Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Basis of Reporting and Accounting | BASIS OF REPORTING AND ACCOUNTING The accompanying consolidated financial statements include the accounts of The Progressive Corporation, our wholly owned insurance subsidiaries and non-insurance subsidiaries and affiliates in which we have a controlling financial interest (Progressive). The consolidated financial statements reflect all normal recurring adjustments that, in the opinion of management, were necessary for a fair statement of the results for the interim periods presented. The results of operations for the period ended September 30, 2023, are not necessarily indicative of the results expected for the full year. These consolidated financial statements and the notes thereto should be read in conjunction with Progressive’s audited financial statements and accompanying notes included in Exhibit 13 to our Annual Report on Form 10-K for the year ended December 31, 2022 (2022 Annual Report to Shareholders). Insurance Premiums and Receivables We perform analyses to evaluate our premiums receivable for expected credit losses. See our 2022 Annual Report to Shareholders for a discussion on our premiums receivable allowance for credit loss policy. The following table summarizes changes in our allowance for credit loss exposure on our premiums receivable: Three Months Ended September 30, Nine Months Ended September 30, (millions) 2023 2022 2023 2022 Allowance for credit losses, beginning of period $ 343.9 $ 265.8 $ 343.3 $ 280.4 Increase in allowance 1 157.5 130.9 399.7 320.6 Write-offs 2 (140.2) (101.7) (381.8) (306.0) Allowance for credit losses, end of period $ 361.2 $ 295.0 $ 361.2 $ 295.0 1 Represents the incremental increase in other underwriting expenses. 2 Represents the portion of the allowance that is reversed when premiums receivable are written off. Premiums receivable balances are written off once we have exhausted our collection efforts. Property and Equipment Included in other assets in our consolidated balance sheets are “held for sale” property. When property is transferred to held for sale, the property is written down to its fair value less estimated costs to sell the property. At September 30, 2023 and 2022, and December 31, 2022, we had held for sale property of $81.6 million, $47.4 million, and $48.7 million, respectively. Earnings Per Share Net income is reduced by preferred share dividends to determine net income available to common shareholders and is used in our calculation of the per common share amounts. Beginning March 15, 2023, the annual dividend rate for our Series B Preferred Shares switched to a floating rate. The floating nature of the dividend rate will impact the amount of the adjustment required to calculate net income available to common shareholders. See Note 9 – Dividends for further discussion. For periods when a net loss is reported, earnings per common share are calculated using basic average equivalent shares since diluted earnings per share would be antidilutive. New Accounting Standards During the first quarter 2023, the Financial Accounting Standards Board issued an Accounting Standards Update (ASU), which permits an election to amortize the cost of tax equity investments to the provision for income taxes if certain conditions are met. Currently, these investments are accounted for under the equity method of accounting. This ASU will be effective for fiscal years (including interim periods within those fiscal years) beginning after December 15, 2023 (2024 for calendar-year companies). If elected, this standard must be applied on either a modified retrospective or a retrospective basis. We intend to adopt the new standard under the modified retrospective basis, however, we do not expect this standard to have a material impact on our financial condition or results of operations. |

Investments | INVESTMENTS The following tables present the composition of our investment portfolio by major security type. Our securities are reported in our consolidated balance sheets at fair value. The changes in fair value for our fixed-maturity securities (other than hybrid securities) are reported as a component of accumulated other comprehensive income (loss), net of deferred income taxes, in our consolidated balance sheets. The net holding period gains (losses) reported below represent the inception-to-date changes in fair value for the hybrid and equity securities. The changes in the net holding period gains (losses) between periods are recorded as a component of net realized gains (losses) on securities in our consolidated statements of comprehensive income.

