Subprime auto loans are car loans made to borrowers with credit scores below roughly 660, and they come with interest rates that run two to three times what prime borrowers pay. Average APRs in late 2025 ranged from about 13% on a new car in the subprime tier to nearly 22% on a used car in the deep subprime tier, compared with roughly 7% for prime borrowers on a new vehicle. These loans keep millions of people driving to work who otherwise couldn’t finance a car at all, but they carry traps that can leave you owing thousands more than the vehicle is worth.
Where Your Credit Score Puts You
Auto lenders sort applicants into five tiers, and the tier drives nearly every term in the loan:
- Super prime (781–850): the best rates and the widest choice of lenders.
- Prime (661–780): competitive rates, slightly above super prime.
- Near prime (601–660): rates start climbing noticeably.
- Subprime (501–600): rates roughly double what prime borrowers pay, with fewer lenders willing to approve you.
- Deep subprime (300–500): the most expensive tier, often limited to specialized finance companies and buy-here-pay-here lots.
One wrinkle: many auto lenders use industry-specific scoring models rather than the FICO 8 score shown on a typical credit app. These auto scores weigh your history with car payments more heavily and run on a 250–900 scale instead of 300–850.1myFICO. FICO Score Versions Your auto-specific score can differ from the general score you see on a monitoring app by several dozen points in either direction.
What the Interest Rate Actually Costs
The monthly payment difference between a prime and subprime loan can look manageable. The lifetime cost difference is not.
On a $25,000 used car financed for 72 months, a prime borrower at 7% pays about $5,600 in total interest. A subprime borrower at 19% pays roughly $16,500 in interest on the same car. That’s nearly $11,000 more for the identical vehicle, before fees.
Interest on these loans almost always uses the simple interest method, where charges accrue daily against your remaining balance.2Consumer Financial Protection Bureau. What’s the Difference Between a Simple Interest Rate and Precomputed Interest on an Auto Loan? That’s good news if you can pay early or add extra toward principal, because you shrink the balance that interest accrues against. Pay late and more of the next payment gets eaten by interest instead of reducing what you owe.
Federal law requires every auto lender to give you a written disclosure before you sign, showing the APR, total finance charge, total of payments, and amount financed. Those figures must be clearly separated from the rest of the contract so you can compare offers.3Office of the Law Revision Counsel. 15 USC 1638 – Transactions Other Than Under an Open End Credit Plan If a dealer rushes you past this disclosure, slow down.
Dealer Markup You Don’t See
When you finance through a dealership, the dealer submits your application to multiple lenders. Each lender responds with a “buy rate,” the interest rate they’re willing to offer based on your credit profile. The dealer can then add a markup on top of that buy rate and keep the difference. The rate quoted at the finance desk is not necessarily the rate the lender set.
That markup is discretionary and negotiable, though dealers rarely say so. The CFPB has flagged the practice as a fair-lending risk, noting that discretionary markups can produce pricing disparities tied to race or national origin.4Consumer Financial Protection Bureau. Bulletin re: Indirect Auto Lending and Compliance with the Equal Credit Opportunity Act The practical move for a subprime borrower is to get pre-approved by a bank or credit union before you walk onto the lot. Even if the pre-approval isn’t great, it gives you a floor to measure the dealer’s offer against.
Down Payment, Loan Term, and Going Underwater
Subprime loans increasingly stretch to 72 or 84 months. Nearly 30% of new-vehicle loans originated in late 2025 ran 73 to 84 months, and some lenders are pushing past 85. Longer terms shrink the monthly payment, which is how expensive cars get sold as affordable. The trade-off is that a seven-year loan on a depreciating asset almost guarantees you’ll owe more than the car is worth for years.
That’s called being underwater, or carrying negative equity. CFPB research has found that rolling negative equity into a new loan pushes borrowers even further underwater on the next vehicle and raises the risk of a deficiency balance if they can’t keep up.5Consumer Financial Protection Bureau. Negative Equity Findings from the Auto Finance Data Pilot By late 2025, about 29% of trade-ins toward new vehicle purchases were underwater, with the average shortfall at a record $7,214.
This is why lenders push for a down payment, usually at least 10% of the purchase price or $1,000 in cash or trade-in equity. Money down lowers the loan-to-value ratio from day one and cushions you against depreciation. Every dollar down also reduces the balance that accrues interest over the life of the loan. A larger down payment is one of the most effective ways to cut the total cost of a subprime loan.
