N I% PV PMT FV P/Y C/Y = = = = = = = 2. [5pt]A $115, 000 mortgage is amortized over 30 years at an annual interest rate of 3.2% compounded monthly. (a) What are the monthly payments? N = I% = PV = PMT = FV = P/Y = C/Y = (b) How much interest is paid in all? 1 This worksheet is the same as page 8 from corresponding Lecture Notes 1 Suppose instead that the mortgage was amortized over 15 years at the same annual interest rate. (c) What are the new monthly payments? N = I% = PV = PMT = FV = P/Y = C/Y = (d) Now how much interest is paid in all? (e) How much is saved by amortizing over 15 years rather than 30?
