Refinancing a car means replacing your current auto loan with a new one, usually at a lower interest rate or with different terms
When you refinance, you take out a fresh loan from a bank, credit union, or online lender to pay off what you still owe on your existing car loan. The new lender pays off your old loan in full, and you then make monthly payments to the new lender instead. The goal is usually to lower your interest rate, reduce your monthly payment, shorten the loan term, or some combination of those.
The car itself stays yours throughout the process — you are not selling it or trading it in. You are straightforward changing who holds the debt and on what terms. This is different from trading in a car at a dealership, where you exchange the vehicle for credit toward a new purchase.
Key Takeaways
- Refinancing replaces your current auto loan with a new one, typically to find a lower interest rate or adjust your monthly payment.
- Your credit score, current interest rate, how much you still owe, and the car's age all affect whether refinancing makes financial sense.
- The refinancing process usually takes one to two weeks from process to funding, and you keep driving your car the entire time.
- Refinancing costs little or nothing upfront, but some lenders charge origination fees, and you may pay a small fee to release your old loan.
- Refinancing works best when your credit score has improved since you took out the original loan, or when interest rates have dropped overall.
Why people refinance and when it makes sense
The most common reason to refinance is a lower interest rate. If you took out your original loan with fair or poor credit, your rate might have been 8%, 10%, or higher. If your credit has since improved, you may now may have access to for a rate of 5% or 6%. Even a 1% or 2% drop saves hundreds of dollars over the life of the loan.
People also refinance to lower their monthly payment. If you are facing a temporary cash shortage or your budget has tightened, extending the loan term — say, from 48 months to 60 months — spreads the payments over more time. The trade-off is that you pay more interest overall, but your month-to-month cash flow improves.
Less commonly, someone refinances to shorten the loan term. If you received a bonus or inheritance and want to pay off the car faster, you can refinance into a shorter loan at a better rate, which accelerates your payoff date.
Refinancing rarely makes sense if your current rate is already low (below 4%), your loan has only a year or two left, or if your car is very old or has high mileage. Lenders are less willing to refinance older vehicles, and the savings may not justify the paperwork and time.
How your credit score and loan details affect refinancing
Lenders use your credit score to decide whether to refinance you and at what rate. A score of 660 or higher opens doors to most lenders; below 620, your options shrink and rates stay high. If your score has climbed since you took out the original loan, you are a stronger candidate for a better rate.
The amount you still owe matters too. If you are "underwater" — meaning you owe more than the car is worth — refinancing becomes harder. Most lenders want the loan amount to be no more than 125% of the car's current market value. You can check your car's value on Kelley Blue Book or NADA Guides.
How long you have been paying also affects your chances. Lenders prefer to refinance loans that are at least 6 to 12 months old, because they want to see that you have a track record of on-time payments. If you are only three months into a five-year loan, most lenders will turn you down.
The age and mileage of the car matter as well. Most lenders will not refinance cars older than 10 years or with more than 150,000 miles, though some credit unions are more flexible. A newer car with lower mileage is easier to refinance.
The step-by-step refinancing process
Start by checking your credit report and score. You can pull your credit report free once per year at AnnualCreditReport.com. Knowing your score helps you understand what rates you might may have access to for and whether refinancing is worth pursuing.
Next, shop around with at least three lenders — banks, credit unions, and online lenders all offer auto refinancing. Each will ask for basic information: your name, the car's year and mileage, your current loan balance, and your Social Security number. This triggers a hard inquiry on your credit, which temporarily lowers your score by a few points, but multiple inquiries within 14 days typically count as one for scoring purposes.
Once you receive offers, compare the interest rate, monthly payment, loan term, and any fees. Some lenders charge an origination fee (typically 0% to 1% of the loan amount), while others charge nothing upfront. Factor these into your total cost.
