Accounting Policies [Abstract]
Accounting Policies	Accounting Policies The condensed consolidated financial statements include the accounts of Cincinnati Financial Corporation and its consolidated subsidiaries, each of which is wholly owned. These statements are presented in conformity with accounting principles generally accepted in the United States of America (GAAP). All intercompany balances and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes. Our actual results could differ from those estimates. Certain financial information that is normally included in annual financial statements prepared in accordance with GAAP, but that is not required for interim reporting purposes, has been condensed or omitted. Our September 30, 2021, condensed consolidated financial statements are unaudited. We believe that we have made all adjustments, consisting only of normal recurring accruals, that are necessary for fair presentation. These condensed consolidated financial statements should be read in conjunction with our consolidated financial statements included in our 2020 Annual Report on Form 10-K. The results of operations for interim periods do not necessarily indicate results to be expected for the full year. Beginning in mid-March 2020, the coronavirus (SARS-CoV-2 or COVID-19) pandemic outbreak, and unprecedented actions taken to contain the virus, caused an economic downturn on a global scale as well as market disruption and volatility. The company continues to monitor the impact of the pandemic as it unfolds. The company cannot predict the impact the pandemic will have on its future consolidated financial position, results of operations and cash flows, however the impact could be material. Pending Accounting Updates ASU 2018-12, Financial Services - Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts In August 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2018-12, Financial Services - Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts. ASU 2018-12 is intended to improve the timeliness of recognizing changes in the liability for future policy benefits and modify the rate used to discount future cash flows. The ASU will simplify and improve the accounting for certain market-based options or guarantees associated with deposit or account balance contracts and simplify amortization of deferred acquisition costs while improving and expanding required disclosures. In November 2020, the FASB issued an ASU that delayed the effective date of ASU 2018-12 to interim and annual reporting periods beginning after December 15, 2022. These ASUs have not yet been adopted. Management is currently evaluating the impact on our company's consolidated financial position, results of operations and cash flows.

Fair Value Measurements

Fair Value Measurements	Sep. 30, 2021
Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements In accordance with accounting guidance for fair value measurements and disclosures, we categorized our financial instruments, based on the priority of the observable and market-based data for the valuation technique used, into a three-level fair value hierarchy. The fair value hierarchy gives the highest priority to quoted prices with readily available independent data in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable market inputs (Level 3). When various inputs for measurement fall within different levels of the fair value hierarchy, the lowest observable input that has a significant impact on fair value measurement is used. Our valuation techniques have not changed from those used at December 31, 2020, and ultimately management determines fair value. See our 2020 Annual Report on Form 10-K, Item 8, Note 3, Fair Value Measurements, Page 143, for information on characteristics and valuation techniques used in determining fair value. Fair Value Disclosures for Assets The following tables illustrate the fair value hierarchy for those assets measured at fair value on a recurring basis at September 30, 2021 and December 31, 2020.

The actuarial estimate is subject to review and adjustment by an inter-departmental committee that includes actuarial, claims, underwriting, loss prevention and accounting management. This committee is familiar with relevant company and industry business, claims and underwriting trends, as well as general economic and legal trends that could affect future loss and loss expense payments. The amount we will actually have to pay for claims can be highly uncertain. This uncertainty, together with the size of our reserves, makes the loss and loss expense reserves our most significant estimate. The reserve for loss and loss expenses in the condensed consolidated balance sheets also included $66 million at September 30, 2021 and For the three months ended September 30, 2021, we experienced $102 million of favorable development on prior accident years, including $107 million of favorable development in commercial lines, $3 million of favorable development in personal lines and $3 million of unfavorable development in excess and surplus lines. Within commercial lines, we recognized favorable reserve development of $52 million for the commercial casualty line and $34 million for the commercial property line due to reduced uncertainty of prior accident year loss and loss adjustment expense for these lines. For the nine months ended September 30, 2021, we experienced $331 million of favorable development on prior accident years, including $276 million of favorable development in commercial lines, $35 million of favorable development in personal lines and $6 million of unfavorable development in excess and surplus lines. Within commercial lines, we recognized favorable reserve development of $85 million for the commercial casualty line, $68 million for the commercial property line, $59 million for the workers' compensation line and $44 million for the commercial auto line due to reduced uncertainty of prior accident year loss and loss adjustment expense for these lines. Within personal lines, we recognized favorable reserve development of $24 million in personal auto.

