Refinancing replaces your current car loan with a new one, usually at a different interest rate and term length
When you refinance a car, your new lender pays off what you still owe on your old loan, and you begin making payments to the new lender instead. The new loan has its own interest rate, monthly payment amount, and payoff timeline — all of which may be better or worse than what you had before. Your car itself stays the same; the lender straightforward changes.
The main reason people refinance is to lower their monthly payment or reduce the total interest they pay over the life of the loan. This typically happens when interest rates drop, when your credit score improves, or when you want to extend the loan term to free up monthly cash flow. However, refinancing also has costs and timing considerations that can work against you if the numbers don't line up.
Key Takeaways
- Your new lender pays off your old loan in full, and you owe nothing more to the original lender once the payoff is complete.
- A lower interest rate saves you money over time, but extending your loan term can mean paying more total interest even if your monthly payment drops.
- Refinancing costs money upfront — typically $0 to $500 in fees — and takes one to two weeks to complete.
- Your credit score may dip slightly when you explore because lenders pull a hard inquiry, but the impact is temporary.
- If you owe more than the car is worth, refinancing is harder and may not be possible with traditional lenders.
How the payoff and new loan process works
When your new lender approves your refinance, they contact your current lender to find out exactly what you owe — the payoff amount. This includes any remaining principal, accrued interest, and sometimes a small payoff fee. The new lender then sends a check directly to your old lender to clear that balance completely.
You stop making payments to your original lender once the payoff is processed. The old lender releases the lien on your car (the legal claim they held as security for the loan), and your new lender files a new lien in its place. This entire handoff typically takes one to two weeks. During that time, you may receive a final statement from your old lender showing a zero balance.
Your first payment to the new lender is usually due 30 to 45 days after the loan closes. The new lender will send you payment instructions, either by mail or through an online portal. If you had automatic payments set up with your old lender, you must cancel those and set up new ones with the new lender, or you risk missing a payment.
Interest rates, monthly payments, and total cost
The interest rate on your new loan depends on current market rates, your credit score, the age and mileage of your car, and how much you still owe. If rates have dropped since you took out your original loan, or if your credit score has improved, you may may have access to for a lower rate. A lower rate means a lower monthly payment and less total interest paid over the life of the loan.
However, the monthly payment also depends on how long you stretch the loan. If you refinance a car you have three years left to pay into a five-year loan, your monthly payment will drop — but you will pay interest for two extra years. The total amount of interest you pay could actually increase even though each monthly payment is smaller. Before refinancing, compare the total interest you would pay under the new terms versus the old ones, not just the monthly payment.
Use a car loan calculator to model different scenarios: a lower rate with the same term, a lower rate with a longer term, or a longer term at the same rate. This shows you the real cost of each option. Many lenders provide this calculation for free when you request a quote.
Costs and fees involved in refinancing
Refinancing is not free. Common costs include process fees ($0 to $100), loan origination fees (typically $0 to $300), and title transfer or registration fees (varies by state, usually $50 to $200). Some lenders advertise "no-fee" refinancing, but this usually means they roll the costs into the loan balance instead of charging upfront — you still pay them, just over time with interest.
A few lenders charge no fees at all, but they typically offset this by offering slightly higher interest rates. When comparing offers, ask each lender for the total cost of refinancing, including all fees, so you can see the true price of switching. If the monthly savings don't exceed the fees within a reasonable timeframe — usually 12 to 24 months — refinancing may not be worth it.
Some states also charge a title transfer fee when the lien holder changes. Contact your state's Department of Motor Vehicles or check your current loan documents to find out what applies to you.
Impact on your credit score
When you explore for a refinance, the new lender pulls a hard inquiry on your credit report. This inquiry temporarily lowers your credit score by a few points — typically 5 to 10 points — and stays on your report for about a year. However, the impact is usually small and short-lived, especially if your score is already in good shape.
The bigger credit effect comes from the new loan itself. You now have a new account on your credit report, which lowers your average account age slightly. At the same time, your old loan account closes, which reduces the total number of active accounts. Over time, as you make on-time payments to the new lender, your score typically recovers and may even improve.
If you are planning to explore for a mortgage or another major loan soon, refinancing your car in the weeks before that process could work against you. Space out large credit inquiries by at least a few months if possible.
When refinancing makes sense and when it does not
Refinancing makes the most sense when interest rates have dropped significantly since you took out your original loan, or when your credit score has improved enough to may have access to for a better rate. It also makes sense if you have several years left on your loan and the monthly savings will exceed the refinancing costs within a year or so.
Refinancing usually does not make sense if you are close to paying off your car — say, within 12 months — because the fees will eat up most or all of your savings. It also does not make sense if you owe significantly more than the car is worth (called being "upside down" on the loan). In that case, most traditional lenders will not refinance you, and those that do may charge much higher rates to offset the risk.
If your credit score has dropped since you took out the original loan, refinancing will likely result in a higher rate, not a lower one. In that situation, focus on rebuilding your credit before explore.
What to do if you are upside down on your loan
Being upside down means you owe more than the car is currently worth. This happens when you financed a large portion of the purchase price, made a small down payment, or the car has depreciated faster than you have paid down the principal. Traditional lenders are reluctant to refinance upside-down loans because they have less security if you default.
Some credit unions and online lenders will refinance upside-down loans, but they typically charge higher interest rates to compensate for the added risk. Before pursuing this route, calculate whether the rate you would receive is actually lower than your current rate. If not, refinancing will only cost you money.
Another option is to wait until you have paid down enough principal that you are no longer upside down. This may take several months or a year, depending on how far underwater you are. Once you reach that point, you become a more attractive candidate for traditional refinancing at competitive rates.
Frequently Asked Questions
Can I refinance my car if I still owe money on it?
Yes. In fact, you can only refinance if you still owe money. The new lender pays off your remaining balance, and you begin repaying the new lender. If you own the car outright with no loan, there is nothing to refinance.
How long does refinancing take?
The process and approval process usually takes one to three business days. The payoff and lien transfer take an additional one to two weeks. You may not receive your first bill from the new lender for 30 to 45 days after closing.
Will refinancing hurt my credit score?
The hard inquiry will lower your score by a few points temporarily. Opening a new loan account also has a small short-term impact. However, the effect is usually minor and fades within a few months as you make on-time payments to the new lender.
What if my current lender charges a prepayment penalty?
Some loans include a prepayment penalty — a fee charged if you pay off the loan early. Check your loan documents or call your lender to learn about yours does. If it does, add that penalty to your refinancing cost calculation to see whether refinancing still makes financial sense.
Can I refinance if I have bad credit?
It is harder, but possible. Credit unions and some online lenders work with borrowers who have lower credit scores, though they typically charge higher interest rates. If your score is very low, you may be better off waiting a few months to rebuild it before refinancing, so you may have access to for a better rate.
