Using the formula for FV of annual annuity,
Future value of annuity (FV) = Periodic Payment (P) x [(1+r) n - 1 /r]
r = Rate per period = 7.5 %
n = Numbers of periods = 30
FV = 7,000 x [(1 + 0.075)30 – 1/0.075]
= 7,000 x [(1.075)30 – 1/0.075]
= 7,000 x [(8.754955 – 1)/0.075]
= 7,000 x (7.754955/0.075)
= 7,000 x 103.3994
= 723,795.82
This fund of $ 723,795.82 will facilitate cash flow for next 25 years. So considering this amount as PV at the time of retirement, we can calculate future cash flow as:
PV (at the time of retirement) = P x [1-(1+r)-n/r]
$ 723,795.82 = P x [1-(1+0.075)-25/0.075]
= P x [1-(1.075)-25/0.075]
= P x [(1-0.163979)/0.075]
= P x (0.836021/0.075)
= P x 11.14695
P = $ 723,795.82/11.14695 = $ 64,932.21
Elder brother can spend $ 64,932 per year after retirement.
