Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation The accompanying consolidated financial statements include the accounts of NVR, Inc. and its subsidiaries (“NVR”, the “Company”, "we", "us", or "our") and certain other entities in which the Company is deemed to be the primary beneficiary (see Notes 3 and 4 herein for additional information). All significant intercompany transactions have been eliminated in consolidation. Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Management continually evaluates the estimates used to prepare the consolidated financial statements and updates those estimates as necessary. In general, our estimates are based on historical experience, on information from third party professionals, and other various assumptions that are believed to be reasonable under the facts and circumstances. Actual results could differ materially from those estimates made by management. Cash and Cash Equivalents Cash and cash equivalents include short-term investments with original maturities of three months or less. Restricted Cash Homebuilding restricted cash was attributable to customer deposits for certain home sales. Mortgage banking restricted cash includes amounts collected from customers for loans in process and closed mortgage loans held for sale. At December 31, 2019 and 2018 , $281 and $320 , respectively, of cash related to a consolidated variable interest entity is included in homebuilding “Other assets” on the accompanying consolidated balance sheet. Homebuilding Inventory The carrying value of inventory is stated at the lower of cost or market value. Cost of lots and completed and uncompleted housing units represent the accumulated actual cost of the units. Field construction supervisors’ salaries and related direct overhead expenses are included in inventory costs. Interest costs are not capitalized into inventory, with the exception of land under development and joint venture investments, as applicable (see below). Upon settlement, the cost of the unit is expensed on a specific identification basis. Cost of building materials is determined on a first-in, first-out basis. Sold inventory is evaluated for impairment based on the contractual sales price compared to the total estimated cost to construct. Unsold inventory is evaluated for impairment by analyzing recent comparable sales prices within the applicable community compared to the costs incurred to date plus the expected costs to complete. Any calculated impairments are recorded immediately. Contract Land Deposits We purchase finished lots under fixed price lot purchase agreements (“Lot Purchase Agreements”) that require deposits that may be forfeited if we fail to perform under the contract. The deposits are in the form of cash or letters of credit in varying amounts and represent a percentage of the aggregate purchase price of the finished lots. We maintain an allowance for losses on contract land deposits that reflects our judgment of the present loss exposure in the existing contract land deposit portfolio at the end of the reporting period. To analyze contract land deposit impairments, we conduct a loss contingency analysis each quarter. In addition to considering market and economic conditions, we assess contract land deposit impairments on a community-by-community basis pursuant to the purchase contract terms, analyzing, as applicable, current sales absorption levels, recent sales’ direct profit, the dollar differential between the contractual purchase price and the current market price for lots, a developer’s performance, a developer’s financial ability or willingness to reduce lot prices to current market prices, if necessary, and the contract’s default status by either us or the developer along with an analysis of the expected outcome of any such default. Our analysis is focused on whether we can sell houses at an acceptable margin and sales pace in a particular community in the current market with which we are faced. Because we do not own the finished lots on which we have placed a contract land deposit, if the above analysis leads to a determination that we cannot sell homes at an acceptable margin and sales pace at the current contractual lot price, we then determine whether we will elect to default under the contract, forfeit the deposit and terminate the contract, or whether we will attempt to restructure the Lot Purchase Agreement, which may require us to forfeit the deposit to obtain contract concessions from a developer. We also assess whether impairment is present due to collectibility issues resulting from a developer’s non-performance because of financial or other conditions. For the year ended December 31, 2019 we recognized a net pre-tax recovery of $680 of contract land deposits previously determined to be unrecoverable. For the years ended December 31, 2018 and 2017 , we incurred net pre-tax charges of $5,115 and $1,238 , respectively, related to impairment of contract land deposits. The contract land deposit assets on the accompanying consolidated balance sheets are shown net of the allowance for losses of $27,572 and $29,216 at December 31, 2019 and 2018 , respectively. Land Under Development On a limited basis, we directly acquire raw parcels of land already zoned for its intended use to develop into finished lots. Land under development includes the land acquisition costs, direct improvement costs, capitalized interest, where applicable, and real estate taxes. Land under development, including the land under development held by our unconsolidated joint ventures and the related joint venture investments, is reviewed for potential write-downs when impairment indicators are present. In addition to considering market and economic conditions, we assess land under development impairments on a community-by-community basis, analyzing, as applicable, current sales absorption levels, recent sales’ direct profit, and the dollar differential between the projected fully-developed cost of the lots and the current market price for lots. If indicators of impairment are present for a community, we perform an analysis to determine if the undiscounted cash flows estimated to be generated by those assets are less than their carrying amounts, and if so, impairment charges are required to be recorded in an amount by which the carrying amount of the assets exceeds the fair value of such assets. Our determination of fair value is primarily based on discounting the estimated future cash flows at a rate commensurate with the inherent risks associated with the assets and related estimated cash flow streams. See Notes 4 and 5 for further discussion of joint venture investments and land under development, respectively. Property, Plant, and Equipment Property, plant, and equipment are carried at cost less accumulated depreciation and amortization. Depreciation is based on the estimated useful lives of the assets using the straight-line method. Model home furniture and fixtures are generally depreciated over a 2 -year period, office facilities and other equipment are depreciated over a period of 3 to 10 years and production facilities are depreciated over periods of 5 to 40 years . Intangible Assets On December 31, 2012, we acquired substantially all of the assets of Heartland Homes, Inc., which resulted in us recording finite-lived intangible assets and goodwill. We completed our annual assessment for impairment of goodwill and management determined that there was no impairment. As of December 31, 2019 and 2018 , finite-lived intangible assets, net of accumulated amortization, totaled $466 and $621 , respectively. The remaining finite-lived intangible assets will be amortized on a straight-line basis over 3 years. As of both December 31, 2019 and 2018 , the goodwill value was $441 . Finite-lived intangible assets and goodwill are included in homebuilding "Other assets" in the accompanying consolidated balance sheets. Warranty/Product Liability Reserves We establish warranty and product liability reserves ("Warranty Reserve") to provide for estimated future expenses as a result of construction and product defects, product recalls and litigation incidental to our homebuilding business. Liability estimates are determined based on management’s judgment considering such factors as historical experience, the likely current cost of corrective action, manufacturers’ and subcontractors’ participation in sharing the cost of corrective action, consultations with third party experts such as engineers, and discussions with our general counsel and outside counsel retained to handle specific product liability cases. Mortgage Repurchase Reserve, Mortgage Loans Held for Sale and Derivatives and Hedging Activities We originate several different loan products to our customers to finance the purchase of a home through our wholly-owned mortgage subsidiary, NVR Mortgage Finance, Inc. (“NVRM”). NVRM sells all of the loans it originates into the secondary market on a servicing released basis, typically within 30 days from closing. All of the loans that NVRM originates are underwritten to the standards and specifications of the ultimate investor. Those underwriting standards are typically equal to or more stringent than the underwriting standards required by Fannie Mae (“FNMA”), Ginnie Mae (“GNMA”), Freddie Mac ("FHLMC"), the Department of Veterans Affairs (“VA”) and the Federal Housing Administration (“FHA”). Insofar as NVRM underwrites its originated loans to those standards, NVRM bears no increased concentration of credit risk from the issuance of loans, except in certain limited instances where repurchases or early payment default occur. NVRM employs a quality control department to ensure that its underwriting controls are effectively operating, and further assesses the underwriting function as part of its assessment of internal controls over financial reporting. NVRM maintains a reserve for losses on mortgage loans originated that reflects our judgment of the present loss exposure in the loans that NVRM has originated and sold. The reserve is calculated based on an analysis of historical experience and exposure (see Note 16 herein for further information). Mortgage loans held for sale are recorded at fair value when closed, and thereafter are carried at the lower of cost or fair value, net of deferred origination costs, until sold. In the normal course of business, NVRM enters into contractual commitments to extend credit to buyers of single-family homes with fixed expiration dates. The commitments become effective when the borrowers “lock-in” a specified interest rate within time frames established by NVRM. All borrowers are evaluated for credit worthiness prior to the extension of the commitment. Market risk arises if interest rates move adversely between the time of the “lock-in” of rates by the borrower and the sale date of the loan to a broker/dealer. To mitigate the effect of the interest rate risk inherent in providing rate lock commitments to borrowers, NVRM enters into optional or mandatory delivery forward sale contracts to sell whole loans and mortgage-backed securities to broker/dealers. The forward sale contracts lock-in an interest rate and price for the sale of loans similar to the specific rate lock commitments. NVRM does not engage in speculative or trading derivative activities. Both the rate lock commitments to borrowers and the forward sale contracts to broker/dealers are undesignated derivatives, and, accordingly, are marked to fair value through earnings. At December 31, 2019 , there were contractual commitments to extend credit to borrowers aggregating $581,065 , and open forward delivery sale contracts aggregating $986,041 , which hedge both the rate lock loan commitments and closed loans held for sale (see Note 15 herein for a description of the Company’s fair value accounting). Earnings per Share The following weighted average shares and share equivalents were used to calculate basic and diluted earnings per share for the years ended December 31, 2019 , 2018 and 2017 : Year Ended December 31, 2019 2018 2017 Weighted average number of shares outstanding used to calculate basic EPS 3,641 3,631 3,733 Dilutive securities: Stock options and restricted share units 332 461 507 Weighted average number of shares and share equivalents outstanding used to calculate diluted EPS 3,973 4,092 4,240 The assumed proceeds used in the treasury method for calculating our diluted earnings per share includes the amount the employee must pay upon exercise and the amount of compensation cost attributed to future services not yet recognized. The following stock options issued under equity incentive plans were outstanding during the years ended December 31, 2019 , 2018 and 2017 , but were not included in the computation of diluted earnings per share because the effect would have been anti-dilutive. Year Ended December 31, 2019 2018 2017 Anti-dilutive securities 319 370 15 Revenues – Homebuilding Operations We build single-family detached homes, townhomes and condominium buildings, which generally are constructed on a pre-sold basis. Revenue is recognized on the settlement date at the contract sales price, when control is transferred to our customers. Our contract liabilities, consisting of deposits received from customers (“Handmoney”) on homes not settled, were $131,886 and $138,246 as of December 31, 2019 and 2018 , respectively. Substantially all Handmoney is recognized in revenue within twelve months of being received from customers. Our contract assets, consisting of prepaid sales compensation, totaled approximately $14,600 and $17,000 , as of December 31, 2019 and 2018 , respectively. These amounts are included in homebuilding “Other assets” on the accompanying consolidated balance sheets. Mortgage Banking Fees Mortgage banking fees include income earned by NVRM for originating mortgage loans, servicing mortgage loans held on an interim basis, title fees, gains and losses on the sale of mortgage loans and mortgage servicing and other activities incidental to mortgage banking. Mortgage banking fees are generally recognized after the loan has been sold to an unaffiliated, third party investor. Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted 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 on the deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. See Note 11 herein for discussion of the impact on the Company's deferred tax asset resulting from the enactment of the Tax Cuts and Jobs Act in December 2017. ASC 740-10, Income Taxes , provides that a tax benefit from an uncertain tax position may be recognized when it is more-likely-than-not (defined as a likelihood of more than 50%) that the position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits. If a tax position does not meet the more-likely-than-not recognition threshold, despite our belief that its filing position is supportable, the benefit of that tax position is not recognized in the statements of income. We recognize interest related to unrecognized tax benefits as a component of income tax expense. Based on our historical experience in dealing with various taxing authorities, we have found that it is the administrative practice of the taxing authorities to not seek penalties from us for the tax positions we have taken on our returns related to our unrecognized tax benefits. Therefore, we do not accrue penalties for the positions in which we have an unrecognized tax benefit. We recognize unrecognized tax benefits in the period that the uncertainty is eliminated by either affirmative agreement of the uncertain tax position by the applicable taxing authority, by expiration of the applicable statute of limitation, or by determination in accordance with certain states’ administrative practices that the uncertain tax position has been effectively settled (see Note 11 herein for further information). Financial Instruments Except as otherwise noted herein, we believe that the carrying value approximates the fair value of our financial instruments (see Note 15 herein for further information). Equity-Based Compensation We recognize equity-based compensation expense within its income statement for all share-based payment arrangements, which includes non-qualified stock options to purchase shares of NVR common stock ("Options") and restricted share units ("RSUs"). Compensation expense is based on the grant-date fair value of the Options and RSUs granted, and is recognized on a straight-line basis over the requisite service period for the entire award (from the date of grant through the period of the last separately vesting portion of the grant). Options and RSUs which are subject to a performance condition are treated as a separate award from the “service-only” Options and RSUs, and compensation expense is recognized when it becomes probable that the stated performance target will be achieved. We calculate the fair value of our Options, which are non-publicly traded, using the Black-Scholes option-pricing model. The grant date fair value of the RSUs is the closing price of our common stock on the day immediately preceding the date of grant. The reversal of compensation expense previously recognized for grants forfeited is recorded in the period in which the forfeiture occurs. Our equity-based compensation plans are accounted for as equity-classified awards (see Note 12 herein for further discussion of equity-based compensation plans). Comprehensive Income For the years ended December 31, 2019 , 2018 and 2017 , comprehensive income equaled net income; therefore, a separate statement of comprehensive income is not included in the accompanying consolidated financial statements. Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements Leases On January 1, 2019, we adopted ASU 2016-02, Leases (Topic 842) , which requires the recognition of our leases on the balance sheet as right-of-use ("ROU") assets and lease liabilities. We elected to adopt Topic 842 using the effective date transition method, which permits us to apply the new standard prospectively and present comparative years under legacy GAAP. In adoption of the standard, we also elected the following: • to apply the package of practical expedients during transition, under which we were not required to reassess as of the date of adoption (i) whether any of our contracts are or contain leases, (ii) the classifications of our leases, and (iii) any initial direct costs related to those leases. • to exclude leases with an initial lease term of 12 months or less from the recognition requirements under Topic 842. • to utilize the portfolio approach for certain office equipment leases, grouping leases by asset type which have similar lease terms and payment schedules. Upon adoption, on January 1, 2019 we recorded a lease liability of $85,516 and a ROU asset of $79,345 , which was recorded net of previously recognized straight-line operating lease adjustments on existing leases. The adoption of Topic 842 did not have an impact on our recognition of lease expense. See additional lease disclosures in Note 13. Recently Issued Accounting Pronouncements In June 2016, FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326) , which significantly changes the way impairment of financial assets is recognized. The standard will require immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets, which will generally result in earlier recognition of allowances for credit losses on loans and other financial instruments. The standard’s provisions will be applied as a cumulative-effect adjustment to beginning retained earnings as of the effective date. The standard is effective for us as of January 1, 2020. We do not believe that the adoption of this standard will have a material effect on our consolidated financial statements and related disclosures. In January 2017, FASB issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment . The standard’s objective is to simplify the subsequent measurement of goodwill by eliminating the second step from the goodwill impairment test. Under the amendments in the standard, an entity would perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. If the carrying amount of a reporting unit exceeds its fair value, an impairment charge would then be recognized, not to exceed the amount of goodwill allocated to that reporting unit. The standard is effective for us on January 1, 2020. We do not believe that the adoption of this standard will have a material effect on our consolidated financial statements and related disclosures.

