What refinancing a car loan means and how the rate changes
Refinancing a car means replacing your current loan with a new one, usually 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. The interest rate on your new loan can be lower, higher, or the same as your current rate — it depends on market conditions, your credit profile, and the lender you choose.
The reason people refinance is usually to lower their monthly payment or reduce the total interest they'll pay over the life of the loan. If interest rates have dropped since you took out your original loan, or if your credit score has improved, you may may have access to for a better rate. However, refinancing also has costs — process fees, title transfer fees, and sometimes prepayment penalties on your original loan — so the savings need to outweigh those expenses to make sense.
Key Takeaways
- Your new refinance rate depends on current market interest rates, your credit score, the age and mileage of your vehicle, and the lender's own pricing.
- Refinancing makes financial sense only if your new rate is low enough that the monthly savings cover the fees involved in switching loans.
- Banks, credit unions, and online lenders all offer car refinancing, and rates vary significantly between them — shopping multiple lenders is standard practice.
- Your original lender may charge a prepayment penalty for paying off the loan early, so check your loan documents before you refinance.
- The refinance process typically takes one to two weeks from process to funding, during which you continue making payments to your original lender.
What determines your refinance rate
Your credit score is the single largest factor in the rate you'll be offered. Lenders use your score to assess the risk of lending to you. A score above 750 typically qualifies for the best rates; a score between 650 and 750 will see higher rates; and a score below 650 may make refinancing difficult or expensive. If your credit has improved since you took out your original loan, refinancing can pay off.
The current market interest rate environment matters just as much. When the Federal Reserve raises or lowers its benchmark rate, banks adjust what they charge borrowers. If rates have fallen since you got your original loan, refinancing becomes attractive. If rates have risen, refinancing will likely cost you more, not less.
The age and mileage of your car also affect the rate. Lenders view newer cars with lower mileage as lower risk. A car that's five years old with 60,000 miles will may have access to for a better rate than a ten-year-old car with 120,000 miles. Some lenders have mileage caps — they won't refinance cars over 100,000 or 120,000 miles — so check before you explore.
The amount you still owe and how much equity you have in the car matter too. If you owe less than the car is worth, you're in a stronger position. If you're underwater — owing more than the car's value — some lenders will still refinance you, but at a higher rate or with stricter terms.
Where to get a car refinance and how rates compare
Banks, credit unions, and online lenders all offer car refinancing. Your original lender is one option, but they have no incentive to offer you a better rate, so they rarely do. Shopping at least three other lenders is standard practice and takes a few hours.
Credit unions often have lower rates than banks, especially if you're a member. Some credit unions will refinance cars from other lenders even if you don't currently bank with them; others require membership. Online lenders like LendingClub, Upgrade, and SoFi have streamlined the process process and sometimes offer competitive rates, though they may have stricter credit score requirements.
Banks like Wells Fargo, Chase, and Bank of America offer refinancing, but their rates are typically higher than credit unions for the same credit profile. However, if you already have a relationship with a bank, they may offer you a small rate discount.
When you request a rate quote, most lenders will do a soft credit pull that doesn't affect your score. You can request quotes from multiple lenders within a two-week window, and the credit bureaus treat these as a single inquiry rather than multiple inquiries, so your score won't drop significantly.
Fees and costs that reduce your savings
Refinancing isn't free. The new lender typically charges an process fee (usually $0 to $100), and your state charges a title transfer fee (typically $50 to $200, depending on the state). Some lenders also charge an origination fee, which is a percentage of the loan amount and can range from 1% to 5%.
Your original lender may charge a prepayment penalty if you pay off the loan early. This is less common than it used to be, but it still happens. Check your original loan documents or call your lender to ask. If the penalty is high, it may wipe out your savings from a lower rate.
To know whether refinancing makes sense, calculate your monthly savings and divide the total fees by that number. If the fees are $500 and you save $50 per month, you'll break even in 10 months. If you plan to keep the car for at least that long, refinancing is worth considering.
How the refinance process works and what to expect
The process starts with a rate quote. You provide basic information — your name, the car's year and mileage, and how much you still owe — and the lender gives you an estimated rate. This quote is usually good for 30 to 60 days.
Once you decide to move forward, you'll complete a full process. The lender will do a hard credit pull, verify your income, and order a title search to confirm you own the car and that there are no liens other than the current loan. This stage usually takes three to five business days.
If you're approved, the lender will send you loan documents to sign. You'll review the terms, the rate, and the monthly payment. Once you sign, the lender contacts your original lender to request a payoff quote — the exact amount needed to close your old loan on a specific date.
The new lender then wires the payoff amount to your original lender, and your old loan is closed. You'll receive a title release from the original lender, which you send to your new lender. The new lender records the title in their name and sends you new loan documents. The entire process typically takes one to two weeks from approval to funding.
When refinancing doesn't make sense
If you're very close to paying off your current loan, refinancing usually isn't worth it. Restarting the loan clock means you'll pay interest for longer, even if the rate is lower. If you have only 12 months of payments left, the math rarely works in your favor.
If your credit score is very low and you've recently missed payments or defaulted on other debts, lenders will either decline you or offer a rate that's higher than your current one. In this case, refinancing won't help. Focus on rebuilding your credit first.
If your car is very old or has very high mileage, many lenders won't refinance it at all. Some set hard limits at 100,000 or 120,000 miles; others will go higher but at rates that don't save you money. Check the lender's vehicle requirements before you explore.
If you're underwater on your loan — owing more than the car is worth — refinancing is harder but not impossible. Some lenders will refinance you, but they'll charge a higher rate to offset the risk. Calculate whether the savings are worth it before you proceed.
Questions to ask before you refinance
Ask your current lender whether there's a prepayment penalty and how much it is. This is the single most important question. If the penalty is high, it may eliminate your savings.
Ask the new lender whether the rate quote is locked in or whether it can change before closing. Some lenders lock the rate for 30 or 60 days; others reserve the right to adjust it based on market conditions or a final credit check.
Ask whether there are any fees beyond the process fee and origination fee. Some lenders charge document preparation fees, wire transfer fees, or title fees. Get the full list in writing.
Ask how long the process takes from process to funding. Most lenders say one to two weeks, but some are faster or slower. If you need the money quickly, this matters.
Frequently Asked Questions
Will refinancing hurt my credit score?
A hard credit pull will lower your score by a few points temporarily, usually recovering within a few months. However, refinancing can help your credit long-term by lowering your credit utilization ratio and showing you can manage multiple types of credit. The short-term dip is normal and expected.
Can I refinance a car I still owe money on?
Yes, that's the whole point of refinancing. The new lender pays off your old loan in full, and you owe them instead. You must own the car (or have the lender's lien released), but you don't need to have paid it off completely.
What if my car is worth less than I owe?
You're underwater, but refinancing is still possible. Some lenders will refinance you, though they may charge a higher rate or require a larger down payment. Others won't refinance underwater loans at all. Shop around, as policies vary widely.
How often can I refinance the same car?
There's no legal limit, but lenders may be hesitant to refinance a car that's already been refinanced multiple times. Each refinance restarts the loan term and adds fees, so doing it repeatedly can cost you more than you save. Most people refinance once, if at all.
Should I refinance if I only have a year of payments left?
Probably not. The fees and the cost of restarting the loan usually outweigh the savings from a lower rate over such a short period. Run the numbers, but in most cases, finishing your current loan is cheaper.
