Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	Summary of Significant Accounting Policies Financial Statement Preparation The unaudited consolidated financial statements as of March 29, 2020, and for the quarter and two quarters ended March 29, 2020 and March 31, 2019, have been prepared by Starbucks Corporation under the rules and regulations of the Securities and Exchange Commission (“SEC”). In the opinion of management, the financial information for the quarter and two quarters ended March 29, 2020 and March 31, 2019 reflects all adjustments and accruals, which are of a normal recurring nature, necessary for a fair presentation of the financial position, results of operations and cash flows for the interim periods. In this Quarterly Report on Form 10-Q (“10-Q”), Starbucks Corporation is referred to as “Starbucks,” the “Company,” “we,” “us” or “our.” In the fourth quarter of fiscal 2019, we changed the classification of certain costs on our consolidated statements of earnings and revised prior period information to be consistent with the current period presentation. The most significant impact for the quarter and two quarters ended March 31, 2019, was the reclassification of our company-operated store occupancy costs from costs of sales to store operating expenses of approximately $591.8 million and $1.2 billion, respectively. We also made certain other immaterial changes. There was no impact to consolidated revenues, consolidated operating income, or net earnings per share as a result of these changes. Additionally, certain prior period information on the consolidated statements of cash flows was reclassified to conform to the current year presentation. The financial information as of September 29, 2019 is derived from our audited consolidated financial statements and notes for the fiscal year ended September 29, 2019 (“fiscal 2019”) included in Item 8 in the Fiscal 2019 Annual Report on Form 10-K (“10-K”). The information included in this 10-Q should be read in conjunction with the footnotes and management’s discussion and analysis of the consolidated financial statements in the 10-K. The results of operations for the quarter and two quarters ended March 29, 2020 are not necessarily indicative of the results of operations that may be achieved for the entire fiscal year ending September 27, 2020 (“fiscal 2020”). COVID-19 In December 2019, a novel strain of coronavirus (“COVID-19“) was first identified, and in March 2020, the World Health Organization categorized COVID-19 as a pandemic. To help control the spread of the virus and protect the health and safety of our partners (employees) and customers, we began temporarily closing or modifying operating models and hours of our retail stores in many markets both in response to governmental requirements and voluntarily, beyond the requirements of local authorities, during the second quarter of fiscal 2020. Changes made in our operations, combined with reduced customer traffic, resulted in material reductions in revenues and operating income during the second quarter of fiscal 2020, which prompted us to update our impairment analyses of our company-operated retail store portfolios and related lease right-of-use assets. For certain lower-performing stores, we compared the carrying value of store assets to undiscounted cash flows with updated assumptions on near-term profitability. As a result, we recorded an immaterial asset impairment charge within store operating expenses on our consolidated statement of earnings during the quarter ended March 29, 2020. We also evaluated our goodwill and indefinite-lived intangible assets at the end of the fiscal second quarter. Our most recently completed goodwill impairment analyses indicated significant excess fair values over carrying values across the different reporting units. Since we expect the negative financial impacts from the outbreak to be temporary, they do not significantly affect the assumptions underpinning our long-term revenue and cash flow growth rates, operating models and business strategies. Therefore, we do not consider the outbreak to be a triggering event to accelerate our annual goodwill impairment analysis. As a result, no impairment charges for goodwill and indefinite-lived intangible assets were recorded during the quarter. We evaluated our remaining assets, particularly accounts receivable and inventory. Our accounts receivable are mainly comprised of net unpaid invoices for product sales to and royalties from our licensees. Our allowance for doubtful accounts is calculated based on historical experience, licensee credit risk and application of the specific identification method. We also assessed incremental risks due to COVID-19 on our licensees' financial viability. To assist our international licensed partners during the outbreak, we provided a short-term payment extension for their outstanding receivables as of the end of the fiscal second quarter. We do not believe the form and length of the extension changed our revenue recognition policy or had a significant impact to future collectability. Based on these actions during the quarter ended March 29, 2020, we did not observe a significant deterioration of our receivable portfolio to warrant a significant increase in bad debt expense. We will continue to monitor our accounts receivable as we also committed to providing other forms of relief to certain licensees during the third quarter of fiscal 2020, which may reduce our revenues. Our inventories are stated at the lower of cost (primarily moving average cost) or net realizable value. We record reserves for obsolete and slow-moving inventory and for estimated shrinkage between physical inventory counts. During the fiscal quarter ended March 29, 2020, we recorded significant inventory write-offs due to expired or the expected expiration of perishable ingredients and products as a result of excess inventory due to the temporary closure of our retail stores. See Note 5 , Inventories, for additional details. Depending on the pace of reopening of company-operated stores as well as future customer behaviors, among other factors, we may incur additional inventory write-offs during the third quarter of fiscal 2020. During the second quarter of fiscal 2020, we received an immaterial amount of COVID-19-related rent concessions for certain stores in China, generally correlating with the limited time period our