Accounting Policies [Abstract]
Accounting Policies	Accounting policies Basis of presentation The unaudited interim financial information of Kellogg Company (the Company) included in this report reflects all adjustments, all of which are of a normal and recurring nature, that management believes are necessary for a fair statement of the results of operations, comprehensive income, financial position, equity and cash flows for the periods presented. This interim information should be read in conjunction with the financial statements and accompanying footnotes within the Company’s 2018 Annual Report on Form 10-K. The condensed balance sheet information at December 29, 2018 was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States. The results of operations for the quarterly period ended September 28, 2019 are not necessarily indicative of the results to be expected for other interim periods or the full year. Accounts payable The Company has agreements with certain third parties to provide accounts payable tracking systems which facilitates participating suppliers’ ability to monitor and, if elected, sell payment obligations from the Company to designated third-party financial institutions. Participating suppliers may, at their sole discretion, make offers to sell one or more payment obligations of the Company prior to their scheduled due dates at a discounted price to participating financial institutions. The Company’s goal in entering into these agreements is to capture overall supplier savings, in the form of payment terms or vendor funding, created by facilitating suppliers’ ability to sell payment obligations, while providing them with greater working capital flexibility. We have no economic interest in the sale of these suppliers’ receivables and no direct financial relationship with the financial institutions concerning these services. The Company’s obligations to its suppliers, including amounts due and scheduled payment dates, are not impacted by suppliers’ decisions to sell amounts under these arrangements. However, the Company’s right to offset balances due from suppliers against payment obligations is restricted by this agreement for those payment obligations that have been sold by suppliers. As of September 28, 2019 , $809 million of the Company’s outstanding payment obligations had been placed in the accounts payable tracking system, and participating suppliers had sold $572 million of those payment obligations to participating financial institutions. As of December 29, 2018, $893 million of the Company’s outstanding payment obligations had been placed in the accounts payable tracking system, and participating suppliers had sold $701 million of those payment obligations to participating financial institutions. New accounting standards adopted in the period Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. In February 2018, the Financial Accounting Standards Board (FASB) issued an Accounting Standard Update (ASU) permitting a company to reclassify the disproportionate income tax effects of the Tax Cuts and Jobs Act of 2017 on items within accumulated other comprehensive income (AOCI) to retained earnings. We elected to adopt the ASU effective in the first quarter of 2019 and reclassified the disproportionate income tax effect recorded within AOCI to retained earnings. This resulted in a decrease to AOCI and an increase to retained earnings of $22 million . The adjustment primarily related to deferred taxes previously recorded for pension and other postretirement benefits, as well as hedging positions for debt and net investment hedges. Leases. In February 2016, the FASB issued an ASU requiring the recognition of lease assets and lease liabilities by lessees for all leases with terms greater than 12 months. The distinction between finance leases and operating leases remains, with similar classification criteria as current GAAP to distinguish between capital and operating leases. The principal difference from prior guidance is that the lease assets and lease liabilities arising from operating leases will be recognized on the Consolidated Balance Sheet. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. The Company adopted the ASU in the first quarter of 2019, using the optional transition method that allows for a cumulative-effect adjustment in the period of adoption with no restatement of prior periods. The Company elected the package of practical expedients permitted under the transition guidance that allows for the carry forward of historical lease classifications and consistent treatment of initial direct costs for existing leases. The Company also elected to apply the practical expedient that allows the continued historical treatment of land easements. The Company did not elect the practical expedient for the use of hindsight in evaluating the expected lease term of existing leases. The adoption of the ASU resulted in the recording of operating lease assets and operating lease liabilities of approximately $453 million and $461 million , respectively, as of December 30, 2018. The difference between the additional lease assets and lease liabilities, represents existing deferred rent and prepaid lease balances that were reclassified on the balance sheet. The adoption of the ASU did not have a material impact to the Company’s Consolidated Statements of Income or Cash Flows.

Sale of Accounts Receivable

Transfers and Servicing of Financial Assets [Abstract]
Transfers and Servicing of Financial Assets [Text Block]	Sale of accounts receivable The Company has a program in which a discrete group of customers are allowed to extend their payment terms in exchange for the elimination of early payment discounts (Extended Terms Program). The Company has two Receivable Sales Agreements (Monetization Programs) described below, which are intended to directly offset the impact the Extended Terms Program would have on the days-sales-outstanding (DSO) metric that is critical to the effective management of the Company's accounts receivable balance and overall working capital. The Monetization Programs are designed to effectively offset the impact on working capital of the Extended Terms Program. The Monetization Programs sell, on a revolving basis, certain trade accounts receivable invoices to third party financial institutions. Transfers under these agreements are accounted for as sales of receivables resulting in the receivables being de-recognized from the Consolidated Balance Sheet. The Monetization Programs provide for the continuing sale of certain receivables on a revolving basis until terminated by either party; however the maximum receivables that may be sold at any time is $1,033 million . The Company has no retained interest in the receivables sold, however the Company does have collection and administrative responsibilities for the sold receivables. The Company has not recorded any servicing assets or liabilities as of September 28, 2019 and December 29, 2018 for these agreements as the fair value of these servicing arrangements as well as the fees earned were not material to the financial statements. Accounts receivable sold of $918 million and $900 million remained outstanding under these arrangements as of September 28, 2019 and December 29, 2018 , respectively. The proceeds from these sales of receivables are included in cash from operating activities in the Consolidated Statement of Cash Flows in the period of sale. The recorded net loss on sale of receivables was $6 million and $21 million for the quarter and year-to-date periods ended September 28, 2019 , respectively and was $7 million and $20 million for the quarter and year-to-date periods ended September 29, 2018 , respectively. The recorded loss is included in Other income and expense. Other programs Additionally, from time to time certain of the Company's foreign subsidiaries will transfer, without recourse, accounts receivable invoices of certain customers to financial institutions. These transactions are accounted for as sales of the receivables resulting in the receivables being de-recognized from the Consolidated Balance Sheet. Accounts receivable sold of $23 million and $93 million remained outstanding under these programs as of September 28, 2019 and December 29, 2018

