What a car loan is and how it works
A car loan is money a lender gives you to buy a vehicle. You repay that money in monthly installments over a set period — usually three to seven years — plus interest. The lender holds the title to the car until you finish paying, which means they have a legal claim to the vehicle if you stop making payments.
The lender is typically a bank, credit union, or the dealership's financing arm. Each charges different interest rates based on your credit score, income, and how much money you put down upfront. The better your credit history, the lower your interest rate will be.
Before you walk into a dealership or contact a lender, you should know your credit score, how much you can afford to put down, and what monthly payment fits your budget. This information shapes every conversation that follows.
Key Takeaways
- Your credit score is the single biggest factor determining your interest rate, so checking it before you shop saves you money.
- You can get preapproved for a loan before visiting a dealership, which tells you exactly how much you can borrow and at what rate.
- The down payment you make reduces the amount you borrow and lowers your monthly payment, so putting down more money upfront costs less over time.
- Dealership financing and bank financing are different routes with different rates — comparing both before you decide prevents overpaying.
- The loan term (how many months you pay) directly affects your monthly payment and total interest, so a longer loan means lower monthly costs but higher total cost.
Check your credit score before you shop
Your credit score determines the interest rate you will receive. A score of 750 or higher typically qualifies for the best rates. A score below 620 means you will pay significantly more, and some lenders will not work with you at all.
You can check your credit score for free through AnnualCreditReport.com, which is the official site for the three major credit bureaus. You can also check through your bank's website or a free service like Credit Karma. The score you see may vary slightly between sites because different bureaus use different data, but it will be close enough to give you a realistic picture.
If your score is lower than you expected, you have time to improve it before explore. Paying down existing debt and making on-time payments for a few months can raise your score. If you are shopping for a car soon, knowing your score now lets you decide whether to wait or accept a higher interest rate.
Get preapproved so you know your budget
Preapproval means a lender has reviewed your income and credit and agreed to lend you a specific amount at a specific interest rate. You get this in writing before you shop for a car. Preapproval is not the same as final approval — the lender will verify everything again once you pick a specific vehicle — but it gives you a firm number to work with.
Contact banks and credit unions directly to ask about preapproval. You will need to provide your Social Security number, recent pay stubs, and permission for them to check your credit. The process usually takes one to three business days. Some lenders do this entirely online; others require a phone call or in-person visit.
Getting preapproved from at least two lenders lets you compare rates. A difference of even one percentage point saves you hundreds of dollars over the life of the loan. Write down the rate, the maximum amount, and the term length for each offer so you can compare them side by side.
Decide how much to put down upfront
Your down payment is the cash you pay toward the car before financing the rest. A larger down payment means you borrow less money, which lowers your monthly payment and the total interest you pay. Most lenders want a down payment of at least 10 to 20 percent of the car's price, though some will accept less.
If you have $5,000 saved and the car costs $25,000, a $5,000 down payment (20 percent) means you borrow $20,000. If you put down only $2,500, you borrow $22,500. Over a five-year loan at 6 percent interest, that extra $2,500 borrowed costs you roughly $330 more in interest alone. The monthly payment difference is about $45.
Put down as much as you can afford without emptying your emergency savings. You need money set aside for unexpected expenses — a job loss, a medical bill, or a home repair. If putting down 20 percent leaves you with less than three months of living expenses in savings, put down less and keep your emergency fund intact.
Compare dealership financing and bank financing
You have two main routes: finance through the dealership or bring a loan from a bank or credit union to the dealership. Each has trade-offs.
Dealership financing is convenient. You pick the car, negotiate the price, and handle the loan all in one place. The dealership works with multiple lenders behind the scenes and presents you with loan offers. The downside is that dealership rates are often higher than what you could get directly from a bank, because the dealership marks up the rate slightly. Dealerships also push add-ons like extended warranties and gap insurance, which increase your total cost.
