Question
Jim has received an amazing grand prize offer in the mail. The contest rules require that he pre select one of two payment options. A single lump sum payment or an annual payment for each of 25 years. I hope he wins and that you advise him correctly.
A) If we assume an annual interest rate of 8% for this analysis and that he desires the option with the greatest value today. Which option should he choose?
(Please show all work)
B) At what interest rate dose he become equally attracted to each of the 2 options?
(perform linear interpolation if necessary)
Explanation / Answer
A) Present value of Option 1 = $833,337
Present value of Option 2 = 6667+ 6667/1.08 + 6667/1.08^2 + 6667/1.08^3 ...... 6667/1.08^24 =$768,587.73
Since present value of Option 1 is higher, he should choose Option 1
B)Let interest rate be r
Present value of Option 1 = Present value of Option 2
833,337 =6667+ 6667/(1+r) + 6667/(1+r) ^2 + 6667/(1+r) ^3 ...... 6667/(1+r) ^24
By trial and error
r= 6.13%
