A used auto loan is a secured loan from a bank, credit union, or dealership that you use to buy a car that is not new

The lender holds the title to the car until you pay off the loan. Used auto loans typically have higher interest rates than new car loans because used vehicles depreciate faster and are considered riskier. The loan term usually runs from 36 to 72 months, though some lenders offer longer periods. Your monthly payment depends on the loan amount, the interest rate you receive, and how many months you choose to repay.

Unlike a personal loan, a used auto loan is secured — meaning the car itself backs the loan. If you stop making payments, the lender can repossess the vehicle. This is why used auto loans are often easier to obtain than unsecured loans, even if your credit score is not perfect.

Key Takeaways

  • Used auto loans charge higher interest rates than new car loans because the vehicle loses value faster and poses more risk to the lender.
  • Your interest rate depends mainly on your credit score, the age and mileage of the car, and how much money you put down as a down payment.
  • Lenders will inspect the vehicle's history through a report like Carfax or AutoCheck before approving the loan.
  • You can get a used auto loan from a bank, credit union, or dealership, and rates and terms vary significantly between them.
  • Pre-approval from a bank or credit union before visiting a dealership gives you negotiating power and lets you know your actual rate.

How your credit score affects the interest rate you receive

Your credit score is the single biggest factor in determining your interest rate on a used auto loan. Lenders use your score to predict whether you will pay on time. A score of 750 or higher typically qualifies you for the lowest rates. A score between 650 and 749 will result in a higher rate. A score below 650 may still allow you to borrow, but the rate will be substantially higher — sometimes 10 percent or more annually.

If your credit score is low, you have two options: wait a few months while you pay down existing debt and make on-time payments to raise your score, or accept a higher rate now and refinance later once your score improves. Some lenders specialize in borrowers with lower scores, but their rates reflect the added risk. A credit union membership can sometimes offer better rates than banks or dealerships, even with a lower score.

What lenders examine before approving a used auto loan

Beyond your credit score, lenders look at the vehicle itself. They will order a vehicle history report — usually Carfax or AutoCheck — to check for accidents, title problems, flood damage, or odometer rollback. A car with a clean history costs less to insure and holds its value better, so lenders view it as lower risk. A vehicle with accident history or a salvage title will either be declined or require a much higher interest rate.

Lenders also consider the age and mileage of the car. Most will not finance a vehicle older than 10 to 15 years, depending on the lender and the loan term you want. A car with very high mileage (over 150,000 miles) may be declined or require a shorter loan term. The loan-to-value ratio — how much you are borrowing compared to what the car is worth — also matters. If you are borrowing more than the car is worth, some lenders will decline you or require a larger down payment.

The difference between bank, credit union, and dealership loans

Banks offer used auto loans with competitive rates if your credit is good, but they may decline you if your score is below 620. The approval process usually takes one to three business days. Banks typically finance vehicles up to 10 years old and require a down payment of at least 10 percent.

Credit unions often have lower rates than banks and are more flexible with credit scores, especially if you are a member. Some credit unions will finance older vehicles or those with higher mileage. The trade-off is that credit unions may have fewer locations and slower approval times. You must be a member to borrow, though some allow you to join before explore.

Dealership financing is the fastest option — you can drive off the lot the same day — but the interest rate is usually the highest of the three. Dealerships work with multiple lenders behind the scenes and take a cut of the interest, which raises your rate. Dealership loans are useful if you have been declined elsewhere, but you should always compare the rate to what a bank or credit union offers first.

How to get pre-approved before shopping for a car

Pre-approval means a lender has reviewed your credit and finances and told you the maximum loan amount and interest rate you may have access to for. You can get pre-approved at a bank or credit union in person or online, usually within 24 hours. Pre-approval does not lock you into that lender — it is straightforward a conditional offer that shows you what you can afford.

Pre-approval gives you three advantages. First, you know your actual interest rate before you walk into a dealership, so you can compare it to what the dealer offers. Second, you can negotiate the car price without the pressure of dealership financing. Third, if the dealership's rate is higher, you can decline and use your pre-approval instead. Many dealerships will match or beat a pre-approval rate to keep the sale, but only if you show them the offer in writing.

Down payment, loan term, and monthly payment basics

A down payment reduces the amount you borrow and lowers your monthly payment and total interest cost. Most lenders require a down payment of 10 to 20 percent of the car's purchase price. A larger down payment — 30 percent or more — can lower your interest rate because it reduces the lender's risk. If you have limited savings, a smaller down payment is possible, but your rate will be higher.

Loan terms for used cars typically 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 over more months, lowering your payment, but you pay significantly more in interest overall. A 60-month loan is common because it balances affordability with reasonable total interest cost.

Your monthly payment is calculated using the loan amount, interest rate, and term. For example, a $20,000 loan at 6 percent interest over 60 months costs roughly $387 per month. The same loan at 8 percent costs about $405 per month. A few percentage points in interest rate can add hundreds of dollars to your total cost, which is why shopping around for the best rate matters.

What happens after you are approved and sign the loan agreement

Once you are approved, you will sign a loan agreement that lists the loan amount, interest rate, monthly payment, term, and any fees. Read this document carefully — it should match what you were quoted. Some dealerships add fees like documentation, dealer prep, or extended warranty that were not discussed. You have the right to ask about any fee and decline add-ons you do not want.

After you sign, the lender pays the seller or dealership directly. You receive the car and the title, which the lender holds as collateral. You will make your first payment 30 days after the loan closes. If you pay late, the lender will charge a late fee and report it to the credit bureaus, which damages your credit score. Some lenders offer automatic payment from your bank account, which can lower your interest rate slightly and ensures you never miss a due date.

Frequently Asked Questions

Can I get a used auto loan with bad credit?

Yes, but the interest rate will be higher. Credit unions and some banks specialize in borrowers with scores below 620. Dealership financing is also an option, though rates are typically the highest. A larger down payment or a co-signer with better credit can improve your chances of approval and lower your rate.

What is the difference between pre-approval and pre-qualification?

Pre-qualification is a rough estimate based on information you provide; it is not verified and does not may provide a loan. Pre-approval involves a hard credit check and verification of your income and debts, so it is a real conditional offer. Pre-approval carries more weight when negotiating with a dealership.

Can I refinance a used auto loan later?

Yes. If your credit score improves or interest rates drop, you can refinance to a lower rate. Refinancing replaces your old loan with a new one, usually with a new lender. You will pay closing costs, so refinancing makes sense only if the new rate is at least 1 to 2 percent lower than your current rate.

What if the car breaks down shortly after I buy it?

You are still responsible for the loan payments. Used cars are sold as-is unless the dealer offers a warranty. Some dealerships include a short warranty (30 to 90 days) on used vehicles. Before buying, have a mechanic inspect the car to catch problems early. Gap insurance can cover the difference between what you owe and what the car is worth if it is totaled, but it does not cover repairs.

How much should I spend on a used car?

A common rule is to spend no more than 10 to 15 percent of your annual gross income on a car. If you earn $50,000 per year, a $5,000 to $7,500 car fits this guideline. This leaves room for insurance, maintenance, and fuel without straining your budget. Your monthly car payment should not exceed 15 to 20 percent of your monthly take-home pay.
