Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Business The Home Depot, Inc., together with its subsidiaries (the "Company," "Home Depot," "we," "our" or "us"), is a home improvement retailer that sells a wide assortment of building materials, home improvement products, lawn and garden products, and décor items and provides a number of services, in stores and online. We operate in the U.S., including the Commonwealth of Puerto Rico and the territories of the U.S. Virgin Islands and Guam, Canada, and Mexico. Consolidation and Presentation Our consolidated financial statements include our accounts and those of our wholly-owned subsidiaries. All significant intercompany transactions have been eliminated in consolidation. Certain amounts in prior fiscal years have been reclassified to conform with the presentation adopted in the current fiscal year. Our fiscal year is a 52- or 53-week period ending on the Sunday nearest to January 31. Fiscal 2017, 2016, and 2015 each included 52 weeks. Use of Estimates We have made a number of estimates and assumptions relating to the reporting of assets and liabilities, the disclosure of contingent assets and liabilities, and reported amounts of revenues and expenses in preparing these financial statements in conformity with GAAP. Actual results could differ from these estimates. Cash Equivalents We consider all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. Our cash equivalents are carried at fair market value and consist primarily of money market funds. Receivables The components of receivables, net, follow. in millions January 28, January 29, Card receivables $ 734 $ 729 Rebate receivables 609 625 Customer receivables 261 216 Other receivables 348 459 Receivables, net $ 1,952 $ 2,029 Card receivables consist of payments due from financial institutions for the settlement of credit card and debit card transactions. Rebate receivables represent amounts due from vendors for volume and co-op advertising rebates. Receivables due from customers relate to credit extended directly to customers by certain subsidiaries in the ordinary course of business. The valuation reserve related to accounts receivable was not material to our consolidated financial statements at the end of fiscal 2017 or 2016 . Merchandise Inventories The majority of our merchandise inventories are stated at the lower of cost (first-in, first-out) or market, as determined by the retail inventory method. As the inventory retail value is adjusted regularly to reflect market conditions, the inventory valued using the retail method approximates the lower of cost or market. Certain subsidiaries, including retail operations in Canada and Mexico, and distribution centers, record merchandise inventories at the lower of cost or market, as determined by a cost method. These merchandise inventories represent approximately 30% of the total merchandise inventories balance. We evaluate the inventory valued using a cost method at the end of each quarter to ensure that it is carried at the lower of cost or net realizable value. The valuation allowance for merchandise inventories valued under a cost method was not material to our consolidated financial statements at the end of fiscal 2017 or 2016 . Independent physical inventory counts or cycle counts are taken on a regular basis in each store and distribution center to ensure that amounts reflected in merchandise inventories are properly stated. Shrink (or in the case of excess inventory, "swell") is the difference between the recorded amount of inventory and the physical inventory. We calculate shrink based on actual inventory losses occurring as a result of physical inventory counts during each fiscal period and estimated inventory losses occurring between physical inventory counts. The estimate for shrink occurring in the interim period between physical inventory counts is calculated on a store-specific basis based on recent shrink results and current trends in the business. Property and Equipment, including Capitalized Lease Assets Buildings, furniture, fixtures, and equipment are recorded at cost and depreciated using the straight-line method over their estimated useful lives. Leasehold improvements are amortized using the straight-line method over the original term of the lease or the useful life of the improvement, whichever is shorter. The estimated useful lives of our property and equipment follow. Life Buildings 5 – 45 years Furniture, fixtures and equipment 2 – 20 years Leasehold improvements 5 – 45 years We capitalize certain costs related to the acquisition and development of software and amortize these costs using the straight-line method over the estimated useful life of the software, which is three to six years. Certain development costs not meeting the criteria for capitalization are expensed as incurred. We evaluate our long-lived assets each quarter for indicators of potential impairment. Indicators of impairment include current period losses combined with a history of losses, our decision to relocate or close a store or other location before the end of its previously estimated useful life, or when changes in other circumstances indicate the carrying amount of an asset may not be recoverable. The evaluation for long-lived assets is performed at the lowest level of identifiable cash flows, which is generally the individual store level. The assets of a store with indicators of impairment are evaluated for recoverability by comparing its undiscounted future cash flows with its carrying value. If the carrying value is greater than the undiscounted future cash flows, we then measure the asset’s fair value to determine whether an impairment loss should be recognized. If the resulting fair value is less than the carrying value, an impairment loss is recognized for the difference between the carrying value and the estimated fair value. Impairment losses are recorded as a component of SG&A. When a leased location closes, we also recognize, in SG&A, the net present value of future lease obligations less estimated sublease income. Impairments and lease obligation costs on closings and relocations were not material to our consolidated financial statements in fiscal 2017 , 2016 , or 2015 . Goodwill and Other Intangible Assets Goodwill represents the excess of purchase price over the fair value of net assets acquired. We do not amortize goodwill, but assess the recoverability of goodwill in the third quarter of each fiscal year, or more often if indicators warrant, by determining whether the fair value of each reporting unit supports its carrying value. Each fiscal year, we may assess qualitative factors to determine whether it is more likely than not that the fair value of each reporting unit is less than its carrying amount as a basis for determining whether it is necessary to complete quantitative impairment assessments, with a quantitative assessment completed at least once every three years. We completed our last quantitative assessment in fiscal 2016. In fiscal 2017 , we completed our annual assessment of the recoverability of goodwill for the U.S., Canada, and Mexico reporting units. We performed qualitative assessments, concluding that the fair value of the reporting units substantially exceeded the respective reporting unit's carrying value, including goodwill. As a result, there were no impairment charges related to goodwill for fiscal 2017 , 2016 , or 2015 . Changes in the carrying amount of our goodwill follow. in millions Fiscal Fiscal Fiscal 2017 2016 2015 Goodwill, balance at beginning of year $ 2,093 $ 2,102 $ 1,353 Acquisitions 164 — 788 Other (1) 18 (9 ) (39 ) Goodwill, balance at end of year $ 2,275 $ 2,093 $ 2,102 ————— (1) Primarily reflects the impact of foreign currency translation . We amortize the cost of other intangible assets over their estimated useful lives, which range up to 12 years, unless such lives are deemed indefinite. Intangible assets with indefinite lives are tested in the third quarter of each fiscal year for impairment, or more often if indicators warrant. Intangible assets are included in other assets. Debt Any premiums or discounts, as the case may be, associated with an issuance of long-term debt are recorded as a direct addition or deduction to the carrying value of the related senior notes and amortized over the term of those notes using the effective interest rate method. Debt issuance costs associated with an issuance of long-term debt are recorded as a direct deduction to the carrying value of the related senior notes and amortized over the term of those notes using the effective interest rate method. Derivatives We use derivative financial instruments in the management of our interest rate exposure on long-term debt and our exposure to foreign currency fluctuations. For derivatives that are designated as hedges, changes in their fair values that are considered effective are either accounted for in earnings or recognized in other comprehensive income (loss) until the hedged item is recognized in earnings, depending on the nature of the hedge. Any ineffective portion of a derivative’s change in fair value is immediately recognized in earnings. Financial instruments that do not qualify for hedge accounting are recorded at fair value with unrealized gains or losses reported in earnings. All qualifying derivative financial instruments are recognized at their fair values in either assets or liabilities at the balance sheet date and are reported on a gross basis. The fair values of our derivative financial instruments are discussed in Note 4 and Note 7 . Insurance We are self-insured for certain losses related to general liability (including product liability), workers’ compensation, employee group medical, and automobile claims. We recognize the expected ultimate cost for claims incurred (undiscounted) at the balance sheet date as a liability. The expected ultimate cost for claims incurred is estimated based upon analysis of historical data and actuarial estimates. We also maintain network security and privacy liability insurance coverage to limit our exposure to losses such as those that may be caused by a significant compromise or breach of our data security. Insurance related expenses are included in SG&A. Treasury Stock Treasury stock is reflected as a reduction of stockholders' equity at cost. We use the weighted-average purchase cost to determine the cost of treasury stock that is reissued. Revenues We recognize revenue, net of estimated returns and sales tax, at the time the customer takes possession of merchandise or when a service is performed. The liability for sales returns, including the impact to gross profit, is estimated based on historical return levels. Net sales include services revenue generated through a variety of installation, home maintenance, and professional service programs. In these programs, the customer selects and purchases material for a project, and we provide or arrange professional installation. These programs are offered through our stores and in-home sales programs. Under certain programs, when we provide or arrange the installation of a project and the subcontractor provides material as part of the installation, both the material and labor are included in services revenue. We recognize this revenue when the service for the customer is complete. When we receive payment from customers before the customer has taken possession of the merchandise or the service has been performed, the amount received is recorded as deferred revenue until the sale or service is complete. We also record deferred revenue for the sale of gift cards and recognize this revenue upon the redemption of gift cards in net sales. Gift card breakage income is recognized based upon historical redemption patterns and represents the balance of gift cards for which we believe the likelihood of redemption by the customer is remote. Gift card breakage income, which is recognized as a reduction to SG&A, follows. in millions Fiscal Fiscal Fiscal 2017 2016 2015 Gift card breakage income $ 39 $ 34 $ 27 Cost of Sales Cost of sales includes the actual cost of merchandise sold and services performed; the cost of transportation of merchandise from vendors to our distribution network, stores, or customers; shipping and handling costs from our stores or distribution network to customers; the operating cost and depreciation of our sourcing and distribution network and online fulfillment centers; and the cost of deferred interest programs offered through our PLCC programs. Cost of Credit We have agreements with third-party service providers who directly extend credit to customers, manage our PLCC program, and own the related receivables. We have evaluated the third-party entities holding the receivables under the program and concluded that they should not be consolidated. The agreement with the primary third-party service provider for our PLCC program expires in 2028 , with us having the option, but no obligation, to purchase the receivables at the end of the agreement. The deferred interest charges we incur for our deferred financing programs offered to our customers are included in cost of sales. The interchange fees charged to us for our customers’ use of the cards and any profit sharing with the third-party service providers are included in SG&A. The sum of these three components is referred to as the cost of credit of the PLCC program. Vendor Allowances Vendor allowances primarily consist of volume rebates that are earned as a result of attaining certain purchase levels and co-op advertising allowances for the promotion of vendors’ products that are typically based on guaranteed minimum amounts with additional amounts being earned for attaining certain purchase levels. These vendor allowances are accrued as earned, with those allowances received as a result of attaining certain purchase levels accrued over the incentive period based on estimates of purchases. Volume rebates and certain co-op advertising allowances earned are initially recorded as a reduction in merchandise inventories and a subsequent reduction in cost of sales when the related product is sold. Certain co-op advertising allowances that are reimbursements of specific, incremental, and identifiable costs incurred to promote vendors’ products are recorded as an offset against advertising expense in SG&A and were as follows: in millions Fiscal Fiscal Fiscal 2017 2016 2015 Specific, incremental, and identifiable co-op advertising allowances $ 198 $ 166 $ 129 Advertising Expense Television and radio advertising production costs, along with media placement costs, are expensed when the advertisement first appears. Gross advertising expense is included in SG&A. Certain co-op advertising allowances are recorded as an offset against advertising expense. in millions Fiscal Fiscal Fiscal 2017 2016 2015 Gross advertising expense $ 995 $ 955 $ 868 Income Taxes Income taxes are accounted for under the asset and liability method. We provide for federal, state, and foreign income taxes currently payable, as well as for those deferred due to timing differences between reporting income and expenses for financial statement purposes versus tax purposes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted income tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in income tax rates is recognized as income or expense in the period that includes the enactment date. We recognize the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. We file a consolidated U.S. federal income tax return which includes certain eligible subsidiaries. Non-U.S. subsidiaries and certain U.S. subsidiaries, which are consolidated for financial reporting purposes, are not eligible to be included in our consolidated U.S. federal income tax return. Separate provisions for income taxes have been determined for these entities. For unremitted earnings of our non-U.S. subsidiaries, we are required to make an assertion regarding reinvestment or repatriation for tax purposes. For any earnings that we do not make a permanent reinvestment assertion, we recognize a provision for deferred income taxes. For earnings where we have made a permanent reinvestment assertion, no provision is recognized. See Note 5 for further discussion. Comprehensive Income Comprehensive income includes net earnings adjusted for certain gains and losses that are excluded from net earnings under GAAP, which consists primarily of foreign currency translation adjustments. Foreign Currency Translation Assets and liabilities denominated in a foreign currency are translated into U.S. dollars at the current rate of exchange on the last day of the reporting period. Revenues and expenses are translated using average exchange rates for the period and equity transactions are translated using the actual rate on the day of the transaction. Recently Issued 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. ASU No. 2018-02 is effective for us in the first quarter of fiscal 2019 and early adoption is permitted. Two transition methods are available: at the beginning of the period of adoption, or retrospective to each period in which the income tax effects of the Tax Act related to items remaining in accumulated other comprehensive income are recognized. We are evaluating the effect that ASU No. 2018-02 will have on our consolidated financial statements and related disclosures. 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. ASU No. 2017-12 is effective for us in the first quarter of fiscal 2019. Early adoption is permitted in any interim period after issuance of this update. We are evaluating the effect that ASU No. 2017-12 will have on our consolidated financial statements and related disclosures. ASU No. 2017-04. In January 2017, the FASB issued ASU No. 2017-04, "Intangibles–Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment," which simplifies how an entity is required to test goodwill for impairment. The amendments in ASU No. 2017-04 require goodwill impairment to be measured using the difference between the carrying amount and the fair value of the reporting unit and require the loss recognized to not exceed the total amount of goodwill allocated to that reporting unit. ASU No. 2017-04 should be applied on a prospective basis and is effective for our annual goodwill impairment tests beginning in the first quarter of fiscal 2020. Early adoption is permitted. We have evaluated the effect that ASU No. 2017-04 will have on our consolidated financial statements and related disclosures and noted no material impact. ASU No. 2016-16. In October 2016, the FASB issued ASU No. 2016-16, "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory," which requires an entity to recognize the income tax consequences of an intercompany transfer of assets other than inventory when the transfer occurs. An entity will continue to recognize the income tax consequences of an intercompany transfer of inventory when the inventory is sold to a third party. ASU No. 2016-16 is effective for us in the first quarter of fiscal 2018 using a modified retrospective approach. We are evaluating the effect that ASU No. 2016-16 will have on our consolidated financial statements and related disclosures. ASU No. 2016-02. In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)," which requires an entity that is a lessee to recognize the assets and liabilities arising from leases on the balance sheet. ASU No. 2016-02 also requires disclosures about the amount, timing, and uncertainty of cash flows arising from leases. ASU No. 2016-02 is effective for us in the first quarter of fiscal 2019 using a modified retrospective approach. Early adoption is permitted. We are evaluating and planning for the adoption and implementation of ASU No. 2016-02. We believe that ASU No. 2016-02 will have a material impact on our financial position, as a result of the requirement to recognize right-of-use assets and lease liabilities on our consolidated balance sheets. The impact to our results of operations is being evaluated, and we do not believe there will be a material impact to our cash flows upon adoption of ASU No. 2016-02. ASU No. 2014-09. In May 2014, the FASB issued a new ASU related to revenue recognition. Under ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)," revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. In addition, ASU No. 2014-09 requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. ASU No. 2014-09 permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (modified retrospective method). ASU No. 2014-09 is effective for us in the first quarter of fiscal 2018. We will adopt ASU No. 2014-09 in the first quarter of fiscal 2018 using the modified retrospective method. This adoption will not materially impact our consolidated financial statements or related disclosures. Under ASU No. 2014-09, we will change the presentation of certain expenses and cost reimbursements associated with our PLCC program, certain expenses related to the sale of our gift cards to customers, and gift card breakage income. We will also change our recognition of gift card breakage income to be recognized proportionately as redemption occurs, rather than based on historical redemption patterns. We are in the process of implementing changes to our processes, controls and systems in support of our adoption of ASU No. 2014-09. Recent accounting pronouncements pending adoption not discussed above are either not applicable or are not expected to have a material impact on us.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements ASU No. 2016-09. In the first quarter of fiscal 2017, we adopted ASU No. 2016-09, "Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting." Upon adoption of this update, all excess tax benefits or deficiencies related to share-based payment awards are recognized in the provision for income taxes in the period in which they occur. Previously these amounts were reflected in paid-in capital. In addition, upon adoption, these amounts are classified as an operating activity in our consolidated statements of cash flows in the period in which they occur. Previously, these amounts were reflected as a financing activity. Cash paid to tax authorities when directly withholding shares for tax withholding purposes will continue to be classified as a financing activity in our consolidated statements of cash flows. Stock-based compensation expense will continue to reflect estimated forfeitures of share-based awards. We have adopted the applicable provisions of ASU No. 2016-09 prospectively. As a result of the adoption of ASU No. 2016-09, we recognized $106 million of excess tax benefits related to share-based payment awards in our provision for income taxes during fiscal 2017. The recognition of these benefits contributed $0.09 to diluted earnings per share in fiscal 2017.

