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

Bad credit does not automatically disqualify you from refinancing a car loan. Lenders do refinance for borrowers with credit scores below 620, but they charge higher interest rates to offset the risk. Your new rate may be only slightly better than what you're paying now, or it might not be better at all — which is why checking your actual offers before committing matters more than your credit score alone.

The core challenge is that fewer lenders will consider you. Large banks and credit unions often have minimum credit score requirements of 650 or higher. Subprime lenders and buy-here-pay-here dealerships will work with lower scores, but their rates reflect that. You'll also face stricter terms: shorter loan lengths, higher down payments, or requirements to add a co-signer.

The math only works if your new rate is meaningfully lower than your current one, or if you're extending the loan term to lower your monthly payment. Extending the term costs you more in total interest, so that trade-off is real.

Key Takeaways

  • Bad credit refinancing is available through subprime lenders and some credit unions, but interest rates will be higher than for borrowers with good credit.
  • You need at least some equity in the car — owing less than it's worth — because lenders won't refinance an underwater loan regardless of your credit.
  • Getting pre-approval quotes from multiple lenders shows you the actual rate you'd receive before you explore, without damaging your credit score.
  • Refinancing only makes financial sense if your new rate is at least 1 to 2 percentage points lower than your current rate, or if you need to lower your monthly payment for cash flow reasons.
  • Adding a co-signer with better credit can improve your rate, but they become legally responsible for the loan if you stop paying.

Where to find lenders willing to refinance bad credit

Credit unions often have more flexible credit requirements than banks, and they typically charge lower rates. If you belong to a credit union, start there — many will refinance members with scores in the 580–620 range. You do not need to be a member to join most credit unions; some are open to the public, while others require membership in a specific employer, union, or community.

Subprime auto lenders specialize in borrowers with bad credit and will refinance loans for scores as low as 500. Companies like LendingClub, Upgrade, and Pave operate online and can give you a pre-approval in minutes. The trade-off is that their rates are higher — often 8% to 15% or more depending on your score and the car's age.

Online lenders and peer-to-peer platforms sometimes offer better rates than subprime specialists, though approval is not may provide. Traditional banks rarely refinance for bad credit unless you add a co-signer with good credit.

Avoid dealerships offering "in-house" refinancing or "buy-here-pay-here" loans unless you have no other option. These often come with GPS tracking, starter interrupt devices, or payment requirements that make them more expensive and restrictive than a traditional refinance.

What lenders will check before they say yes

Lenders will pull your credit report and verify your income, employment, and current loan details. They'll also check the car's value using tools like NADA Guides or Kelley Blue Book. If you owe more than the car is worth, most lenders will decline — this is called being "underwater" on the loan, and it's a hard stop for refinancing.

You'll need to provide proof of income (recent pay stubs or tax returns), proof of residence (utility bill or lease), and your current loan documents. Some lenders ask for proof of insurance. Have these ready before you explore to speed up the process.

Your employment history matters more with bad credit. Lenders want to see stability — at least two years at the same job or in the same field. Frequent job changes raise red flags, even if your income is steady.

How to compare offers and avoid predatory terms

Get pre-approval quotes from at least three lenders before you commit. Pre-approval checks your credit with a soft inquiry, which does not lower your score. Hard inquiries (the kind that happen when you formally explore) do lower your score slightly, but multiple hard inquiries within 14 days count as one inquiry for credit scoring purposes, so shopping around is safe.

Compare the interest rate, the loan term (length), and the total amount you'll pay over the life of the loan. A lower monthly payment might look good, but if it comes from extending the loan from 48 months to 72 months, you're paying thousands more in interest. Use an auto loan calculator to see the total cost.

Watch for prepayment penalties, which charge you a fee if you pay off the loan early. Some subprime lenders include these; others don't. If you plan to pay faster, a loan without prepayment penalties saves you money.

Avoid loans that require a GPS tracker, starter interrupt device, or payment app that charges fees. These are common in subprime lending and add real costs beyond the interest rate.

