Answer:
How much money will you need to have at the moment you retire?
How much money do you need to save every year before retirement?
Explanation:
we have to first determine the amount of money you need to finance your retirement distributions:
using the annuity due present value formula, PV = annuity payment x annuity due factor (PV, 8%, n = 40)
PV = $100,000 x 12.87858 = $1,287,858
now we must use the ordinary annuity future value formula, FV = annuity payment x annuity factor (FV, 8%, n = 40)
annuity payment = FV / annuity factor = $1,287,858 / 259.057 = $4,971.33
