Organization and Summary of Significant Accounting Policies [Abstract]
Organization and Summary of Significant Accounting Policies	Note 1: Organization and Summary of Significant Accounting Policies Organization and Nature of Operations SB Financial Group, Inc. (the “Company”) is a bank holding company whose principal activity is the ownership and management of its wholly-owned subsidiaries, The State Bank and Trust Company (“State Bank”), RFCBC, Inc. (“RFCBC”), Rurbanc Data Services, Inc. dba RDSI Banking Systems (“RDSI”), and Rurban Statutory Trust II (“RST II”). State Bank owns all the outstanding stock of Rurban Mortgage Company (“RMC”), and State Bank Insurance, LLC (“SBI”). The Company is primarily engaged in providing a full range of banking and wealth management services to individual and corporate customers primarily located in Northwest Ohio and Northeast Indiana. The Company is subject to competition from other financial institutions, and regulated by certain federal and state agencies and undergoes periodic examinations by those regulatory authorities. Principles of Consolidation The Consolidated Financial Statements include the accounts of the Company, State Bank, RFCBC, RDSI, RMC, and SBI. All significant intercompany accounts and transactions were eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported 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 during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, loan servicing rights, valuation of deferred tax assets, other-than-temporary impairment and fair value of financial instruments. Cash Equivalents The Company considers all liquid investments with original maturities of three months or less to be cash equivalents. At December 31, 2017 and 2016, cash equivalents consisted primarily of interest bearing and noninterest bearing demand deposit balances held by correspondent banks. At December 31, 2017, none of the Company’s correspondent cash accounts exceeded federally insured limits. Additionally, the Company had approximately $15.6 million of cash held by the Federal Reserve Bank, which is not federally insured. Securities Available-for-sale securities, which include any security for which the Company has no immediate plan to sell but which may be sold in the future, are carried at fair value. Unrealized gains and losses are recorded, net of related income tax effects, in other comprehensive income. Amortization of premiums and accretion of discounts are recorded as interest income from securities. Realized gains and losses are recorded as net security gains (losses). Gains and losses on sales of securities are determined on the specific-identification method. For debt securities with fair value below carrying value when the Company does not intend to sell the debt security, and it is more likely than not the Company will not have to sell the security before recovery of its cost basis, the Company recognizes the credit component of an other-than-temporary impairment of the debt security in earnings and the remaining portion in other comprehensive income. Mortgage Loans Held for Sale Mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or fair value in the aggregate. Net unrealized losses, if any, are recognized through a valuation allowance by charges to noninterest income. Gains and losses on loan sales are recorded in noninterest income. Loans Loans that management has the intent and ability to hold for the foreseeable future, or until maturity or payoffs, are reported at their outstanding principal balances adjusted for any charge offs, the allowance for loan losses, any deferred fees or costs on originated loans and unamortized premiums or discounts on purchased loans. Interest income is reported on the interest method and includes amortization of net deferred loan fees and costs over the loan term. Generally, loans are placed on nonaccrual status not later than 90 days past due. Past due status is based on the contractual terms of the loan. All interest accrued, but not collected for loans that are placed on nonaccrual or charged off, is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Allowance for Loan Losses The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to income. Loan losses are charged against the allowance when management believes the non-collectability of a loan balance is probable. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as new information becomes available. The allowance consists of allocated and general components. The allocated component relates to loans that are classified as impaired. For those loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers non-classified loans and is based on historical charge off experience and expected loss given default derived from the Company’s internal risk rating process. Other adjustments may be made to the allowance for pools of loans after an assessment of internal or external influences on credit quality that are not fully reflected on the historical loss or risk rating data. A loan is considered impaired when, based on current information and events, it is probable that State Bank will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration each of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial, agricultural, and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price or the fair value of the collateral if the loan is collateral dependent. When State Bank moves a loan to nonaccrual status, total unpaid interest accrued to date is reversed from income. Subsequent payments are applied to the outstanding principal balance with the interest portion of the payment recorded on the balance sheet as a contra-loan. Interest received on impaired loans may be realized once all contractual principal amounts are received or when a borrower establishes a history of six consecutive timely principal and interest payments. It is at the discretion of Management to determine when a loan is placed back on accrual status upon receipt of six consecutive timely payments. Large groups of smaller balance homogenous loans are collectively evaluated for impairment. Accordingly, State Bank does not separately identify individual consumer and residential loans for impairment measurements, unless such loans are the subject of a restructuring agreement due to financial difficulties of the borrower. Premises and Equipment Depreciable assets are stated at cost less accumulated depreciation. Depreciation is charged to expense using the straight-line method for buildings and equipment over the estimated useful lives of the assets. Leasehold improvements are capitalized and depreciated using the straight-line method over the terms of the respective leases. Long-lived Asset Impairment The Company evaluates the recoverability of the carrying value of long-lived assets whenever events or circumstances indicate the carrying amount may not be recoverable. If a long-lived asset is tested for recoverability and the undiscounted estimated future cash flows expected to result from the use and eventual disposition of the asset is less than the carrying amount of the asset, the asset’s cost is adjusted to fair value and an impairment loss is recognized as the amount by which the carrying amount of a long-lived asset exceeds its fair value. Federal Reserve and Federal Home Loan Bank Stock Federal Reserve and Federal Home Loan Bank stock are required investments for institutions that are members of the Federal Reserve and Federal Home Loan Bank systems. The required investment in the common stock is based on a predetermined formula, carried at cost and evaluated for impairment. Foreclosed Assets Held for Sale Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value less costs to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of the carrying amount or the fair value less cost to sell. Revenue and expenses from operations related to foreclosed assets and changes in the valuation allowance are included in net income or expense from foreclosed assets. Goodwill Goodwill is tested for impairment annually. If the implied fair value of goodwill is lower than its carrying amount, goodwill impairment is indicated and goodwill is written down to its implied fair value. Core Deposits and Other Intangibles Intangible assets are being amortized on a straight-line basis over weighted-average periods ranging from one to fifteen years. Such assets are periodically evaluated as to the recoverability of their carrying value. Purchased software is being amortized using the straight-line method over periods ranging from one to three years. Derivatives Derivatives are recognized as assets and liabilities on the consolidated balance sheet and measured at fair value. For exchange-traded contracts, fair value is based on quoted market prices. For non-exchange traded contracts, fair value is based on dealer quotes, pricing models, discounted cash flow methodologies or similar techniques for which the determination of fair value may require significant management judgment or estimation. Mortgage Servicing Rights Mortgage servicing assets are recognized separately when rights are acquired through purchase or through sale of financial assets. Under the servicing assets and liabilities accounting guidance (ASC 806-50), servicing rights from the sale or securitization of loans originated by the Company are initially measured at fair value at the date of transfer. The Company subsequently measures each class of servicing asset using the amortization method. Under the amortization method, servicing rights are amortized in proportion to and over the period of estimated net servicing income. The amortized assets are assessed for impairment based on fair value at each reporting date. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost of service, the discount rate, the custodial earning rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. These variables change from quarter to quarter as market conditions and projected interest rates change, and may have an adverse impact on the value of the mortgage servicing right and may result in a reduction to noninterest income. Each class of separately recognized servicing assets subsequently measured using the amortization method is evaluated and measured for impairment. Impairment is determined by stratifying rights into tranches based on predominant characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual tranche, to the extent that fair value is less than the carrying amount of the servicing assets for that tranche. The valuation allowance is adjusted to reflect changes in the measurement of impairment after the initial measurement of impairment. Changes in valuation allowances are reported with “Mortgage Loan Servicing Fees, net” on the income statement. Fair value in excess of the carrying amount of servicing assets for that stratum is not recognized. Servicing fee income is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. The amortization of mortgage servicing rights is netted against loan servicing fee income. Share-Based Employee Compensation Plan At December 31, 2017 and 2016, the Company had a share-based employee compensation plan, which is described more fully in Note 17 to the Consolidated Financial Statements. Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company – put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before the maturity or the ability to unilaterally cause the holder to return specific assets. Income Taxes The Company accounts for income taxes in accordance with income tax accounting guidance (ASC 740, Income Taxes). The income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. Uncertain tax positions are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 percent; the term “upon examination” also includes resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances and information available at the reporting date and is subject to management’s judgment. The Company recognizes interest and penalties on income taxes as a component of income tax expense. The Company files consolidated income tax returns with its subsidiaries. With a few exceptions, the Company is no longer subject to U.S. Federal, State and Local examinations by tax authorities for the years before 2014. As of December 31, 2017, the Company had no uncertain income tax positions. The Company uses the specific identification (or portfolio) method for reclassifying material stranded tax effects in accumulated other consolidated income (AOCI) to earnings. The Company elected to apply the provisions of ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. As a result, the Company reclassified $0.02 million from AOCI to retained earnings. Treasury Shares Treasury stock is stated at cost. Cost is determined by the weighted-average cost method. Earnings Per Share Earnings per common share is computed using the two-class method. Basic earnings per share represent income available to common shareholders divided by the weighted-average number of common shares outstanding during each period. Diluted earnings per share reflect additional potential common shares and convertible preferred shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Company relate solely to outstanding stock options which are determined using the treasury stock method and convertible preferred shares which are determined using the converted method. Treasury stock shares are not deemed outstanding for earnings per share calculations. Comprehensive Income Comprehensive income consists of net income and other comprehensive income, net of applicable income taxes. Other comprehensive income includes unrealized appreciation (depreciation) on available-for-sale securities, and unrealized and realized gains and losses in derivative financial instruments that qualify for hedge accounting. Accumulated other comprehensive income consists solely of the cumulative unrealized gains and losses on available-for-sale securities net of income tax. New and applicable accounting pronouncements: Accounting Standards Update (ASU) No. 2018-02: Reclassifications of Certain tax Effects from Accumulated Other Comprehensive Income (Topic 220) In February of 2018, the FASB issued guidance that requires a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 ASU No. 2017-12: Derivatives and Hedging (Topic 815) This ASU better aligns an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. The amendments in this ASU are effective for reporting periods beginning after December 15, 2018, and management does not believe the changes will have a material effect on the Company’s consolidated financial statements. ASU No. 2017-04: Intangibles – Goodwill and Other (Topic 350) This ASU simplifies the test for goodwill impairment. Specifically, these amendments eliminate Step 2 from the goodwill impairment test, and also eliminate the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. The amendments in this ASU are effective for annual goodwill impairment tests in fiscal years beginning after December 15, 2019, and management does not believe the changes will have a material effect on the Company’s accounting and disclosures. ASU No. 2016-13: Financial Instruments – Credit Losses (Topic 326) This ASU replaces the current GAAP incurred impairment methodology regarding credit losses 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 in this update affect an entity to varying degrees depending on the credit quality of the assets held by the entity, their duration, and how the entity applies current GAAP. The amendments in this ASU are effective for reporting periods beginning after December 15, 2019, and management will need further study to determine the impact on the Company’s consolidated financial statements. The Company implemented a process to track required data by utilizing accounting software in preparation for compliance. The adoption of ASU 2016-13 is likely to result in an increase in the allowance for loan losses as a result of changing from an “incurred loss” model, which encompasses allowances for current known and inherent losses within the portfolio, to an “expected loss” model, which encompasses allowances for losses expected to be incurred over the life of the portfolio. Furthermore, ASU 2016-13 will necessitate that we establish an allowance for expected credit losses on debt securities. While we are currently unable to reasonably estimate the impact of adopting ASU 2016-13, we expect that the impact of adoption will be significantly influenced by the composition, characteristics and quality of our loan and securities portfolios as well as the prevailing economic conditions and forecasts as of the adoption date. We anticipate being fully prepared for implementation by December 15, 2019. ASU No. 2016-09: Stock Compensation (Topic 718) This ASU affects all entities that issue share-based payment awards to their employees. The update is intended to simplify the accounting for these transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The Company adopted the amendments in this ASU, and management has determined that the impact on the Company’s consolidated financial statements is immaterial. ASU No. 2014-09: Revenue from Contracts with Customers (Topic 606) This ASU affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets unless those contracts are within the scope of other standards. The core principle is that an entity should recognize revenue in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Our revenue is comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014-09, and noninterest income. We have completed our evaluation of the impact of ASU 2014-09 on components of our noninterest income and have not found any significant changes to our methodology of recognizing revenue. As required by ASU 2014-09, we will adopt the standard in the first quarter of 2018 and, at the time of this filing, we do not anticipate recording a cumulative effect adjustment to opening retained earnings because the adjustment was determined to be insignificant. We will include newly applicable revenue disclosures in our Form 10-Q for the quarter ended March 31, 2018.

