Accounting Policies [Abstract]
Business Description and Basis of Presentation [Text Block]	Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and in accordance with the instructions to Form 10-Q and Rule 8-03 of Regulation S-X. Accordingly, they do not include all of the disclosures required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, all adjustments necessary for a fair presentation of the results of operations for the interim periods have been made. Such adjustments were normal and recurring in nature. The results of operations for the three months ended March 31, 2018 do not necessarily reflect the results that may be expected for the entire fiscal year ending December 31, 2018 or any other interim period. The consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes for the year ended December 31, 2017, which are included in Farmers and Merchants Bancshares, Inc.’s Annual Report on Form 10-K. In January 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” The amendments in ASU 2016-01, among other things: (i) requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; (ii) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables); and (iii) eliminates the requirement to disclose the fair value of financial instruments measured at amortized cost. The amendments within this ASU are effective for fiscal years beginning after December 15, 2017, and for interim periods within those fiscal years. The new guidance permits early adoption of the provision that exempts private companies and not-for-profit organizations from having to disclose at fair value information about financial instruments measured at amortized cost. The Company adopted the provisions of ASU 2016-01, effective January 1, 2018, by recording a $ 10,416 In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 841).” Among other things, in the amendments in ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (i) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early application is permitted upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company expects that the impact that ASU 2016-02 will be to increase assets and liabilities equally by approximately $ 1,400,000 In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses”. The ASU sets forth a “current expected credit loss” (CECL) model which requires the Company to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions, and reasonable supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost and applies to some off-balance sheet credit exposures. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is currently assessing the impact of the adoption of this ASU on its consolidated financial statements and has begun developing an implementation plan. In March 2017, the FASB issued ASU 2017-08, “Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20) – Premium Amortization on Purchased Callable Debt Securities.” ASU 2017-08 shortens the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. ASU 2017-08 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 and is not expected to have a significant impact on our financial statements.

As of March 31, 2018 and December 31, 2017, management did not have the intent to sell any of the securities before a recovery of cost. The unrealized losses are due to increases in market interest rates over the yields available at the time the underlying securities were purchased as well as other market conditions for each particular security based upon the structure and remaining principal balance. The fair values of the investment securities are expected to recover as the securities approach their maturity dates or repricing dates or if market yields for such investments decline. Based on the these factors, as of March 31, 2018 and December 31, 2017, management believes the unrealized losses detailed in the table above are temporary and, accordingly, none of these unrealized losses have been recognized in the Company’s consolidated statement of income.

These concessions typically result from the Company’s loss mitigation activities and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance, or other actions. Certain TDRs are classified as nonperforming at the time of restructure and may only be returned to performing status after considering the borrower’s sustained repayment performance for a reasonable period, generally six months. At March 31, 2018, the Company had one $ 2,150,998 At December 31, 2017, the Company had three commercial real estate loans totaling $2,937,439 classified as TDRs. Two loans totaling $774,274 were restructured as TDRs during 2017 and were paid off during the quarter ended March 31, 2018. All are included in impaired loans above. The remaining loan is paying as agreed. There have been no charge-offs or allowances associated with these three loans. As part of our portfolio risk management, the Company assigns a risk grade to each loan. The factors used to determine the grade are the payment history of the loan and the borrower, the value of the collateral and net worth of the guarantor, and cash flow projections of the borrower. Excellent, Above Average, Average and Acceptable grades are assigned to loans with limited or no delinquent payments and more than sufficient collateral and/or cash flow. A description of the general characteristics of loans characterized as watch list or classified is as follows: Pass/Watch Loans graded as Pass/Watch are secured by generally acceptable assets which reflect above-average risk. The loans warrant closer scrutiny by management than is routine, due to circumstances affecting the borrower, the borrower’s industry, or the overall economic environment. Borrowers may reflect weaknesses such as inconsistent or weak earnings, break even or moderately deficit cash flow, thin liquidity, minimal capacity to increase leverage, or volatile market fundamentals or other industry risks. Such loans are typically secured by acceptable collateral, at or near appropriate margins, with realizable liquidation values. Special Mention A special mention loan has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Company’s credit position at some future date. Special mention loans are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification. Borrowers may exhibit poor liquidity and leverage positions resulting from generally negative cash flow or negative trends in earnings. Access to alternative financing may be limited to finance companies for business borrowers and may be unavailable for commercial real estate borrowers. Substandard A substandard loan is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Substandard loans have a well-defined weakness, or weaknesses, that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Borrowers may exhibit recent or unexpected unprofitable operations, an inadequate debt service coverage ratio, or marginal liquidity and capitalization. These loans require more intense supervision by Company management. Doubtful A doubtful loan has all the weaknesses inherent as a substandard loan with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loans by credit grade, segregated by loan type, are as follows: Above Pass Special March 31, 2018 Excellent average Average Acceptable watch mention Substandard Doubtful Total Real estate: Commercial $ - $ 5,889,617 $ 115,158,666 $ 88,862,495 $ 15,228,108 $ 7,550,301 $ 2,433,209 $ 2,245,743 $ 237,368,139 Construction and land development - 1,038,353 6,979,511 7,231,069 3,998,162 - - - 19,247,095 Residential 41,435 1,190,516 31,896,681 21,929,125 3,378,805 - 647,091 - 59,083,653 Commercial 1,565,870 120,006 12,840,759 9,320,008 149,514 - - - 23,996,157 Consumer - 93,506 329,882 64,046 - - 2,340 30,994 520,768 $ 1,607,305 $ 8,331,998 $ 167,205,499 $ 127,406,743 $ 22,754,589 $ 7,550,301 $ 3,082,640 $ 2,276,737 $ 340,215,812 Above Pass Special December 31, 2017 Excellent average Average Acceptable watch mention Substandard Doubtful Total Real estate: Commercial $ - $ 6,115,925 $ 127,639,361 $ 79,619,726 $ 9,041,882 $ 5,391,589 $ 3,972,348 $ 2,245,743 $ 234,026,574 Construction and land development - 173,633 9,288,372 4,978,964 3,719,397 - - - 18,160,366 Residential 53,948 1,260,128 35,254,016 18,659,174 3,363,570 - 650,580 - 59,241,416 Commercial 1,581,878 121,919 16,225,350 5,545,562 138,834 - - - 23,613,543 Consumer 5,210 96,484 351,093 70,171 - - 2,640 28,419 554,017 $ 1,641,036 $ 7,768,089 $ 188,758,192 $ 108,873,597 $ 16,263,683 $ 5,391,589 $ 4,625,568 $ 2,274,162 $ 335,595,916 The Company’s allowance for loan losses is based on management’s evaluation of the risks inherent in the Company’s The following table details activity in the allowance for loan losses by portfolio for the three months ended March 31, 2018 and 2017, and the year ended December 31, 2017.

