in publicly traded U.S. securities, it may invest up to 25% of its Total Assets in foreign securities, including securities of issuers in countries with emerging markets or economies (“emerging countries”) and securities quoted in foreign currencies.

The Fund seeks to achieve its investment objective by investing, under normal circumstances, in approximately 90-130 companies that are considered by the Investment Adviser to be positioned for long-term growth. The Fund’s fundamental equity growth investment process involves evaluating potential investments based on specific characteristics believed to indicate a high-quality business with sustainable growth, including strong business franchises, favorable long-term prospects, and excellent management. The Investment Adviser will also consider valuation of companies when determining whether to buy and/or sell securities. The Investment Adviser may decide to sell a position for various reasons, including when a company’s fundamental outlook deteriorates because of valuation and price considerations, for risk management purposes, or when a company is deemed to be misallocating capital. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions.

The Fund may invest up to 10% of its Total Assets in fixed income securities, such as government, corporate and bank debt obligations.

The Fund's benchmark index is the Russell 1000^® Growth Index.

Principal Risks of the Fund

Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing.

Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles.

Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s net asset value (“NAV”) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio.

Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.

Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

Performance

The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund’s Class A Shares from year to year; and (b) how the average annual total returns of the Fund’s Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and Class T Shares compare to those of a broad-based securities market index. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus.

The bar chart (including "Best Quarter" and "Worst Quarter" information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

The after-tax returns are for Class A Shares only. The after-tax returns for Class C, Institutional, Service, Investor, Class R6 and Class T Shares, and returns for Class R Shares (which are offered exclusively to employee benefit plans), will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[1] The Fund’s “Management Fees” have been restated to reflect current fees.

[2] The "Other Expenses" for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[3] The Investment Adviser has agreed to reduce or limit "Other Expenses" (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, shareholder administration fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% of the Fund's average daily net assets. This arrangement will remain in effect through at least December 29, 2018, and prior to such date the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees.

[4] After Expense Limitation

[1] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares' inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[2] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares’ inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended August 31, 2017 was 48% of the average value of its portfolio.

Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares at the end of those periods, unless otherwise stated. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same (except that the Example incorporates the fee waiver and expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example, No Redemption, By Year, Caption [Text]	rr_ExpenseExampleNoRedemptionByYearCaption	Assuming no redemption
Strategy [Heading]	rr_StrategyHeading	Principal Strategy
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests, under normal circumstances, at least 90% of its total assets measured at time of purchase (“Total Assets”) in equity investments. Although the Fund invests primarily in publicly traded U.S. securities, it may invest up to 25% of its Total Assets in foreign securities, including securities of issuers in countries with emerging markets or economies (“emerging countries”) and securities quoted in foreign currencies. The Fund seeks to achieve its investment objective by investing, under normal circumstances, in approximately 90-130 companies that are considered by the Investment Adviser to be positioned for long-term growth. The Fund’s fundamental equity growth investment process involves evaluating potential investments based on specific characteristics believed to indicate a high-quality business with sustainable growth, including strong business franchises, favorable long-term prospects, and excellent management. The Investment Adviser will also consider valuation of companies when determining whether to buy and/or sell securities. The Investment Adviser may decide to sell a position for various reasons, including when a company’s fundamental outlook deteriorates because of valuation and price considerations, for risk management purposes, or when a company is deemed to be misallocating capital. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions. The Fund may invest up to 10% of its Total Assets in fixed income securities, such as government, corporate and bank debt obligations. The Fund's benchmark index is the Russell 1000® Growth Index.
Risk [Heading]	rr_RiskHeading	Principal Risks of the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing. Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles. Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s net asset value (“NAV”) and liquidity.

[2] The Fund’s “Management Fees” have been restated to reflect current fees.

[3] The "Other Expenses" for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[4] The Investment Adviser has agreed to reduce or limit "Other Expenses" (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, shareholder administration fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% of the Fund's average daily net assets. This arrangement will remain in effect through at least December 29, 2018, and prior to such date the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees.

[6] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares' inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[7] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares’ inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares.

Goldman Sachs Concentrated Growth Fund

Goldman Sachs Concentrated Growth Fund—Summary

Investment Objective

Expense Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Investor, Class R, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Investor, Class R, Class R6 and/or Class T Shares at the end of those periods, unless otherwise stated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the fee waiver and expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Assuming complete redemption at end of period

Expense Example - Goldman Sachs Concentrated Growth Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A Shares	662	948	1,256	2,127
Class C Shares	294	652	1,137	2,473
Institutional Shares	82	303	542	1,228
Investor Shares	93	344	614	1,387
Class R Shares	144	499	879	1,944
Class R6 Shares	81	300	536	1,216
Class T Shares	365	661	979	1,878

Assuming no redemption

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
Goldman Sachs Concentrated Growth Fund | Class C Shares | USD ($)	194	652	1,137	2,473

Portfolio Turnover

The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended August 31, 2017 was 54% of the average value of its portfolio.

Principal Strategy

The Fund invests, under normal circumstances, at least 90% of its total assets measured at time of purchase (“Total Assets”) in equity investments selected for their potential to achieve capital appreciation over the long term. The Fund may invest in securities of companies of any capitalization. Although the Fund invests primarily in publicly traded U.S. securities, it may invest up to 25% of its Total Assets in foreign securities, including securities of issuers in countries with emerging markets or economies (“emerging countries”) and securities quoted in foreign currencies.

The Fund seeks to achieve its investment objective by investing, under normal circumstances, in approximately 30-40 companies that are considered by the Investment Adviser to be positioned for long-term growth. The Fund’s fundamental equity growth investment process involves evaluating potential investments based on specific characteristics believed to indicate a high-quality business with sustainable growth, including strong business franchises, favorable long-term prospects, and excellent management. The Investment Adviser will also consider valuation of companies when determining whether to buy and/or sell securities. The Investment Adviser may decide to sell a position for various reasons, including when a company’s fundamental outlook deteriorates, because of valuation and price considerations, for risk management purposes or when a company is deemed to be misallocating capital. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions.

The Fund may invest up to 10% of its Total Assets in fixed income securities, such as government, corporate and bank debt obligations.
The Fund's benchmark index is the Russell 1000^® Growth Index.

Principal Risks of the Fund

Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing.

Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles.

Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s net asset value (“NAV”) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio.

Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.

Mid-Cap and Small-Cap Risk.  Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks.

Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

Performance

The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund’s Class A Shares from year to year; and (b) how the average annual total returns of the Fund’s Class A, Class C, Institutional, Investor, Class R, Class R6 and Class T Shares compare to those of a broad-based securities market index. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus.

The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

The after-tax returns are for Class A Shares only. The after-tax returns for Class C, Institutional, Investor, Class R6 and Class T Shares, and returns for Class R Shares (which are offered exclusively to employee benefit plans), will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[1] The Fund’s “Management Fees” have been restated to reflect current fees.

[2] The “Other Expenses” for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[3] The Investment Adviser has agreed to reduce or limit "Other Expenses" (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% of the Fund's average daily net assets. Additionally, Goldman Sachs & Co. LLC ("Goldman Sachs"), the Fund's transfer agent, has agreed to waive a portion of its transfer agency fee (a component of "Other Expenses") equal to 0.03% as an annual percentage rate of the average daily net assets attributable to Class A, Class C, Investor, Class R and Class T Shares of the Fund. These arrangements will remain in effect through at least December 29, 2018, and prior to such date, the Investment Adviser and Goldman Sachs may not terminate the arrangements without the approval of the Board of Trustees.

[4] After Fee Waiver and Expense Limitation

[1] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares’ inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[2] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares’ inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

Expense Narrative [Text Block]	rr_ExpenseNarrativeTextBlock	This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class A or Class T Shares if you invest at least $50,000 or $250,000, respectively, in Goldman Sachs Funds. More information about these and other discounts is available from your financial professional and in “Shareholder Guide—Common Questions Applicable to the Purchase of Class A Shares” beginning on page 46 and “Shareholder Guide—Common Questions Applicable to the Purchase of Class T Shares” beginning on page 50 and in Appendix C—Additional Information About Sales Charge Variations, Waivers and Discounts on page 86 of the Prospectus and “Other Information Regarding Maximum Sales Charge, Purchases, Redemptions, Exchanges and Dividends” beginning on page B-106 of the Fund’s Statement of Additional Information (“SAI”).

Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	Portfolio Turnover
Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended August 31, 2017 was 54% of the average value of its portfolio.
Portfolio Turnover, Rate	rr_PortfolioTurnoverRate	54.00%
Expenses Deferred Charges [Text Block]	rr_ExpensesDeferredChargesTextBlock	A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.
Expense Breakpoint Discounts [Text]	rr_ExpenseBreakpointDiscounts	You may qualify for sales charge discounts on purchases of Class A or Class T Shares if you invest at least $50,000 or $250,000, respectively, in Goldman Sachs Funds. More information about these and other discounts is available from your financial professional and in “Shareholder Guide—Common Questions Applicable to the Purchase of Class A Shares” beginning on page 46 and “Shareholder Guide—Common Questions Applicable to the Purchase of Class T Shares” beginning on page 50 and in Appendix C—Additional Information About Sales Charge Variations, Waivers and Discounts on page 86 of the Prospectus and “Other Information Regarding Maximum Sales Charge, Purchases, Redemptions, Exchanges and Dividends” beginning on page B-106 of the Fund’s Statement of Additional Information (“SAI”).
Other Expenses, New Fund, Based on Estimates [Text]	rr_OtherExpensesNewFundBasedOnEstimates	The “Other Expenses” for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.
Expenses Restated to Reflect Current [Text]	rr_ExpensesRestatedToReflectCurrent	The Fund’s “Management Fees” have been restated to reflect current fees.
Expense Example [Heading]	rr_ExpenseExampleHeading	Expense Example
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Investor, Class R, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Investor, Class R, Class R6 and/or Class T Shares at the end of those periods, unless otherwise stated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the fee waiver and expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]	rr_StrategyHeading	Principal Strategy
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests, under normal circumstances, at least 90% of its total assets measured at time of purchase (“Total Assets”) in equity investments selected for their potential to achieve capital appreciation over the long term. The Fund may invest in securities of companies of any capitalization. Although the Fund invests primarily in publicly traded U.S. securities, it may invest up to 25% of its Total Assets in foreign securities, including securities of issuers in countries with emerging markets or economies (“emerging countries”) and securities quoted in foreign currencies. The Fund seeks to achieve its investment objective by investing, under normal circumstances, in approximately 30-40 companies that are considered by the Investment Adviser to be positioned for long-term growth. The Fund’s fundamental equity growth investment process involves evaluating potential investments based on specific characteristics believed to indicate a high-quality business with sustainable growth, including strong business franchises, favorable long-term prospects, and excellent management. The Investment Adviser will also consider valuation of companies when determining whether to buy and/or sell securities. The Investment Adviser may decide to sell a position for various reasons, including when a company’s fundamental outlook deteriorates, because of valuation and price considerations, for risk management purposes or when a company is deemed to be misallocating capital. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions. The Fund may invest up to 10% of its Total Assets in fixed income securities, such as government, corporate and bank debt obligations. The Fund's benchmark index is the Russell 1000® Growth Index.
Risk [Heading]	rr_RiskHeading	Principal Risks of the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing. Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles. Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s net asset value (“NAV”) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio. Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets. Mid-Cap and Small-Cap Risk.  Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks. Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

Risk Not Insured Depository Institution [Text]	rr_RiskNotInsuredDepositoryInstitution	An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency.
Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	Performance
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund’s Class A Shares from year to year; and (b) how the average annual total returns of the Fund’s Class A, Class C, Institutional, Investor, Class R, Class R6 and Class T Shares compare to those of a broad-based securities market index. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus. The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

Bar Chart Closing [Text Block]	rr_BarChartClosingTextBlock	The total return for Class A Shares for the 9-month period ended September 30, 2017 was 20.18%. Best Quarter Q2 ‘09          +20.85% Worst Quarter Q4 ‘08          –31.57%

Performance Table Does Reflect Sales Loads	rr_PerformanceTableDoesReflectSalesLoads	Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[2] The Fund’s “Management Fees” have been restated to reflect current fees.

