SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Dec. 31, 2019
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, 2019 and 2018, 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). 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, 2019, which includes a complete set of footnote disclosures, including the Company’s significant accounting policies.
Leases	Leases Effective July 1, 2019, the Company adopted Accounting Standards Codification 842, Leases (ASC 842). Under this guidance, the Company determines whether an arrangement contains a lease at inception by determining if the contract conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration and other facts and circumstances. Right-of-use (ROU) assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets are calculated based on the lease liability adjusted for any lease payments paid to the lessor at or before the commencement date and initial direct costs incurred by the Company and excludes any lease incentives received from the lessor. Lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term. The lease term may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option as of the commencement date of the lease, and is reviewed in subsequent periods if a triggering event occurs. As the Company’s leases typically do not contain a readily determinable implicit rate, the Company determines the present value of the lease liability using its incremental borrowing rate at the lease commencement date based on the lease term and the currency of the lease on a collateralized basis. Variable lease payments are the portion of lease payments that are not fixed over the lease term. Variable lease payments are expensed as incurred, and include certain non-lease components, such as maintenance and other services provided by the lessor, and other charges included in the lease, as applicable. The Company elected to combine lease and non-lease components as a single lease component and to exclude short-term leases, defined as leases with initial terms of 12 months or less, from its condensed consolidated balance sheet.
Recently Issued Accounting Standards	Recently Issued Accounting Standards Recently Issued Accounting Standards Not Yet Adopted In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes,” which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and clarifies and amends existing guidance to improve consistent application. The standard will be effective for the Company beginning in the first quarter of fiscal year 2022, 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 intends to adopt the standard no later than July 1, 2020. The impact of the new standard will be dependent on the specific facts and circumstances of future individual impairments, if any. Recently Adopted Accounting Standards 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 Company adopted this new guidance in the first quarter of fiscal year 2020 and the adoption did not have a material impact on the Company’s consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842),” which requires lessees to recognize a ROU 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 adopted the new standard in the first quarter of fiscal year 2020, on a modified retrospective basis using the optional transition method, and, accordingly, has not restated comparative periods; fiscal year 2019 balances and related disclosures supporting those comparative period balances continue to be presented under ASC 840, “Leases.” As allowed under the new standard, the Company elected to apply the package of practical expedients to not reassess prior conclusions related to contracts containing leases, lease classification and initial direct costs. Upon adoption, the Company recorded a cumulative effect adjustment to the opening balance of Retained earnings of $22 related primarily to the remaining deferred gain from the sale-leaseback of the Company’s general office building in Oakland, California. This new standard did not have a material impact on the Company’s condensed consolidated statement of earnings or the condensed consolidated statement of cash flows. Refer to Note 3 for more information.
Fair Value Measurement	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, 2019 and June 30, 2019, 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.
