If you financed a car when your credit was weaker or rates were higher, you may be paying more than you need to. Auto loan refinancing replaces your current car loan with a new one, ideally at a lower interest rate. It can reduce your monthly payment, cut total interest, or both. But refinancing is not free money, and stretching your loan out can cost more over time. This guide explains when to refinance a car loan, what lenders look for, and how to complete the process.
How Auto Loan Refinancing Works
When you refinance, a new lender pays off your existing auto loan, and you begin making payments to the new lender under new terms. The new loan has its own interest rate, term, and payment. Your car remains the collateral, and the new lender is listed as the lienholder on the title.
You can refinance with banks, credit unions, and online lenders. Credit unions in particular often offer competitive auto refinance rates to members.
When Refinancing Makes Sense
Your Credit Has Improved
If your credit score has risen since you bought the car, perhaps because you have made on-time payments or paid down credit cards, you may qualify for a meaningfully lower rate.
Market Rates Have Dropped
When overall interest rates decline, new auto loans become cheaper, and refinancing can lock in a lower rate.
You Accepted Dealer Financing Without Shopping
Dealer-arranged financing may include a markup over the rate the lender would have offered. Refinancing with a lender you choose can remove that markup.
You Need a Lower Payment
If your budget has tightened, a longer term can lower your payment. This can provide relief, but it typically increases total interest, so treat it as a trade-off.
You Want to Remove or Add a Co-Borrower
Refinancing can let you take a co-borrower off the loan, for example after a divorce, or add one to qualify for a better rate.
When Refinancing May Not Help
- Your loan is almost paid off. Most interest on an auto loan is paid in the early years, so late refinancing saves little.
- You owe more than the car is worth. Lenders may decline or charge higher rates if you are upside down on your car loan.
- Your car is old or has high mileage. Many lenders set limits on vehicle age, often around 10 years, and mileage, often around 100,000 to 150,000 miles.
- Your current loan has a prepayment penalty. Check your contract; such penalties are less common but still exist.
- Your credit has worsened. A lower score may mean a higher rate than you have now.
Auto Refinance Requirements
| Requirement | Typical lender expectation |
|---|---|
| Credit score | Many lenders accept the low 600s; best rates go to roughly 700+ |
| Loan-to-value | Often up to about 125% of the car’s value, though stricter lenders cap lower |
| Vehicle age and mileage | Often 10 years or newer and under about 125,000 miles |
| Minimum loan balance | Commonly around $3,000 to $7,500 |
| Income | Verifiable income sufficient to cover payments |
| Payment history | On-time payments on the current loan, often for at least six months |
These are general patterns; each lender sets its own rules.
Costs to Watch
Auto refinancing usually costs less than mortgage refinancing, but there can still be fees:
- Title transfer and lien recording fees: charged by your state’s motor vehicle agency, often modest.
- Origination or application fees: some lenders charge them, many do not.
- Prepayment penalty on your current loan: if applicable.
- Add-on products: extended warranties or GAP insurance tied to your old loan may need to be canceled and refunded, or purchased again.
GAP Insurance
If your original loan included guaranteed asset protection (GAP) coverage, it may not transfer to the new loan. You may be entitled to a prorated refund on the old policy. If you still owe more than the car is worth, consider replacing GAP coverage, often available more cheaply through your auto insurer or credit union.
Calculating Your Savings
Compare the total remaining cost of your current loan with the total cost of the new loan.
Example: You owe $20,000 with 48 months left at a high rate. A credit union offers a lower rate for 48 months. The new monthly payment is lower, and because the term is the same, you also pay less total interest. If you instead chose 72 months, the payment would drop further, but you might pay as much or more total interest, and you would be making payments on an older car for two more years.
The rule of thumb is simple: keep the same or a shorter term if you can afford it, and use the lower rate to save on interest.
Step-by-Step: How to Refinance a Car Loan
- Gather loan details. Find your current lender, payoff amount, interest rate, and remaining term.
- Check your credit. Review your reports for errors and know your score.
- Estimate your car’s value. Use pricing guides to see whether you have equity.
- Prequalify with multiple lenders. Many lenders offer prequalification with a soft credit pull.
- Compare offers. Look at APR, term, fees, and total cost.
- Apply. Provide your driver’s license, proof of income, proof of insurance, vehicle information including VIN and mileage, and your current loan details.
- Sign and finalize. The new lender pays off your old loan. Keep making payments on your old loan until you confirm the payoff is complete.
- Update the title. The new lender typically handles lien changes with your state’s motor vehicle agency.
How Refinancing Affects Your Credit
Applying for a refinance results in a hard inquiry, which may lower your score slightly for a short time. Credit scoring models generally treat multiple auto loan inquiries within a short window, typically 14 to 45 days, as a single inquiry, so shop efficiently. Opening a new account and closing the old one can also affect average account age, but steady on-time payments help your credit over time.
Being Upside Down on Your Car Loan
If you owe more than the vehicle is worth, you have negative equity. Options include paying down the balance before refinancing, finding a lender with higher loan-to-value limits, or waiting until your balance falls. Avoid rolling negative equity into a new car purchase, which compounds the problem.
Alternatives to Refinancing
- Ask your current lender for help. Some lenders offer payment deferrals or modifications during hardship.
- Make extra principal payments. If your goal is to save interest, paying extra can achieve it without a new loan.
- Sell or trade down. If payments are unaffordable, a cheaper vehicle may be the long-term solution.
Questions to Ask Before You Sign
- Is the rate fixed for the full term?
- Are there origination, application, or document fees?
- Is there a prepayment penalty on the new loan?
- How long until my old loan is paid off, and what if a payment comes due during the transition?
- Will the lender handle the title and lien paperwork?

Frequently Asked Questions
How soon can I refinance a car loan?
There is no universal waiting period, but many lenders prefer that you have made at least six months of on-time payments and that the title has been transferred and registered in your name.
Can I refinance a car loan with bad credit?
It is possible, especially if your credit has improved since you took the original loan. Credit unions and lenders focused on subprime borrowers may work with lower scores.
Does refinancing a car loan hurt my credit?
It can cause a small, temporary dip due to the hard inquiry and new account. Over time, consistent payments can help your credit.
Can I refinance with the same lender?
Some lenders allow it, but many do not refinance their own loans. Shopping several lenders usually gets better results.
Is it worth refinancing to save a small amount each month?
Calculate total savings after fees. If the savings are small and you have little time left on the loan, refinancing may not be worth the effort.
