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 thereto that were included in the Company’s Annual Report for the year ended December 31, 2014. 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 2014 Annual Report. 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”). On September 12, 2014, Ben Franklin Financial filed a Registration Statement on Form S-1 with the Securities and Exchange Commission in connection with the mutual to stock conversion of Ben Franklin Financial, MHC and the related offering of common stock by Ben Franklin Financial, Inc. The Registration Statement (File No. 333-198702) was declared effective by the Securities and Exchange Commission on November 12, 2014. Ben Franklin Financial, Inc. registered 998,488 shares of common stock, par value $0.01 per share, pursuant to the Registration Statement. The stock offering commenced on November 21, 2014, and ended on January 8, 2015. The stock offering closed January 22, 2015 and resulted in gross proceeds of $3.9 million, through the sale of 390,474 shares of common stock, including 27,333 purchased by the ESOP, at a price of $10.00 per share. Expenses related to the offering were approximately $1.4 million. Net proceeds of the offering were approximately $2.5 million. As part of the conversion, the MHC’s ownership interest of the Company was offered for sale in a public offering. The existing publicly held shares of the Company, were exchanged for 0.3562 new shares of common stock of Ben Franklin Financial. The exchange ratio ensured that immediately after the conversion and public offering, the public shareholders of Company owned the same aggregate percentage of Ben Franklin Financial common stock that they owned immediately prior to that time (excluding shares purchased in the stock offering and cash received in lieu of fractional shares). When the conversion and public offering was completed, Ben Franklin Financial became the holding company of Ben Franklin Bank of Illinois and succeeded to all of the business and operations of the Company and each of the Company and the MHC ceased to exist. The financial statements do not include the transactions and balances of the MHC. Ben Franklin Financial, Inc. contributed $2.0 million of the net proceeds of the offering to the Bank. In addition, $273,000 of the net proceeds were used to fund the loan to the employee stock ownership plan and approximately $314,000 of the net proceeds were retained by Ben Franklin Financial, Inc. The net proceeds contributed to the Bank have been invested in interest earning deposits and investment securities, and are expected to be used for funding future loan growth. The net proceeds retained by Ben Franklin Financial, Inc. were deposited with the Bank.

Recent Losses and Management Plans	Note 2 – Recent Losses and Management Plans The Company incurred net losses of $787,000 during the nine months ended September 30, 2015 and $1.4 million during the year ended December 31, 2014. The losses are largely a result of our declining net interest income and increasing non-interest expense related to professional fees, and in 2014, write-downs on repossessed assets. Despite these losses, the Bank’s total capital to risk-based capital ratio and Tier 1 leverage capital to average assets ratio was 19.3% and 10.1% at September 30, 2015 and 15.5% and 8.7% at December 31, 2014. Due to our financial condition over the past several years, the Bank entered into a Consent Order (“Order”) with the Office of the Comptroller of the Currency (“OCC”) on December 19, 2012. The Order outlines areas of weakness that the Bank must improve related to asset quality including valuations, classifications, monitoring, concentrations, and allowance for loan losses; capital and strategic planning; liquidity management; consumer compliance; and management and board structure along with time frames for completion. The Order mandated that the Bank maintain a total risk-based capital ratio of at least 13% and a Tier 1 leverage ratio of at least 9% beginning on March 31, 2014. At September 30, 2015, the Bank was in compliance with the required minimum ratios. At December 31, 2014, prior to the completion of the Company’s stock offering, the Bank was not in compliance with the Tier 1 leverage ratio but was in compliance with the total risk based capital ratio. Management has initiated specific plans to reduce credit risk and improve the Bank’s regulatory capital ratios including the completion of the public offering in 2015. The Company has $335,000 and $43,000 of cash at September 30, 2015 and December 31, 2014. If the Bank is unable to meet the capital requirements and other requirements of the Order, the OCC may institute other corrective measures and has enforcement powers to impose additional restrictions on the Bank’s operations, including seizure. Although management believes that it will successfully maintain the required capital ratios, there can be no assurance that they will be able to do so, nor that they will be able to comply fully with the provisions of the Order. Only the OCC has the ability to determine whether or not the provisions of the Order have been met.

There were no securities pledged to secure any of the borrowings of the Company as of September 30, 2015 and December 31, 2014. The amortized cost and fair value of available-for-sale securities are shown by contractual maturity as of September 30, 2015. Expected maturities may differ from contractual maturities if borrowers have the right to call or prepay obligations with or without call or prepayment penalties. Securities not due at a single maturity date are shown separately.

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 status of the loan. The risk category of these loans is evaluated at origination, when a loan becomes delinquent or when a borrower requests a concession. 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.

There was one loan totaling $1,561 that paid off during the nine months ended September 30, 2015 which resulted in a $28 charge-off. There were no loans modified as troubled debt restructurings during the nine months ended September 30, 2015 or the year ended December 31, 2014. There were two loans modified as troubled debt restructurings but paying as agreed under the terms of the modification with a balance of $114 as of September 30, 2015, which are being reported as nonaccrual. There were three loans modified as troubled debt restructurings with a balance of $548 which are being reported as nonaccrual as of December 31, 2014, two of which totaling $448 are paying as agreed under the terms of the modification. A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms. There were no loans with payments in default during the nine months ended September 30, 2015. During the year ended December 31, 2014 one loan totaling $231, secured by a multi-family building, had payments in default and subsequently paid off resulting in a $60 recovery. The Company has allocated $99 to specific reserves on $1,281 of loans to customers whose loan terms have been modified in troubled debt restructurings as of September 30, 2015. At December 31, 2014, the Company has allocated $293 to specific reserves on $2,904 of loans to customers whose loan terms have been modified in troubled debt restructurings. The Company has not committed to lend additional amounts as of September 30, 2015 and December 31, 2014 to customers with outstanding loans that are classified as troubled debt restructurings.

