Calculate Your Monthly Semi-Truck Payment Instantly

Formula Used

Monthly Payment = [r*PV] / [1 – (1 + r)^-n]

In this formula:
  • r is the monthly interest rate (annual rate / 12).
  • PV is the present value or principal of the loan (price – down payment).
  • n is the number of periods or payments.
  • To calculate the monthly payment, you multiply the monthly interest rate by the principal and divide that by the difference of one and the result of one plus the monthly interest rate raised to the power of the negative number of payments.
