Expense Narrative [Text Block] rr_ExpenseNarrativeTextBlock This table describes the fees and expenses that you may pay if you buy, hold, and sell shares of the fund. The fees and expenses set forth below are annualized based on the fees and expenses for the six-month period ended November 30, 2019. You may also incur brokerage commissions and other charges when buying or selling shares of the Investor Class or I Class, which are not reflected in the table.

Portfolio Turnover [Heading] rr_PortfolioTurnoverHeading Portfolio Turnover
Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when the fund’s shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s performance. During the most recent 6-month period ended November 30, 2019, the fund’s portfolio turnover rate was 112.9% of the average value of its portfolio.

Expenses Not Correlated to Ratio Due to Acquired Fund Fees [Text] rr_ExpensesNotCorrelatedToRatioDueToAcquiredFundFees The figures shown in the fee table do not match the “Net expenses after waivers/payments by Price Associates” shown in the Financial Highlights table, as those figures do not include acquired fund fees and expenses and exclude expenses permanently waived as a result of investments in other T. Rowe Price Funds. The figures shown in the fee table do not match the “Gross expenses before waivers/payments by Price Associates” shown in the Financial Highlights table, as those figures reflect the effects of a management fee waiver agreement, do not include acquired fund fees and expenses, and exclude expenses permanently waived as a result of investments in other T.

Expense Example [Heading] rr_ExpenseExampleHeading 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. The example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods, that your investment has a 5% return each year, and that the fund’s operating expenses remain the same. The example also assumes that any current expense limitation arrangement remains in place for the period noted in the table above; therefore, the figures have been adjusted to reflect fee waivers or expense reimbursements only in the periods for which the expense limitation arrangement is expected to continue. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading] rr_StrategyHeading Investments, Risks, and Performance Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock The fund will invest at least 80% of its net assets in income-producing securities, which may include, but are not limited to, U.S. government and agency obligations, mortgage- and asset-backed securities (including commercial mortgage-backed securities), corporate bonds, foreign bonds, and Treasury inflation protected securities.

Active management of the portfolio can result in bonds being sold at gains or losses. However, over the long term, the fund seeks to achieve its objective by investing primarily in income-producing securities that possess what the fund believes are favorable total return (income plus increases in principal value) characteristics.

Eighty percent (80%) of the debt securities purchased by the fund will be rated investment grade (i.e., rated in one of the four highest rating categories) by each of the major credit rating agencies (S&P Global Ratings, Moody’s, and Fitch) that have assigned a rating to the security or, if unrated, deemed to be of investment-grade quality by T. Rowe Price. Up to 15% of the fund’s net assets may be invested in “split-rated securities,” which are securities that have been rated investment grade by at least one rating agency but below investment grade by another rating agency. The fund may invest up to 20% of its net assets in non-U.S. dollar-denominated foreign debt securities (including securities of issuers in emerging markets) and take currency positions to hedge this exposure as well as to capture appreciation from favorable currency changes. In addition, the fund may maintain a net exposure of up to 5% of its net assets in instruments (through direct holdings and derivatives) that have received below investment-grade ratings from each of the rating agencies that have assigned ratings to the instruments or, if unrated, deemed to be below investment-grade quality by T. Rowe Price (including high yield or “junk” bonds).

The fund has considerable flexibility in seeking high income. There are no maturity restrictions so the fund can purchase longer-term bonds, which tend to have higher yields than shorter-term bonds. In addition, when there is a large yield difference between the various quality levels, the fund may move down the credit scale and purchase lower-rated bonds with higher yields. When the difference is small or the outlook warrants, the fund may concentrate investments in higher-rated issues.

The fund may purchase or sell mortgage-backed securities on a delayed delivery or forward commitment basis through the “to-be-announced” (TBA) market. With TBA transactions, the particular securities to be delivered are not identified at the trade date but the delivered securities must meet specified terms and standards. The fund would generally enter into TBA transactions with the intention of taking possession of the underlying mortgage-backed securities. However, in an effort to obtain underlying mortgage securities on more preferable terms or to enhance returns, the fund may extend the settlement by entering into “dollar roll” transactions in which the fund sells mortgage-backed securities and simultaneously agrees to purchase substantially similar securities on a future date.

