Refinancing an Auto Loan When Your Credit Score Is Low

What refinancing means and why poor credit makes it harder

Refinancing means replacing your current auto loan with a new one, usually from a different lender. The new lender pays off what you still owe, and you make payments to them instead. People refinance to lower their monthly payment, reduce the interest rate, or shorten the loan term.

With poor credit, refinancing becomes harder because lenders see you as higher risk. A low credit score — typically below 620 — signals that you have missed payments, carried high debt, or had other financial problems in the past. Lenders respond by charging higher interest rates, requiring a larger down payment, or simply declining to refinance you at all.

That said, refinancing with poor credit is not impossible. Your options narrow, but they exist. The key is understanding which lenders will work with you, what they will charge, and whether refinancing actually saves you money given those costs.

Key Takeaways

• Credit unions and subprime lenders will refinance auto loans for people with poor credit, while traditional banks rarely will.
• Refinancing with poor credit usually means paying a higher interest rate than your current loan, so you must calculate whether the new payment is actually lower.
• Your current vehicle's value matters: if you owe more than it is worth, most lenders will decline to refinance.
• Improving your credit score before refinancing — even by 20 or 30 points — can meaningfully lower the interest rate a lender offers you.
• Some lenders charge origination fees or prepayment penalties that can erase any savings from a lower payment.

Where to look for a refinance lender when your credit is poor

Traditional banks almost never refinance auto loans for borrowers with poor credit. Start instead with credit unions, which are member-owned financial institutions that often have more flexible lending standards than banks. You do not need to work for a specific employer or live in a specific place to join many credit unions — some are open to anyone in a geographic area, and others let you join if you have a family member who is already a member. Call ahead to ask if they refinance auto loans and what credit score range they work with.

Subprime lenders specialize in loans for people with poor credit. They charge higher interest rates than prime lenders, but they will consider your application when banks and credit unions will not. Online lenders like LendingClub, Upgrade, and Elevate offer auto refinancing to borrowers with lower scores. Compare offers from at least three lenders before accepting one, because rates vary widely even within the subprime market.

Your current lender may also refinance you. Call them and ask whether they offer rate reductions for existing customers with poor credit. Some do, especially if you have made on-time payments since taking out the original loan.

How to calculate whether refinancing actually saves you money

A lower monthly payment does not always mean refinancing is worth it. You must account for the total cost of the new loan, including interest and any fees the lender charges.

Gather these numbers: your current loan's remaining balance, current interest rate, and months left to pay; the new lender's interest rate; any origination fee, application fee, or prepayment penalty; and how many months the new loan would run. Use an auto loan calculator (available free online from Bankrate, NerdWallet, or your bank's website) to compare the total interest you will pay under both scenarios.

Example: You owe $12,000 on a loan at 9% interest with 48 months left. A subprime lender offers to refinance at 14% interest with a $300 origination fee and a 60-month term. Your current total interest cost is roughly $2,160. Under the new loan, you would pay roughly $4,800 in interest plus the $300 fee. Even though your monthly payment drops, you pay $2,940 more overall. In this case, refinancing loses money.

If the new lender's rate is lower than your current rate, the math is more likely to work in your favor — but always run the numbers before signing.

What lenders will ask about your vehicle and loan history

Lenders will want to know your vehicle's current market value, which they determine using tools like Kelley Blue Book or NADA Guides. If you owe more than the car is worth — called being "underwater" on the loan — most lenders will decline to refinance. Some will refinance if you can pay the difference upfront, but that defeats the purpose for most borrowers.

They will also pull your credit report and ask about your payment history on the current loan. If you have missed payments in the last 12 months, refinancing becomes much harder. Lenders want to see at least 6 to 12 months of on-time payments before they will consider you. If you are currently behind on payments, focus on catching up before applying to refinance.

You will need to provide proof of income, a driver's license, and proof of insurance. Some lenders also verify employment by contacting your employer directly.

How to improve your chances before you apply

If you are not in a rush, spending a few months improving your credit score before refinancing can lower the interest rate you are offered. Pay all bills on time, even if you can only pay the minimum. Reduce the balance on credit cards if possible — lenders look at how much of your available credit you are using. Dispute any errors on your credit report by contacting the three major bureaus (Equifax, Experian, TransUnion) directly.

A 20 to 30-point improvement in your credit score can move you from one lender category to another and save you 1 to 2 percentage points on your interest rate. Over the life of a loan, that difference is substantial.

You can also ask a family member or friend with better credit to cosign the new loan. A cosigner does not have to make payments, but they are legally responsible if you do not, so lenders view them as insurance. This can lower the rate you are offered, though it puts the cosigner at risk.

Prepayment penalties and other costs that eat into savings

Before you sign a refinance agreement, read the fine print for prepayment penalties. Some lenders charge a fee if you pay off the loan early or refinance again. If your current loan has a prepayment penalty, factor that into your calculation — you will have to pay it when the new lender pays off the old loan.

Origination fees, application fees, and document preparation fees are common with subprime lenders. These are sometimes rolled into the loan amount (meaning you finance them), which increases the total you owe. Ask the lender for a complete list of all fees before you commit.

Some lenders also require you to carry gap insurance or specific types of auto insurance as a condition of refinancing. Verify what insurance your current policy includes and whether the new lender's requirements will cost you more.

When refinancing does not make sense

If you are within the last year of your loan, refinancing rarely makes financial sense. You have already paid most of the interest, and a new loan resets the clock. The fees and new interest charges will almost certainly outweigh any monthly savings.

If your vehicle is very old or has high mileage, lenders may decline to refinance regardless of your credit score. They want assurance that the car will last long enough for you to finish paying. If you are underwater on the loan and cannot pay the difference upfront, refinancing is not an option with most lenders.

If you are currently behind on payments or have missed payments in the last 6 to 12 months, focus on getting current before applying. Refinancing while delinquent will either be declined or offered at a rate so high that it does not help you.

Frequently Asked Questions

Will refinancing hurt my credit score?

Yes, but usually only temporarily. When you apply for refinancing, the lender pulls your credit report, which causes a small dip in your score. Once the new loan is in place and you make a few on-time payments, your score typically recovers. The long-term impact depends on whether refinancing lowers your overall debt and whether you make payments on time.

Can I refinance if I have a cosigner on my current loan?

Yes. The new lender will refinance the loan regardless of who is on the original note. However, if you want to remove the cosigner from the new loan, the new lender will evaluate your creditworthiness alone, which may result in a higher interest rate or a declined application.

What if I am underwater on my car loan?

Most lenders will not refinance if you owe more than the vehicle is worth. Some will refinance if you pay the difference upfront, or they may offer a loan for the full amount owed but at a higher interest rate. Your best option is to wait until the vehicle's value rises or you pay down the balance enough to be above water.

How long does the refinancing process take?

From application to funding typically takes 3 to 7 business days with online lenders and credit unions. Banks may take longer. Once the new lender funds the loan, they pay off your old lender directly, and you start making payments to the new lender.

Should I refinance if my interest rate is only slightly higher than before?

Not necessarily. Run the full calculation including all fees and the total interest you will pay over the life of the new loan. If the new rate is only 0.5 to 1 percentage point higher and the loan term is shorter, you may still come out ahead. If the rate is higher and the term is longer, you will almost certainly pay more overall.
