How car loans work
A car loan is an installment loan — you borrow a fixed amount and repay it with interest in equal monthly payments over a set term. Your payment depends on the loan amount, interest rate (APR), and loan term.
The loan amount is the vehicle price minus your down payment and trade-in value, plus any applicable sales tax. A larger down payment reduces the amount financed and lowers both your monthly payment and total interest paid.
Longer loan terms (72–84 months) reduce the monthly payment but significantly increase total interest paid. Shorter terms cost more each month but save money overall. This calculator generates a full amortization schedule so you can see exactly how each payment is split between principal and interest.
lightbulb Example Car Loan Scenario
Suppose you are financing a $32,000 vehicle with a $4,000 down payment at 6.5% APR over 60 months. Your monthly payment would be about $545, and you would pay roughly $4,700 in total interest over the life of the loan.
If you extended the term to 72 months, your monthly payment would drop to about $462 — but total interest paid would rise to nearly $5,700, costing you an extra $1,000 for the lower monthly payment.
A larger down payment or shorter loan term can meaningfully reduce your total cost. Use the calculator above to test different scenarios and find the right balance for your budget.
Many people use a car loan calculator to estimate monthly payments, compare loan offers from different lenders, and understand the full cost of financing a vehicle before visiting a dealership.
Car Loan Calculator FAQs
How is a car loan payment calculated?
Your monthly payment is calculated based on the loan amount, annual interest rate (APR), and loan term in months. The standard formula accounts for compound interest so that each payment covers that month's interest charge plus a portion of the principal balance.
Does a larger down payment save money?
Yes. A larger down payment reduces the amount you finance, which lowers your monthly payment and reduces the total interest you pay over the life of the loan. It can also help you avoid being "underwater" on the loan — owing more than the car is worth.
Is a longer loan term a good idea?
Longer terms (72–84 months) lower your monthly payment, but you pay significantly more in total interest and spend more time with a loan balance that may exceed the car's depreciating value. Shorter terms are generally the better financial choice if the payment fits your budget.
What APR should I expect on a car loan?
Auto loan APRs vary based on your credit score, the loan term, whether the vehicle is new or used, and the lender. Borrowers with excellent credit may qualify for rates under 5%, while those with lower scores may see rates of 10% or higher. Shopping multiple lenders is always recommended.
Auto loan terminology
Vehicle Price
The negotiated purchase price of the vehicle before tax. This is the starting point for calculating your loan amount.
Down Payment
Cash paid upfront at purchase. A larger down payment reduces the financed amount and lowers your monthly payment and total interest paid.
Trade-In Value
The value of your current vehicle applied toward the new purchase. It acts as an additional down payment and reduces the amount you need to finance.
APR (Annual Percentage Rate)
The yearly interest rate on your loan. Auto loan APRs vary based on your credit score, loan term, lender, and whether the vehicle is new or used.
Loan Term
The number of months over which the loan is repaid. Common terms are 36, 48, 60, 72, and 84 months. Shorter terms mean higher payments but less total interest.
Amortization
The process of paying off a loan through scheduled installments. Early payments go mostly toward interest; later payments go mostly toward reducing the principal balance.
