It adds another $250,000 at the end of the first quarter, withdraws $350,000 at the end of the second quarter, adds $145,000 at the end of the third quarter, and withdraws $450,000 of the remaining funds at the end of the year. It earns $20,000 of interest in the first quarter, $17,000 in the second quarter, $12,000 in the third quarter, and 29,000 in the fourth quarter. a. What is the annual effective rate earned on the investment portfolio b. What rate of return would have been calculated if one only looked at the ending portfolio value as compared with the beginning $1,000,000 investment?

Please show all calculations in an excel spreadsheet.

Explanation / Answer

Answer :-

a.) Interest 1000000 for 12 months (full year) = 1000000 * 12/12 = 1000000

Interest 250000 for 9 months = 250000 * 9/12 = 187500

Withdraw 350000 at the end of 2nd quarter = 350000 * 6/12 = 175000

Interest 145000 for 3 months = 145000 * 3/12 = 36250

Withdraw 450000 at the end of 4nd quarter = 450000 * 1/12 = 37500

TOTAL = 1000000 + 187500 + 175000 + 36250 + 37500

= 1011250

Interest for 1st quarter = 20000

Interest for 2nd quarter = 17000

Interest for 3rd quarter = 12000

Interest for 4th quarter = 29000

TOTAL = 78000

Annual Effective Rate = 78000 / 1011250

= 7.71 %

b.) Rate of Return = 29000 / 1000000

= 2.9 %