stores were closed during stay-at-home mandates. Consistent with updated guidance from the Financial Accounting Standards Board (“FASB”) in April 2020, we have elected to treat COVID-19-related rent concessions as variable rent. While we are having ongoing conversations with landlords in various markets in seeking commercially reasonable lease concessions given the current environment, we have not yet confirmed significant concessions for the remainder of the year. On March 27, 2020, the U.S. government enacted the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), which among other things, provides employer payroll tax credits for wages paid to employees who are unable to work during the COVID-19 outbreak and options to defer payroll tax payments. Based on our preliminary evaluation of the CARES Act, we qualify for certain employer payroll tax credits as well as the deferral of payroll and other tax payments in the future, which will be treated as government subsidies to offset relating operating expenses. During the quarter ended March 29, 2020, the qualified payroll tax credits reduced our store operating expenses by approximately $35 million on our consolidated statement of earnings. We expect to record additional payroll tax credits from the U.S. and other governments primarily in our fiscal third quarter to offset qualified wages paid to our partners. We intend to defer qualified payroll and other tax payments as permitted by the CARES Act. We recorded our income tax expense, deferred tax assets and related liabilities based on management’s best estimates. Additionally, we assessed the likelihood of realizing the benefits of our deferred tax assets. As of the end of the fiscal quarter, we did not record significant valuation allowance adjustments based on available evidence. However, we will continue to monitor the realizability of our deferred tax assets, particularly in certain foreign jurisdictions where the outbreak has started to create significant net operating losses. Our ability to recover these deferred tax assets depends on several factors, including our results of operations and our ability to project future taxable income in those jurisdictions. If we determine that some portion of the tax benefit will not be realized, we would record a valuation allowance, which would increase our income tax expense. Total deferred tax assets as of the end of the fiscal second quarter were approximately $1.7 billion, of which approximately $100 million related to foreign jurisdictions where we expect to incur significant net operating losses in the near term, although the risks of failing to realize these benefits vary across the jurisdictions. The COVID-19 pandemic remains a rapidly evolving situation. The continuation of the outbreak may cause prolonged periods of store closures and modified operating schedules and may result in changes in customer behaviors, including a potential reduction in consumer discretionary spending in our company-operated and licensed stores. These may lead to increased asset recovery and valuation risks, such as impairment of our company-operated store and other assets and an inability to realize deferred tax assets due to sustaining losses in certain jurisdictions. The uncertainties in the global economy will likely impact the financial viability of our suppliers, licensees and other business partners, which may interrupt our supply chain, limit our ability to collect receivables and require other changes to our operations. These and other factors will adversely impact our net revenues, operating income and earnings per share financial measures. Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In the second quarter of fiscal 2020, we adopted the new guidance from the FASB on simplifying the accounting for income taxes by removing certain exceptions to the general principles. The guidance was adopted on a prospective basis and had no material impact on the consolidated financial statements. On September 30, 2019, we adopted the new guidance from the FASB on the recognition and measurement of leases utilizing the modified retrospective approach. As a result, the prior period information reported under the previous lease guidance has not been restated. As permitted under the new FASB lease guidance, we elected the package of practical expedients, which allowed us to retain our prior conclusions regarding lease identification, classification and initial direct costs. For our lease agreements with lease and non-lease components, we elected the practical expedient to account for these as a single lease component for all underlying classes of assets. For our adoption, we did not elect to use hindsight for our existing leases. Additionally, for short-term leases with an initial lease term of 12 months or less and with purchase options we are reasonably certain will not be exercised, we elected to not record right-of-use assets or corresponding lease obligations on our consolidated balance sheet. We will continue to record rent expense for each short-term lease on a straight-line basis over the lease term. The new FASB lease guidance had a material impact on our consolidated balance sheet; however, it did not have a material impact on our consolidated statement of earnings. The most material impact was the recognition of right-of-use assets of $8.4 billion upon adoption, with corresponding lease liabilities of $9.0 billion relating to our operating leases. Existing deferred rent and tenant improvement allowances of approximately $568.0 million, previously recorded within other long-term liabilities, were recorded as an offset to our gross operating lease right-of-use assets. Additionally, pursuant to the transition guidance, we derecognized build-to-suit lease assets, previously recorded in property, plant and equipment, net, along with the corresponding liabilities on the consolidated balance sheet as of September 30, 2019. Accordingly, these leases have been recorded as operating leases as of the adoption date and are now included in operating lease, right-of-use assets and operating lease liabilities on the consolidated balance sheet. As of the adoption date, accumulated deficit within shareholder's equity on our consolidated balance sheet decreased by $17.3 million, primarily related to the derecognition of build-to-suit leasing arrangements. See Note 9 , Leases, for further discussion regarding the adoption of the new guidance. In the first quarter of fiscal 2020, we adopted the new guidance from the FASB on the reclassification of certain tax effects from accumulated other comprehensive income (“AOCI”) which permits entities to reclassify the stranded tax effects resulting from the Tax Cuts and Jobs Act (the “Tax Act”) from AOCI to retained earnings. The guidance was adopted prospectively with no material impact on the consolidated financial statements as of March 29, 2020. Recent Accounting Pronouncements Not Yet Adopted

