A car loan is money a bank or credit union lends you to buy a vehicle, which you repay in monthly installments over a set period, usually three to seven years.
The lender holds the title to the car until you finish paying. You make a down payment upfront—typically 10 to 20 percent of the purchase price—and borrow the rest. The lender charges interest, a percentage of the loan amount that becomes part of your monthly payment. Your payment stays the same each month (for fixed-rate loans), making it predictable to budget.
The interest rate you receive depends on your credit score, income, the loan term you choose, and the lender's policies. A higher credit score usually means a lower rate. The loan term—how many months you have to repay—affects both your monthly payment and the total interest you pay. A shorter term means higher monthly payments but less interest overall; a longer term spreads payments out but costs more in interest.
Key Takeaways
- Your monthly payment covers both principal (the amount borrowed) and interest, with the interest portion highest at the start of the loan.
- Interest rates vary based on your credit score, income, down payment size, and the lender's underwriting standards.
- Loan terms typically range from 36 to 84 months, and choosing a shorter term reduces total interest paid but raises your monthly payment.
- The lender holds the car's title as collateral until the loan is paid off, meaning they can repossess the vehicle if you miss payments.
- Pre-approval from a bank or credit union before shopping gives you a clear budget and negotiating power at the dealership.
How lenders decide your interest rate
Banks and credit unions use several factors to set your rate. Your credit score is the primary one—it reflects your history of paying bills on time. Scores typically range from 300 to 850; a score above 700 usually qualifies for competitive rates, while scores below 620 face higher rates or may be declined. Lenders also check your debt-to-income ratio, which compares your monthly debt payments to your gross monthly income. If you already carry high credit card balances or other loans, a lender may see you as riskier and charge more.
The size of your down payment matters too. A larger down payment reduces the amount you need to borrow, lowering the lender's risk. The age and mileage of the car you're buying affect the rate—new cars typically get lower rates than used ones because they hold value better. Your employment history and whether you've had previous car loans also factor in. A lender wants to see stable income and a track record of repaying vehicle loans on time.
The difference between new and used car loans
New car loans usually carry lower interest rates because new vehicles depreciate more slowly and are easier to repossess and resell if needed. Banks view them as lower risk. New car loans also tend to have longer terms available—up to 84 months—which spreads payments out over more time.
Used car loans come with higher interest rates because the vehicle has already lost value and may have unknown mechanical issues. Most lenders cap used car loans at 72 or 84 months depending on the car's age and mileage. A car that's more than 10 years old or has over 100,000 miles may be harder to finance through traditional lenders; credit unions sometimes offer better terms for older vehicles than banks do. Some lenders won't finance cars older than a certain year or with mileage above a threshold.
Where to get a car loan
You have three main sources: banks, credit unions, and dealership financing. Banks offer competitive rates if you have good credit, and you can shop rates from multiple banks before buying the car. Credit unions often have lower rates than banks, especially if you're a member, and they may be more flexible with borrowers who have fair credit or shorter employment history. Dealership financing is convenient because the dealer arranges the loan while you're buying the car, but rates are often higher than what you'd get from a bank or credit union directly.
Getting pre-approved before you shop is the strongest position. When you approach a bank or credit union for pre-approval, they check your credit and income, then tell you the maximum amount you can borrow and the rate you'll receive. You then know your budget and can negotiate with the dealer from a position of strength. If the dealer offers financing, you can compare their rate to your pre-approval rate and choose the better option.
What happens during the loan process
After you and the lender agree on terms, the lender conducts a final verification of your income and credit, then funds the loan. The money goes directly to the seller or dealership. You receive the loan documents, which spell out the monthly payment amount, the interest rate, the loan term, and what happens if you miss a payment. The lender files a lien against the car's title, which means they have a legal claim to the vehicle until the loan is paid off.
You make monthly payments to the lender, either by automatic bank transfer, check, or online payment. Early in the loan, most of your payment goes toward interest; as time passes, more goes toward the principal. If you pay extra toward principal or pay off the loan early, you reduce the total interest you pay. Once you make the final payment, the lender releases the lien and sends you the title, making you the full owner.
What to watch for in loan terms
Read the loan agreement carefully before signing. Check whether the rate is fixed (stays the same for the life of the loan) or variable (can change)—most car loans are fixed, which is preferable because your payment won't surprise you. Look for any prepayment penalties, which some lenders charge if you pay off the loan early; most car loans don't have them, but it's worth confirming.
Understand what happens if you miss a payment. Most lenders allow a grace period of 10 to 15 days after the due date before charging a late fee. If you miss multiple payments, the lender can repossess the car. Check whether the loan requires gap insurance, which covers the difference between what you owe and what the car is worth if it's totaled or stolen. Some lenders require it; others offer it as an option. Also confirm whether you must carry comprehensive and collision insurance on the vehicle—most lenders require it as a condition of the loan.
How to improve your chances of getting a better rate
If your credit score is below 700, work on paying down existing debt and making all payments on time for several months before explore for a car loan. Even a small improvement in your score can lower your rate. A larger down payment—20 percent or more—signals commitment and reduces the lender's risk, often resulting in a better rate.
Shopping with multiple lenders matters. Each inquiry into your credit within a 14-day window counts as a single inquiry, so you can get quotes from several banks and credit unions without damaging your score. Compare not just the interest rate but the total cost of the loan over its full term. A slightly higher rate on a shorter loan might cost less overall than a lower rate on a longer loan. If your credit is fair, a credit union may offer better terms than a bank, so check both.
Frequently Asked Questions
What's the difference between APR and interest rate on a car loan?
The interest rate is the percentage charged on the loan amount. The APR (annual percentage rate) includes the interest rate plus other costs like origination fees, and it gives you a fuller picture of what the loan actually costs. Lenders must disclose both, and comparing APRs across lenders is more accurate than comparing interest rates alone.
Can I get a car loan with bad credit?
Yes, but you'll pay a higher interest rate. Credit unions and some banks specialize in loans for borrowers with credit scores below 620. A larger down payment and a co-signer with better credit can improve your chances and lower your rate. Expect rates to be several percentage points higher than what someone with good credit would receive.
What happens if I can't make a payment?
Contact your lender when ready. Many offer temporary payment deferrals or loan modifications if you're facing hardship. Missing payments damages your credit and can lead to repossession after several missed payments. The longer you wait to communicate with the lender, the fewer options you'll have.
Should I pay off my car loan early?
Paying extra toward principal reduces the total interest you pay and shortens the loan term. If your loan has no prepayment penalty, paying early is usually financially smart. However, if you have high-interest credit card debt, paying that down first may save you more money overall.
Is it better to finance through the dealer or a bank?
Getting pre-approved through a bank or credit union first gives you a benchmark rate and keeps you from overpaying at the dealership. If the dealer's rate is lower, you can accept it; if it's higher, you can decline and use your pre-approval. This approach puts you in control rather than relying on the dealer's financing options.