The total fair value of the portfolio at September 30, 2023 and 2022, and December 31, 2022, included $4.1 billion, $4.2 billion, and $4.4 billion, respectively, of securities held in a consolidated, non-insurance subsidiary of the holding company, net of unsettled security transactions. At September 30, 2023, bonds and certificates of deposit in the principal amount of $612.4 million were on deposit to meet state insurance regulatory requirements. We did not hold any securities of any one issuer, excluding U.S. government obligations, with an aggregate cost or fair value exceeding 10% of total shareholders’ equity at September 30, 2023 or 2022, or December 31, 2022. At September 30, 2023, we did not hold any debt securities that were non-income producing during the preceding 12 months. Short-Term Investments Our short-term investments may include commercial paper and other investments that are expected to mature or are redeemable within one year. We did not have any open repurchase or reverse repurchase transactions positions at September 30, 2023 and 2022, or December 31, 2022, and did not enter into any such transactions during the first nine months of 2023. During 2022, however, we did invest in repurchase transactions that had an immaterial impact on our results of operations and cash flows. To the extent we enter into repurchase or reverse repurchase transactions, consistent with past practice, we would elect not to offset these transactions and would report them on a gross basis in our consolidated balance sheets, despite the option to elect to offset these transactions as long as they were with the same counterparty and subject to an enforceable master netting arrangement. Hybrid Securities Certain securities in our fixed-maturity portfolio are accounted for as hybrid securities because they contain embedded derivatives that are not deemed to be clearly and closely related to the host investments. These securities are reported at fair value: September 30, (millions) 2023 2022 Dec. 31, 2022 Fixed Maturities: Corporate debt securities $ 511.1 $ 500.4 $ 535.4 Residential mortgage-backed securities 410.8 550.8 509.6 Other asset-backed securities 19.4 51.4 42.0 Redeemable preferred stocks 136.4 133.0 134.7 Total hybrid securities $ 1,077.7 $ 1,235.6 $ 1,221.7 Since the embedded derivatives (e.g., change-in-control put option, debt-to-equity conversion, or any other feature unrelated to the credit quality or risk of default of the issuer that could impact the amount or timing of our expected future cash flows) do not have observable intrinsic values, we use the fair value option to record the changes in fair value of these securities through income as a component of net realized gains or losses. Fixed Maturities The composition of fixed maturities by maturity at September 30, 2023, was: (millions) Cost Fair Value Less than one year $ 9,639.9 $ 9,387.8 One to five years 37,572.4 35,419.0 Five to ten years 13,197.7 11,710.3 Ten years or greater 80.6 74.8 Total $ 60,490.6 $ 56,591.9 Asset-backed securities are classified in the maturity distribution table based upon their projected cash flows. All other securities that do not have a single maturity date are reported based upon expected average maturity. Contractual maturities may differ from expected maturities because the issuers of the securities may have the right to call or prepay obligations.

Additionally, we had 14 securities in other fixed-maturity sectors that had their credit ratings downgraded, with a combined fair value of $144.2 million and an unrealized loss of $7.1 million as of September 30, 2023. A review of the securities in an unrealized loss position indicated that the issuers were current with respect to their interest obligations and that there was no evidence of deterioration of the current cash flow projections that would indicate we would not receive the remaining principal at maturity. Allowance For Credit and Uncollectible Losses We are required to measure the amount of potential credit losses for all fixed-maturity securities in an unrealized loss position. We did not record any allowances for credit losses or any write-offs for amounts deemed to be uncollectible during the first nine months of 2023 or 2022, and did not have a material credit loss allowance balance as of September 30, 2023 and 2022, or December 31, 2022. We considered several factors and inputs related to the individual securities as part of our analysis. The methodology and significant inputs used to measure the amount of credit losses in our portfolio included: • current performance indicators on the business model or underlying assets (e.g., delinquency rates, foreclosure rates, and default rates); • credit support (via current levels of subordination); • historical credit ratings; and • updated cash flow expectations based upon these performance indicators. In order to determine the amount of credit loss, if any, we initially reviewed securities in a loss position to determine whether it was likely that we would be required, or intended, to sell any of the securities prior to the recovery of their respective cost bases (which could be maturity). If we were likely to, or intended to, sell prior to a potential recovery, we would write off the unrealized loss. For those securities that we determined we were not likely to, or did not intend to, sell prior to a potential recovery, we performed additional analysis to determine if the loss was credit related. For securities subject to credit related loss, we calculated the net present value (NPV) of the cash flows expected (i.e., expected recovery value) using the current book yield for each security. The NPV was then compared to the security’s current amortized value to determine if a credit loss existed. In the event that the NPV was below the amortized value, and the amount was determined to be material individually, or in the aggregate, a credit loss would be deemed to exist, and either an allowance for credit losses would be created, or if an allowance currently existed, either a recovery of the previous allowance, or an incremental loss, would be recorded to net realized gains (losses) on securities. As of September 30, 2023 and 2022, and December 31, 2022, we believe none of the unrealized losses were related to material credit losses on any individual security, or in the aggregate. We continue to expect all the securities in our portfolio to pay their principal and interest obligations. In addition, we reviewed our accrued investment income outstanding on those securities in an unrealized loss position at September 30, 2023 and 2022, and December 31, 2022, to determine if the accrued interest amounts were determined to be uncollectible. Based on our analysis, we believe the issuers have sufficient liquidity and capital reserves to meet their current interest, and future principal, obligations and, therefore, did not write off any accrued income as uncollectible at September 30, 2023 and 2022, or December 31, 2022.