[3] The “Other Expenses” for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[4] The Investment Adviser has agreed to reduce or limit "Other Expenses" (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% of the Fund's average daily net assets. Additionally, Goldman Sachs & Co. LLC ("Goldman Sachs"), the Fund's transfer agent, has agreed to waive a portion of its transfer agency fee (a component of "Other Expenses") equal to 0.03% as an annual percentage rate of the average daily net assets attributable to Class A, Class C, Investor, Class R and Class T Shares of the Fund. These arrangements will remain in effect through at least December 29, 2018, and prior to such date, the Investment Adviser and Goldman Sachs may not terminate the arrangements without the approval of the Board of Trustees.

[5] After Fee Waiver and Expense Limitation

[6] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares’ inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[7] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares’ inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

Goldman Sachs Flexible Cap Fund

Goldman Sachs Flexible Cap Fund—Summary

Investment Objective

The Goldman Sachs Flexible Cap Fund (formerly Goldman Sachs Flexible Cap Growth Fund) (the “Fund”) seeks long-term growth of capital.

Fees and Expenses of the Fund

This table describes the fees and expenses that you may pay if you buy and hold shares of the Fund. You may qualify for sales charge discounts on purchases of Class A or Class T Shares if you invest at least $50,000 or $250,000, respectively, in Goldman Sachs Funds.

Expense Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Investor, Class R, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Investor, Class R, Class R6 and/or Class T Shares at the end of those periods, unless otherwise stated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the fee waiver and expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Assuming complete redemption at end of period

Expense Example - Goldman Sachs Flexible Cap Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A Shares	642	1,157	1,699	3,172
Class C Shares	273	868	1,587	3,494
Institutional Shares	60	526	1,019	2,378
Investor Shares	72	566	1,088	2,521
Class R Shares	122	718	1,341	3,021
Class R6 Shares	59	523	1,014	2,368
Class T Shares	344	877	1,435	2,955

Assuming no redemption

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
Goldman Sachs Flexible Cap Fund | Class C Shares | USD ($)	173	868	1,587	3,494

Portfolio Turnover

The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended August 31, 2017 was 47% of the average value of its portfolio.

Principal Strategy

The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at time of purchase) (“Net Assets”) in equity investments in small-, mid- and large-cap issuers. Although the Fund invests primarily in publicly traded U.S. securities, it may invest up to 25% of its Net Assets in foreign securities, including securities of issuers in countries with emerging markets or economies (“emerging countries”) and securities quoted in foreign currencies. The Fund may also invest in privately held companies and companies that only recently began to trade publicly.

The Fund seeks to achieve its investment objective by investing, under normal circumstances, in companies that are considered by the Investment Adviser to be positioned for long-term growth of capital. The Investment Adviser uses a combination of fundamental research and quantitative factors to achieve its investment objective. The Fund’s fundamental equity growth investment process involves evaluating potential investments based on specific characteristics believed to identify high-quality businesses with sustainable growth prospects, including strong business franchises, favorable long-term prospects, and excellent management. Investments will be further evaluated for their exposures to quantitative factors, such as, for example, valuation, profitability and volatility, to seek to enhance the Fund’s risk adjusted returns. Risk management, portfolio construction and sizing of positions will be informed by portfolio-level quantitative factor considerations. The Investment Adviser may decide to sell a position for various reasons, including when a company’s fundamental outlook deteriorates, because of valuation and price considerations, for risk management purposes, or when a company is deemed to be misallocating capital. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions.

The Fund may invest up to 20% of its Net Assets in fixed income securities (including high yield fixed income securities), such as government, corporate and bank debt obligations.

The Fund’s benchmark index is the S&P 500^® Index.

Principal Risks of the Fund

Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing.

Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles.

Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s net asset value (“NAV”) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio.

Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.

Mid-Cap and Small-Cap Risk.  Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks.

Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

Performance

The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund’s Class A Shares from year to year; and (b) how the average annual total returns of the Fund’s Class A, Class C, Institutional, Investor, Class R, Class R6 and Class T Shares compare to those of a broad-based securities market index. Through August 31, 2017, the Fund had been known as the Goldman Sachs Flexible Cap Growth Fund, and certain of its principal investment strategies differed. Performance information set forth below reflects the performance resulting from the Fund’s former strategies prior to that date. In addition, as of that date, the Fund’s benchmark was changed from the Russell 3000^® Growth Index to the S&P 500^® Index. The Investment Adviser believes that the S&P 500^® Index is a more appropriate index against which to measure performance in light of the changes to the Fund’s investment strategy. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus.

The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

The after-tax returns are for Class A Shares only. The after-tax returns for Class C, Institutional, Investor, Class R6 and Class T Shares, and returns for Class R Shares (which are offered exclusively to employee benefit plans), will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[1] The Fund’s “Management Fees” have been restated to reflect current fees.

[2] The “Other Expenses” for Class A, Class C, Investor, Class R and Class R6 Shares have been restated to reflect current fees, and the “Other Expenses” for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[3] The Investment Adviser has agreed to reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% of the Fund’s average daily net assets. Additionally, Goldman Sachs & Co. LLC (“Goldman Sachs”), the Fund’s transfer agent, has agreed to waive a portion of its transfer agency fee (a component of “Other Expenses”) equal to 0.03% as an annual percentage rate of the average daily net assets attributable to Class A, Class C, Investor, Class R and Class T Shares of the Fund. These arrangements will remain in effect through at least December 29, 2018, and prior to such date, the Investment Adviser and Goldman Sachs may not terminate the arrangements without the approval of the Board of Trustees.

[4] After Fee Waiver and Expense Limitation

[1] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares' inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[2] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares’ inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing. Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles. Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s net asset value (“NAV”) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would.

Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets. Mid-Cap and Small-Cap Risk.  Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks. Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund’s Class A Shares from year to year; and (b) how the average annual total returns of the Fund’s Class A, Class C, Institutional, Investor, Class R, Class R6 and Class T Shares compare to those of a broad-based securities market index. Through August 31, 2017, the Fund had been known as the Goldman Sachs Flexible Cap Growth Fund, and certain of its principal investment strategies differed. Performance information set forth below reflects the performance resulting from the Fund’s former strategies prior to that date. In addition, as of that date, the Fund’s benchmark was changed from the Russell 3000® Growth Index to the S&P 500® Index. The Investment Adviser believes that the S&P 500® Index is a more appropriate index against which to measure performance in light of the changes to the Fund’s investment strategy. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus. The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

Performance Table Does Reflect Sales Loads	rr_PerformanceTableDoesReflectSalesLoads	Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[2] The Fund’s “Management Fees” have been restated to reflect current fees.

[3] The “Other Expenses” for Class A, Class C, Investor, Class R and Class R6 Shares have been restated to reflect current fees, and the “Other Expenses” for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[4] The Investment Adviser has agreed to reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% of the Fund’s average daily net assets. Additionally, Goldman Sachs & Co. LLC (“Goldman Sachs”), the Fund’s transfer agent, has agreed to waive a portion of its transfer agency fee (a component of “Other Expenses”) equal to 0.03% as an annual percentage rate of the average daily net assets attributable to Class A, Class C, Investor, Class R and Class T Shares of the Fund. These arrangements will remain in effect through at least December 29, 2018, and prior to such date, the Investment Adviser and Goldman Sachs may not terminate the arrangements without the approval of the Board of Trustees.

[5] After Fee Waiver and Expense Limitation

[6] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares' inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[7] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares’ inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

Expense Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares at the end of those periods, unless otherwise stated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the expense limitation arrangement for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Assuming complete redemption at end of period

Class A Shares	660	914	1,189	1,969

Portfolio Turnover

The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended August 31, 2017 was 54% of the average value of its portfolio.

Principal Strategy

The Fund invests, under normal circumstances, at least 90% of its total assets measured at time of purchase (“Total Assets”) in equity investments. Although the Fund invests primarily in publicly traded U.S. securities, it may invest up to 25% of its Total Assets in foreign securities, including securities of issuers in countries with emerging markets or economies (“emerging countries”) and securities quoted in foreign currencies.

The Fund seeks to achieve its investment objective by investing, under normal circumstances, in approximately 50-70 companies that are considered by the Investment Adviser to be positioned for long-term growth. The Fund’s fundamental equity growth investment process involves evaluating potential investments based on specific characteristics believed to indicate a high-quality business with sustainable growth, including strong business franchises, favorable long-term prospects, and excellent management. The Investment Adviser will also consider valuation of companies when determining whether to buy and/or sell securities. The Investment Adviser may decide to sell a position for various reasons, including when a company’s fundamental outlook deteriorates, because of valuation and price considerations, for risk management purposes, or when a company is deemed to be misallocating capital. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions.

The Fund may invest up to 10% of its Total Assets in fixed income securities, such as government, corporate and bank debt obligations.

The Fund’s benchmark index is the Russell 1000^® Growth Index.

Principal Risks of the Fund

Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing.

Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles.

Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s net asset value (“NAV”) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio.

Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.

Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

Performance

The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund’s Class A Shares from year to year; and (b) how the average annual total returns of the Fund’s Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and Class T Shares compare to those of a broad-based securities market index. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus.

The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

The after-tax returns are for Class A Shares only. The after-tax returns for Class C, Institutional, Service, Investor, Class R6 and Class T Shares, and returns for Class R Shares (which are offered exclusively to employee benefit plans), will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[1] The Fund’s “Management Fees” have been restated to reflect current fees.

[2] The “Other Expenses” for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[3] The Investment Adviser has agreed to reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, shareholder administration fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% of the Fund’s average daily net assets. This arrangement will remain in effect through at least December 29, 2018, and prior to such date the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees.

[4] After Expense Limitation

[1] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares’ inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[2] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares’ inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[2] The Fund’s “Management Fees” have been restated to reflect current fees.

[3] The “Other Expenses” for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[4] The Investment Adviser has agreed to reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, shareholder administration fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% of the Fund’s average daily net assets. This arrangement will remain in effect through at least December 29, 2018, and prior to such date the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees.