Fees Stacked on the Loan
Subprime loans tend to carry more fees than conventional auto financing: origination fees, application processing fees, and sometimes prepayment penalties that discourage early payoff. These get folded into the amount financed, so you pay interest on the fees themselves over the full term.
Dealer documentation fees vary widely by location. Some states cap them, others let dealers charge what the market will bear. State usury laws sometimes limit the maximum rate on auto loans, though ceilings vary and many states carve out exemptions for licensed motor vehicle finance companies. If you suspect you’re being charged above a legal limit, your state attorney general’s office can tell you what cap applies.
Who the Subprime Lenders Are
Three kinds of lenders dominate this market, and the differences matter.
Captive finance companies are the lending arms of vehicle manufacturers. They exist partly to move inventory and sometimes approve applicants outside lenders won’t touch, though their promotional rates rarely extend to subprime borrowers.
Indirect lenders are the banks and finance companies that work through dealerships. This is where dealer markup enters the picture.
Buy-here-pay-here (BHPH) dealerships act as both seller and lender, financing the car themselves. They serve the deep subprime market, and they come with two significant downsides. Interest rates at BHPH lots are among the highest in the industry. And many BHPH dealers only report negative payment information to the credit bureaus, so on-time payments may do nothing to rebuild your credit while a single missed payment still hurts you.6Consumer Financial Protection Bureau. What Is a “No Credit Check” or “Buy Here, Pay Here” Auto Loan or Dealership? If you go the BHPH route, ask the dealer to commit in writing to reporting on-time payments to at least one major bureau.
Spot Delivery and Yo-Yo Financing
One of the more predatory practices in subprime auto sales is spot delivery, also called yo-yo financing. You negotiate the deal, sign the paperwork, and drive the car home, but the financing hasn’t actually been approved by a lender. Days or weeks later the dealer calls to say the original terms fell through and pressures you to accept a higher rate, a larger down payment, or both. If you refuse, they demand the car back.
By then you’ve probably sold or traded your old vehicle, cancelled your previous insurance, and emotionally committed to the car. The paperwork you signed likely included a seller’s right-to-cancel clause buried in the retail installment contract. This tactic hits subprime borrowers hardest because their financing is genuinely harder to place, which gives the dealer a plausible excuse to renegotiate.
The defense is straightforward: don’t drive the car home until financing is confirmed in writing by the actual lender, not just the dealer. If you’ve already been caught in this situation and the new terms are dramatically worse, your state attorney general’s office may enforce specific rules on conditional delivery.
Before You Add a Co-Signer
Subprime borrowers are often told a co-signer will improve approval odds or lower the rate. That’s often true, but the co-signer takes on enormous risk. Federal law requires the lender to give every co-signer a separate written notice before they become liable. The notice must explain that the co-signer may have to pay the full amount if the primary borrower doesn’t, that the lender can come after the co-signer without first pursuing the borrower, and that a default will appear on the co-signer’s credit record.7eCFR. 16 CFR Part 444 – Credit Practices
A co-signer is legally distinct from a co-buyer. A co-signer guarantees the debt as a favor and gets no ownership interest in the car. A co-buyer shares both the obligation and the vehicle. If you’re asked to co-sign, you’re accepting the same collection methods that could be used against the primary borrower, including lawsuits and wage garnishment, with no claim to the car itself.
GAP Insurance Is More Than Optional for Subprime Borrowers
Because subprime borrowers go underwater so quickly, guaranteed asset protection (GAP) coverage deserves serious thought. Standard auto insurance only pays the current market value of the car if it’s totaled or stolen. If you owe $18,000 on a car worth $12,000, your insurer pays $12,000 and you’re on the hook for the $6,000 difference. GAP coverage fills that gap.8Consumer Financial Protection Bureau. What Is Guaranteed Asset Protection (GAP) Insurance?
Dealers often offer to roll GAP into the loan at purchase. That’s convenient but expensive, because financing the premium means paying interest on it for the full term. Buying GAP through your auto insurance carrier or a credit union is almost always cheaper. GAP is optional, and high-pressure tactics to add it at the finance desk should make you cautious about whatever else the dealer is adding.