Earnings Per Share [Abstract]
Earnings Per Share	Note 2: Earnings Per Share Earnings per common share (EPS) is computed using the two-class method. Basic earnings per common share is computed by dividing net income available to common shareholders by the weighted-average number of common shares outstanding during the applicable period, excluding participating securities. Participating securities include non-vested restricted stock awards. Non-vested restricted stock awards are considered participating securities to the extent the holders of these securities receive non-forfeitable dividends at the same rate as holders of common shares. Diluted earnings per common share is computed using the weighted-average number of shares determined for the basic earnings per common share plus the convertible impact of preferred shares and the dilutive effect of stock compensation using the treasury stock method. EPS for the years ended December 31, 2017, 2016 and 2015 is computed as follows: Twelve Months Ended Dec., 31 ($ in thousands - except per share data) 2017 2016 2015 Distributed earnings allocated to common shares $ 1,363 $ 1,180 $ 982 Undistributed earnings allocated to common shares 8,714 6,620 5,676 Net earnings allocated to common shares 10,077 7,800 6,658 Net earnings allocated to participating securities 13 9 5 Dividends on convertible preferred shares 975 975 956 Net Income allocated to common shares and participating securities $ 11,065 $ 8,784 $ 7,619 Weighted average shares outstanding for basic earnings per share 4,817 4,877 4,884 Dilutive effect of stock compensation 74 47 88 Dilutive effect of convertible shares 1,460 1,452 1,451 Weighted average shares outstanding for diluted earnings per share 6,351 6,376 6,423 Basic earnings per common share $ 2.10 $ 1.60 $ 1.36 Diluted earnings per common share $ 1.74 $ 1.38 $ 1.19 There were no anti-dilutive shares in 2017 or 2016.

