Organization, Consolidation and Presentation of Financial Statements [Abstract]
Presentation of Interim Information	1. Presentation of Interim Information First Savings Financial Group, Inc. (the “Company”) is a financial holding company and the parent of First Savings Bank (the “Bank”) and First Savings Insurance Risk Management, Inc. (the “Captive”). The Bank, which is a wholly-owned Indiana-chartered commercial bank subsidiary of the Company, provides a variety of banking services to individuals and business customers through fourteen locations in southern Indiana. The Bank attracts deposits primarily from the general public and uses those funds, along with other borrowings, primarily to originate commercial mortgage, residential mortgage, construction, commercial business and consumer loans, and to a lesser extent, to invest in mortgage-backed securities and other securities. The Bank has two wholly-owned subsidiaries: First Savings Investments, Inc., a Nevada corporation that manages a securities portfolio, and Southern Indiana Financial Corporation, which is currently inactive. At September 30, 2016, the Bank had a third wholly-owned subsidiary, FFCC, Inc. (“FFCC”), which was an Indiana corporation that participated in commercial real estate development and leasing. In accordance with the Plan of Complete Liquidation adopted by FFCC’s board of directors and approval by the Bank as its sole shareholder on December 21, 2016, FFCC voluntarily dissolved and completely liquidated effective December 31, 2016. As a result of the liquidation, FFCC distributed its net assets to the Bank on December 31, 2016. On April 25, 2017, the Bank formed Q2 Business Capital, LLC (“Q2”), which is an Indiana limited liability company that specializes in the origination and servicing of U.S. Small Business Administration (“SBA”) loans. The Bank owns 51 The Captive, which is a wholly-owned insurance subsidiary of the Company, is a Nevada corporation that provides property and casualty insurance to the Company, the Bank and the Bank’s active subsidiaries. In addition, the Captive provides reinsurance to eight other third-party insurance captives for which insurance may not be currently available or economically feasible in the insurance marketplace. In the opinion of management, the accompanying unaudited consolidated financial statements include all adjustments considered necessary to present fairly the financial position as of March 31, 2017, the results of operations for the three- and six-month periods ended March 31, 2017 and 2016, and the cash flows for the six-month periods ended March 31, 2017 and 2016. All of these adjustments are of a normal, recurring nature. Such adjustments are the only adjustments included in the unaudited consolidated financial statements. Interim results are not necessarily indicative of results for a full year. The unaudited consolidated financial statements and notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial statements, conform to general practices within the banking industry and are presented as permitted by the instructions to Form 10-Q. Accordingly, they do not contain certain information included in the Company’s audited consolidated financial statements and related notes for the year ended September 30, 2016 included in the Company’s Annual Report on Form 10-K. The unaudited consolidated financial statements include the accounts of the Company and its subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation. Certain prior period amounts have been reclassified to conform with the current period presentation. The reclassifications had no effect on net income or stockholders’ equity.

Investments, Debt and Equity Securities [Abstract]
Investment Securities	2. Investment Securities Agency bonds and notes, agency mortgage-backed securities and agency collateralized mortgage obligations (“CMO”) include securities issued by the Government National Mortgage Association (“GNMA”), a U.S. government agency, and the Federal National Mortgage Association (“FNMA”), the Federal Home Loan Mortgage Corporation (“FHLMC”) and the Federal Home Loan Bank (“FHLB”), which are U.S. government sponsored enterprises. The Company holds municipal bonds issued by municipal governments within the U.S. The Company also holds a pass through asset backed security guaranteed by the SBA representing participating interests in pools of long term debentures issued by state and local development companies certified by the SBA. Privately issued CMO and asset-backed securities (“ABS”) are complex securities issued by non government special purpose entities that are collateralized by residential mortgage loans and residential home equity loans. Investment securities have been classified according to management’s intent. Trading Account Securities The Company invests in small and medium lot, investment grade municipal bonds through a managed brokerage account. The brokerage account is managed by an investment advisory firm registered with the U.S. Securities and Exchange Commission.

