A car loan is money a bank or lender gives 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 pay off the loan completely. You own and drive the vehicle, but the lender has a legal claim against it — if you stop making payments, they can repossess it. The monthly payment covers principal (the amount borrowed), interest (the lender's fee for lending), and sometimes insurance and taxes bundled into an escrow account.
The interest rate you receive depends on your credit score, the size of the loan, how long you take to repay it, and the type of vehicle. A newer car with lower mileage typically qualifies for a lower rate than an older one. The lender runs a hard credit inquiry, which temporarily lowers your credit score by a few points, and reviews your income and debt-to-income ratio to decide whether to lend and at what rate.
Key Takeaways
- Your monthly payment includes principal, interest, and sometimes property tax and insurance, depending on how the lender structures the loan.
- The interest rate you receive depends on your credit score, income, the loan amount, the loan term, and the age and condition of the vehicle.
- Lenders place a lien on the car's title until the loan is paid in full, giving them the right to repossess if you miss payments.
- A larger down payment lowers the amount you borrow, reduces your monthly payment, and often qualifies you for a better interest rate.
- Pre-approval from a lender shows you what rate and loan amount you can get before you shop for a car, which strengthens your negotiating position.
How lenders decide what rate to offer you
Your credit score is the single largest factor. Scores above 750 typically receive rates in the 3 to 5 percent range, while scores between 650 and 700 may see rates of 8 to 12 percent or higher. Lenders also look at your payment history on other debts, how much credit you currently use, and how long your credit accounts have been open.
Income and employment matter because the lender needs to know you can afford the monthly payment. Most lenders want your total monthly debt payments — car loans, credit cards, student loans, mortgages — to be no more than 40 to 50 percent of your gross monthly income. If you earn $4,000 per month and already owe $1,500 in other debts, a lender may cap your car payment at $500 to $1,000.
The vehicle itself affects your rate. Lenders view newer cars and those with lower mileage as lower risk because they hold their value better and are less likely to need expensive repairs that prevent you from paying. A 2023 sedan may may have access to for a rate one or two percentage points lower than a 2015 sedan, even if both borrowers have identical credit scores.
Down payments and how they change your loan
A down payment is money you contribute upfront toward the purchase price. If a car costs $25,000 and you put down $5,000, you borrow $20,000. The larger your down payment, the smaller your monthly payment and the less total interest you pay over the life of the loan.
Down payments also improve your approval odds and lower your interest rate. Lenders see a larger down payment as a sign you are committed and have savings, which reduces their risk. A borrower with a 20 percent down payment typically receives a rate 0.5 to 1.5 percentage points lower than one with 5 percent down, depending on credit and income.
Most lenders require a minimum down payment of 10 to 20 percent, though some credit unions and banks will lend with as little as 3 to 5 percent down if your credit is strong. If you have poor credit, lenders may require 20 to 30 percent down or decline the loan entirely.
Loan terms and what different lengths cost you
A loan term is the number of months you have to repay. Common terms are 36, 48, 60, 72, and 84 months — three to seven years. A shorter term means a higher monthly payment but less total interest paid. A longer term spreads the cost across more months, lowering your payment but increasing the total amount you pay in interest.
On a $20,000 loan at 6 percent interest, a 48-month term costs roughly $450 per month and $1,600 in total interest. The same loan over 72 months costs roughly $320 per month but $3,000 in total interest. The monthly difference is $130, but you pay an extra $1,400 in interest over the life of the loan.
Longer terms also carry more risk of being "underwater" — owing more than the car is worth. Cars depreciate fastest in the first two years. If you finance a $25,000 car over 84 months and the car is worth $15,000 after three years, you still owe $17,000. If the car is totaled in an accident, your insurance payout may not cover what you owe, leaving you responsible for the difference.
Where to get a car loan and what each source offers
Banks, credit unions, and online lenders are the three main sources. Banks typically require good to excellent credit (670 or higher) and offer competitive rates to borrowers who meet their standards. Credit unions often have lower rates than banks and are more flexible with credit scores, but you must be a member. Online lenders work with borrowers across the credit spectrum and can approve you in hours, though rates are often higher than banks or credit unions.
