What refinancing a car loan means and when it makes sense
Refinancing a car 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. People refinance when interest rates have dropped since they got their original loan, when their credit score has improved, or when they want to change the length of the loan to lower their monthly payment.
The main reason to refinance is to lower your interest rate. If you originally borrowed at 8% and rates have fallen to 5%, refinancing could save you hundreds or thousands in interest over the life of the loan. A better credit score since you took out the original loan can also may have access to you for a lower rate now. Some people refinance to extend the loan term — stretching payments over more years lowers the monthly bill, though you pay more interest overall.
Refinancing does not make sense if you owe more than the car is worth, if you are very close to paying off the original loan, or if the new loan's fees and interest would cost more than you would save. It also takes time and involves a hard credit inquiry, which temporarily lowers your credit score by a few points.
Key Takeaways
- Refinancing replaces your current car loan with a new one, usually at a lower interest rate if your credit has improved or rates have dropped.
- You will need your current loan balance, the car's value, your credit report, and proof of income and insurance before you approach a lender.
- Banks, credit unions, and online lenders all offer car refinancing, and comparing offers from at least three takes an hour and can save thousands.
- The refinancing process typically takes one to two weeks from process to funding, and your old lender is paid off automatically by the new one.
- Extending your loan term lowers your monthly payment but increases the total interest you pay over the life of the loan.
Gather the documents and information you will need
Before you contact any lender, collect the paperwork that all of them will ask for. You need your current loan documents (or a statement from your lender showing the balance, interest rate, and remaining term), your car's title or registration, and proof of insurance. You will also need your driver's license, Social Security number, and recent pay stubs or tax returns to show income.
Pull your credit report from one of the three major bureaus — Equifax, Experian, or TransUnion — at annualcreditreport.com, which is free and does not lower your score. Knowing your credit score before you explore helps you understand what interest rate range you might receive. You will also need the car's current market value; use Kelley Blue Book, NADA Guides, or Edmunds to estimate what it is worth in your area and condition.
Finally, find out exactly how much you still owe on the current loan. Call your lender or log into your account online. This number matters because if you owe more than the car is worth, most lenders will not refinance you, or will only do so at a higher rate.
Compare offers from banks, credit unions, and online lenders
You have three main sources for a refinance loan: traditional banks, credit unions, and online lenders. Banks offer competitive rates if you have good credit and an established relationship with them. Credit unions often have lower rates than banks, especially if you are a member, but you have to join first — many credit unions let you join based on where you work, where you live, or membership in certain organizations. Online lenders move quickly and may work with lower credit scores, but their rates are often higher.
Contact at least three lenders and ask for a rate quote. Most will give you a preliminary rate without a hard credit pull, so you can compare without damaging your score. When you are ready to move forward with one lender, they will do a hard pull, which does lower your score slightly. Gather quotes within a short window — a few days — because multiple hard inquiries for the same type of loan (car refinancing) usually count as a single inquiry for scoring purposes.
Pay attention to the interest rate, the loan term they are offering, any fees (origination, process, or prepayment penalties), and whether the rate is fixed or variable. A fixed rate stays the same for the life of the loan; a variable rate can change. For car loans, fixed rates are standard and safer.
Understand how the refinancing process works
Once you choose a lender and they approve your process, they will order a title search to confirm you own the car and that there are no other liens against it. They will also order a vehicle inspection or valuation to confirm the car's condition and value. This usually takes a few days.
After approval, the new lender sends the payoff amount directly to your current lender and receives the title. You never handle the money — the old loan is closed and the new one begins. You will receive new loan documents and a payment schedule showing your new monthly payment, interest rate, and payoff date. Your first payment to the new lender is usually due 30 to 45 days after the loan funds.
The entire process from process to funding typically takes one to two weeks, though it can be faster with online lenders or slower if the title search uncovers issues. During this time, keep making payments to your old lender on schedule unless the new lender tells you to stop.
Decide whether to shorten or extend your loan term
When you refinance, you choose a new loan term — the number of years you have to pay it back. This is a key decision because it directly affects your monthly payment and the total interest you pay.
If you keep the same term as your original loan (for example, refinancing a 5-year loan into another 5-year loan), your monthly payment will drop if your new interest rate is lower. If you extend the term — say, refinancing a 5-year loan into a 7-year loan — your monthly payment drops even more, but you pay interest for two extra years. If you shorten the term — refinancing a 5-year loan into a 3-year loan — your monthly payment rises, but you pay off the car faster and pay less interest overall.
Calculate the total cost of each option before you decide. A lower monthly payment feels good now, but if it means paying thousands more in interest, it may not be the right choice for your situation. Many lenders' websites have calculators that show you the total interest paid under different terms.
Know what happens if you have negative equity
Negative equity means you owe more on the car than it is worth. If you owe $15,000 and the car is worth $12,000, you are $3,000 underwater. Most traditional lenders will not refinance a car with negative equity because they have no collateral if you stop paying.
Some credit unions and specialized lenders will refinance negative equity loans, but they charge a higher interest rate to offset the risk. A few will roll the negative equity into the new loan, meaning you borrow the extra $3,000 along with the car's value. This is expensive because you pay interest on money you do not owe on the car itself.
If you have negative equity, your best option is usually to wait until you have paid down the loan enough to owe less than the car is worth. You can also make a large down payment toward the current loan to reduce what you owe, then refinance once you have positive equity.
Avoid common mistakes during refinancing
Do not explore to too many lenders at once. Each process triggers a hard credit inquiry, and multiple inquiries in a short time can lower your score significantly. Stick to three to five lenders within a week or two.
Do not refinance if you are very close to paying off the original loan. If you have only six months left on a 5-year loan, refinancing into a new 5-year term means you are starting over and will pay years of additional interest. The math rarely works in your favor this close to the end.
Do not skip the fine print on fees. Some lenders charge origination fees, process fees, or prepayment penalties on the old loan. Add these to the interest rate when you calculate whether refinancing actually saves you money. A lower rate is not a savings if fees eat up the difference.
Do not assume your insurance will transfer automatically. Contact your insurance company once the new lender has the title and let them know the loan has changed. Some policies require updating the lienholder information.
Frequently Asked Questions
Will refinancing hurt my credit score?
Yes, but only temporarily. The hard credit inquiry lowers your score by a few points, usually 5 to 10. Your score recovers within a few months as you make on-time payments to the new lender. Multiple applications within a short window count as one inquiry for scoring purposes, so explore to several lenders within a week or two rather than spreading applications over months.
Can I refinance a car I still owe money on?
Yes, that is the whole point of refinancing. As long as you owe less than the car is worth, a lender will refinance the remaining balance. The new lender pays off your old loan in full, and you start fresh with them.
What if my car has high mileage or is older?
Most lenders have age and mileage limits — typically they will not refinance cars older than 10 to 15 years or with more than 150,000 to 200,000 miles. Some credit unions and online lenders are more flexible. Ask before you explore, because a rejected process counts as a hard inquiry and lowers your score.
How much money can I actually save by refinancing?
That depends on your current interest rate, your new rate, how much you still owe, and how long you keep the car. Use an online calculator with your actual numbers — your current balance, current rate, remaining term, and the new rate you have been quoted. The calculator will show you the total interest under both loans so you can see the difference.
Do I need to tell my current lender I am refinancing?
No. Your new lender handles all communication with your old lender and pays them off directly. You do not need to notify anyone. Keep making your regular payment to your old lender until the new loan funds and you receive confirmation that the old loan is closed.
