In this problem, we have to calculate the number of years it takes to fully exhaust the fund if Jimmy withdraws 30,000 per year
This can be calculated using NPER function in excel as in =NPER(rate,pmt,pv) where
RATE = annual interest rate = 3% = 0.03
PMT = annual withdrawal amount = 30000
PV = Present value of accumulated savings = 255906
Number of years =NPER(0.03,-30000,255906) = 9.9999 years = 10 years
(Note the PMT is input with a negative sign since it is a withdrawal and is a cash outflow)
Number of years it takes to completely exhaust the fund = 10 years
