Question

20. Problem 5.39 (Required Annuity Payments) eBook Your father is 50 years old and will retire in 10 years. He expects to live for 25 years after he retires, until he is 85. He wants a fixed retirement income that has the same purchasing power at the time he retires as $45,000 has today. (The real value of his retirement income will decline annually after he retires.) His retirement income will begin the day he retires, 10 years from today, at which time he will receive 24 additional annual payments. Annual inflation is expected to be 5%. He currently has $185,000 saved, and he expects to earn 9% annually on his savings. How much must he save during each of the next 10 years (end-of-year deposits) to meet his retirement goal? Do not round intermediate calculations. Round your answer to the nearest cent.

Answer 1

Future value Px[(1+r)^n-(1+g)^n] =(r-g) Here, 12% 1 1 Interest rate per annum 2 Number of years 3 Number of compoundings per per annum 4 = 1:3 Interest rate per period (r) 5 = 2x3 Number of periods (n) Growth rate (8) First payment (P) 12% 31 20% 7,000 Future value $ 28,268.80 7000/((1+12%)^3-(1+20%)^3)=(12%-20%)