All of our senior notes, other than our outstanding floating rate notes, may be redeemed by us at any time, in whole or in part, at the redemption price plus accrued interest up to the redemption date. The redemption price is equal to the greater of (1) 100% of the principal amount of the notes to be redeemed, or (2) the sum of the present values of the remaining scheduled payments of principal and interest to the Par Call Date, as defined in the respective notes. Additionally, if a Change in Control Triggering Event occurs, as defined in the notes, holders of all notes have the right to require us to redeem those notes at 101% of the aggregate principal amount of the notes plus accrued interest up to the redemption date. We are generally not limited under the indentures governing the notes in our ability to incur additional indebtedness or required to maintain financial ratios or specified levels of net worth or liquidity.

As a result of enactment of the Tax Act, our fiscal 2017 tax provision reflects additional net tax expense of $127 million . As part of the transition to the new territorial tax system, the Tax Act imposes a one-time tax on deemed repatriation of historical earnings of foreign subsidiaries. For fiscal 2017, these impacts resulted in a provisional charge in the fourth quarter of approximately $400 million , comprising U.S. repatriation taxes, foreign withholding taxes, and state taxes. The lower corporate income tax rate of 21% is effective January 1, 2018, resulting in a U.S. statutory federal tax rate of approximately 34% for fiscal 2017, and 21% for subsequent fiscal years, which provided a benefit to our fiscal 2017 tax provision of approximately $126 million . The reduction of the U.S. corporate tax rate requires a remeasurement of our U.S. deferred tax assets and liabilities to the lower federal base rate of 21% . This resulted in a provisional benefit of $147 million for fiscal 2017. The Tax Act also added a new provision for a tax on global intangible low-taxed income (“GILTI”). Due to the complexity of the new tax rules, we are considering available accounting policy alternatives to adopt, to either record the U.S. income tax effect of future GILTI inclusions in the period in which they arise or establish deferred taxes with respect to the expected future tax liabilities associated with future GILTI inclusions. We have not made an accounting policy election and will do so after we complete an analysis of those provisions. On December 22, 2017, the SEC issued Staff Accounting Bulletin No. 118 ("SAB 118") to address the application of GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Act. In accordance with SAB 118, we were able to make reasonable estimates of certain effects and, therefore, recorded provisional amounts for the remeasurement of deferred tax assets and liabilities and the tax on the mandatory deemed repatriation of foreign earnings. For the remeasurement of our deferred tax assets and liabilities, we have recorded a provisional benefit of $147 million for the year ended January 28, 2018. While we are able to make a reasonable estimate of the impact of the reduction in corporate rate, it may be affected by other factors, including, but not limited to, changes to our calculation of deemed repatriation of deferred foreign income and changes to the current year deferred tax balance estimates. To determine the amount of the income tax on mandatory deemed repatriation of foreign earnings, we must determine, in addition to other factors, the amount of post-1986 earnings and profits ("E&P") of the relevant subsidiaries, as well as the amount of non-U.S. income taxes paid on such earnings. We are able to make a reasonable estimate of the tax and recorded a provisional obligation of $400 million . However, we are continuing to gather additional information to more precisely compute the amount of the tax. We expect additional regulatory guidance and technical clarifications from the U.S. Department of the Treasury and IRS within the next 12 months. Any subsequent adjustment to these amounts will be recorded to income tax expense from continuing operations in the quarter of fiscal year 2018 in which the analysis is complete.