Securities delivered for repurchase agreements (not included above) were $19.1 million at December 31, 2017 and $14.6 million at December 31, 2016. Gross gains of $0.13 million, and gross losses of $0.01 million was a reclassification from accumulated other comprehensive income and is included in the net gain on sales of securities for 2017. Gross gains of $0.26 million was a reclassification from accumulated other comprehensive income and is included in the net gain on sales of securities in 2016. The related tax expense for net security gains for 2017 was $0.04 million and for 2016 was $0.09 million and was a reclassification from accumulated other comprehensive income and is included in the income tax expense line in the income statement. There were no realized gains or losses on available-for-sale securities in 2015. Certain investments in debt securities are reported in the financial statements at an amount less than their historical cost. Total fair value of these investments at December 31, 2017 and 2016, was $59.3 million and $52.2 million, respectively, which was approximately 72 percent and 58 percent, respectively, of the Company’s available for sale investment portfolio. Based on evaluation of available evidence, including recent changes in market interest rates, credit rating information and information obtained from regulatory filings, management believes the declines in fair value for these securities are temporary. Should the impairment of any of these securities become other than temporary, the cost basis of the investment will be reduced and the resulting loss recognized in net income in the period the other-than-temporary impairment is identified. The following tables present securities with unrealized losses at December 31, 2017 and 2016: ($ in thousands) Less than 12 Months 12 Months or Longer Total December 31, 2017 Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses Securities: U.S. Treasury and Government agencies $ 5,675 $ (27 ) $ 2,559 $ (42 ) $ 8,234 $ (69 ) Mortgage-backed securities 35,205 (319 ) 14,673 (371 ) 49,878 (690 ) State and political subdivisions 905 (4 ) 326 (14 ) 1,231 (18 ) $ 41,785 $ (350 ) $ 17,558 $ (427 ) $ 59,343 $ (777 ) ($ in thousands) Less than 12 Months 12 Months or Longer Total December 31, 2016 Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses Securities: U.S. Treasury and Government agencies $ 6,044 $ (52 ) $ - $ - $ 6,044 $ (52 ) Mortgage-backed securities 44,344 (607 ) 703 (29 ) 45,047 (636 ) State and political subdivisions 1,095 (39 ) - - 1,095 (39 ) $ 51,483 $ (698 ) $ 703 $ (29 ) $ 52,186 $ (727 ) The unrealized loss on the securities portfolio has increased by $0.05 million as of December 31, 2017, from the prior year. Management reviews these securities on a quarterly basis and has determined that no impairment exists. Management evaluates securities for other-than-temporary impairment at least on a quarterly basis, and more frequently when economic or market concern warrants such evaluation. When the Company does not intend to sell a debt security, and it is more likely than not the Company will not have to sell the security before recovery of its cost basis, it recognizes the credit component of an other-than-temporary impairment of a debt security in earnings and the remaining portion in other comprehensive income.

Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since a portion of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Each customer’s creditworthiness is evaluated on a case-by-case basis. The amount of collateral obtained, if deemed necessary, is based on management’s credit evaluation of the customer. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, commercial real estate and residential real estate. Standby letters of credit are conditional commitments issued by State Bank to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing and similar transactions. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers. Forward sale commitments are commitments to sell groups of residential mortgage loans that the Company originates or purchases as part of its mortgage banking activities. The Company commits to sell the loans at specified prices in a future period, typically within forty-five days. These commitments are acquired to reduce market risk on mortgage loans in the process of origination and mortgage loans held for sales since the Company is exposed to interest rate risk during the period between issuing a loan commitment and the sales of the loan into the secondary market. Listed below is a summary of loan commitments, unused lines of credit and standby letters of credit as of December 31, 2017 and 2016. ($ in thousands) 2017 2016 Loan commitments and unused lines of credit $ 170,437 $ 143,553 Standby letters of credit 1,643 708 Total $ 172,080 $ 144,261 There are various contingent liabilities that are not reflected in the consolidated financial statements, including claims and legal actions arising in the ordinary course of business. In the opinion of management, after consultation with legal counsel, the ultimate disposition of these matters is not expected to have a material effect on the Company’s consolidated financial condition or results of operations. The risk characteristics of each loan portfolio segment are as follows: Commercial and Agricultural Commercial and agricultural loans are primarily based on the identified cash flows of the borrower and secondarily on the underlying collateral provided by the borrower. The cash flows of borrowers, however, may not be as expected and the collateral securing these loans may fluctuate in value. Most commercial loans are secured by the assets being financed or other business assets, such as accounts receivable or inventory, and may include a personal guarantee. Short-term loans may be made on an unsecured basis. In the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its customers. Commercial Real Estate including Construction Commercial real estate loans are viewed primarily as cash flow loans and secondarily as loans secured by real estate. Commercial real estate lending typically involves higher loan principal amounts and the repayment of these loans is generally dependent on the successful operation of the property securing the loan or the business conducted on the property securing the loan. Commercial real estate loans may be more adversely affected by conditions in the real estate markets or in the general economy. The characteristics of properties securing the Company’s commercial real estate portfolio are diverse, but with geographic location almost entirely in the Company’s market area. Management monitors and evaluates commercial real estate loans based on collateral, geography and risk grade criteria. In general, the Company avoids financing single purpose projects unless other underwriting factors are present to help mitigate risk. In addition, management tracks the level of owner-occupied commercial real estate versus nonowner-occupied loans. Construction loans are underwritten utilizing feasibility studies, independent appraisal reviews and financial analysis of the developers and property owners. Construction loans are generally based on estimates of costs and value associated with the completed project. These estimates may be inaccurate. Construction loans often involve the disbursement of substantial funds with repayment substantially dependent on the success of the ultimate project. Sources of repayment for these types of loans may be pre-committed permanent loans from approved long-term lenders, sales of developed property or an interim loan commitment from the Company until permanent financing is obtained. These loans are closely monitored by on-site inspections and are considered to have higher risks than other real estate loans due to their ultimate repayment being sensitive to interest rate changes, governmental regulation of real property, general economic conditions and the availability of long-term financing. Residential and Consumer Residential and consumer loans consist of two segments – residential mortgage loans and personal loans. Residential mortgage loans are secured by 1-4 family residences and are generally owner-occupied, and the Company generally establishes a maximum loan-to-value ratio and requires private mortgage insurance if that ratio is exceeded. Home equity loans are typically secured by a subordinate interest in 1-4 family residences, and consumer personal loans are secured by consumer personal assets, such as automobiles or recreational vehicles. Some consumer personal loans are unsecured, such as small installment loans and certain lines of credit. Repayment of these loans is primarily dependent on the personal income of the borrowers, which can be impacted by economic conditions in their market areas, such as unemployment levels. Repayment can also be impacted by changes in property values on residential properties. Risk is mitigated by the fact that these loans are of smaller individual amounts and spread over a large number of borrowers.

The Company analyzes loans individually by classifying the loans as to credit risk. This analysis includes loans with an outstanding balance greater than $100,000 and non-homogeneous loans, such as commercial and commercial real estate loans. This analysis is performed on a quarterly basis. The Company uses the following definitions for risk ratings: Pass (grades 1 – 4): Special Mention (grade 5): Substandard (grade 6): Doubtful (grade 7): Loss (grade 8): Loans are considered uncollectable and of such little value that continuing to carry them as assets on the Company’s financial statement is not feasible. Loans will be classified as Loss when it is neither practical nor desirable to defer writing off or reserving all or a portion of a basically worthless asset, even though partial recovery may be possible at some time in the future.