Segment Reporting [Abstract]
Segment Information, Nature of Operations, and Certain Concentrations	Segment Information, Nature of Operations, and Certain Concentrations Our homebuilding operations primarily construct and sell single-family detached homes, townhomes and condominium buildings under three trade names: Ryan Homes, NVHomes and Heartland Homes. The Ryan Homes product is marketed primarily to first-time and first-time move-up buyers. Ryan Homes operates in thirty-two metropolitan areas located in Maryland, Virginia, Washington, D.C., West Virginia, Pennsylvania, New York, North Carolina, South Carolina, Florida, Ohio, New Jersey, Delaware, Indiana, Illinois and Tennessee. The NVHomes and Heartland Homes products are marketed primarily to move-up and luxury buyers. NVHomes operates in Delaware and the Washington, D.C., Baltimore, MD and Philadelphia, PA metropolitan areas. Heartland Homes operates in the Pittsburgh, PA metropolitan area. We derived approximately 27% and 11% of our 2019 homebuilding revenues from the Washington, D.C. and Baltimore, MD metropolitan areas, respectively. Our mortgage banking segment is a regional mortgage banking operation. Substantially all of the mortgage banking segment’s loan closing activity is for our homebuilding customers. Our mortgage banking business generates revenues primarily from origination fees, gains on sales of loans, and title fees. A substantial portion of our mortgage operations is conducted in the Washington, D.C. and Baltimore, MD metropolitan areas. The following disclosure includes four homebuilding reportable segments that aggregate geographically our homebuilding operating segments, and the mortgage banking operations presented as a single reportable segment. The homebuilding reportable segments are comprised of operating divisions in the following geographic areas: Mid Atlantic: Maryland, Virginia, West Virginia, Delaware and Washington, D.C. North East: New Jersey and Eastern Pennsylvania Mid East: New York, Ohio, Western Pennsylvania, Indiana and Illinois South East: North Carolina, South Carolina, Florida and Tennessee Homebuilding profit before tax includes all revenues and income generated from the sale of homes, less the cost of homes sold, selling, general and administrative expenses, and a corporate capital allocation charge. The corporate capital allocation charge is eliminated in consolidation and is based on the segment’s average net assets employed. The corporate capital allocation charged to the operating segment allows the Chief Operating Decision Maker (“CODM”) to determine whether the operating segment’s results are providing the desired rate of return after covering our cost of capital. In addition, certain assets including goodwill and intangible assets, and consolidation adjustments as discussed further below, are not allocated to the operating segments as those assets are neither included in the operating segment’s corporate capital allocation charge, nor in the CODM’s evaluation of the operating segment’s performance. We record charges on contract land deposits when it is determined that it is probable that recovery of the deposit is impaired. For segment reporting purposes, impairments on contract land deposits are charged to the operating segment upon the termination of a Lot Purchase Agreement with the developer, or the restructuring of a Lot Purchase Agreement resulting in the forfeiture of the deposit. Mortgage banking profit before tax consists of revenues generated from mortgage financing, title insurance and closing services, less the costs of such services and general and administrative costs. Mortgage banking operations are not charged a corporate capital allocation charge. In addition to the corporate capital allocation and contract land deposit impairments discussed above, the other reconciling items between segment profit and consolidated profit before tax include unallocated corporate overhead (including all management incentive compensation), equity-based compensation expense, consolidation adjustments and external corporate interest expense. Our overhead functions, such as accounting, treasury and human resources are centrally performed and the costs are not allocated to our operating segments. Consolidation adjustments consist of such items necessary to convert the reportable segments’ results, which are predominantly maintained on a cash basis, to a full accrual basis for external financial statement presentation purposes, and are not allocated to our operating segments. External corporate interest expense primarily consists of interest charges on our 3.95% Senior Notes due 2022 (the “Senior Notes”) and is not charged to the operating segments because the charges are included in the corporate capital allocation discussed above. Following are tables presenting segment revenues, profit before taxes, assets, interest income, interest expense, depreciation and amortization and expenditures for property and equipment, with reconciliations to the amounts reported for the consolidated enterprise, where applicable: Year Ended December 31, 2019 2018 2017 Revenues: Homebuilding Mid Atlantic $ 3,901,573 $ 3,893,358 $ 3,543,687 Homebuilding North East 514,804 580,726 517,141 Homebuilding Mid East 1,501,139 1,455,834 1,250,165 Homebuilding South East 1,303,328 1,074,386 864,528 Mortgage Banking 167,820 159,370 130,319 Consolidated revenues $ 7,388,664 $ 7,163,674 $ 6,305,840 Year Ended December 31, 2019 2018 2017 Profit before taxes: Homebuilding Mid Atlantic $ 478,537 $ 462,178 $ 398,494 Homebuilding North East 51,728 69,789 60,218 Homebuilding Mid East 173,374 175,134 149,639 Homebuilding South East 155,144 118,296 95,826 Mortgage Banking 105,292 93,462 73,959 Total segment profit 964,075 918,859 778,136 Reconciling items: Equity-based compensation expense (1) (78,532 ) (75,701 ) (44,562 ) Corporate capital allocation (2) 224,468 213,903 198,384 Unallocated corporate overhead (105,125 ) (89,973 ) (89,514 ) Consolidation adjustments and other 45,130 16,612 27,450 Corporate interest expense (24,221 ) (23,968 ) (22,983 ) Reconciling items sub-total 61,720 40,873 68,775 Consolidated profit before taxes $ 1,025,795 $ 959,732 $ 846,911 (1) The increase in equity-based compensation expense for the year ended December 31, 2018 was primarily attributable to the issuance of Options and RSUs in the second quarter of 2018.

