Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying consolidated financial statements of The Home Depot, Inc. and its subsidiaries (the "Company," "Home Depot," "we," "our" or "us") have been prepared in accordance with the instructions to Form 10-Q and do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Results of operations for interim periods are not necessarily indicative of results for the entire year. As a result, these financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our 2018 Form 10-K. There were no significant changes to our significant accounting policies as disclosed in the 2018 Form 10-K, except as set forth below. Leases On February 4, 2019, we adopted the new leases standard using the modified retrospective transition method, which requires that we recognize leases differently pre- and post-adoption. See "—Recently Adopted Accounting Pronouncements—ASU No. 2016-02" below for more information. We categorize leases at their inception as either operating or finance leases. Lease agreements cover certain retail locations, office space, warehouse and distribution space, equipment, and vehicles. Most of these leases are operating leases; however, certain retail locations and equipment are leased under finance leases. Operating leases are included in operating lease right-of-use assets, current operating lease liabilities, and long-term operating lease liabilities in our consolidated balance sheets. Finance leases are included in net property and equipment, current installments of long-term debt, and long-term debt in our consolidated balance sheets. Leased assets represent our right to use an underlying asset for the lease term, and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. We use a secured incremental borrowing rate as the discount rate for present value of lease payments when the rate implicit in the contract is not readily determinable. We determine a secured rate on a quarterly basis and update the weighted average discount rate accordingly. For operating leases with variable payments dependent upon an index or rate that commenced subsequent to adoption of ASU No. 2016-02, we apply the active index or rate as of the lease commencement date. Variable lease payments not based on an index or rate are not included in the operating lease liability as they cannot be reasonably estimated and are recognized in the period in which the obligation for those payments is incurred. Leases that have a term of twelve months or less upon commencement date are considered short-term in nature. Accordingly, short-term leases are not included on the consolidated balance sheets and are expensed on a straight-line basis over the lease term, which commences on the date we have the right to control the property. Recently Adopted Accounting Pronouncements ASU No. 2018-02. In February 2018, the FASB issued ASU No. 2018-02, "Income Statement—Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income," which allows for an optional reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects as a result of the Tax Act. On February 4, 2019, we adopted ASU No. 2018-02 resulting in an increase of $31 million to retained earnings and a decrease of $31 million to accumulated other comprehensive income. ASU No. 2017-12. 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. ASU No. 2017-12 eliminates the concept of recognizing periodic hedge ineffectiveness for cash flow and net investment hedges and allows an entity to apply the shortcut method to partial-term fair value hedges of interest rate risk. On February 4, 2019, we adopted ASU No. 2017-12 with no impact to our consolidated financial statements. We expect the impact of the adoption to be immaterial to our financial position, results of operations, and cash flows on an ongoing basis. ASU No. 2016-02. In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)," which establishes a right-of-use model and requires an entity that is a lessee to recognize the right-of-use assets and liabilities arising from leases on the balance sheets. ASU No. 2016-02 also requires disclosures about the amount, timing, and uncertainty of cash flows arising from leases. Leases will be classified as finance or operating, with classification affecting both the pattern and classification of expense recognition in the statements of earnings. This guidance was subsequently amended by ASU No. 2018-01, Land Easement Practical Expedient for Transition to Topic 842; ASU No. 2018-10, Codification Improvements to Topic 842; and ASU No. 2018-11, Targeted Improvements. ASU No. 2016-02 and subsequent updates require a modified retrospective transition, with the cumulative effect of transition, including initial recognition of lease assets and liabilities for existing operating leases, as of (i) the effective date or (ii) the beginning of the earliest comparative period presented. These updates also provide a number of practical expedients for implementation which we are applying, as discussed below. On February 4, 2019 (the “effective date”), we adopted ASU No. 2016-02 and subsequent updates, collectively referred to as Topic 842, using the modified retrospective transition method. In addition, we adopted the package of practical expedients in transition, which permits us to not reassess our prior conclusions pertaining to lease identification, lease classification and initial direct costs on leases that commenced prior to our adoption of the new standard. We also elected the ongoing practical expedient to not recognize operating lease right-of-use assets and operating lease liabilities related to short-term leases. We did not elect the use-of-hindsight or land easements practical expedients. For leases beginning subsequent to the effective date, we elected to not separate lease and non-lease components for certain classes of assets including real estate and certain equipment. To determine the measurement of the lease liability for operating leases with variable payments based on an index or rate that commenced prior to the adoption of Topic 842, we elected to apply the active index or rate at the effective date. As a result of adopting Topic 842, we recognized net operating lease right-of-use assets of $5.7 billion and operating lease liabilities of $6.0 billion on the effective date. Existing prepaid rent, accrued rent, and closed store reserves were recorded as an offset to our gross operating lease right-of-use assets. The cumulative effect of the adoption resulted in an immaterial adjustment to the opening balance of retained earnings as of February 4, 2019. The standard did not have a material impact on our results of operations or cash flows. Recently Issued Accounting Pronouncements Recent accounting pronouncements pending adoption not discussed above or in the 2018 Form 10-K are either not applicable or will not have or are not expected to have a material impact on us.

Leases

On February 4, 2019, we adopted the new leases standard using the modified retrospective transition method, which requires that we recognize leases differently pre- and post-adoption. See "—Recently Adopted Accounting Pronouncements—ASU No. 2016-02" below for more information.

Most of these leases are operating leases; however, certain retail locations and equipment are leased under finance leases. Operating leases are included in operating lease right-of-use assets, current operating lease liabilities, and long-term operating lease liabilities in our consolidated balance sheets. Finance leases are included in net property and equipment, current installments of long-term debt, and long-term debt in our consolidated balance sheets.