[5] After Expense Limitation

[6] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares’ inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[7] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares’ inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

Expense Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares at the end of those periods, unless otherwise stated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the fee waiver and expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Assuming complete redemption at end of period

Expense Example - Goldman Sachs Growth Opportunities Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A Shares	676	954	1,253	2,101
Class C Shares	309	658	1,134	2,447
Institutional Shares	99	311	541	1,200
Service Shares	150	467	807	1,768
Investor Shares	108	350	611	1,358
Class R Shares	159	505	876	1,917
Class R6 Shares	98	308	535	1,189
Class T Shares	380	667	976	1,850

Assuming no redemption

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
Goldman Sachs Growth Opportunities Fund | Class C Shares | USD ($)	209	658	1,134	2,447

Portfolio Turnover

The Fund pays transaction costs when it buys and sells securities or instruments (i.e., "turns over" its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund's performance. The Fund's portfolio turnover rate for the fiscal year ended August 31, 2017 was 61% of the average value of its portfolio.

Principal Strategy

The Fund invests, under normal circumstances, at least 90% of its total assets measured at the time of purchase (“Total Assets”) in equity investments with a primary focus on mid-cap companies. The Fund seeks to achieve its investment objective by investing, under normal circumstances, in approximately 60-80 companies that are considered by the Investment Adviser to be positioned for long-term growth. Although the Fund invests primarily in publicly traded U.S. securities, it may invest up to 25% of its Total Assets in foreign securities, including securities of issuers in countries with emerging markets or economies (“emerging countries”) and securities quoted in foreign currencies. The Fund may also invest in privately held companies and companies that only recently began to trade publicly.

The Fund’s fundamental equity growth investment process involves evaluating potential investments based on specific characteristics believed to indicate a high-quality business with sustainable growth, including strong business franchises, favorable long-term prospects, and excellent management. The Investment Adviser will also consider valuation of companies when determining whether to buy and/or sell securities. The Investment Adviser may decide to sell a position for various reasons, including when a company’s fundamental outlook deteriorates, because of valuation and price considerations, for risk management purposes, or when a company is deemed to be misallocating capital or a company no longer fits within the Fund’s definition of a mid cap company. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions.

The Fund’s benchmark index is the Russell Midcap^® Growth Index.

Principal Risks of the Fund

Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing.

Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles.

Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s net asset value (“NAV”) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio.

Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.

Mid-Cap and Small-Cap Risk.  Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks.

Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

Performance

The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund’s Class A Shares from year to year; and (b) how the average annual total returns of the Fund’s Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and Class T Shares compare to those of a broad-based securities market index. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus.

The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

The after-tax returns are for Class A Shares only. The after-tax returns for Class C, Institutional, Service, Investor, Class R6 and Class T Shares, and returns for Class R Shares (which are offered exclusively to employee benefit plans), will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[1] The Fund’s “Management Fees” have been restated to reflect current fees.

[2] The “Other Expenses” for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[3] The Investment Adviser has agreed to reduce or limit "Other Expenses" (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, shareholder administration fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.014% of the Fund's average daily net assets. Additionally, Goldman Sachs & Co. LLC ("Goldman Sachs"), the Fund's transfer agent, has agreed to waive a portion of its transfer agency fee (a component of "Other Expenses") equal to 0.05% as an annual percentage rate of the average daily net assets attributable to Class A, Class C, Investor, Class R and Class T Shares of the Fund. These arrangements will remain in effect through at least December 29, 2018, and prior to such date, the Investment Adviser and Goldman Sachs may not terminate the arrangements without the approval of the Board of Trustees.

[4] After Fee Waiver and Expense Limitation

[1] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares' inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[2] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares’ inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

You may qualify for sales charge discounts on purchases of Class A or Class T Shares if you invest at least $50,000 or $250,000, respectively, in Goldman Sachs Funds. More information about these and other discounts is available from your financial professional and in “Shareholder Guide—Common Questions Applicable to the Purchase of Class A Shares” beginning on page 38 and “Shareholder Guide—Common Questions Applicable to the Purchase of Class T Shares” beginning on page 40 and in Appendix C—Additional Information About Sales Charge Variations, Waivers and Discounts on page 74 of the Prospectus and “Other Information Regarding Maximum Sales Charge, Purchases, Redemptions, Exchanges and Dividends” beginning on page B-106 of the Fund’s Statement of Additional Information (“SAI”).

Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs when it buys and sells securities or instruments (i.e., "turns over" its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund's performance. The Fund's portfolio turnover rate for the fiscal year ended August 31, 2017 was 61% of the average value of its portfolio.

Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares at the end of those periods, unless otherwise stated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the fee waiver and expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example, No Redemption, By Year, Caption [Text]	rr_ExpenseExampleNoRedemptionByYearCaption	Assuming no redemption
Strategy [Heading]	rr_StrategyHeading	Principal Strategy
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests, under normal circumstances, at least 90% of its total assets measured at the time of purchase (“Total Assets”) in equity investments with a primary focus on mid-cap companies. The Fund seeks to achieve its investment objective by investing, under normal circumstances, in approximately 60-80 companies that are considered by the Investment Adviser to be positioned for long-term growth. Although the Fund invests primarily in publicly traded U.S. securities, it may invest up to 25% of its Total Assets in foreign securities, including securities of issuers in countries with emerging markets or economies (“emerging countries”) and securities quoted in foreign currencies. The Fund may also invest in privately held companies and companies that only recently began to trade publicly. The Fund’s fundamental equity growth investment process involves evaluating potential investments based on specific characteristics believed to indicate a high-quality business with sustainable growth, including strong business franchises, favorable long-term prospects, and excellent management. The Investment Adviser will also consider valuation of companies when determining whether to buy and/or sell securities. The Investment Adviser may decide to sell a position for various reasons, including when a company’s fundamental outlook deteriorates, because of valuation and price considerations, for risk management purposes, or when a company is deemed to be misallocating capital or a company no longer fits within the Fund’s definition of a mid cap company. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions. The Fund’s benchmark index is the Russell Midcap® Growth Index.
Risk [Heading]	rr_RiskHeading	Principal Risks of the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing. Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles. Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s net asset value (“NAV”) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio. Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets. Mid-Cap and Small-Cap Risk.  Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks. Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.
Risk Lose Money [Text]	rr_RiskLoseMoney	Loss of money is a risk of investing in the Fund.
Risk Not Insured Depository Institution [Text]	rr_RiskNotInsuredDepositoryInstitution	An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency.
Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	Performance

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[2] The Fund’s “Management Fees” have been restated to reflect current fees.

[3] The “Other Expenses” for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[4] The Investment Adviser has agreed to reduce or limit "Other Expenses" (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, shareholder administration fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.014% of the Fund's average daily net assets. Additionally, Goldman Sachs & Co. LLC ("Goldman Sachs"), the Fund's transfer agent, has agreed to waive a portion of its transfer agency fee (a component of "Other Expenses") equal to 0.05% as an annual percentage rate of the average daily net assets attributable to Class A, Class C, Investor, Class R and Class T Shares of the Fund. These arrangements will remain in effect through at least December 29, 2018, and prior to such date, the Investment Adviser and Goldman Sachs may not terminate the arrangements without the approval of the Board of Trustees.

[5] After Fee Waiver and Expense Limitation

[6] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares' inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[7] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares’ inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

Expense Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares at the end of those periods, unless otherwise stated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the fee waiver and expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Assuming complete redemption at end of period

Expense Example - Goldman Sachs Small/Mid Cap Growth Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A Shares	672	937	1,221	2,029
Class C Shares	305	640	1,101	2,377
Institutional Shares	93	290	504	1,120
Service Shares	144	446	771	1,691
Investor Shares	104	331	576	1,280
Class R Shares	155	487	842	1,843
Class R6 Shares	92	287	498	1,108
Class T Shares	376	649	942	1,776

Assuming no redemption

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
Goldman Sachs Small/Mid Cap Growth Fund | Class C Shares | USD ($)	205	640	1,101	2,377

Portfolio Turnover

The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended August 31, 2017 was 60% of the average value of its portfolio.

Principal Strategy

The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at the time of purchase) (“Net Assets”) in a diversified portfolio of equity investments in small and mid-cap issuers. Small or mid-cap issuers are issuers with public stock market capitalizations (based upon shares available for trading on an unrestricted basis) within the outside range of the market capitalizations of companies constituting the Russell 2000^® Growth Index and the Russell Midcap^® Growth Index, as last reported by the indexes prior to the time of investment. If the market capitalization of a company held by the Fund moves outside this range, the Fund may, but is not required to, sell the securities. As of September 30, 2017, the outside capitalization range of the companies in these indexes was between $30 million and $60 billion. The Fund seeks to achieve its investment objective by investing, under normal circumstances, in approximately 90-125 companies that are considered by the Investment Adviser to be positioned for long-term growth. Although the Fund invests primarily in publicly traded U.S. securities, it may invest up to 25% of its Net Assets in foreign securities, including securities of issuers in countries with emerging markets or economies (“emerging countries”) and securities quoted in foreign currencies. The Fund may also invest in privately held companies and companies that only recently began to trade publicly.

The Fund’s fundamental equity growth investment process involves evaluating potential investments based on specific characteristics believed to indicate a high-quality business with sustainable growth, including strong business franchises, favorable long-term prospects, and excellent management. The Investment Adviser will also consider valuation of companies when determining whether to buy and/or sell securities. The Investment Adviser may decide to sell a position for various reasons, including when a company’s fundamental outlook deteriorates, because of valuation and price considerations, for risk management purposes, or when a company is deemed to be misallocating capital or a company no longer fits within the Fund’s definition of a small/mid cap company. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions.

The Fund may invest up to 20% of its Net Assets in fixed income securities, such as government, corporate and bank debt obligations.

The Fund’s benchmark index is the Russell 2500^® Growth Index.

Principal Risks of the Fund

Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing.

Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles.

Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s net asset value (“NAV”) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio.

Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.

Mid-Cap and Small-Cap Risk.  Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks.

Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

Performance

The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund’s Class A Shares from year to year; and (b) how the average annual total returns of the Fund’s Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and Class T Shares compare to those of a broad-based securities market index. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus.

The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

The after-tax returns are for Class A Shares only. The after-tax returns for Class C, Institutional, Service, Investor, Class R6 and Class T Shares, and returns for Class R Shares (which are offered exclusively to employee benefit plans), will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[1] The Fund’s “Management Fees” have been restated to reflect current fees.

[2] The “Other Expenses” for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[3] The Investment Adviser has agreed to reduce or limit "Other Expenses" (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, shareholder administration fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.064% of the Fund's average daily net assets. Additionally, Goldman Sachs & Co. LLC ("Goldman Sachs"), the Fund's transfer agent, has agreed to waive a portion of its transfer agency fee (a component of "Other Expenses") equal to 0.03% as an annual percentage rate of the average daily net assets attributable to Class A, Class C, Investor, Class R and Class T Shares of the Fund. These arrangements will remain in effect through at least December 29, 2018, and prior to such date, the Investment Adviser and Goldman Sachs may not terminate the arrangements without the approval of the Board of Trustees.

[4] After Fee Waiver and Expense Limitation

[1] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares' inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[2] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares’ inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

More information about these and other discounts is available from your financial professional and in “Shareholder Guide—Common Questions Applicable to the Purchase of Class A Shares” beginning on page 38 and “Shareholder Guide—Common Questions Applicable to the Purchase of Class T Shares” beginning on page 40 and in Appendix C—Additional Information About Sales Charge Variations, Waivers and Discounts on page 74 of the Prospectus and “Other Information Regarding Maximum Sales Charge, Purchases, Redemptions, Exchanges and Dividends” beginning on page B-106 of the Fund’s Statement of Additional Information (“SAI”).

Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended August 31, 2017 was 60% of the average value of its portfolio.

Expense Example [Heading]	rr_ExpenseExampleHeading	Expense Example
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares at the end of those periods, unless otherwise stated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the fee waiver and expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]	rr_StrategyHeading	Principal Strategy
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at the time of purchase) (“Net Assets”) in a diversified portfolio of equity investments in small and mid-cap issuers. Small or mid-cap issuers are issuers with public stock market capitalizations (based upon shares available for trading on an unrestricted basis) within the outside range of the market capitalizations of companies constituting the Russell 2000® Growth Index and the Russell Midcap® Growth Index, as last reported by the indexes prior to the time of investment. If the market capitalization of a company held by the Fund moves outside this range, the Fund may, but is not required to, sell the securities. As of September 30, 2017, the outside capitalization range of the companies in these indexes was between $30 million and $60 billion. The Fund seeks to achieve its investment objective by investing, under normal circumstances, in approximately 90-125 companies that are considered by the Investment Adviser to be positioned for long-term growth. Although the Fund invests primarily in publicly traded U.S. securities, it may invest up to 25% of its Net Assets in foreign securities, including securities of issuers in countries with emerging markets or economies (“emerging countries”) and securities quoted in foreign currencies. The Fund may also invest in privately held companies and companies that only recently began to trade publicly. The Fund’s fundamental equity growth investment process involves evaluating potential investments based on specific characteristics believed to indicate a high-quality business with sustainable growth, including strong business franchises, favorable long-term prospects, and excellent management. The Investment Adviser will also consider valuation of companies when determining whether to buy and/or sell securities. The Investment Adviser may decide to sell a position for various reasons, including when a company’s fundamental outlook deteriorates, because of valuation and price considerations, for risk management purposes, or when a company is deemed to be misallocating capital or a company no longer fits within the Fund’s definition of a small/mid cap company. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions. The Fund may invest up to 20% of its Net Assets in fixed income securities, such as government, corporate and bank debt obligations. The Fund’s benchmark index is the Russell 2500® Growth Index.
Risk [Heading]	rr_RiskHeading	Principal Risks of the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing. Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles. Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s net asset value (“NAV”) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio. Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets. Mid-Cap and Small-Cap Risk.  Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks. Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	Performance
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund’s Class A Shares from year to year; and (b) how the average annual total returns of the Fund’s Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and Class T Shares compare to those of a broad-based securities market index. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus. The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[2] The Fund’s “Management Fees” have been restated to reflect current fees.

[3] The “Other Expenses” for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[4] The Investment Adviser has agreed to reduce or limit "Other Expenses" (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, shareholder administration fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.064% of the Fund's average daily net assets. Additionally, Goldman Sachs & Co. LLC ("Goldman Sachs"), the Fund's transfer agent, has agreed to waive a portion of its transfer agency fee (a component of "Other Expenses") equal to 0.03% as an annual percentage rate of the average daily net assets attributable to Class A, Class C, Investor, Class R and Class T Shares of the Fund. These arrangements will remain in effect through at least December 29, 2018, and prior to such date, the Investment Adviser and Goldman Sachs may not terminate the arrangements without the approval of the Board of Trustees.

[5] After Fee Waiver and Expense Limitation

[6] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares' inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[7] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares’ inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

Expense Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Service, Investor, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Service, Investor, Class R6 and/or Class T Shares at the end of those periods, unless otherwise stated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the fee waiver and expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Assuming complete redemption

Expense Example - Goldman Sachs Technology Opportunities Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A Shares	682	978	1,295	2,193
Class C Shares	315	683	1,177	2,537
Institutional Shares	100	331	581	1,298
Service Shares	151	487	847	1,860
Investor Shares	114	375	656	1,458
Class R6 Shares	99	328	576	1,286
Class T Shares	386	692	1,019	1,945

Assuming no redemption

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
Goldman Sachs Technology Opportunities Fund | Class C Shares | USD ($)	215	683	1,177	2,537

Portfolio Turnover

The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended August 31, 2017 was 19% of the average value of its portfolio.

Principal Strategy

The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at time of purchase) (“Net Assets”) in equity investments in technology companies, as described below. The Fund seeks to achieve its investment objective by investing, under normal circumstances, in approximately 30-40 companies that are considered by the Investment Adviser to benefit from the proliferation of technology. Although the Fund invests primarily in publicly traded U.S. securities, it may invest up to 25% of its total assets measured at the time of purchase (“Total Assets”) in foreign securities, including securities of issuers in countries with emerging markets or economies (“emerging countries”) and securities quoted in foreign currencies. The Fund may also invest in privately held companies and companies that only recently began to trade publicly.

The Fund’s fundamental equity growth investment process involves evaluating potential investments based on specific characteristics believed to indicate a high-quality business with sustainable growth, including strong business franchises, favorable long-term prospects, and excellent management. The Investment Adviser will also consider valuation of companies when determining whether to buy and/or sell securities. The Investment Adviser may decide to sell a position for various reasons, including when a company’s fundamental outlook deteriorates, because of valuation and price considerations, for risk management purposes, or when a company is deemed to be misallocating capital. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions.

The Fund intends to invest a substantial portion of its assets in technology companies. In general, the Investment Adviser defines a technology company as a high-quality technology, services, media or telecommunications company that adopts or uses technology to improve its cost structure, revenue opportunities or competitive advantage. The Investment Adviser seeks to identify technology companies that exhibit many of the following characteristics:

• Strong brand name
• Dominant market share
• Recurring revenue streams
• Free cash flow generation
• Long product life cycle
• Enduring competitive advantage
• Excellent management

The Investment Adviser seeks to identify technology companies that are promising growth businesses. These companies may grow revenue by increasing sales volumes, prices, customers and market share. The Internet is an example of a technology that the Investment Adviser believes will drive growth for many technology businesses. The Internet has had, and is expected to continue to have, a significant impact on the global economy, as it changes the way many companies operate. Benefits of the Internet for businesses may include global scalability, acquisition of new clients, new revenue sources and increased efficiencies. Technology companies adopting innovative Internet technologies to improve their business models include providers of infrastructure, software, hardware and services.

The Fund will invest at least 25% of its Total Assets in companies in one or more of the media, telecommunications, technology and/or Internet industries. Because of its focus on technology, telecommunications, Internet, services and media companies, the Fund’s investment performance will be closely tied to many factors which affect these companies. These factors include intense competition, consumer preferences, problems with product compatibility and government regulation. The Fund’s investments may experience significant price movements caused by disproportionate investor optimism or pessimism with little or no basis in fundamental economic conditions. The Fund may also invest in a relatively few number of issuers. As a result, the Fund’s net asset value (“NAV”) is more likely to have greater fluctuations than that of a fund which is more diversified or invests in other industries.

The Fund’s benchmark index is the S&P North American Technology Sector Index.

Principal Risks of the Fund

Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing.

Industry Concentration Risk.  The Fund concentrates its investments in specific industry sectors that have historically experienced substantial price volatility. The Fund is subject to greater risk of loss as a result of adverse economic, business, political, environmental or other developments than if its investments were diversified across different industry sectors. Securities of issuers held by the Fund may lack sufficient market liquidity to enable the Fund to sell the securities at an advantageous time or without a substantial drop in price.

Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles.

Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio.

Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.

Mid-Cap and Small-Cap Risk.  Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks.

Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

Technology Sector Risk.  The stock prices of technology and technology-related companies and therefore the value of the Fund may experience significant price movements as a result of intense market volatility, worldwide competition, consumer preferences, product compatibility, product obsolescence, government regulation, excessive investor optimism or pessimism, or other factors. The Fund may also invest in a relatively few number of issuers. Thus, the Fund may be more susceptible to adverse developments affecting any single issuer held in its portfolio and may be more susceptible to greater losses because of these developments.

Performance

The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund’s Class A Shares from year to year; and (b) how the average annual total returns of the Fund’s Class A, Class C, Institutional, Service, Investor, Class R6 and Class T Shares compare to those of a broad-based securities market index. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus.

The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

The after-tax returns are for Class A Shares only. The after-tax returns for Class C, Institutional, Service, Investor, Class R6 and Class T Shares, and returns for Class R6 Shares (which are offered exclusively to employee benefit plans), will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[1] The Fund’s “Management Fees” have been restated to reflect current fees.

[2] The “Other Expenses” for Class R6 and Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[3] The Investment Adviser has agreed to reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, shareholder administration fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% of the Fund’s average daily net assets. This arrangement will remain in effect through at least December 29, 2018, and prior to such date, the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees.

[4] After Expense Limitation

[1] Class R6 Shares commenced operations on December 29, 2017. Prior to that date, the performance of Class R6 Shares shown in the table above is that of Institutional Shares, including since inception performance as of Institutional Shares' inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[2] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares' inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

In general, the Investment Adviser defines a technology company as a high-quality technology, services, media or telecommunications company that adopts or uses technology to improve its cost structure, revenue opportunities or competitive advantage. The Investment Adviser seeks to identify technology companies that exhibit many of the following characteristics: Strong brand name Dominant market share Recurring revenue streams Free cash flow generation Long product life cycle Enduring competitive advantage Excellent management The Investment Adviser seeks to identify technology companies that are promising growth businesses. These companies may grow revenue by increasing sales volumes, prices, customers and market share. The Internet is an example of a technology that the Investment Adviser believes will drive growth for many technology businesses. The Internet has had, and is expected to continue to have, a significant impact on the global economy, as it changes the way many companies operate. Benefits of the Internet for businesses may include global scalability, acquisition of new clients, new revenue sources and increased efficiencies. Technology companies adopting innovative Internet technologies to improve their business models include providers of infrastructure, software, hardware and services. The Fund will invest at least 25% of its Total Assets in companies in one or more of the media, telecommunications, technology and/or Internet industries. Because of its focus on technology, telecommunications, Internet, services and media companies, the Fund’s investment performance will be closely tied to many factors which affect these companies. These factors include intense competition, consumer preferences, problems with product compatibility and government regulation. The Fund’s investments may experience significant price movements caused by disproportionate investor optimism or pessimism with little or no basis in fundamental economic conditions. The Fund may also invest in a relatively few number of issuers. As a result, the Fund’s net asset value (“NAV”) is more likely to have greater fluctuations than that of a fund which is more diversified or invests in other industries. The Fund’s benchmark index is the S&P North American Technology Sector Index.

Risk [Heading]	rr_RiskHeading	Principal Risks of the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing. Industry Concentration Risk.  The Fund concentrates its investments in specific industry sectors that have historically experienced substantial price volatility. The Fund is subject to greater risk of loss as a result of adverse economic, business, political, environmental or other developments than if its investments were diversified across different industry sectors. Securities of issuers held by the Fund may lack sufficient market liquidity to enable the Fund to sell the securities at an advantageous time or without a substantial drop in price. Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles. Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio. Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets. Mid-Cap and Small-Cap Risk.  Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks. Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future. Technology Sector Risk.  The stock prices of technology and technology-related companies and therefore the value of the Fund may experience significant price movements as a result of intense market volatility, worldwide competition, consumer preferences, product compatibility, product obsolescence, government regulation, excessive investor optimism or pessimism, or other factors. The Fund may also invest in a relatively few number of issuers. Thus, the Fund may be more susceptible to adverse developments affecting any single issuer held in its portfolio and may be more susceptible to greater losses because of these developments.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[2] The Fund’s “Management Fees” have been restated to reflect current fees.

