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, when it converted from a Delaware limited liability company called New Relic Software, LLC, which was formed in Delaware in September 2007. The Company is a provider of an integrated, multi-tenant, cloud-based instrumentation and analytics platform that enables users to collect, store and analyze massive amounts of data in real time.
Basis of Presentation	Basis of Presentation —These unaudited condensed consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“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 the Company’s Annual Report on Form 10-K for the fiscal year ended March 31, 2019, as filed with the SEC on May 15, 2019 (the “Annual Report”). In the opinion of management, the unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive loss and cash flows for the interim period, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year ending March 31, 2020. The condensed consolidated balance sheet as of March 31, 2019 included herein was derived from the audited financial statements as of that date.
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. Significant items subject to such estimates and assumptions include the fair value of share-based awards, fair value of purchased intangible assets and goodwill, fair value of debt and equity components related to the 0.5% convertible senior notes due 2023 (the “Notes”), whether an arrangement is or contains a lease, the discount rate used for operating leases, useful lives of purchased intangible assets, unrecognized tax benefits, expected benefit period for deferred commissions and the capitalization and estimated useful life of the Company’s software development costs. 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—There was no customer that represented more than 10% of the Company’s accounts receivable balance as of June 30, 2019 and March 31, 2019. There were no customers that individually exceeded 10% of the Company’s revenue during the three months ended June 30, 2019 or 2018.
Recent Accounting Pronouncements	Recently Issued Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which amends guidance on reporting credit losses for assets held at amortized cost basis and available-for-sale debt securities. The updated guidance requires that credit losses on available-for-sale debt securities be presented as an allowance rather than as a write-down. The measurement of credit losses for newly recognized financial assets and subsequent changes in the allowance for credit losses are recorded in the statement of income. The update to the standard will be effective for the Company in the fiscal year beginning April 1, 2020; early adoption is permitted in the fiscal year beginning April 1, 2019. The Company has not yet adopted ASU 2016-13 and is currently evaluating the effect the standard will have on its condensed consolidated financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which eliminates Step 2 from the goodwill impairment test. This standard is effective for goodwill impairment tests performed by the Company in the fiscal year beginning April 1, 2020; early adoption is permitted. The Company has not yet adopted ASU 2017-04 and does not believe that this standard will have a material impact on its condensed consolidated financial statements or disclosures. In August 2018, the FASB issued ASU 2018-13, Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which amends ASC 820, Fair Value Measurement. ASU 2018-13 modifies the disclosure requirements for fair value measurements by removing, modifying, or adding certain disclosures. The effective date is the first quarter of fiscal year 2021, with early adoption permitted for the removed disclosures and delayed adoption permitted until fiscal year 2021 for the new disclosures. The removed and modified disclosures will be adopted on a retrospective basis and the new disclosures will be adopted on a prospective basis. The Company has not yet adopted ASU 2018-13 and is currently evaluating the effect the standard will have on its condensed consolidated financial statements. Recently Adopted Accounting Pronouncements In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) which supersedes current guidance related to accounting for leases. This new guidance requires lessees to recognize most leases on their balance sheets as lease right-of-use assets with corresponding lease liabilities and eliminates certain real estate-specific provisions. In July 2018, the FASB also issued ASU No. 2018-11, Leases (Topic 842). The ASU provides an optional transition method that entities can use when adopting the standard and a practical expedient that permits lessors to not separate nonlease components from the associated lease component if certain conditions are met. The new guidance is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period. The Company adopted ASC 842 on April 1, 2019 using a modified retrospective method, under which financial results reported in periods prior to April 1, 2019 were not adjusted. The Company elected the package of transition practical expedients, which among other things, does not require reassessment of historical lease classifications of leases in place as of April 1, 2019. The effect of adopting ASC 842 resulted in the recognition of lease right-of-use assets and corresponding lease liabilities on its condensed consolidated balance sheet. As of June 30, 2019, the aggregate balance of lease right-of-use assets and lease liabilities was $64.2 million and $71.6 million, respectively. The standard did not affect the Company’s condensed consolidated statement of operations or cash flows. In June 2018, the FASB issued ASU 2018-07, regarding Compensation—Stock Compensation (Topic 718), which largely aligns the accounting for share-based compensation for non-employees with employees. The guidance is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period. The Company adopted this standard on April 1, 2019. The adoption did not have a significant impact on its condensed consolidated financial statements. In August 2018, the FASB issued ASU 2018-15, regarding Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40), which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The guidance is effective for annual reporting periods beginning after December 15, 2019, including interim periods within that reporting period. The Company adopted the standard on April 1, 2019. The adoption did not have a significant impact on its condensed consolidated financial statements.
