Used car loan rates are typically higher than new car rates, but the difference depends on the car's age, your credit score, and the lender you choose

When you finance a used car, lenders charge you a higher interest rate than they would for a new car — usually between 0.5% and 2% more, though this varies widely. The reason is straightforward: a used car loses value faster and is worth less as collateral if you stop paying. A lender taking on that extra risk charges more to cover it. Your actual rate depends on three main things: how old the car is, your credit history, and whether you're borrowing from a bank, credit union, or the dealership itself.

The age of the car matters more than you might think. A three-year-old vehicle will get you a better rate than a ten-year-old one, because the newer car is less likely to need expensive repairs that could leave you unable to pay. Lenders often have cutoff ages — some won't finance cars older than 10 years, or they'll charge significantly more for anything past that point. Your credit score is the other major lever: if you have a score above 700, you'll see rates that are competitive with new car financing. Below 620, you may find rates jump by several percentage points, or some lenders may decline you altogether.

Key Takeaways

  • Used car rates run 0.5% to 2% higher than new car rates, depending on the car's age and your credit score.
  • Cars older than 10 years often face higher rates or may not be financed by traditional lenders at all.
  • Credit unions typically offer lower rates than banks or dealerships, even if your credit is not perfect.
  • The rate you see advertised is not the rate you will get — your actual rate depends on your credit report and the specific vehicle.
  • Comparing offers from multiple lenders before you buy can save you hundreds of dollars over the life of the loan.

How lender type affects your rate

Where you borrow from makes a real difference. Banks, credit unions, and dealerships all price used car loans differently. Credit unions — which you join through an employer, school, or community membership — typically offer the lowest rates because they're nonprofit and return profits to members. Banks come next, and dealerships usually charge the most, partly because they're offering you convenience (you can finance right there) and partly because they're making money on the loan itself.

If you have weak credit, a credit union is often your best bet. Many credit unions have programs specifically for members with scores below 650, and they'll look at your full financial picture rather than just a number. Banks tend to have stricter cutoffs. Dealerships will finance almost anyone, but the rate can be steep — sometimes 8% to 12% or higher for used cars if your credit is below 620. The catch with dealership financing is that they may also mark up the rate after you sign, a practice called "dealer reserve," though this is becoming less common.

What your credit score actually means for your rate

Your credit score is the single biggest factor lenders look at, and the relationship is not linear — meaning a score of 650 doesn't just get you a slightly worse rate than 700. The jumps are often steep. A score of 750 and above might get you 4% to 6% on a used car. A score between 650 and 749 might be 6% to 9%. Below 650, you could see 10% to 15% or higher. These ranges shift based on the lender, the car's age, and current market conditions, so they're not fixed.

Your credit score reflects your payment history, how much debt you're carrying, and how long you've had credit accounts open. If you've missed payments or have high credit card balances, your score will be lower, and lenders will charge more because they see you as riskier. Before you shop for a car, it's worth checking your credit report for errors — you can get a free report once a year from AnnualCreditReport.com. Fixing errors can sometimes raise your score by 10 to 50 points, which can lower your rate by half a percentage point or more.

The car's age and mileage in rate calculations

Lenders use the car's age and mileage to estimate how much longer it will run without major repairs. A five-year-old car with 60,000 miles is a much safer bet than a ten-year-old car with 150,000 miles. Most lenders have a mileage threshold — often 100,000 to 120,000 miles — beyond which they either won't finance or will charge noticeably more. Some lenders also won't touch cars with salvage titles (meaning they were declared a total loss by an insurance company at some point), even if they've been repaired.

The make and model matter too, though lenders don't always advertise this. A Toyota or Honda with high mileage is easier to finance than a less reliable brand, because the lender knows it's more likely to keep running. If you're shopping for a used car and your credit is not strong, choosing a reliable brand with lower mileage can mean the difference between getting financed and being turned down, or between a 10% rate and a 7% rate.

How to compare offers before you buy

The best time to shop for a loan is before you walk into a dealership. Get pre-approved from your bank or credit union — this means they've looked at your credit and told you the rate and amount they'll lend you. Pre-approval is free and doesn't hurt your credit score. Armed with that offer, you can negotiate with the dealership from a position of strength. You can tell them, "I have financing at 6.5% for $15,000 — beat that and I'll use yours."

When you compare offers, look at the interest rate, but also the loan term (how many months you'll pay). A lower rate over 72 months might cost you more in total interest than a slightly higher rate over 48 months. Use an online calculator to see the total amount you'll pay under each scenario. Also ask whether the rate is fixed (stays the same for the life of the loan) or variable (can change) — for used cars, fixed rates are standard, but it's worth confirming.

Why dealer rates can change after you sign

Some dealerships use a practice called "spot delivery," where you drive the car home before the financing is finalized. The dealership then contacts you days or weeks later saying the bank didn't approve the rate they quoted, and you need to come back and sign new paperwork at a higher rate. This is legal in most states, though some states have banned it or limited it. If this happens to you, you have the right to refuse and return the car — you're not locked in until you've signed final paperwork.

To avoid this, ask the dealership upfront whether the rate is final before you sign. Get everything in writing. If they say the financing is contingent on bank approval, understand that the rate could change. If you've already been pre-approved by your own lender, you don't have to accept a worse rate from the dealership — you can straightforward use your pre-approval instead.

Down payment and how it affects your rate

Putting more money down doesn't directly change your interest rate, but it does change how much you're borrowing, which affects your total interest cost. If you put down 20% instead of 10%, you're borrowing less, so you'll pay less interest overall even at the same rate. A larger down payment also makes you look less risky to lenders, which can sometimes help you get approved if you're on the edge, or get a slightly better rate.

For used cars, lenders often want a down payment of at least 10% to 20% of the car's price. If you can't put down that much, some lenders will still work with you, but your rate will be higher because you're borrowing a larger percentage of the car's value. If the car is very old or has high mileage, a larger down payment becomes even more important — it signals to the lender that you're serious and invested in the purchase.

Frequently Asked Questions

Will my rate change if I refinance the loan later?

Yes. If your credit score improves or interest rates drop, you can refinance — take out a new loan to pay off the old one. Your new rate will depend on your credit score at that time and current market rates. Refinancing makes sense if you can lower your rate by at least 1%, because the savings will outweigh the costs of the new loan. You can refinance through a bank or credit union, and you don't have to use the same lender you borrowed from originally.

Can I get a better rate if I have a co-signer?

Yes. A co-signer with good credit can help you get approved and lower your rate. The co-signer is legally responsible for the loan if you don't pay, so they're taking on real risk — make sure they understand that before they agree. If you have a co-signer, the lender will look at both of your credit scores and may use the better one to set your rate.

What's the difference between APR and interest rate?

The interest rate is what you pay to borrow the money. The APR (annual percentage rate) includes the interest rate plus other costs like origination fees. When comparing loans, always compare APRs, not just interest rates, because the APR tells you the true cost. Lenders are required to show you the APR before you sign.

Do I have to use the dealership's financing?

No. You can bring your own financing from a bank or credit union. The dealership may try to convince you to use theirs, but you have the right to decline. Using outside financing also protects you from spot delivery — if you've already been approved and funded by your own lender, the dealership can't call you back later asking for a higher rate.

How long does it take to get approved for a used car loan?

Pre-approval from a bank or credit union usually takes one to three business days. Final approval after you've chosen a specific car can take a few days to a week. Dealership financing can sometimes be faster — same day or next day — but speed often comes at the cost of a higher rate. Plan to spend at least a few days on the financing process.