Disposal Groups, Including Discontinued Operations, Disclosure [Text Block]	Divestiture On July 28, 2019, the Company completed its sale of selected cookies, fruit and fruit-flavored snacks, pie crusts, and ice cream cones businesses to Ferrero International S.A. (“Ferrero”) for approximately $1.3 billion in cash, subject to a working capital adjustment mechanism. Both the total assets and net assets of the businesses were approximately $1.3 billion , resulting in a net pre-tax gain of $38 million during the quarter ended September 28, 2019, recorded in Other income and (expense), after including related costs to sell of $14 million . Additionally, the Company recognized curtailment gains related to the divestiture totaling $17 million in our U.S. pension and nonpension postretirement plans. The operating results for these businesses were primarily included in the North America reporting segment prior to the sale. Proceeds from the divestiture were used primarily to redeem $1.0 billion of debt during the third quarter. The Company expects to pay approximately $260 million of cash taxes on the divestiture in the fourth quarter of 2019. In connection with the sale, the Company entered into a transition services agreement (TSA) with Ferrero, under which the Company will provide certain services to Ferrero to help facilitate an orderly transition of the businesses following the sale. In return for these services, Ferrero is required to pay certain agreed upon fees that are designed to reimburse the Company for certain costs incurred by the Company in providing such services, plus specified nominal margins which are immaterial. The TSA provides for a term of services starting at the sale completion date and continuing for a period of up to 18 months.

Acquisitions, West Africa Investments, Goodwill and Other Intangible Assets [Abstract]
Acquisitions, West Africa Investments, Goodwill and Other Intangible Assets	Acquisitions, West Africa investments, goodwill and other intangible assets Multipro acquisition On May 2, 2018, the Company (i) acquired an incremental 1% ownership interest in Multipro, a leading distributor of a variety of food products in Nigeria and Ghana, and (ii) exercised its call option (Purchase Option) to acquire a 50% interest in Tolaram Africa Foods, PTE LTD (TAF), a holding company with a 49% equity interest in an affiliated food manufacturer, resulting in the Company having a 24.5% interest in the affiliated food manufacturer. The aggregate cash consideration paid was approximately $419 million and was funded through cash on hand and short-term borrowings, which was refinanced with long-term borrowings in May 2018. As part of the consideration for the acquisition, an escrow established in connection with the original Multipro investment in 2015, which represented a significant portion of the amount paid for the Company’s initial investment, was released by the Company. As a result of the Company’s incremental ownership interest in Multipro and concurrent changes to the shareholders' agreement, the Company has a 51% controlling interest in and is consolidating Multipro. The acquisition was accounted for as a business combination and the assets and liabilities of Multipro were included in the September 28, 2019 and December 29, 2018 Consolidated Balance Sheet and the results of its operations have been included in the Consolidated Statement of Income subsequent to the acquisition date within the AMEA reporting segment. The Multipro investment was previously accounted for under the equity method of accounting and the Company recorded our share of equity income or loss from Multipro within Earnings (loss) from unconsolidated entities. In connection with the business combination, the Company recognized a one-time, non-cash gain in the second quarter of 2018 on the disposition of our previously held equity interest in Multipro of $245 million , which is included within Earnings (loss) from unconsolidated entities. The Company's September 29, 2018 quarter and year-to-date consolidated unaudited pro forma historical net sales and net income, as if Multipro had been acquired at the beginning of 2018, exclusive of the non-cash $245 million gain on the disposition of the equity interest recognized in the second quarter of 2018, are estimated as follows: Quarter ended Year-to-date period ended (millions) September 29, 2018 September 29, 2018 Net sales $ 3,469 $ 10,512 Net Income attributable to Kellogg Company $ 380 $ 1,420 Investment in TAF The investment in TAF, our interest in an affiliated food manufacturer, is accounted for under the equity method of accounting with the Company’s share of equity income or loss being recognized within Earnings (loss) from unconsolidated entities. The $458 million aggregate of the consideration paid upon exercise and the historical cost value of the Purchase Option was compared to the estimated fair value of the Company’s ownership percentage of TAF and the Company recognized a one-time, non-cash loss in the second quarter of 2018 of $45 million within Earnings (loss) from unconsolidated entities, which represents an other than temporary excess of cost over fair value of the investment. The difference between the carrying amount of TAF and the underlying equity in net assets is primarily attributable to brand and customer list intangible assets, a portion of which is being amortized over future periods, and goodwill. Goodwill and Intangible Assets Changes in the carrying amount of goodwill, intangible assets subject to amortization, consisting primarily of customer relationships, distribution agreements, and indefinite-lived intangible assets, consisting of brands, are presented in the following tables: Carrying amount of goodwill (millions) North America Europe Latin America AMEA Consoli- dated December 29, 2018 $ 4,611 $ 346 $ 218 $ 875 $ 6,050 Divestiture (191 ) — — — (191 ) Currency translation adjustment — (10 ) (10 ) 3 (17 ) September 28, 2019 $ 4,420 $ 336 $ 208 $ 878 $ 5,842 Intangible assets subject to amortization Gross carrying amount (millions) North America Europe Latin America AMEA Consoli- dated December 29, 2018 $ 74 $ 39 $ 63 $ 432 $ 608 Additions 2 — — — 2 Divestiture (12 ) — — — (12 ) Currency translation adjustment — (3 ) (4 ) 1 (6 ) September 28, 2019 $ 64 $ 36 $ 59 $ 433 $ 592 Accumulated Amortization December 29, 2018 $ 39 $ 18 $ 12 $ 18 $ 87 Amortization 2 2 3 13 20 Divestiture (12 ) — — — (12 ) Currency translation adjustment — (1 ) (1 ) (1 ) (3 ) September 28, 2019 $ 29 $ 19 $ 14 $ 30 $ 92 Intangible assets subject to amortization, net December 29, 2018 $ 35 $ 21 $ 51 $ 414 $ 521 Amortization (2 ) (2 ) (3 ) (13 ) (20 ) Currency translation adjustment — (2 ) (3 ) 2 (3 ) September 28, 2019 $ 33 $ 17 $ 45 $ 403 $ 498 For intangible assets in the preceding table, amortization was $20 million and $16 million for the year-to-date periods ended September 28, 2019 and September 29, 2018 , respectively. The currently estimated aggregate annual amortization expense for full-year 2019 is approximately $27 million . Intangible assets not subject to amortization (millions) North America Europe Latin America AMEA Consoli- dated December 29, 2018 $ 1,985 $ 401 $ 73 $ 381 $ 2,840 Additions 18 — — — 18 Divestiture (765 ) — — — (765 ) Currency translation adjustment — (16 ) (5 ) 2 (19 ) September 28, 2019 $ 1,238 $ 385 $ 68 $ 383 $ 2,074 Impairment Testing Goodwill is tested for impairment at least annually or whenever events or changes in circumstances indicate the carrying value of the asset may be impaired, including a change in reporting units or composition of reporting units as a result of a re-organization in internal reporting structures. For the goodwill impairment test, the fair value of the reporting units are estimated based on market multiples. This approach employs market multiples based on either sales or earnings before interest, taxes, depreciation and amortization for companies that are comparable to the Company’s reporting units. In the event the fair value determined using the market multiple approach is close to carrying value, the Company may supplement the fair value determination using discounted cash flows. The assumptions used for the impairment test are consistent with those utilized by a market participant performing similar valuations for the Company’s reporting units. These estimates are made using various inputs including historical data, current and anticipated market conditions, management plans, and market comparables. On December 30, 2018 the Company reorganized our North American business. The reorganization eliminated the legacy business unit structure and internal reporting. In addition, the Company changed the internal reporting provided to the chief operating decision maker (CODM) and segment manager. As a result, the Company reevaluated its operating segments and reporting units. In addition, we transferred the management of our Middle East, North Africa, and Turkey businesses from Kellogg Europe to Kellogg AMEA, effective December 30, 2018. Refer to Note 13, Reportable Segments for further details on these changes. As a result of these changes in operating segments and related reporting units, the Company re-allocated goodwill between reporting units where necessary and compared the carrying value to the fair value of each impacted reporting unit on a before and after basis. This evaluation was only required to be performed on reporting units impacted by the changes noted above. Effective December 30, 2018 in North America, the previous U.S. Snacks, U.S. Morning Foods, U.S. Specialty Channels, U.S. Frozen Foods, Kashi, Canada and RX operating segments are now a single operating segment (Kellogg North America). At the beginning of 2019, the Company evaluated the related impacted reporting units for impairment on a before and after basis and concluded that the fair values of each reporting unit exceeded their carrying values. On a before basis, the previous Kashi reporting unit's percentage of excess of fair value over carrying value was approximately 18% using the same methodology as the 2018 annual impairment analysis, which was performed as of the beginning of the fourth quarter of 2018. The fair value of the previous Kashi reporting unit was estimated primarily based on a multiple of net sales and discounted cash flows. Approximately $46 million of goodwill was re-allocated between the impacted reporting units within Kellogg Europe and Kellogg AMEA related to the transfer of businesses between these operating segments. The Company performed a goodwill evaluation of the impacted reporting units on a before and after basis and concluded that the fair value of the impacted reporting units exceeded their carrying values. Additionally, during the first quarter of 2019, the Company determined that it was more likely than not that the Company would be selling selected cookies, fruit and fruit-flavored snacks, pie crusts, and ice cream cones businesses within the North America reporting unit. As a result, the Company performed a goodwill impairment evaluation on the North America reporting unit in the first quarter of 2019 and concluded that the fair value exceeded the carrying value of the reporting unit. During the second quarter of 2019, the Company entered into a definitive agreement to sell the businesses to Ferrero. The sale was completed during the third quarter of 2019 and resulted in the divestiture of the net assets and liabilities of these businesses, included in the North America reporting unit, including $191 million of Goodwill and $765 million of Net Intangibles. In addition to the cash consideration received, the Company entered into a perpetual royalty-free licensing agreement with Ferrero, allowing Kellogg the use of certain brand names for cracker products. The license agreement was fair valued at $18 million

