Accounting Policies [Abstract]
Description of Business and Summary of Significant Accounting Policies	1	Description of Business and Summary of Significant Accounting Policies
	Description of Business—New Relic, Inc. (the “Company” or “New Relic”) was incorporated in Delaware on February 20, 2008. The Company is a software-as-a-service provider of software analytics products which allow users to monitor software performance with .NET, Java, JavaScript, Node.js, PHP, Python, and Ruby applications deployed in a cloud or in a data center. New Relic’s software analytics products enable developers and operation teams to monitor, troubleshoot, and optimize their applications.
	Basis of Presentation—These unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles, or GAAP, and applicable rules and regulations of the Securities and Exchange Commission, or SEC, regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in our final prospectus filed with the SEC on December 12, 2014 pursuant to Rule 424(b) of the Securities Act of 1933, as amended, relating to our Registration Statement on Form S-1 (File No. 333-200078). There have been no changes to our significant accounting policies described in the prospectus that have had a material impact on our condensed consolidated financial statements and related notes.
	The unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, our comprehensive loss and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year ending March 31, 2015. The condensed consolidated balance sheet as of March 31, 2014 included herein was derived from the audited financial statements as of that date.
	Initial Public Offering—In December 2014, we completed our initial public offering, or IPO, in which we issued and sold 5,750,000 million shares of common stock at a public offering price of $23.00 per share. We received aggregate proceeds of approximately $123.0 million from the sale of shares of common stock, net of underwriters’ discounts and commissions, but before deducting paid and unpaid offering expenses of approximately $3.1 million.
	The sale of common stock in the IPO triggered the weighted average anti-dilution provisions set forth in the Company’s amended and restated certificate of incorporation. At the IPO price of $23.00 per share, the per share conversion rate for the Company’s Series F convertible preferred stock into common stock was approximately 1:1.02. The conversion rate for the Company’s Series A, Series B, Series C, Series D, and Series E convertible preferred stock was 1:1. As a result of the IPO, the 24,813,343 shares of the Company’s convertible preferred stock outstanding automatically converted into 24,885,778 shares of the Company’s common stock.
	Use of Estimates—The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of income and expenses during the reporting period. These estimates are based on information available as of the date of the condensed consolidated financial statements; therefore, actual results could differ from management’s estimates.
	Concentration of Risk—At December 31, 2014, and March 31, 2014, there was no customer that represented more than 10% of our accounts receivable balance. There were no customers that individually exceeded 10% of our revenue during the three and nine months ended December 31, 2014.
	Short-term Investments—Short-term investments consist of money market funds, commercial paper, U.S. treasury securities, U.S. agency securities, corporate debt securities, and asset-back securities and are classified as available-for-sale securities. The Company has classified its investments as current based on the nature of the investments and their availability for use in current operations. Available-for-sale securities are carried at fair value with unrealized gains and losses reported as a component of accumulated other comprehensive loss, while realized gains and losses and other-than-temporary impairments are reported within the statement of operations. For the periods presented, realized and unrealized gains and losses on investments were not material. An impairment charge is recorded in the consolidated statements of operations for declines in fair value below the cost of an individual investment that are deemed to be other than temporary. The Company assesses whether a decline in value is temporary based on the length of time that the fair market value has been below cost, the severity of the decline and the intent and ability to hold or sell the investment. The Company did not identify any marketable securities as other-than-temporarily impaired as of December 31, 2014. The Company did not have marketable securities as of March 31, 2014.
	Business Combinations—The Company recognizes identifiable assets acquired and liabilities assumed at their acquisition date fair value. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While we use our best estimates and assumptions as a part of the purchase price allocation process to accurately value assets acquired and liabilities assumed at the acquisition date, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill to the extent that we identify adjustments to the preliminary purchase price allocation. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our consolidated statements of operations.
	Goodwill—Goodwill represents the excess of the purchase price of an acquired business over the fair value of the underlying net tangible and intangible assets. Goodwill is evaluated for impairment annually in the third quarter of the Company’s fiscal year, and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. Triggering events that may indicate impairment include, but are not limited to, a significant adverse change in customer demand or business climate that could affect the value of goodwill or a significant decrease in expected cash flows. Since inception through December 31, 2014, the Company did not have any goodwill impairment.
	Intangible Assets—Intangible assets consist of identifiable intangible assets, primarily developed technology, resulting from the Company’s acquisitions. Acquired intangible assets are recorded at cost, net of accumulated amortization. Intangible assets are amortized on a straight-line basis over their estimated useful lives.
	Recent Accounting Pronouncements—In May 2014, the Financial Accounting Standards Board (“FASB”) issued new guidance related to the recognition and reporting of revenue that establishes a comprehensive new revenue recognition model designed to depict the transfer of goods or services to a customer in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. The guidance allows for the use of either the full or modified retrospective transition method, and the standard will be effective for the Company in our fiscal year beginning April 1, 2017; early adoption is not permitted. The Company is currently evaluating the impact of this new standard on its condensed consolidated financial statements, as well as which transition method the Company intends to use.