Capital Standards

Capital Standards	3 Months Ended

Banking and Thrift [Abstract]
Regulatory Capital Requirements under Banking Regulations [Text Block]	Capital Standards The Company and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possible additional, discretionary actions by the regulators that, if undertaken, could have a direct material effect on our financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, we must meet specific capital guidelines that involve quantitative measures of our assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. Our capital amounts and classifications are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. The Basel III Capital Rules became effective for the Bank on January 1, 2015 (subject to a phase-in period for certain provisions). Quantitative measures established by the Basel III Capital Rules to ensure capital adequacy require the maintenance of minimum amounts and ratios (set forth in the table below) of Common Equity Tier 1 capital, Tier 1 capital, and Total capital (as defined in the regulations) to risk-weighted assets (as defined), and of Tier 1 capital to adjusted quarterly average assets (as defined). In connection with the adoption of the Basel III Capital Rules, the Bank elected to opt-out of the requirement to include accumulated other comprehensive income in Common Equity Tier 1 capital. Common Equity Tier 1 capital for the Bank is reduced by goodwill and other intangible assets, net of associated deferred tax liabilities and subject to transition provisions. Under the revised prompt corrective action requirements, as of January 1, 2015, insured depository institutions are required to meet the following in order to qualify as “well capitalized”: (i) a common equity Tier 1 risk-based capital ratio of 6.5%; (ii) a Tier 1 risk-based capital ratio of 8%; (iii) a total risk-based capital ratio of 10%; and (iv) a Tier 1 leverage ratio of 5%. Management believes that, as of March 31, 2018, the Bank met all capital adequacy requirements under the Basel III Capital Rules on a fully phased-in basis as if such requirements were fully in effect. The implementation of the capital conservation buffer began on January 1, 2016, at the 0.625% level and will be phased in over a four-year period (increasing by that amount on each subsequent January 1, until it reaches 2.5% on January 1, 2019). The Basel III Capital Rules also provide for a “countercyclical capital buffer” that is applicable to only certain covered institutions and does not have current applicability to the Bank. Management believes that, as of March 31, 2018, the Bank met all capital adequacy requirements under the Basel III Capital Rules on a fully phased-in basis as if such requirements were currently in effect. The aforementioned capital conservation buffer is designed to absorb losses during periods of economic stress. Banking institutions with a ratio of Common Equity Tier 1 capital to risk-weighted assets above the minimum but below the conservation buffer (or below the combined capital conservation buffer and countercyclical capital buffer, when the latter is applied) will face constraints on dividends, equity repurchases, and compensation based on the amount of the shortfall. The following table presents actual and required capital ratios as of March 31, 2018 and December 31, 2017, for the Bank under the Basel III Capital Rules. The minimum required capital amounts presented include the minimum required capital levels as of March 31, 2018 and December 31, 2017 based on the phase-in provisions of the Basel III Capital Rules. Capital levels required to be considered well capitalized are based upon prompt corrective action regulations, as amended to reflect the changes under the Basel III Capital Rules. As of March 31, 2018, the most recent notification from the FDIC has categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized the Bank must maintain ratios as set forth in the table. There have been no conditions or events since that notification that management believes have changed the Bank’s category. Capital ratios of the Company are substantially the same as the Bank’s.

Fair Value Disclosures [Abstract]
Fair Value Disclosures [Text Block]	Fair Value Accounting standards define fair value as the price that would be received upon the sale of an asset or paid upon the transfer of a liability in an orderly transaction between market participants. The price in the principal market used to measure the fair value of the asset or liability is not adjusted for transaction costs. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact and (iv) willing to transact. The standards require the use of valuation techniques that are consistent with the market approach, the income approach and/or the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement cost). Valuation techniques should be consistently applied. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. The standards establish a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: ⋅ Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. ⋅ Level 2: Significant other observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, and other inputs that are observable or can be corroborated by observable market data. ⋅ Level 3: Significant unobservable inputs that reflect the Company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. The Company uses the following methods and significant assumptions to estimate the fair values of the following assets: ⋅ Securities available for sale: The fair values of securities available for sale are determined by obtaining quoted prices from a nationally recognized securities pricing agent. If quoted market prices are not available, fair value is determined using quoted market prices for similar securities. ⋅ Other real estate owned (“OREO”): Nonrecurring fair value adjustments to OREO reflect full or partial write-downs that are based on the OREO’s observable market price or current appraised value of the real estate. Since the market for OREO is not active, OREO subjected to nonrecurring fair value adjustments based on the current appraised value of the real estate are classified as Level 3. The appraised value is obtained annually from an independent third party appraiser and is reduced by expected sales costs, which has historically been 10% of the appraised value. ⋅ Impaired loans: Nonrecurring fair value adjustments to impaired loans reflect full or partial write-downs and reserves that are based on the impaired loan’s observable market price or current appraised value of the collateral. Since the market for impaired loans is not active, such loans subjected to nonrecurring fair value adjustments based on the current appraised value of the collateral are classified as Level 3. The appraised value is obtained annually from an independent third party appraiser and is reduced by expected sales costs, which has historically been 10% of the appraised value.

Beginning in the first quarter 2018 the fair value of loans were determined using an exit price methodology as prescribed by ASU 2016-01, which became effective in the first quarter 2018. The exit price estimation of fair value is based on the present value of the expected cash flows. The projected cash flows are based on the contractual terms of the loans, adjusted for prepayments and use of a discount rate based on the relative risk of the cash flows, taking into account the loan type, maturity of the loan, liquidity risk, servicing costs, and a required return on debt and capital (Level 3). In addition, an incremental liquidity discount is applied to certain loans, using historical sales of loans during periods of similar economic conditions as a benchmark. In comparison, loan fair values as of December 31, 2017 were estimated based on an entrance price methodology. As a result the fair value adjustments as of March 31, 2018 and December 31, 2017 are not comparable. The fair values of interest-bearing checking, savings, and money market deposit accounts are equal to their carrying amounts. The fair values of fixed-maturity time deposits are estimated based on interest rates currently offered for deposits of similar remaining maturities. The fair value of credit commitments are considered to be the same as the contractual amounts, and are not included in the table above. These commitments generate fees that approximate those currently charged to originate similar commitments.

Accounting Policies [Abstract]
New Accounting Pronouncements, Policy [Policy Text Block]	Recent Accounting Pronouncements In January 2016, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2016-01, “Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.” The amendments in ASU 2016-01, among other things: (i) requires equity investments (except those accounted for under the equity method of accounting, or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income; (ii) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset (i.e., securities or loans and receivables); and (iii) eliminates the requirement to disclose the fair value of financial instruments measured at amortized cost. The amendments within this ASU are effective for fiscal years beginning after December 15, 2017, and for interim periods within those fiscal years. The new guidance permits early adoption of the provision that exempts private companies and not-for-profit organizations from having to disclose at fair value information about financial instruments measured at amortized cost. The Company adopted the provisions of ASU 2016-01, effective January 1, 2018, by recording a $ 10,416 In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 841).” Among other things, in the amendments in ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases) at the commencement date: (i) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Certain targeted improvements were made to align, where necessary, lessor accounting with the lessee accounting model and Topic 606, Revenue from Contracts with Customers. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early application is permitted upon issuance. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. The Company expects that the impact that ASU 2016-02 will be to increase assets and liabilities equally by approximately $ 1,400,000 In June 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses”. The ASU sets forth a “current expected credit loss” (CECL) model which requires the Company to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions, and reasonable supportable forecasts. This replaces the existing incurred loss model and is applicable to the measurement of credit losses on financial assets measured at amortized cost and applies to some off-balance sheet credit exposures. This ASU is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company is currently assessing the impact of the adoption of this ASU on its consolidated financial statements and has begun developing an implementation plan. In March 2017, the FASB issued ASU 2017-08, “Receivables-Nonrefundable Fees and Other Costs (Subtopic 310-20) – Premium Amortization on Purchased Callable Debt Securities.” ASU 2017-08 shortens the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. ASU 2017-08 will be effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018 and is not expected to have a significant impact on our financial statements.
