Accounting Policies [Abstract]
Basis of Presentation and Preparation	Basis of Presentation and Preparation The consolidated financial statements include the accounts of Apple Inc. and its wholly owned subsidiaries. The preparation of these consolidated financial statements and accompanying notes in conformity with GAAP requires the use of management estimates. Certain prior period amounts in the notes to consolidated financial statements have been reclassified to conform to the current period’s presentation.
Fiscal Period	The Company’s fiscal year is the 52- or 53-week period that ends on the last Saturday of September. An additional week is included in the first fiscal quarter every five or six years to realign the Company’s fiscal quarters with calendar quarters, which occurred in the first fiscal quarter of 2023. The Company’s fiscal years 2025 and 2024 spanned 52 weeks each, whereas fiscal year 2023 spanned 53 weeks. Unless otherwise stated, references to particular years, quarters, months and periods refer to the Company’s fiscal years ended in September and the associated quarters, months and periods of those fiscal years.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements Segment Reporting Beginning with the 2025 annual reporting period, the Company adopted the FASB’s ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”), which requires the Company to disclose segment expenses that are significant and regularly provided to the Company’s chief operating decision maker (“CODM”). In addition, ASU 2023-07 requires the Company to disclose the title and position of its CODM and how the CODM uses segment profit or loss information in assessing segment performance and deciding how to allocate resources. The Company adopted ASU 2023-07 using a retrospective transition method.
Revenue	Revenue The Company records revenue net of taxes collected from customers that are remitted to governmental authorities. The Company recognizes revenue at the amount to which it expects to be entitled when control of products or services is transferred to its customers. Control is generally transferred when the Company has a present right to payment and title and the significant risks and rewards of ownership of products or services are transferred to its customers. For most of the Company’s Products net sales, control transfers when products are shipped. For the Company’s Services net sales, control transfers over time as services are delivered. Payment for Products and Services net sales is collected within a short period following transfer of control or commencement of delivery of services, as applicable. The Company records reductions to Products net sales related to future product returns, price protection and other customer incentive programs based on the Company’s expectations and historical experience. For arrangements with multiple performance obligations, which represent promises within an arrangement that are distinct, the Company allocates revenue to all distinct performance obligations based on their relative stand-alone selling prices (“SSPs”). When available, the Company uses observable prices to determine SSPs. When observable prices are not available, SSPs are established that reflect the Company’s best estimates of what the selling prices of the performance obligations would be if they were sold regularly on a stand-alone basis. The Company’s process for estimating SSPs without observable prices considers multiple factors that may vary depending upon the unique facts and circumstances related to each performance obligation including, where applicable, prices charged by the Company for similar offerings, market trends in the pricing for similar offerings, product-specific business objectives and the estimated cost to provide the performance obligation. The Company has identified the performance obligations regularly included in arrangements involving the sale of iPhone, Mac and iPad. The first material performance obligation, which represents the substantial portion of the allocated sales price, is the hardware and bundled software delivered at the time of sale. The second material performance obligation is the right to receive certain product-related bundled services, which include iCloud®, Siri® and Maps. The Company allocates revenue and any related discounts to all of its performance obligations based on their relative SSPs. Because the Company lacks observable prices for product-related bundled services, the allocation of revenue is based on the Company’s estimated SSPs. Revenue allocated to the delivered hardware and bundled software is recognized when control has transferred to the customer, which generally occurs when the product is shipped. Revenue allocated to product-related bundled services is deferred and recognized on a straight-line basis over the estimated period they are expected to be provided. For certain long-term service arrangements, the Company has performance obligations for services it has not yet delivered. For these arrangements, the Company does not have a right to bill for the undelivered services. The Company has determined that any unbilled consideration relates entirely to the value of the undelivered services. Accordingly, the Company has not recognized revenue, and does not disclose amounts, related to these undelivered services. For the sale of third-party products where the Company obtains control of the product before transferring it to the customer, the Company recognizes revenue based on the gross amount billed to customers. The Company considers multiple factors when determining whether it obtains control of third-party products, including evaluating if it can establish the price of the product, retains inventory risk for tangible products or has the responsibility for ensuring acceptability of the product. For third-party applications sold through the App Store, the Company does not obtain control of the product before transferring it to the customer. Therefore, the Company accounts for all third-party application–related sales on a net basis by recognizing in Services net sales only the commission it retains.