For the first nine months of both 2023 and 2022, the gross gains in common equities reflected sales of securities, as part of our plan to incrementally reduce risk in the portfolio in response to our view of the potential of a more difficult economic environment in both years. The gross loss from the fixed-maturity sales reflected the continued rise in interest rates throughout 2022, which resulted in valuation declines for most of our available-for-sale securities. In addition, during 2023, we selectively sold securities, which were primarily corporate debt securities and commercial mortgage-backed securities. The gross loss incurred in our nonredeemable preferred stocks was primarily related to the sale of certain holdings in U.S. bank preferred stocks. The other asset gain for 2023, related to proceeds received as the result of litigation in conjunction with three renewable energy investments we made from 2016 through 2018 (the original investments were previously written down in full). The other asset impairment loss was recorded as a result of our investment in a federal new markets tax credit fund, which was entered into during the second quarter 2021, and is reported in other assets in our consolidated balance sheets.

The increases are primarily due to an increase in interest rates on floating-rate securities in our portfolio, an increase in average assets resulting from premium growth, and investing new cash and cash from maturities in higher interest rate securities given the rising interest rate environment. |

Fair Value Disclosures [Abstract] | |
Fair Value | FAIR VALUE We have categorized our financial instruments, based on the degree of subjectivity inherent in the method by which they are valued, into a fair value hierarchy of three levels, as follows: • Level 1 : Inputs are unadjusted, quoted prices in active markets for identical instruments at the measurement date (e.g., U.S. government obligations, which are continually priced on a daily basis, active exchange-traded equity securities, and certain short-term securities). • Level 2 : Inputs (other than quoted prices included within Level 1) that are observable for the instrument either directly or indirectly (e.g., certain corporate and municipal bonds and certain preferred stocks). This includes: (i) quoted prices for similar instruments in active markets, (ii) quoted prices for identical or similar instruments in markets that are not active, (iii) inputs other than quoted prices that are observable for the instruments, and (iv) inputs that are derived principally from or corroborated by observable market data by correlation or other means. • Level 3 : Inputs that are unobservable. Unobservable inputs reflect our subjective evaluation about the assumptions market participants would use in pricing the financial instrument (e.g., certain structured securities and privately held investments). Determining the fair value of the investment portfolio is the responsibility of management. As part of that responsibility, we evaluate whether a market is distressed or inactive in determining the fair value for our portfolio. We review certain market level inputs to evaluate whether sufficient activity, volume, and new issuances exist to create an active market. Based on this evaluation, we concluded that there was sufficient activity related to the sectors and securities for which we obtained valuations.