Business Combinations [Abstract]
Business Combination	2	Business Combination
	On October 6, 2014, the Company completed the acquisition of Few Ducks, S.L., (“Ducksboard”), a provider of real-time dashboards for tracking business metrics from a broad set of application sources, pursuant to which the Company acquired all of the capital stock of Ducksboard for 121,493 shares of the Company’s common stock, of which 108,234 shares have been issued and up to 13,259 shares will be released on the twelve month anniversary of the closing date, and $2.3 million in cash resulting in an aggregate preliminary purchase price of $4.2 million. Of the total purchase price, $2.1 million was allocated to goodwill, $2.8 million to identifiable intangible assets, and $0.7 million to net liabilities assumed. The addition of the Ducksboard technology complements the Company’s visualization expertise and will readily expand the sources of data that are available to customers via the Company’s Software Analytics data cloud. The Company accounted for the acquisition of Ducksboard as a purchase of a business. Goodwill generated from the acquisition is attributable to expected synergies from future growth and potential future monetization opportunities, and is not deductible for tax purposes. Pro forma revenue and results of operations have not been presented because the historical results of Ducksboard were not material to our condensed consolidated financial statements in any period presented.
	In connection with the acquisition, the Company may also issue 128,507 shares of its common stock to certain employees of Ducksboard, contingent upon their continuous employment with the Company. As such, compensation expense will be recorded ratably over the respective service period.

	Included in restricted cash									$	5,601
	Included in other liabilities, non-current									$	830
	Level 3 instruments consist solely of the Company’s preferred stock warrant liability. Prior to the Company’s IPO, outstanding warrants to purchase shares of the Company’s Series A and Series D convertible preferred stock were classified as other liabilities. The initial liability recorded was adjusted for changes in the fair values of the Company’s preferred stock warrants during each reporting period and was recorded as a component of other (expense) income, net in the statement of operations.
	Upon the closing of the Company’s IPO and the conversion of the underlying preferred stock to common stock, the Company’s warrants to purchase shares of Series A convertible preferred stock were converted into warrants to purchase shares of the Company’s common stock. The aggregate fair value of these warrants upon the closing of the IPO was $0.6 million which was reclassified from liabilities to additional paid-in capital, a component of stockholders’ equity (deficit), and the Company ceased recording any further related periodic fair value adjustments. The warrant to purchase shares of the Company’s Series D convertible preferred stock was automatically net exercised for an aggregate of 12,193 shares of common stock upon closing of the Company’s IPO in December 2014. The Company estimated the fair values of these warrants using the Black-Scholes option-pricing model, based on the inputs for the estimated fair value of the underlying convertible preferred stock at the valuation measurement date, the remaining contractual term of the warrant, risk-free interest rates, expected dividend rates and expected volatility of the price of the underlying convertible preferred stock. These estimates were based on subjective assumptions.
	The following table sets forth a summary of the changes in the fair value of the Company’s Level 3 financial instruments as follows (in thousands):
			Preferred Stock
			Warrant
			Liability
	Balance at March 31, 2014		$	830
	Change in fair value of preferred stock warrant liability			82
	Reclassification of preferred stock warrant liabilities to additional paid-in capital in conjunction with the conversion of the convertible preferred stock into common stock upon the closing of the Company’s IPO			(912	)
	Balance at December 31, 2014		$	—
	Gross unrealized gains or losses for cash equivalents and available-for-sale marketable securities as of December 31, 2014 and March 31, 2014 were not material. As of December 31, 2014 and March 31, 2014, there were no securities that were in an unrealized loss position for more than 12 months.
	The following table classifies our available-for-sale short-term investments by contractual maturities as of December 31, 2014 and March 31, 2014 (in thousands):
			December 31,			March 31,
			2014			2014
	Due in one year		$	17,487		$	—
	Due in one to three years			19,558			—
	Total		$	37,045		$	—
	For certain other financial instruments, including accounts receivable, accounts payable and other current liabilities, the carrying amounts approximate their fair value due to the relatively short maturity of these balances. Based on borrowing rates available to us for loans with similar terms and maturities, the carrying value of borrowings approximates fair value or Level 2 within the fair value hierarchy.
	There were no transfers between fair value measurement levels during the three and nine months ended December 31, 2014.

