Summary of Significant Accounting Policies (Notes)	Mar. 31, 2015
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	Basis of Presentation: BankFinancial Corporation, a Maryland corporation headquartered in Burr Ridge, Illinois, is the owner of all of the issued and outstanding capital stock of BankFinancial, F.S.B. (the “Bank”).
	Principles of Consolidation: The interim unaudited consolidated financial statements include the accounts of and transactions of BankFinancial Corporation, the Bank, and the Bank’s wholly-owned subsidiaries, Financial Assurance Services, Inc. and BF Asset Recovery Corporation (collectively, “the Company”), and reflect all normal and recurring adjustments that are, in the opinion of management, considered necessary for a fair presentation of the financial condition and results of operations for the periods presented. All significant intercompany accounts and transactions have been eliminated. The results of operations for the three- month period ended March 31, 2015 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2015.
	Certain information and note disclosures normally included in financial statements prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission.
	Use of Estimates: To prepare financial statements in conformity with GAAP, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and future results could differ.
	Reclassifications: Certain reclassifications have been made in the prior period’s financial statements to conform them to the current period’s presentation.
	These unaudited consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2014, as filed with the Securities and Exchange Commission.

Earnings Per Share [Abstract]
Earnings Per Share [Text Block]	Amounts reported in earnings per share reflect earnings available to common stockholders for the period divided by the weighted average number of shares of common stock outstanding during the period, exclusive of unearned ESOP shares and unvested restricted stock shares. Stock options and restricted stock are regarded as potential common stock and are considered in the diluted earnings per share calculations to the extent that they would have a dilutive effect if converted to common stock.

The Company evaluates marketable investment securities with significant declines in fair value on a quarterly basis to determine whether they should be considered other-than-temporarily impaired under current accounting guidance, which generally provides that if a marketable security is in an unrealized loss position, whether due to general market conditions or industry or issuer-specific factors, the holder of the securities must assess whether the impairment is other-than-temporary.
Certain residential mortgage-backed securities and certain collateralized mortgage obligations that the Company holds in its investment portfolio were in an unrealized loss position at March 31, 2015, but the unrealized losses were not considered significant under the Company’s impairment testing methodology. In addition, the Company does not intend to sell these securities, and it is likely that the Company will not be required to sell these securities before their anticipated recovery occurs.

Nonaccrual loans and impaired loans are defined differently. Some loans may be included in both categories, and some may only be included in one category. Nonaccrual loans include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans.
The Company’s reserve for uncollected loan interest was $404,000 and $464,000 at March 31, 2015 and December 31, 2014, respectively. When a loan is on non-accrual status and the ultimate collectability of the total principal of an impaired loan is in doubt, all payments are applied to principal under the cost recovery method. Alternatively, when a loan is on non-accrual status but there is doubt concerning only the ultimate collectability of interest, contractual interest is credited to interest income only when received, under the cash basis method pursuant to the provisions of FASB ASC 310–10, as applicable. In all cases, the average balances are calculated based on the month–end balances of the financing receivables within the period reported pursuant to the provisions of FASB ASC 310–10, as applicable.

The Company evaluates loan extensions or modifications in accordance with FASB ASC 310–40 with respect to the classification of the loan as a TDR. In general, if the Company grants a loan extension or modification to a borrower for other than an insignificant period of time that includes a below–market interest rate, principal forgiveness, payment forbearance or other concession intended to minimize the economic loss to the Company, the loan extension or loan modification is classified as a TDR. In cases where borrowers are granted new terms that provide for a reduction of either interest or principal then due and payable, management measures any impairment on the restructured loan in the same manner as for impaired loans as noted above.
The Company had $3.0 million of TDRs at March 31, 2015 and December 31, 2014, with $26,000 and $38,000 in specific valuation reserves allocated to those loans at March 31, 2015 and December 31, 2014, respectively. The Company had no outstanding commitments to borrowers whose loans were classified as TDRs at either date.
The following table presents loans classified as TDRs:

Total troubled debt restructured loans	$	3,003			$	3,003

During the three months ending March 31, 2015 and 2014, the terms of certain loans were modified and classified as TDRs. The modification of the terms of such loans included one or a combination of the following: a reduction of the stated interest rate of the loan; an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk; or a permanent reduction of the recorded investment in the loan.
The following tables present TDR activity:

The TDRs described above had no material impact on interest income, resulted in no change to the allowance for loan losses allocated and resulted in no charge-offs for the three months ended March 31, 2015. The TDRs had no material impact on interest income, resulted in no change to the allowance for loan losses allocated and resulted in charge-offs of $41,000 for the three months ended March 31, 2014.
The following table presents TDRs for which there was a payment default during the three months ending March 31, 2015 and 2014 within twelve months following the modification.

