Amount Financed = Vehicle Price − Down Payment − Trade-In Value + Sales Tax + Fees
Monthly Interest Rate = APR ÷ 12 ÷ 100
Monthly Payment = P × [r ÷ (1 − (1 + r)−n)]
P is financed principal, r is monthly interest rate, and n is total monthly payments.
Interest Each Month = Current Balance × Monthly Interest Rate
Principal Paid = Scheduled Payment − Interest + Extra Payments
New Balance = Previous Balance − Principal Paid
Interest Saved = Total Interest Without Extra − Total Interest With Extra