[3] The “Other Expenses” for Class R6 and Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[4] The Investment Adviser has agreed to reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, shareholder administration fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% of the Fund’s average daily net assets. This arrangement will remain in effect through at least December 29, 2018, and prior to such date, the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees.

[5] After Expense Limitation

[6] Class R6 Shares commenced operations on December 29, 2017. Prior to that date, the performance of Class R6 Shares shown in the table above is that of Institutional Shares, including since inception performance as of Institutional Shares' inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares.

Expense Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares at the end of those periods, unless otherwise stated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the fee waiver and expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Assuming complete redemption at end of period

Expense Example - Goldman Sachs Equity Income Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A Shares	658	907	1,174	1,938
Class C Shares	290	609	1,053	2,288
Institutional Shares	75	255	451	1,016
Service Shares	125	412	719	1,593
Investor Shares	89	299	527	1,181

Class R6 Shares	74	252	445	1,004
Class T Shares	361	618	894	1,682

Assuming no redemption

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
Goldman Sachs Equity Income Fund | Class C Shares | USD ($)	190	609	1,053	2,288

Portfolio Turnover

The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended August 31, 2017 was 43% of the average value of its portfolio.

Principal Strategy

The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at the time of purchase) (“Net Assets”) in equity investments. The Fund will generally invest in equity securities that the Investment Adviser believes have favorable prospects for capital appreciation and/or dividend-paying ability. Although the Fund will invest primarily in publicly traded U.S. securities, including preferred and convertible securities, master limited partnerships (“MLPs”) and real estate investment trusts (“REITs”), it may invest up to 25% of its Net Assets in foreign securities, including securities of issuers in countries with emerging markets or economies (“emerging countries”) and securities quoted in foreign currencies. The Investment Adviser expects that the Fund’s investments will be weighted in favor of companies that pay dividends or other current distributions.

The Fund’s equity investment process involves: (1) using multiple industry-specific valuation metrics to identify real economic value and company potential in stocks, screened by valuation, profitability and business characteristics; (2) conducting in-depth company research and assessing overall business quality; and (3) buying those securities that a sector portfolio manager recommends, taking into account feedback from the rest of the portfolio management team. The Investment Adviser may decide to sell a position for various reasons, including valuation and price considerations, readjustment of the Investment Adviser’s outlook based on subsequent events, the Investment Adviser’s ongoing assessment of the quality and effectiveness of management, if new investment ideas offer the potential for better risk/reward profiles than existing holdings, or for risk management purposes. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions.

The Fund may also invest up to 20% of its Net Assets in fixed income securities, such as government, corporate and bank debt obligations.

The Fund seeks to generate additional cash flow and may reduce volatility by the sale of call options on the S&P 500^® Index or other regional stock market indices (or related exchange-traded funds (“ETFs”)).

The Fund expects that, under normal circumstances, it will sell call options in an amount that is between 0% and 30% of the value of the Fund’s portfolio. As the seller of the call options, the Fund will receive cash (the “premium”) from the purchaser. If the purchaser exercises the option, the Fund pays the purchaser the difference between the price of the index and the exercise price of the option. The premium, the exercise price and the market price of the index determine the gain or loss realized by the Fund as the seller of the call option.

During periods in which the U.S. equity markets are generally unchanged or falling, or in a modestly rising market where the income from premiums exceeds the aggregate appreciation of the underlying index over its exercise price, a diversified portfolio receiving premiums from its call option writing strategy may outperform the same portfolio without such an options strategy. However, in rising markets where the aggregate appreciation of the underlying index over its exercise price exceeds the income from premiums, a portfolio with a call writing strategy could significantly underperform the same portfolio without the options.

The Fund’s benchmark index is the Russell 1000^® Value Index.

Principal Risks of the Fund

Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing.

Foreign and Emerging Countries Risk.  Foreign securities may be subject to risk of loss because of more or less foreign government regulation, less public information and less economic, political and social stability in the countries in which the Fund invests. The imposition of exchange controls, sanctions, confiscations, trade restrictions (including tariffs) and other government restrictions by the United States and other governments, or from problems in share registration, settlement or custody, may also result in losses. Foreign risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. These risks may be more pronounced in connection with the Fund’s investments in securities of issuers located in emerging countries.

Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles. Value stocks are those believed to be undervalued in comparison to their peers, due to market, company-specific or other factors.

Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio.

Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.

Master Limited Partnership Risk.  Investments in securities of an MLP involve risks that differ from investments in common stock, including risks related to limited control and limited rights to vote on matters affecting the MLP. Certain MLP securities may trade in lower volumes due to their smaller capitalizations, and may be subject to more abrupt or erratic price movements and lower market liquidity. MLPs are generally considered interest-rate sensitive investments. During periods of interest rate volatility, these investments may not provide attractive returns.

Investments in securities of an MLP also include tax-related risks. For example, to the extent a distribution received by the Fund from an MLP is treated as a return of capital, the Fund’s adjusted tax basis in the interests of the MLP may be reduced, which will result in an increase in an amount of income or gain (or decrease in the amount of loss) that will be recognized by the Fund for tax purposes upon the sale of any such interests or upon subsequent distributions in respect of such interests.

Option Writing Risk.  Writing (selling) call options limits the opportunity to profit from an increase in the market value of stocks in exchange for up-front cash (the premium) at the time of selling the call option. In a rising market, the Fund could significantly underperform the market. Furthermore, the Fund’s call option writing strategies may not fully protect it against market declines because the Fund will continue to bear the risk of a decline in the value of its portfolio securities. In a sharply-falling equity market, the Fund will likely also experience sharp declines in its net asset value (“NAV”).

REIT Risk.  Risks associated with investments such as REITs in the real estate industry include, among others: possible declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage financing, variations in rental income, neighborhood values or the appeal of property to tenants; interest rates; overbuilding; extended vacancies of properties; increases in competition, property taxes and operating expenses; and changes in zoning laws. REITs whose underlying properties are concentrated in a particular industry or geographic region are subject to risks affecting such industries and regions. The securities of REITs involve greater risks than those associated with larger, more established companies and may be subject to more abrupt or erratic price movements because of interest rate changes, economic conditions and other factors. Securities of such issuers may lack sufficient market liquidity to enable the Fund to effect sales at an advantageous time or without a substantial drop in price.

Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

Performance

The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund’s Class A Shares from year to year; and (b) how the average annual total returns of the Fund’s Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and Class T Shares compare to those of a broad-based securities market index. Prior to June 20, 2017, the Fund had been known as the Goldman Sachs Growth and Income Fund, and certain of its principal investment strategies differed. Performance information set forth below prior to June 20, 2017 reflects the performance resulting from the Fund’s former strategies. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus.

The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

The after-tax returns are for Class A Shares only. The after-tax returns for Class C, Institutional, Service, Investor, Class R6 and Class T Shares, and returns for Class R Shares (which are offered exclusively to employee benefit plans), will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[1] The Fund’s “Management Fees” have been restated to reflect current fees.

[2] The “Other Expenses” for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[3] The Investment Adviser has agreed to reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, shareholder administration fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% of the Fund’s average daily net assets. This arrangement will remain in effect through at least December 29, 2018, and prior to such date the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees.

[4] After Expense Limitation

[1] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares’ inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[2] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares’ inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets. Master Limited Partnership Risk.  Investments in securities of an MLP involve risks that differ from investments in common stock, including risks related to limited control and limited rights to vote on matters affecting the MLP. Certain MLP securities may trade in lower volumes due to their smaller capitalizations, and may be subject to more abrupt or erratic price movements and lower market liquidity. MLPs are generally considered interest-rate sensitive investments. During periods of interest rate volatility, these investments may not provide attractive returns. Investments in securities of an MLP also include tax-related risks. For example, to the extent a distribution received by the Fund from an MLP is treated as a return of capital, the Fund’s adjusted tax basis in the interests of the MLP may be reduced, which will result in an increase in an amount of income or gain (or decrease in the amount of loss) that will be recognized by the Fund for tax purposes upon the sale of any such interests or upon subsequent distributions in respect of such interests. Option Writing Risk.  Writing (selling) call options limits the opportunity to profit from an increase in the market value of stocks in exchange for up-front cash (the premium) at the time of selling the call option. In a rising market, the Fund could significantly underperform the market. Furthermore, the Fund’s call option writing strategies may not fully protect it against market declines because the Fund will continue to bear the risk of a decline in the value of its portfolio securities. In a sharply-falling equity market, the Fund will likely also experience sharp declines in its net asset value (“NAV”). REIT Risk.  Risks associated with investments such as REITs in the real estate industry include, among others: possible declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage financing, variations in rental income, neighborhood values or the appeal of property to tenants; interest rates; overbuilding; extended vacancies of properties; increases in competition, property taxes and operating expenses; and changes in zoning laws. REITs whose underlying properties are concentrated in a particular industry or geographic region are subject to risks affecting such industries and regions. The securities of REITs involve greater risks than those associated with larger, more established companies and may be subject to more abrupt or erratic price movements because of interest rate changes, economic conditions and other factors. Securities of such issuers may lack sufficient market liquidity to enable the Fund to effect sales at an advantageous time or without a substantial drop in price. Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund’s Class A Shares from year to year; and (b) how the average annual total returns of the Fund’s Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and Class T Shares compare to those of a broad-based securities market index. Prior to June 20, 2017, the Fund had been known as the Goldman Sachs Growth and Income Fund, and certain of its principal investment strategies differed. Performance information set forth below prior to June 20, 2017 reflects the performance resulting from the Fund’s former strategies. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus. The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[2] The Fund’s “Management Fees” have been restated to reflect current fees.

[3] The “Other Expenses” for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[4] The Investment Adviser has agreed to reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, shareholder administration fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% of the Fund’s average daily net assets. This arrangement will remain in effect through at least December 29, 2018, and prior to such date the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees.

[5] After Expense Limitation

[6] Class R6 Shares commenced operations on July 31, 2015.

Expense Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in Class A, Class C, Institutional, Investor, Class R, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Investor, Class R, Class R6 and/or Class T Shares at the end of those periods, unless otherwise stated. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same (except that the Example incorporates the fee waiver and expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Assumingno redemption

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
Goldman Sachs Focused Value Fund | Class C Shares | USD ($)	190	1,880	3,455	6,935

Portfolio Turnover

The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended August 31, 2017 was 126% of the average value of its portfolio.

Principal Strategy

The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at time of purchase) ("Net Assets") in a portfolio of equity investments, including common stocks, preferred stocks, and other securities and instruments having equity characteristics. The Fund seeks to achieve its investment objective by investing, under normal circumstances, in approximately 20-35 companies that are considered value opportunities, which the Investment Adviser defines as companies with identifiable competitive advantages whose intrinsic value is not reflected in the stock price. The Fund may invest in securities of companies of any capitalization. Although the Fund will invest primarily in publicly traded U.S. securities, it may invest up to 20% of its total assets in foreign securities, including securities of issuers in countries with emerging markets or economies ("emerging countries") and securities quoted in foreign currencies.

