Summary Of Significant Accounti

Summary Of Significant Accounting Policies	3 Months Ended

Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation - The consolidated financial statements include the accounts of Capitol Federal Financial, Inc.® (the "Company") and its wholly-owned subsidiary, Capitol Federal Savings Bank (the "Bank"). The Bank has two wholly-owned subsidiaries, Capitol Funds, Inc. and Capital City Investments, Inc. Capitol Funds, Inc. has a wholly-owned subsidiary, Capitol Federal Mortgage Reinsurance Company. Capital City Investments, Inc. is a real estate and investment holding company. All intercompany accounts and transactions have been eliminated in consolidation. The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. These statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended September 30, 2019 , filed with the Securities and Exchange Commission ("SEC"). Interim results are not necessarily indicative of results for a full year. Cash, Cash Equivalents, Restricted Cash and Restricted Cash Equivalents - Cash, cash equivalents, restricted cash and restricted cash equivalents reported in the statement of cash flows include cash and cash equivalents of $70.7 million and $220.4 million at December 31, 2019 and September 30, 2019 , respectively, and restricted cash and cash equivalents of $26.6 million and $33.3 million at December 31, 2019 at September 30, 2019 , respectively, which was included in other assets on the consolidated balance sheet. The restricted cash and cash equivalents relate to the collateral postings to/from the Bank's derivative counterparties associated with the Bank's interest rate swaps. See additional discussion regarding the interest rate swaps in Note 5. Borrowed Funds. Net Presentation of Cash Flows Related to Borrowings - At times, the Bank enters into certain FHLB advances with contractual maturities of 90 days or less. Cash flows related to these advances are reported on a net basis in the consolidated statements of cash flows. There was no FHLB advance activity reported on a net basis in the consolidated statements of cash flows during the three months ended December 31, 2019 and 2018 . Leases - The Company leases real estate property for branches, ATMs, and certain equipment. All of the leases in which the Company is the lessee are classified as operating leases. The Company determines if an arrangement is a lease at inception and if the lease is an operating lease or a finance lease. Operating lease right-of-use assets represent the Company's right to use an underlying asset during the lease term and operating lease liabilities represent the Company's obligation to make lease payments arising from the lease. The right-of-use assets associated with operating leases are recorded in other assets in the Company's consolidated balance sheets. The lease liabilities associated with operating leases are included in accounts payable and accrued expenses on the consolidated balance sheets. The period over which the right-of-use asset is amortized is generally the lesser of the expected remaining term or the remaining useful life of the leased asset. The lease liability is decreased as periodic lease payments are made. The Company performs impairment assessments for right-of-use assets when events or changes in circumstances indicate that their carrying values may not be recoverable. The calculated amount of the right-of-use assets and lease liabilities are impacted by the length of the lease term and the discount rate used to calculate the present value of the minimum remaining lease payments. The Company's lease agreements often include one or more options to renew at the Company's discretion. If, at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company includes the extended term in the calculation of the right-of-use asset and lease liability. Generally, the Company cannot practically determine the interest rate implicit in the lease so the Company's incremental borrowing rate is used as the discount rate for the lease. The Company uses FHLB advance interest rates, which have been deemed as the Company's incremental borrowing rate, at lease inception based upon the term of the lease. For operating leases existing prior to October 1, 2019, the rate for the remaining lease term as of October 1, 2019 was applied. The Company's lease agreements do not contain any material residual value guarantees or material restrictive covenants. Lease expense, variable lease expense and short-term lease expense are included in occupancy expense in the Company's consolidated statements of income. For facility-related leases, the Company elected, by lease class, to not separate lease and non-lease components. Lease expense is recognized on a straight-line basis over the lease term. Variable lease expense primarily represents payments such as common area maintenance and utilities and are recognized as expense in the period when those payments are incurred. Short-term lease expense relates to leases with an initial term of 12 months or less. The Company has elected to not record a right-of-use asset or lease liability for short-term leases. Recent Accounting Pronouncements - In February 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-02, Leases . The ASU, as amended, revises lease accounting guidance by requiring that lessees recognize the assets and liabilities arising from leases on the balance sheet. Additionally, the ASU requires entities to disclose both quantitative and qualitative information regarding their leasing activities. The accounting applied by a lessor is largely unchanged from that applied under the previous guidance. In July 2018, the FASB issued ASU 2018-11, Leases , which provides entities with relief from the costs of implementation by allowing the option to not restate