Restructuring and Related Activities [Abstract]
Restructuring and Cost Reduction Activities	Restructuring Programs The Company views its restructuring programs as part of its operating principles to provide greater visibility in achieving its long-term profit growth targets. Initiatives undertaken are currently expected to recover cash implementation costs within a 3 to 5 -year period of completion. Upon completion (or as each major stage is completed in the case of multi-year programs), the project begins to deliver cash savings and/or reduced depreciation. Project K Since inception, Project K has reduced the Company’s cost structure, and is expected to provide enduring benefits, including an optimized supply chain infrastructure, an efficient global business services model, a global focus on categories, increased agility from a more efficient organization design, and improved effectiveness in go-to-market models. These benefits are intended to strengthen existing businesses in core markets, increase growth in developing and emerging markets, and drive an increased level of value-added innovation. The Company approved all remaining Project K initiatives as of the end of 2018 and implementation of these remaining initiatives will be completed in 2019. Project charges, after-tax costs and annual savings remain in line with previous estimates. The Company currently anticipates that the program will result in total pre-tax charges, once all phases are implemented, of $1.6 billion , with after-tax cash costs, including incremental capital investments, estimated to be approximately $1.2 billion . Based on current estimates and actual charges to date, the Company expects the total project charges will consist of asset-related costs of approximately $500 million which will consist primarily of asset impairments, accelerated depreciation and other exit-related costs; employee-related costs of approximately $400 million which includes severance, pension and other termination benefits; and other costs of approximately $700 million which consists primarily of charges related to the design and implementation of global business capabilities and a more efficient go-to-market model. The Company currently expects that total pre-tax charges related to Project K will impact reportable segments as follows: North America (approximately 65% ), Europe (approximately 22% ), Latin America (approximately 3% ), AMEA (approximately 6% ), and Corporate (approximately 4% ). During the quarter and year-to-date period ended September 28, 2019 , the Company recorded total net charges of $15 million and $38 million , respectively related to Project K. During the quarter and year-to-date period ended September 29, 2018 , the Company recorded total net charges of $34 million and $59 million , respectively related to Project K.

