Question

You are trying to decide how much to save for retirement. Assume you plan to save

$ 5 comma 000$5,000

per year with the first investment made one year from now. You think you can earn

7.07.0​%

per year on your investments and you plan to retire in  

2727

​years, immediately after making your last

$ 5 comma 000$5,000

investment.

a. How much will you have in your retirement account on the day you​ retire?

b.​ If, instead of investing

$ 5 comma 000$5,000

per​ year, you wanted to make one​ lump-sum investment today for your retirement that will result in the same retirement​ saving, how much would that lump sum need to​ be?

c. If you hope to live for

2424

years in​ retirement, how much can you withdraw every year in retirement​ (starting one year after​ retirement) so that you will just exhaust your savings with the

2424th

withdrawal​ (assume your savings will continue to earn

7.07.0​%

in​ retirement)?

d.​ If, instead, you decide to withdraw

$ 74 comma 000$74,000

per year in retirement​ (again with the first withdrawal one year after​ retiring), how many years will it take until you exhaust your​ savings? (Use​ trial-and-error, a financial​ calculator: solve for​ "N", or​ Excel: function​ NPER)

e. Assuming the most you can afford to save is

$ 1 comma 000$1,000

per​ year, but you want to retire with

$ 1 comma 000 comma 000$1,000,000

in your investment​ account, how high of a return do you need to earn on your​ investments? (Use​ trial-and-error, a financial​ calculator: solve for the interest​ rate, or​ Excel: function​ RATE)