comparative periods as part of the transition. The ASU, as amended, became effective for the Company on October 1, 2019. Upon adoption, the Company elected the modified retrospective approach and the optional transition method under which the Company used the effective date as the date of initial application of the amendments. The optional practical expedients the Company elected include: (1) not reassessing whether any expired or existing contracts are or contain leases, (2) not reassessing the classification of any expired or existing contracts, (3) not reassessing initial direct costs for existing leases, and (4) using hindsight for leases existing at adoption date. For leases with an initial term of 12 months or less, the Company elected the short-term lease option, which entails not recognizing right-of-use assets and lease liabilities for these leases. Additionally, the Company elected, for facility-related leases, the practical expedient that allows an entity to elect, by lease class, the ability to not separate lease and non-lease components. Upon adoption, the Company recognized a right-of-use asset of $15.7 million and a lease liability of $15.5 million , related to the Company's non-cancellable operating lease commitments based on the present value of the expected remaining lease payments as of October 1, 2019. The cumulative-effect adjustment to retained earnings at the time of adoption totaled $88 thousand . These ASUs did not have a material impact on the Company's results of operations and cash flows at the time of adoption. The disclosures required by the ASU are included in Note 9. Leases. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments . The ASU, as amended, replaces the incurred loss impairment methodology in current GAAP, which requires credit losses to be recognized when it is probable that a loss has been incurred, with a new impairment methodology. The new impairment methodology requires an entity to measure, at each reporting date, the expected credit losses of financial assets not measured at fair value, such as loans and loan commitments, over their contractual lives. Under the new impairment methodology, expected credit losses will be measured at each reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Additionally, the ASU amends the current credit loss measurements for AFS debt securities. Credit losses related to AFS debt securities will be recorded through the ACL rather than as a direct write-down as per current GAAP. The ASU also requires enhanced disclosures related to credit quality and significant estimates and judgments used by management when estimating credit losses. The ASU will become effective for the Company on October 1, 2020. The Company continues to work with a software provider on the application and implementation of the new accounting guidance. The integration of the Company's data with the software provider is complete. Model development, with the assistance of the software provider, is currently in process. While we are currently unable to reasonably estimate the impact of adopting this ASU, we expect the impact of adoption will be influenced by the composition of our loan and securities portfolios as well as the economic conditions and forecasts at the time of adoption. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement: Disclosure Framework - Changes to the Disclosures Requirements for Fair Value Measurement . This ASU eliminates, modifies and adds certain disclosure requirements for fair value measurements. The ASU adds disclosure requirements for the changes in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The effective date of this ASU for the Company is October 1, 2020, with early adoption permitted. Entities are allowed to elect early adoption of the eliminated or modified disclosure requirements and delay adoption of the new disclosure requirements until their effective date. Since this ASU only requires disclosure changes, it will not have a significant impact on the Company's consolidated financial condition and results of operations. In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software: Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract . The ASU 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 (and hosting arrangements that include internal-use software license). The effective date of this ASU for the Company is October 1, 2020, with early adoption permitted. The Company is currently evaluating the effect of the ASU on the Company's consolidated financial condition, results of operations and disclosures. In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. This ASU makes clarifications and corrections to the application of the guidance contained in each of the amended topics. According to the provisions of the ASU, entities that have not adopted ASU 2017-12 prior to the issuance of ASU 2019-04 shall adopt the provisions of both ASUs at the same time. The effective date of the non-hedging amendments contained in ASU 2019-04 for the Company is October 1, 2020. The Company is currently evaluating the effect of the non-hedging amendments contained in this ASU on the Company's consolidated financial condition, results of operations and disclosures.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE Shares acquired by the ESOP are not included in basic average shares outstanding until the shares are committed for allocation or vested to an employee's individual account. Unvested shares awarded pursuant to the Company's restricted stock benefit plans are treated as participating securities in the computation of EPS pursuant to the two-class method as they contain nonforfeitable rights to dividends. The two-class method is an earnings allocation that determines EPS for each class of common stock and participating security.