Management evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market conditions warrant such evaluation. Consideration is given to (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. The total available for sale debt securities in loss positions at March 31, 2017, which consisted of U.S. government agency mortgage backed securities, agency CMOs and municipal bonds, had a fair value as a percentage of amortized cost of 98.03 The Company evaluates the existence of a potential credit loss component related to the decline in fair value of the privately issued CMO and ABS portfolios each quarter using an independent third party analysis. At March 31, 2017, the Company held fifteen privately-issued CMO and ABS securities acquired, in a 2009 bank merger, with an aggregate carrying value of $ 1.9 2.5 At March 31, 2017, there were no privately issued CMO or ABS in loss positions. Based on the independent third party analysis of the expected cash flows, management has determined that no other-than-temporary impairment is required to be recognized on the privately issued CMO and ABS portfolios. While the Company did not recognize a credit related impairment loss at March 31, 2017, additional deterioration in market and economic conditions may have an adverse impact on the credit quality in the future and therefore, require a credit related impairment charge. The unrealized losses on U.S. government agency mortgage-backed securities and CMOs and municipal bonds relate principally to current interest rates for similar types of securities. In analyzing an issuer’s financial condition, management considers whether the securities are issued by the federal government, its agencies, or other governments, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuer’s financial condition. As management has the ability to hold debt securities to maturity, or for the foreseeable future if classified as available for sale, no declines are deemed to be other-than-temporary. During the three and six month periods ended March 31, 2017 and 2016, the Company did not realize any gross gains or losses on sales of available for sale securities. Certain available for sale debt securities were pledged under repurchase agreements and to secure FHLB borrowings at March 31, 2017 and September 30, 2016, and may be pledged to secure federal funds borrowings.

The Company classifies loans based on credit risk at least quarterly. The Company uses the following regulatory definitions for risk ratings: Special Mention: Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the Company’s credit position at some future date. Substandard: Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company 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 make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loss: Loans classified as loss are considered uncollectible and of such little value that their continuance on the Company’s books as an asset is not warranted.

