Yes, you can refinance a car loan, but lenders will check your credit score, income, and how much you still owe on the vehicle

Refinancing means replacing your current car loan with a new one, usually from a different lender. The new loan pays off the old one, and you start making payments to the new lender instead. People refinance to lower their monthly payment, reduce the interest rate, shorten the loan term, or change from a variable rate to a fixed rate.

Whether a lender will refinance your loan depends on three main things: your credit score, your current income, and the loan-to-value ratio (how much you owe compared to what the car is worth). Most lenders want your credit score to be at least 620, though better rates typically require a score of 700 or higher. You also need to prove you can afford the new payment, and the car itself must be worth enough to find the loan.

The process usually takes one to two weeks from process to funding. You will need your current loan documents, proof of income, and the vehicle's title. The new lender will order an appraisal or use market data to determine what your car is worth, then decide whether to refinance and at what rate.

Key Takeaways

  • Refinancing replaces your existing car loan with a new one, typically from a different lender, and you begin making payments to that new lender.
  • Lenders review your credit score, income, and the car's current value to decide whether to refinance and what interest rate to offer.
  • You cannot refinance if you owe more than the car is worth, a situation called being underwater on the loan.
  • The best time to refinance is when your credit score has improved since you took out the original loan, or when interest rates have dropped.
  • Your current lender has no say in whether you refinance; you can refinance with any lender at any time, as long as the new lender approves you.

What lenders check before approving a refinance

When you explore to refinance, the new lender runs a hard credit inquiry, which temporarily lowers your credit score by a few points. They pull your full credit report to see your payment history, any late payments, collections accounts, or bankruptcies. A single late payment on your car loan can disqualify you or result in a higher interest rate than your original loan.

Lenders also verify your income through recent pay stubs, tax returns, or bank statements. They want to confirm you earn enough to cover the new monthly payment plus your other debts. If your income has dropped since you took out the original loan, or if you have taken on significant new debt, refinancing becomes harder.

The third major factor is the car's value. Lenders order an appraisal or check market data through services like NADA Guides or Kelley Blue Book to determine what your vehicle is worth. They compare this to what you still owe. If you owe $15,000 on a car worth $12,000, you are underwater, and most lenders will not refinance. Some credit unions and banks will refinance underwater loans, but only for borrowers with strong credit and income.

When refinancing makes financial sense

Refinancing saves money when your new interest rate is lower than your current rate. If you originally borrowed at 8% and rates have dropped to 5%, refinancing could reduce your monthly payment or shorten your loan term. Even a 1% to 2% reduction can save hundreds of dollars over the life of the loan.

Refinancing also makes sense if your credit score has improved since you took out the original loan. If you had a lower score when you first borrowed, you may have paid a higher rate. Paying on time for 12 to 24 months typically raises your score enough to may have access to for better terms. Check your credit report before explore to understand what lenders will see.

Refinancing to shorten your loan term is another common reason. If you originally took a 72-month loan but have paid it down and want to pay it off faster, you can refinance into a 36-month or 48-month loan. Your monthly payment will be higher, but you will pay less interest overall and own the car sooner.

Refinancing usually does not make sense if you are near the end of your loan. If you have only 12 months of payments left, the interest you save will not offset the cost of the new loan. It also does not make sense if the new rate is only slightly lower than your current rate, because closing costs and the process process eat into the savings.

The refinancing process and timeline

Start by gathering your current loan documents, recent pay stubs or tax returns, and proof of residence. You will also need the vehicle identification number (VIN) and current mileage. Contact banks, credit unions, and online lenders to get rate quotes. Most lenders offer pre-qualification, which does not require a hard credit pull and gives you an estimate of what rate you might receive.

Once you choose a lender and formally explore, they order an appraisal or use automated valuation to determine the car's worth. This step typically takes three to five business days. After the appraisal comes back, the lender underwrites your process, meaning they review all your documents and make a final decision. Underwriting usually takes two to three business days.

If approved, the lender prepares loan documents for you to sign. You sign these documents, and the lender sends the payoff amount to your current lender. Your current lender releases the title, and the new lender funds the loan. The entire process from process to funding usually takes seven to fourteen business days, though it can be faster with credit unions or slower if the appraisal reveals issues.

