Refinancing means replacing your current car loan with a new one, usually at a different interest rate or term length
When you refinance a car loan, you take out a new loan from a different lender (or sometimes the same lender) to pay off what you still owe on your existing loan. The new lender pays off your old loan in full, and you then make monthly payments to the new lender instead. The main reason people refinance is to lower their interest rate, which reduces the total amount they pay over the life of the loan.
Refinancing is different from trading in your car or selling it. You keep the same vehicle — the only thing that changes is who holds the loan and what terms you're paying under. The car itself stays in your name and remains your responsibility.
Key Takeaways
- Refinancing replaces your existing car loan with a new one, typically to find a lower interest rate or change your monthly payment amount.
- Your credit score, the amount you still owe, and how much time remains on your original loan all affect whether refinancing makes financial sense.
- The new lender pays off your old loan directly, so you don't have to manage two loans at once.
- Refinancing costs money upfront (title transfer fees, document fees) and takes one to two weeks to complete, so the interest savings need to outweigh these costs.
Why people refinance car loans
The most common reason is a lower interest rate. If your credit score has improved since you took out your original loan, or if market interest rates have dropped, you may may have access to for a better rate. Even a 1 or 2 percent difference in interest rate can save hundreds of dollars over the remaining life of the loan.
People also refinance to change their monthly payment. If you need a lower payment to fit a tighter budget, you can refinance into a longer loan term — though this means paying more interest overall. Conversely, if you want to pay off your car faster, you can refinance into a shorter term with higher monthly payments.
Some people refinance to remove a co-signer from the original loan. If someone co-signed your car loan and you now have strong enough credit to may have access to on your own, refinancing lets you take over the loan solo.
How to know if refinancing makes sense for you
Refinancing only saves money if the interest rate on the new loan is meaningfully lower than your current rate. A general rule is that refinancing makes sense if you can lower your rate by at least 1 percent and you have at least two years left on your loan. If you're already in the final year or two of payments, the savings may not justify the upfront costs.
Check your current loan documents to find out what interest rate you're paying and how much you still owe. Then get quotes from banks, credit unions, and online lenders to see what rate they would offer you. This is called a rate inquiry, and checking multiple lenders within a 14-day window counts as a single hard inquiry on your credit report, so it won't damage your score.
Calculate the total cost of refinancing — including title transfer fees (usually $50 to $200 depending on your state) and any document or processing fees the new lender charges. Subtract this from the total interest you'd save over the remaining loan term. If the savings exceed the costs, refinancing is worth considering.
What happens during the refinancing process
Once you've chosen a lender and been approved, the new lender handles most of the paperwork. They order a payoff quote from your current lender, which tells them the exact amount needed to close out your old loan. The new lender then pays that amount directly to your old lender, and your original loan is closed.
You'll sign new loan documents with the new lender that spell out the new interest rate, monthly payment, and loan term. The new lender will also handle the title transfer with your state's motor vehicle department. During this process, the lender holds the title as collateral — this is standard for car loans.
The entire process typically takes one to two weeks from approval to completion. During that time, you continue making payments to your old lender as usual. Once the refinance closes, you'll make your first payment to the new lender on whatever date they specify.
What affects whether you'll be approved to refinance
Lenders look at your credit score, income, and how much you still owe relative to the car's current value. If you owe more than the car is worth (called being "upside down" on the loan), some lenders won't refinance you, though others will. Your payment history on the current loan matters too — if you've missed payments or paid late, refinancing will be harder to get approved for.
The age and mileage of the car also play a role. Most lenders won't refinance vehicles older than 10 years or with more than 100,000 miles, though these thresholds vary by lender. A newer car with lower mileage is easier to refinance.
If your credit score has dropped since you took out the original loan, you may not may have access to for a better rate, which means refinancing won't help you. In that case, it's worth waiting until your credit improves before refinancing.
Costs and fees involved in refinancing
The main costs are state-level fees for transferring the title into the new lender's name. These vary by state but typically range from $50 to $200. Some lenders charge document preparation fees or processing fees, usually $50 to $150. A few lenders offer no-fee refinancing, though this is less common.
There are no prepayment penalties for paying off your old car loan early through refinancing — federal law prohibits lenders from charging you for this. However, if you've paid interest upfront (called precomputed interest), you won't get that back when you refinance.
Factor these costs into your savings calculation. If you're saving $2,000 in interest over the remaining loan term but paying $300 in refinancing fees, your net savings is $1,700.
Alternatives to refinancing
If refinancing doesn't make financial sense, you have other options. You can straightforward continue paying your current loan as scheduled. You can also make extra payments toward principal without refinancing — this shortens the loan term and reduces the total interest you pay, though it doesn't lower your monthly payment.
If you need a lower monthly payment but refinancing isn't available to you, some lenders will work with you to modify your existing loan, though this is less common than refinancing. Contact your current lender directly to ask if loan modification is an option.
Frequently Asked Questions
Will refinancing hurt my credit score?
Refinancing causes a small, temporary dip in your credit score because the new lender does a hard inquiry and you're opening a new account. This typically drops your score by 5 to 10 points and recovers within a few months. The benefit of a lower interest rate usually outweighs this temporary impact.
Can I refinance a car I'm still paying off?
Yes — in fact, you can only refinance a car loan while you still owe money on it. Once the loan is paid off, there's nothing left to refinance. You must own the car outright or have the lender's permission to refinance if they hold the title.
How long does refinancing take?
The process typically takes one to two weeks from the time you're approved until the new loan closes and your old loan is paid off. Some lenders can move faster, but two weeks is a reasonable timeline to expect.
What if I'm upside down on my car loan?
Being upside down means you owe more than the car is worth. Some lenders will still refinance you, but others won't. Those who do may charge a higher interest rate or require you to pay the difference out of pocket. Ask lenders directly about their policy on upside-down loans.
Can I refinance with the same lender?
Yes, some lenders allow you to refinance with them, though you'll typically get better rates by shopping around. Even if you stay with the same lender, you'll still need to sign new documents and pay state title transfer fees.