By granting the concession, the Company expects to obtain more cash or other value from the debtor, or to increase the probability of receipt, than would be expected by not granting the concession. The concession may include, but is not limited to, reduction of the stated interest rate of the loan, reduction of accrued interest, extension of the maturity date or reduction of the face amount or maturity amount of the debt. A concession will be granted when, as a result of the restructuring, the Company does not expect to collect all amounts due, including interest at the original stated rate. A concession may also be granted if the debtor is not able to access funds elsewhere at a market rate for debt with similar risk characteristics as the restructured debt. The Company’s determination of whether a loan modification is a TDR considers the individual facts and circumstances surrounding each modification. Loans modified in a TDR may be retained on accrual status if the borrower has maintained a period of performance in which the borrower’s lending relationship was not greater than ninety days delinquent at the time of restructuring and the Company determines the future collection of principal and interest is reasonably assured. Loans modified in a TDR that are placed on nonaccrual status at the time of restructuring will continue on nonaccrual status until the Company determines the future collection of principal and interest is reasonably assured, which generally requires that the borrower demonstrate a period of performance according to the restructured terms of at least six consecutive months. Accruing Nonaccrual Total (In thousands) March 31, 2017: Residential real estate $ 2,720 $ - $ 2,720 Commercial real estate 4,497 1,383 5,880 Land and land development 32 - 32 Commercial business 89 112 201 Consumer 102 - 102 Total $ 7,440 $ 1,495 $ 8,935 September 30, 2016: Residential real estate $ 2,590 $ - $ 2,590 Commercial real estate 4,692 1,512 6,204 Commercial business 95 120 215 Consumer 109 - 109 Total $ 7,486 $ 1,632 $ 9,118 Pre- Post- Modification Modification Number of Principal Principal Loans Balance Balance (In thousands) Three Months Ended March 31, 2017: Residential real estate 1 $ 452 $ 453 Land and land development 1 31 32 Total 2 $ 483 $ 485 Six Months Ended March 31, 2017: Residential real estate 1 $ 452 $ 453 Land and land development 1 31 32 Total 2 $ 483 $ 485 Three Months Ended March 31, 2016: Residential real estate 1 $ 107 $ 121 Total 1 $ 107 $ 121 Six Months Ended March 31, 2016: Residential real estate 5 $ 181 $ 247 Commercial business 2 88 118 Total 7 $ 269 $ 365 For the TDRs listed above, the terms of modification included deferral of contractual principal and interest payments, reduction of the stated interest rate and extension of the maturity date where the debtor was unable to access funds elsewhere at a market interest rate for debt with similar risk characteristics. At March 31, 2017 and September 30, 2016, the Company had not committed to lend any additional amounts to customers with outstanding loans classified as TDRs. There were no principal charge-offs recorded as a result of TDRs during the three and six month periods ended March 31, 2017 and 2016. There was no specific allowance for loan losses related to TDRs modified during the three and six month periods ended March 31, 2017 and 2016. In the event that a TDR subsequently defaults, the Company evaluates the restructuring for possible impairment. As a result, the related allowance for loan losses may be increased or charge-offs may be taken to reduce the carrying amount of the loan. During the three and six month periods ended March 31, 2017 and 2016, the Company did not have any TDRs that were modified within the previous twelve months and for which there was a payment default. Loan Servicing Rights The Company originates loans to commercial customers under the SBA 7(a) and other programs. During the fiscal year ended September 30, 2016, the Company began selling the guaranteed portion of the SBA loans with servicing retained. Loan servicing rights on originated SBA loans that have been sold are initially recorded at fair value. Capitalized servicing rights are then amortized in proportion to and over the period of estimated net servicing income. Impairment of servicing rights is assessed using the present value of estimated future cash flows. The aggregate fair value of loan servicing rights approximates its carrying value. A valuation model employed by an independent third party calculates the present value of future cash flows and is used to estimate fair value at the date of sale and on a quarterly basis for impairment analysis purposes. Management periodically compares the valuation model inputs and results to published industry data in order to validate the model results and assumptions. Key assumptions used to estimate the fair value of the loan servicing rights include the discount rate and prepayment speed assumptions. For purposes of impairment, risk characteristics such as interest rate, loan type, term and investor type are used to stratify the loan servicing rights. Impairment is recognized through a valuation allowance to the extent that fair value is less than the carrying amount. Changes in the valuation allowance are reported in net gain on sales of loans in the consolidated statements of income. The unpaid principal balance of SBA loans serviced for others was $ 33.9 13.6 5.9 43,000 15,000 27,000 54,000 69,000 20,000 35,000 Three Months Ended Six Months Ended March 31, March 31, 2017 2016 2017 2016 (In thousands) Balance, beginning of period $ 558 $ 156 $ 310 $ - Servicing rights resulting from transfers of loans 247 - 507 156 Amortization (22) - (34) - Change in valuation allowance - - - - Balance, end of period $ 783 $ 156 $ 783 $ 156 Residential mortgage loans originated for sale in the secondary market continue to be sold with servicing released.

Earnings Per Share [Abstract]
Supplemental Disclosure for Earnings Per Share	6. Supplemental Disclosure for Earnings Per Share When presented, basic earnings per share are computed by dividing income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflect the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the earnings of the entity.

Fair Value Measurements and Disclosures about Fair Value of Financial Instruments	8. Fair Value Measurements and Disclosures about Fair Value of Financial Instruments Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 820 , Fair Value Measurements, Level 1: Inputs to the valuation methodology are quoted prices, unadjusted, for identical assets or liabilities in active markets. A quoted market price in an active market provides the most reliable evidence of fair value and shall be used to measure fair value whenever available. Level 2: Inputs to the valuation methodology include quoted market prices for similar assets or liabilities in active markets; quoted market prices for identical or similar assets or liabilities in markets that are not active; or inputs that are derived principally from or can be corroborated by observable market data by correlation or other means. Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement. Level 3 assets and liabilities include financial instruments whose value is determined using discounted cash flow methodologies, as well as instruments for which the determination of fair value requires significant management judgment or estimation. A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to all of the Company’s financial assets carried at fair value or the lower of cost or fair value.

If quoted market prices are not available, fair value is based on internally developed models or obtained from third parties that primarily use, as inputs, observable market-based parameters or a matrix pricing model that employs the Bond Market Association’s standard calculations for cash flow and price/yield analysis and observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value, or at the lower of cost or fair value. These adjustments may include unobservable parameters. Any such valuation adjustments have been applied consistently over time. The Company’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. There have been no changes in the valuation techniques and related inputs used for assets measured at fair value on a recurring and nonrecurring basis during the six-month period ended March 31, 2017. Trading Account Securities and Securities Available for Sale. Securities classified as trading and available for sale are reported at fair value on a recurring basis. These securities are classified as Level 1 of the valuation hierarchy where quoted market prices from reputable third-party brokers are available in an active market. If quoted market prices are not available, the Company obtains fair value measurements from an independent pricing service. These securities are reported using Level 2 inputs and the fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, U.S. government and agency yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and the security’s terms and conditions, among other factors. For securities where quoted market prices, market prices of similar securities or prices from an independent third party pricing service are not available, fair values are calculated using discounted cash flows or other market indicators and are classified within Level 3 of the fair value hierarchy. Changes in fair value of trading account securities are reported in noninterest income. Changes in fair value of securities available for sale are recorded in other comprehensive income, net of income tax effect. Impaired Loans . Impaired loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly. The fair value of impaired loans is classified as Level 3 in the fair value hierarchy. Impaired loans are measured at the present value of estimated future cash flows using the loan's effective interest rate or the fair value of the collateral if the loan is a collateral-dependent loan. Collateral may be real estate and/or business assets, including equipment, inventory and/or accounts receivable, and its fair value is generally determined based on real estate appraisals or other independent evaluations by qualified professionals. The appraisals are generally then discounted by management in order to reflect management’s estimate of the fair value of the collateral given the current market conditions and the condition of the collateral. At March 31, 2017 and September 30, 2016, the significant unobservable inputs used in the fair value measurement of impaired loans included a discount from appraised value ranging from 0.0 15.0 0.0 6.0 42,000 Loans Held for Sale . Loans held for sale are carried at the lower of cost or market value. The portfolio is comprised of residential mortgage loans and SBA loans. The fair value of loans held for sale is based on specific prices of the underlying contracts for sale to investors, and is classified as Level 2 in the fair value hierarchy. Loan Servicing Rights . Loan servicing rights represent the value associated with servicing SBA loans that have been sold. The fair value of loan servicing rights is determined on a quarterly basis by an independent third party valuation model using market-based discount rate and prepayment assumptions, and is classified as Level 3 in the fair value hierarchy. At March 31, 2017, the significant unobservable inputs used in the fair value measurement of loan servicing rights included discount rates ranging from 9.01 13.59 11.84 3.62 8.84 6.88 8.54 14.46 12.27 4.25 8.71 6.75 Other Real Estate Owned . Other real estate owned held for sale is reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly. The fair value of other real estate owned is classified as Level 3 in the fair value hierarchy. Other real estate owned is reported at fair value less estimated costs to dispose of the property. The fair values are determined by real estate appraisals, which are then generally discounted by management in order to reflect management’s estimate of the fair value of the property given current market conditions and the condition of the property. At March 31, 2017, the significant unobservable inputs used in the fair value measurement of other real estate owned included a discount from appraised value (including estimated costs to sell the property) ranging from 15.0 57.6 31.1 15.0 34.2 24.6 10,000 20,000 79,000 Transfers Between Categories . There were no transfers into or out of Level 3 financial assets for the three and six month periods ended March 31, 2017 and 2016. GAAP requires disclosure of fair value information about financial instruments for interim reporting periods, whether or not recognized in the consolidated balance sheet. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instruments. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Company.