Our short-term investments classified as Level 1 are highly liquid, actively marketed, and have a very short duration, primarily 90 days or less to redemption. These securities are held at their original cost, adjusted for any accretion of discount, since that value very closely approximates what an active market participant would be willing to pay for such securities. The remainder of our short-term investments are classified as Level 2 and are not priced externally since these securities continually trade at par value. These securities are classified as Level 2 since they are primarily longer-dated securities issued by municipalities that contain either liquidity facilities or mandatory put features within one year. At September 30, 2023, vendor-quoted prices represented 93% of our Level 1 classifications (excluding short-term investments), compared to 90% at both September 30, 2022 and December 31, 2022. The securities quoted by vendors in Level 1 primarily represent our holdings in U.S. Treasury Notes, which are frequently traded, and the quotes are considered similar to exchange-traded quotes. The balance of our Level 1 pricing comes from quotes obtained directly from trades made on active exchanges. All Level 1 preferred stocks with active exchange quotes were sold as of September 30, 2023. At September 30, 2023, vendor-quoted prices comprised 99% of our Level 2 classifications (excluding short-term investments and common stock), while dealer-quoted prices represented the remaining 1%, compared to 98% and 2%, respectively, at both September 30, 2022 and December 31, 2022. In our process for selecting a source (e.g., dealer or pricing service) to provide pricing for securities in our portfolio, we reviewed documentation from the sources that detailed the pricing techniques and methodologies used by these sources and determined if their policies adequately considered market activity, either based on specific transactions for the particular security type or based on modeling of securities with similar credit quality, duration, yield, and structure that were recently transacted. Once a source is chosen, we continue to monitor any changes or modifications to their processes by reviewing their documentation on internal controls for pricing and market reviews. We review quality control measures of our sources as they become available to determine if any significant changes have occurred from period to period that might indicate issues or concerns regarding their evaluation or market coverage. As part of our pricing procedures, we obtain quotes from more than one source to help us fully evaluate the market price of securities. However, our internal pricing policy is to use a consistent source for individual securities in order to maintain the integrity of our valuation process. Quotes obtained from the sources are not considered binding offers to transact. Under our policy, when a review of the valuation received from our selected source appears to be outside of what is considered market level activity (which is defined as trading at spreads or yields significantly different than those of comparable securities or outside the general sector level movement without a reasonable explanation), we may use an alternate source’s price. To the extent we determine that it may be prudent to substitute one source’s price for another, we will contact the initial source to obtain an understanding of the factors that may be contributing to the significant price variance. To allow us to determine if our initial source is providing a price that is outside of a reasonable range, we review our portfolio pricing on a weekly basis. When necessary, we challenge prices from our sources when a price provided does not match our expectations based on our evaluation of market trends and activity. Initially, we perform a review of our portfolio by sector to identify securities whose prices appear outside of a reasonable range. We then perform a more detailed review of fair values for securities disclosed as Level 2. We review dealer bids and quotes for these and/or similar securities to determine the market level context for our valuations. We then evaluate inputs relevant for each class of securities disclosed in the preceding hierarchy tables. For structured debt securities, including commercial, residential, and other asset-backed securities, we evaluate available market-related data for these and similar securities related to collateral, delinquencies, and defaults for historical trends and reasonably estimable projections, as well as historical prepayment rates and current prepayment assumptions and cash flow estimates. We further stratify each class of our structured debt securities into more finite sectors (e.g., planned amortization class, first pay, second pay, senior, subordinated, etc.) and use duration, credit quality, and coupon to determine if the fair value is appropriate. For corporate debt and preferred stock (redeemable and nonredeemable) portfolios, as well as the notes issued by The Progressive Corporation (see Note 4 – Debt ), we review securities by duration, credit quality, and coupon, as well as changes in interest rate and credit spread movements within that stratification. The review also includes recent trades, including: volume traded at various levels that establish a market; issuer specific fundamentals; and industry-specific economic news as