At January 28, 2018 , we had federal, state, and foreign net operating loss carryforwards available to reduce future taxable income, expiring at various dates beginning in 2018 to 2037 . We have concluded that it is more likely than not that the tax benefits related to the federal and state net operating losses will be realized. As of January 29, 2017 , a valuation allowance of $3 million had been provided to reduce the deferred tax asset related to foreign net operating losses to an amount that is more likely than not to be realized. As of January 28, 2018 , we are no longer active in the foreign jurisdictions in which the valuation allowance relates; therefore, the valuation allowance of $3 million was released this year when the related deferred tax asset was written off. We intend to reinvest substantially all of the unremitted earnings of our non-U.S. subsidiaries in excess of working capital and strategic requirements and postpone their remittance indefinitely. Accordingly, no provision for withholding taxes was recorded on these unremitted earnings in the accompanying consolidated statements of earnings. It is impracticable for us to determine the amount of unrecognized deferred tax liabilities on these indefinitely reinvested earnings. We have reevaluated our investment position with respect to certain cash balances and we do not intend to indefinitely reinvest cash in excess of working capital and strategic requirements. Accordingly, we have recorded a provisional deferred tax expense for these unremitted earnings in the accompanying consolidated statements of earnings. Our income tax returns are routinely examined by domestic and foreign tax authorities. For fiscal years 2005 through 2009 , a transfer pricing issue remains open pending negotiations between the U.S. and Mexican tax authorities. Our U.S. federal tax returns for fiscal years 2010 through 2012 are currently under examination by the IRS. During fiscal 2016, the IRS issued a proposed adjustment relating to transfer pricing between our entities in the U.S. and China for fiscal years 2010 through 2012 . We intend to defend our position using all available remedies including bi-lateral relief. There are also ongoing U.S. state and local and other foreign audits covering fiscal years 2005 through 2015 . We do not expect the results from any ongoing income tax audit to have a material impact on our consolidated financial condition, results of operations, or cash flows. Over the next twelve months, it is reasonably possible that the resolution of federal and state tax examinations could reduce our unrecognized tax benefits by $187 million . Final settlement of these audit issues may result in payments that are more or less than this amount, but we do not anticipate the resolution of these matters will result in a material change to our consolidated financial condition or results of operations.

We enter into ASR agreements from time to time with third-party financial institutions to repurchase shares of our common stock. Under an ASR agreement, we pay a specified amount to the financial institution and receive an initial delivery of shares. This initial delivery of shares represents the minimum number of shares that we may receive under the agreement. Upon settlement of the ASR agreement, the financial institution delivers additional shares, with the final number of shares delivered determined with reference to the volume weighted average price per share of our common stock over the term of the agreement, less a negotiated discount. The transactions are accounted for as equity transactions and are included in treasury stock when the shares are received, at which time there is an immediate reduction in the weighted average common shares calculation for basic and diluted earnings per share.

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS The fair value of an asset is considered to be the price at which the asset could be sold in an orderly transaction between unrelated knowledgeable and willing parties. A liability’s fair value is defined as the amount that would be paid to transfer the liability to a new obligor, rather than the amount that would be paid to settle the liability with the creditor. Assets and liabilities recorded at fair value are measured using a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis The carrying amounts of cash and cash equivalents, receivables, short-term debt, and accounts payable approximate fair value due to the short-term maturities of these financial instruments. Long-lived assets, goodwill, and other intangible assets were analyzed for impairment on a nonrecurring basis using fair value measurements with unobservable inputs (level 3). The estimated fair values of the assets acquired and liabilities assumed for Interline, which was acquired in the third quarter of fiscal 2015, were measured using unobservable inputs (level 3).

Amended and Restated 2005 Omnibus Stock Incentive Plan (the "2005 Plan") and The Home Depot, Inc. 1997 Omnibus Stock Incentive Plan (the "1997 Plan" and collectively with the 2005 Plan, the "Plans") provide that incentive and nonqualified stock options, stock appreciation rights, restricted stock, performance shares, performance units, and deferred shares may be issued to certain of our associates, officers, and directors. Under the 2005 Plan, the maximum number of shares of our common stock authorized for issuance is 255 million shares, with any award other than a stock option or stock appreciation right reducing the number of shares available for issuance by 2.11 shares. At January 28, 2018 , there were 130 million shares available for future grants under the 2005 Plan. No additional equity awards could be issued from the 1997 Plan after the adoption of the 2005 Plan on May 26, 2005. Stock Options. Under the terms of the Plans, incentive stock options and nonqualified stock options must have an exercise price at or above the fair market value of our stock on the date of the grant. Typically, incentive stock options and nonqualified stock options vest at the rate of 25% per year commencing on the first or second anniversary date of the grant, and expire on the tenth anniversary date of the grant.

Restricted Stock and Performance Shares. Restrictions on the restricted stock issued under the Plans generally lapse according to one of the following schedules: • the restrictions on the restricted stock lapse over various periods up to five years; • the restrictions on 25% of the restricted stock lapse upon the third and sixth anniversaries of the date of issuance with the remaining 50% of the restricted stock lapsing upon the associate’s attainment of age 62; or • the restrictions on 25% of the restricted stock lapse upon the third and sixth anniversaries of the date of issuance with the remaining 50% of the restricted stock lapsing upon the earlier of the associate’s attainment of age 60 or the tenth anniversary of the grant date. We have also granted performance shares under the Plans, the payout of which is dependent on our performance against target average ROIC and operating profit over a three-year performance cycle. Additionally, certain awards may become non-forfeitable upon the associate's attainment of age 60, provided the associate has had five years of continuous service.

