Second-hand car loans usually carry higher interest rates than new car loans, often by 1 to 3 percentage points, because the vehicle depreciates faster and lenders see more risk if you default.

A lender's rate depends on the car's age, mileage, condition, your credit score, the loan term you choose, and which lender you use. A five-year-old sedan with 60,000 miles will get you a better rate than a ten-year-old one with 120,000 miles. If your credit score is 750 or above, you'll see rates in the 4 to 7 percent range at most banks and credit unions; if it's below 650, expect 10 to 18 percent or higher, and some lenders won't touch you at all.

The age cutoff matters. Most banks won't finance cars older than 10 years, and some stop at 8 years. Credit unions are often more flexible—some will go to 12 or 15 years—but they charge more for the risk. Certified pre-owned (CPO) vehicles, which come with a manufacturer's warranty and have passed inspection, sometimes may have access to for rates closer to new car rates, but not always; it depends on the lender's rules and how old the car is.

Key Takeaways

  • Second-hand car loan rates are typically 1 to 3 percentage points higher than new car rates because the vehicle loses value faster and poses more risk to the lender.
  • Your credit score, the car's age and mileage, and the loan term all affect your rate; a car older than 10 years will be harder to finance and more expensive when you do.
  • Credit unions often finance older vehicles than banks do, but charge higher rates in return for that flexibility.
  • Getting pre-approved before you shop lets you see what rate you actually may have access to for and gives you negotiating power at the dealership.

How Lenders Price Second-Hand Car Loans Differently

A new car loses about 20 percent of its value in the first year and continues depreciating. By year five, it's worth roughly 50 to 60 percent of what you paid. A used car depreciates more slowly in absolute dollars but faster as a percentage of what it's worth. If you owe $15,000 on a $20,000 used car and the transmission fails, the car might be worth $12,000 to repair, leaving you underwater on the loan. A lender financing a new car faces less of that risk because the car's value drops more slowly.

Lenders also worry about the car's history. A used car might have had multiple owners, unknown accident damage, or deferred maintenance. A new car comes with a manufacturer's warranty that covers major failures for the first three years or 36,000 miles. That warranty is worth money to a lender because it reduces the chance you'll stop paying if something breaks. A used car's warranty, if it exists at all, is shorter and narrower.

The loan term you choose affects your rate too. A 36-month loan on a used car will have a lower rate than a 72-month loan on the same car, because the lender gets their money back faster and the car is worth more relative to what you owe. Stretching the loan to 84 months (seven years) is common for used cars but will cost you more in interest and lock you into a longer payment period.

What Your Credit Score Actually Determines

Your credit score is the single biggest factor in your rate. Lenders use it to predict whether you'll pay on time. A score of 750 or above typically gets you the best rates available—often 4 to 7 percent for a used car, depending on the lender and the car. A score between 700 and 749 might see rates of 6 to 10 percent. Below 700, rates climb quickly: 650 to 699 might be 10 to 14 percent, and below 650 can be 14 to 18 percent or higher.

Some lenders won't finance anyone below a certain score—often 620 or 650—so if your score is very low, you may have fewer options. Credit unions are sometimes more willing to work with lower scores than banks are, but they'll charge you for it. Subprime lenders (lenders who specialize in borrowers with poor credit) will finance almost anyone, but rates can exceed 20 percent, and the terms are often predatory—high down payments, short loan terms, or clauses that let them repossess the car quickly if you miss a payment.

Checking your own credit report before you shop is worth doing. You can get a free report once a year from each of the three major bureaus—Equifax, Experian, and TransUnion—at annualcreditreport.com. If there are errors, dispute them; correcting a mistake can raise your score by 20 to 100 points, which translates directly to a lower rate.

Banks, Credit Unions, and Online Lenders: Where Rates Differ Most

Banks offer competitive rates if your credit is good, but they're stricter about the car's age and condition. Most banks won't finance a car older than 10 years, and some have a cutoff at 8 years. They also require a pre-purchase inspection from a mechanic they approve, which costs $100 to $200 and adds time to the process. Banks move slowly—approval can take a week or more—but their rates are usually the lowest if you may have access to.

Credit unions typically offer rates 0.5 to 1 percentage point lower than banks for the same borrower and car, but only if you're a member. Membership usually requires living or working in a certain area, belonging to a profession, or being related to a current member. Credit unions are more flexible about car age—some will finance vehicles up to 15 years old—and they're often more willing to work with lower credit scores. The tradeoff is that they may require a larger down payment or a co-signer if your score is below 650.

Online lenders and marketplace platforms (like LendingClub or Upstart) can approve you in hours and fund in days, which is appealing if you're in a hurry. Their rates vary widely—some are competitive with banks, others are in the subprime range—and they often have looser rules about car age. The catch is that you may not know your actual rate until after you've submitted personal and financial information, and some online lenders sell your loan to a third party after closing, which can change your terms or payment method.

