What Makes a Loan 'Subprime'?
In auto financing, the term subprime refers to loans extended to borrowers whose credit profiles present elevated risk to a lender. While there is no single universal threshold, subprime borrowers are broadly defined as those with a FICO score below approximately 620, though lenders set their own cutoffs. Deep subprime typically describes scores below 580.
Lenders price subprime loans to compensate for a statistically higher probability of default. That compensation comes in the form of a higher annual percentage rate (APR), stricter loan-to-value requirements, and sometimes shorter approved loan amounts. It is important to understand that "subprime" describes a loan structure, not a permanent label on the borrower - credit situations change, and so can financing options over time.
For context on how loan duration interacts with rate, see our breakdown of short-term vs. long-term auto loans.
Subprime Lending Is a Spectrum
Not all subprime loans carry identical terms. Credit unions, community banks, and online lenders each apply their own underwriting criteria and rate schedules. A score of 590 may qualify for meaningfully different rates at different institutions. This makes comparison shopping particularly important in the subprime tier - perhaps more so than in prime lending, where rates tend to be more compressed.
The Advantages: Why Buyers Consider Subprime Financing
Despite the higher costs, subprime auto loans offer several genuine benefits that explain their persistent demand in the market.
Provides access to financing when prime options are unavailable
For buyers with damaged credit, a subprime loan may be the only path to vehicle ownership. This matters especially when reliable transportation is essential for employment or other obligations.
On-time payments can help rebuild credit history
An installment loan reported to major credit bureaus gives borrowers a structured opportunity to demonstrate responsible repayment behavior, which can gradually improve credit scores over time.
Approval criteria are more flexible than prime loans
Subprime lenders typically evaluate a broader set of factors - including income, employment stability, and down payment - rather than disqualifying applicants on credit score alone.
Offers a defined path toward refinancing at better rates
Borrowers who improve their credit profile during the loan term may become eligible to refinance at a lower rate, reducing the total interest cost from the original agreement.
For buyers working to repair credit, on-time monthly payments on an installment loan are reported to the major credit bureaus and can contribute positively to payment history - the single largest factor in most credit scoring models. This is not guaranteed improvement, but consistent, on-time performance generally moves the needle.

The Disadvantages: Costs and Risks to Weigh Carefully
The trade-offs in subprime lending are significant and deserve an honest assessment before any application is submitted.
Significantly higher APR than prime auto loans
Subprime borrowers routinely pay APRs multiple percentage points above prime rates. On a $20,000 loan over 60 months, even a 10-percentage-point APR difference can add several thousand dollars to total repayment cost.
Greater risk of negative equity over time
When loan balances depreciate more slowly than the vehicle itself - common with high-APR, long-term loans - borrowers can end up owing more than the car is worth, limiting their options if they need to sell or trade in.
Some agreements include prepayment penalties or add-on products
Certain subprime loan contracts contain prepayment penalties that reduce the benefit of early payoff, or include optional products like GAP coverage bundled into the loan at additional cost.
Missing payments carries amplified consequences
Borrowers already near credit thresholds face steeper score impacts from late payments, and some subprime contracts include starter-interrupt devices or faster repossession timelines than prime agreements.
~620
Typical credit score threshold for subprime auto loans
Most major lenders classify borrowers with FICO scores below approximately 620 as subprime, though individual lender cutoffs vary.
10%+
Typical APR premium over prime borrowers
Industry data consistently shows subprime auto loan APRs running well above prime rates, with deep subprime borrowers sometimes facing rates exceeding 20% APR.
Loan term length amplifies these costs. A higher APR on a 72-month term can result in paying more in interest than the vehicle's depreciated value by the loan's midpoint - a condition known as being underwater or having negative equity. Borrowers should calculate total repayment cost, not just monthly payment, before agreeing to terms.

Strategies to Improve Your Position Before Applying
Even within the subprime tier, borrowers are not without options for improving their financing outcome. A few targeted steps can meaningfully affect the rate and terms a lender offers.
- Review your credit report first. Errors on credit files are not uncommon and can suppress your score below its accurate level. Disputing inaccuracies before applying costs nothing and can shift your rate bracket.
- Make a larger down payment. Reducing the loan-to-value ratio lowers lender risk and may result in better terms. It also reduces the risk of negative equity.
- Shop multiple lenders. Subprime rates vary considerably across credit unions, community banks, and online lenders. Rate shopping within a short window - typically 14 to 45 days depending on the scoring model - is generally treated as a single inquiry. See our article on rate shopping without damaging your credit score for specifics.
- Plan for refinancing. If you make consistent on-time payments over 12 to 18 months and your credit score improves meaningfully, refinancing into a lower-rate loan may become available. Build this as an explicit part of your strategy from the outset.
Before submitting any application, working through a credit readiness checklist can help you identify gaps and present the strongest possible application.