A loan is considered impaired, in accordance with the impairment accounting guidance (ASC 310-10-35-16), when based on current information and events, it is probable State Bank will be unable to collect all amounts due from the borrower in accordance with the contractual terms of the loan. Impaired loans include nonperforming commercial loans but also include loans modified in troubled debt restructurings where concessions have been granted to borrowers experiencing financial difficulties. These concessions could include a reduction in the interest rate on the loan, payment extensions, forgiveness of principal, forbearance or other actions intended to maximize collection. The following tables present impaired loan activity for the twelve months ended December 31, 2017 and 2016 and 2015: Twelve Months Ended Recorded Unpaid Principal Related Average Recorded Interest Income Investment Balance Allowance Investment Recognized With no related allowance recorded: Commercial & Industrial $ - $ - $ - $ - $ - Commercial RE & Construction 696 722 - 756 34 Agricultural & Farmland - - - - - Residential Real Estate 752 795 - 1,460 67 Consumer & Other 110 110 - 128 9 With a specific allowance recorded: Commercial & Industrial - - - - - Commercial RE & Construction 689 689 146 713 - Agricultural & Farmland - - - - - Residential Real Estate 1,078 1,097 178 628 25 Consumer & Other 87 87 5 91 5 Totals: Commercial & Industrial $ - $ - $ - $ - $ - Commercial RE & Construction $ 1,385 $ 1,411 $ 146 $ 1,469 $ 34 Agricultural & Farmland $ - $ - $ - $ - $ - Residential Real Estate $ 1,830 $ 1,892 $ 178 $ 2,088 $ 92 Consumer & Other $ 197 $ 197 $ 5 $ 219 $ 14 Twelve Months Ended Recorded Unpaid Principal Related Average Recorded Interest Income Investment Balance Allowance Investment Recognized With no related allowance recorded: Commercial & Industrial $ - $ - $ - $ - $ - Commercial RE & Construction 637 637 - 655 24 Agricultural & Farmland - - - - - Residential Real Estate 1,248 1,290 - 1,470 70 Consumer & Other 129 129 - 151 11 With a specific allowance recorded: Commercial & Industrial 50 50 50 50 3 Commercial RE & Construction 941 941 119 1,010 45 Agricultural & Farmland - - - - - Residential Real Estate 671 672 124 751 30 Consumer & Other 119 118 7 123 7 Totals: Commercial & Industrial $ 50 $ 50 $ 50 $ 50 $ 3 Commercial RE & Construction $ 1,578 $ 1,578 $ 119 $ 1,665 $ 69 Agricultural & Farmland $ - $ - $ - $ - $ - Residential Real Estate $ 1,919 $ 1,962 $ 124 $ 2,221 $ 100 Consumer & Other $ 248 $ 247 $ 7 $ 274 $ 18 Twelve Months Ended Recorded Unpaid Principal Related Average Recorded Interest Income Investment Balance Allowance Investment Recognized With no related allowance recorded: Commercial & Industrial $ 126 $ 1,214 $ - $ 1,388 $ - Commercial RE & Construction 1,110 1,110 - 1,206 27 Agricultural & Farmland - - - - - Residential Real Estate 657 657 - 862 52 Consumer & Other 90 90 - 107 9 With a specific allowance recorded: Commercial & Industrial - - - - - Commercial RE & Construction 4,644 4,893 1,759 5,006 90 Agricultural & Farmland - - - - - Residential Real Estate 1,056 1,013 167 1,084 45 Consumer & Other 374 374 37 385 22 Totals: Commercial & Industrial $ 126 $ 1,214 $ - $ 1,388 $ - Commercial RE & Construction $ 5,754 $ 6,003 $ 1,759 $ 6,212 $ 117 Agricultural & Farmland $ - $ - $ - $ - $ - Residential Real Estate $ 1,713 $ 1,670 $ 167 $ 1,946 $ 97 Consumer & Other $ 464 $ 464 $ 37 $ 492 $ 31 Impaired loans less than $100,000 are included in groups of homogenous loans. These loans are evaluated based on delinquency status. Interest income recognized on a cash basis does not materially differ from interest income recognized on an accrual basis. Troubled Debt Restructured (TDR) Loans TDRs are modified loans where a concession was provided to a borrower experiencing financial difficulties. Loan modifications are considered TDRs when the concessions provided are not available to the borrower through either normal channels or other sources. However, not all loan modifications are TDRs. TDR Concession Types The Company’s standards relating to loan modifications consider, among other factors, minimum verified income requirements, cash flow analysis, and collateral valuations. Each potential loan modification is reviewed individually and the terms of the loan are modified to meet a borrower’s specific circumstances at a point in time. All loan modifications, including those classified as TDRs, are reviewed and approved. The types of concessions provided to borrowers include: ● Interest rate reduction: A reduction of the stated interest rate to a nonmarket rate for the remaining original life of the debt. The Company also may grant interest rate concessions for a limited timeframe on a case by case basis. ● Amortization or maturity date change beyond what the collateral supports, including a change that does any of the following: (1) Lengthens the amortization period of the amortized principal beyond market terms. This concession reduces the minimum monthly payment and increases the amount of the balloon payment at the end of the term of the loan. Principal is generally not forgiven. (2) Reduces the amount of loan principal to be amortized. This concession also reduces the minimum monthly payment and increases the amount of the balloon payment at the end of the term of the loan. Principal is generally not forgiven. (3) Extends the maturity date or dates of the debt beyond what the collateral supports. This concession generally applies to loans without a balloon payment at the end of the term of the loan. In addition, there may be instances where renewing loans potentially require non-market terms and would then be reclassified as TDRs. ● Other: A concession that is not categorized as one of the concessions described above. These concessions include, but are not limited to: principal forgiveness, collateral concessions, covenant concessions, and reduction of accrued interest. Principal forgiveness may result from any TDR modification of any concession type. The tables below present the activity of TDRs during the years ended December 31, 2017, 2016 and 2015: There was no new TDRs during the period ended December 31, 2017. There was no increase in the allowance for loan losses due to TDRs in the twelve-month period ended December 31, 2017.

Derivative Financial Instruments [Abstract]
Derivative Financial Instruments	Note 6: Derivative Financial Instruments The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company manages its exposures to a wide variety of business and operational risks primarily through management of its core business activities. The Company manages economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources and duration of its assets and liabilities and through the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing and duration of the Company’s known or expected cash payments principally related to certain variable-rate assets. The Company does not use derivatives for trading or speculative purposes. Derivatives not designated as hedges are not speculative and result from a service the Company provides to certain customers. The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting interest rate swaps that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. As of December 31, 2017, the notional amount of customer-facing swaps was approximately $39.3 million, as compared to $33.2 million at December 31, 2016. This amount is offset with third party counterparties, as described above. The Company has minimum collateral posting thresholds with its derivative counterparties. As of December 31, 2017, the Company had no cash posted as collateral. Fair Values of Derivative Instruments on the Balance Sheet The table below presents the fair value of the Company’s derivative financial instruments, as well as their classification on the Balance Sheet, as of December 31, 2017 and 2016.

Goodwill and Intangibles	Note 8: Goodwill and Intangibles The balance of goodwill as of December 31, 2017 and December 31, 2016 was $16.4 million. No changes in goodwill were noted during 2017 or 2016. Goodwill is tested on the last day of the last quarter of each calendar year. Impairment exists when a reporting unit’s carrying value of goodwill exceeds its fair value. At December 31, 2017, the Company’s reporting unit had positive equity and the Company elected to perform a qualitative assessment to determine if it was more likely than not that the fair value of the reporting unit exceeded its carrying value, including goodwill. The qualitative assessment indicated that it was more likely than not that the fair value of the reporting unit exceeded its carrying value, resulting in no impairment.

Under the reciprocal program that State Bank is currently participating in, customers agree to allow State Bank to place their deposits with other participating banks in the CDARS program in insurable amounts under $250,000. In exchange, other banks in the program agree to place their deposits with State Bank also in insurable amounts under $250,000.

Among other changes, the TCJA reduces the US Federal corporate tax rate from 35 percent to 21 percent. At December 31, 2017, the Company has substantially completed its accounting for the tax effects of enactment of the TCJA. For deferred tax assets and liabilities, amounts were remeasured based on the rates expected to reverse in the future, which is now 21 percent. As noted above, the Company realized a one-time tax credit due to the TCJA of $1.7 million in 2017. The Company continues to analyze certain aspects of the TCJA and further refinements are possible, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts, although we do not expect these adjustments to materially impact our financial statements.

To be categorized as well capitalized, State Bank must maintain capital ratios as set forth in the table below. There are no conditions or events since December 31, 2017 that management believes have changed State Bank’s capital classification. State Bank’s actual capital amounts and ratios are presented in the following table.

The capital conservation buffer is phasing in from 0.0 percent for 2015 to 2.50 percent for 2019. The capital conservation buffer was 1.25 percent at December 31, 2017. The net unrealized gain or loss on available-for-sale securities is not included in computing regulatory capital. Management believes as of December 31, 2017, State Bank met all capital adequacy requirements to which they are subject.