In general, as market yields rise, the fair value of securities will decrease; as market yields fall, the fair value of securities will increase. Management generally views changes in fair value caused by changes in market yields as temporary. Therefore, these securities have not been classified as other-than-temporarily impaired. The impairment is also considered temporary because scheduled coupon payments have been made, it is anticipated that the entire principal balance will be collected as scheduled, and management neither intends to sell the securities, nor is it more likely than not that the Company will be required to sell the securities, before the recovery of the remaining amortized cost amount, which could be at maturity. As a result of the analysis, management has concluded that no other-than-temporary impairments existed at December 31, 2019 or September 30, 2019 . The amortized cost and estimated fair value of AFS debt securities as of December 31, 2019 , by contractual maturity, are shown below. Actual principal repayments may differ from contractual maturities due to prepayment or early call privileges by the issuer. In the case of MBS, borrowers on the underlying loans generally have the right to prepay their loans without prepayment penalty. For this reason, MBS are not included in the maturity categories.

The Bank also originates consumer loans primarily secured by one- to four-family residential properties and originates and participates in commercial loans. The Bank has a loan concentration in one- to four-family loans and a geographic concentration of these loans in Kansas and Missouri. One- to four-family loans - Full documentation to support an applicant's credit and income, and sufficient funds to cover all applicable fees and reserves at closing, are required on all loans. Generally, loans are underwritten according to the "ability to repay" and "qualified mortgage" standards, as issued by the Consumer Financial Protection Bureau ("CFPB"). Properties securing one- to four-family loans are appraised by either staff appraisers or fee appraisers, both of which are independent of the loan origination function. The underwriting standards for loans purchased from correspondent lenders are generally similar to the Bank's internal underwriting standards. The underwriting of loans purchased from correspondent lenders on a loan-by-loan basis is performed by the Bank's underwriters. The Bank also originates owner-occupied construction-to-permanent loans secured by one- to four-family residential real estate. Construction draw requests and the supporting documentation are reviewed and approved by designated personnel. The Bank also performs regular documented inspections of the construction project to ensure the funds are being used for the intended purpose and the project is being completed according to the plans and specifications provided. Commercial loans - The Bank's commercial real estate and commercial construction loans are originated by the Bank or are in participation with a lead bank. When underwriting a commercial real estate or commercial construction loan, several factors are considered, such as the income producing potential of the property, cash equity provided by the borrower, the financial strength of the borrower, managerial expertise of the borrower or tenant, feasibility studies, lending experience with the borrower and the marketability of the property. For commercial real estate and commercial construction participation loans, the Bank performs the same underwriting procedures as if the loan was being originated by the Bank. At the time of origination, loan-to-value ("LTV") ratios on commercial real estate loans generally do not exceed 85% of the appraised value of the property securing the loans and the minimum debt service coverage ratio is generally 1.15 . For commercial construction loans, LTV ratios generally do not exceed 80% of the projected appraised value of the property securing the loans and the minimum debt service coverage ratio is generally 1.15 , but it applies to the projected cash flows, and the borrower must have successful experience with the construction and operation of properties similar to the subject property. Appraisals on properties securing these loans are performed by independent state certified fee appraisers. The Bank's commercial and industrial loans are generally made in the Bank's market areas and are underwritten on the basis of the borrower's ability to service the debt from income. Working capital loans are primarily collateralized by short-term assets whereas term loans are primarily collateralized by long-term assets. In general, commercial and industrial loans involve more credit risk than commercial real estate loans due to the type of collateral securing these loans. As a result of these additional complexities, variables and risks, these loans require more thorough underwriting and servicing than other types of loans. Consumer loans - The Bank offers a variety of secured consumer loans, including home equity loans and lines of credit, home improvement loans, vehicle loans, and loans secured by deposits. The Bank also originates a very limited amount of unsecured loans. The majority of the consumer loan portfolio is comprised of home equity lines of credit for which the Bank also has the first mortgage or the home equity line of credit is in the first lien position. The underwriting standards for consumer loans include a determination of an applicant's payment history on other debts and an assessment of an applicant's ability to meet existing obligations and payments on the proposed loan. Although creditworthiness of an applicant is a primary consideration, the underwriting process also includes a comparison of the value of the security in relation to the proposed loan amount. Credit Quality Indicators - Based on the Bank's lending emphasis and underwriting standards, management has segmented the loan portfolio into three segments: (1) one- to four-family; (2) consumer; and (3) commercial. These segments are further divided into classes for purposes of providing disaggregated information about the credit quality of the loan portfolio. The classes are: one- to four-family - originated, one- to four-family - correspondent purchased, one- to four-family - bulk purchased, consumer - home equity, consumer - other, commercial - commercial real estate, and commercial - commercial and industrial. One- to four-family construction loans are included in either the originated class or correspondent purchased class, and commercial construction loans are included in the commercial real estate class. The Bank's primary credit quality indicators for the one- to four-family and consumer - home equity loan portfolios are delinquency status, asset classifications, LTV ratios, and borrower credit scores. The Bank's primary credit quality indicators for the commercial and consumer - other loan portfolios are delinquency status and asset classifications. The following tables present the recorded investment, by class, in loans 30 to 89 days delinquent, loans 90 or more days delinquent or in foreclosure, total delinquent loans, current loans, and total recorded investment at the dates presented. The recorded investment in loans is defined as the unpaid principal balance of a loan, less charge-offs and inclusive of unearned loan fees and deferred costs. At December 31, 2019 and September 30, 2019 , all loans 90 or more days delinquent were on nonaccrual status.