When you choose a lender and accept their offer, they handle most of the paperwork. They contact your current lender, request your loan payoff amount, and arrange to pay off the old loan. You sign documents electronically or in person, depending on the lender. The entire process usually takes 7 to 14 days from acceptance to funding.
Once the new lender funds the loan, your old lender releases the lien on your car title. You then make payments to the new lender. Some lenders allow you to make your first payment 30 to 45 days after funding, giving you a brief grace period.
Costs and fees involved in refinancing
Refinancing is generally inexpensive compared to other financial transactions. Many lenders charge no origination fee at all. Those that do typically charge between 0% and 1% of the loan amount — so on a $15,000 loan, that would be $0 to $150.
Your old lender may charge a payoff fee, usually $50 to $100, to close the loan early. Some lenders waive this; others do not. Ask your current lender before you refinance.
There are no government fees, title transfer fees, or registration costs associated with refinancing. The car's title stays in your name, and your registration does not change. If your new lender requires a new inspection or appraisal, they typically cover that cost.
To know your true cost, calculate the total interest you will pay under the new loan and compare it to what you would pay if you kept your current loan. If the new loan saves you $500 in interest but costs $100 in fees, your net savings is $400. Online auto refinance calculators can help you run these numbers.
When refinancing does not work or is not available
If your credit score is very low (below 580), few lenders will refinance you at all, and those that do will offer rates no better than your current one. In this case, refinancing is not an option — your best move is to focus on paying down the loan and rebuilding your credit.
If you are underwater on your loan, refinancing is difficult. Some credit unions and specialized lenders will refinance negative equity, but they charge higher rates to offset the risk. It is usually better to keep paying your current loan until you are no longer underwater.
If your car is very old, has very high mileage, or has been in an accident, lenders may decline to refinance regardless of your credit. In these cases, you are stuck with your current loan unless you pay it off early with cash.
If your current rate is already very low (3% or below), refinancing savings will be minimal. The time and effort may not be worth a savings of $20 or $30 per month.
Refinancing versus other ways to lower your car payment
Refinancing is not the only way to reduce what you owe. You can also make extra principal payments toward your current loan, which shortens the term and saves interest without changing lenders. This works well if you have a windfall but do not want to refinance.
Trading in your car at a dealership is another option if you want out of your current loan. The trade-in value is applied to a new car purchase, which pays off your old loan. However, this only works if you want a different vehicle, and dealership loans often carry higher rates than refinancing.
Selling your car privately and using the proceeds to pay off the loan is a third option. This works best if your car is worth more than you owe, and you do not need a vehicle when ready. You would then need to buy another car with cash or take out a new loan.
Refinancing is usually the simplest and cheapest option if your goal is to lower your payment or rate on the car you already own and plan to keep.
Frequently Asked Questions
Does refinancing hurt my credit score?
Refinancing causes a small, temporary dip in your credit score because the new lender pulls your credit report. This hard inquiry typically lowers your score by 5 to 10 points. However, the score usually recovers within a few months, and the long-term benefit of a lower interest rate often outweighs the short-term hit. Making on-time payments on the new loan will rebuild your score faster.
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, not the original purchase price. The new lender pays off your old loan in full, and you owe the new lender instead. You must still owe money on the car for refinancing to make sense.
What if my car has a lien on the title?
A lien straightforward means your current lender holds a legal claim on the car until the loan is paid off. When you refinance, the new lender replaces the old one on the lien. You do not need to do anything — the lenders handle the lien transfer as part of the refinancing process.
How long does refinancing take?
From process to funding usually takes 7 to 14 days. Some online lenders can move faster, sometimes in as little as 3 to 5 days. You can drive your car normally during this time. Your first payment to the new lender is typically due 30 to 45 days after funding.
Can I refinance if I am behind on my current car payment?
Most lenders will not refinance if you are currently behind or have missed payments in the last 12 months. You need to catch up on your current loan first. Once you have made several on-time payments in a row, you become a better candidate for refinancing.