it comes to light. For municipal securities (e.g., general obligations, revenue, and housing), we stratify the portfolio to evaluate securities by type, duration, credit quality, and coupon to review price changes relative to credit spread and interest rate changes. Additionally, we look to economic data as it relates to geographic location as an indication of price-to-call or maturity predictors. For municipal housing securities, we look to changes in cash flow projections, both historical and reasonably estimable projections, to understand yield changes and their effect on valuation. For short-term securities, we look at acquisition price relative to the coupon or yield. Since our short-term securities are typically 90 days or less to maturity, with the majority listed in Level 2 being 30 days or less to redemption, we believe that acquisition price is the best estimate of fair value. We also review data assumptions as supplied by our sources to determine if that data is relevant to current market conditions. In addition, we independently review each sector for transaction volumes, new issuances, and changes in spreads, as well as the overall movement of interest rates along the yield curve to determine if sufficient activity and liquidity exists to provide a credible source for our market valuations. During each valuation period, we create internal estimations of portfolio valuation (performance returns), based on current market-related activity (i.e., interest rate and credit spread movements and other credit-related factors) within each major sector of our portfolio. We compare our internally generated portfolio results with those generated based on quotes we receive externally and research material valuation differences. We compare our results to index returns for each major sector adjusting for duration and credit quality differences to better understand our portfolio’s results. Additionally, we review on a monthly basis our external sales transactions and compare the actual final market sales prices to previous market valuation prices. This review provides us further validation that our pricing sources are providing market level prices, since we are able to explain significant price changes (i.e., greater than 2%) as known events occur in the marketplace and affect a particular security’s price at sale. This analysis provides us with additional comfort regarding the source’s process, the quality of its review, and its willingness to improve its analysis based on feedback from clients. We believe this effort helps ensure that we are reporting the most representative fair values for our securities. After all the valuations are received and our review of Level 2 securities is complete, if the inputs used by vendors are determined to not contain sufficient observable market information, we will reclassify the affected securities to Level 3. Except as described below, our Level 3 securities are priced externally; however, due to several factors (e.g., nature of the securities, level of activity, and lack of similar securities trading to obtain observable market level inputs), these valuations are more subjective in nature. To the extent we receive prices from external sources (e.g., broker, valuation firm) for the Level 3 securities, we review those prices for reasonableness using internally developed assumptions and then compare our derived prices to the prices received from the external sources. Based on our review, all prices received from external sources remained unadjusted. If we do not receive prices from an external source, we perform an internal fair value comparison, which includes a review and analysis of market-comparable securities, to determine if fair value changes are needed. Based on this analysis, certain private equity investments included in the Level 3 category remain valued at cost or were priced using a recent transaction as the basis for fair value. At least annually, these private equity investments are priced by an external source. Our Level 3 other risk investments include securities accounted for under the equity method of accounting and, therefore, are not subject to fair value reporting. Since these securities represent less than 0.1% of our total portfolio, we will continue to include them in our Level 3 disclosures and report the activity from these investments as “other” changes in the summary of changes in fair value table and categorize these securities as “pricing exemption securities” in the quantitative information table. One of our Level 3 financial nonredeemable preferred stocks was exchanged into common equity during third quarter 2023 and the security was sold prior to September 30, 2023. The Level 2 common stock held at September 30, 2022, was transferred to Level 3 at December 31, 2022. At September 30, 2023 and 2022, and December 31, 2022, we did not have any securities in our fixed-maturity portfolio listed as Level 3. During the first nine months of 2023 and 2022, there were no material assets or liabilities measured at fair value on a nonrecurring basis, other than goodwill. See Note 12 – Goodwill and Intangible Assets for further discussion. Due to the relative size of the Level 3 securities’ fair values compared to the total portfolio’s fair value, any changes in pricing methodology would not have a significant change in valuation that would materially impact net or comprehensive income.

