Accounting Policies [Abstract]
BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation —In our opinion, all adjustments necessary for a fair presentation of the condensed consolidated financial statements have been included. All such adjustments are of a normal and recurring nature. These condensed consolidated financial statements are unaudited and, accordingly, should be read in conjunction with the consolidated financial statements and related notes included in the Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC on March 4, 2021, or the 2020 10-K. Basis of Consolidation —The unaudited condensed consolidated financial statements include the accounts of Root, Inc. and its subsidiaries, all of which are wholly owned. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States, or GAAP. All intercompany accounts and transactions have been eliminated. Use of Estimates —The preparation of the unaudited condensed consolidated financial statements requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates reflected in our unaudited condensed consolidated financial statements include, but are not limited to, reserves for loss and loss adjustment expense, premium write-offs and valuation allowances for income taxes. COVID-19 —In March 2020, the World Health Organization declared COVID-19 to be a global pandemic. The pandemic and related measures taken to contain the spread of COVID-19, such as government-mandated business closures, orders to “shelter in place” and travel and transportation restrictions, have negatively affected the U.S. and global economies, disrupted global supply chains, and led to unprecedented levels of unemployment. We, and other businesses within the insurance industry, have been impacted by certain individual state bulletins that were issued in 2020 and outlined COVID-19 premium relief efforts, including restrictions on the ability to cancel policies for non-payment, requirements to defer insurance payments for up to 60 days and restrictions on increasing policy premiums. The COVID-19 pandemic has impacted and may further impact the broader economic environment, including negatively impacting unemployment levels, economic growth, the proper functioning of financial and capital markets and interest rates. As the COVID-19 pandemic continues, there is uncertainty around the severity and duration of the pandemic and the pandemic’s potential impact on our business and our financial performance. Accordingly, we cannot predict the impact that it may have on our future results of operations and financial condition. Recently Adopted Financial Accounting Standards —In February 2016, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, No. 2016-02, Leases (Topic 842) . The main provision of ASU 2016-02 requires the recognition of right-of-use lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. The guidance also requires disclosures that meet the objective of enabling financial statement users to assess the amount, timing, and uncertainty of related cash flows. We adopted ASU 2016-02 on January 1, 2021. We elected various practical expedients which include: not applying the amended lease accounting guidance to comparative periods; including the carry forward of our leases without reassessing whether any contracts are leases or contain leases, lease classification and initial direct costs; and excluding leases with a term of 12 months or less from lease liability and right-of-use asset recognition. We did not elect the hindsight practical expedient. Our lease agreements contain lease components and non-lease components, both of which we have elected to account for as a single lease component for our real estate asset class. Operating lease expense for operating lease right-of-use assets is recognized on a straight-line basis over the lease term, which may include options to extend or terminate the lease when it is reasonably certain to do so and there is a significant economic incentive to exercise that option. Upon adoption of ASU 2016-02, we recognized an operating lease liability of $16.2 million and corresponding right-of-use asset of $9.9 million, which includes the effect of $6.3 million from reclassifying previously recognized deferred rent and lease exit liabilities as an offset, in accordance with the transition guidance. These lease assets and liabilities are recorded as other assets and other liabilities on the condensed consolidated balance sheets. This transition adjustment was reflected as a non-cash transaction in our condensed consolidated statements of cash flows. The transition did not have a material impact on our results of operations, liquidity or debt covenant compliance under our current debt agreements. For additional information refer to Note 6, “Leases.” Upcoming Accounting Pronouncements— We currently qualify as an "emerging growth company," or EGC, under the Jumpstart Our Business Startups Act of 2012, or JOBS Act, whereby we have the option to adopt new or revised accounting guidance within the same time periods as private companies. We have elected this option, but may ultimately determine it is preferable to take advantage of early adoption provisions offered within the applicable guidance. As of June 30, 2021, the market value of our common stock held by non-affiliates exceeded $700 million. We will follow the adoption criteria for public companies and reflect such adoption criteria in our Annual Report on Form 10-K for the 2021 fiscal year. In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments

LEASES

LEASES	6 Months Ended
	Jun. 30, 2021
Leases [Abstract]
LEASES	LEASESWe primarily have operating leases for offices that support our corporate, claims and customer service functions. We determine if an arrangement is a lease at inception by evaluating whether the arrangement conveys the right to use an identified asset and whether we obtain substantially all of the economic benefits from and have the ability to direct the use of the asset. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. Operating lease right-of-use assets and corresponding operating lease liabilities are recognized upon the commencement date based primarily on the present value of lease payments over the lease term. We use the implicit rate of the lease, if it is readily determinable, in determining the present value of lease payments. Our leases generally do not provide an implicit rate. Therefore, we use a collateralized incremental borrowing rate that incorporates information available at commencement date, including our company-specific interest rates from recent debt issuances, which we adjust to remove the LIBOR component in order to obtain our company-specific interest rate risk. We also leverage commercial mortgage-backed securities, or CMBS, rates, for transactions with similar values, origination dates, geographies and property types as the respective lease, which are adjusted using linear interpolation if the lease term falls between the published CMBS terms. As of June 30, 2021, our leases had a weighted-average discount rate of 10.8%. Our leases have remaining lease terms from approximately one year up to approximately seven years with a weighted-average remaining lease term of 4.8 as of June 30, 2021. As of June 30, 2021, we recognized an operating lease liability of $15.3 million and corresponding right-of-use asset of $9.3 million. Operating lease liabilities are included in other liabilities other assets We also sublease certain office space, resulting in sublease income. Sublease income and the related assets and cash flows are not material to our condensed consolidated financial statements as of and for the three and six months ended June 30, 2021. Sublease income is recognized as a reduction to operating lease expense in our condensed consolidated statements of operations and comprehensive loss. Future lease payments as of June 30, 2021 were as follows: Operating Leases (dollars in millions) Remainder of 2021 $ 2.0 2022 4.3 2023 4.4 2024 4.3 2025 1.5 2026 and thereafter 3.1 Total future lease payments 19.6 Less: imputed interest (4.3) Total lease liabilities $ 15.3 As previously disclosed in our 2020 10-K under the prior lease accounting guidance, the following table summarizes, by remaining maturity, future commitments related to operating leases and other arrangements as of December 31, 2020: Operating Leases (dollars in millions) 2021 $ 3.9 2022 4.4 2023 4.4 2024 4.3 2025 1.5 2026 and thereafter 3.1 Total $ 21.6

Debt Disclosure [Abstract]
LONG-TERM DEBT	LONG-TERM DEBT Term Loan A is a term loan we have outstanding with a group of syndicated financial institutions which matures on October 15, 2021. Interest is paid monthly and is determined on a floating interest rate calculated on the one-month LIBOR plus an applicable margin of 4%. As a part of the amended Term Loan A, the syndicate committed, pro rata, to a new $100 million revolving loan. Commitment fees accrue at 0.50% per annum on the daily amount of unused revolving loan and is paid quarterly. For any amounts drawn on the revolving loan, interest accrues and is paid consistent with Term Loan A. In addition, there is a letter of credit fee of 4% per annum on the average daily amount of issued letters of credit against the revolver and a 0.125% per annum fronting fee based on the average daily amount of letter of credit exposure. We have no letters of credit outstanding or amounts drawn against the revolving loan as of June 30, 2021. Term Loan B is a note we issued to a private equity investor that matures on November 25, 2024. Interest is determined on a floating interest rate calculated on the three-month LIBOR plus an applicable margin of 10.5%. We currently pay interest pursuant to the terms of the loan agreements and have the option to pay-in-kind, or PIK, on Term Loan B until October 15, 2021. PIK interest is added to the principal balance every three months until we no longer PIK interest, at which point interest is paid quarterly. We have elected to PIK interest on Term Loan B from the original date of closing through June 30, 2021. Deferred PIK interest was $3.4 million and $2.2 million for the three months ended June 30, 2021 and 2020, respectively. Deferred PIK interest was $5.8 million and $4.5 million for the six months ended June 30, 2021 and 2020, respectively. Deferred PIK interest is recognized as interest expense in the condensed consolidated statements of operations and comprehensive loss.

Except as disclosed below, we do not believe that we are party to any current or pending legal action that could reasonably be expected to have a material adverse effect on our financial condition or results of operations and cash flow. On March 19, 2021, a purported class action complaint was filed against the Company and certain of its current officers and directors in the U.S. District Court for the Southern District of Ohio (Case No. 2:21-cv-01197) on behalf of certain Root shareholders. The complaint alleges that defendants made false or misleading statements and omissions of purportedly material fact, in violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 thereunder, and of Sections 11 and 15 of the Securities Act of 1933, in connection with and following the Company’s initial public offering. The complaint seeks unspecified damages. The Company believes that the claims in this lawsuit are without merit and intends to defend against them vigorously. The lawsuit is in the early stages and, at this time, we are unable to predict the outcome and we cannot estimate the likelihood or magnitude of our possible or potential loss contingency. On March 25, 2021, a purported class action complaint was filed against the Company, certain of its current officers and directors, Goldman Sachs & Co. LLC, Morgan Stanley & Co.