Other Programs During the second quarter of 2019, the Company announced a reorganization plan for the European reportable segment designed to simplify the organization, increase organizational efficiency, and enhance key processes. The overall project is expected to be substantially completed by December 31, 2020. The project is expected to result in cumulative pretax net charges of approximately $40 million , including certain non-cash credits. Cash costs are expected to be approximately $50 million . The total expected charges will include severance and other termination benefits and charges related to relocation, third party legal and consulting fees, and contract termination costs. During the year-to-date periods ended September 28, 2019 , the Company recorded total charges of $32 million related to this initiative. These charges were recorded in SG&A expense. Additionally during the second quarter of 2019, the Company announced a reorganization plan which primarily impacts the North America reportable segment. The reorganization plan is designed to simplify the organization that supports the remaining North America reportable segment after the divestiture and related transition. The overall project is expected to be substantially completed by December 31, 2020. The overall project is expected to result in cumulative pretax charges of approximately $30 million . Cash costs are expected to approximate the pretax charges. Total expected charges will include severance and other termination benefits and charges related to third party consulting fees. During the quarter and year-to-date periods ended September 28, 2019 , the Company recorded total charges of $3 million and $21 million , respectively, related to this initiative.

Equity [Abstract]
Equity	Equity Earnings per share Basic earnings per share is determined by dividing net income by the weighted average number of common shares outstanding during the period. Diluted earnings per share is similarly determined, except that the denominator is increased to include the number of additional common shares that would have been outstanding if all dilutive potential common shares had been issued. Dilutive potential common shares consist principally of employee stock options issued by the Company, restricted stock units, and to a lesser extent, certain contingently issuable performance shares. There were 10 million and 14 million anti-dilutive potential common shares excluded from the reconciliation for the quarter and year-to-date periods ended September 28, 2019 . There were 7 million and 6 million anti-dilutive potential common shares excluded from the reconciliation for the quarter and year-to-date periods ended September 29, 2018 . Please refer to the Consolidated Statement of Income for basic and diluted earnings per share for the quarters ended September 28, 2019 and September 29, 2018 . Share repurchases In December 2017, the board of directors approved a new authorization to repurchase up to $1.5 billion of our common stock beginning in January 2018 through December 2019. As of September 28, 2019 , $960 million remains available under the authorization. During the year-to-date period ended September 28, 2019 , the Company repurchased approximately 4 million shares of common stock for a total of $220 million . During the year-to-date period ended September 29, 2018 , the Company repurchased approximately 2 million shares of common stock for a total of $120 million . Comprehensive income Comprehensive income includes net income and all other changes in equity during a period except those resulting from investments by or distributions to shareholders. Other comprehensive income consists of foreign currency translation adjustments, fair value adjustments associated with cash flow hedges and adjustments for net experience losses and prior service cost related to employee benefit plans, net of related tax effects.

Leases [Abstract]
Leases	Leases The Company leases certain warehouses, equipment, vehicles, and office space primarily through operating lease agreements. Finance lease obligations and activity are not material to the Consolidated Financial Statements. Lease obligations are primarily for real estate assets, with the remainder related to manufacturing and distribution related equipment, vehicles, information technology equipment, and rail cars. Leases with an initial term of 12 months or less are not recorded on the balance sheet. A portion of the Company's real estate leases include future variable rental payments that include inflationary adjustment factors. The future variability of these adjustments is unknown and therefore not included in the minimum lease payments. The Company's lease agreements do not contain any material residual value guarantees or material restrictive covenants. The leases have remaining terms which range from less than 1 year to 10 years and the majority of leases provide the Company with the option to exercise one or more renewal terms. The length of the lease term used in recording lease assets and lease liabilities is based on the contractually required lease term adjusted for any options to renew or early terminate the lease that are reasonably certain of being executed. The Company combines lease and non-lease components together in determining the minimum lease payments for the majority of leases. The Company has elected to not combine lease and non-lease components for certain asset types in service-related agreements that include significant production related costs. The Company has closely analyzed these agreements to ensure any embedded costs related to the securing of the leased asset is properly segregated and accounted for in measuring the lease assets and liabilities. The majority of the leases do not include a stated interest rate, and therefore the Company's periodic incremental borrowing rate is used to determine the present value of lease payments. This rate is calculated based on a collateralized rate for the specific currencies used in leasing activities and the borrowing ability of the applicable Company legal entity. For the initial implementation of the lease standard, the incremental borrowing rate at December 29, 2018 was used to present value operating lease assets and liabilities. The Company recorded operating lease costs of $36 million and $100 million for the quarter and year-to-date periods ended September 28, 2019. Lease related costs associated with variable rent, short-term leases, and sale-leaseback arrangements, as well as sublease income, are each immaterial. (millions) Quarter ended September 28, 2019 Year-to-date period ended September 28, 2019 Other information Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 39 $ 102 Right-of-use assets obtained in exchange for new operating lease liabilities $ 67 $ 87 Weighted-average remaining lease term - operating leases 7 years Weighted-average discount rate - operating leases 3.0% At September 28, 2019, future maturities of operating leases were as follows: (millions) Operating leases 2019 (three months remaining) 36 2020 111 2021 86 2022 69 2023 57 2024 and beyond 166 Total minimum payments $ 525 Less interest $ (54 ) Present value of lease liabilities $ 471 Operating lease payments presented in the table above exclude $82 million of minimum lease payments for real-estate leases signed but not yet commenced. The leases are expected to commence in 2019 and 2020. As previously disclosed in our 2018 Annual Report on Form 10-K and under previous lease standard (Topic 840), at December 29, 2018, future minimum annual lease commitments under non-cancelable operating leases were as follows: (millions) Operating leases 2019 121 2020 97 2021 73 2022 57 2023 48 2024 and beyond 129 Total minimum payments $ 525 Rent expense on operating leases for the year ended December 29, 2018 was $133 million .