Share-Based Compensation	Share-Based Compensation The Company recognizes share-based compensation expense on a straight-line basis for its estimate of equity awards that will ultimately vest. The Company estimates the grant-date fair value of RSUs based on the closing price of the Company’s common stock on the date of grant.
Cash Equivalents	Cash Equivalents All highly liquid investments with maturities of three months or less at the date of purchase are treated as cash equivalents.
Trade Receivables	Trade Receivables Trade receivables are stated at transaction price.
Marketable Securities	Marketable Securities The cost of securities sold is determined using the specific identification method. The Company’s investments in marketable debt securities have been classified and accounted for as available-for-sale. The Company classifies marketable debt securities as either current or non-current based on each instrument’s underlying maturity.
Inventories	Inventories Inventories are measured using the first-in, first-out method.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are stated at cost. Depreciation on property, plant and equipment is recognized on a straight-line basis.
Derivative Instruments	Derivative Instruments The Company presents derivative assets and liabilities at their gross fair values in the Consolidated Balance Sheets. All derivative instruments are recorded in the Consolidated Balance Sheets at fair value. The accounting treatment for derivative gains and losses is based on intended use and hedge designation. Gains and losses arising from amounts that are included in the assessment of cash flow hedge effectiveness are initially deferred in accumulated other comprehensive income/(loss) and subsequently reclassified into earnings when the hedged transaction affects earnings, and in the same line item in the Consolidated Statements of Operations. Gains and losses arising from amounts that are included in the assessment of fair value hedge effectiveness are recognized in the Consolidated Statements of Operations line item to which the hedge relates along with offsetting losses and gains related to the change in value of the hedged item. For derivative instruments designated as cash flow and fair value hedges, amounts excluded from the assessment of hedge effectiveness are recognized on a straight-line basis over the life of the hedge in the Consolidated Statements of Operations line item to which the hedge relates. Changes in the fair value of amounts excluded from the assessment of hedge effectiveness are recognized in other comprehensive income/(loss). Gains and losses arising from changes in the fair values of derivative instruments that are not designated as accounting hedges are recognized in the Consolidated Statements of Operations. The Company classifies cash flows related to derivative instruments in the same section of the Consolidated Statements of Cash Flows as the items being hedged, which are generally classified as operating activities.
Income Taxes	Income Taxes The Company records certain deferred tax assets and liabilities in connection with the minimum tax on certain foreign earnings created by the TCJA.
Leases	Leases The Company combines and accounts for lease and nonlease components as a single lease component for leases of corporate and retail facilities. The discount rates related to the Company’s lease liabilities are generally based on estimates of the Company’s incremental borrowing rate, as the discount rates implicit in the Company’s leases cannot be readily determined.
Fair Value Measurements	The valuation techniques used to measure the fair values of the Company’s Level 2 financial instruments, which generally have counterparties with high credit ratings, are based on quoted market prices or model-driven valuations using significant inputs derived from or corroborated by observable market data.
Segment Reporting	The Company manages its business primarily on a geographic basis. The Company’s CEO is its CODM. The Company’s reportable segments consist of the Americas, Europe, Greater China, Japan and Rest of Asia Pacific. Americas includes both North and South America. Europe includes European countries, as well as India, the Middle East and Africa. Greater China includes China mainland, Hong Kong and Taiwan. Rest of Asia Pacific includes Australia, New Zealand and those Asian countries not included in the Company’s other reportable segments. Although the reportable segments provide similar hardware and software products and similar services, each one is managed separately to better align with the location of the Company’s customers and distribution partners and the unique market dynamics of each geographic region. The CODM uses segment net sales and operating income information to make certain decisions, such as product and service pricing, and to decide how to allocate resources related to sales activities and marketing investments. Net sales for geographic segments are generally based on the location of customers and sales through the Company’s retail stores located in those geographic locations. Operating income for each segment consists of net sales to third parties, related cost of sales, and operating expenses directly attributable to the segment. The information provided to the CODM for purposes of making decisions and assessing segment performance excludes asset information.
