Automobile refinance rates are the interest percentages lenders charge when you replace your existing auto loan with a new one
A refinance rate is straightforward the interest rate on a new loan that pays off your old one. It's not a special category of rate — it's whatever rate a lender offers you based on their assessment of your credit, the car's value, and how much time is left on the original loan. The rate you get depends on your credit score, the lender you choose, current market conditions, and how much equity you have in the vehicle.
The goal of refinancing is usually to lower your monthly payment, reduce the total interest you'll pay, or both. Whether that happens depends on whether your new rate is lower than your current rate, how many months remain on your loan, and how long you extend the new loan. A lower rate doesn't automatically mean a lower payment if you stretch the loan over more months.
Key Takeaways
- Your refinance rate depends primarily on your credit score, the lender's current rates, and how much of the car's value you still owe.
- Rates vary significantly between banks, credit unions, and online lenders, so comparing offers from at least three sources is standard practice.
- A lower refinance rate only saves you money if the new rate is lower than your current rate and you don't extend the loan term significantly.
- Lenders typically pull your credit report during the rate-shopping process, but multiple inquiries within 14 days usually count as one inquiry for credit scoring purposes.
How your credit score affects the rate you're offered
Lenders use your credit score as the primary factor in setting your rate. A higher score — generally 740 and above — typically qualifies you for the lowest rates a lender offers. Scores in the 670 to 739 range usually get standard rates. Scores below 670 may face higher rates or outright rejection, depending on the lender.
Your credit report also matters. Lenders look at payment history, how much debt you're carrying, and recent inquiries. If you've missed payments on your current auto loan, refinancing becomes harder and more expensive. If you've paid on time and your credit has improved since you took out the original loan, refinancing can save you real money.
You can check your own credit score for free through AnnualCreditReport.com or through your bank's website. Knowing your score before you shop for rates helps you understand what range to expect and whether it's worth refinancing at all.
Why rates differ between banks, credit unions, and online lenders
Banks, credit unions, and online lenders set rates differently because they have different cost structures and risk appetites. Credit unions are member-owned nonprofits and often offer lower rates to members, especially if you've banked there for years. Banks have higher overhead and may price rates to cover it. Online lenders compete heavily on rate but may have stricter credit requirements or faster approval timelines.
The same lender may also offer different rates depending on whether you're a new customer, how much you're borrowing, and the age of the vehicle. A 2022 car refinances more easily than a 2015 car because it holds its value better. A $5,000 refinance may carry a different rate than a $25,000 one.
Shopping around is the only way to find the best rate for your situation. Most lenders let you get a rate quote without a hard credit pull, or with a soft inquiry that doesn't affect your score. Once you're ready to move forward, the lender will do a hard pull. Multiple hard inquiries within 14 days typically count as a single inquiry for credit scoring, so you can shop without major damage to your score.
What market conditions and timing mean for your rate
Refinance rates move with broader economic conditions, particularly Federal Reserve policy and the bond market. When the Fed raises its benchmark rate, auto refinance rates typically rise within weeks. When the Fed cuts rates, lenders usually lower their rates, though not always when ready or by the same amount.
You can't predict rate movements, but you can monitor them. The Federal Reserve's website shows historical rate decisions. Bankrate, LendingTree, and Edmunds publish average auto refinance rates weekly, broken down by credit tier. If rates are falling and you're on the fence, checking these sites weekly can help you decide whether to wait or move forward now.
Timing also depends on your personal situation. If you're planning to sell the car in two years, refinancing into a longer loan doesn't make sense. If you're keeping it for five more years and rates have dropped since you bought it, refinancing could save thousands in interest.
How the car's age and value affect what rate you can get
Lenders care about the car's current market value because it's their collateral if you default. A newer car with higher resale value is less risky, so lenders offer better rates. A 2024 model might may have access to for a rate 0.5 to 1 percent lower than a 2018 model, all else equal.
The amount you owe relative to the car's value — called your loan-to-value ratio — also matters. If you owe $15,000 on a car worth $20,000, you have equity and refinancing is straightforward. If you owe $18,000 on that same car, you're underwater, and many lenders won't refinance you at all. Some will, but at a higher rate to offset the risk.
You can check your car's estimated value on Kelley Blue Book or NADA Guides. Knowing this number before you shop tells you whether you have equity to work with and what rate range to expect.
Comparing rate offers and understanding what they include
When you get a rate quote, the lender should provide a Loan Estimate that shows the interest rate, the monthly payment, the total interest you'll pay over the life of the loan, and any fees. Compare the total interest paid, not just the monthly payment, because a lower payment sometimes means you're paying more interest overall.
Watch for origination fees, which some lenders charge to process the loan. These typically range from $0 to $500 and are either paid upfront or rolled into the loan. A lender with a slightly higher rate but no fee might cost less than one with a lower rate and a $300 fee. The Loan Estimate shows this clearly.
Also check whether the rate is fixed or variable. Auto refinance rates are almost always fixed, meaning your rate and payment don't change for the life of the loan. If a lender offers a variable rate, understand exactly how and when it can change before you accept it.
When refinancing makes financial sense and when it doesn't
Refinancing makes sense if your new rate is at least 0.5 to 1 percent lower than your current rate and you plan to keep the car long enough to recoup any fees. If you're refinancing a $20,000 loan and the new lender charges a $300 fee, you need enough interest savings to cover that fee plus justify the effort.
Refinancing doesn't make sense if you're underwater on the loan, if your credit has worsened since you took out the original loan, or if you're planning to sell or trade the car soon. It also doesn't make sense if you're near the end of the original loan term — if you have 12 months left and you'd refinance into a 60-month loan, you're extending the debt significantly.
Use a refinance calculator to compare your current loan against potential new loans. Input your current balance, rate, and remaining months, then compare it against the new loan's rate and term. The calculator will show you the total interest difference and whether it's worth doing.
Frequently Asked Questions
Will shopping for refinance rates hurt my credit score?
Multiple rate inquiries within 14 days typically count as one hard inquiry for credit scoring purposes, so shopping around causes minimal damage. Your score may drop 5 to 10 points temporarily, but it usually recovers within a few months. Avoid opening new credit accounts or making large purchases during the refinancing process.
Can I refinance a car I still owe money on?
Yes, that's the standard situation. You refinance by paying off the old loan with the new loan. If you have equity in the car, refinancing is straightforward. If you're underwater, some lenders will still refinance you, but at a higher rate or with stricter terms.
What's the difference between a rate quote and a final rate?
A rate quote is an estimate based on the information you provide and a soft credit pull. A final rate comes after a hard credit pull and verification of your income and employment. The final rate is usually within 0.25 percent of the quote, but it can differ if your credit report shows something unexpected or if you've missed a payment recently.
How long does it take to get a new rate after I explore?
Most lenders can provide a rate quote within hours or a day. Approval and funding typically take 3 to 7 business days, depending on the lender and how quickly you provide documents. Some online lenders fund within 24 hours; traditional banks may take longer.
Should I refinance if rates are only slightly lower than my current rate?
Only if you're keeping the car long enough to recoup any fees and the monthly savings are meaningful to your budget. If your current rate is 5.5 percent and you can refinance at 5.0 percent, the savings depend on how much you owe and how many months remain. Use a calculator to see the total interest difference before deciding.
