Used car loans work the same way as new car loans, but the vehicle's age and mileage affect your interest rate and what lenders will finance

A used car loan is money borrowed from a bank, credit union, or online lender to buy a vehicle that is not brand new. The lender holds the title until you pay off the loan. Because used cars depreciate more slowly than new ones and have unknown repair histories, lenders typically charge higher interest rates than they would for new vehicles. Your rate depends on the car's age, mileage, condition, your credit score, and how much money you put down.

The basic process is the same whether you buy used or new: you find a car, get pre-approved for a loan amount, negotiate the price, and sign loan documents. The main difference is that used cars come with more risk for the lender, so you may face stricter terms — a shorter loan length, a requirement to put down more money, or a higher interest rate.

Key Takeaways

  • Used car loans typically have higher interest rates than new car loans because the vehicle loses value faster and has an unknown repair history.
  • Getting pre-approved before you shop tells you your real budget and shows dealers you are a serious buyer.
  • Your credit score, the car's age and mileage, and how much you put down all directly affect the interest rate you receive.
  • Credit unions and online lenders often offer lower rates than dealership financing, so compare offers before you decide.

How interest rates are set for used vehicles

Lenders price used car loans based on how much risk they take on. A 2015 sedan with 80,000 miles is riskier than a 2022 sedan with 30,000 miles because it is more likely to need expensive repairs, and it will be worth less if the lender has to repossess it. That risk shows up as a higher interest rate.

Your credit score is the single biggest factor in your rate. A score above 700 typically unlocks rates in the 4 to 8 percent range for used cars, depending on the vehicle's age. A score below 600 may mean rates of 12 percent or higher. The amount you put down also matters: putting down 20 percent instead of 10 percent usually lowers your rate by half a percentage point or more. Loan length affects your rate too — a 36-month loan usually has a lower rate than a 72-month loan for the same car.

The car's age and mileage are hard cutoffs for many lenders. Most banks will not finance a car older than 10 years, and some stop at 7 years. Mileage limits vary, but 120,000 to 150,000 miles is common. If you find a car outside these ranges, you may only may have access to through a credit union, a buy-here-pay-here dealer, or a lender that specializes in older vehicles — and those rates will be much higher.

Where to get a used car loan

You have three main sources: banks, credit unions, and online lenders. Each has different strengths. Banks offer the widest range of loan amounts and terms, but their rates are usually higher than credit unions. Credit unions typically have the lowest rates if you are a member, but you must join first — membership rules vary by credit union. Online lenders approve quickly and work with lower credit scores, but their rates are often the highest of the three.

Dealership financing is a fourth option, but it is not a lender — the dealer arranges a loan with a bank or credit union and adds a markup. You will almost always get a better rate by bringing your own pre-approval to the dealership than by financing through them. The dealer's job is to sell cars, not to give you the best loan terms.

Start by getting pre-approved from at least two or three sources before you shop. Pre-approval means the lender has checked your credit and told you a loan amount and interest rate you would receive — it is not a binding commitment. Pre-approval letters are free and take 15 to 30 minutes online. Bring your pre-approval to the dealership; if the dealer's financing is better, you can use it, but you will have a backup offer and you will know your real budget.

What lenders need from you to approve a used car loan

Lenders ask for the same documents whether you buy used or new, but the used car itself gets more scrutiny. You will need a government-issued ID, proof of income (a recent pay stub or tax return), proof of residence (a utility bill or lease), and your Social Security number so they can pull your credit report. Some lenders also ask for bank statements to verify you have money for a down payment.

The car itself must pass a vehicle inspection — the lender will order a report that checks the title for liens or damage history, verifies the mileage, and confirms the vehicle exists and matches the description. This report costs $15 to $50 and usually takes one to three business days. If the car has a branded title (salvage, flood, or rebuilt), most mainstream lenders will decline it. If the mileage is significantly higher than what the seller claims, the lender may lower the loan amount or walk away.

You will also need the car's Vehicle Identification Number (VIN) before you explore. The VIN is a 17-character code on the driver's side of the windshield or on the title. The lender uses it to order the inspection report and to confirm the vehicle matches what you described in your process.