Dealership financing is a fourth option: the dealer arranges the loan through a lender, and you sign the paperwork at the dealership. This is convenient but often more expensive because the dealer adds a markup to the interest rate. Dealership loans are useful if your credit is poor and you cannot get approved elsewhere, but if you have decent credit, getting pre-approved by a bank or credit union first gives you more negotiating power.
Pre-approval means a lender reviews your finances and tells you the maximum loan amount and interest rate you may have access to for, without committing you to borrow. You can then shop for a car knowing your budget and rate, and you can compare the dealership's offer to your pre-approval. Pre-approval is free and takes 15 to 30 minutes online or in person.
What documents lenders require and when
Lenders ask for proof of identity (driver's license or passport), proof of income (recent pay stubs, tax returns, or bank statements), and proof of residence (utility bill or lease). Self-employed borrowers need two years of tax returns and sometimes a profit-and-loss statement. If you are explore with a co-signer, they must provide the same documents.
Once you choose a car, the lender orders a vehicle history report (Carfax or AutoCheck) and arranges an inspection if the car is used. They also confirm the vehicle identification number (VIN) matches the title. The lender then issues a loan check or electronic transfer to the seller or dealership, and you sign the promissory note and security agreement — the documents that bind you to repay and give the lender a lien on the car.
The entire process from process to funding typically takes three to five business days if you are pre-approved and the car is ready. If you are explore without pre-approval or the car needs inspection, add another week.
What happens if you miss a payment or want to pay early
Missing a single payment triggers a late fee (usually $25 to $50) and a note on your credit report. Missing two or more payments in a row gives the lender grounds to repossess the car without warning in most states. Repossession damages your credit for seven years and leaves you responsible for the difference between what the car sells for at auction and what you still owe — called a deficiency judgment.
Paying off the loan early saves you interest but may trigger a prepayment penalty, depending on the lender. Some lenders charge a flat fee or a percentage of the remaining balance; others allow unlimited early repayment with no penalty. Always ask about prepayment terms before you sign.
If you face hardship — job loss, illness, or unexpected expense — contact your lender when ready. Many offer forbearance (temporarily pausing payments) or loan modification (extending the term to lower the monthly payment). Waiting until you miss a payment makes these options less likely.
Frequently Asked Questions
Can I get a car loan with bad credit?
Yes, but at a higher interest rate and usually with a larger down payment. Credit unions and online lenders work with borrowers whose scores are 550 to 650. Expect rates of 12 to 18 percent or higher. A co-signer with better credit can lower your rate, or you can wait six months to a year while you rebuild your credit by paying bills on time and reducing credit card balances.
What is the difference between a secured and unsecured car loan?
A secured loan uses the car as collateral — the lender can repossess it if you do not pay. An unsecured loan does not use collateral but carries a higher interest rate because the lender has no way to recover their money if you default. Nearly all car loans are secured.
Should I buy a car with cash or finance it?
If you have the cash and the interest rate on a loan is low (under 5 percent), financing can make sense because you keep your savings liquid for emergencies. If rates are high (over 8 percent) or you have no emergency fund, paying cash avoids debt and interest. Consider your credit score, current savings, and the interest rate offered before deciding.
Can I refinance my car loan to a lower rate?
Yes, if your credit score has improved since you took out the original loan or if market interest rates have dropped. Refinancing replaces your current loan with a new one, usually at a lower rate. You pay a small fee to refinance, so the savings must outweigh the cost. Refinancing also resets the loan term, so make sure the new term does not extend the payoff date significantly.
What does it mean if I am underwater on my car loan?
You are underwater when you owe more than the car is worth. This happens because cars depreciate quickly while you are still paying off the loan. If your car is worth $15,000 but you owe $17,000, you are $2,000 underwater. If the car is totaled, your insurance pays the car's value, leaving you responsible for the $2,000 difference.