Revenue from Contract with Customer	Deferred Revenue Our deferred revenue primarily consists of the up-front prepaid royalty from Nestlé, for which we have continuing performance obligations to support the Global Coffee Alliance, and our unredeemed stored value card liability and unredeemed loyalty points (“Stars”) associated with our loyalty program. At March 29, 2020, the current and long-term deferred revenue related to the Nestlé up-front payment was $176.5 million and $6.6 billion, respectively. During the quarter and two quarters ended March 29, 2020, we recognized $44.2 million and $88.4 million in current deferred revenue, respectively, related to amortization of the up-front payment. For the quarter and two quarters ended March 31, 2019, we recognized $43.7 million and $87.8 million in current deferred revenue, respectively, related to amortization of the up-front payment.

Ltd, converting this operation to a fully licensed market. This transaction resulted in a pre-tax gain of $601.9 million, which was included in net gains resulting from divestiture of certain operations on our consolidated statements of earnings.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments Interest Rates From time to time, we enter into designated cash flow hedges to manage the variability in cash flows due to changes in benchmark interest rates. We enter into interest rate swap agreements and treasury locks, which are synthetic forward sales of U.S. treasury securities settled in cash based upon the difference between an agreed-upon treasury rate and the prevailing treasury rate at settlement. These agreements are cash settled at the time of the pricing of the related debt. Each derivative agreement's gain or loss is recorded in AOCI and is subsequently reclassified to interest expense over the life of the related debt. To hedge the exposure to changes in the fair value of our fixed-rate debt, we enter into interest rate swap agreements, which are designated as fair value hedges. The changes in fair values of these derivative instruments and the offsetting changes in fair values of the underlying hedged debt due to changes in the relevant benchmark interest rates are recorded in interest expense. Refer to Note 8 , Debt, for additional information on our long-term debt. Foreign Currency To reduce cash flow volatility from foreign currency fluctuations, we enter into forward and swap contracts to hedge portions of cash flows of anticipated intercompany royalty payments, inventory purchases, and intercompany borrowing and lending activities. The resulting gains and losses from these derivatives are recorded in AOCI and subsequently reclassified to revenue, cost of sales, or interest income and other, net, respectively, when the hedged exposures affect net earnings. From time to time, we may enter into financial instruments, including, but not limited to, forward and swap contracts or foreign currency-denominated debt, to hedge the currency exposure of our net investments in certain international operations. The resulting gains and losses from these derivatives are generally recorded in AOCI and are subsequently reclassified to net earnings when the hedged net investment is either sold or substantially liquidated. Foreign currency forward and swap contracts not designated as hedging instruments are used to mitigate the foreign exchange risk of certain other balance sheet items. Gains and losses from these derivatives are largely offset by the financial impact of translating foreign currency-denominated payables and receivables; these gains and losses are recorded in interest income and other, net. Commodities Depending on market conditions, we may enter into coffee forward contracts, futures contracts, and collars to hedge anticipated cash flows under our price-to-be-fixed green coffee contracts, which are described further in Note 5, Inventories, or our longer-dated forecasted coffee demand where underlying fixed price and price-to-be-fixed contracts are not yet available. The resulting gains and losses are recorded in AOCI and are subsequently reclassified to cost of sales when the hedged exposure affects net earnings. Depending on market conditions, we may also enter into dairy forward contracts and futures contracts to hedge a portion of anticipated cash flows under our dairy purchase contracts and our forecasted dairy demand. The resulting gains or losses are recorded in AOCI and are subsequently reclassified to cost of sales when the hedged exposure affects net earnings. To mitigate the price uncertainty of a portion of our future purchases, including dairy products, diesel fuel and other commodities, we enter into swap contracts, futures and collars that are not designated as hedging instruments. The resulting gains and losses are recorded in interest income and other, net to help offset price fluctuations on our beverage, food, packaging and transportation costs, which are included in cost of sales on our consolidated statements of earnings. Cash flow hedges related to anticipated transactions are designated and documented at the inception of each hedge. Cash flows from hedging transactions are classified in the same categories as the cash flows from the respective hedged items. For de-designated cash flow hedges in which the underlying transactions are no longer likely to occur, the related accumulated derivative gains or losses are recognized in interest income and other, net on our consolidated statements of earnings. During the quarter ended March 29, 2020, we de-designated certain cash flow hedges due to the global COVID-19 impacts, resulting in the release of an insignificant net gain from AOCI to our consolidated statement of earnings. We continue to believe transactions relating to our other designated cash flow hedges are probable to occur as of the end of the fiscal quarter.

