Vehicle loan worksheet
Car loan price calculator
Estimate the monthly payment and total interest for a fixed-rate vehicle loan using the price and financing assumptions you enter.
Formula and assumptions
Amount financed = vehicle price + taxes and fees − down payment − trade-in. Here P is the amount financed, r is the annual interest rate ÷ 100 ÷ 12, and n is the whole-month term. At 0% interest, payment = P ÷ n. Monthly payment = P × [r(1 + r)ⁿ] ÷ [(1 + r)ⁿ − 1].
Supports dollar inputs from $0 to $100,000,000, annual interest rate from 0% to 100%, and whole-month terms from 1 to 120. Enter taxes, registration, dealer charges, and financed add-ons together; actual contracts may treat them differently. Enter the contractual interest rate, not an APR that includes fees. No negative equity or irregular payments are modeled.