The Fund's equity investment process involves: (1) using multiple industry-specific valuation metrics to identify real economic value and company potential in stocks, screened by valuation, profitability and business characteristics; (2) conducting in-depth company research and assessing overall business quality; and (3) buying those securities that a sector portfolio manager recommends, taking into account feedback from the rest of the portfolio management team. The Investment Adviser may decide to sell a position for various reasons, including valuation and price considerations, readjustment of the Investment Adviser's outlook based on subsequent events, the Investment Adviser's ongoing assessment of the quality and effectiveness of management, if new investment ideas offer the potential for better risk/reward profiles than existing holdings, or for risk management purposes. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions.

The Fund may invest in fixed income securities, such as government, corporate and bank debt obligations.

The Fund's benchmark index is the Russell 1000^® Value Index.

THE FUND IS "NON-DIVERSIFIED" UNDER THE INVESTMENT COMPANY ACT OF 1940, AS AMENDED (THE "INVESTMENT COMPANY ACT"), AND MAY INVEST A LARGER PERCENTAGE OF ITS ASSETS IN FEWER ISSUERS THAN DIVERSIFIED MUTUAL FUNDS.

Principal Risks of the Fund

Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing.

Foreign and Emerging Countries Risk.  Foreign securities may be subject to risk of loss because of more or less foreign government regulation, less public information and less economic, political and social stability in the countries in which the Fund invests. The imposition of exchange controls, sanctions, confiscations, trade restrictions (including tariffs) and other government restrictions by the United States and other governments, or from problems in share registration, settlement or custody, may also result in losses. Foreign risk also involves the risk of negative foreign currency rate fluctuations, which may cause the value of securities denominated in such foreign currency (or other instruments through which the Fund has exposure to foreign currencies) to decline in value. Currency exchange rates may fluctuate significantly over short periods of time. These risks may be more pronounced in connection with the Fund's investments in securities of issuers located in emerging countries.

Investment Style Risk.  Different investment styles (e.g., "growth," "value" or "quantitative") tend to shift in and out of favor depending upon market and economic conditions as well as investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles. Value investing is an example of an investment style. Value stocks are those believed to be undervalued in comparison to their peers, due to market, company-specific or other factors.

Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s net asset value (“NAV”) and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio.

Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.

Mid-Cap and Small-Cap Risk.  Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks.

Non-Diversification Risk.  The Fund is non-diversified, meaning that it is permitted to invest a larger percentage of its assets in fewer issuers than diversified mutual funds. Thus, the Fund may be more susceptible to adverse developments affecting any single issuer held in its portfolio, and may be more susceptible to greater losses because of these developments. Under normal circumstances, the Fund intends to invest in approximately 20-35 companies.

Portfolio Turnover Rate Risk.  A high rate of portfolio turnover (100% or more) involves correspondingly greater expenses which must be borne by the Fund and its shareholders, and is also likely to result in short-term capital gains taxable to shareholders.

Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

Performance

The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund's Class A Shares from year to year; and (b) how the average annual total returns of the Fund's Class A, Class C, Institutional, Investor, Class R, Class R6 and Class T Shares compare to those of a broad-based securities market index. The Fund's past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus.

The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

The after-tax returns are for Class A Shares only. The after-tax returns for Class C, Institutional, Investor, Class R6 and Class T Shares, and returns for Class R Shares (which are offered exclusively to employee benefit plans), will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[1] The Fund’s “Management Fees” have been restated to reflect current fees.

[2] The “Other Expenses” for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[3] The Investment Adviser has agreed to reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% of the Fund’s average daily net assets. This arrangement will remain in effect through at least December 29, 2018, and prior to such date, the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees.

[4] After Expense Limitation

[1] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares' inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[2] The Fund’s “Management Fees” have been restated to reflect current fees.

[3] The “Other Expenses” for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[4] The Investment Adviser has agreed to reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% of the Fund’s average daily net assets. This arrangement will remain in effect through at least December 29, 2018, and prior to such date, the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees.

[5] After Expense Limitation

[6] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares' inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

Expense Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares at the end of those periods, unless otherwise stated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the fee waiver and expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Assuming complete redemption at end of period

Expense Example - Goldman Sachs Large Cap Value Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A Shares	656	903	1,168	1,926
Class C Shares	288	605	1,047	2,276
Institutional Shares	80	258	451	1,010
Service Shares	130	414	720	1,587
Investor Shares	87	295	520	1,168
Class R Shares	137	451	787	1,737
Class R6 Shares	79	255	446	998
Class T Shares	359	614	888	1,670

Assuming no redemption

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
Goldman Sachs Large Cap Value Fund | Class C Shares | USD ($)	188	605	1,047	2,276

Portfolio Turnover

The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended August 31, 2017 was 124% of the average value of its portfolio.

Principal Strategy

The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at time of purchase) (“Net Assets”) in a diversified portfolio of equity investments in large-cap U.S. issuers with public stock market capitalizations within the range of the market capitalization of companies constituting the Russell 1000® Value Index at the time of investment. As of September 30, 2017, the capitalization range of the Russell 1000® Value Index was between $1.6 billion and $452.3 billion. Although the Fund will invest primarily in publicly traded U.S. securities, it may invest in foreign securities, including securities of issuers in countries with emerging markets or economies (“emerging countries”) and securities quoted in foreign currencies.

The Fund seeks its investment objective by investing in value opportunities that the Investment Adviser defines as companies with identifiable competitive advantages whose intrinsic value is not reflected in the stock price. The Fund’s equity investment process involves: (1) using multiple industry-specific valuation metrics to identify real economic value and company potential in stocks, screened by valuation, profitability and business characteristics; (2) conducting in-depth company research and assessing overall business quality; and (3) buying those securities that a sector portfolio manager recommends, taking into account feedback from the rest of the portfolio management team. The Investment Adviser may decide to sell a position for various reasons, including valuation and price considerations, readjustment of the Investment Adviser’s outlook based on subsequent events, the Investment Adviser’s ongoing assessment of the quality and effectiveness of management, if new investment ideas offer the potential for better risk/reward profiles than existing holdings, or for risk management purposes. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions.

The Fund may also invest in companies with public stock market capitalizations outside the range of companies constituting the Russell 1000^® Value Index at the time of investment and in fixed income securities, such as government, corporate and bank debt obligations.

The Fund’s benchmark index is the Russell 1000^® Value Index.

Principal Risks of the Fund

Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing.

Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles. Value stocks are those believed to be undervalued in comparison to their peers, due to market, company-specific or other factors.

Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio.

Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.

Portfolio Turnover Rate Risk.  A high rate of portfolio turnover (100% or more) involves correspondingly greater expenses which must be borne by the Fund and its shareholders, and is also likely to result in short-term capital gains taxable to shareholders.

Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

Performance

The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund’s Class A Shares from year to year; and (b) how the average annual total returns of the Fund’s Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and Class T Shares compare to those of a broad-based securities market index. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus.

The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

The after-tax returns are for Class A Shares only. The after-tax returns for Class C, Institutional, Service, Investor, Class R6 and Class T Shares, and returns for Class R Shares (which are offered exclusively to employee benefit plans), will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] A contingent deferred sales charge ("CDSC") of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[1] The "Other Expenses" for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[2] The Investment Adviser has agreed to reduce or limit "Other Expenses" (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, shareholder administration fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% of the Fund's average daily net assets. Additionally, Goldman Sachs & Co. ("Goldman Sachs"), the Fund's transfer agent, has agreed to waive a portion of its transfer agency fee (a component of "Other Expenses") equal to 0.07% as an annual percentage rate of the average daily net assets attributable to Class A, Class C, Investor, Class R and Class T Shares of the Fund. These arrangements will remain in effect through at least December 29, 2018, and prior to such date, the Investment Adviser and Goldman Sachs may not terminate the arrangements without the approval of the Board of Trustees.

[3] After Fee Waiver and Expense Limitation

[1] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares' inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[2] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares’ inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

You may qualify for sales charge discounts on purchases of Class A or Class T Shares if you invest at least $50,000 or $250,000, respectively, in Goldman Sachs Funds. More information about these and other discounts is available from your financial professional and in “Shareholder Guide—Common Questions Applicable to the Purchase of Class A Shares” beginning on page 56 and “Shareholder Guide—Common Questions Applicable to the Purchase of Class T Shares” beginning on page 59 and in Appendix D—Additional Information About Sales Charge Variations, Waivers and Discounts on page 102 of the Prospectus and “Other Information Regarding Maximum Sales Charge, Purchases, Redemptions, Exchanges and Dividends” beginning on page B-106 of the Fund’s Statement of Additional Information (“SAI”).

Portfolio Turnover [Text Block]	rr_PortfolioTurnoverTextBlock	The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended August 31, 2017 was 124% of the average value of its portfolio.

Expense Example [Heading]	rr_ExpenseExampleHeading	Expense Example
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares at the end of those periods, unless otherwise stated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the fee waiver and expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Expense Example, No Redemption, By Year, Caption [Text]	rr_ExpenseExampleNoRedemptionByYearCaption	Assuming no redemption
Strategy [Heading]	rr_StrategyHeading	Principal Strategy
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at time of purchase) (“Net Assets”) in a diversified portfolio of equity investments in large-cap U.S. issuers with public stock market capitalizations within the range of the market capitalization of companies constituting the Russell 1000® Value Index at the time of investment. As of September 30, 2017, the capitalization range of the Russell 1000® Value Index was between $1.6 billion and $452.3 billion. Although the Fund will invest primarily in publicly traded U.S. securities, it may invest in foreign securities, including securities of issuers in countries with emerging markets or economies (“emerging countries”) and securities quoted in foreign currencies. The Fund seeks its investment objective by investing in value opportunities that the Investment Adviser defines as companies with identifiable competitive advantages whose intrinsic value is not reflected in the stock price. The Fund’s equity investment process involves: (1) using multiple industry-specific valuation metrics to identify real economic value and company potential in stocks, screened by valuation, profitability and business characteristics; (2) conducting in-depth company research and assessing overall business quality; and (3) buying those securities that a sector portfolio manager recommends, taking into account feedback from the rest of the portfolio management team. The Investment Adviser may decide to sell a position for various reasons, including valuation and price considerations, readjustment of the Investment Adviser’s outlook based on subsequent events, the Investment Adviser’s ongoing assessment of the quality and effectiveness of management, if new investment ideas offer the potential for better risk/reward profiles than existing holdings, or for risk management purposes. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions. The Fund may also invest in companies with public stock market capitalizations outside the range of companies constituting the Russell 1000® Value Index at the time of investment and in fixed income securities, such as government, corporate and bank debt obligations. The Fund’s benchmark index is the Russell 1000® Value Index.
Risk [Heading]	rr_RiskHeading	Principal Risks of the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing. Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles. Value stocks are those believed to be undervalued in comparison to their peers, due to market, company-specific or other factors. Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio. Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets. Portfolio Turnover Rate Risk.  A high rate of portfolio turnover (100% or more) involves correspondingly greater expenses which must be borne by the Fund and its shareholders, and is also likely to result in short-term capital gains taxable to shareholders. Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

Risk Not Insured Depository Institution [Text]	rr_RiskNotInsuredDepositoryInstitution	An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency.
Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	Performance
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund’s Class A Shares from year to year; and (b) how the average annual total returns of the Fund’s Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and Class T Shares compare to those of a broad-based securities market index. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus. The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

[1] A contingent deferred sales charge ("CDSC") of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[2] The "Other Expenses" for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[3] The Investment Adviser has agreed to reduce or limit "Other Expenses" (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, shareholder administration fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% of the Fund's average daily net assets. Additionally, Goldman Sachs & Co. ("Goldman Sachs"), the Fund's transfer agent, has agreed to waive a portion of its transfer agency fee (a component of "Other Expenses") equal to 0.07% as an annual percentage rate of the average daily net assets attributable to Class A, Class C, Investor, Class R and Class T Shares of the Fund. These arrangements will remain in effect through at least December 29, 2018, and prior to such date, the Investment Adviser and Goldman Sachs may not terminate the arrangements without the approval of the Board of Trustees.

