Significant Accounting Policies	'
	1	Significant Accounting Policies
	The consolidated financial statements for the three months ended March 31, 2014 and 2013 are unaudited. In the opinion of the management of Ames National Corporation (the "Company"), these financial statements reflect all adjustments, consisting only of normal recurring accruals, necessary to present fairly these consolidated financial statements. The results of operations for the interim periods are not necessarily indicative of results which may be expected for an entire year. Certain information and footnote disclosures normally included in complete financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been omitted in accordance with the requirements for interim financial statements. The interim financial statements and notes thereto should be read in conjunction with the year-end audited financial statements contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2013 (the “Annual Report”). The consolidated financial statements include the accounts of the Company and its wholly-owned banking subsidiaries (the “Banks”). All significant intercompany balances and transactions have been eliminated in consolidation.
	Goodwill:  Goodwill represents the excess of cost over the fair value of net assets acquired.  Goodwill resulting from acquisitions is not amortized, but is tested for impairment annually or whenever events change and circumstances indicate that it is more likely than not that an impairment loss has occurred.  Goodwill is tested for impairment using a two-step process that begins with an estimation of the fair value of a reporting unit.  The second step, if necessary, measures the amount of impairment, if any.
	Significant judgment is applied when goodwill is assessed for impairment.  This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions and selecting an appropriate control premium.  At March 31, 2014, Company management has performed a goodwill impairment analysis and determined goodwill was not impaired.
	New Accounting Pronouncements:  In January 2014, the Financial Accounting Standards Board issued Accounting Standards Update No. 2014-04, Receivables—Troubled Debt Restructuring by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans Upon Foreclosure. The update clarifies when an in substance foreclosure occurs, that is, when a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan. This is the point when the consumer mortgage loan should be derecognized and the real property recognized. For public companies, this update will be effective for interim and annual periods beginning after December 31, 2014 and early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.

Fair Value Measurements	'
	5	Fair Value Measurements
	Assets and liabilities carried at fair value are required to be classified and disclosed according to the process for determining fair value.  There are three levels of determining fair value.
	Level 1:  Inputs to the valuation methodology are quoted prices, unadjusted, for identical assets or liabilities in active markets.  A quoted price in an active market provides the most reliable evidence of fair value and shall be used to measure fair value whenever available.
	Level 2:  Inputs to the valuation methodology include: quoted prices for similar assets or liabilities in active markets; quoted process for identical or similar assets or liabilities in markets that are not active; inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatility, prepayment speeds, credit risk); or inputs derived principally from or can be corroborated by observable market data by correlation or other means.
	Level 3:  Inputs to the valuation methodology are unobservable and significant to the fair value measurement.  Level 3 assets and liabilities include financial instruments whose value is determined using discounted cash flow methodologies, as well as instruments for which the determination of fair value requires significant management judgment or estimation.
	The following table presents the balances of assets measured at fair value on a recurring basis by level as of March 31, 2014 and December 31, 2013.

	Level 1 securities include those traded on an active exchange, such as the New York Stock Exchange, as well as U.S. Treasury securities that are traded by dealers or brokers in active over-the-counter markets. Other securities available-for-sale are reported at fair value utilizing Level 2 inputs. For these securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the security’s terms and conditions, among other things.
	Certain assets are measured at fair value on a nonrecurring basis; that is, they are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment).  The following table presents the assets carried on the balance sheet (after specific reserves) by caption and by level with the valuation hierarchy as of March 31, 2014 and December 31, 2013.

	Loans Receivable:  Loans in the tables above consist of impaired credits held for investment.  In accordance with the loan impairment guidance, impairment was measured based on the fair value of collateral less estimated selling costs for collateral dependent loans.  Fair value for impaired loans is based upon appraised values of collateral adjusted for trends observed in the market.  A valuation allowance was recorded for the excess of the loan’s recorded investment over the amounts determined by the collateral value method.  This valuation is a component of the allowance for loan losses.  The Company considers these fair value measurements as level 3.
	Other Real Estate Owned:  Other real estate owned in the table above consists of real estate obtained through foreclosure.  Other real estate owned is recorded at fair value less estimated selling costs, at the date of transfer.  Subsequent to the transfer, other real estate owned is carried at the lower of cost or fair value, less estimated selling costs.  The carrying value of other real estate owned is not re-measured to fair value on a recurring basis but is subject to fair value adjustments when the carrying value exceeds the fair value less estimated selling costs.  Management uses appraised values and adjusts for trends observed in the market and for disposition costs in determining the value of other real estate owned. A valuation allowance was recorded for the excess of the asset’s recorded investment over the amount determined by the fair value, less estimated selling costs.  This valuation allowance is a component of the allowance for other real estate owned.  The valuation allowance was $4,644,000 as of March 31, 2014 and December 31, 2013.  The Company considers these fair values level 3.
	The significant inputs used in the fair value measurements for Level 3 assets measured at fair value on a nonrecurring basis as of March 31, 2014 and December 31, 2013 are as follows:
			2014
			Fair Value			Valuation		Range
						Techniques	Range of Unobservable Inputs	(Average)
	Impaired Loans		$	752,000		Evaluation of collateral	Estimation of value	NM*
	Other real estate owned		$	8,880,000		Appraisal	Appraisal adjustment	6%-10% (8%)

	Other real estate owned		$	8,861,000		Appraisal	Appraisal adjustment	6%-10% (8%)
	* Not Meaningful. Evaluations of the underlying assets are completed for each impaired loan with a specific reserve. The types of collateral vary widely and could include accounts receivables, inventory, a variety of equipment and real estate. Collateral evaluations are reviewed and discounted as appropriate based on knowledge of the specific type of collateral. In the case of real estate, an independent appraisal may be obtained. Types of discounts considered included aging of receivables, condition of the collateral, potential market for the collateral and estimated disposal costs. These discounts will vary from loan to loan, thus providing a range would not be meaningful.
	Accounting principles generally accepted in the United State of America (GAAP) requires disclosure of the fair value of financial assets and financial liabilities, including those that are not measured and reported at fair value on a recurring basis or nonrecurring basis.  The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value on a recurring or nonrecurring basis are discussed above.  The methodologies for other financial assets and financial liabilities are discussed below.
	Fair value of financial instruments:
	Disclosure of fair value information about financial instruments, for which it is practicable to estimate that value, is required whether or not recognized in the consolidated balance sheets. In cases in which quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimate of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases could not be realized in immediate settlement of the instruments. Certain financial instruments with a fair value that is not practicable to estimate and all non-financial instruments are excluded from the disclosure requirements. Accordingly, the aggregate fair value amounts presented do not necessarily represent the underlying value of the Company.
	The following disclosures represent financial instruments in which the ending balances at March 31, 2014 and December 31, 2013 are not carried at fair value in their entirety on the consolidated balance sheets.
	Cash and due from banks and interest bearing deposits in financial institutions:  The recorded amount of these assets approximates fair value.
	Securities available-for-sale:  Fair value measurement is based upon quoted prices, if available.  If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the securities credit rating, prepayment assumptions and other factors such as credit loss assumptions.
	Loans held for sale:  The fair value of loans held for sale is based on prevailing market prices.
	Loans receivable:  The fair value of loans is calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates, which reflect the credit and interest rate risk inherent in the loan.  The estimate of maturity is based on the historical experience, with repayments for each loan classification modified, as required, by an estimate of the effect of current economic and lending conditions.  The effect of nonperforming loans is considered in assessing the credit risk inherent in the fair value estimate.
	Deposit liabilities:  Fair values of deposits with no stated maturity, such as noninterest-bearing demand deposits, savings and NOW accounts, and money market accounts, are equal to the amount payable on demand as of the respective balance sheet date.  Fair values of certificates of deposit are based on the discounted value of contractual cash flows.  The discount rate is estimated using the rates currently offered for deposits of similar remaining maturities.  The fair value estimates do not include the benefit that results from the low-cost funding provided by the deposit liabilities compared to the cost of borrowing funds in the market.
	Securities sold under agreements to repurchase and federal funds purchased:  The carrying amounts of securities sold under agreements to repurchase and federal funds purchased approximate fair value because of the generally short-term nature of the instruments.
	FHLB advances and other long-term borrowings:  Fair values of FHLB advances and other long-term borrowings are estimated using discounted cash flow analysis based on interest rates currently being offered with similar terms.
	Accrued income receivable and accrued interest payable:  The carrying amounts of accrued income receivable and accrued interest payable approximate fair value.
	Commitments to extend credit and standby letters of credit:  The fair values of commitments to extend credit and standby letters of credit are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreement and credit worthiness of the counterparties.  The carry value and fair value of the commitments to extend credit and standby letters of credit are not considered significant.
	Limitations:  Fair value estimates are made at a specific point in time, based on relevant market information and information about the financial instrument.  Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors.  These estimates are subjective in nature and involve uncertainties and matters of significant judgment and, therefore, cannot be determined with precision.  Changes in assumptions could significantly affect the estimates.
	The estimated fair values of the Company’s financial instruments as described above were as follows:

	Gross unrealized losses on debt securities totaled $6,048,793 as of March 31, 2014.  These unrealized losses are generally due to changes in interest rates or general market conditions.  In analyzing an issuer’s financial condition, management considers whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and industry analysts’ reports. Management concluded that the gross unrealized losses on debt securities were temporary.  Due to potential changes in conditions, it is at least reasonably possible that changes in fair values and management’s assessments will occur in the near term and that such changes could materially affect the amounts reported in the Company’s financial statements.

	A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payment of principal and 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.  The Company will apply its normal loan review procedures to identify loans that should be evaluated for impairment.  The following is a recap of impaired loans, on a disaggregated basis, at March 31, 2014 and December 31, 2013: (in thousands)

	Management evaluated subsequent events through the date the financial statements were issued.  On April 30, 2014, First National Bank, Ames, Iowa, a 100% owned subsidiary of Ames National Corporation, entered into a purchase and assumption agreement with another financial institution to purchase substantially all of the assets of the other institution, including loans, and assume substantially all of the liabilities of the other institution, including deposits.  At closing, First National Bank expects to provide the seller with a payment of approximately $4,700,000, adjusted for certain items at closing.  The transaction is expected to close in the third quarter of 2014, subject to regulatory approval and other customary closing conditions.  There were no other significant events or transactions occurring after March 31, 2014, but prior to May 8, 2014, that provided additional evidence about conditions that existed at March 31, 2014.  There were no other significant events or transactions that provided evidence about conditions that did not exist at March 31, 2014.

Significant Accounting Policies [Abstract]	'
Consolidation	'
	The consolidated financial statements for the three months ended March 31, 2014 and 2013 are unaudited. In the opinion of the management of Ames National Corporation (the "Company"), these financial statements reflect all adjustments, consisting only of normal recurring accruals, necessary to present fairly these consolidated financial statements. The results of operations for the interim periods are not necessarily indicative of results which may be expected for an entire year. Certain information and footnote disclosures normally included in complete financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been omitted in accordance with the requirements for interim financial statements. The interim financial statements and notes thereto should be read in conjunction with the year-end audited financial statements contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2013 (the “Annual Report”). The consolidated financial statements include the accounts of the Company and its wholly-owned banking subsidiaries (the “Banks”). All significant intercompany balances and transactions have been eliminated in consolidation.
Goodwill	'
	Goodwill:  Goodwill represents the excess of cost over the fair value of net assets acquired.  Goodwill resulting from acquisitions is not amortized, but is tested for impairment annually or whenever events change and circumstances indicate that it is more likely than not that an impairment loss has occurred.  Goodwill is tested for impairment using a two-step process that begins with an estimation of the fair value of a reporting unit.  The second step, if necessary, measures the amount of impairment, if any.
	Significant judgment is applied when goodwill is assessed for impairment.  This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions and selecting an appropriate control premium.  At March 31, 2014, Company management has performed a goodwill impairment analysis and determined goodwill was not impaired.
New Accounting Pronouncements	'
	New Accounting Pronouncements:  In January 2014, the Financial Accounting Standards Board issued Accounting Standards Update No. 2014-04, Receivables—Troubled Debt Restructuring by Creditors (Subtopic 310-40): Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans Upon Foreclosure. The update clarifies when an in substance foreclosure occurs, that is, when a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan. This is the point when the consumer mortgage loan should be derecognized and the real property recognized. For public companies, this update will be effective for interim and annual periods beginning after December 31, 2014 and early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company's consolidated financial statements.

	Other real estate owned		$	8,861,000		Appraisal	Appraisal adjustment	6%-10% (8%)
	* Not Meaningful. Evaluations of the underlying assets are completed for each impaired loan with a specific reserve. The types of collateral vary widely and could include accounts receivables, inventory, a variety of equipment and real estate. Collateral evaluations are reviewed and discounted as appropriate based on knowledge of the specific type of collateral. In the case of real estate, an independent appraisal may be obtained. Types of discounts considered included aging of receivables, condition of the collateral, potential market for the collateral and estimated disposal costs. These discounts will vary from loan to loan, thus providing a range would not be meaningful.

[1]	Not Meaningful. Evaluations of the underlying assets are completed for each impaired loan with a specific reserve. The types of collateral vary widely and could include accounts receivables, inventory, a variety of equipment and real estate. Collateral evaluations are reviewed and discounted as appropriate based on knowledge of the specific type of collateral. In the case of real estate, an independent appraisal may be obtained. Types of discounts considered included aging of receivables, condition of the collateral, potential market for the collateral and estimated disposal costs. These discounts will vary from loan to loan, thus providing a range would not be meaningful.