Stock Compensation

Share-based Payment Arrangement [Abstract]
Stock Compensation	Stock compensation The Company uses various equity-based compensation programs to provide long-term performance incentives for its global workforce. Currently, these incentives consist principally of stock options, restricted stock units, and to a lesser extent, executive performance shares and restricted stock grants. The Company also sponsors a discounted stock purchase plan in the United States and matching-grant programs in several international locations. Additionally, the Company awards restricted stock to its outside directors. The interim information below should be read in conjunction with the disclosures included within the stock compensation footnote of the Company’s 2018 Annual Report on Form 10-K. The Company classifies pre-tax stock compensation expense in COGS and SG&A expense principally within its Corporate segment. For the periods presented, compensation expense for all types of equity-based programs and the related income tax benefit recognized was as follows: Quarter ended Year-to-date period ended (millions) September 28, 2019 September 29, 2018 September 28, 2019 September 29, 2018 Pre-tax compensation expense $ 14 $ 13 $ 46 $ 46 Related income tax benefit $ 4 $ 3 $ 12 $ 11 During the year-to-date period ended September 28, 2019 , the Company granted approximately 0.9 million restricted stock units at a weighted average cost of $56 per share and 2.8 million non-qualified stock options at a weighted average cost of $7 per share. Terms of these grants and the Company’s methods for determining grant-date fair value of the awards were consistent with that described within the stock compensation footnote in the Company’s 2018 Annual Report on Form 10-K. Performance shares In the first quarter of 2019, the Company granted performance shares to a limited number of senior executive-level employees, which entitle these employees to receive a specified number of shares of the Company’s common stock upon vesting. The number of shares earned could range between 0% and 200% of the target amount depending upon performance achieved over the three year vesting period. The performance conditions of the award include organic net sales growth and total shareholder return (TSR) of the Company’s common stock relative to a select group of peer companies. A Monte Carlo valuation model was used to determine the fair value of the awards. The TSR performance metric is a market condition. Therefore, compensation cost of the TSR condition is fixed at the measurement date and is not revised based on actual performance. The TSR metric was valued as a multiplier of possible levels of organic net sales growth achievement. Compensation cost related to organic net sales growth performance is revised for changes in the expected outcome. The 2019 target grant currently corresponds to approximately 236,000 shares, with a grant-date fair value of $59 per share. The 2016 performance share award, payable in stock, was settled at 85% of target in February 2019 for a total dollar equivalent of $6 million .

Additionally, the Company was required to remeasure those plans. The Company recorded a mark-to-market loss of $8 million in our U.S. pension plan due to a lower discount rate and a reduction of the expected return on assets from 7.5% to 7.0% based on an updated target portfolio mix. These decreases were partially offset by better than expected asset returns. We recorded a mark-to-market gain of $55 million related to the remeasurement of a U.S. nonpension postretirement plan as a result of better than expected asset returns, partially offset by a lower discount rate and a reduction of the expected return on assets from 7.5% to 7.0% based on an updated target portfolio mix. For the quarter and year-to-date periods ended September 28, 2019 , the Company recognized a loss of $15 million and $26 million , respectively, related to the remeasurement of a U.S. pension plan as current year distributions are expected to exceed service and interest costs resulting in settlement accounting for that particular plan. The amount of the remeasurement loss recognized was due primarily to a lower discount rate relative to the previous measurement. During the third quarter of 2018, the Company recognized a curtailment gain of $30 million as certain European pension plans were frozen as of December 31, 2018 in conjunction with Project K restructuring activity. The Company remeasured the benefit obligation for the impacted pension plan resulting in a mark-to-market gain of $33 million . The gain was due primarily to plan asset returns in excess of the expected rate of return and a favorable change in the discount rate relative to prior year end. For the quarter and year-to-date periods ended September 29, 2018, the Company recognized mark-to-market gains of $3 million and $14 million , respectively, related to the remeasurement of a U.S. pension plan as current year distributions are expected to exceed service and interest costs resulting in settlement accounting for that particular plan. The amount of the remeasurement gain recognized was due primarily to a favorable change in the discount rate relative to the previous measurement. Company contributions to employee benefit plans are summarized as follows: (millions) Pension Nonpension postretirement Total Quarter ended: September 28, 2019 $ 2 $ 5 $ 7 September 29, 2018 $ — $ 5 $ 5 Year-to-date period ended: September 28, 2019 $ 6 $ 13 $ 19 September 29, 2018 $ 266 $ 13 $ 279 Full year: Fiscal year 2019 (projected) $ 7 $ 18 $ 25 Fiscal year 2018 (actual) $ 270 $ 17 $ 287 Prior year contributions included $250 million of pre-tax discretionary contributions to U.S. plans in the second quarter of 2018 designated for the 2017 tax year. Plan funding strategies may be modified in response to management's evaluation of tax deductibility, market conditions, and competing investment alternatives. Multi-employer pension plan exit liability During the third quarter of 2019, the Company incurred a pre-tax charge of $132 million due to withdrawing from two multi-employer pension plans. While this is our best estimate of the ultimate cost of withdrawing from the plans at this time, the actual cost could differ based on final funding assessments. Any changes to the estimate will be recorded in the period identified. The cash obligation is approximately $8 million annually for 20 years

Income Tax Disclosure [Abstract]
Income Taxes	Income taxes The consolidated effective tax rate for the quarter ended September 28, 2019 was 27% as compared to 15% in the same quarter of the prior year. The effective tax rate for the third quarter of 2019 was unfavorably impacted by a permanent basis difference in the assets sold to Ferrero partially offset by the resolution of an uncertain tax position. The effective tax rate for the third quarter of 2018 benefited from a $16 million reduction of income tax expense related to the updated estimate of the Company's U.S. Tax Reform transition tax liability. The consolidated effective tax rate for the year-to-date periods ended September 28, 2019 and September 29, 2018 was 22% and 14% , respectively. The effective tax rate for the year-to-date period ended September 28, 2019 was unfavorably impacted by a permanent basis difference in the assets sold to Ferrero. The effective tax rate for the year-to-date period ended September 29, 2018 benefited from a reduction of income tax expense related to the updated estimate of the Company's transition tax liability, a discretionary pension contribution, and a $44 million discrete tax benefit as a result of the remeasurement of deferred taxes following a legal entity restructuring. As a result of the divestiture of selected cookies, fruit and fruit-flavored snacks, pie crusts, and ice cream cones businesses during the third quarter of 2019, the Company reclassified approximately $200 million of deferred tax liabilities to current tax liability and recognized approximately $60 million of current tax liability related to permanent basis differences on the assets sold to Ferrero. The Company expects to pay cash taxes of approximately $260 million in the fourth quarter of 2019 related to the divestiture. As of September 28, 2019 , the Company classified $19 million of unrecognized tax benefits as a net current liability. Management’s estimate of reasonably possible changes in unrecognized tax benefits during the next twelve months consists of the current liability balance expected to be settled within one year, offset by approximately $2 million of projected additions related primarily to ongoing intercompany transfer pricing activity. Management is currently unaware of any issues under review that could result in significant additional payments, accruals or other material deviation in this estimate. The Company’s total gross unrecognized tax benefits as of September 28, 2019 was $86 million . Of this balance, $78 million represents the amount that, if recognized, would affect the Company’s effective income tax rate in future periods. December 29, 2018 $ 97 Tax positions related to current year: Additions 2 Reductions — Tax positions related to prior years: Additions — Reductions (12 ) Settlements — Lapse in statute of limitations (1 ) September 28, 2019 $ 86 The accrual balance for tax-related interest was approximately $11 million at September 28, 2019 . During the third quarter of 2019, the Company settled a tax matter resulting in an $11 million reduction of the accrual.

