Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Financial Statement Presentation	Note 1 – Basis of Financial Statement Presentation The accompanying consolidated financial statements of Ben Franklin Financial, Inc. (the “Company”) and its wholly owned subsidiary Ben Franklin Bank of Illinois (the “Bank”) have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in accordance with SEC rules and regulations. Accordingly, the statements do not include all the information and footnotes required by GAAP for complete financial statements. These interim financial statements should be read in conjunction with the consolidated financial statements and notes that were included in the Company’s Annual Report for the year ended December 31, 2016 . All significant intercompany transactions are eliminated in consolidation. In the opinion of the Company’s management, all adjustments necessary (i) for a fair presentation of the financial statements for the interim periods included herein and (ii) to make such financial statements not misleading have been made and are of a normal and recurring nature. Interim results are not necessarily indicative of results for a full year. In preparing the financial statements, management is required to make estimates and assumptions that affect the recorded amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses for the period. Actual results could differ from those estimates. For further information with respect to significant accounting policies followed by the Company in preparation of the financial statements, refer to the Company’s 2016 The Bank is a federally chartered stock savings bank and a member of the Federal Home Loan Bank (“FHLB”) system. The Bank maintains insurance on deposit accounts with the Deposit Insurance Fund (“DIF”) of the Federal Deposit Insurance Corporation (“FDIC”).

Recurring Losses

Banking and Thrift [Abstract]
Recurring Losses	Note 2 – Recurring Losses and Regulatory Matters The Company has incurred losses since 2008 resulting from a combination of: declining net interest income, as our loan portfolio decreased from $109.8 million at December 31, 2008 to $62.3 million nine September 30, 2017 December 31, 2016 nine September 30, 2017 The Bank’s total capital to risk-based capital ratio and Tier 1 leverage capital to average assets ratio have continued to decline and were 11.3% and 7.0% respectively, at September 30, 2017 ratio of 8 12 September 30, 2017 the Bank was not in compliance with the Consent Order, and at that date we were considered less than adequately capitalized. At September 30, 2017, certificates of deposit scheduled to mature in one year or less from September 30, 2017 totaled $21.7 million, of which $12.9 million is at an interest rate that is 75 basis points above the national deposit rate published by the FDIC (the “Threshold”). In the past, we have been able to retain a significant portion of maturing deposits and meet current loan commitments. However, because we are subject to the Consent Order, we must obtain the prior written approval of the FDIC in order to renew or rollover existing deposits that exceed the Threshold, as well as to accept new deposits at interest rates that are above the Threshold. Under the Consent Order, the Bank is required to receive non-objection to a revised Capital and Strategic Plan (the "Strategic Plan"). On January 30, 2017, the Bank submitted to the OCC a revised Strategic Plan. By letter dated March 2, 2017, the OCC informed the Bank that it would not grant its non-objection to the Strategic Plan as submitted by the Bank. On August 31, 2017, the Bank submitted a revised Strategic Plan to the OCC to which the OCC has not yet responded. If the Bank is not able to comply with the requirements of the Consent Order regarding the Strategic Plan or the Bank's capital levels, the OCC may institute other corrective measures and has enforcement power to impose other restrictions on the Bank's operations, including seizure. Only the OCC has authority to determine whether or not the provisions of the Consent Order have been met.

New Accounting Standards

Accounting Policies [Abstract]
New Accounting Standards	Note 3 – New Accounting Standards In May 2014, the FASB released ASU 2014-09, Revenue from Contracts with Customers (Topic 606) which implements a common revenue standard that clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 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. To achieve that core principle, an entity should apply the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. In July 2015, FASB deferred the effective date of the ASU by one year which means ASU 2014-09 will be effective for the Company on January 1, 2018. Management has concluded that the ASU will not materially In June 2016 the FASB issued accounting standards update 2016-13, Measurement of Credit Losses on Financial Instruments. The main objective of this update is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this objective, the amendments in this update replace the incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments affect entities holding financial assets and net investment in leases that are not accounted for at fair value through net income. The amendments affect loans, debt securities classified as held to maturity, trade receivables, net investments in leases, off-balance-sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. The provisions of this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Management is identifying the loan data needed for adoption of this update; however, Management has not yet determined the impacts of this update on the Company’s financial position or results of operations.

The amortized cost and fair value of available-for-sale securities are shown by contractual maturity as of September 30, 2017 . Expected maturities may differ from contractual maturities if borrowers have the right to call or prepay obligations with or without call or prepayment penalties.

Unrealized losses on securities have not been recognized into income because the issuer’s securities are of high credit quality (rated AA or higher at the time of purchase), management does not intend to sell and it is not more likely than not that management would be required to sell the securities prior to their anticipated recovery, and the decline in fair value is largely due to changes in interest rates. The fair value is expected to recover as the securities approach maturity.

Credit Quality Indicators The Bank categorizes loans into risk categories based on relevant information about the ability of a borrower to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Bank analyzes loans individually by classifying the loans as to credit risk. The analysis includes the non-homogeneous loans, such as multi- family, commercial real estate, construction, and commercial loans. The analysis is performed on a quarterly basis. Homogeneous loans are monitored based on past due 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 institution 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. Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be pass rated loans. The following table reflects the risk category by loans at the dates indicated based on the most recent analysis performed.