Inventory levels vary due to seasonality, commodity market supply and price fluctuations. As of March 29, 2020, we had committed to purchasing green coffee totaling $861 million under fixed-price contracts and an estimated $463 million under price-to-be-fixed contracts. We expect to take physical delivery for these contracts. A portion of our price-to-be-fixed contracts are effectively fixed through the use of futures. See Note 3 , Derivative Financial Instruments, for further discussion. Price-to-be-fixed contracts are purchase commitments whereby the quality, quantity, delivery period and other negotiated terms are agreed upon, but the date, and therefore the price, at which the base “C” coffee commodity price component will be fixed has not yet been established. For most contracts, either Starbucks or the seller has the option to “fix” the base “C” coffee commodity price prior to the delivery date. For other contracts, Starbucks and the seller may agree upon pricing parameters determined by the base “C” coffee commodity price. Until prices are fixed, we estimate the total cost of these purchase commitments. We believe, based on relationships established with our suppliers in the past and continuous monitoring, the risk of non-delivery on these purchase commitments is remote.

Leases [Abstract]
Leases	Leases The following significant lease accounting policies from our most recent Annual Report on Form 10-K have been updated to reflect the adoption of FASB's new guidance on the recognition and measurement of leases. The majority of our leases are operating leases for our company-operated retail store locations. We also lease, among other things, roasting, distribution and warehouse facilities and office space for corporate administrative purposes. We do not enter into lease transactions with related parties. We categorize leases as either operating or finance leases at the commencement date of the lease. Operating lease agreements may contain tenant improvement allowances, rent holidays, rent escalation clauses and/or contingent rent provisions. We have lease agreements with lease and non-lease components, which are accounted for together as a single lease component for all underlying classes of assets. We recognize a right-of-use (“ROU”) asset and lease liability for each operating and finance lease with a contractual term greater than 12 months at the time of lease inception. We do not record leases with an initial term of 12 months or less on our consolidated balance sheet but continue to record rent expense on a straight-line basis over the lease term. Our leases often include options to extend or terminate at our sole discretion, which are included in the determination of lease term when they are reasonably certain to be exercised. Our lease liability represents the present value of future lease payments over the lease term. Given our policy election to combine lease and non-lease components, we also consider fixed common area maintenance (“CAM”) part of our fixed future lease payments; therefore, fixed CAM is also included in our lease liability. We cannot determine the interest rate implicit in each of our leases. Therefore, we use market and term-specific incremental borrowing rates. Our incremental borrowing rate for a lease is the rate of interest we expect to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms. Because we do not borrow on a collateralized basis, we consider a combination of factors, including our credit-adjusted risk-free interest rate, the risk profile and funding cost of the specific geographic market of the lease, the lease term and the effect of adjusting the rate to reflect consideration of collateral. Our credit-adjusted risk-free rate takes into consideration interest rates we pay on our unsecured long-term bonds as well as quoted interest rates obtained from financial institutions. Total lease costs recorded as rent and other occupancy costs include fixed operating lease costs, variable lease costs and short-term lease costs. Most of our real estate leases require we pay certain expenses, such as CAM costs, real estate taxes and other executory costs, of which the fixed portion is included in operating lease costs. We recognize operating lease costs on a straight-line basis over the lease term. In addition to the above costs, variable lease costs also include amounts based on a percentage of gross sales in excess of specified levels and are recognized when probable and are not included in determining the present value of our lease liability. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. A significant majority of our leases are related to our company-operated stores, and their related costs are recorded within store operating expenses. The ROU asset is measured at the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, initial direct costs, and any tenant improvement allowances received. For operating leases, ROU assets are reduced over the lease term by the recognized straight-line lease expense less the amount of accretion of the lease liability determined using the effective interest method. For finance leases, ROU assets are amortized on a straight-line basis over the shorter of the useful life of the leased asset or the lease term. Interest expense on each finance lease liability is recognized utilizing the effective interest method. ROU assets are tested for impairment in the same manner as long-lived assets. Additionally, we monitor for events or changes in circumstances that may require a reassessment of one of our leases and determine if a remeasurement is required. During the second quarter of fiscal 2020, we received immaterial rent concessions related to COVID-19 company-operated store closures. The components of lease costs (in millions) : Quarter Ended Two Quarters Ended Mar 29, 2020 Mar 29, 2020 Operating lease costs (1) $ 377.4 $ 750.5 Variable lease costs 197.2 426.0 Short-term lease costs 8.3 16.6 Total lease costs $ 582.9 $ 1,193.1 (1) Operating lease costs includes an immaterial amount of sublease income.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies Disclosure [Text Block]	Commitments and Contingencies Legal Proceedings On April 13, 2010, an organization named Council for Education and Research on Toxics (“Plaintiff”) filed a lawsuit in the Superior Court of the State of California, County of Los Angeles, against the Company and certain other defendants who manufacture, package, distribute or sell brewed coffee. The lawsuit is Council for Education and Research on Toxics v. Starbucks Corporation, et al . On May 9, 2011, the Plaintiff filed an additional lawsuit in the Superior Court of the State of California, County of Los Angeles, against the Company and additional defendants who manufacture, package, distribute or sell packaged coffee. The lawsuit is Council for Education and Research on Toxics v. Brad Barry LLC, et al .. Both cases have since been consolidated and now include nearly eighty defendants, which constitute the great majority of the coffee industry in California. Plaintiff alleges that the Company and the other defendants failed to provide warnings for their coffee products of exposure to the chemical acrylamide as required under California Health and Safety Code section 25249.5, the California Safe Drinking Water and Toxic Enforcement Act of 1986, better known as Proposition 65. Plaintiff seeks equitable relief, including providing warnings to consumers of coffee products, as well as civil penalties in the amount of the statutory maximum of two thousand five hundred dollars per day per violation of Proposition 65. The Plaintiff asserts that every consumed cup of coffee, absent a compliant warning, is equivalent to a violation under Proposition 65. The Company, as part of a joint defense group organized to defend against the lawsuit, disputes the claims of the Plaintiff. Acrylamide is not added to coffee but is present in all coffee in small amounts (parts per billion) as a byproduct of the coffee bean roasting process. The Company has asserted multiple affirmative defenses. Trial of the first phase of the case commenced on September 8, 2014, and was limited to three affirmative defenses shared by all defendants. On September 1, 2015, the trial court issued a final ruling adverse to defendants on all Phase 1 defenses. Trial of the second phase of the case commenced in the fall of 2017. On May 7, 2018, the trial court issued a ruling adverse to defendants on the Phase 2 defense, the Company's last remaining defense to liability. On June 22, 2018, the California Office of Environmental Health Hazard Assessment (OEHHA) proposed a new regulation clarifying that cancer warnings are not required for coffee under Proposition 65. The case was set to proceed to a third phase trial on damages, remedies and attorneys' fees on October 15, 2018. However, on October 12, 2018, the California Court of Appeal granted the defendants request for a stay of the Phase 3 trial. On June 3, 2019, the Office of Administrative Law (OAL) approved the coffee exemption regulation. The regulation became effective on October 1, 2019. On June 24, 2019, the Court of Appeal lifted the stay of the litigation. A status conference before the trial judge to discuss the motions that each party has filed is scheduled for May 11, 2020. At this stage of the proceedings, Starbucks believes that the likelihood that the Company will ultimately incur a loss in connection with this litigation is remote. Accordingly, no loss contingency was recorded for this matter. Starbucks is party to various other legal proceedings arising in the ordinary course of business, including certain employment litigation cases that have been certified as class or collective actions, but, except as noted above, is not currently a party to any legal proceeding that management believes could have a material adverse effect on our consolidated financial position, results of operations or cash flows.