The carrying value of residential OREO held as a result of obtaining physical possession upon completion of a foreclosure or through completion of a deed in lieu of foreclosure was $512 thousand at December 31, 2019 and $745 thousand at September 30, 2019 . The following table presents the recorded investment, by class, in loans classified as nonaccrual at the dates presented.

Loan classifications are defined as follows: • Special mention - These loans are performing loans on which known information about the collateral pledged or the possible credit problems of the borrower(s) have caused management to have doubts as to the ability of the borrower(s) to comply with present loan repayment terms and which may result in the future inclusion of such loans in the non-performing loan categories. • Substandard - A loan is considered substandard if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Substandard loans include those characterized by the distinct possibility the Bank will sustain some loss if the deficiencies are not corrected. • Doubtful - Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses present make collection or liquidation in full on the basis of currently existing facts and conditions and values highly questionable and improbable. • Loss - Loans classified as loss are considered uncollectible and of such little value that their continuance as assets on the books is not warranted. The following table sets forth the recorded investment in loans classified as special mention or substandard, by class, at the dates presented. Special mention and substandard loans are included in the ACL formula analysis model if the loans are not individually evaluated for loss. Loans classified as doubtful or loss are individually evaluated for loss. At the dates presented, there were no loans classified as doubtful, and all loans classified as loss were fully charged-off.

Borrower credit scores are intended to provide an indication as to the likelihood that a borrower will repay their debts. Credit scores are updated at least semiannually, with the last update in September 2019, from a nationally recognized consumer rating agency. The LTV ratios provide an estimate of the extent to which the Bank may incur a loss on any given loan that may go into foreclosure. The consumer - home equity LTV does not take into account the first lien position, if applicable. The LTV ratios were based on the current loan balance and either the lesser of the purchase price or original appraisal, or the most recent Bank appraisal, if available. In most cases, the most recent appraisal was obtained at the time of origination.

Debt Disclosure [Abstract]
Borrowed Funds	BORROWED FUNDS FHLB Borrowings and Interest Rate Swaps - At December 31, 2019 and September 30, 2019 , the Bank had entered into interest rate swap agreements with a total notional amount of $640.0 million in order to hedge the variable cash flows associated with $640.0 million of adjustable-rate FHLB advances. At December 31, 2019 and September 30, 2019 , the interest rate swap agreements had an average remaining term to maturity of 4.2 years and 4.5 years , respectively. The interest rate swaps were designated as cash flow hedges and involve the receipt of variable amounts from a counterparty in exchange for the Bank making fixed-rate payments over the life of the interest rate swap agreements. At December 31, 2019 and September 30, 2019 , the interest rate swaps were in a loss position with a total fair value of $25.9 million and $33.1 million , respectively, which was reported in accounts payable and accrued expenses on the consolidated balance sheet. During the three months ended December 31, 2019 and December 31, 2018 , $709 thousand and $151 thousand , respectively, was reclassified from AOCI as an increase to interest expense. There was no hedge ineffectiveness recognized in the consolidated statements of income during either period. At December 31, 2019 , the Company estimated that $5.9 million of interest expense associated with the interest rate swaps will be reclassified from AOCI as an increase to interest expense on FHLB borrowings during the next 12 months. The Bank has minimum collateral posting thresholds with its derivative counterparties and posts collateral on a daily basis. The Bank posted cash collateral of $26.6 million at December 31, 2019 and $33.3 million at September 30, 2019 .