[4] After Fee Waiver and Expense Limitation

[5] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares' inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[6] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares’ inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

Expense Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares at the end of those periods, unless otherwise stated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the fee waiver and expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Assuming complete redemption at end of period

Expense Example - Goldman Sachs Mid Cap Value Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A Shares	662	898	1,153	1,881
Class C Shares	294	600	1,032	2,233
Institutional Shares	79	246	428	954
Service Shares	129	403	697	1,534
Investor Shares	93	290	504	1,120
Class R Shares	144	446	771	1,691
Class R6 Shares	78	243	422	942
Class T Shares	365	609	872	1,624

Assuming no redemption

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
Goldman Sachs Mid Cap Value Fund | Class C Shares | USD ($)	194	600	1,032	2,233

Portfolio Turnover

The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended August 31, 2017 was 124% of the average value of its portfolio.

Principal Strategy

The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at time of purchase) (“Net Assets”) in a diversified portfolio of equity investments in mid-cap issuers with public stock market capitalizations within the range of the market capitalization of companies constituting the Russell Midcap^® Value Index at the time of investment. As of September 30, 2017, the capitalization range of the Russell Midcap^® Value Index was between $1.6 billion and $33.8 billion. Although the Fund will invest primarily in publicly traded U.S. securities, including real estate investment trusts (“REITs”), it may invest in foreign securities, including securities of issuers in countries with emerging markets or economies (“emerging countries”) and securities quoted in foreign currencies.

The Fund’s equity investment process involves: (1) using multiple industry-specific valuation metrics to identify real economic value and company potential in stocks, screened by valuation, profitability and business characteristics; (2) conducting in-depth company research and assessing overall business quality; and (3) buying those securities that a sector portfolio manager recommends, taking into account feedback from the rest of the portfolio management team. The Investment Adviser may decide to sell a position for various reasons, including valuation and price considerations, readjustment of the Investment Adviser’s outlook based on subsequent events, the Investment Adviser’s ongoing assessment of the quality and effectiveness of management, if new investment ideas offer the potential for better risk/reward profiles than existing holdings, or for risk management purposes. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions.

The Fund may also invest in companies with public stock market capitalizations outside the range of companies constituting the Russell Midcap^® Value Index at the time of investment and in fixed income securities, such as government, corporate and bank debt obligations.

The Fund’s benchmark index is the Russell Midcap^® Value Index.

Principal Risks of the Fund

Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing.

Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles. Value stocks are those believed to be undervalued in comparison to their peers, due to market, company-specific or other factors.

Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio.

Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.

Mid-Cap and Small-Cap Risk.  Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks.

Portfolio Turnover Rate Risk.  A high rate of portfolio turnover (100% or more) involves correspondingly greater expenses which must be borne by the Fund and its shareholders, and is also likely to result in short-term capital gains taxable to shareholders.

REIT Risk.  Risks associated with investments such as REITs in the real estate industry include, among others: possible declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage financing, variations in rental income, neighborhood values or the appeal of property to tenants; interest rates; overbuilding; extended vacancies of properties; increases in competition, property taxes and operating expenses; and changes in zoning laws. REITs whose underlying properties are concentrated in a particular industry or geographic region are subject to risks affecting such industries and regions. The securities of REITs involve greater risks than those associated with larger, more established companies and may be subject to more abrupt or erratic price movements because of interest rate changes, economic conditions and other factors. Securities of such issuers may lack sufficient market liquidity to enable the Fund to effect sales at an advantageous time or without a substantial drop in price.

Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

Performance

The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund’s Class A Shares from year to year; and (b) how the average annual total returns of the Fund’s Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and Class T Shares compare to those of a broad-based securities market index. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus.

The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

The after-tax returns are for Class A Shares only. The after-tax returns for Class C, Institutional, Service, Investor, Class R6 and Class T Shares, and returns for Class R Shares (which are offered exclusively to employee benefit plans), will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[1] The “Other Expenses” for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[1] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares' inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[2] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares' inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended August 31, 2017 was 124% of the average value of its portfolio.
Portfolio Turnover, Rate	rr_PortfolioTurnoverRate	124.00%
Expenses Deferred Charges [Text Block]	rr_ExpensesDeferredChargesTextBlock	A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.
Expense Breakpoint Discounts [Text]	rr_ExpenseBreakpointDiscounts	You may qualify for sales charge discounts on purchases of Class A or Class T Shares if you invest at least $50,000 or $250,000, respectively, in Goldman Sachs Funds. More information about these and other discounts is available from your financial professional and in “Shareholder Guide—Common Questions Applicable to the Purchase of Class A Shares” beginning on page 56 and “Shareholder Guide—Common Questions Applicable to the Purchase of Class T Shares” beginning on page 59 and in Appendix D—Additional Information About Sales Charge Variations, Waivers and Discounts on page 102 of the Prospectus and “Other Information Regarding Maximum Sales Charge, Purchases, Redemptions, Exchanges and Dividends” beginning on page B-106 of the Fund’s Statement of Additional Information (“SAI”).
Other Expenses, New Fund, Based on Estimates [Text]	rr_OtherExpensesNewFundBasedOnEstimates	The “Other Expenses” for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.
Expense Example [Heading]	rr_ExpenseExampleHeading	Expense Example
Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares at the end of those periods, unless otherwise stated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the fee waiver and expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]	rr_StrategyHeading	Principal Strategy
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at time of purchase) (“Net Assets”) in a diversified portfolio of equity investments in mid-cap issuers with public stock market capitalizations within the range of the market capitalization of companies constituting the Russell Midcap® Value Index at the time of investment. As of September 30, 2017, the capitalization range of the Russell Midcap® Value Index was between $1.6 billion and $33.8 billion. Although the Fund will invest primarily in publicly traded U.S. securities, including real estate investment trusts (“REITs”), it may invest in foreign securities, including securities of issuers in countries with emerging markets or economies (“emerging countries”) and securities quoted in foreign currencies. The Fund’s equity investment process involves: (1) using multiple industry-specific valuation metrics to identify real economic value and company potential in stocks, screened by valuation, profitability and business characteristics; (2) conducting in-depth company research and assessing overall business quality; and (3) buying those securities that a sector portfolio manager recommends, taking into account feedback from the rest of the portfolio management team. The Investment Adviser may decide to sell a position for various reasons, including valuation and price considerations, readjustment of the Investment Adviser’s outlook based on subsequent events, the Investment Adviser’s ongoing assessment of the quality and effectiveness of management, if new investment ideas offer the potential for better risk/reward profiles than existing holdings, or for risk management purposes. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions. The Fund may also invest in companies with public stock market capitalizations outside the range of companies constituting the Russell Midcap® Value Index at the time of investment and in fixed income securities, such as government, corporate and bank debt obligations. The Fund’s benchmark index is the Russell Midcap® Value Index.
Risk [Heading]	rr_RiskHeading	Principal Risks of the Fund
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing. Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles. Value stocks are those believed to be undervalued in comparison to their peers, due to market, company-specific or other factors. Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio. Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets. Mid-Cap and Small-Cap Risk.  Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks. Portfolio Turnover Rate Risk.  A high rate of portfolio turnover (100% or more) involves correspondingly greater expenses which must be borne by the Fund and its shareholders, and is also likely to result in short-term capital gains taxable to shareholders. REIT Risk.  Risks associated with investments such as REITs in the real estate industry include, among others: possible declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage financing, variations in rental income, neighborhood values or the appeal of property to tenants; interest rates; overbuilding; extended vacancies of properties; increases in competition, property taxes and operating expenses; and changes in zoning laws. REITs whose underlying properties are concentrated in a particular industry or geographic region are subject to risks affecting such industries and regions. The securities of REITs involve greater risks than those associated with larger, more established companies and may be subject to more abrupt or erratic price movements because of interest rate changes, economic conditions and other factors. Securities of such issuers may lack sufficient market liquidity to enable the Fund to effect sales at an advantageous time or without a substantial drop in price. Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

Bar Chart and Performance Table [Heading]	rr_BarChartAndPerformanceTableHeading	Performance
Performance Narrative [Text Block]	rr_PerformanceNarrativeTextBlock	The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund’s Class A Shares from year to year; and (b) how the average annual total returns of the Fund’s Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and Class T Shares compare to those of a broad-based securities market index. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus. The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

Expense Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and/or Class T Shares at the end of those periods, unless otherwise stated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the fee waiver and expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Assuming complete redemption at end of period

Expense Example - Goldman Sachs Small Cap Value Fund - USD ($)	1 Year	3 Years	5 Years	10 Years
Class A Shares	679	955	1,252	2,093
Class C Shares	312	659	1,132	2,440
Institutional Shares	97	307	534	1,188
Service Shares	148	463	801	1,756
Investor Shares	111	351	610	1,350
Class R Shares	162	506	874	1,909
Class R6 Shares	96	304	529	1,176
Class T Shares	383	668	974	1,842

Assuming no redemption

Expense Example, No Redemption	1 Year	3 Years	5 Years	10 Years
Goldman Sachs Small Cap Value Fund | Class C Shares | USD ($)	212	659	1,132	2,440

Portfolio Turnover

The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended August 31, 2017 was 68% of the average value of its portfolio.

Principal Strategy

The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at time of purchase) (“Net Assets”) in a diversified portfolio of equity investments in small-cap issuers with public stock market capitalizations within the range of the market capitalization of companies constituting the Russell 2000® Value Index at the time of investment. As of September 30, 2017, the capitalization range of the Russell 2000® Value Index was between $25.8 million and $9.4 billion. Under normal circumstances, the Fund’s investment horizon for ownership of stocks will be two to three years. Although the Fund will invest primarily in publicly traded U.S. securities, including real estate investment trusts (“REITs”), it may also invest in foreign securities, including securities of issuers in countries with emerging markets or economies (“emerging countries”) and securities quoted in foreign currencies.

The Fund’s equity investment process involves: (1) using multiple industry-specific valuation metrics to identify real economic value and company potential in stocks, screened by valuation, profitability and business characteristics; (2) conducting in-depth company research and assessing overall business quality; and (3) buying those securities that a sector portfolio manager recommends, taking into account feedback from the rest of the portfolio management team. The Investment Adviser may decide to sell a position for various reasons, including valuation and price considerations, readjustment of the Investment Adviser’s outlook based on subsequent events, the Investment Adviser’s ongoing assessment of the quality and effectiveness of management, if new investment ideas offer the potential for better risk/reward profiles than existing holdings, or for risk management purposes. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions.

