Frequently Asked Questions
Everything you need to know about this tool, how it works, and privacy.
What formula does the car loan calculator use?
It subtracts the down payment and trade-in value from the vehicle price for the amount financed P, then uses the fixed-rate amortization formula: monthly payment = P × r × (1 + r)^n ÷ ((1 + r)^n − 1), where r is the monthly rate (annual rate ÷ 100 ÷ 12) and n is the number of monthly payments. With a 0% rate, the monthly payment is amount financed ÷ n.
What does this car loan estimate include and exclude?
It estimates principal and interest for a fixed rate and term on the financed amount. It does not include sales tax, title, registration, dealer fees, insurance, maintenance, add-ons, or variable-rate changes. Check your lender disclosure for the full monthly obligation.
Which inputs are accepted?
Enter a vehicle price greater than zero, an optional down payment and trade-in of zero or more that together stay below the price, an annual rate from 0% through 100%, and a term greater than zero through 10 years. Decimal values are accepted, and displayed amounts are rounded to two decimal places.
Do my values stay private, and is this financial advice?
Yes. The calculation and copy action run locally in your browser, and CodeASystem does not upload or store the values you enter. This is a general estimate, not financial advice.
