How It Works
Enter vehicle price & down payment
Type the purchase price and any amount you plan to put down upfront. A larger down payment lowers your monthly payment and total interest.
Set your term and APR
Select a loan term from 24 to 84 months and enter the APR from your financing offer. Shorter terms cost less total interest but higher monthly payments.
Add trade-in & sales tax (optional)
Enter your trade-in vehicle's value to reduce the amount financed. Add your local sales tax rate to roll it into the loan calculation.

Frequently Asked Questions
Is my financial data stored or shared?
No. All calculations run locally in your browser. The values you enter are never sent to or stored on any server.
What is APR and how does it differ from the interest rate?
APR (Annual Percentage Rate) includes the interest rate plus any fees rolled into the loan. For a simple auto loan with no origination fees, APR and interest rate may be identical. Always use the APR figure from your financing offer for the most accurate estimate.
How is the monthly car payment calculated?
The calculator uses the standard PMT formula: M = P × r(1+r)ⁿ / ((1+r)ⁿ − 1), where P is the amount financed, r is the monthly rate (APR ÷ 12 ÷ 100), and n is the number of payments. All arithmetic runs instantly in your browser.
What is a good APR for a car loan?
As of 2024–2025, buyers with excellent credit (720+) typically qualify for 5–8% APR on new cars and somewhat higher on used cars. Always compare offers from multiple lenders, banks, and credit unions before accepting dealer financing.
How does a larger down payment affect my loan?
A larger down payment reduces the amount you need to finance, which lowers your monthly payment and the total interest paid. Putting down 10–20% of the vehicle price is generally recommended to avoid going upside down — owing more than the car is worth.
