Business And Summary Of Significant Accounting Policies (Policy)	9 Months Ended
Oct. 31, 2015
Accounting Policies [Abstract]
Nature of Operations [Text Block]	Tech Data Corporation (“Tech Data” or the “Company”) is one of the world’s largest wholesale distributors of technology products. The Company serves as an indispensable link in the technology supply chain by bringing products from the world’s leading technology vendors to market, as well as providing customers with advanced logistics capabilities and value-added services. Tech Data’s customers include value-added resellers, direct marketers, retailers and corporate resellers who support the diverse technology needs of end users. The Company is managed in two geographic segments: the Americas and Europe.
Consolidation, Policy [Policy Text Block]	The consolidated financial statements include the accounts of Tech Data and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The Company operates on a fiscal year that ends on January 31.
Basis of Accounting, Policy [Policy Text Block]	The consolidated financial statements have been prepared by the Company, without audit, pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). The Company prepares its financial statements in conformity with generally accepted accounting principles in the United States (“GAAP”). These principles require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments (consisting of only normal recurring adjustments) necessary to present fairly the consolidated financial position of the Company as of October 31, 2015, its consolidated statements of income and comprehensive income for the three and nine months ended October 31, 2015 and 2014, and its consolidated cash flows for the nine months ended October 31, 2015 and 2014.
Seasonal Fluctuations Policy [Policy Text Block]	The Company’s quarterly operating results have fluctuated significantly in the past and will likely continue to do so in the future as a result of currency fluctuations and seasonal variations in the demand for the products and services offered. Narrow operating margins may magnify the impact of these factors on the Company's operating results. Recent historical seasonal variations have included an increase in European demand during the Company’s fiscal fourth quarter and decreased demand in other fiscal quarters. Given that the majority of the Company’s revenues are derived from Europe, the worldwide results closely follow the seasonality trends in Europe. The seasonal trend in Europe typically results in greater operating leverage, and therefore, lower selling, general and administrative expenses as a percentage of net sales in the region and on a consolidated basis during the second semester of the Company's fiscal year, particularly in the Company's fourth quarter. Additionally, the life cycles of major products, as well as the impact of future acquisitions and dispositions, may also materially impact the Company’s business, financial condition, or consolidated results of operations. Therefore, the results of operations for the three and nine months ended October 31, 2015 and 2014 are not necessarily indicative of the results that can be expected for the entire fiscal year ended January 31, 2016.
Operating Expenses Restatement and Remediation Related [Policy Text Block]	Restatement and remediation related expenses primarily include legal, accounting and third party consulting fees associated with (i) the restatement of certain of the Company's consolidated financial statements and other financial information from fiscal 2009 to fiscal 2013, (ii) the Audit Committee investigation to review the Company's accounting practices, (iii) incremental external audit and supplemental procedures by the Company in connection with the preparation of its financial statements, and (iv) other incremental legal, accounting and consulting fees incurred as a result of the Company's restatement related investigation, regulatory requests for information or in conjunction with the Company's remediation of material weaknesses and other control deficiencies identified during the restatement. Restatement and remediation related expenses incurred by the Company were insignificant and $2.1 million, respectively, during the three months ended October 31, 2015 and 2014 and $0.8 million and $19.7 million, respectively, during the nine months ended October 31, 2015 and 2014, which are recorded in “restatement and remediation related expenses” in the Consolidated Statement of Income.
Gain (Loss) Related to Litigation Settlement [Policy Text Block]	The Company has been a claimant in proceedings seeking damages from certain manufacturers of LCD flat panel and cathode ray tube displays. The Company reached settlement agreements with certain manufacturers in the amount of $3.0 million and $5.1 million, respectively, during the three months ended October 31, 2015 and 2014, and $63.1 million and $5.1 million, respectively, during the nine months ended October 31, 2015 and 2014, net of estimated attorney fees and expenses.
Accounts Receivable Purchase Facility Program, Policy [Policy Text Block]	The Company has uncommitted accounts receivable purchase agreements under which certain accounts receivable may be sold, without recourse, to third-party financial institutions. Under these programs, the Company may sell certain accounts receivable in exchange for cash less a discount, as defined in the agreements. Available capacity under these programs, which the Company uses as a source of working capital funding, is dependent on the level of accounts receivable eligible to be sold into these programs and the financial institutions' willingness to purchase such receivables. In addition, certain of these agreements also require that the Company continue to service, administer and collect the sold accounts receivable. At October 31, 2015 and January 31, 2015, the Company had a total of $391.1 million and $310.9 million, respectively, of accounts receivable sold to and held by financial institutions under these agreements. During the three months ended October 31, 2015 and 2014, discount fees recorded under these facilities were $0.9 million and $0.7 million, respectively, and during the nine months ended October 31, 2015 and 2014, discount fees recorded under these facilities were $2.9 million and $3.4 million, respectively. These discount fees are included as a component of "other expense (income), net" in the Consolidated Statement of Income.
Recently Adopted Accounting Standards [Policy Text Block]	In April 2015, the Financial Accounting Standards Board (“FASB”) issued an accounting standard which requires debt issuance costs to be presented in the balance sheet as a deduction from the carrying value of the associated debt liability. In August 2015, the FASB issued an accounting standard to clarify that for line-of-credit arrangements an entity can continue to defer and present debt issuance costs as an asset and subsequently amortize the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The new guidance should be applied on a retrospective basis. The Company early adopted these standards in the first and third quarter of fiscal 2016, respectively. The adoption of these standards did not have a material impact on the Company's consolidated financial position and had no impact on its consolidated income, comprehensive income or cash flows.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued Accounting Standards In April 2015, the FASB issued an accounting standard which provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the license element should be accounted for consistent with the acquisition of other software licenses. If the cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The standard will be effective for the Company beginning with the quarter ending April 30, 2016. The Company is currently in the process of assessing what impact this new standard may have on its consolidated financial position and results of operations. In May 2014, the FASB issued an accounting standard which will supersede all existing revenue recognition guidance under current GAAP. The new standard requires the recognition of revenue to depict the transfer of promised goods or services to customers while exercising extensive judgment and use of estimates. The standard will be effective for the Company beginning with the quarter ending April 30, 2018. The Company would have the option to adopt one year earlier and the standard may be adopted with either a full retrospective or a modified retrospective approach. The Company is currently in the process of assessing what impact this new standard may have on its consolidated financial position and results of operations.