A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms.
The TDRs for which there was a payment default resulted in no change to the allowance for loan losses allocated and resulted in no charge-offs during the three months ending March 31, 2015.
There were certain other loan modifications during the three months ending March 31, 2015 and 2014 that did not meet the definition of a TDR. These loans had a total recorded investment of $1.1 million and $739,000 at March 31, 2015 and 2014, respectively. The modification of these loans involved either a modification of the terms of a loan to borrowers who were not experiencing financial difficulties or a delay in a payment that was considered to be insignificant.
In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under the Company’s internal underwriting policy.
The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, including current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans based on credit risk. This analysis includes non-homogeneous loans, such as commercial and commercial real estate loans. This analysis is performed on a monthly basis. The Company uses the following definitions for risk ratings:
Special Mention. A Special Mention asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date. Special Mention assets are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification.
Substandard. Loans categorized as Substandard continue to accrue interest, but exhibit a well-defined weakness or weaknesses that may jeopardize the liquidation of the debt. The loans continue to accrue interest because they are well secured and collection of principal and interest is expected within a reasonable time. The risk rating guidance published by the Office of the Comptroller of the Currency clarifies that a loan with a well-defined weakness does not have to present a probability of default for the loan to be rated Substandard, and that an individual loan’s loss potential does not have to be distinct for the loan to be rated Substandard.
Nonaccrual. An asset classified Nonaccrual has all the weaknesses inherent in one classified 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. The loans were placed on nonaccrual status.
Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered “Pass” rated loans.
As of March 31, 2015, based on the most recent analysis performed, the risk categories of loans by class of loans are as follows:

Fair Value (Notes)	3 Months Ended
	Mar. 31, 2015
Fair Value Disclosures [Abstract]
Fair Value	Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values:

	•	Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date.

	•	Level 2 – Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

	•	Level 3 – Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.
	The Company used the following methods and significant assumptions to estimate the fair value of each type of financial instrument:
	Securities: The fair values of marketable equity securities are generally determined by quoted prices, in active markets, for each specific security (Level 1). If Level 1 measurement inputs are not available for a marketable equity security, we determine its fair value based on the quoted price of a similar security traded in an active market (Level 2). The fair values of debt securities are generally determined by matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities, but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2).
	Loans Held for Sale: Loans held for sale are carried at the lower of cost or fair value, which is evaluated on a pool-level basis. The fair value of loans held for sale is determined using quoted prices for similar assets, adjusted for specific attributes of that loan or other observable market data, such as outstanding commitments from third party investors (Level 2).
	Impaired Loans: The fair value of impaired loans with specific allocations of the allowance for loan losses is generally based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available for similar loans and collateral underlying such loans. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted in accordance with the allowance policy.
	Other Real Estate Owned: Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. Fair value is commonly based on recent real estate appraisals which are updated no less frequently than annually. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach with data from comparable properties. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Real estate owned properties are evaluated on a quarterly basis for additional impairment and adjusted accordingly.
	Mortgage Servicing Rights: On a quarterly basis, loan servicing rights are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. The fair values of mortgage servicing rights are based on a valuation model that calculates the present value of estimated net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income. The Company is able to compare the valuation model inputs and results to widely available published industry data for reasonableness (Level 2).
	The following table sets forth the Company’s financial assets that were accounted for at fair value and are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

Impaired loans which are measured for impairment using the fair value of the collateral for collateral–dependent loans, and have specific valuation allowances, had a carrying amount of $6.1 million, with a valuation allowance of $451,000 at March 31, 2015, compared to a carrying amount of $4.8 million, and a valuation allowance of $470,000 at December 31, 2014, resulting in an decrease in the provision for loan losses of $19,000 for the three months ended March 31, 2015. There was an increase in the provision for loan losses of $114,000 for the three months ended March 31, 2014.
Other real estate owned ("OREO"), which is carried at the lower of cost or fair value less costs to sell, had a carrying value of $994,000 less a valuation allowance of $213,000, or $781,000 at March 31, 2015, compared to a carrying value of $3.0 million less a valuation allowance of $803,000, or $2.2 million at December 31, 2014. There were $213,000 of valuation adjustments of OREO recorded for the three months ended March 31, 2015. There were $44,000 of valuation adjustments of OREO recorded for the three months ended March 31, 2014.
Mortgage servicing rights, which are carried at lower of cost or fair value, had a carrying amount of $158,000 at March 31, 2015, and a carrying amount of $160,000 at December 31, 2014. A pre-tax recovery of $10,000 on our mortgage servicing rights portfolio was included in noninterest income for the three months ended March 31, 2015, compared to a provision of $4,000 for the same period in 2014.