Liability for Future Policy Benefit, before Reinsurance [Abstract]
Life Policy And Investment Contract Reserves	Life Policy and Investment Contract Reserves We establish the reserves for traditional life insurance policies based on expected expenses, mortality, morbidity, withdrawal rates, timing of claim presentation and investment yields, including a provision for uncertainty. Once these assumptions are established, they generally are maintained throughout the lives of the contracts. We use both our own experience and industry experience, adjusted for historical trends, in arriving at our assumptions for expected mortality, morbidity and withdrawal rates as well as for expected expenses. We base our assumptions for expected investment income on our own experience adjusted for current and future economic conditions. We establish reserves for the company's deferred annuity, universal life and structured settlement policies equal to the cumulative account balances, which include premium deposits plus credited interest less charges and withdrawals. Some of our universal life policies contain no-lapse guarantee provisions. For these policies, we establish a reserve in addition to the account balance, based on expected no-lapse guarantee benefits and expected policy assessments.

We continue to believe that after considering all positive and negative evidence of taxable income in the carryback and carryforward periods as permitted by law, it is more likely than not that all of the deferred tax assets on our U.S. domestic operations will be realized. As a result, we have no valuation allowance for our U.S. domestic operations at September 30, 2021, and December 31, 2020. As more fully discussed below, we do carry a valuation allowance on the deferred tax assets related to Cincinnati Global. Unrecognized Tax Benefits At September 30, 2021, and December 31, 2020, we had a gross unrecognized tax benefit of $34 million. There were no changes to this amount during the first nine months of 2021. It is reasonably possible that within the next 12 months, our unrecognized tax benefit could change when the IRS completes its examination of the tax year ended December 31, 2018. Cincinnati Global As a result of operations for the three months ended September 30, 2021, Cincinnati Global increased net deferred assets $4 million with an offsetting increase of $4 million to the valuation allowance. There was no change in the net deferred assets or valuation allowance for the nine months ended September 30, 2021. At September 30, 2021, Cincinnati Global had a net deferred tax asset of $56 million and an offsetting valuation allowance of $56 million. Deferred tax assets are reduced by a valuation allowance when management believes it is more likely than not that some, or all, of the deferred tax assets will not be realized. After considering all positive and negative evidence related to the Cincinnati Global operations, we continue to believe it is appropriate to carry a valuation allowance at September 30, 2021.

