Your nephew, Caleb, is 25 years old and has decided to start a retirement program. Beginning in exactly one month he will contribute the amount of $1300 into a retirement account. 80% of the funds will be invested in a high-yield equity fund that is expected to earn 8% annually; 20% of the contribution will be invested in a lower- yield bond fund that is expected to return 5% annually. He will continue to make contributions for the next 40 consecutive years. When he retires, he will combine his money into an account with an annual return of 2%. Assuming he lives another 25 years, what is the maximum amount he will be able to withdrawal per month upon retirement? What if Caleb’s assumptions are incorrect. Instead of his stock fund earning 8% annually, the fund only returns 7.5% for the investment period. Using this new assumption (but keeping all other assumptions the same), what is the maximum amount he will be able to withdrawal per month upon retirement?
