Used car loans are structured the same way as new car loans, but lenders assess the vehicle's condition and your ability to repay differently

When you borrow money to buy a used car, the lender places a lien on the vehicle's title — meaning they own it until you pay off the loan. The interest rate you receive depends on your credit score, the age and mileage of the car, how much you put down, and the loan term you choose. A used car typically costs more to finance than a new one because the vehicle depreciates faster, which means the car's value can drop below what you still owe on the loan.

Most used car loans run between 36 and 72 months. Shorter terms mean higher monthly payments but less total interest paid. Longer terms lower your monthly payment but cost more overall and carry greater risk that you'll owe more than the car is worth — a situation called being "underwater" on the loan.

Used car loans come from banks, credit unions, and captive finance companies (lenders owned by car dealerships). Each charges different rates and has different requirements. Credit unions typically offer the lowest rates to members, while dealership financing is often the fastest to obtain but may carry higher rates.

Key Takeaways

  • Used car loans are secured by the vehicle itself, so the lender can repossess the car if you stop making payments.
  • Your interest rate depends primarily on your credit score, the car's age and condition, your down payment amount, and the loan term you select.
  • Used cars depreciate faster than new cars, which means you can owe more than the vehicle is worth if you finance too much or choose too long a term.
  • Credit unions usually offer lower rates than banks or dealership financing, but you must be a member to borrow from them.
  • Getting pre-approved for a loan before you shop gives you negotiating power and lets you know your actual budget.

How lenders decide what rate to offer you

Your credit score is the single largest factor in your interest rate. A score above 700 typically qualifies you for rates in the 4 to 6 percent range at banks and credit unions. A score between 600 and 700 may result in rates between 7 and 12 percent. Scores below 600 often mean rates above 12 percent or outright denial.

The second factor is the vehicle itself. Lenders use the car's age, mileage, and condition to estimate how long it will last and how much it will be worth when you sell it or trade it in. A 2019 sedan with 60,000 miles will receive better terms than a 2015 sedan with 120,000 miles, even if you have the same credit score. Some lenders set hard limits — for example, they may not finance cars older than 10 years or with more than 150,000 miles.

Your down payment also affects the rate. Putting down 20 percent or more reduces the lender's risk and often lowers your rate by 0.5 to 1 percent. A smaller down payment — or none at all — signals higher risk and results in a higher rate.

Loan term matters too. A 36-month loan carries less risk than a 72-month loan because you pay it off faster and the car depreciates less during the repayment period. Lenders often offer lower rates for shorter terms.

The difference between pre-approval and in-dealership financing

Pre-approval means a lender has reviewed your credit and income and agreed to lend you a specific amount at a specific rate, usually valid for 30 to 60 days. You can then shop for a car within that budget and negotiate the price knowing exactly what you can afford and what your rate will be.

In-dealership financing skips pre-approval. You find a car, agree on a price, and then the dealership's finance manager arranges a loan through their lender network. This is faster but gives you less control. The rate you receive may be higher than your pre-approval rate, and you may not know the final terms until you're signing paperwork.

Some dealerships use a practice called "spot delivery," where you drive the car home before the financing is finalized. If the lender later rejects the loan or offers worse terms, the dealership may ask you to return the car or renegotiate. This creates risk for you, so read any paperwork carefully and confirm that financing is actually complete before you leave the lot.

Why used cars cost more to finance than new cars

A new car loses 20 to 30 percent of its value in the first year and continues depreciating. A used car has already taken that initial hit, but it still depreciates — just more slowly. The problem is that if you finance a used car over a long term, the car's value can fall below the loan balance.

For example, if you buy a $15,000 used car with a $3,000 down payment and finance $12,000 over 72 months, the car might be worth only $8,000 after three years — but you still owe $6,000. If the car is totaled in an accident, your insurance payout may not cover what you owe, leaving you responsible for the difference.

To protect themselves, lenders charge higher rates on used cars and often require gap insurance, which covers the difference between what you owe and what the car is worth if it's totaled. Some lenders also require a larger down payment on used cars than on new ones.