Variable Interest Entities

Variable Interest Entities	12 Months Ended

Variable Interest Entity, Reporting Entity Involvement, Maximum Loss Exposure [Abstract]
Variable Interest Entities	Variable Interest Entities Lot Purchase Agreements We generally do not engage in the land development business. Instead, we typically acquire finished building lots at market prices from various development entities under Lot Purchase Agreements. The Lot Purchase Agreements require deposits that may be forfeited if we fail to perform under the Lot Purchase Agreements. The deposits required under the Lot Purchase Agreements are in the form of cash or letters of credit in varying amounts, and typically range up to 10% of the aggregate purchase price of the finished lots. We believe this lot acquisition strategy reduces the financial requirements and risks associated with direct land ownership and land development. We may, at our option, choose for any reason and at any time not to perform under these Lot Purchase Agreements by delivering notice of our intent not to acquire the finished lots under contract. Our sole legal obligation and economic loss for failure to perform under these Lot Purchase Agreements is limited to the amount of the deposit pursuant to the liquidated damage provisions contained within the Lot Purchase Agreements. None of the creditors of any of the development entities with which we enter Lot Purchase Agreements have recourse to our general credit. We generally do not have any specific performance obligations to purchase a certain number or any of the lots, nor do we guarantee completion of the development by the developer or guarantee any of the developers’ financial or other liabilities. We are not involved in the design or creation of the development entities from which we purchase lots under Lot Purchase Agreements. The developer’s equity holders have the power to direct 100% of the operating activities of the development entity. We have no voting rights in any of the development entities. The sole purpose of the development entity’s activities is to generate positive cash flow returns for the equity holders. Further, we do not share in any of the profit or loss generated by the project’s development. The profits and losses are passed directly to the developer’s equity holders. The deposit placed by us pursuant to the Lot Purchase Agreement is deemed to be a variable interest in the respective development entities. Those development entities are deemed to be variable interest entities (“VIE”). Therefore, the development entities with which we enter into Lot Purchase Agreements, including the joint venture limited liability corporations, discussed below, are evaluated for possible consolidation by us. An enterprise must consolidate a VIE when that enterprise has a controlling financial interest in the VIE. An enterprise is deemed to have a controlling financial interest if it has i) the power to direct the activities of a VIE that most significantly impact the entity’s economic performance, and ii) the obligation to absorb losses of the VIE that could be significant to the VIE or the rights to receive benefits from the VIE that could be significant to the VIE. We believe the activities that most significantly impact a development entity’s economic performance are the operating activities of the entity. Unless and until a development entity completes finished building lots through the development process to be able to sell, the process of which the development entity’s equity investors bear the full risk, the entity does not earn any revenues. The operating development activities are managed solely by the development entity’s equity investors. The development entities with which we contract to buy finished lots typically select the respective projects, obtain the necessary zoning approvals, obtain the financing required with no support or guarantees from us, select who will purchase the finished lots and at what price, and manage the completion of the infrastructure improvements, all for the purpose of generating a cash flow return to the development entity’s equity holders and all independent of us. We possess no more than limited protective legal rights through the Lot Purchase Agreement in the specific finished lots that we are purchasing, and we possess no participative rights in the development entities. Accordingly, we do not have the power to direct the activities of a developer that most significantly impact the developer’s economic performance. For this reason, we concluded that we are not the primary beneficiary of the development entities with which we enter into Lot Purchase Agreements, and therefore we do not consolidate any of these VIEs. As of December 31, 2019 , we controlled approximately 101,300 lots under Lot Purchase Agreements with third parties through deposits in cash and letters of credit totaling approximately $439,500 and $5,500 , respectively. As noted above, our sole legal obligation and economic loss for failure to perform under these Lot Purchase Agreements is limited to the amount of the deposit pursuant to the liquidated damage provisions contained in the Lot Purchase Agreements and, in very limited circumstances, specific performance obligations. In addition, we have certain properties under contract with land owners that are expected to yield approximately 7,000 lots, which are not included in the number of total lots controlled. Some of these properties may require rezoning or other approvals to achieve the expected yield. These properties are controlled with deposits in cash and letters of credit totaling approximately $1,900 and $100 , respectively, as of December 31, 2019 , of which approximately $900 is refundable if we do not perform under the contract. We generally expect to assign the raw land contracts to a land developer and simultaneously enter into a Lot Purchase Agreement with the assignee if the project is determined to be feasible. Our total risk of loss related to contract land deposits as of December 31, 2019 and 2018 was as follows: December 31, 2019 2018 Contract land deposits $ 441,423 $ 425,393 Loss reserve on contract land deposits (27,572 ) (29,216 ) Contract land deposits, net 413,851 396,177 Contingent obligations in the form of letters of credit 5,606 3,923 Contingent specific performance obligations (1) — 1,505 Total risk of loss $ 419,457 $ 401,605 (1) As of December 31, 2019 , we had no specific performance obligations related to purchase of finished lots. As of December 31, 2018 , we were committed to purchase 10 finished lots under specific performance obligations.

Joint Ventures

Joint Ventures	12 Months Ended

Equity Method Investments and Joint Ventures [Abstract]
Joint Ventures	Joint Ventures On a limited basis, we obtain finished lots using joint venture limited liability corporations (“JVs”). The JVs are typically structured such that we are a non-controlling member and at risk only for the amount we have invested, or committed to invest, in addition to any deposits placed under Lot Purchase Agreements with the joint venture. We are not a borrower, guarantor or obligor on any debt of the JVs, as applicable. We enter into a standard Lot Purchase Agreement to purchase lots from these JVs, and as a result have a variable interest in these JVs. At December 31, 2019 , we had an aggregate investment totaling approximately $26,700 in five JVs that are expected to produce approximately 6,300 finished lots, of which approximately 2,950 lots were controlled by us and the remaining approximately 3,350 lots were either under contract with unrelated parties or not currently under contract. In addition, we had additional funding commitments in the aggregate totaling $4,300 to two of the JVs at December 31, 2019 . We determined that we are not the primary beneficiary of four of the JVs because we and the other JV partner either share power or the other JV partner has the controlling financial interest. The aggregate investment in unconsolidated JVs was approximately $26,700 and $29,400 at December 31, 2019 and 2018 , respectively, and is reported in the “Other assets” line item on the accompanying consolidated balance sheets. For the remaining JV, we concluded that we are the primary beneficiary because we have the controlling financial interest in the JV. As of December 31, 2018 , all activities under the consolidated JV had been completed. As of December 31, 2019 , we had no remaining investment in the JV and the JV had remaining balances of $281 in cash and $251 in accrued expenses, which are included in homebuilding "Other assets" and "Accrued expenses and other liabilities," respectively, in the accompanying consolidated balance sheets. At December 31, 2018 , we had an aggregate investment totaling approximately $29,400 in six JVs that were expected to produce approximately 6,800 finished lots, of which approximately 3,450 lots were controlled by us and the remaining approximately 3,350 lots were either under contract with unrelated parties or not currently under contract. In addition, at December 31, 2018 , we had additional funding commitments in the aggregate totaling $5,000 to three of the JVs. During 2018 , we recognized an impairment of approximately $7,400 , including approximately $760 of capitalized interest, related to one of the JVs. The charge was recorded to homebuilding "Cost of sales" on the accompanying consolidated statements of income. With our adoption of ASU 2016-15

We also have additional funding commitments of approximately $6,100 under a joint development agreement related to one parcel, a portion of which we expect will be offset by development credits of approximately $2,800 . None of the raw parcels had any indicators of impairment as of December 31, 2019 . As of December 31, 2018 , we directly owned three separate raw parcels of land with a carrying value of $38,857 , which were expected to produce approximately 500 finished lots.