Derivative Instruments and Fair Value Measurements [Abstract]
Derivative Instruments and Fair Value Measurements	Derivative instruments and fair value measurements The Company is exposed to certain market risks such as changes in interest rates, foreign currency exchange rates, and commodity prices, which exist as a part of its ongoing business operations. Management uses derivative and nonderivative financial instruments and commodity instruments, including futures, options, and swaps, where appropriate, to manage these risks. Instruments used as hedges must be effective at reducing the risk associated with the exposure being hedged. The Company designates derivatives and nonderivative hedging instruments as cash flow hedges, fair value hedges, net investment hedges, and uses other contracts to reduce volatility in interest rates, foreign currency and commodities. As a matter of policy, the Company does not engage in trading or speculative hedging transactions. Total notional amounts of the Company’s derivative instruments as of September 28, 2019 and December 29, 2018 were as follows: (millions) September 28, December 29, Foreign currency exchange contracts $ 2,250 $ 1,863 Cross-currency contracts 1,480 1,197 Interest rate contracts 1,856 1,608 Commodity contracts 319 417 Total $ 5,905 $ 5,085 Following is a description of each category in the fair value hierarchy and the financial assets and liabilities of the Company that were included in each category at September 28, 2019 and December 29, 2018 , measured on a recurring basis. Level 1 – Financial assets and liabilities whose values are based on unadjusted quoted prices for identical assets or liabilities in an active market. For the Company, level 1 financial assets and liabilities consist primarily of commodity derivative contracts. Level 2 – Financial assets and liabilities whose values are based on quoted prices in markets that are not active or model inputs that are observable either directly or indirectly for substantially the full term of the asset or liability. For the Company, level 2 financial assets and liabilities consist of interest rate swaps, cross-currency swaps and over-the-counter commodity and currency contracts. The Company’s calculation of the fair value of interest rate swaps is derived from a discounted cash flow analysis based on the terms of the contract and the interest rate curve. Over-the-counter commodity derivatives are valued using an income approach based on the commodity index prices less the contract rate multiplied by the notional amount. Foreign currency contracts are valued using an income approach based on forward rates less the contract rate multiplied by the notional amount. Cross-currency contracts are valued based on changes in the spot rate at the time of valuation compared to the spot rate at the time of execution, as well as the change in the interest differential between the two currencies. The Company’s calculation of the fair value of level 2 financial assets and liabilities takes into consideration the risk of nonperformance, including counterparty credit risk. Level 3 – Financial assets and liabilities whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement. These inputs reflect management’s own assumptions about the assumptions a market participant would use in pricing the asset or liability. The Company did not have any level 3 financial assets or liabilities as of September 28, 2019 or December 29, 2018 . The following table presents assets and liabilities that were measured at fair value in the Consolidated Balance Sheet on a recurring basis as of September 28, 2019 and December 29, 2018 : Derivatives designated as hedging instruments September 28, 2019 December 29, 2018 (millions) Level 1 Level 2 Total Level 1 Level 2 Total Assets: Cross-currency contracts: Other assets $ — $ 143 $ 143 $ — $ 79 $ 79 Interest rate contracts: Other assets (a) — 11 11 — 17 17 Total assets $ — $ 154 $ 154 $ — $ 96 $ 96 Liabilities: Interest rate contracts: Other liabilities (a) — (13 ) (13 ) — (22 ) (22 ) Total liabilities $ — $ (13 ) $ (13 ) $ — $ (22 ) $ (22 ) (a) The fair value of the related hedged portion of the Company's long-term debt, a level 2 liability, was $0.7 billion and $1.6 billion as of September 28, 2019 and December 29, 2018 , respectively.