Fair Value Of Financial Instrum

Fair Value Of Financial Instruments	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Of Financial Instruments	FAIR VALUE OF FINANCIAL INSTRUMENTS Fair Value Measurements - The Company uses fair value measurements to record fair value adjustments to certain financial instruments and to determine fair value disclosures in accordance with Accounting Standards Codification ("ASC") 820 and ASC 825. The Company's AFS securities and interest rate swaps are recorded at fair value on a recurring basis. Additionally, from time to time, the Company may be required to record at fair value other financial instruments on a non-recurring basis, such as OREO and loans individually evaluated for impairment. These non-recurring fair value adjustments involve the application of lower of cost or fair value accounting or write-downs of individual financial instruments. The Company groups its financial instruments at fair value in three levels based on the markets in which the financial instruments are traded and the reliability of the assumptions used to determine fair value. These levels are: • Level 1 - Valuation is based upon quoted prices for identical instruments traded in active markets. • Level 2 - Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market. • Level 3 - Valuation is generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect the Company's own estimates of assumptions that market participants would use in pricing the financial instrument. Valuation techniques include the use of option pricing models, discounted cash flow models, and similar techniques. The results cannot be determined with precision and may not be realized in an actual sale or immediate settlement of the financial instrument. The Company bases its fair values on the price that would be received from the sale of a financial instrument in an orderly transaction between market participants at the measurement date under current market conditions. The Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. The following is a description of valuation methodologies used for financial instruments measured at fair value on a recurring basis. AFS Securities - The Company's AFS securities portfolio is carried at estimated fair value. The majority of the securities within the AFS portfolio were issued by GSEs. The Company primarily uses prices obtained from third party pricing services to determine the fair value of its securities. On a quarterly basis, management corroborates a sample of prices obtained from the third party pricing service for Level 2 securities by comparing them to an independent source. If the price provided by the independent source varies by more than a predetermined percentage from the price received from the third party pricing service, then the variance is researched by management. The Company did not have to adjust prices obtained from the third party pricing service when determining the fair value of its securities during the three months ended December 31, 2019 or during fiscal year 2019. The Company's major security types, based on the nature and risks of the securities, are: • GSE Debentures - Estimated fair values are based on a discounted cash flow method. Cash flows are determined by taking any embedded options into consideration and are discounted using current market yields for similar securities. (Level 2) • MBS - Estimated fair values are based on a discounted cash flow method. Cash flows are determined based on prepayment projections of the underlying mortgages and are discounted using current market yields for benchmark securities. (Level 2) • Municipal Bonds - Estimated fair values are based on a discounted cash flow method. Cash flows are determined by taking any embedded options into consideration and are discounted using current market yields for securities with similar credit profiles. (Level 2) Interest Rate Swaps - The Company's interest rate swaps are designated as cash flow hedges and are reported at fair value in other assets on the consolidated balance sheet if in a gain position, and in accounts payable and accrued expenses if in a loss position, with any unrealized gains and losses, net of taxes, reported as AOCI in stockholders' equity. See "Note 5. Borrowed Funds" for additional information. The estimated fair values of the interest rates swaps are obtained from the counterparty and are determined by a discounted cash flow analysis using observable market-based inputs. On a quarterly basis, management corroborates the estimated fair values by internally calculating the estimated fair value using a discounted cash flow analysis with independent observable market-based inputs from a third party. No changes were made to the estimated fair values during the three months ended December 31, 2019 or during fiscal year 2019. (Level 2) The following tables provide the level of valuation assumption used to determine the carrying value of the Company's financial instruments measured at fair value on a recurring basis at the dates presented. The Company did not have any Level 3 financial instruments measured at fair value on a recurring basis at December 31, 2019 or September 30, 2019 .

