How this calculator works

The calculator estimates your amount financed from the vehicle price, sales tax, down payment, and trade-in value. It then uses the standard amortized loan formula to estimate monthly payment and total interest across the loan term.

What affects your payment?

The biggest drivers are vehicle price, APR, loan term, down payment, and trade-in value. A longer term can lower the monthly payment, but it often increases the total interest paid.
