About the Auto Loan Calculator
An auto loan payment depends on the amount financed (vehicle price plus sales tax, minus down payment and trade-in value), the interest rate and the loan term.
Formula: Amount Financed = Price + Sales Tax − Down Payment − Trade-in · M = P × [r(1+r)n] ÷ [(1+r)n − 1]
Sales tax rules on trade-ins vary by state — some states tax only the difference between the vehicle price and trade-in value, which this calculator assumes.