SUBSEQUENT EVENTS	SUBSEQUENT EVENTS On August 11, 2021, we and Carvana (“CVNA”) announced an investment agreement, or agreement, to embed Root’s telematics-based auto insurance products into Carvana’s industry-leading, online car buying platform, or Integrated Platform. In connection with the agreement, Carvana will invest approximately $126 million of primary capital in a convertible preferred security, convertible at $9.00 per share, into approximately 14 million Class A shares of Root, or an ownership interest of 5.0% on a fully-diluted basis as of August 11, 2021. The agreement also includes eight tranches of warrants that will be issued to Carvana (three tranches of which are “short-term warrants” and five tranches of which are “long-term warrants”). The short-term warrants will expire three years following the earlier of the date of completion of the Integrated Platform or 18 months following closing (such earlier date, the “Reference Date”) and long-term warrants will expire five years after the Reference Date. The short-term warrants will have exercise prices of $10.00 to $12.00 and the long-term warrants will have exercise prices of $10.00 to $30.00. The warrants will be subject to certain conditions to exercise, including relating to the achievement of defined milestones tied to the development of the Integrated Platform and insurance sales through the Integrated Platform. These warrants would enable Carvana to acquire additional shares of Class A Common Stock, up to an amount representing 29.9% of the aggregate number of issued and outstanding shares of the Company’s common stock (including shares of the Company’s Class B common stock) on a fully-diluted basis as of August 11, 2021. The exclusive partnership includes a commercial arrangement incorporating agent commissions payable to Carvana for policy origination, and an enterprise total loss replacement vehicle solution. We plan to close the transaction during the second half of 2021, subject to customary regulatory approvals.

BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
	Jun. 30, 2021
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation —In our opinion, all adjustments necessary for a fair presentation of the condensed consolidated financial statements have been included. All such adjustments are of a normal and recurring nature. These condensed consolidated financial statements are unaudited and, accordingly, should be read in conjunction with the consolidated financial statements and related notes included in the Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC on March 4, 2021, or the 2020 10-K.
Basis of Consolidation	Basis of Consolidation—The unaudited condensed consolidated financial statements include the accounts of Root, Inc. and its subsidiaries, all of which are wholly owned. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States, or GAAP.
Use of Estimates	Use of Estimates —The preparation of the unaudited condensed consolidated financial statements requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates reflected in our unaudited condensed consolidated financial statements include, but are not limited to, reserves for loss and loss adjustment expense, premium write-offs and valuation allowances for income taxes.
Recently Adopted Financial Accounting Standards/Upcoming Accounting Pronouncements	Recently Adopted Financial Accounting Standards —In February 2016, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, No. 2016-02, Leases (Topic 842) . The main provision of ASU 2016-02 requires the recognition of right-of-use lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. The guidance also requires disclosures that meet the objective of enabling financial statement users to assess the amount, timing, and uncertainty of related cash flows. We adopted ASU 2016-02 on January 1, 2021. We elected various practical expedients which include: not applying the amended lease accounting guidance to comparative periods; including the carry forward of our leases without reassessing whether any contracts are leases or contain leases, lease classification and initial direct costs; and excluding leases with a term of 12 months or less from lease liability and right-of-use asset recognition. We did not elect the hindsight practical expedient. Our lease agreements contain lease components and non-lease components, both of which we have elected to account for as a single lease component for our real estate asset class. Operating lease expense for operating lease right-of-use assets is recognized on a straight-line basis over the lease term, which may include options to extend or terminate the lease when it is reasonably certain to do so and there is a significant economic incentive to exercise that option. Upon adoption of ASU 2016-02, we recognized an operating lease liability of $16.2 million and corresponding right-of-use asset of $9.9 million, which includes the effect of $6.3 million from reclassifying previously recognized deferred rent and lease exit liabilities as an offset, in accordance with the transition guidance. These lease assets and liabilities are recorded as other assets and other liabilities on the condensed consolidated balance sheets. This transition adjustment was reflected as a non-cash transaction in our condensed consolidated statements of cash flows. The transition did not have a material impact on our results of operations, liquidity or debt covenant compliance under our current debt agreements. For additional information refer to Note 6, “Leases.” Upcoming Accounting Pronouncements— We currently qualify as an "emerging growth company," or EGC, under the Jumpstart Our Business Startups Act of 2012, or JOBS Act, whereby we have the option to adopt new or revised accounting guidance within the same time periods as private companies. We have elected this option, but may ultimately determine it is preferable to take advantage of early adoption provisions offered within the applicable guidance. As of June 30, 2021, the market value of our common stock held by non-affiliates exceeded $700 million. We will follow the adoption criteria for public companies and reflect such adoption criteria in our Annual Report on Form 10-K for the 2021 fiscal year.
