How Auto Loans Work
What Is an Auto Loan?
An auto loan is a type of installment loan used to purchase a vehicle. You borrow a set amount from a lender—such as a bank, credit union, or dealership—and repay it in fixed monthly payments over a predetermined period, typically 24 to 84 months. Each payment includes a portion of the principal (the original amount borrowed) plus interest charged by the lender. The interest rate you receive depends on factors like your credit score, the loan term, and whether the vehicle is new or used.
Secured vs. Unsecured Auto Loans
Most auto loans are secured, meaning the vehicle itself serves as collateral. If you stop making payments, the lender can repossess the car. Because the loan is backed by an asset, secured auto loans generally offer lower interest rates compared to unsecured personal loans. Unsecured auto loans do exist but are less common and usually carry higher rates since the lender takes on more risk without collateral. For most buyers, a secured loan is the more affordable option.
How to Calculate Your Car Payment
The Auto Loan Formula
The standard auto loan formula uses amortization to calculate your monthly payment. First, determine the loan amount: take the vehicle price, subtract your down payment and trade-in value, then add any applicable sales tax. Next, convert the annual interest rate (APR) to a monthly rate by dividing by 12. The monthly payment is then calculated as the loan amount multiplied by the monthly rate times (1 + monthly rate) raised to the number of months, divided by (1 + monthly rate) raised to the number of months minus 1. Our calculator above handles all of this math for you instantly.
Understanding APR vs. Interest Rate
APR (Annual Percentage Rate) and the base interest rate are related but not identical. The interest rate is the cost of borrowing the principal, while APR includes the interest rate plus any additional fees or charges rolled into the loan. When comparing loan offers from different lenders, APR gives you a more complete picture of the total borrowing cost. A loan with a lower interest rate but high fees could actually cost more than a loan with a slightly higher rate and no fees. Always compare APR across offers for an apples-to-apples comparison.
Tips for Getting a Better Car Loan
Check and Improve Your Credit Score
Your credit score is the single biggest factor in determining your interest rate. Before applying for a loan, check your credit report for errors and take steps to improve your score if needed. Paying down existing debt, making on-time payments, and avoiding new credit inquiries can all help. Even a small improvement in your score can save you hundreds or thousands of dollars in interest over the life of the loan.
Compare Lenders
Don't accept the first loan offer you receive. Shop around with banks, credit unions, and online lenders to find the best rate. Credit unions in particular often offer lower rates to their members. Getting pre-approved by multiple lenders gives you leverage when negotiating at the dealership and ensures you're getting a competitive deal.
Choose a Shorter Loan Term
While longer loan terms (72 or 84 months) lower your monthly payment, they significantly increase the total interest you pay. A 60-month loan at 6% APR costs far less in total interest than an 84-month loan at the same rate. Use the calculator above to compare different terms and find the right balance between an affordable monthly payment and minimizing your total cost.
Make a Larger Down Payment
A larger down payment reduces the amount you need to borrow, which lowers both your monthly payment and the total interest paid. Aim for at least 20% down on a new car or 10% on a used car. A substantial down payment also reduces the risk of being “upside down” on the loan—owing more than the vehicle is worth. Before buying, use our free VIN decoder to check the vehicle's history and make sure you're paying a fair price.
What Affects Your Interest Rate
Credit Score
Lenders use your credit score to assess how likely you are to repay the loan. Borrowers with excellent credit (720+) typically qualify for the lowest rates, often below 5% APR. Those with fair or poor credit may see rates above 10% or higher. Checking your score before you start shopping helps you set realistic expectations and identify areas for improvement.
Loan Term Length
Shorter loan terms generally come with lower interest rates because the lender's risk is reduced over a shorter repayment window. A 36-month loan will almost always have a lower APR than a 72-month loan, all else being equal. While the monthly payment on a shorter term is higher, the savings on interest can be significant.
New vs. Used Vehicles
New car loans typically carry lower interest rates than used car loans. This is because new cars have a more predictable value and lower risk of mechanical issues. Used cars depreciate faster and present more uncertainty for lenders, which is reflected in slightly higher rates. That said, used cars cost less overall, so the total amount of interest paid may still be lower even with a higher rate.
Down Payment Amount
A larger down payment signals to lenders that you're a lower-risk borrower. It reduces the loan-to-value ratio, which can help you qualify for a better rate. Lenders see a borrower who puts money down as more invested in the purchase and less likely to default. Even a small increase in your down payment can improve the terms you're offered.
Check the vehicles history before you buy
Why Vehicle History Matters
Before finalizing a car purchase, always check the vehicle history report to ensure the vehicle hasn't been in major accidents or had title issues. A clean history report gives you peace of mind that you're paying a fair price for a vehicle in the condition the seller claims. Hidden damage, odometer rollbacks, and salvage titles can drastically reduce a car's value and safety. Use our VIN decoder to start your research with a free VIN lookup before committing to any purchase.