Where to get a used car loan

Credit unions typically offer the lowest rates if you are a member. Many credit unions have used car loan programs with rates starting around 4 to 5 percent for borrowers with good credit. You can join some credit unions based on where you work, where you live, or through membership organizations.

Banks offer used car loans but usually at rates 1 to 3 percent higher than credit unions. Large national banks like Chase and Bank of America have online pre-approval tools that show you a rate estimate within minutes. Regional and local banks sometimes offer better rates than national chains.

Online lenders such as LendingClub, Upstart, and Lightstream specialize in personal loans that can be used for car purchases. These are unsecured loans, meaning the lender does not hold a lien on the car, so rates are typically higher — often 8 to 15 percent — but you have more flexibility if you want to refinance or pay off early.

Dealership financing is the fastest option but often the most expensive. Dealerships work with multiple lenders and can sometimes offer competitive rates, especially if you have good credit. However, they also earn a commission on the loan, which incentivizes them to steer you toward higher rates or longer terms.

What happens if you owe more than the car is worth

Being underwater on a loan means the car's market value is less than what you still owe. This creates problems if you want to sell the car or trade it in before the loan is paid off. You would have to pay the difference out of pocket to clear the title.

If the car is totaled in an accident, your insurance company pays the car's current market value, not what you owe. If you owe $8,000 and the car is worth $6,000, you lose $2,000. Gap insurance covers this loss, but it costs extra — usually $500 to $1,000 added to your loan or paid upfront.

To avoid being underwater, put down at least 20 percent, choose a loan term no longer than 60 months, and buy a car that holds its value well. Certified pre-owned vehicles (CPO cars) typically depreciate more slowly than non-certified used cars because they come with a warranty and have passed an inspection.

How to compare loan offers from different lenders

When comparing offers, look at the annual percentage rate (APR), not just the interest rate. The APR includes the interest rate plus fees and gives you the true cost of borrowing. A loan with a 5 percent APR is cheaper than one with a 5.5 percent APR, even if the monthly payment looks similar.

Calculate the total amount you will pay over the life of the loan by multiplying your monthly payment by the number of months. A $300 monthly payment over 60 months costs $18,000 total; over 72 months it costs $21,600. The extra $3,600 is interest and fees.

Check whether the loan has a prepayment penalty — a fee charged if you pay off the loan early. Most used car loans do not, but some do. If you plan to refinance or pay off the loan ahead of schedule, confirm there is no penalty.

Get offers from at least three lenders before deciding. Soft inquiries (pre-approval checks) do not hurt your credit score, but hard inquiries do. Multiple hard inquiries within 14 to 45 days count as a single inquiry for credit scoring purposes, so shop around within a short window.

Frequently Asked Questions

Can I get a used car loan with bad credit?

Yes, but you will pay a higher interest rate — often 12 to 18 percent or more. Some lenders specialize in bad-credit auto loans, but they may require a larger down payment or a co-signer. Credit unions sometimes offer better rates for bad-credit borrowers than traditional banks.

What is the difference between a secured and unsecured auto loan?

A secured loan uses the car as collateral, so the lender can repossess it if you stop paying. Most auto loans are secured. An unsecured loan does not use the car as collateral, so rates are higher but you keep the car even if you default. Personal loans used for car purchases are usually unsecured.

Should I buy gap insurance when financing a used car?

Gap insurance is worth considering if you are financing more than 80 percent of the car's value, choosing a loan term longer than 60 months, or buying a car that depreciates quickly. If you are putting down 20 percent or more and financing for 48 months or less, gap insurance is usually unnecessary.

Can I refinance a used car loan to a lower rate?

Yes, if your credit score has improved or interest rates have dropped since you took out the original loan. Refinancing typically takes 30 to 45 days and involves a new hard inquiry on your credit. Make sure the new loan does not extend your payoff date so far that you end up underwater again.

What should I do if the dealership says I was approved but the lender later rejects the loan?

This can happen with spot delivery. Contact the dealership when ready and ask them to work with the lender to find a solution — a higher down payment, a co-signer, or a different lender. Do not accept terms much worse than what you originally agreed to. You have the right to walk away and return the car if the financing falls through.