You do not need to contact your current lender before explore to refinance. The new lender handles all communication with your old lender. However, you should continue making payments to your current lender until the new loan funds and you receive confirmation that the old loan has been paid off.

Costs and fees associated with refinancing

Refinancing is not free. Most lenders charge an process fee (typically $75 to $150), an appraisal fee ($100 to $200), and a documentation or processing fee ($50 to $300). Some lenders bundle these into the loan itself, meaning you pay them over time with interest. Others require you to pay them upfront.

A few lenders advertise no-fee refinancing, but this usually means they charge a slightly higher interest rate to offset their costs. Compare the total interest you will pay over the life of the loan, not just the interest rate itself. A loan with a lower rate but higher fees might cost more than a loan with a slightly higher rate and no fees.

Your state or local government may also charge a title transfer fee, which varies widely. Some states charge $10 to $25; others charge $100 or more. Ask the lender what title fees explore in your state before you commit.

Reasons a lender might deny your refinance request

The most common reason for denial is being underwater on the loan. If you owe more than the car is worth, most mainstream lenders will not refinance. Your options are then limited to credit unions, which sometimes refinance underwater loans for members with good credit, or waiting until you have paid down the loan enough to reach the car's value.

A low credit score is another frequent reason for denial. If your score is below 620, most lenders will decline. If you have recent late payments, collections, or a recent bankruptcy, lenders view you as high-risk. In these cases, you may need to wait six to twelve months, continue paying on time, and rebuild your credit before reapplying.

High mileage or a vehicle in poor condition can also lead to denial. If your car has over 150,000 miles or significant mechanical issues, lenders may consider it too risky to find a loan. Some lenders have strict mileage limits; others do not. Ask about mileage requirements before explore.

Insufficient income is a third reason. If your debt-to-income ratio is too high—meaning your total monthly debt payments are more than 40% to 50% of your gross monthly income—lenders will decline. This is especially true if you have taken on new debt since your original loan.

Alternatives to refinancing if you cannot may have access to

If you are denied for refinancing, you have other options. If your current lender offers loan modification, you can ask them to adjust your terms without refinancing. Some lenders will lower your rate, extend your term, or change other conditions if you have been a good customer. This is less common than it used to be, but it is worth asking.

If your credit score is the barrier, focus on paying all bills on time for the next 6 to 12 months. Each on-time payment raises your score. Paying down other debts also helps, because it lowers your debt-to-income ratio. Once your score improves, reapply with the same lender or shop around for better offers.

If you are underwater on the loan, you can continue making payments until the car's value rises or you pay down the principal enough to reach the car's value. In the meantime, avoid taking on new debt, which will make refinancing even harder. Some people also trade in an underwater car and roll the negative equity into a new car loan, though this is expensive and usually not recommended.

If the car itself is the problem—too old, too many miles—you might consider selling it and buying a used car with cash or a smaller loan. This is a bigger decision, but it can be cheaper than keeping a car that is difficult to refinance.

Frequently Asked Questions

Does refinancing hurt my credit score?

Yes, but only temporarily. The hard credit inquiry lowers your score by a few points, usually five to ten. This dip fades within a few months as you make on-time payments on the new loan. Shopping around with multiple lenders within a two-week window counts as a single inquiry, so get quotes from several places without worrying about multiple hits.

Can I refinance a car I am still paying off?

Yes. You can refinance at any time, as long as you owe less than or equal to what the car is worth and you meet the lender's credit and income requirements. You do not have to wait until the loan is paid off. Many people refinance after one or two years of on-time payments, when their credit score has improved.

What if my car has a lien on it?

A lien means your current lender holds the title until you pay off the loan. This is normal. When you refinance, the new lender pays off the old lender and takes the lien. You never hold the title yourself during this process. The new lender handles all the paperwork with your old lender.

How much can I save by refinancing?

Savings depend on your current rate, the new rate, and how much you still owe. If you owe $20,000 at 8% and refinance to 5%, you could save $2,000 to $4,000 in interest over the remaining loan term, depending on how long you have left to pay. Use an online calculator to estimate your savings before explore.

Should I refinance if I only have one year left on my loan?

Usually not. The fees and closing costs typically outweigh the interest savings when you have less than 18 months remaining. Calculate your total savings (interest saved minus fees paid) before explore. If the number is negative, refinancing will cost you money.
