Automotive financing calculator. Computes monthly car payments, factoring in cash down payments, vehicle trade-in values, state sales taxes, dealer documentation fees, and total interest.
Runs entirely in your browser
Financing a car involves more than the sticker price and interest rate. This calculator computes the monthly payment while accounting for the real-world factors: a cash down payment, the value of a vehicle you trade in, state sales tax, and dealer documentation fees — then shows the total interest over the term.
Those extras materially change the number. A trade-in reduces the amount financed, sales tax and dealer fees increase it, and all of them shift the monthly payment from the naive “price ÷ months” estimate. Modelling them gives a figure close to what you will actually sign for, which is what you want before walking into a dealership.
It runs in your browser, so your figures stay private. Use it to budget for a purchase, compare financing terms, or check a dealer’s quoted payment against an independent calculation.
