Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	BASIS OF PRESENTATION: The accompanying consolidated financial statements include the accounts of Ohio Valley Banc Corp. (“Ohio Valley”) and its wholly-owned subsidiaries, The Ohio Valley Bank Company (the “Bank”), Loan Central, Inc. (“Loan Central”), a consumer finance company, and Ohio Valley Financial Services Agency, LLC (“Ohio Valley Financial Services”), an insurance agency. Ohio Valley and its subsidiaries are collectively referred to as the “Company”. All material intercompany accounts and transactions have been eliminated in consolidation. These interim financial statements are prepared by the Company without audit and reflect all adjustments of a normal recurring nature which, in the opinion of management, are necessary to present fairly the consolidated financial position of the Company at September 30, 2013, and its results of operations and cash flows for the periods presented. The results of operations for the nine months ended September 30, 2013 are not necessarily indicative of the operating results to be anticipated for the full fiscal year ending December 31, 2013. The accompanying consolidated financial statements do not purport to contain all the necessary financial disclosures required by U.S. generally accepted accounting principles (“US GAAP”) that might otherwise be necessary in the circumstances. The Annual Report of the Company for the year ended December 31, 2012 contains consolidated financial statements and related notes which should be read in conjunction with the accompanying consolidated financial statements. The consolidated financial statements for 2012 have been reclassified to conform to the presentation for 2013. These reclassifications had no effect on the net results of operations or shareholders’ equity.
Use of Estimates, Policy [Policy Text Block]	USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS: The accounting and reporting policies followed by the Company conform to US GAAP. The preparation of financial statements in conformity with US GAAP 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. Actual results could differ from those estimates. Areas involving the use of management’s estimates and assumptions that are more susceptible to change in the near term involve the allowance for loan losses, mortgage servicing rights, deferred tax assets, the fair value of certain securities, the fair value of financial instruments and the determination and carrying value of impaired loans and other real estate owned.
Segment Reporting, Policy [Policy Text Block]	INDUSTRY SEGMENT INFORMATION: Internal financial information is primarily reported and aggregated in two lines of business, banking and consumer finance.
Earnings Per Share, Policy [Policy Text Block]	EARNINGS PER SHARE: Earnings per share are computed based on net income divided by the weighted average number of common shares outstanding during the period. The weighted average common shares outstanding were 4,062,204 and 4,029,439 for the three months ended September 30, 2013 and 2012, respectively. Weighted average common shares outstanding were 4,062,204 and 4,028,944 for the nine months ended September 30, 2013 and 2012, respectively. Ohio Valley had no dilutive effect and no potential common shares issuable under stock options or other agreements for any period presented.
New Accounting Pronouncements, Policy [Policy Text Block]	ADOPTION OF NEW ACCOUNTING PRONOUNCEMENTS: In February 2013, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update 2013-02, “Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” (ASU 2013-02). ASU 2013-02 requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under U.S. GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under U.S. GAAP that provide additional detail about these amounts. ASU 2013-02 is effective prospectively for reporting periods beginning after December 15, 2012. The effect of adopting ASU 2013-02 did not have a material effect on the Company’s financial statements. In July 2013, the FASB issued Accounting Standards Update 2013-10, “Derivatives and Hedging (Topic 815), Inclusion of the Fed Funds Effective Swap Rate (or Overnight Index Swap Rate) as a Benchmark Interest Rate for Hedge Accounting Purposes” (ASU 2013-10). ASU 2013-10 was issued to permit the Fed Funds Effective Swap Rate to be used as a U.S. benchmark interest rate for hedge accounting purposes under Topic 815, in addition to direct Treasury obligations of the U.S. Government and the London Interbank Offered Rate (LIBOR) swap rate. ASU 2013-10 is effective prospectively for qualifying new or redesignated hedging relationships entered into on or after July 17, 2013. The adoption of ASU 2013-10 did not have a material effect on the Company’s financial statements. In July 2013, the FASB issued Accounting Standards Update 2013-11, “Income Taxes (Topic 740), Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists” (ASU 2013-11). ASU 2013-11 was issued to clarify the financial presentation of unrecognized tax benefits in the instances described. ASU 2013-11 is effective for reporting periods beginning after December 15, 2013. The effect of adopting ASU 2013-11 is not expected to have a material effect on the Company’s financial statements.