Capitalized Interest	Capitalized Interest We capitalize interest costs to land under development during the active development of finished lots. In addition, we capitalize interest costs to our joint venture investments while the investments are considered qualified assets pursuant to ASC 835-20, Interest . Capitalized interest is transferred to sold or unsold inventory as the development of finished lots is completed, then charged to cost of sales upon our settlement of homes and the respective lots. Interest incurred in excess of the interest capitalizable based on the level of qualified assets is expensed in the period incurred. Our interest costs incurred, capitalized, expensed and charged to cost of sales during the years ended December 31, 2019 , 2018 and 2017 was as follows: December 31, 2019 2018 2017 Interest capitalized, beginning of year $ 4,154 $ 5,583 $ 5,106 Interest incurred 26,463 26,277 26,384 Interest charged to interest expense (25,380 ) (25,081 ) (24,185 ) Interest charged to cost of sales (1,738 ) (2,625 ) (1,722 ) Interest capitalized, end of year $ 3,499 $ 4,154 $ 5,583

Related Party Transactions	Related Party Transactions During the year ended December 31, 2019 , we entered into Lot Purchase Agreements to purchase finished building lots for a total purchase price of approximately $100,600 with Elm Street Development, Inc. (“Elm Street”), which is controlled by one of our directors, William Moran. The independent members of our Board of Directors approved these transactions. During 2019 , 2018 and 2017 , we purchased developed lots at market prices from Elm Street for approximately $44,600 , $36,100 and $37,100 , respectively. We also continue to control a parcel of raw land expected to yield approximately 2,200 finished lots through a JV entered into with Elm Street during 2009. We did not make any investments in the JV in 2019 or 2018 . During 2017, we and Elm Street each made an additional investment of $2,900

Debt Disclosure [Abstract]
Debt	Debt Senior Notes On September 10, 2012 , we completed an offering for $600,000 of Senior Notes under a shelf registration statement filed on September 5, 2012 with the Securities and Exchange Commission. The Senior Notes were issued at a discount to yield 3.97% and have been reflected net of the unamortized discount in the accompanying consolidated balance sheet. The offering of the Senior Notes resulted in aggregate net proceeds of approximately $593,900 , after deducting underwriting discounts and other offering expenses. The Senior Notes mature on September 15, 2022 and bear interest at 3.95% , payable semi-annually in arrears on March 15 and September 15 . The Senior Notes have been reflected net of unamortized debt issuance costs of $1,377 and $1,886 as of December 31, 2019 and 2018 , respectively. The Senior Notes are senior unsecured obligations and rank equally in right of payment with any of our existing and future unsecured senior indebtedness, will rank senior in right of payment to any of our future indebtedness that is by its terms expressly subordinated to the Senior Notes and will be effectively subordinated to any of our existing and future secured indebtedness to the extent of the value of the collateral securing such indebtedness. The indenture governing the Senior Notes has, among other items, and subject to certain exceptions, covenants that restrict our ability to create, incur, assume or guarantee secured debt, enter into sale and leaseback transactions and conditions related to mergers and/or the sale of assets. We were in compliance with all covenants under the Senior Notes at December 31, 2019 . Credit Agreement On July 15, 2016, we entered into an unsecured Credit Agreement (the “Credit Agreement”) with Bank of America, N.A., as Administrative Agent, Swing Line Lender and L/C Issuer, Merrill Lynch, Pierce, Fenner & Smith Incorporated as Sole Lead Arranger and Sole Book Runner, and the other lenders party thereto, which provides for aggregate revolving loan commitments of $200,000 (the “Facility”). Proceeds of the borrowings under the Facility will be used for working capital and general corporate purposes. Under the Credit Agreement, we may request increases of up to $300,000 to the Facility in the form of revolving loan commitments or term loans to the extent that new or existing lenders agree to provide additional revolving loan or term loan commitments. The Credit Agreement provides for a $100,000 sublimit for the issuance of letters of credit of which approximately $9,700 was outstanding at December 31, 2019 , and a $25,000 sublimit for a swing line commitment. Borrowings under the Credit Agreement generally bear interest for Base Rate Loans at a Base Rate equal to the highest of (i) a Federal Funds Rate plus one-half of one percent, (ii) Bank of America’s publicly announced “prime rate,” and (iii) the Eurodollar Rate plus one percent, plus the Applicable Rate which is based on the Company’s debt rating, or for Eurodollar Rate Loans, at the Eurodollar Rate equal to LIBOR plus the Applicable Rate. The Credit Agreement contains various representations and affirmative and negative covenants that are generally customary for credit facilities of this type. Such covenants include, among others, the following financial maintenance covenants: (i) minimum consolidated tangible net worth, (ii) minimum interest coverage ratio or minimum liquidity and (iii) a maximum leverage ratio. The negative covenants include, among others, certain limitations on liens, investments and fundamental changes. The Credit Agreement termination date is July 15, 2021 . We were in compliance with all covenants under the Credit Agreement at December 31, 2019 . There was no debt outstanding under the Facility at December 31, 2019 . Repurchase Agreement On July 24, 2019, NVRM entered into the Eleventh Amendment (the “Amendment”) to its Amended and Restated Master Repurchase Agreement dated August 2, 2011 with U.S. Bank National Association (as amended by the Amendment and ten earlier amendments, the “Repurchase Agreement”). The purpose of the Repurchase Agreement is to finance the origination of mortgage loans by NVRM. The Repurchase Agreement provides for loan purchases up to $150,000 , subject to certain sub limits. Advances under the Repurchase Agreement carry a Pricing Rate based on the LIBOR Rate plus the LIBOR Margin, as determined under the Repurchase Agreement, provided that the Pricing Rate shall not be less than 1.85% . The Pricing Rate at December 31, 2019 was 3.663% . There are several restrictions on purchased loans, including that they cannot be sold to others, they cannot be pledged to anyone other than the agent, and they cannot support any other borrowing or repurchase agreement. Amounts outstanding under the Repurchase Agreement are collateralized by our mortgage loans held for sale. At December 31, 2019 , there were no borrowing base limitations reducing the amount available under the Repurchase Agreement. As of both December 31, 2019 and 2018 , there was no debt outstanding under the Repurchase Agreement. The Repurchase Agreement expires on July 22, 2020 . The Repurchase Agreement contains various affirmative and negative covenants. The negative covenants include, among others, certain limitations on transactions involving acquisitions, mergers, the incurrence of debt, sale of assets and creation of liens upon any of its Mortgage Notes. Additional covenants include (i) a tangible net worth requirement, (ii) a minimum liquidity requirement, (iii) a minimum net income requirement, and (iv) a maximum leverage ratio requirement. NVRM was in compliance with all covenants under the Repurchase Agreement at December 31, 2019 .

Management believes that we will have sufficient future taxable income to make it more likely than not that the net deferred tax assets will be realized. Federal taxable income is estimated to be approximately $638,723 for the year ended December 31, 2019 , and was $640,195 for the year ended December 31, 2018 . A reconciliation of income taxes computed at the federal statutory rate ( 21% in 2019 and 2018, 35% in 2017) to income tax expense is as follows: Year Ended December 31, 2019 2018 2017 Income taxes computed at the federal statutory rate $ 215,417 $ 201,544 $ 296,419 State income taxes, net of federal income tax benefit (1) 45,770 42,944 30,046 Excess tax benefits from equity-based compensation (101,466 ) (77,478 ) (58,681 ) Remeasurement of net deferred tax assets due to enactment of Tax Cut and Jobs Act — (497 ) 62,702 Other, net (2) (12,465 ) (3,978 ) (21,096 ) Income tax expense $ 147,256 $ 162,535 $ 309,390 (1) Excludes state excess tax benefits from equity-based compensation included in the line below. (2) Primarily attributable to tax benefits from certain energy tax credits for the years ended December 31, 2019 and 2018. In 2019, the energy credit recorded related to homes we settled in both 2018 and 2019 due to the retroactive reinstatement of certain expired energy tax credits under the The Further Consolidated Appropriations Act. In 2018, the energy tax credits resulted from credit adjustments related to 2017 home settlement activity. For the year ended December 31, 2017, the tax benefit resulted primarily from the domestic production activities deduction, which was eliminated effective January 1, 2018, following the enactment of the Tax Cuts and Jobs Act in December 2017. Our effective tax rate in 2019 , 2018 and 2017 was 14.36% , 16.94% and 36.53% , respectively. We file a consolidated U.S. federal income tax return, as well as state and local tax returns in all jurisdictions where we maintain operations. With few exceptions, we are no longer subject to income tax examinations by tax authorities for years prior to 2016 . A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows: Year Ended December 31, 2019 2018 Balance at beginning of year $ 43,418 $ 45,337 Additions based on tax positions related to the current year 2,941 4,340 Reductions for tax positions of prior years (7,003 ) (6,259 ) Settlements — — Balance at end of year $ 39,356 $ 43,418 If recognized, the total amount of unrecognized tax benefits that would affect the effective tax rate (net of the federal tax benefit) is $31,090 as of December 31, 2019 . We recognize interest related to unrecognized tax benefits as a component of income tax expense. For the years ended December 31, 2019 , 2018 , and 2017 , we recognized a net reversal of accrued interest on unrecognized tax benefits in the amount of $1,467 , $1,384 and $1,065 , respectively. As of December 31, 2019 and 2018 , we had a total of $15,724 and $17,191 , respectively, of accrued interest on unrecognized tax benefits which are included in “Accrued expenses and other liabilities” on the accompanying consolidated balance sheets. We believe that within the next 12 months, it is reasonably possible that the unrecognized tax benefits as of December 31, 2019 will be reduced by approximately $6,951

