What refinancing a car loan means
Refinancing a car loan means taking out a new loan to pay off the old one. You keep the same car, but you replace your current lender and loan terms with a different lender and new terms. The new lender pays off what you still owe on the original loan, and you then make payments to the new lender instead.
The goal is usually to lower your monthly payment, reduce the interest rate, shorten the loan term, or some combination of those. Whether refinancing makes financial sense depends on your current loan terms, your credit score now versus when you first borrowed, current market interest rates, and how much you still owe on the car.
Key Takeaways
- Refinancing replaces your current auto loan with a new one from a different lender, and the new lender pays off your old balance in full.
- A lower interest rate is the main reason to refinance, but you only save money if the new rate is meaningfully lower than your current rate and you keep the car long enough to recoup any fees.
- Your credit score, the age and mileage of your vehicle, and how much you still owe all affect whether lenders will refinance and what rate they will offer.
- Refinancing typically involves a hard credit inquiry, which temporarily lowers your credit score by a few points, and may include fees ranging from zero to several hundred dollars depending on the lender.
- The break-even point—when your monthly savings equal the cost of refinancing—usually takes three to six months, so refinancing makes the most sense if you plan to keep the car for at least that long.
When refinancing makes financial sense
Refinancing saves you money only when the interest rate on the new loan is lower than your current rate. The difference needs to be large enough to offset any fees the new lender charges and to make up for the time you spend in the refinancing process. A drop of one percentage point or more is usually worth exploring; a drop of half a percentage point or less rarely justifies the effort.
Your credit score is the biggest factor in whether you will get a better rate. If your score has improved since you took out the original loan—because you have paid bills on time, paid down other debt, or corrected errors on your credit report—you are a better candidate for refinancing. Conversely, if your score has dropped, refinancing will not help you.
The age and mileage of your car also matter. Most lenders will not refinance vehicles older than seven to ten years or with more than 100,000 to 150,000 miles, depending on the lender. If your car is relatively new and has low mileage, you have more options.
How much you still owe versus what the car is worth
Lenders care about the gap between what you owe and what the car is worth. If you owe $15,000 on a car worth $18,000, you have positive equity and refinancing is straightforward. If you owe $18,000 on a car worth $15,000, you are underwater, and many lenders will not refinance you at all. Some will, but only at a higher interest rate to cover their risk.
You can check your car's current value using resources like Kelley Blue Book or NADA Guides. These sites ask for your vehicle's year, make, model, mileage, and condition, and return an estimated market value. Use that estimate when you contact lenders to discuss refinancing.
The refinancing process and timeline
The process typically starts with getting quotes from multiple lenders. Banks, credit unions, and online lenders all offer auto refinancing. You provide basic information about yourself and the car—the vehicle identification number (VIN), current loan balance, and current interest rate—and the lender runs a hard credit inquiry to determine what rate they can offer you.
A hard inquiry temporarily lowers your credit score by a few points, usually three to five points per inquiry. However, multiple inquiries for the same type of loan (auto refinancing) within a short window—typically 14 to 45 days, depending on the credit scoring model—count as a single inquiry. This means you can shop around without multiplying the damage to your score.
Once you choose a lender and accept their offer, they handle the paperwork with your current lender. The new lender pays off your old loan in full, and you sign documents for the new loan. The entire process from process to funding usually takes five to ten business days, though some lenders are faster.
Fees and costs to watch for
Some lenders charge no refinancing fees at all. Others charge an origination fee (typically one to three percent of the loan amount), a processing fee, or both. A few charge a prepayment penalty if you pay off the old loan early, though federal law limits these on most consumer auto loans.
Before you commit, ask the lender for the total cost of refinancing in dollars, not just percentages. If the new loan has a $300 origination fee and your monthly payment drops by $40, you break even in about eight months. If the fee is $800 and the payment drops by $30, you break even in 27 months—a much longer wait.
Some states and lenders also charge title transfer fees or registration fees when you refinance. Ask about these upfront so there are no surprises at closing.
Comparing loan terms: shorter versus lower payment
When you refinance, you can choose a new loan term. You might refinance into a shorter term (say, from 60 months to 48 months) to pay off the car faster and pay less interest overall. Or you might refinance into a longer term to lower your monthly payment, even if you pay more interest in total.
A shorter term means higher monthly payments but less total interest paid. A longer term means lower monthly payments but more total interest paid. The math depends on the interest rate you get and how long you plan to keep the car. If you are refinancing to lower your payment because money is tight, a longer term might be necessary—but understand that you are paying more interest to get there.
Use a loan calculator to compare scenarios. Enter your current loan balance, the new interest rate you have been offered, and different term lengths to see how the monthly payment and total interest change. This helps you decide whether a lower payment or a shorter term matters more to your situation.
When refinancing is not a good idea
Refinancing does not make sense if you are underwater on your loan and cannot find a lender willing to refinance. It also does not make sense if you plan to sell or trade in the car within the next few months, because you will not have time to recoup the refinancing costs through lower payments.
If your credit score has dropped significantly since you took out the original loan, you may not may have access to for a better rate. In that case, refinancing will not help and may actually cost you more. Similarly, if interest rates have risen since you borrowed, the new rate may not be lower than what you currently have.
Refinancing also does not help if you are behind on your current loan payments. Most lenders require that you be current (no missed or late payments in the last 60 to 90 days) before they will refinance. If you are struggling to make payments, contact your current lender about a loan modification or deferment instead.
Frequently Asked Questions
How many times can I refinance the same car?
There is no legal limit on how many times you can refinance. However, each refinance involves a hard credit inquiry and potentially fees, so refinancing multiple times in a short period can cost you more than you save. Most people refinance zero to two times over the life of a car loan.
Will refinancing hurt my credit score?
Refinancing causes a temporary dip in your credit score due to the hard inquiry and the new account on your credit report. The dip is usually small (three to five points) and recovers within a few months. The long-term impact is often positive if refinancing lowers your overall debt or improves your payment history.
Can I refinance if I have a loan from a buy-here-pay-here dealer?
Buy-here-pay-here loans are harder to refinance because they are typically high-risk loans with very high interest rates. Traditional lenders and credit unions may not refinance them. Your best option is to contact your current lender and ask whether they allow payoff without penalty, then explore whether a bank or credit union will refinance based on the car's value alone.
What if my current lender charges a prepayment penalty?
Federal law limits prepayment penalties on most auto loans to one percent of the remaining balance or three months of interest, whichever is less. Some lenders charge no penalty at all. Ask your current lender what the penalty is before you refinance, and factor it into your break-even calculation.
Do I need to have the car paid off to refinance?
No. You refinance while you still owe money on the car. The new lender pays off the remaining balance on your old loan and issues you a new loan for that amount. You never own the car outright during this process unless you choose to pay off the old loan yourself first.