Commitments and Contingent Liabilities	Sep. 30, 2021
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments and Contingent Liabilities In the ordinary course of conducting business, the company and its subsidiaries are named as defendants in various legal proceedings. Most of these proceedings are claims litigation involving the company’s insurance subsidiaries in which the company is either defending or providing indemnity for third-party claims brought against insureds or litigating first-party coverage claims. The company accounts for such activity through the establishment of unpaid loss and loss expense reserves. We believe that the ultimate liability, if any, with respect to such ordinary-course claims litigation, after consideration of provisions made for potential losses and costs of defense, is immaterial to our consolidated financial position, results of operations and cash flows. Beginning in April 2020, like many companies in the property casualty insurance industry, the company’s property casualty subsidiaries, were named as defendants in lawsuits seeking insurance coverage under commercial property insurance policies issued by the company for alleged economic losses resulting from the shutdown or suspension of their businesses due to the COVID-19 pandemic. Although the allegations vary, the plaintiffs generally seek a declaration of insurance coverage, damages for breach of contract in unspecified amounts for claim denials, interest and attorney fees. Some of the lawsuits also allege that the insurance claims were denied in bad faith or otherwise in violation of state laws and seek extra-contractual or punitive damages. The company denies the allegations in these lawsuits and intends to continue to vigorously defend them. Although the policy terms vary, in general, the company denied the claims at issue in these lawsuits because the policyholder identified no direct physical loss or damage to property at the insured premises, and/or the governmental orders that led to the complete or partial shutdown of the business were not due to the existence of any direct physical loss or damage to property in the immediate vicinity of the insured premises and did not prohibit access to the insured premises, as required by the terms of the insurance policies. Additional policy terms and conditions may also prohibit coverage, such as exclusions for pollutants, ordinance or law, loss of use, and acts or decisions. The company’s standard commercial property insurance policies generally did not contain a specific virus exclusion. In addition to the inherent difficulty in predicting litigation outcomes, the COVID-19 pandemic business income coverage lawsuits present a number of uncertainties and contingencies that are not yet known, including how many policyholders will ultimately file claims, the number of lawsuits that will be filed, the extent to which any class may be certified, and the size and scope of any such classes. The legal theories advanced by plaintiffs vary by case, and the state laws that govern policy interpretation will guide judicial rulings on dispositive motions. These lawsuits are at various stages of litigation; many complaints continue to be amended; several have been dismissed voluntarily and may be refiled; others have been dismissed in favor of the company by trial courts; and a handful of cases are advancing toward trials. Many decisions on motion filings have been appealed. While these appeals are at various stages of the briefing and argument process, several of the cases are now fully briefed and are ripe for decision. The first two appellate cases in the nation to consider these issues were recently decided by the Federal Courts of Appeals for the Eighth and Eleventh Circuits in favor of the company, applying Iowa law and Georgia law, respectively. The Federal Courts of Appeals for the Sixth and Ninth Circuits also recently decided cases on these issues in favor of other insurers, applying Ohio law and California law, respectively. The company’s cases pending in trial courts in Ohio are stayed pending a decision by the Ohio Supreme Court on a question certified to it by the federal district court in the Northern District of Ohio in the case of Neuro-Communication Services, Inc. v. The Cincinnati Insurance Company, et al., Case No. 4:20-cv-1275 (N.D. Ohio filed June 10, 2020). The Ohio Supreme Court has agreed to answer the following question: “Does the general presence in the community, or on surfaces at a premises, of the novel coronavirus known as SARS-CoV-2, constitute direct physical loss or damage to property; or does the presence of a person infected with COVID-19 constitute direct physical loss or damage to property at that premises?" Because most of our pending cases remain in the early stages of motion practice or appeals from trial court rulings on dispositive motions, little discovery has occurred. In addition, business income calculations depend upon a wide range of factors that are particular to the circumstances of each individual policyholder and, here, the vast majority of plaintiffs have not submitted proofs of loss or otherwise quantified or factually supported any allegedly covered loss. Moreover, the company’s experience shows that demands stated in lawsuits often bear little relation to a reasonable estimate of potential loss. Accordingly, management cannot now reasonably estimate the possible loss or range of loss, if any. Nonetheless, given the number of claims and potential claims, the indeterminate amounts sought, and the inherent unpredictability of litigation, it is possible that adverse outcomes, if any, in the aggregate could have a material adverse effect on the company’s consolidated financial position, results of operations and cash flows. The company and its subsidiaries also are occasionally involved in other legal and regulatory proceedings, some of which assert claims for substantial amounts. These actions include, among others, putative class actions seeking certification of a national class. The company’s insurance subsidiaries also are occasionally parties to individual actions in which extra-contractual damages, punitive damages or penalties are sought, such as claims alleging bad faith handling of insurance claims or writing unauthorized coverage or claims alleging discrimination by former or current associates. On a quarterly basis, we review these outstanding matters. Under current accounting guidance, we establish accruals when it is probable that a loss has been incurred and we can reasonably estimate its potential exposure. The company accounts for such probable and estimable losses, if any, through the establishment of legal expense reserves. Based on our quarterly review, we believe that our accruals for probable and estimable losses are reasonable and that the amounts accrued do not have a material effect on our consolidated financial position, results of operations and cash flows. However, if any one or more of these matters results in a judgment against us or settlement for an amount that is significantly greater than the amount accrued, if any, the resulting liability could have a material effect on the company’s consolidated financial position, results of operations and cash flows. Based on our most recent review, our estimate for any other matters for which the risk of loss is not probable, but more than remote, is immaterial.

Accounting Policies [Abstract]
Adopted Accounting Updates and Pending Accounting Updates	Pending Accounting Updates ASU 2018-12, Financial Services - Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts In August 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2018-12, Financial Services - Insurance (Topic 944): Targeted Improvements to the Accounting for Long-Duration Contracts. ASU 2018-12 is intended to improve the timeliness of recognizing changes in the liability for future policy benefits and modify the rate used to discount future cash flows. The ASU will simplify and improve the accounting for certain market-based options or guarantees associated with deposit or account balance contracts and simplify amortization of deferred acquisition costs while improving and expanding required disclosures. In November 2020, the FASB issued an ASU that delayed the effective date of ASU 2018-12 to interim and annual reporting periods beginning after December 15, 2022. These ASUs have not yet been adopted. Management is currently evaluating the impact on our company's consolidated financial position, results of operations and cash flows.
