Question: how to calculate how much mortgage is left?
Answer: Your annual rate is 6 percent and you have made 10 years' worth of payments, so you have 240 payments left. Therefore, PMT is 1,450, N is 240 and R is 0.06/12, or 0.005. Plug them into the formula: B = (1450/0.005) x (1 - 1(1.005^240)) B = 290,000 x 0.6979 B = 202,391 You have about $202,391 left on your mortgage.