	Leases —The Company leases office space under non-cancelable operating lease agreements, which expire from 2015 through 2023.
	Deferred Rent—Certain of the Company’s operating leases contain rent holidays, allowances, and rent escalation provisions. For these leases, the Company recognizes the related rental expense on a straight-line basis over the life of the lease from the date the Company takes possession of the office and records the difference between amounts charged to operations and amounts paid as deferred rent. These rent holidays, allowances, and rent escalations are considered in determining the straight-line expense to be recorded over the lease term. As of December 31, 2014 and March 31, 2014, $4.7 million and $3.9 million, respectively, was recorded as deferred rent.
	Rent expense, net of sublease income, for operating leases was $1.3 million and $1.3 million for the three months ended December 31, 2014 and 2013, respectively, and $3.9 million and $3.4 million for the nine months ended December 31, 2014 and 2013, respectively.

	Legal Proceedings—From time to time, the Company may become involved in various legal proceedings in the ordinary course of its business, and may be subject to third-party infringement claims.
	On November 5, 2012, CA, Inc. filed suit against the Company in the United States District Court, Eastern District of New York for alleged patent infringement. CA, Inc.’s complaint against the Company claims that certain aspects of the Company’s products infringe certain patents held by CA, Inc. The Company cannot at this time predict the likely outcome of this proceeding or estimate the amount or range of loss or possible loss that may arise from it. The Company has not accrued any loss related to the outcome of this case as of December 31, 2014.
	In the normal course of business, the Company may agree to indemnify third parties with whom it enters into contractual relationships, including customers, lessors, and parties to other transactions with the Company, with respect to certain matters. The Company has agreed, under certain conditions, to hold these third parties harmless against specified losses, such as those arising from a breach of representations or covenants, other third-party claims that the Company’s products when used for their intended purposes infringe the intellectual property rights of such other third parties, or other claims made against certain parties. To date, the Company has not incurred any costs as a result of such obligations and has not accrued any liabilities related to such obligations in the condensed consolidated financial statements. In addition, the Company indemnifies its officers, directors, and certain key employees while they are serving in good faith in their respective capacities. The Company does not currently believe there is a reasonable possibility that a loss may have been incurred under these indemnification obligations. To date, there have been no claims under any such indemnification provisions.

	Convertible preferred stock — Upon the completion of the IPO, all outstanding convertible preferred stock was converted into 24,885,778 shares of common stock and the Company’s certificate of incorporation was amended and restated to authorize the Company to issue 10,000,000 shares of preferred stock with a par value of $0.001 per share.
	Common stock authorized — Upon the completion of the IPO, the Company’s certificate of incorporation was amended and restated to increase the amount of common stock authorized for issuance from 55,000,000 to 100,000,000 common shares with a par value of $0.001 per share.
	Employee Stock Purchase Plan — The Company’s board of directors adopted, and the Company’s stockholders approved, the Company’s 2014 Employee Stock Purchase Plan, or ESPP, which became effective in December 2014. The ESPP initially reserved and authorized the issuance of up to 1,000,000 shares of common stock. The ESPP provides that the number of shares reserved and available for issuance under the ESPP will automatically increase each April, beginning on April 1, 2015, by the lesser of 500,000 shares, 1% of the number of the Company’s common stock shares issued and outstanding on the immediately preceding March 31, or such lesser number of shares as determined the Company’s board of directors.
	2008 Equity Incentive Plan — The Company’s board of directors adopted the 2008 Equity Incentive Plan, or the 2008 Plan, in February 2008. The 2008 Equity Incentive Plan was terminated in connection with our IPO, and accordingly, no shares are available for future issuance under this plan. The 2008 Equity Incentive Plan continues to govern outstanding awards granted thereunder.
	2014 Equity Incentive Plan — The Company’s board of directors adopted, and the Company’s stockholders approved, the Company’s 2014 Equity Incentive Plan, or the 2014 Plan, which became effective in December 2014. The 2014 Plan serves as the successor to our 2008 Plan. The 2014 Plan initially reserved and authorized the issuance of 5,000,000 shares of our common stock. Additionally, shares not issued or subject to outstanding grants under the 2008 Plan became available under the 2014 Plan, resulting in a total of 5,184,878 available shares under the 2014 Plan as of the effective date of the 2014 Plan. Pursuant to the terms of the 2014 Plan, any shares subject to outstanding stock options or other stock awards under the 2008 Plan that (i) expire or terminate for any reason prior to exercise or settlement, (ii) are forfeited because of the failure to meet a contingency or condition required to vest such shares or otherwise return to the Company or (iii) are reacquired, withheld (or not issued) to satisfy a tax withholding obligation in connection with an award or to satisfy the purchase price or exercise price of a stock award) will become available for issuance pursuant to awards granted under the 2014 Plan. The 2014 Plan provides that the number of shares reserved and available for issuance under the plan will automatically increase each April 1, beginning on April 1, 2015, by 5% of the outstanding number of shares of the Company’s common stock shares issued and outstanding on the immediately preceding March 31, or such lesser number of shares as determined by the Company board of directors. As of December 31, 2014, there were 5,207,555 shares available for issuance under the 2014 Plan.