We make cash contributions each payroll period up to specified percentages of associates’ contributions as approved by our Board of Directors. We also maintain the Restoration Plan to provide certain associates deferred compensation that they would have received under the Benefit Plans as a matching contribution if not for the maximum compensation limits under the Internal Revenue Code. We fund the Restoration Plan through contributions made to a grantor trust, which are then used to purchase shares of our common stock in the open market.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES At January 28, 2018 , we were contingently liable for approximately $447 million under outstanding letters of credit and open accounts issued for certain business transactions, including insurance programs, trade contracts, and construction contracts. Our letters of credit are primarily performance-based and are not based on changes in variable components, a liability or an equity security of the other party. In addition to the Data Breach described below, we are involved in litigation arising in the normal course of business. In management’s opinion, any such litigation is not expected to have a material adverse effect on our consolidated financial condition, results of operations, or cash flows. Data Breach As previously reported, in the third quarter of fiscal 2014, we confirmed that our payment data systems were breached, which potentially impacted customers who used payment cards at self-checkout systems in our U.S. and Canadian stores (the "Data Breach"). The Data Breach resulted in a number of claims and investigations, a significant number of which had been resolved prior to fiscal 2017. During fiscal 2017, the United States District Court for the Northern District of Georgia approved settlement agreements that resolved and dismissed the claims asserted in the two remaining litigation matters, the financial institution class actions and the purported shareholder derivative actions. We previously recorded accruals for estimated probable losses in connection with the matters described above. As of the end of fiscal 2017, we had resolved the consumer, financial institution, and shareholder derivative claims, representing the significant majority of the claims relating to the Data Breach, and there were no material changes during fiscal 2017 to our loss contingency assessment relating to any remaining matters. Further, we do not believe that the ultimate amounts to be paid with respect to any remaining matters will have a material adverse effect on our consolidated financial condition, results of operations, or cash flows in future periods. As a result, in future filings we do not anticipate providing separate reporting with respect to the Data Breach.

The aggregate purchase price was $1.7 billion , a portion of which was used for the repayment of substantially all of Interline’s indebtedness at that time. We have consolidated Interline’s results of operations in our financial statements since the date of acquisition. Pro forma results of operations for the period prior to the acquisition in fiscal 2015 would not be materially different as a result of the acquisition and therefore are not presented. We finalized our purchase price allocation during the fourth quarter of fiscal 2015.

Summary of Significant Accoun23

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Jan. 28, 2018
Accounting Policies [Abstract]
Business, Consolidation and Presentation	Our consolidated financial statements include our accounts and those of our wholly-owned subsidiaries. All significant intercompany transactions have been eliminated in consolidation.
Fiscal Year	Our fiscal year is a 52- or 53-week period ending on the Sunday nearest to January 31. Fiscal 2017, 2016, and 2015 each included 52 weeks.
Use of Estimates	We have made a number of estimates and assumptions relating to the reporting of assets and liabilities, the disclosure of contingent assets and liabilities, and reported amounts of revenues and expenses in preparing these financial statements in conformity with GAAP. Actual results could differ from these estimates.
Cash Equivalents	We consider all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. Our cash equivalents are carried at fair market value and consist primarily of money market funds.
Accounts Receivable	Card receivables consist of payments due from financial institutions for the settlement of credit card and debit card transactions. Rebate receivables represent amounts due from vendors for volume and co-op advertising rebates. Receivables due from customers relate to credit extended directly to customers by certain subsidiaries in the ordinary course of business.
Merchandise Inventories	The majority of our merchandise inventories are stated at the lower of cost (first-in, first-out) or market, as determined by the retail inventory method. As the inventory retail value is adjusted regularly to reflect market conditions, the inventory valued using the retail method approximates the lower of cost or market. Certain subsidiaries, including retail operations in Canada and Mexico, and distribution centers, record merchandise inventories at the lower of cost or market, as determined by a cost method. These merchandise inventories represent approximately 30% of the total merchandise inventories balance. We evaluate the inventory valued using a cost method at the end of each quarter to ensure that it is carried at the lower of cost or net realizable value. The valuation allowance for merchandise inventories valued under a cost method was not material to our consolidated financial statements at the end of fiscal 2017 or 2016 . Independent physical inventory counts or cycle counts are taken on a regular basis in each store and distribution center to ensure that amounts reflected in merchandise inventories are properly stated. Shrink (or in the case of excess inventory, "swell") is the difference between the recorded amount of inventory and the physical inventory. We calculate shrink based on actual inventory losses occurring as a result of physical inventory counts during each fiscal period and estimated inventory losses occurring between physical inventory counts. The estimate for shrink occurring in the interim period between physical inventory counts is calculated on a store-specific basis based on recent shrink results and current trends in the business.
Property and Equipment	Buildings, furniture, fixtures, and equipment are recorded at cost and depreciated using the straight-line method over their estimated useful lives. Leasehold improvements are amortized using the straight-line method over the original term of the lease or the useful life of the improvement, whichever is shorter.
Capitalized Software Costs	We capitalize certain costs related to the acquisition and development of software and amortize these costs using the straight-line method over the estimated useful life of the software, which is three to six years. Certain development costs not meeting the criteria for capitalization are expensed as incurred.
