Frequently asked questions

How is a car payment calculated?

Price + sales tax − down − trade-in = amount financed, spread over the term at your APR.

Does a trade-in lower sales tax?

In most states yes — tax is on price minus trade-in. This tool applies that; a few states tax the full price.

Is it really free?

Yes. 100% free, everything runs in your browser.