Down payments and loan terms for used cars

Most lenders want at least 10 percent down on a used car, though some will go as low as 5 percent if your credit score is strong. Putting down 20 percent or more significantly lowers your interest rate and reduces the amount you owe if the car is damaged or totaled. A larger down payment also means a smaller monthly payment and less total interest paid over the life of the loan.

Loan terms for used cars typically range from 36 to 72 months. A 36-month loan has a lower interest rate but a higher monthly payment. A 72-month loan spreads the cost over more months, so the payment is smaller, but you pay much more interest overall and you may owe more than the car is worth for several years. Most financial advisors recommend 48 to 60 months as a middle ground: the rate is reasonable, the payment is manageable, and you build equity faster.

Some lenders offer shorter terms for older used cars — a 2015 model might max out at 60 months, while a 2020 might go to 72. This is because the lender wants to be paid off before the car becomes too old to resell if they have to repossess it.

How to compare used car loan offers

When you have pre-approval offers from multiple lenders, compare them on three numbers: the interest rate, the loan term, and the total amount of interest you will pay. The interest rate alone is not enough — a lower rate on a 72-month loan might cost you more total interest than a slightly higher rate on a 60-month loan.

Use a loan calculator to see the monthly payment and total cost for each offer. Most lenders' websites have one built in, or you can find free calculators online. Plug in the loan amount, the interest rate, and the term in months. The calculator will show you the monthly payment and the total interest you will pay.

Also check whether the lender charges fees. Some charge an origination fee (1 to 2 percent of the loan amount), a documentation fee, or a prepayment penalty if you pay off the loan early. These fees add to your cost and should be factored into your comparison. Ask each lender for the total cost of the loan, including all fees, not just the interest rate.

What happens after you are approved

Once you choose a lender and are approved, you will sign loan documents. These include the promissory note (your promise to repay), the security agreement (giving the lender a lien on the car), and disclosures about the interest rate and fees. Read these carefully — they spell out your obligations and what happens if you miss a payment.

The lender will send the money to the seller or the dealership, and you will receive the title once the loan is paid off. Until then, the lender's name appears on the title as the lienholder. You must carry full-coverage car insurance (collision and comprehensive) while you owe money on the car — the lender will require this in the loan documents. If you let your insurance lapse, the lender can buy insurance for you and add the cost to your loan.

Your first payment is usually due 30 days after you sign the loan documents. Set up automatic payments if possible — it reduces the risk of missing a payment, which damages your credit and can lead to repossession.

Frequently Asked Questions

Can I get a used car loan with bad credit?

Yes, but your interest rate will be higher — often 12 to 18 percent or more. Online lenders and buy-here-pay-here dealers work with lower credit scores, but they charge the highest rates. A credit union may offer better terms if you are a member. Putting down a larger down payment can help offset a low credit score.

What if the car I want is older than 10 years?

Most traditional lenders will not finance cars older than 7 to 10 years. Your options are credit unions (which sometimes go older), online lenders that specialize in older vehicles, or buy-here-pay-here dealers. These lenders charge much higher interest rates because the risk is greater. You may also need to pay cash or find a co-signer.

Should I get a loan from the dealership or bring my own?

Bring your own pre-approval. Dealership financing includes a markup that increases your interest rate. Even if the dealer's rate looks competitive, you are usually better off using your pre-approval. The only exception is if the dealer offers a special promotional rate (0 percent, for example) that beats your pre-approval.

What is gap insurance and do I need it?

Gap insurance covers the difference between what you owe on the loan and what the car is worth if it is totaled. If you owe $15,000 and the car is worth $12,000, gap insurance pays the $3,000 gap. It is most useful if you put down less than 20 percent. Some lenders include it; others charge $500 to $1,000 for it. Ask whether it is included in your loan offer.

Can I pay off my used car loan early without a penalty?

Most lenders allow early payoff without penalty, but some charge a prepayment penalty of 1 to 2 percent of the remaining balance. Ask your lender before you sign — it should be spelled out in the loan documents. Paying off early saves you interest, so it is usually worth doing even if there is a small penalty.
