SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Dec. 31, 2018
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The unaudited interim condensed consolidated financial statements for the three and six months ended December 31, 2018 and 2017, in the opinion of management, reflect all adjustments (consisting of normal recurring accruals) necessary for a fair presentation of the consolidated results of operations, financial position and cash flows of The Clorox Company and its subsidiaries (the Company) for the periods presented. However, the financial results for interim periods are not necessarily indicative of the results that may be expected for a full fiscal year or for any other future period. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States (U.S. GAAP) have been omitted or condensed pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (SEC). Certain prior year reclassifications were made in the condensed consolidated statements of cash flows to conform to the current year presentation. The information in this report should be read in conjunction with the Company’s Annual Report on Form 10-K filed with the SEC for the fiscal year ended June 30, 2018, which includes a complete set of footnote disclosures, including the Company’s significant accounting policies.
Revenue Recognition	Revenue Recognition Revenue is recognized when performance obligations under the terms of the contracts with customers are satisfied. The Company's performance obligation generally consists of the promise to sell finished products to wholesalers, distributors, retailers or consumers. Control of finished products are transferred upon shipment to, or receipt at, customers' locations, as determined by the specific terms of the contract. Once control is transferred to the customer, the Company has completed its performance obligation, and revenue is recognized. After completion of the performance obligation, there is an unconditional right to consideration as outlined in the contract. A right is unconditional if nothing other than the passage of time is required before payment of that consideration is due. The Company typically collects its customer receivables within two months. All performance obligations under the terms of contracts with customers have an original duration of one year or less. The Company routinely commits to one-time or ongoing trade-promotion programs with customers and consumer coupon programs that require the Company to estimate and accrue the expected costs of such programs, which include shelf price reductions, end-of-aisle or in-store displays of the Company’s products and graphics and other trade-promotion activities conducted by the customer. The costs of such activities, defined as variable consideration under Topic 606 of the Accounting Standards Codification, "Revenue from Contracts with Customers," are netted against sales and recorded when the related sale takes place. The accruals for trade promotion programs and consumer coupon liabilities are established based on the Company’s best estimate of the amounts necessary to settle future and existing obligations for products sold as of the balance sheet date. The Company uses forecasted appropriations, historical trend analysis, and customer and sales organization inputs in determining the accruals for promotional activities, and uses historical trend experience and coupon redemption estimates for the coupon accrual requirements. The Company provides an allowance for doubtful accounts based on its historical experience and ongoing assessment of its customers’ credit risk and aging. Receivables are presented net of the allowance for doubtful accounts.
Foreign Currency Transactions and Translation	Foreign Currency Transactions and Translation Effective July 1, 2018, under the requirements of U.S. GAAP, Argentina was designated as a highly inflationary economy, since it has experienced cumulative inflation of approximately 100 percent or more over a three-year period. As a result, beginning July 1, 2018, the U.S. dollar replaced the Argentine peso as the functional currency of the Company’s subsidiaries in Argentina (collectively, "Clorox Argentina"). Consequently, gains and losses from non-U.S. dollar denominated monetary assets and liabilities for Clorox Argentina are recognized in Other (income) expense, net in the condensed consolidated statement of earnings.
