Bowie, age 52, has come to you for help in planning his retirement. He works for a bank, where he earns $60,000. Bowie would like to retire at age 62. He has consistently earned 8% on his investments and inflation has averaged 3%. Assuming he is expected to live until age 95 and he has a wage replacement ratio of 80%, how much will Bowie need to have accumulated as of the day he retires to adequately provide for his retirement lifestyle?

Answer:

Bowie will require  saving for $1,101,832.05 to achieve their goal.

Explanation:

He expect to have wages 800% of what he currently owns:

60,000 x 80% = 48,000

Now, this will increase 3% per year for inflation reasons:

[tex]Principal \: (1+ r)^{time} = Amount[/tex]

Principal 48,000.00

time 10.00

rate 0.03000

[tex]48000 \: (1+ 0.03)^{10} = Amount[/tex]

Amount 64,507.99

Now, we solve for the present value of an annuity of 33 year (95 - 62) with a real rate according to Irwin method of:

[tex]\frac{1+r_n}{1+\theta } -1 = r_r[/tex]

1.08/1.03 - 1 = 0.048543

[tex]C \times \frac{1-(1+r)^{-time} }{rate} = PV\\[/tex]

C 64,507.99

time 33

rate 0.048543

[tex]64507.99 \times \frac{1-(1+0.048543)^{-33} }{0.048543} = PV\\[/tex]

PV $1,101,832.0536