Bank or credit union financing means you arrive at the dealership with a check or a commitment letter from your lender. You negotiate the car price separately from the financing. This route usually offers lower interest rates, especially if you have good credit or are a member of a credit union. The trade-off is that you handle two separate processes — getting the loan approved and then buying the car — which takes more time.
The best approach is to get preapproved from a bank or credit union, then tell the dealership you have outside financing. Ask the dealership to match or beat that rate. Many will, because they want your business. If they do not, you walk in with your bank's loan ready to go.
Understand loan terms and monthly payments
The loan term is how many months you have to repay the loan. Common terms are 36, 48, 60, and 72 months. A shorter term means higher monthly payments but lower total interest. A longer term means lower monthly payments but higher total interest.
Here is a concrete example: a $20,000 loan at 6 percent interest costs roughly $366 per month over 60 months (five years) and $1,960 in total interest. The same loan over 72 months (six years) costs roughly $333 per month but $3,976 in total interest. You save $33 per month but pay an extra $2,016 in interest overall.
Choose the shortest term you can afford. If a 60-month payment strains your budget, a 72-month loan might be necessary — but understand that you are paying significantly more for the convenience of a lower monthly payment. Never stretch the term just to lower the payment if you can avoid it.
Review the loan agreement before signing
Once you have chosen a lender and a car, you will receive a loan agreement. This document lists the loan amount, interest rate, monthly payment, term length, and any fees. Read it carefully before signing.
Look for these specific items: the annual percentage rate (APR), which includes both interest and fees; the total amount you will pay over the life of the loan; the monthly payment amount; the due date each month; and any prepayment penalties (some loans charge a fee if you pay off the loan early). If anything does not match what you were quoted, ask the lender to explain the difference before you sign.
Do not sign if you do not understand something. Lenders are required to explain the terms clearly. If they will not, that is a red flag. Take the agreement home, read it again, and call the lender with questions. Signing a loan you do not fully understand is how people end up paying more than they expected.
What happens after you sign
Once you sign the loan agreement, the lender sends the money to the dealership or directly to you, depending on the arrangement. The dealership transfers the title to you, and you drive the car home. The lender's name appears on the title as the lienholder — the party with a legal claim to the car until the loan is paid off.
Your first payment is usually due 30 days after you sign. Set up automatic payments from your bank account if possible, because missing a payment damages your credit score and can trigger late fees. Most lenders allow you to pay online, by phone, or through automatic withdrawal.
Keep all loan documents in a safe place. You will need them if you sell the car, refinance the loan, or have a dispute with the lender. Once you pay off the loan completely, the lender will release the lien and send you the title free and clear.
Frequently Asked Questions
What credit score do I need to get a car loan?
Most lenders work with scores as low as 580 to 620, but rates are much higher at that level. Scores of 650 to 700 may have access to for moderate rates, and 750 and above get the best rates. If your score is below 620, some lenders will decline you, or you may need a co-signer with better credit.
Can I get a car loan with no credit history?
Yes, but it is harder. Lenders have no record of whether you pay bills on time, so they see you as higher risk. You may need a co-signer, a larger down payment, or a shorter loan term. Credit unions are often more flexible with first-time borrowers than banks are.
What is gap insurance and do I need it?
Gap insurance covers the difference between what you owe on the loan and what the car is worth if it is totaled in an accident. If you owe $18,000 and the car is worth $15,000, gap insurance pays the $3,000 gap. It is most useful if you put down less than 20 percent, because you are underwater on the loan from the start.
Can I pay off my car loan early without a penalty?
Most car loans allow early payoff without penalty, but some charge a prepayment fee. Check your loan agreement or ask the lender before you sign. Paying off early saves you interest, so if there is no penalty, it is usually worth doing if you have the money.
What if I cannot make a payment?
Contact your lender when ready — do not wait until the payment is late. Many lenders offer temporary payment reductions or deferrals if you explain your situation. Missing a payment damages your credit and can lead to repossession, so communicating early gives you options.
