Question

Your grandparents are talking about their retirement in a year. They told you that they should have enough in their retirement funds to pull $50,000 a year for 20 years, starting one year from today. If the discount rate is 5 percent, how much should they have in their retirement account now? Round to the nearest cent. Do not include any unit (If your answer is $111.11, then type 111.11 without $ sign.)

You just welcomed a new born boy. You want him to go to Harvard and you estimated that he will need $80,000 a year for 4 years starting 18 years from today. You are wondering how much money you need to invest in today in an investment gives 4 percent annual return to pay your son’s cost of college. How much do you need now? Round to the nearest cent. Do not include any unit (If your answer is $111.11, then type 111.11 without $ sign.)

Your friend brought up an investment opportunity that will generate cash flows of $5,000, $5,300, and $6,000 next three years, respectively. If your required rate of return on this investment is 12%, how much at most are you willing to pay? Round to the nearest cent. Do not include any unit (If your answer is $111.11, then type 111.11 without $ sign.)

Explanation / Answer

1.Present value of annuity=Annuity[1-(1+interest rate)^-time period]/rate

=$50000[1-(1.05)^-20]/0.05

=$50000*12.46221034

=$623,110.52(Approx).

2.Present value=Cash flows*Present value of discounting factor(rate%,time period)

=$80000/1.04^18+$80000/1.04^19+$80000/1.04^20+$80000/1.04^21

=$80000[1/1.04^18+1/1.04^19+1/1.04^20+1/1.04^21]

=(80000*1.863491093)

=$149079.29(Approx).

3.

Present value=5000/1.12+5300/1.12^2+6000/1.12^3

which is equal to

=$12960.09(Approx).