Employee Benefits [Abstract]
Employee Benefits	Note 16: Employee Benefits The Company has instituted a long-term incentive program (LTI), with the objective of rewarding senior management with restricted shares of the Company, in addition to the existing stock option program (see Note 16). The Company has a retirement savings 401(k) plan covering substantially all employees. Employees contributing up to 4 percent of their compensation receive a Company match of 100 percent of the employee’s contribution. Employee contributions are vested immediately and the Company’s matching contributions are fully vested after three years of employment. Employer contributions charged to expense for 2017, 2016 and 2015 were $0.5, $0.4 and $0.4 million, respectively. Also, the Company has Supplemental Executive Retirement Plan (“SERP”) Agreements with certain active and retired officers. The agreements provide monthly payments for up to 15 years that equal 15 percent to 25 percent of average compensation prior to retirement or death. The charges to expense for the current agreements were $0.2, $0.03 and $0.2 million for 2017, 2016 and 2015, respectively. Additional life insurance is provided to certain officers through a bank-owned life insurance policy (“BOLI”). By way of a separate split-dollar agreement, the policy interests are divided between State Bank and the insured’s beneficiary. State Bank owns the policy cash value and a portion of the policy net death benefit, over and above the cash value assigned to the insured’s beneficiary. The cash surrender value of all life insurance policies totaled $16.5 and $13.7 million at December 31, 2017, and 2016, respectively. The Company has a noncontributory employee stock ownership plan (“ESOP”) covering substantially all employees of the Company and its subsidiaries. Voluntary contributions are made by the Company to the plan. Each eligible employee is vested based upon years of service, including prior years of service. The Company’s contributions to the account of each employee become fully vested after three years of service. Benefit expense for the value of the stock purchased is recorded equal to the fair market value of the stock when contributions, which are determined annually by the Board of Directors of the Company, are made to the ESOP. Allocated shares in the ESOP at December 31, 2017 and 2016, were 449,635 and 466,442, respectively. Dividends on allocated shares are recorded as dividends and charged to retained earnings. Compensation expense is recorded equal to the fair market value of the stock when contributions, which are determined annually by the Board of Directors of the Company, are made to the ESOP. ESOP expense for the years ended December 31, 2017, 2016 and 2015 was $0.2, $0.3 and $0.2 million, respectively.

Share Based Compensation Plan [Abstract]
Share Based Compensation Plan	Note 17: Share Based Compensation Plan In April 2017, the shareholders approved a new share-based incentive compensation plan, the SB Financial Group, Inc. 2017 Stock Incentive Plan (the “2017 Plan”), which replaced the Company’s 2008 Stock Incentive Plan. This plan permits the grant or award of incentive stock options, nonqualified stock options, stock appreciation rights (“SAR’s”), restricted stock, and restricted stock units (“RSU’s”) for up to 500,000 Common Shares of the Company. The 2008 Plan, which was approved by the shareholders in April 2008, permits the grant or award of incentive stock options, nonqualified stock options, stock appreciation rights (“SARs”), and restricted stock for up to 250,000 Common Shares of the Company. The 2008 and 2017 Plans are intended to advance the interests of the Company and its shareholders by offering employees, directors and advisory board members of the Company and its subsidiaries an opportunity to acquire or increase their ownership interest in the Company through grants of equity-based awards. The Plans permit equity-based awards to be used to attract, motivate, reward and retain highly competent individuals upon whose judgment, initiative, leadership and efforts are key to the success of the Company by encouraging those individuals to become shareholders of the Company. Option awards are granted with an exercise price equal to the market price of the Company’s stock at the date of grant and those option awards vest based on 5 years of continuous service and have 10-year contractual terms. The fair value of each option award was estimated on the date of grant using the Black-Scholes valuation model. No options were granted in 2017, 2016 or 2015. There was no compensation expense charged against income with respect to option awards under the Plans for 2017, 2016 and 2015, respectively. A summary of incentive stock option activity under the Company’s plans as of December 31, 2017 and changes during the year then ended, is presented below: Shares Weighted- Weighted- Aggregate Outstanding, beginning of year 145,894 $ 8.12 Granted - - Exercised (42,517 ) 9.83 Forfeited (750 ) 6.98 Expired (10,127 ) 11.50 Outstanding, end of year 92,500 $ 6.97 2.12 $ 1,065,420 Exercisable, end of year 92,500 $ 6.97 2.12 $ 1,065,420 During 2017, the 42,517 option shares exercised had a total intrinsic value of $0.33 million and the cash received from these exercised options was $0.38 million. The tax benefit from these transactions was immaterial. As of December 31, 2017, there was no unrecognized compensation cost related to incentive option share-based compensation arrangements granted under the 2008 Plan. On February 5, 2013, the Company adopted a Long Term Incentive (LTI) Plan. The LTI Plan awards restricted stock in the Company to certain key executives under the 2008 and 2017 Plans. These restricted stock awards vest over a four-year period and are intended to assist the Company in retention of key executives. During 2017 and 2016, the Company met certain performance targets and restricted stock awards were approved by the Board. The compensation cost charged against income for the Long Term Incentive (LTI) Plan was $0.30, $0.13 and $0.08 million for 2017, 2016 and 2015, respectively. The total income tax benefit recognized in the income statement for share-based compensation arrangements was $0.10, $0.04 and $0.03 million for 2017, 2016 and 2015, respectively. A summary of restricted stock activity under the Company’s LTI Plan as of December 31, 2017 (issued under both the 2008 and 2017 plan) and changes during the year ended is presented below: Shares Weighted- Nonvested, beginning of year 35,503 $ 9.44 Granted 32,752 18.30 Vested (13,433 ) 9.03 Forfeited (2,564 ) 13.29 Nonvested, end of year 52,258 $ 14.91 As of December 31, 2017, there was $0.52 million of total unrecognized compensation cost related to non-vested share-based compensation arrangements related to the restricted stock awards under the 2008 and 2017 Plan which were granted in accordance with the Long Term Incentive (LTI) plan. That cost is expected to be recognized over a weighted-average period of 1.91 years.