Adding a co-signer to improve your rate

A co-signer with good credit can lower your interest rate by 1 to 3 percentage points. The co-signer does not need to own the car or make payments — they're straightforward promising the lender they'll pay if you don't. This is a serious commitment for them, and it affects their credit and their ability to borrow.

Most lenders will allow a co-signer on a refinance. Some require the co-signer to be present when you sign the papers; others allow them to sign remotely. Ask the lender about their process before you ask someone to co-sign.

If your co-signer's credit is only slightly better than yours, the rate improvement may be small. The lender will still pull both credit reports and consider both of your incomes and debts.

When refinancing makes financial sense with bad credit

Refinancing only saves money if your new rate is at least 1 to 2 percentage points lower than your current rate. With bad credit, that's harder to achieve. If you're currently paying 12% and a subprime lender offers 10%, that's a real savings. If they offer 11.5%, the savings are minimal and may not be worth the process fees and credit inquiry.

The exception is if you need to lower your monthly payment for cash flow reasons, even if the total interest cost goes up. If you're struggling to make your current payment, refinancing to a longer term might prevent a default — and a default damages your credit far more than a refinance does.

Calculate the break-even point: how many months until the interest you save exceeds any fees you pay. If you plan to sell or trade the car within that timeframe, refinancing doesn't make sense.

How bad credit refinancing affects your credit score

The hard inquiry from explore lowers your score by a few points — usually 5 to 10 points. This effect fades after a few months. Opening a new loan account also lowers your score temporarily because it reduces your average account age and adds a new hard inquiry.

Over time, refinancing can help your credit if you make on-time payments on the new loan. It also lowers your credit utilization if you're paying off other debts with the money you save on your car payment.

The short-term score dip is worth it if the refinance saves you money or improves your cash flow. Just avoid explore for multiple refinances in a short period — each process is a hard inquiry, and too many in a few months signals financial distress to lenders.

Alternatives if refinancing isn't available or affordable

If no lender will refinance you, or every offer is worse than your current loan, you have other options. Loan modification through your current lender sometimes works — call and ask if they'll extend your term or lower your rate without a full refinance. Some lenders do this to keep you from defaulting.

If your car payment is the problem, selling the car and buying a cheaper one outright (or with a smaller loan) might be faster than waiting for your credit to improve. You'll owe your current lender the payoff amount, but if the car is worth more than you owe, you can use the difference toward a cheaper vehicle.

Improving your credit score before refinancing is another path. Paying down credit card balances, fixing errors on your credit report, and making on-time payments for 6 to 12 months can raise your score enough to may have access to for better rates. This takes time but costs nothing.

Frequently Asked Questions

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

Most lenders will not refinance if you're currently behind on payments. You'll need to bring the loan current first — meaning you owe no past-due amounts. Some lenders will refinance if you're only one or two payments behind, but this is rare. Call your current lender and ask about catching up before you explore elsewhere.

What if my car is worth less than I owe on it?

You cannot refinance an underwater loan with traditional lenders. Some subprime lenders will roll the negative equity into a new loan, but this means you'll owe even more and pay more interest. This is usually a bad deal. Wait until you've paid down the loan enough to have equity, or sell the car and pay the difference out of pocket.

How long does bad credit refinancing take?

Pre-approval usually takes 24 to 48 hours. Final approval and funding can take 5 to 10 business days once you've submitted all documents. Some online lenders fund within 2 to 3 days. The payoff of your old loan happens automatically once the new lender receives the funds.

Will refinancing hurt my credit score permanently?

No. The hard inquiry and new account lower your score temporarily, but the effect fades after a few months. Making on-time payments on the new loan actually helps your credit over time. A default or missed payment hurts far more than a refinance does.

Do I need to tell my current lender I'm refinancing?

You do not need to tell them in advance. Once the new lender approves you, they'll contact your current lender directly to get the payoff amount and arrange the transfer. Your current loan will be paid off automatically, and you'll start making payments to the new lender.