The carrying value of this debt was approximately $2.5 billion and $2.6 billion as of September 28, 2019 and December 29, 2018 , respectively. The following amounts were recorded on the Consolidated Balance Sheet related to cumulative basis adjustments for existing fair value hedges as of September 28, 2019 and December 29, 2018 . (millions) Line Item in the Consolidated Balance Sheet in which the hedged item is included Carrying amount of the hedged liabilities Cumulative amount of fair value hedging adjustment included in the carrying amount of the hedged liabilities (a) September 28, December 29, September 28, December 29, Interest rate contracts Current maturities of long-term debt $ — $ 503 $ — $ 3 Interest rate contracts Long-term debt $ 3,114 $ 3,354 $ 27 $ (18 ) (a) The current maturities of hedged long-term debt includes $3 million of hedging adjustment on discontinued hedging relationships as of December 29, 2018 . The hedged long-term debt includes $16 million and $(12) million of hedging adjustment on discontinued hedging relationships as of September 28, 2019 and December 29, 2018 , respectively. The Company has elected to not offset the fair values of derivative assets and liabilities executed with the same counterparty that are generally subject to enforceable netting agreements. However, if the Company were to offset and record the asset and liability balances of derivatives on a net basis, the amounts presented in the Consolidated Balance Sheet as of September 28, 2019 and December 29, 2018 would be adjusted as detailed in the following table: As of September 28, 2019: Gross Amounts Not Offset in the Consolidated Balance Sheet Amounts Presented in the Consolidated Balance Sheet Financial Instruments Cash Collateral Received/ Posted Net Amount Total asset derivatives $ 181 $ (38 ) $ (9 ) $ 134 Total liability derivatives $ (42 ) $ 38 $ — $ (4 ) As of December 29, 2018: Gross Amounts Not Offset in the Consolidated Balance Sheet Amounts Presented in the Consolidated Balance Sheet Financial Instruments Cash Collateral Received/ Posted Net Amount Total asset derivatives $ 102 $ (27 ) $ (2 ) $ 73 Total liability derivatives $ (35 ) $ 27 $ — $ (8 ) The effect of derivative instruments on the Consolidated Statements of Income and Comprehensive Income for the quarters ended September 28, 2019 and September 29, 2018 was as follows: Derivatives and non-derivatives in net investment hedging relationships (millions) Gain (loss) recognized in AOCI Gain (loss) excluded from assessment of hedge effectiveness Location of gain (loss) in income of excluded component September 28, September 29, September 28, September 29, Foreign currency denominated long-term debt $ 99 $ 16 $ — $ — Cross-currency contracts 49 9 9 4 Interest expense Total $ 148 $ 25 $ 9 $ 4 Derivatives not designated as hedging instruments (millions) Location of gain (loss) recognized in income Gain (loss) recognized in income September 28, September 29, Foreign currency exchange contracts COGS $ 7 $ 1 Foreign currency exchange contracts Other income (expense), net — 2 Commodity contracts COGS (21 ) (2 ) Total $ (14 ) $ 1 The effect of derivative instruments on the Consolidated Statements of Income and Comprehensive Income for the year-to-date periods ended September 28, 2019 and September 29, 2018 was as follows: Derivatives and non-derivatives in net investment hedging relationships (millions) Gain (loss) recognized in AOCI Gain (loss) excluded from assessment of hedge effectiveness Location of gain (loss) in income of excluded component September 28, September 29, September 28, September 29, Foreign currency denominated long-term debt $ 115 $ 89 $ — $ — Cross-currency contracts 64 36 25 10 Interest expense Total $ 179 $ 125 $ 25 $ 10 Derivatives not designated as hedging instruments (millions) Location of gain (loss) recognized in income Gain (loss) recognized in income September 28, September 29, Foreign currency exchange contracts COGS $ (3 ) $ 8 Foreign currency exchange contracts Other income (expense), net (1 ) (2 ) Foreign currency exchange contracts SGA — 1 Commodity contracts COGS (13 ) (5 ) Total $ (17 ) $ 2 The effect of fair value and cash flow hedge accounting on the Consolidated Income Statement for the quarters ended September 28, 2019 and September 29, 2018 : September 28, 2019 September 29, 2018 (millions) Interest Expense Interest Expense Total amounts of income and expense line items presented in the Consolidated Income Statement in which the effects of fair value or cash flow hedges are recorded $ 72 $ 72 Gain (loss) on fair value hedging relationships: Interest contracts: Hedged items (5 ) 9 Derivatives designated as hedging instruments 7 (9 ) Gain (loss) on cash flow hedging relationships: Interest contracts: Amount of gain (loss) reclassified from AOCI into income 1 (2 ) The effect of fair value and cash flow hedge accounting on the Consolidated Income Statement for the year-to-date periods ended September 28, 2019 and September 29, 2018 : September 28, 2019 September 29, 2018 (millions) Interest Expense Interest Expense Total amounts of income and expense line items presented in the Consolidated Income Statement in which the effects of fair value or cash flow hedges are recorded $ 221 $ 213 Gain (loss) on fair value hedging relationships: Interest contracts: Hedged items (42 ) 34 Derivatives designated as hedging instruments 44 (30 ) Gain (loss) on cash flow hedging relationships: Interest contracts: Amount of gain (loss) reclassified from AOCI into income (2 ) (6 ) During the next 12 months, the Company expects $9 million of net deferred losses reported in AOCI at September 28, 2019 to be reclassified to income, assuming market rates remain constant through contract maturities. Certain of the Company’s derivative instruments contain provisions requiring the Company to post collateral on those derivative instruments that are in a liability position if the Company’s credit rating is at or below BB+ (S&P), or Baa1 (Moody’s). The fair value of all derivative instruments with credit-risk-related contingent features in a liability position on September 28, 2019 was not material. In addition, certain derivative instruments contain provisions that would be triggered in the event the Company defaults on its debt agreements. There were no collateral posting as of September 28, 2019 triggered by credit-risk-related contingent features. Other fair value measurements The following is a summary of the carrying and market values of the Company's available for sale securities: September 28, 2019 December 29, 2018 Unrealized Unrealized (millions) Cost Gain (Loss) Market Value Cost Gain (Loss) Market Value Corporate bonds $ — $ — $ — $ 59 $ — $ 59 During the third quarter of 2019, the Company's investments in level 2 corporate bonds were sold for $63 million resulting in a gain of $4 million , recorded in Other income and (expense). The market values of the Company's investments in level 2 corporate bonds were based on matrices or models from pricing vendors. Unrealized gains and losses were included in the Consolidated Statement of Comprehensive Income. Additionally, these investments were recorded within Other current assets and Other assets on the Consolidated Balance Sheet, based on the maturity of the individual security. Financial instruments The carrying values of the Company’s short-term items, including cash, cash equivalents, accounts receivable, accounts payable, notes payable and current maturities of long-term debt approximate fair value. The fair value of the Company’s long-term debt, which are level 2 liabilities, is calculated based on broker quotes. The fair value and carrying value of the Company's long-term debt was $8.3 billion and $7.7 billion , respectively, as of September 28, 2019 . The fair value and carrying value of the Company's long-term debt were both $8.2 billion as of December 29, 2018. Counterparty credit risk concentration and collateral requirements The Company is exposed to credit loss in the event of nonperformance by counterparties on derivative financial and commodity contracts. Management believes a concentration of credit risk with respect to derivative counterparties is limited due to the credit ratings and use of master netting and reciprocal collateralization agreements with the counterparties and the use of exchange-traded commodity contracts. Master netting agreements apply in situations where the Company executes multiple contracts with the same counterparty. Certain counterparties represent a concentration of credit risk to the Company. If those counterparties fail to perform according to the terms of derivative contracts, this would result in a loss to the Company of approximately $112 million , net of collateral already received from those counterparties, as of September 28, 2019 . For certain derivative contracts, reciprocal collateralization agreements with counterparties call for the posting of collateral in the form of cash, treasury securities or letters of credit if a fair value loss position to the Company or its counterparties exceeds a certain amount. In addition, the Company is required to maintain cash margin accounts in connection with its open positions for exchange-traded commodity derivative instruments executed with the counterparty that are subject to enforceable netting agreements. As of September 28, 2019 , the Company had no collateral posting requirements related to reciprocal collateralization agreements and collected approximately $19 million of collateral related to reciprocal collaterization agreements which is reflected as an increase in other liabilities. As of September 28, 2019 the Company posted $10 million in margin deposits for exchange-traded commodity derivative instruments, which was reflected as an increase in accounts receivable, net on the Consolidated Balance Sheet. Management believes concentrations of credit risk with respect to accounts receivable is limited due to the generally high credit quality of the Company’s major customers, as well as the large number and geographic dispersion of smaller customers. However, the Company conducts a disproportionate amount of business with a small number of large multinational grocery retailers, with the five largest accounts encompassing approximately 19% of consolidated trade receivables at September 28, 2019 .