Goodwill and Other Intangible Assets	Goodwill represents the excess of purchase price over the fair value of net assets acquired. We do not amortize goodwill, but assess the recoverability of goodwill in the third quarter of each fiscal year, or more often if indicators warrant, by determining whether the fair value of each reporting unit supports its carrying value. Each fiscal year, we may assess qualitative factors to determine whether it is more likely than not that the fair value of each reporting unit is less than its carrying amount as a basis for determining whether it is necessary to complete quantitative impairment assessments, with a quantitative assessment completed at least once every three years.
Impairment of Long-Lived Assets	We evaluate our long-lived assets each quarter for indicators of potential impairment. Indicators of impairment include current period losses combined with a history of losses, our decision to relocate or close a store or other location before the end of its previously estimated useful life, or when changes in other circumstances indicate the carrying amount of an asset may not be recoverable. The evaluation for long-lived assets is performed at the lowest level of identifiable cash flows, which is generally the individual store level. The assets of a store with indicators of impairment are evaluated for recoverability by comparing its undiscounted future cash flows with its carrying value. If the carrying value is greater than the undiscounted future cash flows, we then measure the asset’s fair value to determine whether an impairment loss should be recognized. If the resulting fair value is less than the carrying value, an impairment loss is recognized for the difference between the carrying value and the estimated fair value. Impairment losses are recorded as a component of SG&A. When a leased location closes, we also recognize, in SG&A, the net present value of future lease obligations less estimated sublease income.
Debt	Any premiums or discounts, as the case may be, associated with an issuance of long-term debt are recorded as a direct addition or deduction to the carrying value of the related senior notes and amortized over the term of those notes using the effective interest rate method. Debt issuance costs associated with an issuance of long-term debt are recorded as a direct deduction to the carrying value of the related senior notes and amortized over the term of those notes using the effective interest rate method.
Derivatives	We use derivative financial instruments in the management of our interest rate exposure on long-term debt and our exposure to foreign currency fluctuations. For derivatives that are designated as hedges, changes in their fair values that are considered effective are either accounted for in earnings or recognized in other comprehensive income (loss) until the hedged item is recognized in earnings, depending on the nature of the hedge. Any ineffective portion of a derivative’s change in fair value is immediately recognized in earnings. Financial instruments that do not qualify for hedge accounting are recorded at fair value with unrealized gains or losses reported in earnings. All qualifying derivative financial instruments are recognized at their fair values in either assets or liabilities at the balance sheet date and are reported on a gross basis.
Insurance	We are self-insured for certain losses related to general liability (including product liability), workers’ compensation, employee group medical, and automobile claims. We recognize the expected ultimate cost for claims incurred (undiscounted) at the balance sheet date as a liability. The expected ultimate cost for claims incurred is estimated based upon analysis of historical data and actuarial estimates. We also maintain network security and privacy liability insurance coverage to limit our exposure to losses such as those that may be caused by a significant compromise or breach of our data security. Insurance related expenses are included in SG&A.
Treasury Stock	Treasury stock is reflected as a reduction of stockholders' equity at cost. We use the weighted-average purchase cost to determine the cost of treasury stock that is reissued.
Revenues	We also record deferred revenue for the sale of gift cards and recognize this revenue upon the redemption of gift cards in net sales. Gift card breakage income is recognized based upon historical redemption patterns and represents the balance of gift cards for which we believe the likelihood of redemption by the customer is remote. We recognize revenue, net of estimated returns and sales tax, at the time the customer takes possession of merchandise or when a service is performed. The liability for sales returns, including the impact to gross profit, is estimated based on historical return levels.
Services Revenue	Net sales include services revenue generated through a variety of installation, home maintenance, and professional service programs. In these programs, the customer selects and purchases material for a project, and we provide or arrange professional installation. These programs are offered through our stores and in-home sales programs. Under certain programs, when we provide or arrange the installation of a project and the subcontractor provides material as part of the installation, both the material and labor are included in services revenue. We recognize this revenue when the service for the customer is complete. When we receive payment from customers before the customer has taken possession of the merchandise or the service has been performed, the amount received is recorded as deferred revenue until the sale or service is complete.
Cost of Sales	Cost of sales includes the actual cost of merchandise sold and services performed; the cost of transportation of merchandise from vendors to our distribution network, stores, or customers; shipping and handling costs from our stores or distribution network to customers; the operating cost and depreciation of our sourcing and distribution network and online fulfillment centers; and the cost of deferred interest programs offered through our PLCC programs.
Cost of Credit	We have agreements with third-party service providers who directly extend credit to customers, manage our PLCC program, and own the related receivables. We have evaluated the third-party entities holding the receivables under the program and concluded that they should not be consolidated. The agreement with the primary third-party service provider for our PLCC program expires in 2028 , with us having the option, but no obligation, to purchase the receivables at the end of the agreement. The deferred interest charges we incur for our deferred financing programs offered to our customers are included in cost of sales. The interchange fees charged to us for our customers’ use of the cards and any profit sharing with the third-party service providers are included in SG&A. The sum of these three components is referred to as the cost of credit of the PLCC program.
Vendor Allowances	Vendor allowances primarily consist of volume rebates that are earned as a result of attaining certain purchase levels and co-op advertising allowances for the promotion of vendors’ products that are typically based on guaranteed minimum amounts with additional amounts being earned for attaining certain purchase levels. These vendor allowances are accrued as earned, with those allowances received as a result of attaining certain purchase levels accrued over the incentive period based on estimates of purchases. Volume rebates and certain co-op advertising allowances earned are initially recorded as a reduction in merchandise inventories and a subsequent reduction in cost of sales when the related product is sold.