While most assets will typically be invested in bonds, the fund also uses interest rate futures and forward currency exchange contracts in keeping with its objective(s). Interest rate futures would typically be used to manage the fund’s exposure to interest rate changes or to adjust portfolio duration. Forward currency exchange contracts would be used to gain exposure to certain currencies expected to increase or decrease in value relative to other currencies or to protect the fund’s foreign bond holdings from adverse currency movements relative to the U.S. dollar.

The fund may sell holdings for a variety of reasons, such as to adjust the portfolio’s average maturity, duration, or overall credit quality, or to shift assets into and out of higher- or lower-yielding securities or certain sectors.
Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock As with any fund, there is no guarantee that the fund will achieve its objective(s). The fund’s share price fluctuates, which means you could lose money by investing in the fund. The principal risks of investing in this fund, which may be even greater during periods of market disruption or volatility, are summarized as follows.

Fixed income markets Economic and other market developments can adversely affect the fixed income securities markets. At times, participants in these markets may develop concerns about the ability of certain issuers of debt instruments to make timely principal and interest payments, or they may develop concerns about the ability of financial institutions that make markets in certain debt instruments to facilitate an orderly market. Those concerns could cause increased volatility and reduced liquidity in particular securities or in the overall fixed income markets and the related derivatives markets. A lack of liquidity or other adverse credit market conditions may hamper the fund’s ability to sell the debt instruments in which it invests or to find and purchase suitable debt instruments.

Interest rates The prices of, and the income generated by, debt instruments held by the fund may be affected by changes in interest rates. A rise in interest rates typically causes the price of a fixed rate debt instrument to fall and its yield to rise. Conversely, a decline in interest rates typically causes the price of a fixed rate debt instrument to rise and the yield to fall. Generally, funds with longer weighted average maturities and durations carry greater interest rate risk. In recent years, the U.S. and many global markets have experienced historically low interest rates. Although interest rates have begun to rise and may continue doing so, interest rates may decline in response to ongoing global trade disputes, increasing the exposure of bond funds to the risks associated with declining interest rates.

Derivatives The use of interest rate futures and forward currency exchange contracts exposes the fund to additional volatility in comparison to investing directly in bonds and other debt instruments. These instruments may lack liquidity and be difficult to value, may involve leverage so that small changes produce disproportionate losses for the fund and, if not traded on an exchange, are subject to the risk that a counterparty to the transaction will fail to meet its obligations under the derivatives contract. The fund’s principal use of derivatives involves the risk that anticipated changes in interest rates or currency values will not be accurately predicted, which could significantly harm the fund’s performance, and the risk that regulatory developments could negatively affect the fund’s investments in such instruments. Changes in regulations could significantly impact the fund’s ability to invest in specific types of derivatives, which could limit the fund’s ability to employ certain strategies that use derivatives.

Sector exposure At times, the fund may have a significant portion of its assets invested in securities of issuers conducting business in a broadly related group of industries within the same economic sector. Issuers in the same economic sector may be similarly affected by economic or market events, making the fund more vulnerable to unfavorable developments in that economic sector than funds that invest more broadly.

Foreign investing Investments in the securities of non-U.S. issuers may be adversely affected by local, political, social, and economic conditions overseas, greater volatility, reduced liquidity, or decreases in foreign currency values relative to the U.S. dollar. The risks of investing outside the U.S. are heightened for any investments in emerging markets, which are susceptible to greater volatility than investments in developed markets.

TBAs and dollar rolls Although the securities that are delivered in TBA transactions must meet certain standards, there is a risk that the actual securities received by the fund may be less favorable than what was anticipated when entering into the transaction. TBA transactions are collateralized but they still involve the risk that a counterparty will fail to deliver the security, exposing the fund to potential losses. Whether or not the fund takes delivery of the securities at the termination date of a TBA transaction, it will nonetheless be exposed to changes in the value of the underlying investments during the term of the agreement. Also, the fund’s portfolio turnover rate and transaction costs are increased when the fund enters into dollar roll transactions.

Credit quality An issuer of a debt instrument could suffer an adverse change in financial condition that results in a payment default (failure to make scheduled interest or principal payments), rating downgrade, or inability to meet a financial obligation. Securities that are rated below investment grade carry greater risk of default and should be considered speculative.