For purposes of the above, the following assumptions were used:
Cash and Cash Equivalents: The estimated fair values for cash and cash equivalents are based on their carrying value due to the short-term nature of these assets.
Loans: The estimated fair value for loans has been determined by calculating the present value of future cash flows based on the current rate the Company would charge for similar loans with similar maturities, applied for an estimated time period until the loan is assumed to be repriced or repaid. The estimated fair values of loans held for sale are based on quoted market prices.
FHLBC Stock: It is not practicable to determine the fair value of FHLBC stock due to the restrictions placed on its transferability.
Deposit Liabilities: The estimated fair value for certificates of deposit has been determined by calculating the present value of future cash flows based on estimates of rates the Company would pay on such deposits, applied for the time period until maturity. The estimated fair values of noninterest-bearing demand, NOW, money market, and savings deposits are assumed to approximate their carrying values as management establishes rates on these deposits at a level that approximates the local market area. Additionally, these deposits can be withdrawn on demand.
Borrowings: The estimated fair values of advances from the FHLBC and notes payable are based on current market rates for similar financing. The estimated fair value of securities sold under agreements to repurchase is assumed to equal its carrying value due to the short-term nature of the liability.
Accrued Interest: The estimated fair values of accrued interest receivable and payable are assumed to equal their carrying value.
Off-*Balance-Sheet Instruments*: Off-balance-sheet items consist principally of unfunded loan commitments, standby letters of credit, and unused lines of credit. The estimated fair values of unfunded loan commitments, standby letters of credit, and unused lines of credit are not material.
While the above estimates are based on management’s judgment of the most appropriate factors, as of the balance sheet date, there is no assurance that the estimated fair values would have been realized if the assets were disposed of or the liabilities settled at that date, since market values may differ depending on the various circumstances. The estimated fair values would also not apply to subsequent dates.
In addition, other assets and liabilities that are not financial instruments, such as premises and equipment, are not included in the above disclosures.

Uncollected Interest Policy	The Company’s reserve for uncollected loan interest was $404,000 and $464,000 at March 31, 2015 and December 31, 2014, respectively. When a loan is on non-accrual status and the ultimate collectability of the total principal of an impaired loan is in doubt, all payments are applied to principal under the cost recovery method. Alternatively, when a loan is on non-accrual status but there is doubt concerning only the ultimate collectability of interest, contractual interest is credited to interest income only when received, under the cash basis method pursuant to the provisions of FASB ASC 310–10, as applicable. In all cases, the average balances are calculated based on the month–end balances of the financing receivables within the period reported pursuant to the provisions of FASB ASC 310–10, as applicable.
Reclassifications	Reclassifications: Certain reclassifications have been made in the prior period’s financial statements to conform them to the current period’s presentation.

Recent Accounting Pronouncements	Recent Accounting Pronouncements
	In January 2014, the FASB amended existing guidance to clarify when a creditor should derecognize a loan receivable and recognized collateral asset. An in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, the amendment requires interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. This amendment is effective for interim and annual reporting periods beginning after December 15, 2014. The adoption of this standard did not have a material impact on the Company’s results of operation or financial position.
	FASB ASC 606 - In May 2014, the FASB issued an update (ASU No. 2014-09, Revenue from Contracts with Customers) creating FASB Topic 606, Revenue from Contracts with Customers. The guidance in this update affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards (for example, insurance contracts or lease contracts). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance provides steps to follow to achieve the core principle. An entity should disclose sufficient information to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Qualitative and quantitative information is required about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. The amendments in this update will become effective for annual periods and interim periods within those annual periods beginning after December 15, 2016. We are currently evaluating the impact of adopting the new guidance on the consolidated financial statements.

The Company evaluates marketable investment securities with significant declines in fair value on a quarterly basis to determine whether they should be considered other-than-temporarily impaired under current accounting guidance, which generally provides that if a marketable security is in an unrealized loss position, whether due to general market conditions or industry or issuer-specific factors, the holder of the securities must assess whether the impairment is other-than-temporary.
Certain residential mortgage-backed securities and certain collateralized mortgage obligations that the Company holds in its investment portfolio were in an unrealized loss position at March 31, 2015, but the unrealized losses were not considered significant under the Company’s impairment testing methodology. In addition, the Company does not intend to sell these securities, and it is likely that the Company will not be required to sell these securities before their anticipated recovery occurs.