The net proceeds from the issuance, after deducting underwriters’ discounts, commissions, and other issuance costs, was approximately $496.3 million. Consistent with the other senior notes issued by Progressive, interest on this note is payable semiannually, principal is due at maturity, and the note is redeemable, in whole or in part, at any time, subject to a treasury “make whole” provision. There was no short-term debt outstanding at September 30, 2023 and 2022, and December 31, 2022. During the second quarter 2023, The Progressive Corporation amended its line of credit with PNC Bank, National Association (PNC), to increase the maximum principal amount to $300 million from the previous amount of $250 million and extend the expiration date to April 30, 2024. Subject to the terms and conditions of the line of credit documents, advances under the line of credit (if any) will bear interest at a variable rate equal to the 1-month term Secured Overnight Financing Rate (SOFR) plus 1.10%. Each advance must be repaid on the 30th day after the date of the advance or, if earlier, April 30, 2024, the expiration date of the line of credit. Prepayments are permitted without penalty. The line of credit is uncommitted and, as such, all advances are subject to PNC’s discretion. We had no borrowings under the line of credit during the periods presented. |

Income Tax Disclosure [Abstract] | |
Income Taxes | INCOME TAXESDeferred tax assets and liabilities are recorded based on the difference between the financial statement and tax bases of assets and liabilities at the enacted tax rates. We review our deferred tax assets regularly for recoverability. At September 30, 2023 and 2022, and December 31, 2022, we determined that we did not need a valuation allowance on our gross deferred tax assets. Although realization of the deferred tax assets is not assured, management believes that it is more likely than not the deferred tax assets will be realized based on our expectation that we will be able to fully utilize the deductions that are ultimately recognized for tax purposes. At September 30, 2023 and 2022, and December 31, 2022, the net deferred tax asset includes a gross deferred tax asset of $807.0 million, $827.7 million, and $742.9 million, respectively, related to unrealized losses on fixed-maturity securities. We believe this deferred tax asset will be realized based on the existence of prior year capital gains, current temporary differences related to unrealized gains in our equity portfolio, and other tax planning strategies. At September 30, 2023 and 2022, and December 31, 2022, we had no reserves for uncertain tax positions. The effective tax rate for the three and nine months ended September 30, 2023, was 20.5% and 20.2%, respectively, compared to 12.9% and (1.6)% for the same periods last year. The lower effective tax rates for the three and nine months ended September 30, 2022, were due in part to the low amount of income (loss) before taxes during those periods, resulting in permanent tax differences having a greater impact on the effective rate. The low effective tax rate for the nine months ended September 30, 2022, was also due to a goodwill impairment charge (see Note 12 – Goodwill and Intangible Assets for further discussion). |

Loss and Loss Adjustment Expense Reserves | LOSS AND LOSS ADJUSTMENT EXPENSE RESERVES Activity in the loss and loss adjustment expense reserves is summarized as follows: September 30, (millions) 2023 2022 Balance at January 1 $ 30,359.3 $ 26,164.1 Less reinsurance recoverables on unpaid losses 5,559.2 4,733.6 Net balance at January 1 24,800.1 21,430.5 Incurred related to: Current year 33,035.0 28,245.4 Prior years 1,147.0 52.8 Total incurred 34,182.0 28,298.2 Paid related to: Current year 18,581.3 15,712.4 Prior years 11,764.7 9,418.5 Total paid 30,346.0 25,130.9 Net balance at September 30 28,636.1 24,597.8 Plus reinsurance recoverables on unpaid losses 4,941.2 6,034.0 Balance at September 30 $ 33,577.3 $ 30,631.8 We experienced unfavorable reserve development of $1,147.0 million and $52.8 million during the first nine months of 2023 and 2022, respectively, which is reflected as “incurred related to prior years ” in the table above. Year-to-date September 30, 2023 • The unfavorable prior year reserve development included approximately $929 million attributable to accident year 2022, $108 million to accident year 2021, and the remainder to accident years 2020 and prior. • Our perso nal auto products incurred about $866 million of unfavorable loss and loss adjustment expense (LAE) reserve development, with the Agency and Direct auto businesses each contributing about half. Over half of the unfavorable development was attributable to higher than anticipated severity in auto property and physical damage coverages, while the remaining unfavorable development was primarily due to increased loss costs in Florida injury and medical coverages and, to a lesser extent, higher than anticipated late reported injury claims; partially offset by lower than expected loss adjustment expenses. • Our Commercial Lines business experienced about $277 million of unfavorable development, primarily driven by higher than anticipated severity and frequency of late reported injury claims, with about half of the unfavorable development attributable to our transportation network company (TNC) business. Year-to-date September 30, 2022 • Approximately $45 million of the unfavorable prior year reserve development was attributable to accident year 2021 and $29 million to 2019 and prior accident years, partially offset by $21 million of favorable development attributable to accident year 2020. • Our personal auto products incurred about $28 million of favorable loss and LAE reserve development, with about $25 million attributable to the Direct business. The favorable development was primarily attributable to more subrogation and salvage recoveries and lower LAE than originally anticipated, partially offset by higher than anticipated severity and frequency of auto property damage payments on previously closed claims and late reported injury claims. • Our Commercial Lines business experienced about $77 million of unfavorable development, primarily due to higher than anticipated severity of injury case reserves and higher than anticipated severity and frequency of late reported claims in our TNC business. |