Prepayments and extensions The fund is subject to prepayment risks because the principal on mortgage-backed securities, other asset-backed securities, or any debt instrument with an embedded call option may be prepaid at any time, which could reduce the security’s yield and market value. The rate of prepayments tends to increase as interest rates fall, which could cause the average maturity of the portfolio to shorten. Extension risk may result from a rise in interest rates, which tends to make mortgage-backed securities, asset-backed securities, and other callable debt instruments more volatile.

Liquidity The fund may not be able to meet requests to redeem shares issued by the fund without significant dilution of the remaining shareholders’ interest in the fund. In addition, the fund may not be able to sell a holding in a timely manner at a desired price. Reduced liquidity in the bond markets can result from a number of events, such as limited trading activity, reductions in bond inventory, and rapid or unexpected changes in interest rates. Markets with lower overall liquidity could lead to greater price volatility and limit the fund’s ability to sell a holding at a suitable price.

Portfolio turnover High portfolio turnover may adversely affect the fund’s performance and increase transaction costs, which could increase the fund’s expenses. High portfolio turnover may also result in the distribution of higher capital gains when compared to a fund with less active trading policies, which could have an adverse tax impact if the fund’s shares are held in a taxable account.

Active management The fund’s overall investment program and holdings selected by the fund’s investment adviser may underperform the broad markets, relevant indices, or other funds with similar objectives and investment strategies.

[1] Subject to certain exceptions, accounts with a balance of less than $10,000 are charged an annual $20 fee.
[2] T. Rowe Price Associates, Inc., has contractually agreed (at least through September 30, 2020) to waive a portion of the fund’s management fees so that an individual fund fee of 0.0765% is applied to the fund’s average daily net assets that are equal to or greater than $20 billion. Thereafter, this agreement will automatically renew for one-year terms unless terminated by the fund’s Board of Directors. Any fees waived under this agreement are not subject to reimbursement to T. Rowe Price Associates, Inc., by the fund.
[3] The figures shown in the fee table do not match the “Gross expenses before waivers/payments by Price Associates” shown in the Financial Highlights table, as those figures reflect the effects of a management fee waiver agreement, do not include acquired fund fees and expenses, and exclude expenses permanently waived as a result of investments in other T. Rowe Price Funds (and with respect to the Advisor Class, those figures are also rounded differently).
[4] T. Rowe Price Associates, Inc., is required to permanently waive a portion of its management fee charged to the fund in an amount sufficient to fully offset that portion of management fee paid by each underlying T. Rowe Price Fund related to the fund’s investment therein. The amount of the waiver will vary each fiscal year in proportion to the amount invested in other T. Rowe Price Funds. The T. Rowe Price Funds would be required to seek regulatory approval in order to terminate this arrangement.
[5] The figures shown in the fee table do not match the “Net expenses after waivers/payments by Price Associates” shown in the Financial Highlights table, as those figures do not include acquired fund fees and expenses and exclude expenses permanently waived as a result of investments in other T. Rowe Price Funds.
[6] T. Rowe Price Associates, Inc., has contractually agreed (through September 30, 2020) to waive its fees and/or bear any expenses (excluding interest; expenses related to borrowings, taxes, and brokerage; nonrecurring, extraordinary expenses; and acquired fund fees and expenses) that would cause the class’ ratio of expenses to exceed 1.15% of the class' average daily net assets. The agreement may only be terminated at any time after September 30, 2020, with approval by the fund’s Board of Directors. Fees waived and expenses paid under this agreement (and a previous limitation of 1.15%) are subject to reimbursement to T. Rowe Price Associates, Inc., by the fund whenever the class’ expense ratio is below 1.15%. However, no reimbursement will be made more than three years from the date such amounts were initially waived or reimbursed. The fund may only make repayments to T. Rowe Price Associates, Inc., if such repayment does not cause the class’ expense ratio (after the repayment is taken into account) to exceed the lesser of: (1) the expense limitation in place at the time such amounts were waived; or (2) the class’ current expense limitation.
[7] T. Rowe Price Associates, Inc., has contractually agreed to waive and/or bear all of the Z Class’ expenses (excluding interest; expenses related to borrowings, taxes, and brokerage; nonrecurring, extraordinary expenses; and acquired fund fees and expenses) in their entirety. T. Rowe Price Associates, Inc. expects this fee waiver and/or expense reimbursement arrangement to remain in place indefinitely, and the agreement may only be amended or terminated with approval by the fund’s Board of Directors.