Nonaccrual loans and impaired loans are defined differently. Some loans may be included in both categories, and some may only be included in one category. Nonaccrual loans include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans.
The Company’s reserve for uncollected loan interest was $404,000 and $464,000 at March 31, 2015 and December 31, 2014, respectively. When a loan is on non-accrual status and the ultimate collectability of the total principal of an impaired loan is in doubt, all payments are applied to principal under the cost recovery method. Alternatively, when a loan is on non-accrual status but there is doubt concerning only the ultimate collectability of interest, contractual interest is credited to interest income only when received, under the cash basis method pursuant to the provisions of FASB ASC 310–10, as applicable. In all cases, the average balances are calculated based on the month–end balances of the financing receivables within the period reported pursuant to the provisions of FASB ASC 310–10, as applicable.

The Company evaluates loan extensions or modifications in accordance with FASB ASC 310–40 with respect to the classification of the loan as a TDR. In general, if the Company grants a loan extension or modification to a borrower for other than an insignificant period of time that includes a below–market interest rate, principal forgiveness, payment forbearance or other concession intended to minimize the economic loss to the Company, the loan extension or loan modification is classified as a TDR. In cases where borrowers are granted new terms that provide for a reduction of either interest or principal then due and payable, management measures any impairment on the restructured loan in the same manner as for impaired loans as noted above.
The Company had $3.0 million of TDRs at March 31, 2015 and December 31, 2014, with $26,000 and $38,000 in specific valuation reserves allocated to those loans at March 31, 2015 and December 31, 2014, respectively. The Company had no outstanding commitments to borrowers whose loans were classified as TDRs at either date.
The following table presents loans classified as TDRs:


	March 31, 2015				December 31, 2014
One-to-four family residential real estate	$	1,860			$	1,917

Multi-family mortgage	513				510

Multi-family mortgage	340				346

Troubled debt restructured loans – nonaccrual loans	630				576

Total troubled debt restructured loans	$	3,003			$	3,003

During the three months ending March 31, 2015 and 2014, the terms of certain loans were modified and classified as TDRs. The modification of the terms of such loans included one or a combination of the following: a reduction of the stated interest rate of the loan; an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk; or a permanent reduction of the recorded investment in the loan.
The following tables present TDR activity:

The TDRs described above had no material impact on interest income, resulted in no change to the allowance for loan losses allocated and resulted in no charge-offs for the three months ended March 31, 2015. The TDRs had no material impact on interest income, resulted in no change to the allowance for loan losses allocated and resulted in charge-offs of $41,000 for the three months ended March 31, 2014.
The following table presents TDRs for which there was a payment default during the three months ending March 31, 2015 and 2014 within twelve months following the modification.

A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms.
The TDRs for which there was a payment default resulted in no change to the allowance for loan losses allocated and resulted in no charge-offs during the three months ending March 31, 2015.
There were certain other loan modifications during the three months ending March 31, 2015 and 2014 that did not meet the definition of a TDR. These loans had a total recorded investment of $1.1 million and $739,000 at March 31, 2015 and 2014, respectively. The modification of these loans involved either a modification of the terms of a loan to borrowers who were not experiencing financial difficulties or a delay in a payment that was considered to be insignificant.
In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under the Company’s internal underwriting policy.
The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, including current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans based on credit risk. This analysis includes non-homogeneous loans, such as commercial and commercial real estate loans. This analysis is performed on a monthly basis. The Company uses the following definitions for risk ratings:
Special Mention. A Special Mention asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date. Special Mention assets are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification.
Substandard. Loans categorized as Substandard continue to accrue interest, but exhibit a well-defined weakness or weaknesses that may jeopardize the liquidation of the debt. The loans continue to accrue interest because they are well secured and collection of principal and interest is expected within a reasonable time. The risk rating guidance published by the Office of the Comptroller of the Currency clarifies that a loan with a well-defined weakness does not have to present a probability of default for the loan to be rated Substandard, and that an individual loan’s loss potential does not have to be distinct for the loan to be rated Substandard.
Nonaccrual. An asset classified Nonaccrual has all the weaknesses inherent in one classified 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. The loans were placed on nonaccrual status.
Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered “Pass” rated loans.
As of March 31, 2015, based on the most recent analysis performed, the risk categories of loans by class of loans are as follows:
