What a car loan is and how it works

A car loan is money a bank, credit union, or other lender gives you to buy a vehicle. You agree to pay back the full amount plus interest over a set period — usually 36 to 72 months. The lender holds the title to the car until you finish paying, which means they can repossess it if you stop making payments.

The monthly payment you make covers a portion of the principal (the amount you borrowed) and interest (the cost of borrowing). Early in the loan, most of your payment goes toward interest. As time passes, more goes toward principal. This is why paying off a loan early can save you significant money in interest.

The interest rate you receive depends on your credit score, the size of your down payment, the age and type of vehicle, and current market rates. A stronger credit history typically means a lower rate. The loan term also affects your rate — a 36-month loan usually has a lower rate than a 72-month loan, but your monthly payment will be higher.

Key Takeaways

  • Your credit score is the single biggest factor in the interest rate you receive, so checking your score before shopping for a loan can help you understand what rate to expect.
  • A larger down payment reduces the amount you borrow and can lower your interest rate, because the lender's risk decreases.
  • Loan terms range from 36 to 72 months or longer, and choosing a longer term lowers your monthly payment but increases total interest paid.
  • You can get a car loan from a bank, credit union, or the dealership itself, and shopping with multiple lenders before buying can save you hundreds of dollars.
  • The lender holds the car's title until the loan is paid off, and they can repossess the vehicle if you miss payments.

How your credit score affects the loan you receive

Lenders use your credit score to decide whether to lend to you and what interest rate to charge. Your score reflects your history of paying bills on time, how much debt you currently carry, and how long you have had credit accounts open. Scores typically range from 300 to 850, with higher scores indicating lower risk to the lender.

If your score is above 700, most lenders consider you a lower-risk borrower and will offer competitive rates. If your score is between 600 and 700, you may still receive a loan, but the rate will be higher. Below 600, some lenders will decline you entirely, while others will offer loans at significantly higher rates. The difference between a 650 score and a 750 score can mean paying thousands of dollars more in interest over the life of the loan.

You can check your credit score for free through AnnualCreditReport.com, which is the official site for the three major credit bureaus (Equifax, Experian, and TransUnion). Many banks and credit card companies also provide free score monitoring. Knowing your score before you shop for a loan helps you understand what rate range to expect and whether you should work on improving your score before explore.

Down payments and how they change your loan

A down payment is money you pay upfront toward the vehicle purchase. It reduces the amount you need to borrow, which lowers your monthly payment and the total interest you pay. A typical down payment ranges from 10% to 20% of the vehicle's price, though some people put down more and some put down less.

If you put down $5,000 on a $25,000 car, you borrow $20,000. If you put down $2,500, you borrow $22,500. Over a 60-month loan at 6% interest, that extra $2,500 borrowed costs you roughly $330 more in interest alone. Lenders also view a larger down payment as a sign that you are committed to the purchase and less likely to default, which can result in a lower interest rate.

Some people finance 100% of the vehicle price (called "zero down"), but this is riskier for the lender and usually results in a higher rate. If you are considering a car loan and have savings available, putting down even a modest amount can meaningfully reduce your costs.

Where to get a car loan

You have three main sources for car loans: banks, credit unions, and dealerships. Each has different strengths, and comparing offers from all three before you buy can save you money.

Banks are traditional lenders that offer car loans to customers with a wide range of credit scores. They typically have competitive rates for borrowers with good credit, but may charge higher rates for those with lower scores. You can explore online or in person, and approval usually takes a few days.

Credit unions are member-owned financial institutions that often offer lower rates than banks, especially for members with average credit. If you belong to a credit union, check their rates before shopping elsewhere. If you do not belong to one, some credit unions allow you to join based on where you work, where you live, or family connections. Credit unions also tend to be more flexible with borrowers who have recent credit problems.

Dealerships can arrange financing directly through their lenders or through banks and credit unions they work with. The convenience of financing at the dealership is appealing, but dealership rates are often higher than what you could get by shopping on your own. Dealerships also sometimes add fees or extended warranties to the loan. If you finance through a dealership, always ask for the interest rate in writing and compare it to offers from at least one bank or credit union.

Loan terms and monthly payments

The loan term is how long you have to pay back the money — typically 36, 48, 60, or 72 months. A shorter term means a higher monthly payment but less interest paid overall. A longer term means a lower monthly payment but more interest paid overall.

On a $20,000 loan at 6% interest, a 36-month term results in a monthly payment of roughly $600 and total interest of about $1,700. A 60-month term results in a monthly payment of roughly $387 and total interest of about $3,200. A 72-month term results in a monthly payment of roughly $333 and total interest of about $4,000. The choice depends on your budget and how long you plan to keep the car.

Longer-term loans also carry more risk for the lender because the car depreciates (loses value) over time. By the end of a 72-month loan, the car may be worth less than what you still owe on it. This is called being "underwater" on the loan. For this reason, lenders often charge higher interest rates for longer terms. When comparing loan offers, always look at the total interest cost, not just the monthly payment.

What happens if you miss payments or want to pay off early

If you miss a car loan payment, the lender will typically contact you within a few days. Missing one payment usually results in a late fee and a note on your credit report. Missing multiple payments — usually three or more — can lead to repossession, where the lender takes the car back. Repossession damages your credit score significantly and makes it much harder to borrow money in the future.

If you are struggling to make a payment, contact your lender when ready. Many lenders offer options like deferment (skipping a payment and adding it to the end of the loan) or loan modification (changing the terms). Acting early gives you more options than waiting until you are behind.

If you want to pay off the loan early — for example, if you receive a bonus or inheritance — most lenders allow this without penalty. Paying off early saves you interest. Before making extra payments, confirm with your lender that there is no prepayment penalty, and ask whether extra payments go toward principal or are held as a credit toward future payments.

Frequently Asked Questions

What credit score do I need to get a car loan?

Most lenders will work with borrowers who have a score of 600 or higher, though rates are significantly better above 700. Some credit unions and specialized lenders will consider scores below 600, but rates will be much higher. If your score is below 600, you may have better luck with a credit union or by adding a co-signer with stronger credit.

Can I get a car loan with no credit history?

Yes, but it is more difficult. Lenders have no record of how you handle debt, so they see you as higher risk. A co-signer (someone who agrees to pay if you do not) can help. A larger down payment also makes you more attractive to lenders. Credit unions are often more willing to work with people who have no credit history than traditional banks are.

Should I get a loan before or after I find the car?

Getting pre-approved for a loan before you shop gives you a clear budget and stronger negotiating power at the dealership. You know exactly what rate and term you may have access to for, so you can compare any dealership offer to that baseline. Pre-approval also shows the dealership you are a serious buyer.

What is the difference between a fixed and variable interest rate?

Most car loans have a fixed rate, meaning your interest rate and monthly payment stay the same for the entire loan. Some lenders offer variable rates that can change based on market conditions, but these are less common for car loans. A fixed rate is simpler and more predictable, so it is usually the better choice.

Can I refinance my 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, you can refinance. This means taking out a new loan to pay off the old one. Refinancing can lower your monthly payment or shorten your loan term. Contact your bank or credit union to ask about refinancing options, and compare offers from multiple lenders before deciding.