Segment Reporting [Abstract] | |
Segment Information | SEGMENT INFORMATION Our Personal Lines segment writes insurance for personal autos and recreational vehicles (our special lines products). Our Commercial Lines segment writes auto-related liability and physical damage insurance, business-related general liability and property insurance predominately for small businesses, and workers’ compensation insurance primarily for the transportation industry. Our Property segment writes residential property insurance for homeowners, other property owners, and renters. Our service businesses provide insurance-related services, including serving as an agent for homeowners, general liability, and workers’ compensation insurance, among other products, through programs in our direct Personal Lines and Commercial Lines businesses. As previously disclosed in our 2022 Annual Report to Shareholders, during 2022, our contract to act as a servicing agent for processing Commercial Automobile Insurance Procedures/Plans (CAIP) business expired during the third quarter 2022 and we did not renew the contract. This non-renewal did not materially affect our financial condition, results of operations, or cash flows. All segment revenues are generated from external customers; all intercompany transactions are eliminated in consolidation.

For the nine months ended September 30, 2022, the total pretax loss, including goodwill impairment, for the Property segment was $514.4 million. See Note 12 – Goodwill and Intangible Assets for further discussion. 3 Includes other underwriting business and run-off operations. 4 Pretax profit (loss) for fees and other revenues is allocated to operating segments based on revenue. 5 Revenues represent recurring investment income and total net realized gains (losses) on securities; pretax profit (loss) is net of investment expenses. Our management uses underwriting margin and combined ratio as primary measures of underwriting profitability. The underwriting margin is the pretax underwriting profit (loss) expressed as a percentage of net premiums earned (i.e., revenues from underwriting operations). Pretax underwriting profit (loss) is calculated as net premiums earned plus fees and other revenues, less: (i) losses and loss adjustment expenses; (ii) policy acquisition costs; and (iii) other underwriting expenses. Combined ratio is the complement of the underwriting margin.

Beginning March 15, 2023, the annual dividend rate for our Series B Preferred Shares switched to a floating rate equal to the three-month London Interbank Offered Rate (LIBOR) plus a spread of 2.539% applied to the stated amount per share. We, as calculation agent under our Series B Preferred Shares, determined that the reference rate for the Series B Preferred Shares, for any determination date after June 30, 2023, shall be the sum of (i) 3-Month CME Term SOFR plus (ii) a tenor spread adjustment of 0.26161%, and (iii) a spread of 2.539%. The new reference rate became effective for the dividend period determination date commencing September 15, 2023. The reference rate was determined in accordance with the successor base rate provisions of the Series B Preferred Shares and the Adjustable Interest Rate (LIBOR) Act and the regulation issued by the Board of Governors of the Federal Reserve System on December 16, 2022, implementing the LIBOR Act. During the floating rate period, dividends on the Series B Preferred Shares will be payable quarterly, if and when declared by the Board of Directors. See Note 14 – Dividends in our 2022 Annual Report to Shareholders for a discussion of our quarterly and annual common share dividends and our preferred share dividend policies. |