Pre-Approval: What It Tells You and Why It Matters

Getting pre-approved means a lender has reviewed your credit and finances and told you what rate and loan amount you may have access to for, before you've picked a car. Pre-approval is not a may provide—the lender will still inspect the car and verify your employment and income before funding—but it gives you a real number to work with, not a marketing estimate.

Pre-approval also gives you negotiating power. When you walk into a dealership with a pre-approval letter, you know exactly what you can afford and what rate you're paying. The dealership can't pressure you into a higher rate or longer term because you have an outside offer. If the dealership's finance manager offers you a better rate, you can take it; if not, you walk away knowing you have funding lined up.

Most banks and credit unions pre-approve you for free and hold the pre-approval for 30 to 60 days. Online lenders vary—some pre-approve when ready, others require a hard credit pull (which temporarily lowers your score by a few points). If you're shopping around, do all your pre-approvals within a two-week window; multiple credit inquiries in a short time count as one inquiry for scoring purposes, so they won't damage your score as much as spread-out inquiries would.

How Car Age and Mileage Push Rates Up

A car's age is a hard boundary for most lenders. Banks typically won't finance anything older than 10 years; credit unions might go to 12 or 15 years. If a car is at or near that boundary, you'll pay a premium—often 1 to 2 percentage points higher than a newer car—because the lender is taking on more risk that the car will fail or become worthless before you pay off the loan.

Mileage matters less than age, but it still factors in. A five-year-old car with 40,000 miles is in better shape than a five-year-old car with 100,000 miles. Lenders use mileage to estimate how much life is left in the engine, transmission, and other major components. High mileage (over 100,000 miles) can add 0.5 to 1 percentage point to your rate, or disqualify you entirely if the lender has a hard mileage cap.

Certified pre-owned vehicles sometimes get better rates because they've passed a manufacturer's inspection and come with an extended warranty. A CPO car might may have access to for a rate 0.5 to 1 percentage point lower than a non-certified used car of the same age and mileage. However, CPO cars cost more upfront, so the savings in interest may not offset the higher purchase price.

Loan Term and Total Interest: The Long-Term Cost

A 36-month loan on a used car will have a lower interest rate than a 60-month or 84-month loan on the same car, but your monthly payment will be higher. A 60-month loan spreads the cost over five years, lowering your monthly payment but raising the total interest you pay. An 84-month loan (seven years) is increasingly common for used cars, especially if the car is older or has higher mileage, because it keeps the monthly payment manageable—but you'll pay significantly more in interest over the life of the loan.

The math is straightforward: a $15,000 loan at 8 percent for 36 months costs about $2,000 in interest; the same loan at 8 percent for 72 months costs about $4,000 in interest. You're paying twice as much for the money, even though the interest rate is the same. If the lender charges you 10 percent instead of 8 percent for the longer term, the interest bill climbs even higher.

Choosing a loan term is a trade-off between monthly affordability and total cost. If you can afford a 48 or 60-month term, that's usually the sweet spot for a used car—short enough that you're not paying excessive interest, long enough that the payment fits your budget. Avoid stretching beyond 72 months unless the car is very new or you have no other option.

Frequently Asked Questions

Why is my used car loan rate higher than my friend's, even though we have the same credit score?

The car itself makes a difference. If your car is older, has higher mileage, or is a model known for reliability problems, lenders charge more. Your friend's car might be newer, have lower mileage, or be a Toyota or Honda, which lenders see as lower-risk. The lender you chose also matters—credit unions and banks have different rate sheets.

Can I get a better rate if I put down a larger down payment?

Sometimes. A larger down payment reduces the amount you're borrowing, which lowers the lender's risk, and some lenders will offer a slightly better rate in return. However, the improvement is usually small—0.25 to 0.5 percentage points—and it's not may provide. Ask your lender before you commit to a down payment amount.

What happens to my rate if I buy a car that's older than the lender's usual limit?

Most lenders won't finance it at all. If a bank's cutoff is 10 years and the car is 11 years old, they'll decline. Some credit unions and subprime lenders will finance older cars, but they'll charge significantly more—often 2 to 5 percentage points higher—because the risk is much greater.

Is it better to finance through the dealership or get a loan from my bank first?

Getting pre-approved from your bank or credit union first gives you leverage. You know your rate and can walk away if the dealership can't beat it. Dealership financing is convenient, but dealers often mark up the rate they get from their lender, so you may pay more. Pre-approval is almost always the better starting point.

Does the color or condition of the car affect my interest rate?

Not directly. Lenders care about mechanical condition, age, mileage, and history—things that affect whether the car will run and hold its value. Paint color and interior wear don't change the rate. However, a car in poor condition might fail a pre-purchase inspection, which could delay or kill the loan.
