Basis of Presentation	'
	Note 1. Basis of Presentation
	Basis of presentation: The consolidated financial statements of Regional Management Corp. (the “Company,” “we,” “us,” and “our”) have been prepared in accordance with the instructions to the Quarterly Report on Form 10-Q adopted by the Securities and Exchange Commission (“SEC”) and generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information, and, accordingly, do not include all information and note disclosures required by GAAP for complete financial statements. The interim financial statements in this Quarterly Report on Form 10-Q have not been audited by an independent registered public accounting firm in accordance with standards of the Public Company Accounting Oversight Board (U.S.), but in the opinion of management include all adjustments, consisting only of normal recurring adjustments necessary for a fair presentation of the Company’s financial position, results of operations, and cash flows in accordance with GAAP. These consolidated financial statements should be read in conjunction with our current Annual Report on Form 10-K for the year ended December 31, 2013 and filed with the SEC.

Nature of Business and Significant Accounting Policies	'
	Note 2. Nature of Business and Significant Accounting Policies
	Nature of business: The Company was incorporated and began operations in 1987. The Company is engaged in the consumer finance business, offering small installment loans, large installment loans, automobile purchase loans, retail purchase loans, and related credit insurance. As of March 31, 2014, the Company operated offices in 281 locations in the states of Alabama (49 offices), Georgia (3 offices), North Carolina (29 offices), New Mexico (8 offices), Oklahoma (27 offices), South Carolina (70 offices), Tennessee (21 offices), and Texas (74 offices) under the names Regional Finance, RMC Financial Services, Anchor Finance, Superior Financial Services, First Community Credit, AutoCredit Source, RMC Retail, and Sun Finance. The Company opened 17 new offices during the three months ended March 31, 2014.
	Seasonality: Our loan volume and corresponding finance receivables follow seasonal trends. Demand for our loans is typically highest during the third and fourth quarter, largely due to customers borrowing money for back-to-school and holiday spending. Loan demand has generally been the lowest during the first quarter, largely due to the timing of income tax refunds. During the remainder of the year, we typically experience loan growth from general operations. In addition, we typically generate higher loan volumes in the second half of the year from our direct mail campaigns, which are timed to coincide with seasonal consumer demand. Consequently, we experience significant seasonal fluctuations in our operating results and cash needs.
	The following is a description of significant accounting policies used in preparing the financial statements.
	Principles of consolidation: The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The Company operates through a separate subsidiary in each state.
	The accounting and reporting policies of the Company are in accordance with GAAP and conform to general practices within the consumer finance industry.
	Use of estimates: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and disclosure of contingent assets and liabilities for the periods indicated in the financial statements. Actual results could differ from those estimates.
	Material estimates that are particularly susceptible to change relate to the determination of the allowance for credit losses, fair value of stock based compensation, the valuation of deferred tax assets and liabilities, and the allocation of the purchase price to assets acquired in business combinations.
	Reclassifications: Certain prior period amounts have been reclassified to conform to the current presentation. Such reclassifications had no impact on previously reported net income or stockholders’ equity.

Disclosure About Fair Value of Financial Instruments	'
	Note 6. Disclosure About Fair Value of Financial Instruments
	The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate fair value:
	Finance receivables: Finance receivables are originated at prevailing market rates. The Company’s finance receivable portfolio turns approximately 1.4 times per year. The portfolio turnover is calculated by dividing cash payments and renewals by the average finance receivables. Management believes that the carrying value approximates the fair value of its finance receivable portfolio.
	Repossessed assets: Repossessed assets are valued at the lower of the receivable balance on the finance receivable prior to repossession or estimated net realizable value. The Company estimates net realizable value at the projected cash value upon liquidation, less costs to sell the related collateral.
	Debt: The Company refinanced its senior revolving credit facility in January 2012, and further amended the senior revolving credit facility in July 2012, March 2013, May 2013, and November 2013. As a result of the refinancing, the Company believes that the fair value of this variable rate debt approximates its carrying value at March 31, 2014. The Company also considered its creditworthiness in its determination of fair value.
	The carrying amount and estimated fair values of the Company’s financial instruments summarized by level are as follows:
		March 31, 2014				December 31, 2013
		Carrying		Estimated		Carrying		Estimated
		Amount		Fair Value		Amount		Fair Value
	Assets
	Level 1 inputs
	Cash	$	6,265	$	6,265	$	4,121	$	4,121

	Level 3 inputs
	Net finance receivables		467,409		467,409		514,595		514,595
	Repossessed assets		806		806		548		548
	Liabilities
	Level 3 inputs
	Senior revolving credit facility		310,315		310,315		362,750		362,750
	Certain of the Company’s assets carried at fair value are classified and disclosed in one of the following three categories:
	Level 1 – Quoted market prices in active markets for identical assets or liabilities.
	Level 2 – Observable market-based inputs or unobservable inputs that are corroborated by market data.
	Level 3 – Unobservable inputs that are not corroborated by market data.
	In determining the appropriate levels, the Company performs an analysis of the assets and liabilities that are carried at fair value. At each reporting period, all assets and liabilities for which the fair value measurement is based on significant unobservable inputs are classified as Level 3.

