Auto loan refinancing rates are the interest percentages lenders charge when you replace your current car loan with a new one
When you refinance an auto loan, you're asking a new lender to pay off your existing loan in full, then you owe money to that new lender instead. The rate they charge you is called the refinancing rate. It's a separate number from your original loan rate — it can be lower, higher, or the same, depending on your credit score, the lender, how much time is left on your loan, and what the broader interest rate environment looks like at that moment.
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. But refinancing only makes financial sense if the new rate is meaningfully lower than what you're currently paying, because the process itself has costs and takes time.
Key Takeaways
- Refinancing rates depend on your credit score, the lender you choose, how much of your loan remains, and current market conditions — not on your original rate.
- You'll typically save money only if your new rate is at least 1 to 2 percentage points lower than your current rate, because refinancing has costs and resets your loan timeline.
- Banks, credit unions, and online lenders all offer refinancing, and rates vary between them — getting quotes from at least three lenders helps you compare.
- Your credit score is the single biggest factor lenders look at, so checking your score before you shop tells you roughly what rate range to expect.
How lenders decide what refinancing rate to offer you
A lender's decision about your rate starts with your credit score. If your score has improved since you took out your original loan, you may may have access to for a lower rate. If it's dropped, you'll likely see a higher one. Lenders also look at how much you still owe compared to what the car is worth — if you're underwater on the loan (you owe more than the car is worth), some lenders won't refinance you at all, or will charge a higher rate to offset their risk.
The age and mileage of your car matter too. A car with 150,000 miles is riskier collateral than one with 50,000 miles, so lenders may offer worse rates or decline to refinance. How much of your loan is left also factors in — refinancing a loan with only six months remaining usually doesn't make financial sense, because you won't benefit from the lower rate long enough to recoup the refinancing costs.
Finally, lenders price their rates based on what the Federal Reserve has done with its benchmark interest rate and what's happening in the broader economy. When the Fed raises rates, auto refinancing rates typically rise too. When the Fed cuts rates, refinancing rates usually fall, which is often when people shop around for better deals.
Where refinancing rates come from and why they vary
Banks, credit unions, and online lenders all set their own rates based on their cost of borrowing money and how much profit they want to make. A credit union might offer 5.2% while a bank offers 5.8% for the same borrower — the difference reflects their different business models and risk appetites. Credit unions are often cheaper because they're member-owned and don't have to generate profits for shareholders, but they may have membership requirements or stricter lending rules.
Online lenders often advertise competitive rates because they have lower overhead costs than brick-and-mortar banks. However, the rate you see advertised is usually the best rate available to borrowers with excellent credit — if your credit is good but not excellent, you'll likely be offered something higher.
The type of vehicle you're refinancing also affects the rate. A loan on a 2022 Honda Civic will typically carry a lower rate than a loan on a 2015 Kia Sportage, because newer cars hold their value better and are less likely to need expensive repairs.
The real cost of refinancing: fees and timing
Refinancing isn't free. Most lenders charge an origination fee (usually 0% to 2% of the loan amount), and you may have to pay for a title transfer, a credit report pull, or a vehicle inspection. Some lenders waive origination fees to attract customers, but read the fine print — they may be building the cost into the interest rate instead. A few lenders charge no fees at all, which is why comparing multiple offers matters.
There's also a timing cost. When you refinance, you're resetting your loan term. If you had three years left on your original loan and you refinance into a new five-year loan, you're extending your debt even if your monthly payment drops. You'll pay interest for two extra years, which can wipe out savings from a lower rate. The math only works in your favor if your new rate is low enough to offset both the refinancing fees and the extended timeline.
A general rule: refinancing makes sense if your new rate is at least 1 to 2 percentage points lower than your current rate and you have at least two years of payments remaining. If the gap is smaller or your loan is almost paid off, the costs outweigh the benefits.
How to find out what refinancing rate you might get
Start by checking your credit score through a free service like AnnualCreditReport.com or your bank's website. Your score is the primary number lenders use to price your rate, so knowing it gives you a realistic sense of what to expect. A score above 750 typically qualifies for the best rates; a score between 650 and 749 qualifies for mid-range rates; below 650 usually means higher rates or outright rejection from some lenders.
Next, gather information about your current loan: the balance you still owe, your current interest rate, and how many months are left. You'll need this when you get quotes. Then contact at least three lenders — your current bank or credit union, one or two other credit unions if you're a member, and one or two online lenders. Most will give you a rate quote without a hard credit pull, which means checking with multiple lenders won't damage your credit score.
When you get quotes, compare the interest rate, any fees, the new loan term, and the new monthly payment. Use an auto loan calculator to see how much total interest you'd pay over the life of the new loan, then subtract the refinancing fees. If that number is lower than what you'd pay on your current loan, refinancing saves you money.
When refinancing rates are worth pursuing
The best time to refinance is usually when interest rates have dropped since you took out your original loan, or when your credit score has improved significantly. If you took out a loan at 8% and rates have fallen to 5%, refinancing is almost certainly worth exploring. If your score was 620 when you borrowed and is now 720, you'll likely see a meaningful rate drop.
Refinancing also makes sense if you've paid down a substantial portion of your loan and want to shorten the term. For example, if you have $8,000 left on a loan with four years remaining, you might refinance into a two-year loan at a similar or slightly higher rate — your monthly payment goes up, but you're debt-free faster and pay less total interest.
Refinancing rarely makes sense if you're underwater on your loan, if you have less than two years of payments left, or if your credit score has dropped since you borrowed. In those situations, the costs and risks outweigh any potential savings.
Frequently Asked Questions
Will shopping for refinancing rates hurt my credit score?
A single hard credit pull can lower your score by a few points, but multiple pulls from different lenders within a short window (usually 14 to 45 days, depending on the scoring model) count as one inquiry. So getting quotes from three or four lenders in the same week has minimal impact. Your score will recover within a few months.
Can I refinance if I'm behind on my current loan payments?
Most lenders won't refinance you if you're currently delinquent. You'll need to bring your account current first, then wait a few months for your payment history to stabilize before explore. Some credit unions are more flexible, so it's worth asking, but expect to be turned down by most mainstream lenders.
What's the difference between a refinancing rate and my original loan rate?
Your original rate was set based on your credit score, the car, and market conditions when you first borrowed. Your refinancing rate is a completely new rate set by a different lender (or the same lender) based on your current credit score, the car's current age and mileage, and today's market conditions. They're independent numbers.
Do I have to refinance with my current lender?
No. You can refinance with any lender that will approve you. Many people refinance with a different bank or credit union to get a better rate. Your current lender has no say in the decision — once the new lender pays off your loan, you owe the new lender instead.
How long does refinancing take?
From process to funding usually takes five to ten business days, though some online lenders can move faster. During that time, you'll submit documents, the lender will order a title search, and they'll arrange to pay off your old loan. You'll continue making payments to your original lender until the refinance closes.
