What a refinance rate is and why it matters
An auto loan refinance rate is the interest rate a lender offers when you replace your current car loan with a new one. You keep the same car and the same lender (or switch to a different one), but you get a fresh loan agreement with new terms—usually a lower rate, a shorter payoff period, or both.
The reason people refinance is straightforward: if your current rate is higher than what lenders are offering now, refinancing can lower your monthly payment or let you pay off the car faster. The difference between a 6% rate and a 4% rate on a $25,000 loan adds up to real money over the life of the loan.
Refinance rates are not the same as the rate you got when you first bought the car. They depend on current market conditions, your credit score at the time you refinance (not when you originally borrowed), and the lender you choose. A rate that works for one person might not be available to another.
Key Takeaways
- Refinance rates are set by individual lenders and change based on your current credit score, the age of your car, how much you still owe, and what the broader lending market is doing.
- You can refinance through your current lender, a different bank, a credit union, or an online lender, and each may offer different rates.
- Refinancing makes the most sense when your credit score has improved since you took out the original loan, or when market rates have dropped.
- The process takes a few days to a couple of weeks, and you will need your current loan details and proof of car insurance before you start.
- Refinancing resets your loan term, so you might pay less per month but take longer to own the car outright, depending on the terms you choose.
How lenders decide what rate to offer you
When you ask for a refinance rate, the lender pulls your credit report and score. This is the single biggest factor. If your score has gone up since you took out the original loan—because you have paid bills on time, paid down other debt, or fixed errors on your report—you will likely see a lower rate.
Lenders also look at how much you still owe compared to what the car is worth. If you owe $15,000 on a car worth $20,000, that is a safer loan for the lender than owing $18,000 on the same car. The safer the loan looks, the lower the rate they will offer.
The age and mileage of your car matter too. A 2-year-old car with 30,000 miles is easier to refinance than a 10-year-old car with 150,000 miles. Some lenders will not refinance cars older than a certain age or with too many miles, no matter what your credit score is.
Finally, the broader lending market affects what rates are available. When the Federal Reserve raises interest rates, auto refinance rates tend to rise across the board. When rates fall, refinance offers improve. You cannot control this, but it is worth checking what rates look like before you decide to refinance.
Where to find and compare refinance rates
You can get a refinance rate from your current lender, a different bank, a credit union, or an online lender. Each source may offer different rates, so it is worth checking more than one.
Your current lender already has your loan history and payment record, which can work in your favor. They may offer you a rate without a hard credit pull, or they may move quickly because they already know you. Call or log into your account to ask what they can offer.
Banks and credit unions often have competitive rates, especially if you are a member or customer. Credit unions in particular sometimes offer lower rates to members, and they may be more flexible about car age or mileage. You can search for credit unions in your area through the CO-OP Network or Alliant Credit Union's shared branching system.
Online lenders and auto refinance marketplaces let you compare offers from multiple lenders at once. When you submit information, each lender will pull your credit (a hard inquiry) and send you a rate quote. Doing this within a short window—typically 14 to 45 days, depending on the credit bureau—counts as a single inquiry, so it does not hurt your score as much as explore to many lenders over time.
What happens to your loan when you refinance
When you refinance, your old loan is paid off in full using money from your new loan. You then owe the new lender instead of the old one. Your car title does not change hands—you still own it—but the lender's lien (their legal claim to the car if you stop paying) transfers to the new lender.
You get to choose the new loan term. You might refinance into a shorter term (paying it off faster) or a longer term (lowering your monthly payment). A lower rate does not automatically mean a lower payment if you extend the term. For example, refinancing from 72 months at 6% to 84 months at 4% might lower your payment even though you are paying for the car longer.
The new lender will require proof of insurance before they fund the loan. They will also verify that the car still exists and is in reasonable condition. Some lenders do a quick phone or video inspection; others just ask for photos. This is standard and takes a day or two.
When refinancing makes sense and when it does not
Refinancing makes sense when your credit score has improved enough to get a meaningfully lower rate, or when market rates have dropped since you borrowed. A drop of even 1% can save hundreds of dollars over the life of the loan. Use an auto loan calculator to see the actual savings before you start the process.
Refinancing does not make sense if you are close to paying off the car. If you have only 12 months left on your loan, the interest you save will be small, and you will pay fees (usually $0 to $200, depending on the lender) that eat into those savings. It also does not make sense if your credit score has not improved and lenders are offering rates similar to or higher than what you have now.
Be cautious about refinancing into a much longer term just to lower your payment. You will pay more interest overall, and you risk owing more than the car is worth if it depreciates quickly. This situation—owing more than the car is worth—is called being "upside down" on the loan, and it can trap you if the car breaks down or you want to sell it.
The refinancing timeline and what you need to prepare
The process usually takes 5 to 14 business days from process to funding. The lender will ask for your current loan information (account number, lender name, payoff amount), proof of insurance, and the vehicle identification number (VIN). Have these ready before you explore.
Once you submit your process, the lender will pull your credit and verify the car's details. If everything checks out, they will send you a loan agreement to sign. You sign it (often electronically), and the lender pays off your old loan directly. Your old lender sends you a release of lien, which means they no longer have a claim to the car.
During this time, keep making payments to your old lender on schedule unless the new lender tells you to stop. Do not assume the old loan is paid off just because you have applied for refinancing. If you miss a payment while the refinance is processing, it will damage your credit score.
Costs and fees to watch for
Most auto refinance lenders charge no process fee, no origination fee, and no prepayment penalty. However, some lenders do charge one or more of these. Before you commit, ask the lender for a complete list of fees.
Your state or county may charge a title transfer fee or a lien release fee when the lender changes. This is usually $25 to $100 and goes to the government, not the lender. The lender will tell you if this applies in your state.
Some lenders offer a discount if you set up automatic payments from a bank account. This discount is typically 0.25% to 0.5% off your rate, which can add up over time. Ask about this when you are comparing offers.
Frequently Asked Questions
Will refinancing hurt my credit score?
A hard credit inquiry will lower your score by a few points temporarily, but the impact fades within a few months. If you explore to multiple lenders within 14 to 45 days, the inquiries count as one, so the damage is minimal. Making on-time payments on your new loan will rebuild your score over time.
Can I refinance if I am behind on payments?
Most lenders will not refinance if you are currently behind or have missed payments in the last 30 to 90 days. Catch up on your current loan first, then wait a few months before refinancing. A recent late payment signals risk to new lenders.
What if I still owe more than the car is worth?
Being upside down on your loan makes refinancing harder but not impossible. Some lenders will refinance even if you owe more than the car is worth, but they may charge a higher rate or require a larger down payment. Ask lenders directly whether they refinance upside-down loans.
Can I refinance a car I am still paying off?
Yes, that is the whole point of refinancing. You can refinance as soon as your original loan is a few months old. There is no rule that says you have to wait a certain amount of time, though some lenders prefer to see at least 6 to 12 months of payment history.
Do I need to refinance through a bank, or can I use an online lender?
Online lenders, banks, and credit unions all offer auto refinancing. Online lenders often move faster and may have more flexible requirements, but banks and credit unions may offer better rates if you are a member. Compare offers from all three types before deciding.
