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.Effective September 22, 2014, the Company’s Venezuela affiliate, Corporación Clorox de Venezuela S.A. (Clorox Venezuela), discontinued its operations. Consequently, the Company reclassified the financial results of Clorox Venezuela as a discontinued operation in the condensed consolidated financial statements for all periods presented herein.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, 2016, which includes a complete set of footnote disclosures including the Company’s significant accounting policies.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                              |
| Recently Issued Accounting Standards                      | Recently Issued Accounting StandardsIn March 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (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 item(s) 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. Additionally, the new guidance limits the components that are eligible for capitalization in assets to only the service cost component. The new guidance is effective for the Company beginning in the first quarter of fiscal year 2019, with the option to early adopt in the first quarter of fiscal year 2018. The Company is currently evaluating the impact that 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 March 2016, the FASB issued ASU No. 2016-09, “Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting,” which simplifies several aspects of the accounting for share-based payment transactions, including requiring excess tax benefits and tax deficiencies to be recognized as income tax benefits or expenses in the consolidated statement of earnings. Additionally, the standard requires cash flows from excess tax benefits and deficiencies, previously classified as a financing activity, to be classified as an operating activity in the consolidated statement of cash flows. The Company adopted this guidance in the first quarter of fiscal year 2017. Excess tax benefits of $11 and $17 were recognized in the consolidated statement of earnings and classified as an operating activity in the consolidated statement of cash flows during the three and nine months ended March 31, 2017, respectively. The prior period consolidated statement of cash flows has not been adjusted as permitted. The guidance allows for a policy election to account for forfeitures as they occur rather than on an estimated basis. The Company did not make this election and will continue to account for forfeitures on an estimated basis.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. 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 April 2015, the FASB issued ASU No. 2015-03, “Simplifying the Presentation of Debt Issuance Cost,” which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The Company adopted this standard in the first quarter of fiscal year 2017 and retrospectively applied the standard to the June 30, 2016 consolidated balance sheet, resulting in an $8 reduction in Other assets and Long-term debt. The adoption had no impact on the Company’s consolidated statement of earnings or consolidated statement of cash flows.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 new guidance is effective for the Company beginning in the first quarter of fiscal year 2019, with the option to early adopt in the first quarter of fiscal year 2018. The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements. |
| Fair Value Measurements                                   | Fair Value MeasurementsFinancial 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 March 31, 2017 and June 30, 2016, the Company’s financial assets and liabilities that were measured at fair value on a recurring basis during the applicable periods included derivative financial instruments, which were classified as either Level 1 or Level 2, and trust assets to fund certain of the Company’s nonqualified deferred compensation plans, which were classified as Level 1.
