Refinancing a car with bad credit is possible, but you will pay more for it

A car refinance means replacing your current auto loan with a new one, usually to lower your monthly payment or interest rate. With bad credit, lenders see you as higher risk, so they charge higher interest rates to offset that risk. You can still refinance — credit unions, banks, and online lenders all work with borrowers whose credit is below 620 — but the new rate may not be much better than what you have now, and sometimes it is worse. The real question is whether refinancing saves you money over the life of the loan, not whether you can do it.

Most people with bad credit refinance to lower their monthly payment, but that can actually cost you thousands more in total interest. Before you explore anywhere, you need to compare the total amount you will pay under the new loan to what you would pay if you kept your current one. A lower payment that stretches over more years is not always a win.

Key Takeaways

  • Refinancing with bad credit usually means a higher interest rate than borrowers with good credit receive, so compare the new rate to your current one before signing.
  • Credit unions often offer lower rates to members with bad credit than banks or online lenders do, especially if you have been a member for at least a few months.
  • Extending the loan term (stretching payments over more months) lowers your monthly payment but costs you more in total interest over time.
  • Your current lender may refinance you without a hard credit pull, which does not hurt your credit score the way a new lender's inquiry does.
  • Paying down the loan balance before refinancing improves your chances of approval and can result in a better rate.

Why your credit score affects the interest rate you are offered

Lenders use your credit score to predict whether you will pay back the loan on time. A lower score signals past missed payments, high debt, or other signs that you struggled to manage money. To compensate for the risk, lenders charge a higher interest rate. That higher rate is their insurance: if you default, the extra money they collected covers some of their loss.

The difference is real. A borrower with a 750 credit score might refinance at 5 percent, while a borrower with a 580 score might be offered 10 or 12 percent on the same car. Over five years, that gap adds thousands of dollars to what you pay. This is why checking whether refinancing actually saves you money — not just lowers your payment — matters so much.

Where to look for a refinance loan with bad credit

Credit unions are often the best starting point. They are member-owned, non-profit organizations, and they typically offer lower rates than banks or online lenders, even to members with bad credit. Many credit unions will refinance a car you bought elsewhere. You do not have to have been a member for years — some will work with you after 30 days of membership — but the longer you have been a member, the better your odds of approval and a lower rate. If you are not already a member, you can join most credit unions for a small fee (usually $5 to $25) and then refinance.

Banks will refinance cars for borrowers with bad credit, but their rates are usually higher than credit unions charge. Call your current bank first — they may offer you a better rate than a new lender would, since they already know your account history. Online lenders and car-specific refinance companies (like LendingClub, Upgrade, or Lightstream) also work with bad credit, but read the fine print carefully. Some charge origination fees, prepayment penalties, or require you to have a minimum income.

Before you explore anywhere, check your credit report at annualcreditreport.com (the only free site authorized by federal law). Look for errors — a missed payment that was not actually missed, or an account that is not yours. Disputing errors can raise your score before you explore, sometimes enough to move you into a better rate tier. This step costs nothing and takes a few weeks, but it can save you hundreds in interest.

The trade-off between monthly payment and total cost

When you refinance, you have two main levers: the interest rate and the loan term (how many months you have to pay it back). With bad credit, you cannot control the rate much — the lender sets it based on your score. But you can choose the term. A longer term means a lower monthly payment, which sounds good until you do the math.

Say you owe $15,000 on your car at 9 percent interest with three years left on your loan. Your current payment is about $470 a month. If you refinance at 10 percent (worse rate, but bad credit) over three years, your payment stays roughly the same but you pay more total interest. If you refinance over five years instead, your payment drops to about $320 — but you pay an extra $3,000 in interest over those two extra years. That $150 monthly savings costs you $3,000 in the end.

Before you sign, ask the lender for a loan estimate that shows the total amount you will pay over the life of the loan, not just the monthly payment. Compare that number to what you would pay if you kept your current loan. If the total is higher, refinancing does not save you money, even if the monthly payment is lower. This document is free and takes the lender a few minutes to produce.

How a hard credit inquiry affects your score

When you explore for a refinance loan, the lender pulls your credit report. This is called a hard inquiry (or hard pull), and it lowers your credit score by a few points — usually 5 to 10 points per inquiry. If you explore to five different lenders in one week, that is five separate hits to your score.

However, most credit scoring models treat multiple auto loan inquiries within 14 to 45 days as a single inquiry, so shopping around for the best rate does not hurt as much as it sounds. The damage is temporary — the inquiry falls off your report after two years and stops affecting your score after about one year. Your current lender may offer to refinance you with a soft inquiry instead, which does not hurt your score at all. Always ask before they pull your credit.

Steps to take before you explore

Pay down the loan balance if you can. The less you owe, the lower the risk to the lender, and the better your rate will be. Even paying an extra $1,000 or $2,000 before you explore can move you into a better rate category. If you have the cash, this is often worth doing instead of refinancing right away.

Gather your documents. You will need your current loan paperwork (the lender will verify the balance), proof of income (a recent pay stub or tax return), proof of residence (a utility bill or lease), and your driver's license. Some lenders also ask for proof of insurance. Having these ready speeds up the process and shows the lender you are organized.

Check whether your current loan has a prepayment penalty. Some loans charge a fee if you pay off the balance early. If yours does, factor that fee into your refinance calculation — it might erase your savings. Your loan documents should say whether a penalty applies, or call your current lender and ask directly.

What to expect during the refinance process

Once you explore, the lender will verify your income, check your credit, and confirm the car's value (usually through an online database, not an in-person inspection). This process typically takes three to seven business days. Some online lenders are faster — they may give you a decision within 24 hours — but they often charge higher rates or fees to make up for the speed.

If you are approved, the new lender will pay off your old loan and send you new loan documents. You sign these, and your new monthly payment begins. The whole process from process to funding usually takes one to two weeks, though it can be longer if the lender needs more information from you.

During this time, keep making your current loan payments on schedule. Do not miss a payment while you are waiting for the refinance to close — that will tank your credit score and may cause the new lender to back out of the deal. Once the new loan funds, your old lender will receive the payoff and close your account.

Frequently Asked Questions

Can I refinance if I am underwater on my car loan?

Being underwater means you owe more than the car is worth. Most lenders will not refinance you in this situation because they have no collateral if you default. Some credit unions and specialized lenders will, but they charge much higher rates. Your best option is to pay down the balance until you owe less than the car's value, then refinance.

Will refinancing hurt my credit score?

Yes, but only temporarily. The hard inquiry lowers your score by a few points, and closing your old loan and opening a new one changes your credit mix slightly. These effects fade within a few months. Over time, a lower monthly payment can actually help your score if it lowers your debt-to-income ratio.

What if I have been denied for refinancing?

Denial usually means your credit score is too low, you owe too much relative to the car's value, or your income is too unstable. Wait a few months, pay down the balance if you can, and try again. Your score improves over time as old negative marks age off your report.

Should I refinance with my current lender or a new one?

Ask your current lender first — they may offer you a better rate than a new lender would, and they can often refinance you with a soft inquiry that does not hurt your score. If they will not work with you or their rate is high, shop around with at least two other lenders before deciding.
