Bad Credit Auto Loan Calculator: A 2026 Guide
A credit score under 620 does not lock you out of a car loan — but it does change the math dramatically. Subprime and deep-subprime borrowers routinely face 15-25% APRs, which can double the cost of the car over a 60-month term. This 2026 bad credit auto loan calculator translates your credit score into a realistic APR estimate, monthly payment, and total interest cost so you can see what you are actually signing up for. Enter your score, vehicle price, down payment, and income, and the calculator returns estimated APR by credit tier with the monthly payment that comes with it.
How credit score maps to APR
Auto lenders tier borrowers by credit score, and each tier historically carries a typical APR range (consistent with Experian's published automotive finance data). Super-prime (781-850): roughly 5-7%. Prime (661-780): roughly 6.5-9%. Near-prime (601-660): roughly 9-13.5%. Subprime (501-600): roughly 13.5-18.5%. Deep subprime (300-500): 18.5% and up. These ranges shift with Federal Reserve policy and market conditions, so treat them as illustrative bands rather than today's exact quotes — the spread between tiers stays roughly constant, with a deep-subprime borrower paying 13-18 points more than a super-prime borrower for the same car. Confirm the live APR on your actual offer. On a $20,000 loan over 60 months, that spread is the difference between about $4,000 in total interest and $13,000+.
Down payment requirements for bad credit
Subprime lenders usually require 10-20% down to approve a loan — partly to reduce their risk, partly because negative equity in the first two years of a high-APR loan is severe. On an $18,000 car, that means $1,800-3,600 cash at signing. A larger down payment also lowers the APR by 0.5-1.5 percentage points at many lenders, because a lower loan-to-value ratio means less risk. If you cannot scrape together 10%, consider waiting and saving — the combination of a thin down payment and a 20% APR is a near-guaranteed path to being upside down for the entire loan term.
Where to get a bad credit auto loan
Four sources, ranked best to worst. Credit unions top the list — many accept members with scores in the 580s and offer APRs 3-8 percentage points below banks for the same score tier. Online subprime lenders (Capital One Auto Navigator, Carvana, Upstart) are second — fast pre-approval, no hard pull until you commit, but rates can still hit 18-22%. Franchise dealerships with captive lenders are third, useful for score recovery programs. Buy-here-pay-here lots are last resort only — APRs of 22-29%, weekly payments, and repossession after a single missed payment. Always get a credit union pre-approval first and use it as a benchmark.
The 12-month refinance escape hatch
The single most expensive mistake bad-credit borrowers make is keeping a subprime loan for the full term. A smarter path: take the best loan you can get now, make 12-18 months of on-time payments, then refinance into a prime or near-prime loan once your score crosses 660. Someone who starts at 19% APR on a $20,000 loan and refinances at 9% after 18 months saves roughly $3,000-4,500 in remaining interest — easily worth the $150-300 in refinance fees. Run both the current loan and the refinance scenario through our auto refinance calculator to see the exact break-even.
How much car you can actually afford
Lenders look at payment-to-income ratio, not just credit score. Most cap the car payment at 15-20% of gross monthly income. On $3,000/month gross, that is a $450-600 payment ceiling — which at 18% APR over 60 months supports a $14,000-18,000 loan. The car affordability calculator shows your real ceiling based on income, down payment, and APR. A common trap: buying more car than the payment-to-income ratio supports, then getting approved only at a higher APR or longer term that inflates total cost. Run the affordability numbers before shopping, not after.

How the math works
Subprime auto APRs are set by lenders using your credit tier (deep subprime < 580, subprime 580–619, etc.). They run far above prime rates; the formula is still standard amortization, but the high r produces large total interest. Verify any offered rate against your actual credit report.
How to use this calculator
- Check your real credit score from a free bureau source before shopping.
- Enter the APR a subprime lender actually quoted you (these vary widely — never assume).
- Model how a larger down payment lowers the principal and sometimes the rate tier.
- Compare the total interest against waiting and rebuilding credit; long subprime loans risk negative equity.