Fair Value Disclosures [Abstract]
Fair Value Measures	Note 7 – 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 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 Available for Sale Impaired Loans Repossessed Assets 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.

The impaired loans resulted in a $55,000 provision for loan loss for the three and nine months ended September 30, 2015. At December 31, 2014, impaired loans had an aggregate balance of $2,653,000 with a $279,000 valuation allowance. The impaired loans resulted in no provision for loan loss for the three and nine months ended September 30, 2014. Repossessed assets, consisting of other real estate owned, repossessed automobiles, and other repossessed assets are measured at the lower of cost or fair value less costs to sell. Repossessed assets were carried at $476,000 at September 30, 2015 consisting of the cost basis of $644,000 and a valuation allowance of $168,000. Repossessed assets were carried at $504,000 at December 31, 2014, consisting of the cost basis of $657,000 and a valuation allowance of $153,000. There was $14,000 of write-downs on repossessed assets for the three and nine months ended September 30, 2015. There was $68,000 and $190,000 of write-downs for the three and nine months ended September 30, 2014, respectively.

Fair values for other loans are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality resulting in a Level 3 classification. Impaired loans are valued at the lower of cost or fair value as described previously. The methods utilized to estimate the fair value of loans do not necessarily represent an exit price. (c) FHLB Stock It is not practical to determine the fair value of FHLB stock due to restrictions placed on its transferability. (d) Accrued Interest Receivable The carrying amount of accrued interest receivable approximates its fair value and is classified as Level 2 for securities and Level 3 for loans. (e) Deposits The fair values disclosed for demand deposits (e.g., interest and non-interest demand, savings, and certain types of money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amount) and are classified as Level 1. The carrying amounts of variable rate certificates of deposit approximate their fair values at the reporting date are classified as a Level 2. Fair values for fixed rate certificates of deposit are estimated using a discounted cash flows calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits resulting in a Level 2 classification. (f) Accrued Interest Payable The carrying amount of accrued interest payable approximates its fair value and is classified as Level 2.

Regulatory Capital Matters

Regulatory Capital Matters	9 Months Ended

Banking and Thrift [Abstract]
Regulatory Capital Matters	Note 8 – Regulatory Capital Matters The Bank is 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 Bank’s operations and financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The 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 help ensure capital adequacy require the Bank to maintain minimum amounts and ratios of common equity, Tier I, and total capital as defined in the regulations to risk-weighted assets as defined and of Tier I capital to average total assets as defined. To be categorized as well capitalized, the Bank must maintain minimum common equity, Tier I risk-based, total risk-based, and Tier I leverage ratios. In March 2015, the Bank implemented the Basel III capital rules that reformed the regulatory capital framework. On December 19, 2012, the Bank entered into the Order with the OCC, which, among other things, included a requirement to maintain a total risk-based capital ratio of at least 13% and a minimum Tier 1 leverage capital ratio of at least 9% beginning on March 31, 2014. As a result of entering into the Order to achieve and maintain specific capital levels, the Bank’s capital classification under the Prompt Corrective Action rules was “adequately capitalized” at September 30, 2015 and December 31, 2014. Although the Bank’s capital levels at September 30, 2015 were above the levels required to be considered “well capitalized” under federal bank regulatory agency definitions, the Bank cannot be consider “well capitalized” as long as it remains under the Order. During 2014, the Bank met the risk-based capital requirement but did not meet the Tier 1 capital requirement. With the completion of the conversion and stock offering on January 22, 2015, the Company did meet the capital requirement of the Order at September 30, 2015. The minimum capital ratios set forth in the Order may be increased and other minimum capital requirements may be established to comply with the Basel III requirements now applicable to the Bank. The prompt corrective action regulations provide five classifications, including well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If undercapitalized, asset growth and expansion are limited and plans for capital restoration are required. Actual capital levels and minimum required levels for the Bank were: Actual Minimum Required Minimum Required Order (effective March 31, 2013) Amount Ratio Amount Ratio Amount Ratio (Dollars in thousands) September 30, 2015 Total capital (to risk-weighted assets) $ 9,442 19.3 % $ 3,911 8.0 % $ 6,355 13.0 % Common equity Tier 1 capital (to risk-weighted assets) 8,827 18.1 2,200 4.5 N/A N/A Tier 1 capital (to risk-weighted assets) 8,827 18.1 2,933 6.0 N/A N/A Tier 1 capital (to average total assets) 8,827 10.1 3,493 4.0 7,859 9.0 December 31, 2014 Total capital (to risk-weighted assets) $ 8,510 15.5 % $ 4,387 8.0 % $ 7,129 13.0 % Tier 1 (core) capital (to risk-weighted assets) 7,818 14.3 2,193 4.0 N/A N/A Tier 1 (core) capital (to adjusted total assets) 7,818 8.7 3,580 4.0 8,054 9.0 Under Basel III a capital conservation buffer of 2.5%, comprised of Common Equity Tier 1, is established above the regulatory minimum capital requirement. The capital conservation buffer will be phased in between January 1, 2016 and year end 2018 becoming fully effective on January 1, 2019. The Bank made the one-time AOCI opt-out election on the first Call Report filed after January 1, 2015, which allows community banks under $250 billion with a one-time opt-out election to remove the impact of certain unrealized capital gains and losses from the calculation of capital. There is no opportunity to change methodology in future periods.