Segment Reporting [Abstract]
Reportable Segments	Reportable segments Kellogg Company is the world’s leading producer of cereal, second largest producer of crackers, and a leading producer of savory snacks and frozen foods. Additional product offerings include toaster pastries, cereal bars, veggie foods and noodles. Kellogg products are manufactured and marketed globally. Principal markets for these products include the United States, United Kingdom, and Nigeria. On December 30, 2018 the Company reorganized its North American business. The reorganization eliminated the legacy business unit structure and internal reporting. In addition, the Company changed the internal reporting provided to the chief operating decision maker (CODM) and segment manager. As a result, the Company reevaluated its operating segments. In conjunction with the reorganization, certain global research and development resources and related activities were transferred from the North America business to Corporate. Prior period segment results were not restated for the transfer as the impacts were not considered material. In addition, the Company transferred its Middle East, North Africa, and Turkey businesses from Kellogg Europe to Kellogg AMEA, effective December 30, 2018. This consolidated the Company's Africa business under a single regional management team. All comparable prior periods have been restated to reflect the change. For the quarter and year-to-date periods ended September 29, 2018 , the change resulted in $65 million and $194 million , respectively, of reported net sales and $11 million and $35 million , respectively, of reported operating profit transferring from Kellogg Europe to Kellogg AMEA. The Company manages its operations through four operating segments that are based on geographic location – North America which includes U.S. businesses and Canada; Europe which consists principally of European countries; Latin America which consists of Central and South America and includes Mexico; and AMEA (Asia Middle East Africa) which consists of Africa, Middle East, Australia and other Asian and Pacific markets. These operating segments also represent our reportable segments. On July 28, 2019, the Company completed its sale of selected cookies, fruit and fruit-flavored snacks, pie crusts, and ice cream cones businesses to Ferrero for approximately $1.3 billion in cash. Both the total assets and net assets, consisting primarily of goodwill and intangibles, property, plant and equipment, and inventory, of the businesses were approximately $1.3 billion . The operating results for these businesses were primarily included in the North America reporting segment prior to the sale. The measurement of reportable segment results is based on segment operating profit which is generally consistent with the presentation of operating profit in the Consolidated Statement of Income. Reportable segment results were as follows: Quarter ended Year-to-date period ended (millions) September 28, September 29, September 28, September 29, Net sales North America $ 2,059 $ 2,188 $ 6,496 $ 6,645 Europe 527 531 1,566 1,610 Latin America 244 239 707 710 AMEA 542 511 1,586 1,265 Consolidated $ 3,372 $ 3,469 $ 10,355 $ 10,230 Operating profit North America (a)(b) $ 208 $ 330 $ 910 $ 1,114 Europe 68 63 164 210 Latin America 23 28 61 70 AMEA (c) 53 46 145 125 Total Reportable Segments 352 467 1,280 1,519 Corporate (b) (89 ) (71 ) (239 ) (139 ) Consolidated $ 263 $ 396 $ 1,041 $ 1,380 (a) During the third quarter of 2019, North America operating profit includes the recognition of multi-employer pension plan exit liabilities totaling $132 million .

Loss Contingency [Abstract]
Contingencies	Contingencies In 2016, a class action complaint was filed against Kellogg in the Northern District of California relating to statements made on packaging for certain products. In August 2019, the Court ruled in favor of the plaintiff regarding certain statements made on the Company’s products and ordered the parties to conduct settlement discussions related to all matters in dispute. As of September 28, 2019, the Company concluded that the contingency related to the unfavorable ruling was probable and estimable, resulting in a liability being recorded. On October 21, 2019, the parties filed a motion to the Court to approve a settlement. This litigation, including any potential settlement, is not expected to have a material impact on the Company’s consolidated financial statements. The Company will continue to evaluate the likelihood of potential outcomes as the litigation continues.

In February 2018, the Financial Accounting Standards Board (FASB) issued an Accounting Standard Update (ASU) permitting a company to reclassify the disproportionate income tax effects of the Tax Cuts and Jobs Act of 2017 on items within accumulated other comprehensive income (AOCI) to retained earnings. We elected to adopt the ASU effective in the first quarter of 2019 and reclassified the disproportionate income tax effect recorded within AOCI to retained earnings. This resulted in a decrease to AOCI and an increase to retained earnings of $22 million . The adjustment primarily related to deferred taxes previously recorded for pension and other postretirement benefits, as well as hedging positions for debt and net investment hedges. Leases. In February 2016, the FASB issued an ASU requiring the recognition of lease assets and lease liabilities by lessees for all leases with terms greater than 12 months. The distinction between finance leases and operating leases remains, with similar classification criteria as current GAAP to distinguish between capital and operating leases. The principal difference from prior guidance is that the lease assets and lease liabilities arising from operating leases will be recognized on the Consolidated Balance Sheet. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. The Company adopted the ASU in the first quarter of 2019, using the optional transition method that allows for a cumulative-effect adjustment in the period of adoption with no restatement of prior periods. The Company elected the package of practical expedients permitted under the transition guidance that allows for the carry forward of historical lease classifications and consistent treatment of initial direct costs for existing leases. The Company also elected to apply the practical expedient that allows the continued historical treatment of land easements. The Company did not elect the practical expedient for the use of hindsight in evaluating the expected lease term of existing leases. The adoption of the ASU resulted in the recording of operating lease assets and operating lease liabilities of approximately $453 million and $461 million , respectively, as of December 30, 2018. The difference between the additional lease assets and lease liabilities, represents existing deferred rent and prepaid lease balances that were reclassified on the balance sheet. The adoption of the ASU did not have a material impact to the Company’s Consolidated Statements of Income or Cash Flows.