The fair value of financial instruments with off-balance-sheet risk is not material. The following methods and assumptions were used to estimate the fair value of each class of financial instrument for which it is practicable to estimate that value: Cash and Cash Equivalents For cash and short-term instruments, including cash and due from banks and interest-bearing deposits with banks, the carrying amount is a reasonable estimate of fair value. Investment Securities and Interest-Bearing Time Deposits For debt securities and interest-bearing time deposits, the Company obtains fair value measurements from an independent pricing service and the fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, U.S. government and agency yield curves, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and the security’s terms and conditions, among other factors. For FRB and FHLB stock, which are restricted equity securities, the carrying amount is a reasonable estimate of fair value because they are not marketable. Loans The fair value of loans, excluding loans held for sale, is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and terms. Impaired loans are valued at the lower of their carrying value or fair value, as previously described. The carrying amount of accrued interest receivable approximates its fair value. The fair value of loans held for sale is estimated based on specific prices of underlying contracts for sales to investors, as previously described. Other Assets For equity method investments, such as the Company’s investment in the historic tax credit entity, where a quoted market value is not available, the carrying amount is a reasonable estimate of fair value. However, subsequent to the recognition of the historic tax credits (as discussed in Note 4), management has determined that its investment in the historic tax credit entity has no residual value and therefore has recorded an impairment loss for the amount of the investment as of March 31, 2017 and September 30, 2016. The fair value of loan serving rights is determined by a valuation model employed by an independent third party using market-based discount rate and prepayment assumptions, as previously described. Deposits The fair value of demand and savings deposits and other transaction accounts is the amount payable on demand at the balance sheet date. The fair value of fixed-maturity time deposits is estimated by discounting the future cash flows using the rates currently offered for deposits with similar remaining maturities. The carrying amount of accrued interest payable approximates its fair value. Borrowed Funds Borrowed funds include borrowings from the FHLB and repurchase agreements. Fair value for FHLB advances and long-term repurchase agreements is estimated by discounting the future cash flows at current interest rates for FHLB advances of similar maturities. For short-term repurchase agreements and FHLB line of credit borrowings, the carrying value is a reasonable estimate of fair value.

Stock Based Compensation Plans The Company maintains two equity incentive plans under which stock options and restricted stock have or can be granted, the 2010 Equity Incentive Plan (“2010 Plan”) approved by the Company’s shareholders in February 2010 and the 2016 Equity Incentive Plan (“2016 Plan”) approved by the Company’s shareholders in February 2016. At March 31, 2017, all available awards had been granted under the 2010 Plan. The aggregate number of shares of the Company’s common stock available for issuance under the 2016 Plan may not exceed 88,000 66,000 22,000 19,440 14,705 4,735 Stock Options Under the plans, the Company may grant both non-statutory and incentive stock options that may not have a term exceeding ten years. In the case of incentive stock options, the aggregate fair value (determined at the time the incentive stock options are granted) which are first exercisable during any calendar year shall not exceed $ 100,000 Stock options granted generally vest ratably over five years and are exercisable in whole or in part for a period up to ten years from the date of the grant. Compensation expense is measured based on the fair market value of the options at the grant date and is recognized ratably over the period during which the shares are earned (the vesting period). The fair market value of stock options granted is estimated at the date of grant using a binomial option pricing model. Expected volatilities are based on historical volatility of the Company’s stock. The expected term of options granted represents the period of time that options are expected to be outstanding. The risk free rate for the expected life of the options is based on the U.S. Treasury yield curve in effect at the grant date.

Regulatory Capital

Banking and Thrift [Abstract]
Regulatory Capital	12. Regulatory Capital The Company and Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and Bank must meet specific capital guidelines that involve quantitative measures of the Company’s and Bank’s assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The Company’s and Bank’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company and Bank to maintain minimum amounts and ratios (set forth in the table below) of total, Tier 1 and common equity Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and Tier 1 capital (as defined) to average assets (as defined). The final rules implementing the Basel Committee on Banking Supervision’s capital guidelines for U.S. banks (“Basel III rules”) became effective for the Company and the Bank on January 1, 2015, with full compliance with all of the requirements being phased in over a multi-year schedule through 2019. Under the Basel III rules, the Bank must hold a conservation buffer above the adequately capitalized risk-based capital ratios disclosed in the table below. The capital conservation buffer is being phased in from 0.0% for 2015 to 2.5% by 2019. The capital conservation buffer is 1.25% for 2017 and 0.625% for 2016. Management believes that the Company and Bank met all capital adequacy requirements to which they are subject as of March 31, 2017 and September 30, 2016. As of March 31, 2017, the most recent notification from the Federal Reserve Bank categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the Bank must maintain minimum total risk-based, Tier I risk-based, common equity Tier 1 risk-based and Tier I leverage ratios as set forth in the table below. There are no conditions or events since that notification that management believes have changed the Bank’s category. The Company’s and Bank’s actual capital amounts and ratios are also presented in the table. No amount was deducted from capital for interest-rate risk at either period.