As of September 30, 2023, lawsuits have been certified or conditionally certified as class/collective actions in cases alleging: we improperly reduce or deny UIM benefits in New Mexico; we improperly value total loss claims in Florida, Georgia, New York, Pennsylvania, and Washington; we improperly fail to pay fees and taxes associated with total losses in Florida, Michigan, and New York; we improperly adjust medical bills in Washington; we improperly calculate basic economic loss as it relates to wage loss coverage in New York; we improperly fail to timely process and pay PIP claims in Texas; we improperly reduce or deny first-party medical benefits in Arkansas; and that certain of our compensation practices and overtime payment practices are improper, including our classification of certain employees as exempt from overtime pay requirements. Other insurance companies face many of these same issues. The nature and volume of litigation pending against The Progressive Corporation and/or its insurance subsidiaries is similar to that which was disclosed in Note 12 – Litigation in our 2022 Annual Report to Shareholders. We plan to contest the pending lawsuits vigorously, but may pursue settlement negotiations in some cases, as we deem appropriate. Although outcomes of pending cases are uncertain until final disposition, we establish accruals for these lawsuits when it is probable that a loss has been or will be incurred and we can reasonably estimate potential loss exposure, which may include a range of loss. As to lawsuits for which the loss is considered neither probable nor estimable, or is considered probable but not estimable, we do not establish an accrual. Nevertheless, we continue to evaluate pending litigation to determine if any losses not deemed probable and estimable become so, at which point we would establish an accrual at our best estimate of the loss or range of loss. With respect to our pending lawsuits that are not related to claims under insurance policies, the accruals that we have established, if any, were not material at September 30, 2023 and 2022, or December 31, 2022, and there were no material settlements during 2022 or the first nine months of 2023. For most of these lawsuits, we do not consider any losses to be both probable and estimable, and we are unable to estimate a meaningful range of loss, if any, at this time, due to the factors discussed in Note 12 – Litigation in our 2022 Annual Report to Shareholders. In the event that any one or more of these lawsuits results in a substantial judgment against us, or settlement by us, or if our accruals (if any) prove to be inadequate by a significant amount, the resulting liability could have a material adverse effect on our consolidated financial condition, cash flows, and/or results of operations. For a further discussion on our pending litigation and related reserving policies, see Note 12 – Litigation in our 2022 Annual Report to Shareholders. |

Goodwill and Intangible Assets Disclosure [Abstract] | |
Goodwill and Intangible Assets | GOODWILL AND INTANGIBLE ASSETS Goodwill The majority of the goodwill recorded as of September 30, 2023 and 2022, and December 31, 2022, related to the April 1, 2015, acquisition of a controlling interest in ARX Holding Corp. (ARX). During the nine months ended September 30, 2023, there were no changes to the carrying amount of goodwill. In the second quarter 2022, we performed an interim impairment test of our goodwill allocated to the ARX reporting unit and recorded an impairment loss of $224.8 million . The impairment loss was fully allocated to our Property operating segment. There were no previously recorded goodwill impairment losses on any of the outstanding goodwill. See Note 15 – Goodwill and Intangible Assets in our 2022 Annual Report to Shareholders for a discussion of our goodwill impairment evaluation. Intangible Assets The following table is a summary of the net carrying amount of other intangible assets: (millions) September 30, 2023 September 30, 2022 December 31, 2022 Intangible assets subject to amortization $ 62.5 $ 79.4 $ 73.9 Indefinite-lived intangible assets 1 12.4 12.4 12.4 Total $ 74.9 $ 91.8 $ 86.3 1 Indefinite-lived intangible assets are comprised of state insurance and agent licenses.

Earnings Per Share | Earnings Per ShareNet income is reduced by preferred share dividends to determine net income available to common shareholders and is used in our calculation of the per common share amounts. |
New Accounting Standards | New Accounting Standards During the first quarter 2023, the Financial Accounting Standards Board issued an Accounting Standards Update (ASU), which permits an election to amortize the cost of tax equity investments to the provision for income taxes if certain conditions are met. Currently, these investments are accounted for under the equity method of accounting. This ASU will be effective for fiscal years (including interim periods within those fiscal years) beginning after December 15, 2023 (2024 for calendar-year companies). If elected, this standard must be applied on either a modified retrospective or a retrospective basis. We intend to adopt the new standard under the modified retrospective basis, however, we do not expect this standard to have a material impact on our financial condition or results of operations. |