Income Tax Disclosure [Abstract]
Income Taxes	8	Income Taxes
	The company recorded an income tax benefit of $0.1 million for the three and nine months ended December 31, 2014, respectively. This benefit is largely attributable to the deferred benefit associated with the amortization of Spanish intangibles assets, partially offset with state minimum taxes and foreign income taxes associated with our non-US operations. The Company continues to maintain a valuation allowance for its U.S. federal and state deferred tax assets.
	The utilization of the net operating loss (“NOL”) carryforwards is subject to annual limitations under Section 382 of the Internal Revenue Code. Section 382 imposes limitations on a corporation’s ability to utilize its NOL carryforwards if it experiences an “ownership change.” In general terms, an ownership change results from transactions increasing the ownership of certain stockholders in the stock of a corporation by more than 50% over a three-year period. Once an ownership change is deemed to have occurred under Section 382, a limitation on the annual utilization of NOL carryforwards is imposed and, therefore, a portion of the tax loss carryforwards would be subject to the limitation under Section 382.
	The Company files annual income tax returns in multiple taxing jurisdictions around the world. A number of years may elapse before an uncertain tax position is audited and finally resolved. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, the Company believes that its reserves for income taxes reflect the most likely outcome. The Company adjusts these reserves, as well as the related interest, in light of changing facts and circumstances. However, if an ultimate tax assessment exceeds our estimate of tax liabilities, additional tax expense will be recorded.
	At December 31, 2014, the Company had $1.0 million of unrecognized tax benefits, of which none, if recognized, would affect the effective tax rate as most of the unrecognized tax benefit are deferred tax assets currently offset by a valuation allowance. There were no material changes to the unrecognized tax benefits in the three and nine months ended December 31, 2014, and 2013. The Company has elected to recognize interest and penalties related to uncertain tax positions as part of the income tax provision, however, as of December 31, 2014, no such interest and penalties had been recorded.
	Changes to the Company’s uncertain tax positions in the next 12 months that are reasonably possible are not expected to have a significant impact on the Company’s financial position or results of operations.

Earnings Per Share [Abstract]
Net Loss Per Share	9	Net Loss Per Share
	Basic loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the period, less shares subject to repurchase, and excludes any dilutive effects of employee share-based awards and warrants. Diluted net loss per common share is computed giving effect to all potential dilutive common shares, including common stock issuable upon exercise of stock options, and unvested restricted common stock. As the Company had net losses for the three and nine months ended December 31, 2014 and 2013, all potential common shares were determined to be anti-dilutive.
	The following table sets forth the computation of net loss per share attributable to common stockholders, basic and diluted (in thousands, except per share amounts):