Employee Benefit Plans	'
	Note 9. Employee Benefit Plans
	Paid time off policy: The Company modernized its Paid Time Off (“PTO”) policy effective February 1, 2014. The new policy terms are more consistent with industry practices on the amount of PTO, eligible service requirements, cashout policy, and the use of partial PTO days. The policy change had accounting implications. Under the legacy policy, employees earned PTO in one year and then were able to use the PTO in the following year. That type of policy created a PTO liability under compensated absences accounting literature. Under the new policy, PTO is earned and used in the same calendar year, eliminating a PTO liability at the end of each year (with the exception of carryover PTO granted in extenuating circumstances). In the transition to the new policy, employees were given the opportunity to forfeit earned and unused PTO days under the legacy policy in exchange for additional PTO days and other benefits under the new policy or to remain on the old policy. As a result, effective January 31, 2014, based upon employee elections in January 2014, the PTO liability for certain employees was eliminated, and beginning February 1, 2014, such employees began accruing PTO under the new policy. The effect of the policy change was reflected in the period the change was implemented. Thus, in the first quarter of 2014, this change in policy resulted in a reversal of $1.4 million of personnel expense.
	Health insurance plan: As of May 1, 2014, the Company will no longer offer a minimum essential coverage insurance plan for newly-hired hourly employees and hourly employees not participating in the Company’s major medical health plan.
	Stock compensation plans: The Company has the 2007 Management Incentive Plan (the “2007 Stock Plan”) and the 2011 Stock Incentive Plan (the “2011 Stock Plan”). Under these plans, 1,987,412 shares of authorized common stock have been reserved for issuance pursuant to grants approved by the Company’s Board of Directors (the “Board”). All grants are made at 100% of the fair value at the date of grant. Options granted under the 2007 Stock Plan vest 20% at the date of grant and 20% on the anniversary date of the grant each year thereafter for four years. Options granted under the 2011 Stock Plan vest 20% on the anniversary date of the grant each year for five years. In addition, these options vest and become exercisable in full under certain circumstances following the occurrence of a Change of Control as defined in the Option Award Agreements. Participants who are awarded options must exercise their options within a maximum of ten years of the grant. As of March 31, 2014, there were 498,128 and 447,790 shares available for grant under the 2011 Stock Plan and 2007 Stock Plan, respectively. However, the Company no longer intends to grant awards under the 2007 Stock Plan.
	The Company recognizes compensation expense in the financial statements for all stock-based payments based upon the fair value.
	The fair value of option grants are estimated on the grant date using the Black-Scholes option-pricing model with the following assumptions for option grants during the three months ended March 31, 2013. No stock options were granted in the three months ended March 31, 2014.

	Expected dividends		0	%
	Expected term (in years)		10
	Risk-free rate		1.76	%
	Vesting period (in years)		5
	Expected volatility is based on the historic volatility of a publicly-traded company in the same industry. The risk free interest rate is based on the U.S. Treasury yield at the date the Board approved the option awards for the period (nine to ten years) over which options are exercisable.
	For the three months ended March 31, 2014 and 2013, the Company recorded stock-based compensation expense in the amount of $201 and $179, respectively. As of March 31, 2014, unrecognized stock-based compensation expense to be recognized over future periods approximated $2,749. This amount will be recognized as expense over a period of 3.5 years. The total income tax benefit recognized in the income statement for the stock-based compensation arrangements was $77 and $70 for the three months ended March 31, 2014 and 2013, respectively.

Accounting Policies [Abstract]	'
Nature of business	'
	Nature of business: The Company was incorporated and began operations in 1987. The Company is engaged in the consumer finance business, offering small installment loans, large installment loans, automobile purchase loans, retail purchase loans, and related credit insurance. As of March 31, 2014, the Company operated offices in 281 locations in the states of Alabama (49 offices), Georgia (3 offices), North Carolina (29 offices), New Mexico (8 offices), Oklahoma (27 offices), South Carolina (70 offices), Tennessee (21 offices), and Texas (74 offices) under the names Regional Finance, RMC Financial Services, Anchor Finance, Superior Financial Services, First Community Credit, AutoCredit Source, RMC Retail, and Sun Finance. The Company opened 17 new offices during the three months ended March 31, 2014.
Seasonality	'
	Seasonality: Our loan volume and corresponding finance receivables follow seasonal trends. Demand for our loans is typically highest during the third and fourth quarter, largely due to customers borrowing money for back-to-school and holiday spending. Loan demand has generally been the lowest during the first quarter, largely due to the timing of income tax refunds. During the remainder of the year, we typically experience loan growth from general operations. In addition, we typically generate higher loan volumes in the second half of the year from our direct mail campaigns, which are timed to coincide with seasonal consumer demand. Consequently, we experience significant seasonal fluctuations in our operating results and cash needs.
Principles of consolidation	'
	Principles of consolidation: The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation. The Company operates through a separate subsidiary in each state.
	The accounting and reporting policies of the Company are in accordance with GAAP and conform to general practices within the consumer finance industry.
Use of estimates	'
	Use of estimates: The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and disclosure of contingent assets and liabilities for the periods indicated in the financial statements. Actual results could differ from those estimates.
	Material estimates that are particularly susceptible to change relate to the determination of the allowance for credit losses, fair value of stock based compensation, the valuation of deferred tax assets and liabilities, and the allocation of the purchase price to assets acquired in business combinations.
Reclassifications	'
