What a car loan is and how it works
A car loan is money a bank or credit union lends you to buy a vehicle. You repay that money in monthly installments over a set period — typically three to seven years — plus interest. The lender holds the title to the car until you pay off the loan completely, which means they have a legal claim to the vehicle if you stop making payments.
The process is straightforward: you find a car, the lender pays the dealer, and you owe the lender. Your monthly payment covers both principal (the amount borrowed) and interest (the lender's fee for lending). The interest rate you receive depends on your credit score, the loan term you choose, and the lender's current rates.
Unlike a lease, where you rent a car for a few years, a loan ends with you owning the vehicle outright. This means you keep the car after the loan is paid off, but you also pay for all maintenance and repairs once any manufacturer warranty expires.
Key Takeaways
- A car loan is borrowed money you repay monthly with interest, and the lender legally owns the car until you finish paying.
- Your interest rate depends mainly on your credit score, so checking your credit before shopping can help you understand what rate to expect.
- You can get a car loan from a bank, credit union, or the dealership itself, and rates and terms vary significantly between lenders.
- The loan term (how many months you have to repay) affects both your monthly payment and the total interest you pay over time.
- You must have a down payment ready, proof of income, a valid driver's license, and proof of insurance before the lender will fund the loan.
How your credit score affects the loan you receive
Your credit score is the single biggest factor in determining your interest rate. Lenders use it to estimate how likely you are to repay on time. A score of 750 or higher typically qualifies you for the lowest rates available. A score between 650 and 749 will result in a higher rate. Below 650, you may face significantly higher rates or be turned down entirely.
You can check your own credit score for free through AnnualCreditReport.com, which is the only federally authorized site for free reports. Knowing your score before you shop for a loan helps you understand what rate range to expect and whether it makes sense to wait and improve your score before borrowing.
If your score is lower than you'd like, some lenders specialize in loans for people with poor or limited credit history, though their rates will be higher. A co-signer with better credit can sometimes lower your rate, but they become legally responsible for the loan if you don't pay.
Where to get a car loan and what to compare
You have three main sources: banks, credit unions, and dealerships. Banks offer competitive rates if you have good credit, but the process takes longer. Credit unions typically offer lower rates to members and are more flexible with credit requirements. Dealerships offer convenience — you can arrange financing while buying the car — but their rates are often higher because they're marking up the lender's rate.
The smartest approach is to get pre-approved by a bank or credit union before you visit a dealership. Pre-approval means the lender has reviewed your finances and offered you a specific rate and loan amount. You then shop for cars knowing exactly what you can afford and what rate you're getting, which gives you negotiating power at the dealership.
When comparing loans, look at three numbers: the interest rate, the loan term in months, and the total amount you'll pay over the life of the loan. A lower rate saves you thousands of dollars, but a longer term means lower monthly payments. A 60-month loan at 5% costs more in total interest than a 36-month loan at the same rate, even though your monthly payment is smaller.
Documents and information you'll need to provide
Lenders require proof that you can repay the loan. Have these documents ready before you explore: two recent pay stubs or proof of income, a recent tax return if you're self-employed, a valid driver's license, and proof of insurance (you must insure the car before the lender will fund the loan). You'll also need the vehicle identification number (VIN) of the car you're buying, or at minimum the make, model, and year.
You'll need to decide on a down payment amount. Most lenders require at least 10 percent of the car's price, though 20 percent is more common and results in a lower interest rate. The larger your down payment, the less you borrow and the less interest you pay overall.
Be prepared to provide your Social Security number, current address, employment history for the past two years, and information about any existing debts. Lenders pull your credit report directly, so you don't need to provide that yourself.
The difference between loan terms and what each costs you
Loan terms range from 24 months to 84 months, though 48 to 72 months is most common. A shorter term means higher monthly payments but less total interest paid. A longer term spreads the cost across more months, lowering your payment but increasing the total interest.
Here's the trade-off in concrete terms: a $25,000 loan at 5% interest costs $5,563 in total interest over 48 months (about $573 per month), but $7,453 in total interest over 72 months (about $459 per month). You save $114 per month, but pay $1,890 more overall. Choose the shortest term you can afford monthly, because the savings in interest compound quickly.
Another consideration: cars depreciate fastest in the first few years. If you take out a 72-month loan on a car, you may owe more than the car is worth for the first few years. This matters if you want to trade in or sell the car early. A shorter loan term keeps you from being "upside down" on the loan.
What happens after you're approved
Once approved, the lender sends the money directly to the dealership or seller. You sign the loan agreement, which spells out your monthly payment, interest rate, loan term, and what happens if you miss a payment. The lender files a lien against the car's title, meaning they have a legal claim to it until the loan is paid off.
Your first payment is typically due 30 days after the loan closes. Set up automatic payments from your bank account to avoid missing a due date — missing even one payment damages your credit score and can trigger late fees. Most lenders allow you to pay extra toward principal without penalty, which shortens the loan and saves interest.
You own and drive the car when ready, but you cannot sell it or refinance it without the lender's permission until the loan is paid off. Once you make the final payment, the lender releases the lien and sends you the title, at which point the car is fully yours.
Common mistakes to avoid when taking out a car loan
The biggest mistake is borrowing more than you need. Dealerships and lenders will offer you the maximum amount you may have access to for, but that doesn't mean you should take it. Borrow only what the car costs plus taxes and fees. Borrowing extra for repairs, maintenance, or other expenses means paying interest on money you may not need.
Another common error is skipping the pre-approval step and letting the dealership arrange financing. Dealerships mark up the lender's rate, sometimes by 1 to 3 percentage points. That markup costs you thousands over the life of the loan. Always get pre-approved first.
Don't ignore the loan agreement before signing. Read the interest rate, term, monthly payment, and penalty clauses. Some loans charge extra fees for paying off early or for missing a payment. Understand what you're signing before you commit.
Frequently Asked Questions
Can I get a car loan with bad credit?
Yes, but the interest rate will be significantly higher. Some lenders specialize in loans for people with credit scores below 600, though rates may exceed 10 percent. A larger down payment or a co-signer with better credit can improve your terms. It's worth shopping around, because rates vary widely among lenders willing to work with lower credit scores.
What's the difference between a fixed and variable interest rate?
Almost all car loans use a fixed rate, meaning your interest rate stays the same for the entire loan term. A variable rate would change over time, but car lenders don't typically offer this option. Your rate is locked in when you sign the loan agreement and doesn't change, even if interest rates in the economy rise or fall.
Can I refinance my car loan later?
Yes. If your credit score improves or interest rates drop, you can refinance by taking out a new loan to pay off the old one. This works best if you've paid down a significant portion of the original loan, because refinancing resets the clock. You'll pay new closing costs, so refinancing only makes sense if the new rate is at least 1 to 2 percentage points lower.
What happens if I can't make a payment?
Contact your lender when ready. Many lenders offer hardship programs that temporarily lower or pause your payment. Missing a payment damages your credit score and triggers late fees. If you miss multiple payments, the lender can repossess the car, which means they take it back legally. Repossession also severely damages your credit for years.
Do I need gap insurance?
Gap insurance covers the difference between what you owe on the loan and what the car is worth if it's totaled in an accident. It's most useful if you're putting down less than 20 percent, because you'll owe more than the car is worth for the first few years. Some lenders require it; others offer it as an option. Compare the cost against the risk before deciding.