Loans Receivable - The fair value of loans individually evaluated for impairment on a non-recurring basis during the three months ended December 31, 2019 and 2018 that were still held in the portfolio as of December 31, 2019 and 2018 was $3.9 million and $1.8 million , respectively. The one- to four-family loans included in this amount were individually evaluated to determine if the carrying value of the loan was in excess of the fair value of the collateral, less estimated selling costs of 10% . Fair values were estimated through current appraisals. Management does not adjust or apply a discount to the appraised value of one- to four-family loans, except for the estimated sales cost noted above, and the primary unobservable input for these loans was the appraisal. For commercial loans, if the most recent appraisal or book value of the collateral does not reflect the current market conditions due to the passage of time and/or other factors, management will make adjustments to the existing appraised or book value based on knowledge of local market conditions, recent transactions, and estimated selling costs, if applicable. Adjustments to appraised or book values are generally based on assumptions not observable in the marketplace. The primary significant unobservable inputs for commercial loans individually evaluated for impairment during the three months ended December 31, 2019 were downward adjustments to the book value of the collateral for lack of marketability. The adjustments ranged from 10% to 50% , with a weighted average of 18% . There were no commercial loans individually evaluated during the three months ended December 31, 2018 . Fair values of loans individually evaluated for impairment cannot be determined with precision and may not be realized in an actual sale or immediate settlement of the loan and, as such, are classified as Level 3. OREO - OREO primarily represents real estate acquired as a result of foreclosure or by deed in lieu of foreclosure and is carried at lower of cost or fair value. The fair value for OREO is estimated through current appraisals or listing prices, less estimated selling costs of 10% . Management does not adjust or apply a discount to the appraised value or listing price, except for the estimated sales costs noted above. The primary significant unobservable input for OREO was the appraisal or listing price. Fair values of foreclosed property cannot be determined with precision and may not be realized in an actual sale of the property and, as such, are classified as Level 3. The fair value of OREO measured on a non-recurring basis during the three months ended December 31, 2019 and 2018 that was still held in the portfolio as of December 31, 2019 and 2018 was $193 thousand and $192 thousand , respectively. The carrying value of the properties equaled the fair value of the properties at December 31, 2019 and 2018 . Fair Value Disclosures - The Company determined estimated fair value amounts using available market information and a variety of valuation methodologies as of the dates presented. Considerable judgment is required to interpret market data to develop the estimates of fair value. The estimates presented are not necessarily indicative of amounts the Company would realize from a current market exchange at subsequent dates.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	REVENUE RECOGNITION Details of the Company's primary types of non-interest income revenue streams by financial statement line item reported in the consolidated statements of income that are within the scope of ASC Topic 606 are below. During the three months ended December 31, 2019 and 2018 , revenue from contracts with customers totaled $4.0 million and $4.3 million , respectively. Deposit Service Fees Interchange Transaction Fees - Interchange transaction fee income primarily consists of interchange fees earned on a transactional basis through card payment networks. The performance obligation for these types of transactions is satisfied as services are rendered for each transaction and revenue is recognized daily concurrently with the transaction processing services provided to the cardholder. In order to participate in the card payment networks, the Company must pay various transaction related costs established by the networks ("interchange network charges"), including membership fees and a per unit charge for each transaction. The Company is acting as an agent for its debit card customers when they are utilizing the card payment networks; therefore, interchange transaction fee income is reported net of interchange network charges. Interchange network charges totaled $832 thousand and $944 thousand for the three months ended December 31, 2019 and 2018 , respectively. Service Charges on Deposit Accounts - Service charges on deposit accounts consist of account maintenance and transaction-based fees such as overdrafts, insufficient funds, wire transfers and the use of out-of-network ATMs. The Company's performance obligation is satisfied over a period of time, generally a month, for account maintenance and at the time of service for transaction-based fees. Revenue is recognized after the performance obligation is satisfied. Payments are typically collected from the customer's deposit account at the time the transaction is processed and/or at the end of the customer's statement cycle (typically monthly). Insurance Commissions Commissions are received on insurance product sales. The Company acts in the capacity of an agent between the Company's customer and the insurance carrier. The Company's performance obligation is satisfied when the terms of the policy have been agreed upon and the insurance policy becomes effective. Additionally, the Company earns performance-based incentives ("contingent insurance commissions") based on certain criteria established by the insurance carriers. Other Non-Interest Income Trust Asset Management Income - The Company provides trust asset management services to customers. The Company primarily earns fees for these services over time as the monthly services are provided and the Company assesses revenue at each month end. Fees are charged based on a tiered scale of the market value of the individual trust asset accounts at the end of the month.

