Refinancing a car loan with bad credit is possible, but you'll pay more and have fewer lenders willing to work with you

Refinancing means replacing your current auto loan with a new one, usually from a different lender. With bad credit, most traditional banks and credit unions will decline you outright. Your realistic options are subprime lenders (companies that specialize in bad-credit borrowers), credit unions that serve specific communities, and sometimes your current lender if you've made on-time payments since you borrowed.

The catch: subprime refinance rates run 2 to 8 percentage points higher than what someone with good credit would pay. You might refinance to lower your monthly payment by extending the loan term, but you'll pay thousands more in interest over the life of the loan. Refinancing makes sense only if your current rate is unusually high, your payment is straining your budget, or you've improved your credit score since you took out the original loan.

Key Takeaways

  • Subprime lenders are the main source of refinance loans for people with bad credit, and they typically charge rates 2 to 8 percentage points higher than prime lenders.
  • Lowering your monthly payment by extending your loan term saves money each month but costs you more in total interest paid over the life of the loan.
  • Your current lender may refinance you if you have made consistent on-time payments, even if your credit score hasn't improved.
  • The car itself must have equity (you owe less than it's worth) and be in reasonable condition for most lenders to consider refinancing.
  • You'll need your current loan documents, proof of income, and a recent vehicle inspection report before you contact a lender.

Why your credit score matters to refinance lenders

Lenders use your credit score to predict whether you'll repay the new loan. A score below 620 is typically considered bad credit. At that level, prime lenders (banks and large credit unions) see you as too risky and won't refinance you. Subprime lenders accept lower scores because they charge higher rates to offset the risk.

Your payment history on the current loan also matters. If you've been late on payments, missed payments, or had the car repossessed and recovered it, refinancing becomes much harder. Subprime lenders will still consider you, but they'll charge the highest rates in their range. If you've made every payment on time for the past 12 months, even with a low credit score, you have a stronger case to present to lenders.

Where to find subprime auto refinance lenders

Start with online lenders that advertise bad-credit refinancing: LendingClub, Upgrade, and Lightstream all offer auto refinance loans. You can get a rate quote without a hard credit pull on most of these sites, which means checking won't damage your score. Compare at least three lenders before you commit.

Credit unions sometimes offer better rates than online subprime lenders, especially if you're a member or live in a state where you can join. Navy Federal, Pentagon Federal, and Connexus are open to people outside their original membership base. Local credit unions may also refinance bad-credit borrowers at lower rates than national subprime companies. Call your current lender first—many will refinance existing customers without running a full credit check if your payment history is clean.

Avoid buy-here-pay-here dealers and title loan companies. These are not refinance options; they're predatory lenders that take your car as collateral and charge rates of 100% or higher.

What lenders need from you before they'll consider refinancing

You'll need to provide proof that you have equity in the car—meaning the car is worth more than you owe on the current loan. Lenders typically use the National Automobile Dealers Association (NADA) guide or Kelley Blue Book to value your vehicle. You can check these yourself for free online; enter your car's year, make, model, mileage, and condition.

Gather your current loan documents, including the promissory note and payment history. Bring recent pay stubs (usually the last two months) and a recent tax return or bank statements to prove income. Some lenders will ask for a vehicle inspection report or recent maintenance records to confirm the car is in reasonable condition. A car with major mechanical problems or high mileage may not refinance, even with a subprime lender.

Have your driver's license, Social Security number, and proof of insurance ready. The lender will run a hard credit check when you formally explore, which will temporarily lower your score by a few points.

How refinancing changes your monthly payment and total cost

Refinancing lowers your monthly payment by extending the loan term—stretching a 48-month loan into 60 or 72 months, for example. A lower payment helps your monthly budget, but you pay interest for longer. If you owe $15,000 at 12% interest over 48 months, your payment is roughly $375 per month and you pay about $3,000 in interest. Refinancing that same $15,000 at 14% interest over 72 months lowers your payment to roughly $280 per month, but you pay about $5,200 in total interest—more than $2,000 extra.

The only scenario where refinancing saves you money overall is if the new rate is significantly lower than your current rate. This happens when your credit score has improved since you took out the original loan, or when you're refinancing from a predatory lender into a legitimate subprime lender. Use an online auto loan calculator to compare your current loan's total cost against the refinance offer before you decide.

What happens after you're approved for refinancing

Once approved, the new lender pays off your current loan in full. You then owe the new lender instead. This process typically takes 7 to 14 business days. During this time, you still owe your original lender, so keep making payments on schedule until you receive written confirmation that the loan has been paid off.

Your new lender will send you new loan documents and a payment schedule. Read these carefully to confirm the interest rate, term length, and monthly payment match what you were quoted. Some lenders charge origination fees (typically 1% to 5% of the loan amount), which may be rolled into the new loan balance. Ask about this before you sign.

After refinancing, your credit score will dip temporarily from the hard credit pull and the new account. It typically recovers within a few months if you make on-time payments on the new loan. Making consistent payments is the fastest way to improve your credit for future refinancing or other borrowing.

When refinancing doesn't make sense

Don't refinance if you're underwater on the loan—meaning you owe more than the car is worth. Lenders won't refinance you in this situation because they have no collateral cushion if you default. If you're underwater, focus on paying down the principal for 6 to 12 months, then revisit refinancing.

Don't refinance if you're planning to sell or trade in the car within the next year or two. The refinancing process costs money in fees and interest, and you won't recoup those costs in a short ownership window. Also avoid refinancing if you're behind on payments or facing a repossession. Refinancing won't stop a repossession in progress, and lenders won't work with you while you're delinquent.

Frequently Asked Questions

Can I refinance if I'm behind on my current car payment?

No. Lenders require that you be current on your existing loan before they'll refinance. If you're 30 or more days late, bring your account current first, then wait 3 to 6 months of on-time payments before explore. This shows lenders you're managing the debt responsibly.

What if my car is worth less than I owe?

You're underwater, and most lenders won't refinance you because they have no equity cushion. Keep making payments to reduce what you owe. Once the car is worth more than the loan balance, you can refinance. This typically takes 12 to 24 months depending on how far underwater you are.

Will refinancing hurt my credit score?

Yes, temporarily. The hard credit pull lowers your score by a few points, and opening a new account temporarily lowers it further. Your score typically recovers within 3 to 6 months if you make on-time payments on the new loan. The long-term benefit of a lower interest rate usually outweighs the short-term score dip.

How long does the refinancing process take?

From process to funding typically takes 7 to 14 business days. Some online lenders are faster (3 to 5 days), while credit unions may take longer. The new lender pays off your old loan during this time, so you don't have a gap in coverage.

Can I refinance with my current lender?

Yes, and it's often easier than refinancing with a new lender. Your current lender already knows your payment history. Call and ask if they offer refinancing for existing customers with bad credit. They may not run a hard credit check if you've been current on payments.