Cooperative Advertising	Certain co-op advertising allowances that are reimbursements of specific, incremental, and identifiable costs incurred to promote vendors’ products are recorded as an offset against advertising expense in SG&A
Prepaid Advertising	Television and radio advertising production costs, along with media placement costs, are expensed when the advertisement first appears. Gross advertising expense is included in SG&A.
Income Taxes	Income taxes are accounted for under the asset and liability method. We provide for federal, state, and foreign income taxes currently payable, as well as for those deferred due to timing differences between reporting income and expenses for financial statement purposes versus tax purposes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted income tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in income tax rates is recognized as income or expense in the period that includes the enactment date. We recognize the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is greater than 50% likely of being realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs. We file a consolidated U.S. federal income tax return which includes certain eligible subsidiaries. Non-U.S. subsidiaries and certain U.S. subsidiaries, which are consolidated for financial reporting purposes, are not eligible to be included in our consolidated U.S. federal income tax return. Separate provisions for income taxes have been determined for these entities.
Comprehensive Income	Comprehensive income includes net earnings adjusted for certain gains and losses that are excluded from net earnings under GAAP, which consists primarily of foreign currency translation adjustments.
Foreign Currency Translation	Assets and liabilities denominated in a foreign currency are translated into U.S. dollars at the current rate of exchange on the last day of the reporting period. Revenues and expenses are translated using average exchange rates for the period and equity transactions are translated using the actual rate on the day of the transaction.
Recently Issued 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. ASU No. 2018-02 is effective for us in the first quarter of fiscal 2019 and early adoption is permitted. Two transition methods are available: at the beginning of the period of adoption, or retrospective to each period in which the income tax effects of the Tax Act related to items remaining in accumulated other comprehensive income are recognized. We are evaluating the effect that ASU No. 2018-02 will have on our consolidated financial statements and related disclosures. 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. ASU No. 2017-12 is effective for us in the first quarter of fiscal 2019. Early adoption is permitted in any interim period after issuance of this update. We are evaluating the effect that ASU No. 2017-12 will have on our consolidated financial statements and related disclosures. ASU No. 2017-04. In January 2017, the FASB issued ASU No. 2017-04, "Intangibles–Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment," which simplifies how an entity is required to test goodwill for impairment. The amendments in ASU No. 2017-04 require goodwill impairment to be measured using the difference between the carrying amount and the fair value of the reporting unit and require the loss recognized to not exceed the total amount of goodwill allocated to that reporting unit. ASU No. 2017-04 should be applied on a prospective basis and is effective for our annual goodwill impairment tests beginning in the first quarter of fiscal 2020. Early adoption is permitted. We have evaluated the effect that ASU No. 2017-04 will have on our consolidated financial statements and related disclosures and noted no material impact. ASU No. 2016-16. In October 2016, the FASB issued ASU No. 2016-16, "Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory," which requires an entity to recognize the income tax consequences of an intercompany transfer of assets other than inventory when the transfer occurs. An entity will continue to recognize the income tax consequences of an intercompany transfer of inventory when the inventory is sold to a third party. ASU No. 2016-16 is effective for us in the first quarter of fiscal 2018 using a modified retrospective approach. We are evaluating the effect that ASU No. 2016-16 will have on our consolidated financial statements and related disclosures. ASU No. 2016-02. In February 2016, the FASB issued ASU No. 2016-02, "Leases (Topic 842)," which requires an entity that is a lessee to recognize the assets and liabilities arising from leases on the balance sheet. ASU No. 2016-02 also requires disclosures about the amount, timing, and uncertainty of cash flows arising from leases. ASU No. 2016-02 is effective for us in the first quarter of fiscal 2019 using a modified retrospective approach. Early adoption is permitted. We are evaluating and planning for the adoption and implementation of ASU No. 2016-02. We believe that ASU No. 2016-02 will have a material impact on our financial position, as a result of the requirement to recognize right-of-use assets and lease liabilities on our consolidated balance sheets. The impact to our results of operations is being evaluated, and we do not believe there will be a material impact to our cash flows upon adoption of ASU No. 2016-02. ASU No. 2014-09. In May 2014, the FASB issued a new ASU related to revenue recognition. Under ASU No. 2014-09, "Revenue from Contracts with Customers (Topic 606)," revenue is recognized when a customer obtains control of promised goods or services in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. In addition, ASU No. 2014-09 requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. ASU No. 2014-09 permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (modified retrospective method). ASU No. 2014-09 is effective for us in the first quarter of fiscal 2018. We will adopt ASU No. 2014-09 in the first quarter of fiscal 2018 using the modified retrospective method. This adoption will not materially impact our consolidated financial statements or related disclosures. Under ASU No. 2014-09, we will change the presentation of certain expenses and cost reimbursements associated with our PLCC program, certain expenses related to the sale of our gift cards to customers, and gift card breakage income. We will also change our recognition of gift card breakage income to be recognized proportionately as redemption occurs, rather than based on historical redemption patterns. We are in the process of implementing changes to our processes, controls and systems in support of our adoption of ASU No. 2014-09.