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Equity-Based Compensation, Profit Sharing and Deferred Compensation Plans	Equity-Based Compensation, Profit Sharing and Deferred Compensation Plans Equity-Based Compensation Plans Our equity-based compensation plans provide for the granting of Options and RSUs to key management employees, including executive officers and members of our Board of Directors ("Directors"). The exercise price of Options granted is equal to the closing price of our common stock on the New York Stock Exchange (the “NYSE”) on the day prior to the date of grant. Options are granted for a 10 -year term and typically vest in separate tranches over periods of 3 to 6 years . RSUs generally vest in separate tranches over periods of 2 to 6 years . Grants are generally divided such that vesting for 50% of the grant is contingent solely on continued employment or service as a Director, while vesting for the remaining 50% of the grant is contingent upon both continued employment or service as a Director and the achievement of a performance metric based on our return on capital performance relative to a peer group during a 3 -year period specified on the date of grant. The following table provides a summary of each of our equity-based compensation plans with grants outstanding at December 31, 2019 : Equity-Based Compensation Plans Shares Authorized Options/RSUs Outstanding Shares Available to Issue 2000 Broadly-Based Stock Option Plan 2,000 11 — 2010 Equity Incentive Plan (1) 700 109 6 2014 Equity Incentive Plan (2) 950 514 137 2018 Equity Incentive Plan (3) 275 131 144 (1) During 2010, our shareholders approved the 2010 Equity Incentive Plan (the “2010 Plan”). The 2010 Plan authorizes us to issue Options and RSUs to key management employees, including executive officers and Directors. Of the 700 aggregate shares authorized to issue, up to 218 were available to grant in the form of RSUs. There were 94 Options and 15 RSUs outstanding as of December 31, 2019 . None of the remaining shares available to be issued under the 2010 Plan may be granted as RSUs. (2) During 2014, our shareholders approved the 2014 Equity Incentive Plan (the “2014 Plan”). The 2014 Plan authorizes us to issue Options to key management employees, including executive officers and Directors. (3) During 2018, our shareholders approved the 2018 Equity Incentive Plan (the "2018 Plan"). The 2018 Plan authorizes us to issue Options and RSUs to key management employees, including executive officers and Directors. Of the 275 aggregate shares authorized to issue, all may be granted in the form of Options and up to 40 may be granted in the form of RSUs. None of the grants outstanding as of December 31, 2019 have been granted in the form of RSUs. During 2019 , we issued 26 Options and 1 RSUs under the following equity-based compensation plans: 2010 Plan 2014 Plan Options Granted Options (4) 13 — Performance-based Options (5) 12 1 Total Options Granted 25 1 RSUs Granted RSUs (6) 1 — Performance-based RSUs — — Total RSUs Granted 1 — (4) Options granted vest over four years in 25% increments on beginning on either December 31, 2021 or December 31, 2022, based on the date of grant. Vesting for the Options is contingent solely upon continued employment or continued service as a Director. (5) Options granted vest over four years in 25% increments beginning on either December 31, 2021 or December 31, 2022, based on the date of grant. Vesting for the performance-based Options is contingent upon both continued employment or continued service as a Director and our return on capital performance during the three year periods beginning 2019 or 2020, based on the grant's vesting period. (6) Service-only RSUs granted vest over two years in 50% increments on January 28, 2020 and 2021. Vesting for the RSUs is contingent solely upon continued employment. The following table provides additional information relative to our equity-based compensation plans for the year ended December 31, 2019 : Shares Weighted Avg. Per Share Exercise Price Weighted Avg. Remaining Contract Life (years) Aggregate Intrinsic Value Stock Options Outstanding at December 31, 2018 1,049 $ 1,766.87 Granted 26 2,778.19 Exercised (271 ) 1,010.52 Forfeited (55 ) 2,377.25 Outstanding at December 31, 2019 749 $ 2,030.42 6.3 $ 1,331,593 Exercisable at December 31, 2019 353 $ 1,122.70 4.3 $ 946,842 RSUs Outstanding at December 31, 2018 21 Granted 1 Vested (5 ) Forfeited (2 ) Outstanding at December 31, 2019 15 $ 58,528 Vested, but not issued at December 31, 2019 — $ — To estimate the grant-date fair value of our Options, we use the Black-Scholes option-pricing model (the “Pricing Model”). The Pricing Model estimates the per share fair value of an option on its date of grant based on the following factors: the option’s exercise price; the price of the underlying stock on the date of grant; the estimated dividend yield; a risk-free interest rate; the estimated option term; and the expected volatility. For the risk-free interest rate, we use U.S. Treasury STRIPS which mature at approximately the same time as the option’s expected holding term. For expected volatility, we have concluded that our historical volatility over the option’s expected holding term provides the most reasonable basis for this estimate. The fair value of the Options granted during 2019 , 2018 and 2017 was estimated on the grant date using the Pricing Model, based on the following assumptions: 2019 2018 2017 Estimated option life (years) 5.55 5.06 5.26 Risk free interest rate (range) 1.51%-2.73% 2.19%-3.13% 1.53%-2.38% Expected volatility (range) 19.17%-22.01% 16.57%-20.05% 15.09%-17.95% Expected dividend rate — % — % — % Weighted average grant-date fair value per share of options granted $ 661.01 $ 687.81 $ 494.17 The grant date fair value per share of $2,517.06 for the RSUs was the closing price of our common stock on the day immediately preceding the date of grant. Compensation cost for Options and RSUs is recognized on a straight-line basis over the requisite service period for the entire award (from the date of grant through the period of the last separately vesting portion of the grant). For the recognition of equity-based compensation, the Options and RSUs which are subject to a performance condition are treated as a separate award from the “service-only” Options and RSUs, and compensation expense is recognized when it becomes probable that the stated performance target will be achieved. We currently believe that it is probable that the stated performance condition will be satisfied at the target level and are recognizing compensation expense related to such Options and RSUs accordingly. Compensation cost is recognized within the income statement in the same expense line as the cash compensation paid to the respective employees. We recognize forfeitures of equity-based awards as a reduction to compensation costs in the period in which they occur. In 2019 , 2018 and 2017 , we recognized $78,532 , $75,701 , and $44,562 in equity-based compensation costs, respectively, and approximately $16,800 , $17,200 , and $17,100 in tax benefit related to equity-based compensation costs, respectively. As of December 31, 2019 , the total unrecognized compensation cost for all outstanding Options and RSUs equaled approximately $209,000 . The unrecognized compensation cost will be recognized over each grant’s applicable vesting period with the latest vesting date being December 31, 2025. The weighted-average period over which the unrecognized compensation will be recorded is equal to approximately 2.4 years. We settle Option exercises and vesting of RSUs by issuing shares of treasury stock. Shares are relieved from the treasury account based on the weighted average cost of treasury shares acquired. During the years ended December 31, 2019 , 2018 and 2017 , we issued 276 , 188 and 165 shares, respectively, from the treasury account for Option exercises and vesting of RSUs. Information with respect to the vested RSUs and exercised Options is as follows: Year Ended December 31, 2019 2018 2017 Aggregate exercise proceeds $ 274,028 $ 174,110 $ 140,525 Aggregate intrinsic value on exercise dates $ 593,162 $ 355,318 $ 206,890 Profit Sharing Plans We have a trustee-administered, profit sharing retirement plan (the “Profit Sharing Plan”) and an Employee Stock Ownership Plan (“ESOP”) covering substantially all employees. The Profit Sharing Plan and the ESOP provide for annual discretionary contributions in amounts as determined by our Directors. The combined plan contribution for the years ended December 31, 2019 , 2018 and 2017 was approximately $20,300 , $19,500 and $16,700 , respectively. The ESOP purchased approximately 5 and 7 shares of our common stock in the open market for the 2019 and 2018 plan year contributions, respectively, using cash contributions provided by the Company. As of December 31, 2019 , all shares held by the ESOP had been allocated to participants’ accounts. The 2019 plan year contribution was funded and fully allocated to participants in February 2020 . Deferred Compensation Plans We have two deferred compensation plans (“Deferred Comp Plans”). The specific purpose of the Deferred Comp Plans is to i) establish a vehicle whereby named executive officers may defer the receipt of salary and bonus that otherwise would be nondeductible for Company tax purposes into a period where we would realize a tax deduction for the amounts paid, and ii) to enable certain employees who are subject to our stock holding requirements to acquire shares of our common stock on a pre-tax basis in order to more quickly meet, and maintain compliance with those stock holding requirements. Amounts deferred into the Deferred Comp Plans are invested in our common stock, held in a rabbi trust account, and are paid out in a fixed number of shares upon expiration of the deferral period. The rabbi trust account held 107 shares of NVR common stock as of both December 31, 2019 and 2018 . Shares held by the Deferred Comp Plans are treated as outstanding shares in our earnings per share calculation for each of the years ended December 31, 2019 , 2018 and 2017 .