Description_of_Business_and_Su1

Description of Business and Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Dec. 31, 2014
Accounting Policies [Abstract]
Description of Business	Description of Business—New Relic, Inc. (the “Company” or “New Relic”) was incorporated in Delaware on February 20, 2008. The Company is a software-as-a-service provider of software analytics products which allow users to monitor software performance with .NET, Java, JavaScript, Node.js, PHP, Python, and Ruby applications deployed in a cloud or in a data center. New Relic’s software analytics products enable developers and operation teams to monitor, troubleshoot, and optimize their applications.
Basis of Presentation	Basis of Presentation—These unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles, or GAAP, and applicable rules and regulations of the Securities and Exchange Commission, or SEC, regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Therefore, these condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes included in our final prospectus filed with the SEC on December 12, 2014 pursuant to Rule 424(b) of the Securities Act of 1933, as amended, relating to our Registration Statement on Form S-1 (File No. 333-200078). There have been no changes to our significant accounting policies described in the prospectus that have had a material impact on our condensed consolidated financial statements and related notes.
	The unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, our comprehensive loss and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year ending March 31, 2015. The condensed consolidated balance sheet as of March 31, 2014 included herein was derived from the audited financial statements as of that date.
Initial Public Offering	Initial Public Offering—In December 2014, we completed our initial public offering, or IPO, in which we issued and sold 5,750,000 million shares of common stock at a public offering price of $23.00 per share. We received aggregate proceeds of approximately $123.0 million from the sale of shares of common stock, net of underwriters’ discounts and commissions, but before deducting paid and unpaid offering expenses of approximately $3.1 million.
	The sale of common stock in the IPO triggered the weighted average anti-dilution provisions set forth in the Company’s amended and restated certificate of incorporation. At the IPO price of $23.00 per share, the per share conversion rate for the Company’s Series F convertible preferred stock into common stock was approximately 1:1.02. The conversion rate for the Company’s Series A, Series B, Series C, Series D, and Series E convertible preferred stock was 1:1. As a result of the IPO, the 24,813,343 shares of the Company’s convertible preferred stock outstanding automatically converted into 24,885,778 shares of the Company’s common stock.
Use of Estimates	Use of Estimates—The preparation of the Company’s condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of income and expenses during the reporting period. These estimates are based on information available as of the date of the condensed consolidated financial statements; therefore, actual results could differ from management’s estimates.
Concentration of Risk	Concentration of Risk—At December 31, 2014, and March 31, 2014, there was no customer that represented more than 10% of our accounts receivable balance. There were no customers that individually exceeded 10% of our revenue during the three and nine months ended December 31, 2014.
Short-term Investments	Short-term Investments—Short-term investments consist of money market funds, commercial paper, U.S. treasury securities, U.S. agency securities, corporate debt securities, and asset-back securities and are classified as available-for-sale securities. The Company has classified its investments as current based on the nature of the investments and their availability for use in current operations. Available-for-sale securities are carried at fair value with unrealized gains and losses reported as a component of accumulated other comprehensive loss, while realized gains and losses and other-than-temporary impairments are reported within the statement of operations. For the periods presented, realized and unrealized gains and losses on investments were not material. An impairment charge is recorded in the consolidated statements of operations for declines in fair value below the cost of an individual investment that are deemed to be other than temporary. The Company assesses whether a decline in value is temporary based on the length of time that the fair market value has been below cost, the severity of the decline and the intent and ability to hold or sell the investment. The Company did not identify any marketable securities as other-than-temporarily impaired as of December 31, 2014. The Company did not have marketable securities as of March 31, 2014.
Business Combinations	Business Combinations—The Company recognizes identifiable assets acquired and liabilities assumed at their acquisition date fair value. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair values of the assets acquired and the liabilities assumed. While we use our best estimates and assumptions as a part of the purchase price allocation process to accurately value assets acquired and liabilities assumed at the acquisition date, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill to the extent that we identify adjustments to the preliminary purchase price allocation. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to our consolidated statements of operations.
Goodwill	Goodwill—Goodwill represents the excess of the purchase price of an acquired business over the fair value of the underlying net tangible and intangible assets. Goodwill is evaluated for impairment annually in the third quarter of the Company’s fiscal year, and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. Triggering events that may indicate impairment include, but are not limited to, a significant adverse change in customer demand or business climate that could affect the value of goodwill or a significant decrease in expected cash flows. Since inception through December 31, 2014, the Company did not have any goodwill impairment.
Intangible Assets	Intangible Assets—Intangible assets consist of identifiable intangible assets, primarily developed technology, resulting from the Company’s acquisitions. Acquired intangible assets are recorded at cost, net of accumulated amortization. Intangible assets are amortized on a straight-line basis over their estimated useful lives.
Recent Accounting Pronouncements	Recent Accounting Pronouncements—In May 2014, the Financial Accounting Standards Board (“FASB”) issued new guidance related to the recognition and reporting of revenue that establishes a comprehensive new revenue recognition model designed to depict the transfer of goods or services to a customer in an amount that reflects the consideration the entity expects to receive in exchange for those goods or services. The guidance allows for the use of either the full or modified retrospective transition method, and the standard will be effective for the Company in our fiscal year beginning April 1, 2017; early adoption is not permitted. The Company is currently evaluating the impact of this new standard on its condensed consolidated financial statements, as well as which transition method the Company intends to use.