Summary Of Significant Accoun_2

Summary Of Significant Accounting Policies (Policies)	3 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Basis of Presentation	The consolidated financial statements include the accounts of Capitol Federal Financial, Inc.® (the "Company") and its wholly-owned subsidiary, Capitol Federal Savings Bank (the "Bank"). The Bank has two wholly-owned subsidiaries, Capitol Funds, Inc. and Capital City Investments, Inc. Capitol Funds, Inc. has a wholly-owned subsidiary, Capitol Federal Mortgage Reinsurance Company. Capital City Investments, Inc. is a real estate and investment holding company. All intercompany accounts and transactions have been eliminated in consolidation. The consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation have been included. These statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended September 30, 2019 , filed with the Securities and Exchange Commission ("SEC"). Interim results are not necessarily indicative of results for a full year.
Cash, Cash Equivalents, Restricted Cash and Restricted Cash Equivalents	Cash, cash equivalents, restricted cash and restricted cash equivalents reported in the statement of cash flows include cash and cash equivalents of $70.7 million and $220.4 million at December 31, 2019 and September 30, 2019 , respectively, and restricted cash and cash equivalents of $26.6 million and $33.3 million at December 31, 2019 at September 30, 2019 , respectively, which was included in other assets on the consolidated balance sheet. The restricted cash and cash equivalents relate to the collateral postings to/from the Bank's derivative counterparties associated with the Bank's interest rate swaps. See additional discussion regarding the interest rate swaps in Note 5. Borrowed Funds.
Net Presentation of Cash Flows Related to Borrowings	At times, the Bank enters into certain FHLB advances with contractual maturities of 90 days or less. Cash flows related to these advances are reported on a net basis in the consolidated statements of cash flows. There was no FHLB advance activity reported on a net basis in the consolidated statements of cash flows during the three months ended December 31, 2019 and 2018 .
Leases	The Company leases real estate property for branches, ATMs, and certain equipment. All of the leases in which the Company is the lessee are classified as operating leases. The Company determines if an arrangement is a lease at inception and if the lease is an operating lease or a finance lease. Operating lease right-of-use assets represent the Company's right to use an underlying asset during the lease term and operating lease liabilities represent the Company's obligation to make lease payments arising from the lease. The right-of-use assets associated with operating leases are recorded in other assets in the Company's consolidated balance sheets. The lease liabilities associated with operating leases are included in accounts payable and accrued expenses on the consolidated balance sheets. The period over which the right-of-use asset is amortized is generally the lesser of the expected remaining term or the remaining useful life of the leased asset. The lease liability is decreased as periodic lease payments are made. The Company performs impairment assessments for right-of-use assets when events or changes in circumstances indicate that their carrying values may not be recoverable. The calculated amount of the right-of-use assets and lease liabilities are impacted by the length of the lease term and the discount rate used to calculate the present value of the minimum remaining lease payments. The Company's lease agreements often include one or more options to renew at the Company's discretion. If, at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company includes the extended term in the calculation of the right-of-use asset and lease liability. Generally, the Company cannot practically determine the interest rate implicit in the lease so the Company's incremental borrowing rate is used as the discount rate for the lease. The Company uses FHLB advance interest rates, which have been deemed as the Company's incremental borrowing rate, at lease inception based upon the term of the lease. For operating leases existing prior to October 1, 2019, the rate for the remaining lease term as of October 1, 2019 was applied. The Company's lease agreements do not contain any material residual value guarantees or material restrictive covenants. Lease expense, variable lease expense and short-term lease expense are included in occupancy expense in the Company's consolidated statements of income. For facility-related leases, the Company elected, by lease class, to not separate lease and non-lease components. Lease expense is recognized on a straight-line basis over the lease term. Variable lease expense primarily represents payments such as common area maintenance and utilities and are recognized as expense in the period when those payments are incurred. Short-term lease expense relates to leases with an initial term of 12 months or less. The Company has elected to not record a right-of-use asset or lease liability for short-term leases.
