Used car loans are installment loans from banks, credit unions, or dealerships that let you buy a car you don't own outright

A used car loan works the same way as a new car loan: you borrow money, the lender puts a lien on the car (meaning they own it until you pay off the loan), and you make monthly payments with interest. The main difference is that used cars depreciate more slowly than new ones after the first few years, so your loan balance and the car's value stay closer together. This matters because if you default, the lender can repossess and sell the car, and you're responsible for any gap between what they get and what you still owe.

Lenders care more about your credit score and income for a used car loan than they do for a new one, because used cars are riskier collateral. A used 2019 Honda Civic might be worth $16,000 today and $14,000 next year. If you stop paying after six months, the lender's $15,000 loan is now backed by a car worth less than they're owed. Banks price this risk into your interest rate — the worse your credit, the higher your rate.

Key Takeaways

  • Used car loans require a down payment (typically 10 to 20 percent of the car's price), proof of income, and a credit check, and the lender will place a lien on the car until you pay it off.
  • Your interest rate depends mainly on your credit score, the loan term (36 to 72 months is common), and the car's age and mileage, not on where you buy the car.
  • Credit unions often offer lower rates than banks or dealership financing, but you must be a member and the process takes longer.
  • Getting pre-approved for a loan before you shop gives you a firm budget and negotiating power, and lets you walk away from dealership financing offers.
  • Used cars older than 10 years or with more than 120,000 miles are harder to finance and carry higher interest rates because lenders see them as riskier.

Where to get a used car loan

You have three main sources: banks, credit unions, and dealerships. Banks are the most common — you walk in or go online, provide income and credit information, and get approved for a loan amount. The bank then gives you a check or transfers money to buy the car from any seller. Credit unions work the same way but usually offer lower rates if you've been a member for at least a few months; the tradeoff is that the process is slower and you must be a member. Dealerships offer financing directly, which is fast and convenient but almost always costs more because the dealership marks up the interest rate.

Pre-approval from a bank or credit union before you shop is the strongest position. You'll know exactly how much you can borrow, what your rate will be, and you can negotiate the car's price without the dealer knowing your financing is already locked in. If the dealership offers you financing, you can compare it to your pre-approval and walk away if it's worse. Many buyers skip this step and regret it — dealership rates are often 2 to 4 percentage points higher than what you could have gotten from a bank.

What lenders check before approving you

Lenders pull your credit report and score, verify your income (usually with recent pay stubs or tax returns), and check your debt-to-income ratio — how much you already owe each month compared to what you earn. They also run a soft inquiry that doesn't hurt your credit. If you have no credit history, a co-signer with good credit can help you get approved, though they're responsible for the loan if you don't pay.

The car itself matters too. Lenders use the vehicle identification number (VIN) to check the car's age, mileage, and history. Most lenders won't finance cars older than 10 years or with more than 120,000 miles because they're more likely to break down and become worthless before the loan is paid off. Some lenders have stricter limits — a few won't go past 8 years or 100,000 miles. If the car you want is older or has high mileage, call lenders before you make an offer, because you may not be able to finance it at all.

How interest rates and loan terms work

Your interest rate is set by the lender based on your credit score, the loan term, and the car's age and mileage. A borrower with a 750 credit score might get 4.5 percent on a 60-month loan for a 2019 car with 60,000 miles. The same car, same term, but a 650 credit score might be 8.5 percent. A 2015 car with 100,000 miles might add another 1 to 2 percentage points. Rates vary by lender, so it's worth calling three or four to compare.

Loan terms range from 36 to 72 months. A shorter term (36 to 48 months) means higher monthly payments but less total interest paid. A longer term (60 to 72 months) spreads the cost out but you pay more interest overall. For a used car, 60 months is common because the car is already a few years old and may need repairs before the loan is done. If you stretch to 72 months, make sure the car's warranty or your own savings can cover repairs, because you'll still be paying for a car that's 8 to 9 years old.

Down payments and what happens at closing

Most lenders require a down payment of 10 to 20 percent of the car's purchase price. A $15,000 car typically needs $1,500 to $3,000 down. The down payment reduces the amount you borrow, which lowers your monthly payment and the total interest you pay. It also protects the lender — if you put down 20 percent and the car depreciates, the lender's loan is still backed by the car's value.

At closing, you'll sign loan documents, provide proof of insurance (lenders require full coverage, not just liability), and the lender will file the lien with your state's motor vehicle department. This takes a few days to a week. You get the title once the loan is paid off; until then, the lender holds it. If you sell the car before the loan is paid off, you'll need to pay off the loan first, or the new buyer will need to take over the loan (which most lenders don't allow).

Used car loans with bad credit or no credit history

If your credit score is below 620, most traditional lenders won't approve you. Your options are a credit union (which sometimes has more flexible standards), a subprime lender (which specializes in bad credit but charges much higher rates, often 15 to 29 percent), or a co-signer. A co-signer is someone with good credit who signs the loan with you and is legally responsible if you don't pay. This is risky for the co-signer, so choose someone you trust.

If you have no credit history, a credit union or a lender that uses alternative data (like rent and utility payments) may work. Some dealerships also work with subprime lenders, but the rates are high. Building credit before you buy — by getting a secured credit card or becoming an authorized user on someone else's account — takes time but will save you thousands in interest.

Common mistakes to avoid

The biggest mistake is not getting pre-approved. Dealerships count on you not knowing your options, and they'll offer you financing at a rate you could have beaten by 2 to 4 percentage points. Another mistake is stretching the loan term too long to lower the monthly payment. A 72-month loan on a used car means you're paying for a car that's 8 to 9 years old, and repair costs will likely spike in years 5 and 6. A shorter term costs more per month but protects you.

Don't skip the pre-purchase inspection. A mechanic's inspection costs $100 to $200 and can reveal problems that will cost thousands to fix. If the lender won't finance the car because of its age or mileage, that's a signal to walk away — the lender knows the car is risky. Finally, don't buy gap insurance from the dealership unless you're putting down less than 10 percent. Gap insurance covers the difference between what you owe and what the car is worth if it's totaled, but it's overpriced at dealerships and often included in credit union loans.

Frequently Asked Questions

Can I get a used car loan with a credit score below 600?

Traditional banks and credit unions will likely decline you. Subprime lenders will approve you but charge 15 to 29 percent interest, which makes the loan very expensive. A co-signer with good credit can help you get approved at a better rate, or you can wait a few months to build your credit score by paying bills on time and reducing debt.

What's the difference between financing through a bank and through the dealership?

Banks and credit unions set their own rates based on your credit and the car's details. Dealerships often buy loans from banks or subprime lenders and mark up the rate by 1 to 4 percentage points for profit. Getting pre-approved from a bank lets you compare and reject the dealership's offer if it's worse.

How old can a used car be and still get financed?

Most lenders won't finance cars older than 10 years, and some stop at 8 years. Mileage matters too — 120,000 miles is a common cutoff. If the car is older or has higher mileage, call lenders before you make an offer. Some will finance it at a higher rate; others won't finance it at all.

What if I want to pay off the loan early?

Most lenders allow early payoff with no penalty. Paying off early saves you interest, but make sure the lender doesn't charge a prepayment penalty — ask before you sign. Once the loan is paid off, the lender will release the lien and send you the title.

Do I need full coverage insurance to get a used car loan?

Yes. Lenders require full coverage (collision and comprehensive) until the loan is paid off because they own the car. Once you own it outright, you can drop to liability-only if you choose, though that's riskier if you're in an accident.