The Fund may invest in companies with public stock market capitalizations outside the range of companies constituting the Russell 2000® Value Index at the time of investment and in fixed income securities, such as government, corporate and bank debt obligations.

The Fund’s benchmark index is the Russell 2000^® Value Index.

Principal Risks of the Fund

Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing.

Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles. Value stocks are those believed to be undervalued in comparison to their peers, due to market, company-specific or other factors.

Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio.

Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.

Mid-Cap and Small-Cap Risk.  Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks.

REIT Risk.  Risks associated with investments such as REITs in the real estate industry include, among others: possible declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage financing, variations in rental income, neighborhood values or the appeal of property to tenants; interest rates; overbuilding; extended vacancies of properties; increases in competition, property taxes and operating expenses; and changes in zoning laws. REITs whose underlying properties are concentrated in a particular industry or geographic region are subject to risks affecting such industries and regions. The securities of REITs involve greater risks than those associated with larger, more established companies and may be subject to more abrupt or erratic price movements because of interest rate changes, economic conditions and other factors. Securities of such issuers may lack sufficient market liquidity to enable the Fund to effect sales at an advantageous time or without a substantial drop in price.

Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

Performance

The bar chart and table below provide an indication of the risks of investing in the Fund by showing: (a) changes in the performance of the Fund’s Class A Shares from year to year; and (b) how the average annual total returns of the Fund’s Class A, Class C, Institutional, Service, Investor, Class R, Class R6 and Class T Shares compare to those of a broad-based securities market index. The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus.

The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less. Performance reflects applicable fee waivers and/or expense limitations in effect during the periods shown.

The after-tax returns are for Class A Shares only. The after-tax returns for Class C, Institutional, Service, Investor, Class R6 and Class T Shares, and returns for Class R Shares (which are offered exclusively to employee benefit plans), will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[1] The Fund’s “Management Fees” have been restated to reflect current expenses.

[2] The “Other Expenses” for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[3] The Investment Adviser has agreed to reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, shareholder administration fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% of the Fund’s average daily net assets. This arrangement will remain in effect through at least December 29, 2018, and prior to such date the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees.

[4] After Expense Limitation

[1] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares' inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[2] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares’ inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

The Fund’s past performance, before and after taxes, is not necessarily an indication of how the Fund will perform in the future. Updated performance information is available at no cost at www.gsamfunds.com/performance or by calling the appropriate phone number on the back cover of the Prospectus. The bar chart (including “Best Quarter” and “Worst Quarter” information) does not reflect the sales loads applicable to Class A Shares. If the sales loads were reflected, returns would be less.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[2] The Fund’s “Management Fees” have been restated to reflect current expenses.

[3] The “Other Expenses” for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[4] The Investment Adviser has agreed to reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, shareholder administration fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% of the Fund’s average daily net assets. This arrangement will remain in effect through at least December 29, 2018, and prior to such date the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees.

[5] After Expense Limitation

[6] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares' inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[7] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares’ inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

Expense Example

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

This Example assumes that you invest $10,000 in Class A, Class C, Institutional, Investor, Class R, Class R6 and/or Class T Shares of the Fund for the time periods indicated and then redeem all of your Class A, Class C, Institutional, Investor, Class R, Class R6 and/or Class T Shares at the end of those periods, unless otherwise stated. The Example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same (except that the Example incorporates the fee waiver and expense limitation arrangements for only the first year). Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Assuming complete redemption at end of period

Portfolio Turnover

The Fund pays transaction costs when it buys and sells securities or instruments (i.e., “turns over” its portfolio). A high rate of portfolio turnover may result in increased transaction costs, including brokerage commissions, which must be borne by the Fund and its shareholders, and is also likely to result in higher short-term capital gains for taxable shareholders. These costs are not reflected in the annual fund operating expenses or in the expense example above, but are reflected in the Fund’s performance. The Fund’s portfolio turnover rate for the fiscal year ended August 31, 2017 was 108% of the average value of its portfolio.

Principal Strategy

The Fund invests, under normal circumstances, at least 80% of its net assets plus any borrowings for investment purposes (measured at time of purchase) (“Net Assets”) in a diversified portfolio of equity investments in small- and mid-cap issuers with public stock market capitalizations within the range of the market capitalization of companies constituting the Russell 2000^® Value Index and the Russell Midcap^® Value Index, respectively, at the time of investment. As of September 30, 2017, the capitalization range of the companies in these indices was between $25.8 million and $33.8 billion. Under normal circumstances, the Fund’s investment horizon for ownership of stocks will be two to three years. Although the Fund will invest primarily in publicly traded U.S. securities, including real estate investment trusts (“REITs”), it may also invest in foreign securities, including securities of issuers in countries with emerging markets or economies (“emerging countries”) and securities quoted in foreign currencies.

The Fund’s equity investment process involves: (1) using multiple industry-specific valuation metrics to identify real economic value and company potential in stocks, screened by valuation, profitability and business characteristics; (2) conducting in-depth company research and assessing overall business quality; and (3) buying those securities that a sector portfolio manager recommends, taking into account feedback from the rest of the portfolio management team. The Investment Adviser may decide to sell a position for various reasons, including valuation and price considerations, readjustment of the Investment Adviser’s outlook based on subsequent events, the Investment Adviser’s ongoing assessment of the quality and effectiveness of management, if new investment ideas offer the potential for better risk/reward profiles than existing holdings, or for risk management purposes. In addition, the Investment Adviser may sell a position in order to meet shareholder redemptions.

The Fund may invest in companies with public stock market capitalizations outside the range of companies constituting the Russell 2000^® Value Index and the Russell Midcap^® Value Index at the time of investment and in fixed income securities, such as government, corporate and bank debt obligations.

The Fund’s benchmark index is the Russell 2500^® Value Index.

Principal Risks of the Fund

Loss of money is a risk of investing in the Fund. An investment in the Fund is not a bank deposit and is not insured or guaranteed by the Federal Deposit Insurance Corporation (“FDIC”) or any government agency. The Fund should not be relied upon as a complete investment program. There can be no assurance that the Fund will achieve its investment objective. Investments in the Fund involve substantial risks which prospective investors should consider carefully before investing.

Investment Style Risk.  Different investment styles (e.g., “growth”, “value” or “quantitative”) tend to shift in and out of favor depending upon market and economic conditions and investor sentiment. The Fund may outperform or underperform other funds that invest in similar asset classes but employ different investment styles. Value stocks are those believed to be undervalued in comparison to their peers, due to market, company-specific or other factors.

Large Shareholder Transactions Risk.  The Fund may experience adverse effects when certain large shareholders purchase or redeem large amounts of shares of the Fund. Such large shareholder redemptions may cause the Fund to sell portfolio securities at times when it would not otherwise do so, which may negatively impact the Fund’s NAV and liquidity. Similarly, large Fund share purchases may adversely affect the Fund’s performance to the extent that the Fund is delayed in investing new cash and is required to maintain a larger cash position than it ordinarily would. These transactions may also accelerate the realization of taxable income to shareholders if such sales of investments resulted in gains, and may also increase transaction costs. In addition, a large redemption could result in the Fund’s current expenses being allocated over a smaller asset base, leading to an increase in the Fund’s expense ratio.

Market Risk.  The value of the securities in which the Fund invests may go up or down in response to the prospects of individual companies, particular sectors or governments and/or general economic conditions throughout the world due to increasingly interconnected global economies and financial markets.

Mid-Cap and Small-Cap Risk.  Investments in mid-capitalization and small-capitalization companies involve greater risks than those associated with larger, more established companies. These securities may be subject to more abrupt or erratic price movements and may lack sufficient market liquidity, and these issuers often face greater business risks.

Portfolio Turnover Rate Risk.  A high rate of portfolio turnover (100% or more) involves correspondingly greater expenses which must be borne by the Fund and its shareholders, and is also likely to result in short-term capital gains taxable to shareholders.

REIT Risk.  Risks associated with investments such as REITs in the real estate industry include, among others: possible declines in the value of real estate; risks related to general and local economic conditions; possible lack of availability of mortgage financing, variations in rental income, neighborhood values or the appeal of property to tenants; interest rates; overbuilding; extended vacancies of properties; increases in competition, property taxes and operating expenses; and changes in zoning laws. REITs whose underlying properties are concentrated in a particular industry or geographic region are subject to risks affecting such industries and regions. The securities of REITs involve greater risks than those associated with larger, more established companies and may be subject to more abrupt or erratic price movements because of interest rate changes, economic conditions and other factors. Securities of such issuers may lack sufficient market liquidity to enable the Fund to effect sales at an advantageous time or without a substantial drop in price.

Stock Risk.  Stock prices have historically risen and fallen in periodic cycles. U.S. and foreign stock markets have experienced periods of substantial price volatility in the past and may do so again in the future.

The after-tax returns are for Class A Shares only. The after-tax returns for Class C, Institutional, Investor, Class R6 and Class T Shares, and returns for Class R Shares (which are offered exclusively to employee benefit plans), will vary. After-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor’s tax situation and may differ from those shown. In addition, the after-tax returns shown are not relevant to investors who hold Fund shares through tax-deferred arrangements such as 401(k) plans or individual retirement accounts.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[1] The Fund’s “Management Fees” have been restated to reflect current fees.

[2] The “Other Expenses” for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[3] The Investment Adviser has agreed to reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% of the Fund’s average daily net assets. This arrangement will remain in effect through at least December 29, 2018, and prior to such date, the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees.

[4] After Expense Limitation

[1] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares’ inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[2] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares' inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.

[1] A contingent deferred sales charge (“CDSC”) of 1% is imposed on Class C Shares redeemed within 12 months of purchase.

[2] The Fund’s “Management Fees” have been restated to reflect current fees.

[3] The “Other Expenses” for Class T Shares have been estimated to reflect expenses expected to be incurred during the current fiscal year.

[4] The Investment Adviser has agreed to reduce or limit “Other Expenses” (excluding acquired fund fees and expenses, transfer agency fees and expenses, service fees, taxes, interest, brokerage fees, expenses of shareholder meetings, litigation and indemnification, and extraordinary expenses) to 0.004% of the Fund’s average daily net assets. This arrangement will remain in effect through at least December 29, 2018, and prior to such date, the Investment Adviser may not terminate the arrangement without the approval of the Board of Trustees.

[5] After Expense Limitation

[6] Class R6 Shares commenced operations on July 31, 2015. Prior to that date, the performance of the Class R6 Shares shown in the table above is that of the Institutional Shares, including since inception performance as of Institutional Shares’ inception date. Performance has not been adjusted to reflect the lower expenses of Class R6 Shares. Class R6 Shares would have had higher returns because: (i) Institutional Shares and Class R6 Shares represent interests in the same portfolio of securities; and (ii) Class R6 Shares have lower expenses.

[7] As of the date of the Prospectus, Class T Shares have not commenced operations. Performance of Class T Shares shown in the table above is that of Class A Shares, including since inception performance as of Class A Shares' inception date. Performance has not been adjusted to reflect the lower maximum sales charge (load) imposed on purchases of Class T Shares. Class T Shares would have had higher returns because: (i) Class A Shares and Class T Shares represent interests in the same portfolio of securities; and (ii) Class T Shares impose a lower maximum sales charge (load) on purchases.