Recent Accounting Pronouncements	In February 2016, the Financial Accounting Standards Board ("FASB") issued ASU 2016-02, Leases . The ASU, as amended, revises lease accounting guidance by requiring that lessees recognize the assets and liabilities arising from leases on the balance sheet. Additionally, the ASU requires entities to disclose both quantitative and qualitative information regarding their leasing activities. The accounting applied by a lessor is largely unchanged from that applied under the previous guidance. In July 2018, the FASB issued ASU 2018-11, Leases , which provides entities with relief from the costs of implementation by allowing the option to not restate comparative periods as part of the transition. The ASU, as amended, became effective for the Company on October 1, 2019. Upon adoption, the Company elected the modified retrospective approach and the optional transition method under which the Company used the effective date as the date of initial application of the amendments. The optional practical expedients the Company elected include: (1) not reassessing whether any expired or existing contracts are or contain leases, (2) not reassessing the classification of any expired or existing contracts, (3) not reassessing initial direct costs for existing leases, and (4) using hindsight for leases existing at adoption date. For leases with an initial term of 12 months or less, the Company elected the short-term lease option, which entails not recognizing right-of-use assets and lease liabilities for these leases. Additionally, the Company elected, for facility-related leases, the practical expedient that allows an entity to elect, by lease class, the ability to not separate lease and non-lease components. Upon adoption, the Company recognized a right-of-use asset of $15.7 million and a lease liability of $15.5 million , related to the Company's non-cancellable operating lease commitments based on the present value of the expected remaining lease payments as of October 1, 2019. The cumulative-effect adjustment to retained earnings at the time of adoption totaled $88 thousand . These ASUs did not have a material impact on the Company's results of operations and cash flows at the time of adoption. The disclosures required by the ASU are included in Note 9. Leases. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments . The ASU, as amended, replaces the incurred loss impairment methodology in current GAAP, which requires credit losses to be recognized when it is probable that a loss has been incurred, with a new impairment methodology. The new impairment methodology requires an entity to measure, at each reporting date, the expected credit losses of financial assets not measured at fair value, such as loans and loan commitments, over their contractual lives. Under the new impairment methodology, expected credit losses will be measured at each reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Additionally, the ASU amends the current credit loss measurements for AFS debt securities. Credit losses related to AFS debt securities will be recorded through the ACL rather than as a direct write-down as per current GAAP. The ASU also requires enhanced disclosures related to credit quality and significant estimates and judgments used by management when estimating credit losses. The ASU will become effective for the Company on October 1, 2020. The Company continues to work with a software provider on the application and implementation of the new accounting guidance. The integration of the Company's data with the software provider is complete. Model development, with the assistance of the software provider, is currently in process. While we are currently unable to reasonably estimate the impact of adopting this ASU, we expect the impact of adoption will be influenced by the composition of our loan and securities portfolios as well as the economic conditions and forecasts at the time of adoption. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement: Disclosure Framework - Changes to the Disclosures Requirements for Fair Value Measurement . This ASU eliminates, modifies and adds certain disclosure requirements for fair value measurements. The ASU adds disclosure requirements for the changes in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements and the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The effective date of this ASU for the Company is October 1, 2020, with early adoption permitted. Entities are allowed to elect early adoption of the eliminated or modified disclosure requirements and delay adoption of the new disclosure requirements until their effective date. Since this ASU only requires disclosure changes, it will not have a significant impact on the Company's consolidated financial condition and results of operations. In August 2018, the FASB issued ASU 2018-15, Intangibles - Goodwill and Other - Internal-Use Software: Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract . The ASU 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 (and hosting arrangements that include internal-use software license). The effective date of this ASU for the Company is October 1, 2020, with early adoption permitted. The Company is currently evaluating the effect of the ASU on the Company's consolidated financial condition, results of operations and disclosures. In April 2019, the FASB issued ASU 2019-04, Codification Improvements to Topic 326, Financial Instruments-Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments. This ASU makes clarifications and corrections to the application of the guidance contained in each of the amended topics. According to the provisions of the ASU, entities that have not adopted ASU 2017-12 prior to the issuance of ASU 2019-04 shall adopt the provisions of both ASUs at the same time. The effective date of the non-hedging amendments contained in ASU 2019-04 for the Company is October 1, 2020. The Company is currently evaluating the effect of the non-hedging amendments contained in this ASU on the Company's consolidated financial condition, results of operations and disclosures.

Weighted Average Loan-to-Value and Credit Score Information	The following table shows the weighted average credit score and weighted average LTV for one- to four-family loans and consumer home equity loans at the dates presented. Borrower credit scores are intended to provide an indication as to the likelihood that a borrower will repay their debts. Credit scores are updated at least semiannually, with the last update in September 2019, from a nationally recognized consumer rating agency. The LTV ratios provide an estimate of the extent to which the Bank may incur a loss on any given loan that may go into foreclosure. The consumer - home equity LTV does not take into account the first lien position, if applicable. The LTV ratios were based on the current loan balance and either the lesser of the purchase price or original appraisal, or the most recent Bank appraisal, if available. In most cases, the most recent appraisal was obtained at the time of origination.
