Refinancing a car loan with bad credit is possible, but you will pay higher interest rates and have fewer lenders willing to work with you

Refinancing means replacing your current car loan with a new one, usually from a different lender. When your credit score is low, most traditional banks and credit unions will decline you outright. Your realistic options are credit unions that specialize in second-chance lending, online lenders that accept lower credit scores, and sometimes your current lender (who already knows your payment history). The catch: these lenders charge higher interest rates to offset their risk, so refinancing only makes sense if your current rate is significantly higher or if you need to lower your monthly payment badly enough that a higher total cost is worth it.

The decision to refinance should rest on one question: will I pay less in total interest, or will I save enough on my monthly payment to justify paying more overall? Many people refinance and end up paying more because they extend the loan term without checking the math first.

Key Takeaways

  • Credit unions and online lenders are more likely to refinance a car loan with bad credit than traditional banks, though their interest rates will be higher than what borrowers with good credit receive.
  • Refinancing makes financial sense only if the new interest rate is at least 1 to 2 percentage points lower than your current rate, or if you need to extend the loan term to reduce your monthly payment.
  • Your current lender may refinance you without a hard credit pull, so calling them first costs nothing and takes minutes.
  • The amount you still owe on the car (called the loan balance) must be less than or close to what the car is worth, or lenders will refuse the refinance.
  • Refinancing resets your loan term, so extending a loan from 3 years to 5 years lowers your payment but means you pay interest for longer.

When refinancing actually saves you money

Before you pursue refinancing, do the math. Pull your current loan documents and write down three things: your current interest rate, how many months remain on the loan, and your current monthly payment. Then calculate what you would pay in total interest if you kept the loan as is. This is your baseline.

Refinancing only makes sense if the new loan's total interest cost is lower than what you are currently paying, even after accounting for any fees the new lender charges. If your current rate is 12% and you can refinance at 10%, that is a meaningful drop. If your current rate is 12% and the best offer you get is 11%, the savings are usually too small to justify the paperwork and the hard credit inquiry (which temporarily lowers your score by a few points). The exception is if you need to lower your monthly payment right now — in that case, extending the loan term might be worth paying more interest overall.

Lenders that work with bad credit

Credit unions are often your best first stop. Many credit unions, especially those focused on second-chance lending or those affiliated with your employer or community, will refinance a car loan even with a credit score in the 500s or 600s. Call or visit in person and ask directly whether they refinance existing auto loans for members with lower credit scores. Some credit unions will refinance without pulling your credit hard, meaning the inquiry does not show up on your credit report.

Online lenders like LendingClub, Upgrade, and Upstart advertise that they work with lower credit scores. These lenders typically pull your credit hard (which does show on your report), but they move faster than banks — sometimes approving and funding within days. Interest rates are higher than credit unions, but the speed can matter if you need cash flow relief quickly. Read the fine print: some online lenders charge origination fees (a percentage of the loan amount deducted upfront) or prepayment penalties (a fee if you pay off the loan early).

Your current lender is worth calling before you shop elsewhere. If you have been making on-time payments, they may refinance you at a better rate without a hard credit pull. They already have your history and know you are not a flight risk. This conversation takes ten minutes and costs nothing.

The loan-to-value problem

Lenders will not refinance a car loan if you owe more than the car is worth. This situation is called being "upside down" on the loan. For example, if your car is worth $8,000 but you still owe $10,000, most lenders will decline because if you default, they cannot recover their money by selling the car.

Check your car's value using Kelley Blue Book or NADA Guides — both are free and widely used by lenders. Then compare that value to your loan balance (which appears on your loan statement or your lender's website). If you owe less than the car is worth, you are in the clear. If you owe more, refinancing is unlikely unless you can find a lender willing to roll the negative equity into a new loan — which means you would owe even more total and pay interest on the difference. This is rarely a good deal.

Documents you will need

Lenders will ask for proof of income (recent pay stubs or tax returns), proof of residence (a utility bill or lease), and your driver's license. They will also need your current loan documents or the lender's account number so they can verify what you owe and at what rate. Have your car's Vehicle Identification Number (VIN) ready — it appears on your registration and insurance card.

Some lenders will ask for proof of insurance before they fund the new loan. This is standard and protects them in case the car is damaged. Your current insurance policy is fine; you do not need to switch insurers.

What happens to your credit score during refinancing

When a lender pulls your credit to consider refinancing, that inquiry lowers your score by a few points — usually 5 to 10 points. The impact is temporary and recovers within a few months. If you shop around with multiple lenders within a two-week window, the credit bureaus typically count all those inquiries as a single inquiry, so you do not get penalized multiple times.

Once you refinance, your old loan closes and a new one opens. Closing the old loan removes an active account from your credit report, which can lower your score slightly. Opening the new loan adds a new account, which also lowers your score temporarily. Over time, making on-time payments on the new loan will rebuild your score faster than staying in a high-interest loan you struggle to pay.

The cost of extending your loan term

If you refinance and extend your loan from 48 months to 60 months, your monthly payment drops — but you pay interest for an extra year. Use an auto loan calculator to see the real numbers. For example, 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 total interest. If you refinance that same $15,000 at 10% over 60 months, your payment drops to about $318 per month — but you now pay about $3,080 in total interest. You save $57 per month but pay $80 more overall.

This trade-off is sometimes worth it if you are struggling to make your current payment and need breathing room. Just go in with eyes open: you are paying more total interest to lower your monthly burden. Before you extend the term, ask yourself whether your financial situation will improve in the next year or two — if it will, you might be better off keeping the shorter term and pushing through the higher payment.

Frequently Asked Questions

Can I refinance if I am behind on payments?

Most lenders will not refinance if you are currently behind. Some credit unions may work with you if you are only one or two payments behind and can catch up when ready, but this is rare. If you are behind, contact your current lender first to discuss a loan modification or payment plan before pursuing refinancing elsewhere.

What if I have a co-signer on my current loan?

When you refinance, you can refinance with just your name if your credit has improved, or you can keep the co-signer on the new loan. Removing a co-signer requires their consent and may affect your approval odds. Discuss this with the new lender before you explore.

How long does refinancing take?

Credit unions typically take 3 to 7 business days after approval. Online lenders can fund within 1 to 3 days. Your current lender will be paid off automatically, and the new lender will send you new loan documents and a payment schedule. You do not need to do anything except start making payments to the new lender.

Will refinancing hurt my credit score permanently?

No. The hard inquiry and the account changes lower your score temporarily — usually by 10 to 20 points — but the impact fades within a few months. Making on-time payments on the new loan rebuilds your score faster than the temporary dip hurts it.

What if no lender will refinance me?

If refinancing is not an option, focus on making your current payments on time. Your credit score will improve over time, and in 12 to 24 months you may have better refinancing options. In the meantime, paying down the principal (the amount you owe) faster will reduce the total interest you pay — even small extra payments help.
