Derivative Financial Instrument

Derivative Financial Instruments	6 Months Ended
	Mar. 28, 2021
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 accumulated other comprehensive income (“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 7 , 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, product and distribution costs, 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 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 4, 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 product and distribution costs 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 product and distribution costs when the hedged exposure affects net 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 probable of occurring, the related accumulated derivative gains or losses are recognized in interest income and other, net on our consolidated statements of earnings. During the quarter and two quarters ended March 29, 2020, we de-designated certain cash flow hedges due to the global COVID-19 impacts, which resulted in the release of an insignificant net gain from AOCI to our consolidated statement of earnings. There were no significant cash flow hedge de-designations in fiscal 2021. To mitigate the price uncertainty of a portion of our future purchases, including diesel fuel and other commodities, we enter into swap contracts, futures and collars that are not designated as hedging instruments.

Inventory levels vary due to seasonality, commodity market supply and price fluctuations. As of March 28, 2021, we had committed to purchasing green coffee totaling $637 million under fixed-price contracts and an estimated $654 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. 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 established relationships with our suppliers and continuous monitoring, the risk of non-delivery on these purchase commitments is remote.

Income Taxes	Income Taxes The effective tax rate for the quarter ended March 28, 2021 was 25.9% compared to 16.8% for the same quarter in fiscal 2020. The increase was primarily due to higher earnings, including the foreign rate differential on our jurisdictional mix of earnings, partially offset by lapping valuation allowances recorded against deferred tax assets of certain international jurisdictions in the prior year. The effective tax rate for the first two quarters ended March 28, 2021 was 24.5% compared to 21.1% for the same period in fiscal 2020. The increase was primarily due to higher earnings, including the foreign rate differential on our jurisdictional mix of earnings, partially offset by lapping valuation allowances recorded against deferred tax assets of certain international jurisdictions in the prior year.

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. At the status conference on August 25, 2020, the trial judge granted the defendants’ motion for summary judgment, ruling that the coffee exemption regulation is a complete defense to the Plaintiff’s complaint. The Notice of Entry of Judgment from the court was served on October 6, 2020 and the Plaintiff filed a Notice of Appeal on November 20, 2020. The court issued a briefing schedule, and the parties are working through the appellate process. Starbucks believes that the likelihood that the Company will ultimately incur a material loss in connection with this litigation is less than reasonably possible. 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.

Accounting Policies [Abstract]
Recent Accounting Pronouncements (Policies)	Summary of Significant Accounting Policies Financial Statement Preparation The unaudited consolidated financial statements as of March 28, 2021, and for the quarter and two quarters ended March 28, 2021 and March 29, 2020, 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 28, 2021 and March 29, 2020 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.” Certain prior period information on the consolidated statements of cash flows has been reclassified to conform to the current year presentation. The financial information as of September 27, 2020 is derived from our audited consolidated financial statements and notes for the fiscal year ended September 27, 2020 (“fiscal 2020”) included in Item 8 in the Fiscal 2020 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 28, 2021 are not necessarily indicative of the results of operations that may be achieved for the entire fiscal year ending October 3, 2021 (“fiscal 2021”). Additionally, our 2021 fiscal year will include 53 weeks, with the 53rd week falling in the fourth fiscal quarter. The novel coronavirus, known as the global pandemic COVID-19, was first identified in December 2019 before spreading to markets where we have company-operated or licensed stores. We have since established the necessary protocols to operate safely, and our businesses continue to recover as sales in the U.S. and China, our two lead growth markets, have returned to roughly pre-pandemic levels. As of the end of the second quarter of fiscal 2021, nearly all our company-operated and licensed stores have re-opened; however, many were operating at less than full capacity. Government Subsidies 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 for a limited period. Based on our evaluation of the CARES Act, we qualify for certain employer payroll tax credits as well as the deferral of payroll tax payments in the future. Additionally, the Canadian government enacted the Canada Emergency Wage Subsidy (“CEWS”) to help employers offset a portion of their employee wages for a limited period. We elected to treat qualified government subsidies from the U.S., Canada and other governments as offsets to the related operating expenses. During the quarter and two quarters ended March 28, 2021, qualified payroll and other credits reduced our store operating expenses by $97.4 million and $117.2 million, respectively, on our consolidated statement of earnings. 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. After netting the qualified credits against our payable, a receivable of $158.6 million was included in prepaid expenses and other current assets as of March 28, 2021. During the quarter and two quarters ended March 28, 2021, we deferred $5.2 million and $81.7 million, respectively, of qualified payroll tax payments, and as of March 28, 2021, deferred payroll tax payments of $116.4 million were included in both accrued liabilities and other long-term liabilities, respectively, on our consolidated balance sheets. Restructuring In fiscal 2020, we announced a plan to optimize our North America store portfolio, primarily in dense metropolitan markets by developing new store formats to better cater to changing customer tastes and preferences. As of March 28, 2021, we expect the total number of closures to be approximately 800 stores in the U.S. and Canada and have identified 760 stores for closure under our restructuring plans. As a result we recorded approximately $23.0 million and $95.2 million to restructuring and impairments on our consolidated statement of earnings during the quarter and two quarters ended March 28, 2021, respectively. Of these totals, $8.6 million and $51.2 million related to the impairment of store assets for which either a triggering event occurred and the assets were determined not to be recoverable or the store was permanently closed, respectively. During the quarter and two quarters ended March 28, 2021, an additional $14.4 million and $44.0 million, respectively, was associated with accelerated amortization of right-of-use (“ROU”) lease assets due to planned store closures prior to the end of contractual lease terms. For impaired store asset groups, we estimated the fair values using an income approach incorporating internal projections of revenue growth and operating expenses that are considered Level 3 fair value measurements, as well as applicable discount rates and market lease rates. The application of these projections and fair value measurements did not have a significant impact on our final impairment decisions given that we plan to fully exit the majority of these identified stores over the next 9 to 12 months. We expect total future restructuring costs, which are attributable to our Americas segment, to be approximately $30 million to $40 million. These restructuring costs primarily include accelerated amortization or impairments of ROU assets due to planned store closures prior to the end of contractual lease terms. The remaining balance includes store impairment and disposal costs not previously recorded as part of our ongoing store impairment process and employee termination costs. As we have previously recorded impairment charges for stores that may be identified for closure under our plans, and because store closure decisions are still subject to change, the final costs associated with these store closures may vary from these estimates. These costs will depend on the asset carrying value and remaining lease term of the specific stores identified. Future restructuring costs are expected to be incurred primarily over the next 9 to 12 months as stores are specifically identified for closure or, in the case of lease exit costs, either when a store ceases operations or when a reduced lease term is reasonably certain due to expected, early lease termination. As of March 28, 2021, restructuring liabilities totaling $21.4 million were included in current and non-current operating lease liability for the remaining outstanding rent liabilities due to landlords. The associated expense was recognized in fiscal 2020 or during the first two quarters of fiscal 2021 for stores that were either closed or reasonably certain to close under the plan. Additionally, $10.4 million of accrued employee termination costs was included in accrued payroll and benefits. Cash payments were $23.2 million for the first two quarters of fiscal 2021. Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board ("FASB") issued guidance replacing the incurred loss impairment methodology with a new methodology that reflects current expected credit losses on financial assets, including receivables and available-for-sale securities. The new methodology requires entities to estimate and recognize expected credit losses each reporting period. The guidance was adopted during the first quarter of fiscal 2021 under the modified retrospective approach and resulted in a $2.2 million transition adjustment to opening shareholders' retained deficit on our consolidated statements of equity.
