To calculate fully amortizing payments, you can use the formula: P = [rPV] / [1 - (1 + r)^-n]. Here, P = payment, r = monthly interest rate (annual interest rate divided by 12), PV = present value (loan amount), and n = total number of payments or periods. It calculates the amount due each period so that the loan is paid off in full with interest by the end of its term. This formula ensures each payment covers the interest expenses and reduces the principal balance to zero.
