Frequently asked questions

Is a 72-month loan a bad idea?

It lowers the payment but adds interest and keeps you underwater longer, since cars depreciate faster than long loans amortise.

Does trade-in reduce sales tax?

In many US states yes, the trade-in value is deducted before tax. This tool taxes the full price, which is the conservative case.
