What refinancing a car loan means and when it makes sense
Refinancing a car loan means replacing your current loan with a new one from a different lender. The new lender pays off what you still owe on the old loan, and you start making payments to them instead. The main reason people refinance is to lower their monthly payment or reduce the total interest they pay over the life of the loan.
Refinancing makes the most sense when interest rates have dropped since you took out your original loan, or when your credit score has improved enough that lenders will offer you better terms. If you financed your car at 8% interest two years ago and rates are now at 5%, refinancing could save you hundreds of dollars. Similarly, if you had poor credit when you bought the car but have since paid down debt and built your score, you may now may have access to for a lower rate.
Refinancing does not erase what you owe — it just changes who you owe it to and potentially how much interest you pay. You will still owe the same amount until you pay it off, unless you refinance for a longer term, which lowers your monthly payment but increases total interest paid.
Key Takeaways
- Refinancing replaces your current car loan with a new one, usually from a bank, credit union, or online lender, and works best when interest rates drop or your credit improves.
- You need to know your current loan balance, your vehicle's value, and your credit score before you shop, because lenders will check all three.
- The refinancing process typically takes one to two weeks from process to funding, and your old lender is paid off automatically by the new lender.
- Refinancing costs little or nothing upfront, but some lenders charge origination fees, and you may owe a payoff penalty to your current lender depending on your loan contract.
- Extending your loan term lowers your monthly payment but means you pay more interest overall, so compare the total cost, not just the monthly number.
Check your current loan details and credit score before shopping
Before you contact any lender, gather three pieces of information: your current loan balance, your car's current market value, and your credit score. Your loan balance is on your monthly statement or you can call your current lender and ask. Your car's value you can find on Kelley Blue Book or NADA Guides by entering your vehicle's year, make, model, and mileage.
Your credit score matters because it determines what interest rate lenders will offer you. You can check your score free once per year at AnnualCreditReport.com, or use free tools from Credit Karma, Experian, or your bank. Most lenders pull your full credit report when you explore, but knowing your score beforehand tells you what range of rates to expect.
Lenders also care whether you owe more than the car is worth — called being "underwater" on the loan. If you owe $15,000 and the car is worth $12,000, some lenders will still refinance you, but you may have fewer options or higher rates. This is important to know before you start explore.
Where to shop for a refinance loan
You have three main sources for a refinance loan: your current lender, banks, and credit unions. Start by calling your current lender and asking what rate they would offer you to refinance. Many will match or beat outside offers to keep your business, and they already have your information on file, so the process is faster.
Banks and online lenders like LendingClub, Upgrade, and SoFi also offer car refinances. Banks typically have stricter credit requirements and may want you to have an existing account with them. Online lenders often move faster and have more flexible credit policies, but shop multiple lenders because rates vary widely even for the same borrower.
Credit unions often offer the lowest rates, but you must be a member to borrow from them. If you belong to one, ask about their refinance terms before going elsewhere. Some credit unions let you join through your employer, school, or community, so it is worth checking whether you have access to one.
What happens during the refinance process and approval
When you explore, the lender will ask for your personal information, your current loan details, and permission to pull your credit report. They will verify your income, usually by asking for recent pay stubs or tax returns. The whole process takes 15 to 30 minutes online or over the phone.
The lender then runs your credit and checks the car's value and your loan balance with your current lender. This process typically takes one to three business days. Once approved, the lender will send you a loan agreement showing the new interest rate, monthly payment, and loan term. Read this carefully — this is your chance to confirm the terms match what you expected before you sign.
After you sign, the new lender contacts your current lender and arranges to pay off your old loan. Your current lender sends the title to the new lender, and you start making payments to your new lender. The entire process from process to first payment usually takes one to two weeks.
Understand the costs and fees involved
Most car refinances have no upfront cost to you. However, some lenders charge an origination fee — typically 0% to 2% of the loan amount — which they deduct from your loan proceeds or add to your loan balance. A $15,000 loan with a 1% origination fee costs you $150, either paid upfront or rolled into the new loan.
Check your original loan contract to see whether you have a prepayment penalty. Some lenders charge a fee if you pay off the loan early, though this is less common than it used to be. If your contract has one, ask the new lender to calculate whether the savings from refinancing outweigh the penalty. Often they do, but not always.
You may also have to pay to transfer the vehicle title to the new lender, though many lenders handle this and cover the cost. Ask the lender upfront what fees, if any, you will owe before you sign the agreement.
Compare monthly payment against total interest paid
When you get loan offers, you will see a monthly payment and an interest rate. The temptation is to pick the lowest monthly payment, but that is not always the best choice. A lower payment usually means a longer loan term, which means you pay more interest overall.
For example, refinancing a $15,000 loan from 8% over 60 months to 5% over 60 months lowers your payment and saves you money. But refinancing from 8% over 60 months to 5% over 72 months lowers your payment even more — but you pay more total interest because you are borrowing for longer. Compare the total amount of interest you will pay, not just the monthly payment.
Most lenders provide a loan estimate that shows the total interest you will pay over the life of the loan. Ask for this from every lender you consider. If one lender offers a lower rate but a longer term, calculate the total cost yourself: multiply the monthly payment by the number of months, then subtract the loan amount. That difference is your total interest.
What to do if your current lender has a prepayment penalty
If your loan contract includes a prepayment penalty, you have three options. First, you can pay the penalty and refinance anyway if the interest savings are large enough to make it worthwhile. Second, you can wait until the penalty period ends — many penalties expire after a certain number of payments or years — and refinance then. Third, you can ask your new lender whether they will cover the penalty as part of the refinance deal, though this is uncommon.
To decide whether to pay the penalty, calculate your total savings. If refinancing saves you $2,000 in interest over the life of the loan but costs you a $500 penalty, you still come out $1,500 ahead. Your new lender can help you run these numbers when you explore.
Frequently Asked Questions
Will refinancing hurt my credit score?
Refinancing causes a small, temporary dip in your credit score because lenders pull your credit report when you explore. This dip usually recovers within a few months. However, refinancing can help your score long-term if it lowers your overall debt or improves your payment history going forward.
Can I refinance a car I still owe money on?
Yes, that is the whole point of refinancing — you refinance the amount you still owe. You do not need to own the car outright. The new lender pays off your current loan and takes a lien on the car until you pay off the new loan.
How many times can I refinance the same car?
There is no legal limit to how many times you can refinance, but lenders become more cautious if you refinance frequently. Each refinance pulls your credit and costs time and money, so it only makes sense to refinance when rates drop significantly or your credit improves substantially.
What if I owe more than the car is worth?
You can still refinance if you are underwater, but your options are more limited. Some lenders will refinance the full amount you owe, while others will only refinance up to the car's value and require you to pay the difference upfront. Credit unions are often more flexible on this than banks.
Does refinancing reset the loan term to the beginning?
Not necessarily. You can refinance for any term you choose — shorter, longer, or the same length as your original loan. A shorter term means higher monthly payments but less total interest. A longer term means lower payments but more total interest. Choose based on what you can afford and what saves you the most money overall.