GPS and Starter-Interrupt Devices
Many subprime lenders require borrowers to accept GPS tracking and starter-interrupt technology installed in the vehicle. The GPS lets the lender locate the car quickly if repossession becomes necessary. A starter-interrupt device goes further, allowing the lender to remotely prevent the car from starting if a payment goes past due. The devices typically warn you with beeping or flashing lights as the deadline approaches before cutting the ignition.
These devices must be disclosed before you sign. Manufacturers and lenders say the technology can only prevent a car from starting, not shut it off while moving. Some borrowers have disputed that. Several states have introduced legislation requiring written disclosure of tracking devices and advance notice before the ignition is disabled.
The privacy issue is real too. A GPS device transmitting your location to a lender around the clock creates a detailed record of your movements. If you’re required to accept one of these devices, make sure the loan agreement spells out exactly when and how the lender can use the data and disable the vehicle.
Repossession and the Deficiency Balance
If you default, the lender can repossess the car. Under the Uniform Commercial Code adopted in most states, a secured creditor can take the vehicle without going to court, as long as the repo doesn’t breach the peace.9Legal Information Institute. UCC 9-609 – Secured Party’s Right to Take Possession After Default A repo agent can come to your driveway at 3 a.m. They can’t break into your garage or threaten you.
Federal law does not require a lender to warn you before repossession. Once you’re in default the lender can take the car at any time, without notice, and can come onto your property to do it.10Federal Trade Commission. Vehicle Repossession State laws vary on whether you can cure the default by catching up on missed payments, and on what notice the lender must send after the car is taken.
Repossession doesn’t end the debt. After the lender sells the car, usually at auction for well below market value, they calculate a deficiency balance: the loan balance minus the sale price, plus the cost of repossessing, storing, preparing, and auctioning the vehicle. If you owed $15,000 and the car sold for $5,000 at auction with $800 in repo costs, you still owe $10,800. The lender can sue you for it, send it to collections, or both. For subprime borrowers who were already underwater, deficiency balances in the thousands are common.
Active-Duty Servicemembers: A Rate Cap That Only Covers Pre-Service Loans
Active-duty servicemembers who took out a car loan before entering military service get a break under the Servicemembers Civil Relief Act. The SCRA caps interest at 6% per year on pre-service debts, and the cap includes fees and service charges, not just the stated interest rate.11Office of the Law Revision Counsel. 50 USC 3937 – Maximum Rate of Interest on Debts Incurred Before Military Service Any interest above 6% is forgiven, and the monthly payment must be reduced.
To claim the reduction, send the lender written notice with a copy of your military orders. The request can be made up to 180 days after the end of military service.12U.S. Department of Justice. Your Rights as a Servicemember: 6% Interest Rate Cap for Servicemembers on Pre-service Debts The protection also covers joint debts where both servicemember and spouse are named.
The important limit: the cap only applies to debts incurred before active duty. A car loan taken out while already serving isn’t covered. The separate Military Lending Act covers some consumer loans for active-duty members but specifically excludes purchase-money auto loans where the vehicle secures the debt.13Consumer Financial Protection Bureau. What Is Covered Under the Military Lending Act? The MLA does cover vehicle title loans, so a servicemember borrowing against a car they already own falls under different rules.
Refinancing Out of a Subprime Loan
A subprime rate isn’t permanent. If your credit score has improved since origination, or if market rates have dropped, refinancing can save thousands. There’s no universal minimum score and no mandatory waiting period. What matters is whether your credit profile looks materially better than it did when you signed.
Start by pulling your credit reports and disputing any errors dragging your score down. Then shop. Your current lender may refinance, though some won’t. Banks, credit unions, and online lenders all offer auto refinancing, and comparing three or four offers takes less than an afternoon. Focus on the APR, not the monthly payment. A lender who offers a lower monthly payment by stretching the term to 84 months isn’t doing you a favor if total interest paid goes up.
Refinancing works best when you’ve built enough equity that a new lender sees a reasonable loan-to-value ratio. If you’re deeply underwater, lenders may not want to refinance because the car isn’t worth enough to secure the new loan. Extra payments toward principal, or simply waiting for depreciation to slow, can put you in a stronger position. Even a two- or three-point rate reduction on a subprime balance adds up to real money over the remaining term.
