Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	In the opinion of management, the accompanying unaudited interim consolidated financial statements contain all adjustments necessary to present fairly Avnet, Inc. and its consolidated subsidiaries (the “Company” or “Avnet”) financial position, results of operations, comprehensive income and cash flows. All such adjustments are of a normal recurring nature. The preparation of financial statements in accordance with generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements. Actual results may differ from these estimates. Interim results of operations are not necessarily indicative of the results to be expected for the full fiscal year. The information included in this Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 28, 2014.
Reclassifications	Certain prior-period amounts have been reclassified to conform to the current-period presentation.
New accounting pronouncements	New accounting pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), to supersede nearly all existing revenue recognition guidance under GAAP. The core principles of ASU 2014-09 are to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. Application of the requirements of ASU 2014-09 may require more judgment and estimates within the revenue recognition process compared to existing GAAP. ASU 2014-09 is effective for the Company in the first quarter of fiscal 2018 using either of two acceptable adoption methods: (i) retrospective adoption to each prior reporting period presented with the option to elect certain practical expedients as defined within ASU 2014-09; or (ii) adoption with the cumulative effect of initially applying ASU 2014-09 recognized at the date of initial application and providing certain additional disclosures as defined within ASU 2014-09. The Company is currently evaluating the potential impact of the future adoption of ASU 2014-09 on its consolidated financial statements. In June 2014, the FASB issued an update related to accounting for share-based payments for which the terms of an award provide that a performance target could be achieved after the requisite service period. The update requires a reporting entity to treat a performance target that affects vesting and that could be achieved after the requisite service period as a performance condition, and to apply existing guidance as it relates to awards with performance conditions that affect vesting to account for such awards. The Company's adoption of this pronouncement at the beginning of fiscal year 2016 is not expected to have a material impact on the Company’s consolidated financial statements. In August 2014, the FASB issued Presentation of Financial Statements - Going Concern: Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern, which will require a reporting entity to evaluate, at each annual and interim reporting period, whether there are conditions or events that raise substantial doubt about the reporting entity's ability to continue as a going concern within one year after the date the financial statements are issued and provide related disclosures. This pronouncement is effective for the Company at the beginning of fiscal year 2017. The adoption of this pronouncement is not expected to have a material impact on the Company's consolidated financial statements or disclosures.
