What refinancing your car loan means and when it makes sense
Refinancing your car loan means taking out a new loan to pay off the old one. The new lender pays what you still owe, and you make payments to them instead of your original lender. You refinance when the new loan has better terms — usually a lower interest rate, a shorter payoff period, or both — that save you money over time.
The math is straightforward: if you owe $15,000 at 8% interest and you can refinance at 5%, you pay less in total interest. But refinancing costs money upfront (process fees, title transfer fees), so it only makes sense if the interest you save exceeds what you pay to switch. Most people break even within 6 to 12 months, which means refinancing is worth considering if you plan to keep the car that long.
You can refinance with a bank, credit union, or online lender. Credit unions often offer the lowest rates to members, but you do not have to refinance with your original lender — shopping around is how you find the best deal.
Key Takeaways
- Refinancing saves money only if the new interest rate is low enough to offset process and title fees, which typically takes 6 to 12 months to recover.
- Your credit score, the age of your car, and how much you still owe all affect what interest rate lenders will offer you.
- Credit unions usually offer lower rates than banks or online lenders, but you should get quotes from multiple sources to compare.
- Refinancing resets your loan term, so choosing a shorter payoff period saves more interest but raises your monthly payment.
- You can refinance multiple times if rates drop or your credit improves, but each refinance costs money and takes time to process.
How your credit score and car value affect refinancing rates
Lenders use your credit score to decide what interest rate to offer. A higher score gets a lower rate. If your credit has improved since you took out the original loan — because you paid bills on time, paid down debt, or fixed errors on your credit report — you may now may have access to for a much better rate. Even a 1 or 2 percentage point drop saves hundreds of dollars over the life of the loan.
The age and mileage of your car also matter. Lenders want to know the car is worth enough to cover the loan if you stop paying. A newer car with lower mileage is easier to refinance because it holds its value. A car that is 10 years old or has over 150,000 miles may be harder to refinance, and some lenders will not touch it at all. You can check your car's approximate value on Kelley Blue Book or NADA Guides to see what lenders might be willing to finance.
How much you still owe compared to what the car is worth also affects your options. If you owe less than the car is worth, refinancing is straightforward. If you owe more than the car is worth (called being "underwater"), most lenders will not refinance you, or will charge a higher rate because the risk is higher.
Where to get refinancing quotes and what to compare
Start by contacting your bank or credit union. If you are a member of a credit union, ask about their auto refinance rates — credit unions typically offer 0.5 to 1.5 percentage points lower than banks. Then get quotes from at least two other lenders so you can compare. Online lenders like LendingClub, Lightstream, or SoFi, and banks like Wells Fargo or Chase, all offer auto refinancing.
When you request a quote, lenders will ask for your loan details (how much you owe, the original loan term, your current interest rate) and personal information (income, employment, credit history). A soft inquiry checks your credit without affecting your score. Most online lenders use soft inquiries for initial quotes. If you move forward, they will do a hard inquiry, which does show on your credit report but the impact is small and temporary.
Compare the interest rate, the loan term (how many months to pay it off), and the total fees. A lower rate is not always the best deal if the fees are high or the term is longer. Use an auto loan calculator to see the total amount you will pay under each option, including fees. The option with the lowest total cost is the one to choose.
How refinancing changes your monthly payment and payoff timeline
When you refinance, you choose a new loan term. You can keep the same payoff timeline as your original loan, shorten it to pay off faster, or lengthen it to lower your monthly payment. Each choice has a trade-off.
If you refinance at a lower rate and keep the same term, your monthly payment drops and you pay less interest overall. If you shorten the term (say, from 60 months to 48 months), your payment stays about the same or goes down slightly, but you pay off the car faster and save more on interest. If you lengthen the term to lower your payment, you pay more interest in the end, which defeats the purpose of refinancing — avoid this unless you need the payment relief right now.
