Interest rates on car loans depend on your credit score, the loan term, the vehicle age, and the lender
The interest rate a lender offers you is not set by law or by the car manufacturer — it comes from the lender's own calculation of risk. If you have a credit score above 700, you might see rates between 4% and 7%. If your score is below 620, rates often land between 10% and 18%. The same lender will quote you different rates depending on whether you're financing a new car or a used one, and whether you're borrowing for 36 months or 72 months.
The rate you see advertised — say, "as low as 3.9%" — is what the lender offers to their best customers. You won't know your actual rate until you complete an process and the lender pulls your credit report. Even then, the rate can shift slightly depending on whether you make a down payment, whether you trade in a vehicle, and which specific lender you choose.
Key Takeaways
- Your credit score is the single biggest factor in the rate you receive; a score 100 points higher typically saves you 1% to 2% in interest.
- Loan term matters: a 36-month loan usually carries a lower rate than a 72-month loan from the same lender, even though the monthly payment is higher.
- Banks, credit unions, and dealership financing often quote different rates for the same borrower, so comparing at least two or three is worth the time.
- The interest rate and the annual percentage rate (APR) are not the same; APR includes fees and is the true cost of borrowing.
How your credit score shapes the rate you're offered
Lenders use your credit score as a shorthand for how likely you are to make payments on time. A higher score signals lower risk, and lower risk means a lower rate. The relationship is not linear — the jump in rate between a 620 score and a 650 score is often steeper than the jump between a 720 and a 750.
If your score is in the 300–500 range, you may find that mainstream lenders decline you altogether, and you'll need to look at credit unions or lenders that specialize in subprime auto loans. Those lenders charge higher rates to offset the higher default risk. If your score is 500–620, you'll see rates in the double digits. If it's 620–680, rates typically fall between 8% and 12%. Above 680, you enter the range where rates drop noticeably with each score increase.
Your credit score reflects your payment history, how much debt you're carrying, how long you've had credit accounts open, and recent hard inquiries. If you're shopping for a car loan and your score is lower than you'd like, you have options: wait a few months while you pay down other debts, dispute errors on your credit report, or ask a family member with better credit to co-sign the loan.
Why loan term length changes your rate
A loan term is how many months you have to repay the loan. Common terms are 36, 48, 60, and 72 months. Lenders charge a lower interest rate for shorter terms because they're exposed to less risk — they get their money back faster, and there's less time for your circumstances to change.
A 36-month loan might carry a 5.5% rate, while a 60-month loan from the same lender might be 6.2%, and a 72-month loan might be 6.8%. The longer the term, the more total interest you pay, even if the monthly payment looks smaller. A $25,000 loan at 5.5% over 36 months costs about $1,900 in interest; the same loan at 6.8% over 72 months costs about $5,700 in interest — nearly three times as much.
The trade-off is real: a shorter term means a higher monthly payment, which may not fit your budget. A longer term spreads the cost across more months, but you pay significantly more overall. Before you choose a term, calculate what the monthly payment would be and whether you can sustain it without cutting into savings or emergency funds.
New cars versus used cars, and what lenders charge
Lenders typically offer lower rates on new cars than on used cars of the same age. A new car has a warranty, a known maintenance history, and a predictable value. A used car is riskier — you don't know how the previous owner treated it, and its value can drop unpredictably. That extra risk translates to a rate that's often 1% to 3% higher than a new car rate.
The age of the used car also matters. A 3-year-old car will get a better rate than a 10-year-old car. Some lenders won't finance cars older than a certain year — often 10 or 15 years back — because the resale value becomes too uncertain. If you're buying an older used car, you may have fewer lenders to choose from, which can limit your ability to shop around for a better rate.
Where you borrow from makes a real difference
Three main types of lenders offer car loans: banks, credit unions, and dealership financing. Each has different rate structures and approval standards.
