About this calculator

A free car-loan calculator that builds the amount financed from the vehicle price, your down payment, a trade-in, and sales tax, then amortizes it at a fixed rate to estimate the monthly payment. It also shows the sales tax, the amount financed, the total interest, and the total out-of-pocket cost across the loan. It runs entirely in your browser and is an estimate, not a financing offer or APR quote.

Questions

How is the amount financed calculated?
It is the vehicle price plus sales tax, minus your down payment and trade-in value. That balance is amortized at the rate and term you enter.
How is sales tax handled?
Sales tax is applied to the vehicle price and added to the amount financed. Trade-in tax credits vary by state and are not modeled, so a state that taxes only the price after trade-in will come out a little lower.
Is it free and private?
Yes. There is no account and nothing is uploaded — the figures you enter are calculated in your browser only.