Lessee, Operating Leases [Text Block]	Leases We have operating leases for our corporate and division offices, production facilities, model homes, and certain office and production equipment. Additionally, we have finance leases for production equipment which are recorded in homebuilding "Property, plant and equipment, net" and "Accrued expenses and other liabilities" on the accompanying consolidated balance sheets. Our leases have remaining lease terms of up to 20 years, some of which include options to extend the leases for up to 10 years, and some of which include options to terminate the lease. On January 1, 2019, we adopted ASU 2016-02, Leases (Topic 842), which requires lessees to recognize most leases on the balance sheet as ROU assets with corresponding lease liabilities. See Note 1 for additional discussion regarding the adoption of Topic 842. The ROU assets and lease liabilities are recognized based on the present value of lease payments over the lease term, discounted using our incremental borrowing rate at the commencement date of the lease. We estimate our incremental borrowing rate based on available published borrowing rates commensurate with our debt rating and the lease term, adjusted to infer collateralization. We recognize operating lease expense on a straight-line basis over the lease term. We have elected to use the portfolio approach for certain equipment leases which have similar lease terms and payment schedules. Additionally, for certain equipment we account for the lease and non-lease components as a single lease component. Our sublease income is de minimis. We have certain leases, primarily the leases of model homes, which have initial lease terms of twelve months or less ("Short-term leases"). We elected to exclude these leases from the recognition requirements under Topic 842, and these leases have not been included in our recognized ROU assets and lease liabilities.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments and Contingent Liabilities Litigation We are involved in various litigation arising in the ordinary course of business. In the opinion of management, and based on advice of legal counsel, this litigation is not expected to have a material adverse effect on our financial position, results of operations or cash flows. Legal costs incurred in connection with outstanding litigation are expensed as incurred. Contract Land Deposits We generally do not engage in the land development business. Instead, we typically acquire finished building lots at market prices from various development entities under Lot Purchase Agreements. The Lot Purchase Agreements require deposits that may be forfeited if we fail to perform under the agreement. The deposits required under the Lot Purchase Agreements are in the form of cash or letters of credit in varying amounts, and typically range up to 10% of the aggregate purchase price of the finished lots. At December 31, 2019 , assuming that contractual development milestones are met and we exercise our option,we expect to place additional forfeitable deposits with land developers under existing Lot Purchase Agreements of approximately $211,500 . Additionally, as of December 31, 2019 , we had funding commitments totaling approximately $6,100 under a joint development agreement related to our land under development, a portion of which we expect will be offset by development credits of approximately $2,800 . Bonds and Letters of Credit During the ordinary course of operating the homebuilding and mortgage banking businesses, we are required to enter into bond or letter of credit arrangements with local municipalities, government agencies, or land developers to collateralize our obligations under various contracts. We had approximately $40,600 of contingent obligations under such agreements, including approximately $9,700 for letters of credit issued under the Credit Agreement as of December 31, 2019 . We believe we will fulfill our obligations under the related contracts and does not anticipate any material losses under these bonds or letters of credit. Warranty Reserve The following table reflects the changes in our Warranty Reserve (see Note 1 herein for further discussion of warranty/product liability reserves): Year Ended December 31, 2019 2018 2017 Warranty reserve, beginning of year $ 103,700 $ 94,513 $ 93,895 Provision 69,065 62,553 44,652 Payments (64,712 ) (53,366 ) (44,034 ) Warranty reserve, end of year $ 108,053 $ 103,700 $ 94,513

Fair Value

Fair Value	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value	Fair Value GAAP assigns a fair value hierarchy to the inputs used to measure fair value. Level 1 inputs are quoted prices in active markets for identical assets and liabilities. Level 2 inputs are inputs other than quoted market prices that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs. Financial Instruments The estimated fair values of our Senior Notes as of December 31, 2019 and 2018 were $626,520 and $594,000 , respectively. The estimated fair value is based on recent market prices of similar transactions, which is classified as Level 2 within the fair value hierarchy. The carrying values at December 31, 2019 and 2018 were $598,301 and $597,681 , respectively. Except as otherwise noted below, we believe that insignificant differences exist between the carrying value and the fair value of our financial instruments, which consists primarily of cash equivalents, due to their short term nature. Derivative Instruments and Mortgage Loans Held for Sale In the normal course of business, NVRM enters into contractual commitments to extend credit to buyers of single-family homes with fixed expiration dates. The commitments become effective when the borrowers “lock-in” a specified interest rate within time frames established by NVRM. All borrowers are evaluated for credit worthiness prior to the extension of the commitment. Market risk arises if interest rates move adversely between the time of the “lock-in” of rates by the borrower and the sale date of the loan to a broker/dealer. To mitigate the effect of the interest rate risk inherent in providing rate lock commitments to borrowers, NVRM enters into optional or mandatory delivery forward sales contracts to sell whole loans and mortgage-backed securities to broker/dealers. The forward sales contracts lock-in an interest rate and price for the sale of loans similar to the specific rate lock commitments. NVRM does not engage in speculative or trading derivative activities. Both the rate lock commitments to borrowers and the forward sale contracts to broker/dealers are undesignated derivatives and, accordingly, are marked to fair value through earnings. At December 31, 2019 , there were contractual commitments to extend credit to borrowers aggregating $581,065 and open forward delivery contracts aggregating $986,041 , which hedge both the rate lock loan commitments and closed loans held for sale. The fair value of our rate lock commitments to borrowers and the related input levels includes, as applicable: i) the assumed gain/loss of the expected resultant loan sale (Level 2); ii) the effects of interest rate movements between the date of the rate lock and the balance sheet date (Level 2); and iii) the value of the servicing rights associated with the loan (Level 2). The assumed gain/loss considers the excess servicing to be received or buydown fees to be paid upon securitization of the loan. The excess servicing and buydown fees are calculated pursuant to contractual terms with investors. To calculate the effects of interest rate movements, NVRM utilizes applicable published mortgage-backed security prices, and multiplies the price movement between the rate lock date and the balance sheet date by the notional loan commitment amount. NVRM sells all of its loans on a servicing released basis, and receives a servicing released premium upon sale. Thus, the value of the servicing rights is included in the fair value measurement and is based upon contractual terms with investors and varies depending on the loan type. NVRM assumes a fallout rate when measuring the fair value of rate lock commitments. Fallout is defined as locked loan commitments for which NVRM does not close a mortgage loan and is based on historical experience. The fair value of NVRM’s forward sales contracts to broker/dealers solely considers the market price movement of the same type of security between the trade date and the balance sheet date (Level 2). The market price changes are multiplied by the notional amount of the forward sales contracts to measure the fair value. Mortgage loans held for sale are recorded at fair value when closed, and thereafter are carried at the lower of cost or fair value, net of deferred origination costs, until sold. Fair value is measured using Level 2 inputs. As of December 31, 2019 , the fair value of loans held for sale of $492,125 included on the accompanying consolidated balance sheet has been increased by $7,019 from the aggregate principal balance of $485,106 . As of December 31, 2018 , the fair value of loans held for sale of $458,324 were increased by $10,880 from the aggregate principal balance of $447,444 . The fair value measurement of NVRM's undesignated derivative instruments was as follows: As of December 31, 2019 2018 Rate lock commitments: Gross assets $ 8,132 $ 13,831 Gross liabilities 497 345 Net rate lock commitments $ 7,635 $ 13,486 Forward sales contracts: Gross assets $ 377 $ 64 Gross liabilities 920 10,121 Net forward sales contracts $ (543 ) $ (10,057 ) As of December 31, 2019 and 2018 , the net rate lock commitments are reported in mortgage banking "Other assets" and the net forward sales contracts are reported in mortgage banking "Accrued expenses and other liabilities" on the accompanying consolidated balance sheets. The fair value measurement as of December 31, 2019 was as follows: Notional or Principal Amount Assumed Gain/(Loss) From Loan Sale Interest Rate Movement Effect Servicing Rights Value Security Price Change Total Fair Value Measurement Gain/(Loss) Rate lock commitments $ 581,065 $ 1,832 $ 405 $ 5,398 $ — $ 7,635 Forward sales contracts $ 986,041 — — — (543 ) (543 ) Mortgages held for sale $ 485,106 1,976 (285 ) 5,328 — 7,019 Total fair value measurement $ 3,808 $ 120 $ 10,726 $ (543 ) $ 14,111 The total fair value measurement as of December 31, 2018 was $14,309 . NVRM recorded a fair value adjustment to expense of $198 for the year ended December 31, 2019 , and fair value adjustments to income of $8,485 and $1,638 for the years ended December 31, 2018 and 2017 , respectively. Unrealized gains/losses from the change in the fair value measurements are included in earnings as a component of mortgage banking fees in the accompanying consolidated statements of income. The fair value measurement will be impacted in the future by the change in the value of the servicing rights, interest rate movements, security price fluctuations, and the volume and product mix of NVRM’s closed loans and locked loan commitments.