The refinancing process itself takes 3 to 7 business days from approval to funding. During that time, you keep making payments to your original lender. Once the new lender funds the loan, they pay off the old one, and your next payment goes to the new lender. You will receive new loan documents and a new payment schedule in the mail.
Fees and costs you will encounter when refinancing
Refinancing is not free. Common costs include an process fee (typically $0 to $100), a loan origination fee (usually 1 to 2% of the loan amount), and a title transfer or administrative fee ($50 to $200, depending on your state). Some lenders advertise "no fees," but they often build the cost into a slightly higher interest rate instead.
Your original lender may also charge a prepayment penalty if you pay off the loan early. Some states limit or ban prepayment penalties, but others allow them. Check your original loan documents or call your lender to ask. If there is a penalty, factor it into your decision — it might be $200 to $500, which changes whether refinancing is worth it.
Add up all the fees and compare them to how much interest you will save. If you will save $1,500 in interest but pay $400 in fees, your net savings is $1,100. If you will only save $300 in interest, refinancing does not make financial sense.
When refinancing does not work or is not worth it
Refinancing is not the right move in every situation. If you are underwater on your loan (you owe more than the car is worth), most lenders will decline you. Some credit unions and banks will refinance an underwater loan if your credit is strong, but they will charge a higher rate to cover the extra risk. In that case, refinancing might not save you money.
If you are planning to sell or trade in the car within the next year, refinancing probably is not worth it. The fees and processing time mean you will not break even before you get rid of the car. If you are close to paying off the loan (less than 12 months left), refinancing also rarely makes sense because there is not enough interest left to save.
If your credit score has not improved since you took out the original loan, or if you have missed payments recently, lenders may not offer you a better rate. In that case, refinancing will not help. Focus on paying on time and paying down other debts to improve your credit score, then revisit refinancing in 6 to 12 months.
how the process works and what documents you will need
Once you have chosen a lender, you will fill out an process online or in person. Have these documents ready: your driver's license, proof of income (recent pay stubs or tax returns), proof of residence (utility bill or lease), your current auto loan details (account number, payoff amount, interest rate), and your vehicle identification number (VIN). The VIN is on your registration or dashboard.
The lender will pull your credit report and verify your income and employment. If everything checks out, they will send you a loan estimate that shows the interest rate, monthly payment, total fees, and loan term. Read it carefully and ask questions about anything you do not understand. Once you sign and return the documents, the lender will order a title search and prepare to fund the loan.
The lender will contact your original lender to get the exact payoff amount and arrange payment. This is why you do not have to worry about a gap in coverage — the new lender handles the payoff on your behalf. You will receive confirmation once the old loan is paid off and the new one is active.
Frequently Asked Questions
Can I refinance if I have a bad credit score?
Yes, but you will likely be offered a higher interest rate than someone with good credit. If the rate is not significantly lower than your current rate, refinancing will not save you money. Some credit unions are more willing to work with lower credit scores than banks or online lenders, so it is worth asking.
How many times can I refinance my car loan?
There is no legal limit, but each refinance costs money and takes time. Most people refinance once or twice if rates drop or their credit improves. Refinancing more than twice in a few years can raise red flags with lenders and may hurt your credit score from multiple hard inquiries.
Will refinancing hurt my credit score?
A hard inquiry will lower your score by a few points temporarily, usually recovering within a few months. The act of refinancing itself — paying off one loan and opening another — does not hurt your score. In fact, if refinancing lowers your monthly payment and you use that money to pay down other debts, your credit score may improve over time.
What if my car is worth less than I owe on it?
Most lenders will not refinance an underwater loan. Some credit unions will if your credit is strong, but they charge a higher rate. Your best option is to keep making payments until you owe less than the car is worth, then refinance. In the meantime, focus on paying down the principal as fast as you can.
Can I refinance a car loan I just took out?
Yes, but it rarely makes sense. Most lenders charge a prepayment penalty if you pay off a loan within the first year, and refinancing fees will be high relative to the interest you save. Wait at least 6 to 12 months before refinancing so the math works in your favor.