Fair Value Disclosures [Abstract]
Fair Value Measures	Note 8 – Fair Value Measures 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 Level 1 Level 2 1 Level 3 The Company used the following methods and significant assumptions to estimate the fair value of each type of financial instrument: Securities Available for Sale : The fair values of securities available-for-sale are 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 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. Such adjustments are usually significant and typically result in a Level 3 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 Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted accordingly. Repossessed Assets : 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. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 Other real estate owned properties are evaluated on a quarterly basis for additional impairment and adjusted accordingly. Appraisals for both collateral-dependent impaired loans and other real estate owned are performed by certified appraisers whose qualifications and licenses have been reviewed and verified by the Company. Once received, management reviews the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics. Upon sale of collateral, the Company compares the actual selling price of collateral that has been sold to the most recent appraised value to determine what additional adjustment should be made to the appraisal value to arrive at fair value for the remaining assets carried at fair value. Assets Measured on a Recurring Basis Assets measured at fair value on a recurring basis are summarized below: Fair Value Measurements Using Balance Quoted Prices in Active Markets for Identical Assets (Level 1 Significant Other Observable Inputs (Level 2 Significant Unobservable Inputs (Level 3 September 30, 2017 Assets Securities available for sale U.S. government-sponsored entities $ 4,930 $ — $ 4,930 $ — Residential mortgaged-backed 836 — 836 — $ 5,766 $ — $ 5,766 $ — December 31, 2016 Assets Securities available for sale U.S. government-sponsored entities $ 6,873 $ — $ 6,873 $ — Residential mortgaged-backed 1,367 — 1,367 — $ 8,240 $ — $ 8,240 $ — There were no t 1 2 3 nine September 30, 2017 or the year ended December 31, 2016 .

Banking and Thrift [Abstract]
Regulatory Capital Matters	Note 9 – Regulatory Capital Matters The Bank is subject to various regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. The final rules implementing Basel Committee on Banking Supervision’s capital guidelines for U.S. banks (Basel Ill rules) became effective for the Company on January 1 2015 1 2019 Effective as of January 1 2016 on a 1 September 30, 2017 Quantitative measures established by regulation to help ensure capital adequacy require the Bank to maintain minimum amounts and ratios of total and Tier I capital as defined in the regulations to risk-weighted assets as defined and of Tier I capital to adjusted total assets as defined. To be categorized as well capitalized, the Bank must maintain minimum total risk-based, Tier I risk-based, and Tier I leverage ratios. On November 25 2015 educed 19 2012 1 The Company's board adopted resolutions requested by the Federal Reserve Board which prohibits us from paying dividends, increasing our debt, or redeeming shares of the Company without prior written approval from the Federal Reserve Board. As a result of entering into the Consent Order that requires the Bank to achieve and maintain specific capital levels, the Bank’s capital classification under the Prompt Corrective Action rules was “less than adequately capitalized” at September 30, 2017 and "adequately capitalized" at December 31, 2016 . As long as the Bank is subject to the Consent Order, the Bank cannot be considered “well capitalized”.

On January 24, 2017, the Company granted restricted stock awards for 15,619 common All of the options granted have an exercise price of $10.70 per share, which was the closing price of the stock on the grant date. No options were vested, exercised or forfeited as of September 30, 2017 September 30, 2017 The fair value of each option award is estimated on the date of grant using a closed form option valuation (Black-Scholes) model that uses the assumptions noted in the table below. Company’s expected volatility was based on historical stock price for the past two years. The expected term represents the period of time that options granted are expected to be outstanding, which takes into account that the options are not transferable. The risk-free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The fair value of each option granted in 2017 Risk free interest rate 2.27 % Expected term 7 Expected stock price volatility 20 % Dividend yield -0- % Stock option expense was $10 and $27 during the three and nine September 30, 2017 September 30, 2017 The fair value of the restricted stock awards was $10.70 per share, which was the closing price of the stock on the January 27, 2017 grant date.

Accounting Policies [Abstract]
New Accounting Standards	In May 2014, the FASB released ASU 2014-09, Revenue from Contracts with Customers (Topic 606) which implements a common revenue standard that clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 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. To achieve that core principle, an entity should apply the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. In July 2015, FASB deferred the effective date of the ASU by one year which means ASU 2014-09 will be effective for the Company on January 1, 2018. Management has concluded that the ASU will not materially In June 2016 the FASB issued accounting standards update 2016-13, Measurement of Credit Losses on Financial Instruments. The main objective of this update is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this objective, the amendments in this update replace the incurred loss impairment methodology with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments affect entities holding financial assets and net investment in leases that are not accounted for at fair value through net income. The amendments affect loans, debt securities classified as held to maturity, trade receivables, net investments in leases, off-balance-sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. The provisions of this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Management is identifying the loan data needed for adoption of this update; however, Management has not yet determined the impacts of this update on the Company’s financial position or results of operations.