Disclosures About Fair Value of Assets and Liabilities [Abstract]
Disclosures About Fair Value of Assets and Liabilities	Note 19: Disclosures About Fair Value of Assets and Liabilities ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value: Level 1: Level 2: Level 3 Following is a description of the valuation methodologies, inputs used for assets measured at fair value on a recurring basis, recognized in the accompanying balance sheets, as well as the general classification of such assets pursuant to the valuation hierarchy. Available for Sale Securities The fair value of available-for-sale securities are determined by various valuation methodologies. Level 1 securities include money market mutual funds. Level 1 inputs include quoted prices in an active market. Level 2 securities include U.S. government agencies, mortgage-backed securities and obligations of political and state subdivisions. Level 2 inputs do not include quoted prices for individual securities in active markets; however, they do include inputs that are either directly or indirectly observable for the individual security being valued. Such observable inputs include interest rates and yield curves at commonly quoted intervals, volatilities, prepayment speeds, credit risks and default rates. Also included are inputs derived principally from or corroborated by observable market data by correlation or other means. Interest Rate Contracts The fair values of interest rate contracts are based upon the estimated amount the Company would receive or pay to terminate the contracts or agreements, taking into account underlying interest rates, creditworthiness of underlying customers for credit derivatives and, when appropriate, the creditworthiness of the counterparties. The following table presents the fair value measurements of securities measured at fair value on a recurring basis and the level within ASC 820 fair value hierarchy in which the fair value measurements fell at December 31, 2017 and 2016: Fair Value Measurements Using: ($ in thousands) Fair Values at Available for Sale Securities: 12/31/2017 (Level 1) (Level 2) (Level 3) U.S. Treasury and Government Agencies $ 12,708 $ - $ 12,708 $ - Mortgage-backed securities 56,762 - 56,762 - State and political subdivisions 13,250 - 13,250 - Equity securities 70 - 70 - Interest rate contracts - assets 698 - 698 - Interest rate contracts - liabilities (698 ) - (698 ) - Fair Value Measurements Using: ($ in thousands) Fair Values at Available-for-Sale Securities: 12/31/2016 (Level 1) (Level 2) (Level 3) U.S. Treasury and Government Agencies $ 13,358 $ - $ 13,358 $ - Mortgage-backed securities 61,603 - 61,603 - State and political subdivisions 15,097 - 15,097 - Equity securities 70 - 70 - Interest rate contracts - assets 623 - 623 - Interest rate contracts - liabilities (623 ) - (623 ) - Level 1 - Quoted Prices in Active Markets for Identical Assets Level 2 - Significant Other Observable Inputs Level 3 - Significant Unobservable Inputs The following is a description of the valuation methodologies and inputs used for assets measured at fair value on a nonrecurring basis and recognized in the accompanying balance sheets, as well as the general classification of such assets pursuant to the valuation hierarchy. Collateral-dependent Impaired Loans, Net of ALLL Loans for which it is probable the Company will not collect all principal and interest due according to contractual terms are measured for impairment. The estimated fair value of collateral-dependent impaired loans is based on the appraised value of the collateral, less estimated cost to sell. Collateral-dependent impaired loans are classified within Level 3 of the fair value hierarchy. This method requires obtaining independent appraisals of the collateral, which are reviewed for accuracy and consistency by Credit Administration. These appraisers are selected from the list of approved appraisers maintained by management. The appraised values are reduced by applying a discount factor to the value based on the Company’s loan review policy. All impaired loans held by the Company were collateral dependent at December 31, 2017 and 2016. Mortgage Servicing Rights Mortgage servicing rights do not trade in an active, open market with readily observable prices. Accordingly, fair value is estimated using discounted cash flow models associated with the servicing rights and discounting the cash flows using discount market rates, prepayment speeds and default rates. The servicing portfolio has been valued using all relevant positive and negative cash flows including servicing fees, miscellaneous income and float; marginal costs of servicing; the cost of carry of advances; and foreclosure losses; and applying certain prevailing assumptions used in the marketplace. Due to the nature of the valuation inputs, mortgage servicing rights are classified within Level 3 of the hierarchy. These mortgage servicing rights are tested for impairment on a quarterly basis. The following table presents the fair value measurements of assets measured at fair value on a non-recurring basis and the level within the fair value hierarchy in which the fair value measurements fell at December 31, 2017 and 2016: ($ in thousands) Fair Values at Description 12/31/2017 (Level 1) (Level 2) (Level 3) Impaired loans $ 982 $ - $ - $ 982 Mortgage Servicing Rights 1,490 - - 1,490 ($ in thousands) Fair Values at Description 12/31/2016 (Level 1) (Level 2) (Level 3) Impaired loans $ 786 $ - $ - $ 786 Mortgage Servicing Rights 1,993 - - 1,993 Level 1 - Quoted Prices in Active Markets for Identical Assets Level 2 - Significant Other Observable Inputs Level 3 - Significant Unobservable Inputs Unobservable (Level 3) Inputs The following tables present quantitative information about unobservable inputs used in recurring and nonrecurring Level 3 fair value measurements at December 31, 2017 and 2016: Fair Value at Valuation Range (Weighted ($’s in thousands) 12/31/2017 Technique Unobservable Inputs Average) Collateral-dependent impaired loans $ 982 Market comparable properties Discounted cash flow Comparability adjustments (%) Not available Mortgage servicing rights 1,490 Discount Rate 9.65 % Constant prepayment rate 7.51 % P&I earnings credit 1.56 % T&I earnings credit 2.13 % Inflation for cost of servicing 1.50 % Fair Value at Valuation Range (Weighted ($’s in thousands) 12/31/2016 Technique Unobservable Inputs Average) Collateral-dependent impaired loans $ 786 Market comparable properties Discounted cash flow Comparability adjustments (%) Not available Mortgage servicing rights 1,993 Discount Rate 9.65 % Constant prepayment rate 7.61 % P&I earnings credit 0.76 % T&I earnings credit 1.60 % Inflation for cost of servicing 1.50 % The mortgage servicing rights portfolio is measured for fair value by an independent third party. The valuation of the portfolio hinges on a number of quantitative factors. These factors include, but are not limited to, a discount rate applied to the cash flows, and an assumption of future principal prepayments. The prepayment assumptions are based upon the historical performance of the Company’s portfolio as well as market metrics. With the increasing interest rates during 2017, the mortgage servicing rights have increased substantially in value. The servicing rights have had a decline in prepayments and the .10 percent decrease in the constant prepayment rate reflects the change in market rates. Absent the change in the discount rate, there were no other changes in the inputs or methodologies used to determine fair value at December 31, 2017, as compared to December 31, 2016. The following methods were used to estimate the fair value of all other financial instruments recognized in the accompanying balance sheets at amounts other than fair value. Cash and Due From Banks, Federal Reserve and Federal Home Loan Bank Stock and Interest Receivable and Payable Fair value is determined to be the carrying amount for these items (which include cash on hand, due from banks, and federal funds sold) because they represent cash or mature in 90 days or less, and do not represent unanticipated credit concerns. Loans Held for Sale The fair value of loans held for sale is based upon quoted market prices, where available, or is determined by discounting estimated cash flows using interest rates approximating the Company’s current origination rates for similar loans and adjusted to reflect the inherent credit risk. Loans The estimated fair value for loans receivable, net, is based on estimates of the rate State Bank would charge for similar loans at December 31, 2017 and 2016, applied for the time period until the loans are assumed to re-price or be paid. Mortgage Servicing Rights Mortgage servicing rights do not trade in an active, open market with readily observable prices. Accordingly, fair value is estimated using discounted cash flow models associated with the servicing rights and discounting the cash flows using discount market rates, prepayment speeds and default rates. The servicing portfolio has been valued using all relevant positive and negative cash flows including servicing fees, miscellaneous income and float; marginal costs of servicing; the cost of carry of advances; and foreclosure losses; and applying certain prevailing assumptions used in the marketplace. Due to the nature of the valuation inputs, mortgage servicing rights are classified within Level 3 of the hierarchy. These mortgage servicing rights are tested for impairment on a quarterly basis. Deposits, Repurchase Agreements & FHLB Advances Deposits include demand deposits, savings accounts and certain money market deposits. The carrying amount approximates the fair value. The estimated fair value for fixed-maturity time deposits, as well as borrowings, is based on estimates of the rate State Bank could pay on similar instruments with similar terms and maturities at December 31, 2017 and 2016. Loan Commitments The fair value of commitments is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. The estimated fair values for other financial instruments and off-balance-sheet loan commitments approximate cost at December 31, 2017 and 2016 and are not considered significant to this presentation. Trust Preferred Securities The fair value for Trust Preferred Securities is estimated by discounting the cash flows using an appropriate discount rate. The following table presents estimated fair values of the Company’s financial instruments. The fair values of certain instruments were calculated by discounting expected cash flows, which involves significant judgments by management and uncertainties. Fair value is the estimated amount at which financial assets or liabilities could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. Because no market exists for these financial instruments, and because management does not intend to sell these financial instruments, the Company does not know whether the fair values shown below represent values at which the respective financial instruments could be sold individually or in the aggregate.

Subsequent Events	Note 22: Subsequent Events Effective January 1, 2018 the Company completed the sale of the customer contracts and certain other assets of RDSI’s remaining processing business operated through its Diverse Computer Marketers (DCM) division. As part of the transaction, the Company entered into a 180 day transition agreement, which will allow the buyer to effectively convert the DCM clients to an alternative processing platform. The transaction is expected to have a minimal positive impact to the Company’s financial statements in 2018. On February 9, 2018, the Company closed a common share capital raise, pursuant to which the Company issued and sold an aggregate of 1,666,666 common shares in a public offering registered with the Securities and Exchange Commission at a price of $18.00 per share, resulting in gross proceeds of $30.0 million. After fees and transaction expenses, the Company realized net proceeds of $27.9 million. The Company intends to use the net proceeds from this offering for general corporate purposes, which may include (a) capital contributions to its bank subsidiary to increase regulatory capital and/or (b) investments at the holding company level.