Recently Issued Accounting Standards	Recently Issued Accounting Standards Recently Issued Accounting Standards Not Yet Adopted In February 2018, the Financial Accounting Standards Board (FASB) issued ASU No. 2018-02, “Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income,” which amends its guidance to allow a reclassification from Accumulated Other Comprehensive Income to Retained Earnings for the stranded income tax effects resulting from The Tax Cuts and Jobs Act of 2017 (the Tax Act). The amendments are effective for the Company beginning in the first quarter of fiscal year 2020, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements. In August 2017, the FASB issued ASU No. 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities,” which amends the hedge accounting recognition and presentation requirements to better align an entity’s risk management activities with its financial reporting. This standard also simplifies the application of hedge accounting in certain situations. The new guidance is effective for the Company beginning in the first quarter of fiscal year 2020, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment,” which eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. The new guidance is effective for the Company beginning in the first quarter of fiscal year 2021, with early adoption permitted. The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842),” which requires lessees to recognize a right-of-use asset and a lease liability for all leases with terms of more than 12 months. Recognition, measurement and presentation will depend on the classification of a lease as either a finance or an operating lease. ASU 2016-02 also requires expanded disclosures about leasing arrangements. In July 2018, the FASB issued ASU No. 2018-11, "Leases (Topic 842), Targeted Improvements," which provides an optional transition method in applying the new lease standard. Topic 842 can be applied using either a modified retrospective approach at the beginning of the earliest period presented, or, as permitted by ASU 2018-11, at the beginning of the period in which it is adopted. The Company will adopt the new standard on July 1, 2019, on a modified retrospective basis using the optional transition method, and, accordingly, will not restate comparative periods. The Company has initiated its plan for the adoption and implementation of this new accounting standard, including assessing its lease arrangements and implementing software to meet the reporting and disclosure requirements of this standard. Additionally, the Company is in the process of identifying changes to its business processes and controls to support the adoption and is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements. Refer to Note 12 of the Notes to Consolidated Financial Statements in Form 10-K for the fiscal year ended June 30, 2018 for the future minimum annual lease payments required under the Company’s existing non-cancelable operating and capital lease arrangements as of June 30, 2018. Recently Adopted Accounting Standards In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers (Topic 606),” which replaces most of the existing U.S. GAAP revenue recognition guidance and is intended to improve and converge with international standards on the financial reporting requirements for revenue from contracts with customers. The core principle of ASU 2014-09 is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. ASU 2014-09 also requires additional disclosures about the nature, timing and uncertainty of revenue and cash flows arising from contracts with customers, including information about significant judgments and changes in judgments. The Company adopted the new guidance on a modified retrospective basis effective July 1, 2018, and does not expect the guidance to have a material impact on the Company's annual consolidated financial statements. However, there will be an impact on the Company’s financial results in the interim periods due to the timing of recognition for certain trade promotion spending. Due to a change in the timing of recognition for certain trade promotion spending, the Company recorded an immaterial cumulative effect of initially applying the new guidance as an adjustment to the fiscal year 2019 opening balance of Retained earnings. Results for periods beginning on or after July 1, 2018 are recognized and presented in accordance with Topic 606, while prior period amounts have not been adjusted and continue to be reported in accordance with the prior accounting guidance under Topic 605, "Revenue Recognition." The Company has made changes to its accounting policies, business processes, systems and controls to align with the new revenue recognition guidance and disclosure requirements. In March 2017, the FASB issued ASU No. 2017-07, “Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost,” which requires presenting the service cost component of net periodic benefit cost in the same income statement line items as other employee compensation costs arising from services rendered during the period. This standard also requires that other components of the net periodic benefit cost be presented separately from the line item(s) that includes service costs and outside of any subtotal of operating income, if one is presented, on a retrospective basis. The Company adopted this new guidance in the first quarter of fiscal year 2019 and the adoption did not have a material impact on the Company's consolidated financial statements. Following the adoption of this guidance, the Company records the non-service cost components of net periodic benefit cost in Other (income) expense, net. In March 2018, the FASB issued ASU No. 2018-05, “Income Taxes (Topic 740)-Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118,” which amends its guidance to address the initial accounting for the income tax effects of the Tax Act, which was enacted on December 22, 2017 (enactment date). This new guidance allows reasonable estimates of income tax effects to be reported as provisional amounts during the measurement period, which is one year from the enactment date, when the necessary information is not available, prepared, or analyzed in sufficient detail to complete the accounting. The amendments also added specific disclosure requirements. The Company adopted this new guidance and initially recorded $81 of provisional benefits in the second quarter of fiscal year 2018. Refer to Note 6 for more information.
Fair Value Measurements	Fair Value Measurements Financial assets and liabilities measured at fair value on a recurring basis in the condensed consolidated balance sheets are required to be classified and disclosed in one of the following three categories of the fair value hierarchy: Level 1: Quoted market prices in active markets for identical assets or liabilities. Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data. Level 3: Unobservable inputs reflecting the reporting entity’s own assumptions. As of December 31, 2018 and June 30, 2018, the Company’s financial assets and liabilities that were measured at fair value on a recurring basis included derivative financial instruments, which were classified as either Level 1 or Level 2, and trust assets to fund the Company’s nonqualified deferred compensation plans, which were classified as Level 1.
Segment Results	The Company operates through strategic business units (SBUs) that are aggregated into four reportable segments based on the economics and nature of the products sold: Cleaning, Household, Lifestyle and International. Certain non-allocated administrative costs, interest income, interest expense and various other non-operating income and expenses are reflected in Corporate. Corporate assets include cash and cash equivalents, prepaid expenses and other current assets, property and equipment, other investments and deferred taxes.