Significant Accounting Policies [Line Items]
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include the accounts of NVR, Inc. and its subsidiaries (“NVR”, the “Company”, "we", "us", or "our") and certain other entities in which the Company is deemed to be the primary beneficiary (see Notes 3 and 4 herein for additional information). All significant intercompany transactions have been eliminated in consolidation.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Management continually evaluates the estimates used to prepare the consolidated financial statements and updates those estimates as necessary. In general, our estimates are based on historical experience, on information from third party professionals, and other various assumptions that are believed to be reasonable under the facts and circumstances. Actual results could differ materially from those estimates made by management.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include short-term investments with original maturities of three months or less. Restricted Cash Homebuilding restricted cash was attributable to customer deposits for certain home sales. Mortgage banking restricted cash includes amounts collected from customers for loans in process and closed mortgage loans held for sale. At December 31, 2019 and 2018 , $281 and $320 , respectively, of cash related to a consolidated variable interest entity is included in homebuilding “Other assets” on the accompanying consolidated balance sheet.
Homebuilding Inventory	Homebuilding Inventory The carrying value of inventory is stated at the lower of cost or market value. Cost of lots and completed and uncompleted housing units represent the accumulated actual cost of the units. Field construction supervisors’ salaries and related direct overhead expenses are included in inventory costs. Interest costs are not capitalized into inventory, with the exception of land under development and joint venture investments, as applicable (see below). Upon settlement, the cost of the unit is expensed on a specific identification basis. Cost of building materials is determined on a first-in, first-out basis. Sold inventory is evaluated for impairment based on the contractual sales price compared to the total estimated cost to construct. Unsold inventory is evaluated for impairment by analyzing recent comparable sales prices within the applicable community compared to the costs incurred to date plus the expected costs to complete. Any calculated impairments are recorded immediately.
Contract Land Deposits	Contract Land Deposits We purchase finished lots under fixed price lot purchase agreements (“Lot Purchase Agreements”) that require deposits that may be forfeited if we fail to perform under the contract. The deposits are in the form of cash or letters of credit in varying amounts and represent a percentage of the aggregate purchase price of the finished lots. We maintain an allowance for losses on contract land deposits that reflects our judgment of the present loss exposure in the existing contract land deposit portfolio at the end of the reporting period. To analyze contract land deposit impairments, we conduct a loss contingency analysis each quarter. In addition to considering market and economic conditions, we assess contract land deposit impairments on a community-by-community basis pursuant to the purchase contract terms, analyzing, as applicable, current sales absorption levels, recent sales’ direct profit, the dollar differential between the contractual purchase price and the current market price for lots, a developer’s performance, a developer’s financial ability or willingness to reduce lot prices to current market prices, if necessary, and the contract’s default status by either us or the developer along with an analysis of the expected outcome of any such default. Our analysis is focused on whether we can sell houses at an acceptable margin and sales pace in a particular community in the current market with which we are faced. Because we do not own the finished lots on which we have placed a contract land deposit, if the above analysis leads to a determination that we cannot sell homes at an acceptable margin and sales pace at the current contractual lot price, we then determine whether we will elect to default under the contract, forfeit the deposit and terminate the contract, or whether we will attempt to restructure the Lot Purchase Agreement, which may require us to forfeit the deposit to obtain contract concessions from a developer. We also assess whether impairment is present due to collectibility issues resulting from a developer’s non-performance because of financial or other conditions. For the year ended December 31, 2019 we recognized a net pre-tax recovery of $680 of contract land deposits previously determined to be unrecoverable. For the years ended December 31, 2018 and 2017 , we incurred net pre-tax charges of $5,115 and $1,238 , respectively, related to impairment of contract land deposits. The contract land deposit assets on the accompanying consolidated balance sheets are shown net of the allowance for losses of $27,572 and $29,216 at December 31, 2019 and 2018 , respectively.
Land Under Development	Land Under Development On a limited basis, we directly acquire raw parcels of land already zoned for its intended use to develop into finished lots. Land under development includes the land acquisition costs, direct improvement costs, capitalized interest, where applicable, and real estate taxes. Land under development, including the land under development held by our unconsolidated joint ventures and the related joint venture investments, is reviewed for potential write-downs when impairment indicators are present. In addition to considering market and economic conditions, we assess land under development impairments on a community-by-community basis, analyzing, as applicable, current sales absorption levels, recent sales’ direct profit, and the dollar differential between the projected fully-developed cost of the lots and the current market price for lots. If indicators of impairment are present for a community, we perform an analysis to determine if the undiscounted cash flows estimated to be generated by those assets are less than their carrying amounts, and if so, impairment charges are required to be recorded in an amount by which the carrying amount of the assets exceeds the fair value of such assets. Our determination of fair value is primarily based on discounting the estimated future cash flows at a rate commensurate with the inherent risks associated with the assets and related estimated cash flow streams. See Notes 4 and 5 for further discussion of joint venture investments and land under development, respectively.
Property, Plant, and Equipment	Property, Plant, and Equipment Property, plant, and equipment are carried at cost less accumulated depreciation and amortization. Depreciation is based on the estimated useful lives of the assets using the straight-line method. Model home furniture and fixtures are generally depreciated over a 2 -year period, office facilities and other equipment are depreciated over a period of 3 to 10 years and production facilities are depreciated over periods of 5 to 40 years .
Intangible Assets	Intangible Assets On December 31, 2012, we acquired substantially all of the assets of Heartland Homes, Inc., which resulted in us recording finite-lived intangible assets and goodwill. We completed our annual assessment for impairment of goodwill and management determined that there was no impairment. As of December 31, 2019 and 2018 , finite-lived intangible assets, net of accumulated amortization, totaled $466 and $621 , respectively. The remaining finite-lived intangible assets will be amortized on a straight-line basis over 3 years. As of both December 31, 2019 and 2018 , the goodwill value was $441 . Finite-lived intangible assets and goodwill are included in homebuilding "Other assets" in the accompanying consolidated balance sheets.
Warranty/Product Liability Reserves	Warranty/Product Liability Reserves We establish warranty and product liability reserves ("Warranty Reserve") to provide for estimated future expenses as a result of construction and product defects, product recalls and litigation incidental to our homebuilding business. Liability estimates are determined based on management’s judgment considering such factors as historical experience, the likely current cost of corrective action, manufacturers’ and subcontractors’ participation in sharing the cost of corrective action, consultations with third party experts such as engineers, and discussions with our general counsel and outside counsel retained to handle specific product liability cases.
Mortgage Loans Held for Sale, Derivatives and Hedging Activities	Mortgage Repurchase Reserve, Mortgage Loans Held for Sale and Derivatives and Hedging Activities We originate several different loan products to our customers to finance the purchase of a home through our wholly-owned mortgage subsidiary, NVR Mortgage Finance, Inc. (“NVRM”). NVRM sells all of the loans it originates into the secondary market on a servicing released basis, typically within 30 days from closing. All of the loans that NVRM originates are underwritten to the standards and specifications of the ultimate investor. Those underwriting standards are typically equal to or more stringent than the underwriting standards required by Fannie Mae (“FNMA”), Ginnie Mae (“GNMA”), Freddie Mac ("FHLMC"), the Department of Veterans Affairs (“VA”) and the Federal Housing Administration (“FHA”). Insofar as NVRM underwrites its originated loans to those standards, NVRM bears no increased concentration of credit risk from the issuance of loans, except in certain limited instances where repurchases or early payment default occur. NVRM employs a quality control department to ensure that its underwriting controls are effectively operating, and further assesses the underwriting function as part of its assessment of internal controls over financial reporting. NVRM maintains a reserve for losses on mortgage loans originated that reflects our judgment of the present loss exposure in the loans that NVRM has originated and sold. The reserve is calculated based on an analysis of historical experience and exposure (see Note 16 herein for further information). Mortgage loans held for sale are recorded at fair value when closed, and thereafter are carried at the lower of cost or fair value, net of deferred origination costs, until sold. In the normal course of business, NVRM enters into contractual commitments to extend credit to buyers of single-family homes with fixed expiration dates. The commitments become effective when the borrowers “lock-in” a specified interest rate within time frames established by NVRM. All borrowers are evaluated for credit worthiness prior to the extension of the commitment. Market risk arises if interest rates move adversely between the time of the “lock-in” of rates by the borrower and the sale date of the loan to a broker/dealer. To mitigate the effect of the interest rate risk inherent in providing rate lock commitments to borrowers, NVRM enters into optional or mandatory delivery forward sale contracts to sell whole loans and mortgage-backed securities to broker/dealers. The forward sale contracts lock-in an interest rate and price for the sale of loans similar to the specific rate lock commitments. NVRM does not engage in speculative or trading derivative activities. Both the rate lock commitments to borrowers and the forward sale contracts to broker/dealers are undesignated derivatives, and, accordingly, are marked to fair value through earnings. At December 31, 2019 , there were contractual commitments to extend credit to borrowers aggregating $581,065 , and open forward delivery sale contracts aggregating $986,041 , which hedge both the rate lock loan commitments and closed loans held for sale (see Note 15 herein for a description of the Company’s fair value accounting).
Earnings Per Share	Earnings per Share The following weighted average shares and share equivalents were used to calculate basic and diluted earnings per share for the years ended December 31, 2019 , 2018 and 2017 : Year Ended December 31, 2019 2018 2017 Weighted average number of shares outstanding used to calculate basic EPS 3,641 3,631 3,733 Dilutive securities: Stock options and restricted share units 332 461 507 Weighted average number of shares and share equivalents outstanding used to calculate diluted EPS 3,973 4,092 4,240 The assumed proceeds used in the treasury method for calculating our diluted earnings per share includes the amount the employee must pay upon exercise and the amount of compensation cost attributed to future services not yet recognized. The following stock options issued under equity incentive plans were outstanding during the years ended December 31, 2019 , 2018 and 2017 , but were not included in the computation of diluted earnings per share because the effect would have been anti-dilutive. Year Ended December 31, 2019 2018 2017 Anti-dilutive securities 319 370 15
Revenues-Homebuilding Operations	Revenues – Homebuilding Operations
Mortgage Banking Fees	Mortgage Banking Fees Mortgage banking fees include income earned by NVRM for originating mortgage loans, servicing mortgage loans held on an interim basis, title fees, gains and losses on the sale of mortgage loans and mortgage servicing and other activities incidental to mortgage banking. Mortgage banking fees are generally recognized after the loan has been sold to an unaffiliated, third party investor.
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted 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 on the deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. See Note 11 herein for discussion of the impact on the Company's deferred tax asset resulting from the enactment of the Tax Cuts and Jobs Act in December 2017. ASC 740-10, Income Taxes , provides that a tax benefit from an uncertain tax position may be recognized when it is more-likely-than-not (defined as a likelihood of more than 50%) that the position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits. If a tax position does not meet the more-likely-than-not recognition threshold, despite our belief that its filing position is supportable, the benefit of that tax position is not recognized in the statements of income. We recognize interest related to unrecognized tax benefits as a component of income tax expense. Based on our historical experience in dealing with various taxing authorities, we have found that it is the administrative practice of the taxing authorities to not seek penalties from us for the tax positions we have taken on our returns related to our unrecognized tax benefits. Therefore, we do not accrue penalties for the positions in which we have an unrecognized tax benefit. We recognize unrecognized tax benefits in the period that the uncertainty is eliminated by either affirmative agreement of the uncertain tax position by the applicable taxing authority, by expiration of the applicable statute of limitation, or by determination in accordance with certain states’ administrative practices that the uncertain tax position has been effectively settled (see Note 11 herein for further information).
Financial Instruments	Financial Instruments Except as otherwise noted herein, we believe that the carrying value approximates the fair value of our financial instruments (see Note 15 herein for further information).
Equity-Based Compensation	Equity-Based Compensation We recognize equity-based compensation expense within its income statement for all share-based payment arrangements, which includes non-qualified stock options to purchase shares of NVR common stock ("Options") and restricted share units ("RSUs"). Compensation expense is based on the grant-date fair value of the Options and RSUs granted, and is recognized on a straight-line basis over the requisite service period for the entire award (from the date of grant through the period of the last separately vesting portion of the grant). Options and RSUs which are subject to a performance condition are treated as a separate award from the “service-only” Options and RSUs, and compensation expense is recognized when it becomes probable that the stated performance target will be achieved. We calculate the fair value of our Options, which are non-publicly traded, using the Black-Scholes option-pricing model. The grant date fair value of the RSUs is the closing price of our common stock on the day immediately preceding the date of grant. The reversal of compensation expense previously recognized for grants forfeited is recorded in the period in which the forfeiture occurs. Our equity-based compensation plans are accounted for as equity-classified awards (see Note 12 herein for further discussion of equity-based compensation plans).
Comprehensive Income	Comprehensive Income For the years ended December 31, 2019 , 2018 and 2017 , comprehensive income equaled net income; therefore, a separate statement of comprehensive income is not included in the accompanying consolidated financial statements.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements Leases On January 1, 2019, we adopted ASU 2016-02, Leases (Topic 842) , which requires the recognition of our leases on the balance sheet as right-of-use ("ROU") assets and lease liabilities. We elected to adopt Topic 842 using the effective date transition method, which permits us to apply the new standard prospectively and present comparative years under legacy GAAP. In adoption of the standard, we also elected the following: • to apply the package of practical expedients during transition, under which we were not required to reassess as of the date of adoption (i) whether any of our contracts are or contain leases, (ii) the classifications of our leases, and (iii) any initial direct costs related to those leases. • to exclude leases with an initial lease term of 12 months or less from the recognition requirements under Topic 842. • to utilize the portfolio approach for certain office equipment leases, grouping leases by asset type which have similar lease terms and payment schedules. Upon adoption, on January 1, 2019 we recorded a lease liability of $85,516 and a ROU asset of $79,345 , which was recorded net of previously recognized straight-line operating lease adjustments on existing leases. The adoption of Topic 842 did not have an impact on our recognition of lease expense. See additional lease disclosures in Note 13. Recently Issued Accounting Pronouncements In June 2016, FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326) , which significantly changes the way impairment of financial assets is recognized. The standard will require immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets, which will generally result in earlier recognition of allowances for credit losses on loans and other financial instruments. The standard’s provisions will be applied as a cumulative-effect adjustment to beginning retained earnings as of the effective date. The standard is effective for us as of January 1, 2020. We do not believe that the adoption of this standard will have a material effect on our consolidated financial statements and related disclosures. In January 2017, FASB issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 350), Simplifying the Test for Goodwill Impairment . The standard’s objective is to simplify the subsequent measurement of goodwill by eliminating the second step from the goodwill impairment test. Under the amendments in the standard, an entity would perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. If the carrying amount of a reporting unit exceeds its fair value, an impairment charge would then be recognized, not to exceed the amount of goodwill allocated to that reporting unit. The standard is effective for us on January 1, 2020. We do not believe that the adoption of this standard will have a material effect on our consolidated financial statements and related disclosures.