Banks are the largest lenders and have the most rigid credit requirements. They typically offer competitive rates to borrowers with good credit (scores above 680), but may decline borrowers with lower scores or charge them significantly higher rates. Banks often require a larger down payment than other lenders.
Credit unions are member-owned organizations that often charge lower rates than banks, especially for members with average or below-average credit. If you belong to a credit union, it's worth getting a rate quote there before you go to a bank or dealership. Some credit unions will work with you even if your score is lower, because they weigh factors like employment history and savings alongside your credit report.
Dealership financing is arranged through the car dealership itself, often through a captive finance company owned by the car manufacturer. Dealerships can sometimes offer promotional rates — "0% financing for 60 months" — but these are usually only available to borrowers with excellent credit. Dealership rates are often higher than bank or credit union rates for borrowers with average credit, because the dealership is taking on more risk and also earning a commission on the loan.
The difference between interest rate and APR
The interest rate is the percentage of the loan amount that you pay in interest each year. The annual percentage rate (APR) includes the interest rate plus any fees the lender charges — origination fees, documentation fees, or other costs. APR is always equal to or higher than the interest rate, and it's the number you should use when comparing loans.
If one lender quotes you a 6% interest rate with a $300 origination fee, and another quotes 6.2% with no fees, the APR will tell you which loan actually costs less. The lender is required to disclose the APR in writing before you sign, so you'll see it on the loan estimate or disclosure form. When you're comparing offers from different lenders, always compare APRs, not interest rates.
How to get the best rate for your situation
Start by checking your credit score before you explore anywhere. You can get a free report from AnnualCreditReport.com, which is the only official source for free credit reports. Knowing your score helps you understand what range of rates to expect and whether it's worth waiting a few months to improve your score before you borrow.
Get rate quotes from at least two or three lenders — a bank, a credit union if you're a member, and possibly a dealership. Each lender will do a hard inquiry on your credit, which temporarily lowers your score by a few points. Multiple inquiries for the same type of credit (auto loans) within 14 days usually count as a single inquiry, so do your shopping within a short window.
Compare the APR, not just the interest rate, and make sure you're comparing loans with the same term length. A lower monthly payment doesn't always mean a better deal if it comes from a longer term and higher total interest. Once you have offers in hand, you can negotiate with the dealership — if you have a pre-approved loan from a bank or credit union, you can tell the dealership you have outside financing and ask them to match or beat that rate.
Frequently Asked Questions
Can I get a lower rate if I make a bigger down payment?
Yes. A larger down payment reduces the amount you need to borrow, which lowers the lender's risk. Many lenders will offer a rate reduction of 0.25% to 0.5% if you put down 20% or more instead of 10%. The reduction varies by lender, so ask about it when you get your quote.
What's a good interest rate for a car loan right now?
Rates change constantly based on the broader economy, so there's no single "good" rate. For a new car with good credit, rates typically range from 4% to 7%. For a used car or lower credit, expect 7% to 12% or higher. Your own rate depends on your credit score, the loan term, and the lender you choose.
Can I refinance my car loan if rates drop?
Yes. If interest rates fall significantly after you take out your loan, you can refinance — take out a new loan to pay off the old one. You'll pay a small fee to the new lender, but if the new rate is low enough, you'll save money over the life of the loan. Refinancing makes most sense if you have good credit and at least a year of on-time payments behind you.
Does shopping for rates hurt my credit score?
Multiple inquiries for auto loans within 14 days typically count as one inquiry, so shopping around causes minimal damage. Your score may drop 5 to 10 points temporarily, but it recovers within a few months if you make your payments on time. The benefit of finding a lower rate outweighs the temporary score dip.
Why did the dealership offer me a different rate than the bank?
Dealerships and banks use different risk models and have different profit margins. A dealership may offer a higher rate because they're taking on more risk, or because they're earning a commission on the loan. That's why it's important to compare offers — the dealership's rate isn't necessarily the only option available to you.
