To calculate present value from monthly payments, use the formula: PV = PMT × [(1 - (1 + r)^-n) / r]. Here, PV is the present value, PMT is the monthly payment amount, r is the monthly interest rate (annual interest rate divided by 12), and n is the total number of payments (months). This formula helps determine the lump sum amount you would need today to achieve a series of future monthly payments.