Organization and Summary of Significant Accounting Policies (Policies)	12 Months Ended

Organization and Summary of Significant Accounting Policies [Abstract]
Nature of Operations	Organization and Nature of Operations SB Financial Group, Inc. (the “Company”) is a bank holding company whose principal activity is the ownership and management of its wholly-owned subsidiaries, The State Bank and Trust Company (“State Bank”), RFCBC, Inc. (“RFCBC”), Rurbanc Data Services, Inc. dba RDSI Banking Systems (“RDSI”), and Rurban Statutory Trust II (“RST II”). State Bank owns all the outstanding stock of Rurban Mortgage Company (“RMC”), and State Bank Insurance, LLC (“SBI”). The Company is primarily engaged in providing a full range of banking and wealth management services to individual and corporate customers primarily located in Northwest Ohio and Northeast Indiana. The Company is subject to competition from other financial institutions, and regulated by certain federal and state agencies and undergoes periodic examinations by those regulatory authorities.
Principles of Consolidation	Principles of Consolidation The Consolidated Financial Statements include the accounts of the Company, State Bank, RFCBC, RDSI, RMC, and SBI. All significant intercompany accounts and transactions were eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported 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 during the reporting period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for loan losses, valuation of real estate acquired in connection with foreclosures or in satisfaction of loans, loan servicing rights, valuation of deferred tax assets, other-than-temporary impairment and fair value of financial instruments.
Cash Equivalents	Cash Equivalents The Company considers all liquid investments with original maturities of three months or less to be cash equivalents. At December 31, 2017 and 2016, cash equivalents consisted primarily of interest bearing and noninterest bearing demand deposit balances held by correspondent banks. At December 31, 2017, none of the Company’s correspondent cash accounts exceeded federally insured limits. Additionally, the Company had approximately $15.6 million of cash held by the Federal Reserve Bank, which is not federally insured.
Securities	Securities Available-for-sale securities, which include any security for which the Company has no immediate plan to sell but which may be sold in the future, are carried at fair value. Unrealized gains and losses are recorded, net of related income tax effects, in other comprehensive income. Amortization of premiums and accretion of discounts are recorded as interest income from securities. Realized gains and losses are recorded as net security gains (losses). Gains and losses on sales of securities are determined on the specific-identification method. For debt securities with fair value below carrying value when the Company does not intend to sell the debt security, and it is more likely than not the Company will not have to sell the security before recovery of its cost basis, the Company recognizes the credit component of an other-than-temporary impairment of the debt security in earnings and the remaining portion in other comprehensive income.
Mortgage Loans Held for Sale	Mortgage Loans Held for Sale Mortgage loans originated and intended for sale in the secondary market are carried at the lower of cost or fair value in the aggregate. Net unrealized losses, if any, are recognized through a valuation allowance by charges to noninterest income. Gains and losses on loan sales are recorded in noninterest income.
Loans	Loans Loans that management has the intent and ability to hold for the foreseeable future, or until maturity or payoffs, are reported at their outstanding principal balances adjusted for any charge offs, the allowance for loan losses, any deferred fees or costs on originated loans and unamortized premiums or discounts on purchased loans. Interest income is reported on the interest method and includes amortization of net deferred loan fees and costs over the loan term. Generally, loans are placed on nonaccrual status not later than 90 days past due. Past due status is based on the contractual terms of the loan. All interest accrued, but not collected for loans that are placed on nonaccrual or charged off, is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses is established as losses are estimated to have occurred through a provision for loan losses charged to income. Loan losses are charged against the allowance when management believes the non-collectability of a loan balance is probable. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses is evaluated on a regular basis by management and is based upon management’s periodic review of the collectability of the loans in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as new information becomes available. The allowance consists of allocated and general components. The allocated component relates to loans that are classified as impaired. For those loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers non-classified loans and is based on historical charge off experience and expected loss given default derived from the Company’s internal risk rating process. Other adjustments may be made to the allowance for pools of loans after an assessment of internal or external influences on credit quality that are not fully reflected on the historical loss or risk rating data. A loan is considered impaired when, based on current information and events, it is probable that State Bank will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration each of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Impairment is measured on a loan-by-loan basis for commercial, agricultural, and construction loans by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price or the fair value of the collateral if the loan is collateral dependent. When State Bank moves a loan to nonaccrual status, total unpaid interest accrued to date is reversed from income. Subsequent payments are applied to the outstanding principal balance with the interest portion of the payment recorded on the balance sheet as a contra-loan. Interest received on impaired loans may be realized once all contractual principal amounts are received or when a borrower establishes a history of six consecutive timely principal and interest payments. It is at the discretion of Management to determine when a loan is placed back on accrual status upon receipt of six consecutive timely payments. Large groups of smaller balance homogenous loans are collectively evaluated for impairment. Accordingly, State Bank does not separately identify individual consumer and residential loans for impairment measurements, unless such loans are the subject of a restructuring agreement due to financial difficulties of the borrower.
Premises and Equipment	Premises and Equipment Depreciable assets are stated at cost less accumulated depreciation. Depreciation is charged to expense using the straight-line method for buildings and equipment over the estimated useful lives of the assets. Leasehold improvements are capitalized and depreciated using the straight-line method over the terms of the respective leases.
Long-lived Asset Impairment	Long-lived Asset Impairment The Company evaluates the recoverability of the carrying value of long-lived assets whenever events or circumstances indicate the carrying amount may not be recoverable. If a long-lived asset is tested for recoverability and the undiscounted estimated future cash flows expected to result from the use and eventual disposition of the asset is less than the carrying amount of the asset, the asset’s cost is adjusted to fair value and an impairment loss is recognized as the amount by which the carrying amount of a long-lived asset exceeds its fair value.
Federal Reserve and Federal Home Loan Bank Stock	Federal Reserve and Federal Home Loan Bank Stock Federal Reserve and Federal Home Loan Bank stock are required investments for institutions that are members of the Federal Reserve and Federal Home Loan Bank systems. The required investment in the common stock is based on a predetermined formula, carried at cost and evaluated for impairment.
Foreclosed Assets Held for Sale	Foreclosed Assets Held for Sale Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value less costs to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of the carrying amount or the fair value less cost to sell. Revenue and expenses from operations related to foreclosed assets and changes in the valuation allowance are included in net income or expense from foreclosed assets.
Goodwill	Goodwill Goodwill is tested for impairment annually. If the implied fair value of goodwill is lower than its carrying amount, goodwill impairment is indicated and goodwill is written down to its implied fair value.
Core Deposits and Other Intangibles	Core Deposits and Other Intangibles Intangible assets are being amortized on a straight-line basis over weighted-average periods ranging from one to fifteen years. Such assets are periodically evaluated as to the recoverability of their carrying value. Purchased software is being amortized using the straight-line method over periods ranging from one to three years.
Derivatives	Derivatives Derivatives are recognized as assets and liabilities on the consolidated balance sheet and measured at fair value. For exchange-traded contracts, fair value is based on quoted market prices. For non-exchange traded contracts, fair value is based on dealer quotes, pricing models, discounted cash flow methodologies or similar techniques for which the determination of fair value may require significant management judgment or estimation.
