What happens when you refinance a car loan
Refinancing a car loan means taking out a new loan to pay off your existing one. The new lender pays your current lender in full, and you then make monthly payments to the new lender instead. The main reason people refinance is to get a lower interest rate, which reduces what you pay each month and over the life of the loan.
Your credit score, the age of your car, how much you still owe, and current market rates all affect what rate a new lender will offer you. If your credit has improved since you took out the original loan, or if overall rates have dropped, refinancing can save you real money. A lender will run a credit check and verify the car's value and your loan balance before making an offer.
Key Takeaways
- Refinancing works best when your credit score has improved or interest rates have fallen since you took out your original loan.
- You will need your current loan payoff amount, the car's current value, and proof of income to start the refinancing process.
- The break-even point — where your savings exceed the costs of refinancing — typically takes six months to two years depending on how much your rate drops.
- Refinancing resets your loan term, so choosing a longer term lowers your monthly payment but costs more in total interest.
- You can refinance through banks, credit unions, online lenders, or sometimes your current lender, and rates vary significantly between them.
When refinancing actually saves you money
Refinancing saves money only if your new interest rate is meaningfully lower than your current one. A drop of even 1 percent can save hundreds of dollars over the remaining life of the loan, but you also pay fees to refinance — typically $0 to $300 depending on the lender and your state. You need to calculate whether the monthly savings will cover those costs before the loan ends.
The other factor is how long you plan to keep the car. If you are selling or trading it in within a year, refinancing probably does not make sense because you will not stay in the loan long enough to recoup the costs. If you plan to drive the car for several more years, the math usually works in your favor if your new rate is at least 0.5 percent lower than your current rate.
Your credit score is the biggest driver of the rate you will be offered. If your score has risen 50 points or more since you took out the original loan, you are a strong candidate for refinancing. Lenders also look at your payment history — if you have made every payment on time, they see you as lower risk and offer better rates.
Documents and information you will need
Before you contact a lender, gather your current loan documents. You need the exact payoff amount (not just your monthly payment), which you can get by calling your current lender or checking your online account. You also need the vehicle identification number (VIN), which is on your registration and insurance documents, and the current market value of your car.
Have your proof of income ready — recent pay stubs or tax returns, depending on what the lender asks for. You will also need a government-issued ID and your Social Security number. If you are refinancing with a credit union, you may need to become a member first, which usually takes a few minutes online and costs nothing.
Some lenders let you start the process online and upload documents digitally. Others require you to visit in person or speak with a loan officer by phone. Either way, the process typically takes three to seven business days from process to funding, though some online lenders move faster.
How interest rates are set for refinance loans
The rate you are offered depends on several factors working together. Your credit score is weighted most heavily — borrowers with scores above 740 typically get the best rates, while scores below 620 may not may have access to at all or will receive much higher rates. The age and mileage of your car matter too; lenders are less willing to refinance cars older than 10 years or with more than 150,000 miles, because the car is worth less and may be less reliable.
How much you owe compared to what the car is worth also affects your rate. If you owe more than the car is worth (called being "upside down"), some lenders will not refinance you at all. Others will, but they charge a higher rate to cover the extra risk. Current market conditions and the lender's own cost of borrowing set the baseline rates they offer, which is why rates vary between banks, credit unions, and online lenders.
The loan term you choose — how many months you have to pay back the loan — also influences the rate. A shorter term (36 to 48 months) usually comes with a lower rate, while a longer term (60 to 72 months) carries a slightly higher rate but a lower monthly payment. This is a trade-off you control: lower monthly payment now, or lower total interest paid over time.
Where to get refinance quotes
Banks, credit unions, and online lenders all offer car loan refinancing. Banks typically have higher rates but may waive fees if you are already a customer. Credit unions usually offer the lowest rates if you are a member, and membership is often free or very cheap. Online lenders move quickly and let you compare rates without visiting a branch, but their rates vary widely depending on your credit profile.
You can also ask your current lender whether they refinance their own loans — some do, and they already have your information on file. Getting quotes from at least three different lenders takes an hour and gives you a real sense of what the market will offer you. Each lender will do a hard credit inquiry, which temporarily lowers your score by a few points, but multiple inquiries within 14 days usually count as a single inquiry for scoring purposes.
When comparing offers, look at the total interest you will pay, not just the monthly payment. A longer loan term looks attractive because the payment is lower, but you may pay thousands more in interest. Use a loan calculator to see the total cost under each offer before you decide.
What happens after you refinance
Once you sign the paperwork, the new lender sends money directly to your current lender to pay off the old loan in full. Your current lender then releases the lien on your car — the legal claim they held as security for the loan. You will receive a letter confirming the loan is paid off, and your title will be updated to show the new lender as the lienholder.
Your first payment to the new lender is usually due 30 to 45 days after the loan funds. During that time, make sure you do not miss a payment to your old lender, because the payoff may not process when ready. Once you receive confirmation that the old loan is paid off, you can stop making those payments.
If you refinance and your monthly payment drops, do not spend that extra money elsewhere — put it toward paying down the loan faster. Even an extra $50 per month can cut months off your loan term and save you hundreds in interest. If you refinance into a longer term to lower your payment, you are extending how long you owe money on the car, so be intentional about that choice.
Reasons refinancing might not work for you
If your credit score is below 620, most mainstream lenders will not refinance you, or will charge rates so high that refinancing makes no sense. If you are upside down on your loan by more than a few thousand dollars, refinancing becomes difficult because the car is not worth enough to cover what you owe. If you have only a few months left on your current loan, the savings from a lower rate will not be enough to justify the refinancing costs.
If you are planning to sell the car soon, refinancing locks you into a loan that extends beyond when you own the vehicle. You would have to pay off the remaining balance when you sell, which defeats the purpose of refinancing. If your current loan already has a very low rate — below 3 percent — the chances of finding a meaningfully lower rate are slim.
Frequently Asked Questions
Can I refinance a car I still owe money on?
Yes, that is the whole point of refinancing. The new lender pays off what you owe to your current lender, and you start making payments to the new lender. You must still own the car and have a valid title, but you can refinance as long as the car is worth at least what you owe on it.
How many times can I refinance the same car?
There is no legal limit, but each refinance involves a hard credit inquiry and costs, so doing it repeatedly in a short time does not make financial sense. Most people refinance once or twice over the life of a loan. If rates drop significantly again after you refinance, you could do it again, but wait at least six months to a year between refinances.
What if my car is worth less than what I owe?
Some lenders will refinance you anyway, but they charge a higher rate because they are taking on more risk. Others will not refinance you at all. Your best option is to contact lenders directly and ask — some specialize in upside-down loans, though the rates are higher. You could also wait until you have paid down the loan enough to be right-side-up.
Does refinancing hurt my credit score?
Refinancing causes a small, temporary dip in your credit score because of the hard inquiry and the new account. The dip is usually 5 to 10 points and recovers within a few months. The long-term benefit of a lower interest rate and lower monthly payment typically outweighs this temporary effect.
Can I refinance if I am behind on payments?
Most lenders will not refinance you if you are currently behind on your car loan. You need to bring your account current first. Some lenders may refinance you if you have only missed one payment and can show proof that you have caught up, but this varies by lender.
