Technical Overview: How Auto Loan Calculator Works
Auto loan calculations use the same amortization formula as standard loans: M = P × [r(1+r)^n] / [(1+r)^n-1]. The calculator factors in vehicle price, down payment, trade-in value, sales tax, and any additional fees to determine the actual amount financed. It then calculates monthly payments based on your interest rate and term length.
