What is a auto loan?
An auto loan calculator estimates the monthly cost of financing a vehicle. Subtract your down payment and trade-in value from the vehicle price, then compare loan terms and rates. Sales tax, registration, dealer fees and optional products can change the final amount financed.
Formula and calculation method
Amount financed = vehicle price − down payment − trade-in. Monthly payment uses the standard fixed-rate installment loan formula.