Black-Scholes Option-Pricing Model Assumptions	To estimate the grant-date fair value of our Options, we use the Black-Scholes option-pricing model (the “Pricing Model”). The Pricing Model estimates the per share fair value of an option on its date of grant based on the following factors: the option’s exercise price; the price of the underlying stock on the date of grant; the estimated dividend yield; a risk-free interest rate; the estimated option term; and the expected volatility. For the risk-free interest rate, we use U.S. Treasury STRIPS which mature at approximately the same time as the option’s expected holding term. For expected volatility, we have concluded that our historical volatility over the option’s expected holding term provides the most reasonable basis for this estimate. The fair value of the Options granted during 2019 , 2018 and 2017 was estimated on the grant date using the Pricing Model, based on the following assumptions: 2019 2018 2017 Estimated option life (years) 5.55 5.06 5.26 Risk free interest rate (range) 1.51%-2.73% 2.19%-3.13% 1.53%-2.38% Expected volatility (range) 19.17%-22.01% 16.57%-20.05% 15.09%-17.95% Expected dividend rate — % — % — % Weighted average grant-date fair value per share of options granted $ 661.01 $ 687.81 $ 494.17 The grant date fair value per share of $2,517.06 for the RSUs was the closing price of our common stock on the day immediately preceding the date of grant.
Exercised Option Proceeds	Compensation cost for Options and RSUs is recognized on a straight-line basis over the requisite service period for the entire award (from the date of grant through the period of the last separately vesting portion of the grant). For the recognition of equity-based compensation, the Options and RSUs which are subject to a performance condition are treated as a separate award from the “service-only” Options and RSUs, and compensation expense is recognized when it becomes probable that the stated performance target will be achieved. We currently believe that it is probable that the stated performance condition will be satisfied at the target level and are recognizing compensation expense related to such Options and RSUs accordingly. Compensation cost is recognized within the income statement in the same expense line as the cash compensation paid to the respective employees. We recognize forfeitures of equity-based awards as a reduction to compensation costs in the period in which they occur. In 2019 , 2018 and 2017 , we recognized $78,532 , $75,701 , and $44,562 in equity-based compensation costs, respectively, and approximately $16,800 , $17,200 , and $17,100 in tax benefit related to equity-based compensation costs, respectively. As of December 31, 2019 , the total unrecognized compensation cost for all outstanding Options and RSUs equaled approximately $209,000 . The unrecognized compensation cost will be recognized over each grant’s applicable vesting period with the latest vesting date being December 31, 2025. The weighted-average period over which the unrecognized compensation will be recorded is equal to approximately 2.4 years. We settle Option exercises and vesting of RSUs by issuing shares of treasury stock. Shares are relieved from the treasury account based on the weighted average cost of treasury shares acquired. During the years ended December 31, 2019 , 2018 and 2017 , we issued 276 , 188 and 165 shares, respectively, from the treasury account for Option exercises and vesting of RSUs. Information with respect to the vested RSUs and exercised Options is as follows: Year Ended December 31, 2019 2018 2017 Aggregate exercise proceeds $ 274,028 $ 174,110 $ 140,525 Aggregate intrinsic value on exercise dates $ 593,162 $ 355,318 $ 206,890