Mortgage Servicing Rights	Mortgage Servicing Rights Mortgage servicing assets are recognized separately when rights are acquired through purchase or through sale of financial assets. Under the servicing assets and liabilities accounting guidance (ASC 806-50), servicing rights from the sale or securitization of loans originated by the Company are initially measured at fair value at the date of transfer. The Company subsequently measures each class of servicing asset using the amortization method. Under the amortization method, servicing rights are amortized in proportion to and over the period of estimated net servicing income. The amortized assets are assessed for impairment based on fair value at each reporting date. Fair value is based on market prices for comparable mortgage servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost of service, the discount rate, the custodial earning rate, an inflation rate, ancillary income, prepayment speeds and default rates and losses. These variables change from quarter to quarter as market conditions and projected interest rates change, and may have an adverse impact on the value of the mortgage servicing right and may result in a reduction to noninterest income. Each class of separately recognized servicing assets subsequently measured using the amortization method is evaluated and measured for impairment. Impairment is determined by stratifying rights into tranches based on predominant characteristics, such as interest rate, loan type and investor type. Impairment is recognized through a valuation allowance for an individual tranche, to the extent that fair value is less than the carrying amount of the servicing assets for that tranche. The valuation allowance is adjusted to reflect changes in the measurement of impairment after the initial measurement of impairment. Changes in valuation allowances are reported with “Mortgage Loan Servicing Fees, net” on the income statement. Fair value in excess of the carrying amount of servicing assets for that stratum is not recognized. Servicing fee income is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal or a fixed amount per loan and are recorded as income when earned. The amortization of mortgage servicing rights is netted against loan servicing fee income.
Share-Based Employee Compensation Plan	Share-Based Employee Compensation Plan At December 31, 2017 and 2016, the Company had a share-based employee compensation plan, which is described more fully in Note 17 to the Consolidated Financial Statements.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of financial assets are accounted for as sales, when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company – put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before the maturity or the ability to unilaterally cause the holder to return specific assets.
Income Taxes	Income Taxes The Company accounts for income taxes in accordance with income tax accounting guidance (ASC 740, Income Taxes). The income tax accounting guidance results in two components of income tax expense: current and deferred. Current income tax expense reflects taxes to be paid or refunded for the current period by applying the provisions of the enacted tax law to the taxable income or excess of deductions over revenues. The Company determines deferred income taxes using the liability (or balance sheet) method. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax bases of assets and liabilities, and enacted changes in tax rates and laws are recognized in the period in which they occur. Deferred income tax expense results from changes in deferred tax assets and liabilities between periods. Deferred tax assets are reduced by a valuation allowance if, based on the weight of evidence available, it is more likely than not that some portion or all of a deferred tax asset will not be realized. Uncertain tax positions are recognized if it is more likely than not, based on the technical merits, that the tax position will be realized or sustained upon examination. The term more likely than not means a likelihood of more than 50 percent; the term “upon examination” also includes resolution of the related appeals or litigation processes, if any. A tax position that meets the more-likely-than-not recognition threshold is initially and subsequently measured as the largest amount of tax benefit that has a greater than 50 percent likelihood of being realized upon settlement with a taxing authority that has full knowledge of all relevant information. The determination of whether or not a tax position has met the more-likely-than-not recognition threshold considers the facts, circumstances and information available at the reporting date and is subject to management’s judgment. The Company recognizes interest and penalties on income taxes as a component of income tax expense. The Company files consolidated income tax returns with its subsidiaries. With a few exceptions, the Company is no longer subject to U.S. Federal, State and Local examinations by tax authorities for the years before 2014. As of December 31, 2017, the Company had no uncertain income tax positions. The Company uses the specific identification (or portfolio) method for reclassifying material stranded tax effects in accumulated other consolidated income (AOCI) to earnings. The Company elected to apply the provisions of ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. As a result, the Company reclassified $0.02 million from AOCI to retained earnings.
Treasury Shares	Treasury Shares Treasury stock is stated at cost. Cost is determined by the weighted-average cost method.
Earnings Per Share	Earnings Per Share Earnings per common share is computed using the two-class method. Basic earnings per share represent income available to common shareholders divided by the weighted-average number of common shares outstanding during each period. Diluted earnings per share reflect additional potential common shares and convertible preferred shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustment to income that would result from the assumed issuance. Potential common shares that may be issued by the Company relate solely to outstanding stock options which are determined using the treasury stock method and convertible preferred shares which are determined using the converted method. Treasury stock shares are not deemed outstanding for earnings per share calculations.
Comprehensive Income	Comprehensive Income Comprehensive income consists of net income and other comprehensive income, net of applicable income taxes. Other comprehensive income includes unrealized appreciation (depreciation) on available-for-sale securities, and unrealized and realized gains and losses in derivative financial instruments that qualify for hedge accounting. Accumulated other comprehensive income consists solely of the cumulative unrealized gains and losses on available-for-sale securities net of income tax.
New and applicable accounting pronouncements	New and applicable accounting pronouncements: Accounting Standards Update (ASU) No. 2018-02: Reclassifications of Certain tax Effects from Accumulated Other Comprehensive Income (Topic 220) In February of 2018, the FASB issued guidance that requires a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 ASU No. 2017-12: Derivatives and Hedging (Topic 815) This ASU better aligns an entity’s risk management activities and financial reporting for hedging relationships through changes to both the designation and measurement guidance for qualifying hedging relationships and the presentation of hedge results. The amendments in this ASU are effective for reporting periods beginning after December 15, 2018, and management does not believe the changes will have a material effect on the Company’s consolidated financial statements. ASU No. 2017-04: Intangibles – Goodwill and Other (Topic 350) This ASU simplifies the test for goodwill impairment. Specifically, these amendments eliminate Step 2 from the goodwill impairment test, and also eliminate the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. The amendments in this ASU are effective for annual goodwill impairment tests in fiscal years beginning after December 15, 2019, and management does not believe the changes will have a material effect on the Company’s accounting and disclosures. ASU No. 2016-13: Financial Instruments – Credit Losses (Topic 326) This ASU replaces the current GAAP incurred impairment methodology regarding credit losses 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 in this update affect an entity to varying degrees depending on the credit quality of the assets held by the entity, their duration, and how the entity applies current GAAP. The amendments in this ASU are effective for reporting periods beginning after December 15, 2019, and management will need further study to determine the impact on the Company’s consolidated financial statements. The Company implemented a process to track required data by utilizing accounting software in preparation for compliance. The adoption of ASU 2016-13 is likely to result in an increase in the allowance for loan losses as a result of changing from an “incurred loss” model, which encompasses allowances for current known and inherent losses within the portfolio, to an “expected loss” model, which encompasses allowances for losses expected to be incurred over the life of the portfolio. Furthermore, ASU 2016-13 will necessitate that we establish an allowance for expected credit losses on debt securities. While we are currently unable to reasonably estimate the impact of adopting ASU 2016-13, we expect that the impact of adoption will be significantly influenced by the composition, characteristics and quality of our loan and securities portfolios as well as the prevailing economic conditions and forecasts as of the adoption date. We anticipate being fully prepared for implementation by December 15, 2019. ASU No. 2016-09: Stock Compensation (Topic 718) This ASU affects all entities that issue share-based payment awards to their employees. The update is intended to simplify the accounting for these transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The Company adopted the amendments in this ASU, and management has determined that the impact on the Company’s consolidated financial statements is immaterial. ASU No. 2014-09: Revenue from Contracts with Customers (Topic 606) This ASU affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets unless those contracts are within the scope of other standards. The core principle is that an entity should recognize revenue in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Our revenue is comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014-09, and noninterest income. We have completed our evaluation of the impact of ASU 2014-09 on components of our noninterest income and have not found any significant changes to our methodology of recognizing revenue. As required by ASU 2014-09, we will adopt the standard in the first quarter of 2018 and, at the time of this filing, we do not anticipate recording a cumulative effect adjustment to opening retained earnings because the adjustment was determined to be insignificant. We will include newly applicable revenue disclosures in our Form 10-Q for the quarter ended March 31, 2018.
