Question

Yes, I need help in answering this question. My answer is 6.46%, however, the online assignment says its wrong. How do you solve this question? Here is the question: On January 1, 1980, Julie received an annuity-certain. The annuity promised to pay $200 on each September 30th through 1997 and $300 on each December 31st through 1997. If the value of the annuity on January 1, 1980 was calculated to be $5,100, what annual effective rate of interest was used? (Round your answer to two decimal places.)

Explanation / Answer

Make cash flows starting Jan 1, 1980 to 30 sep 1980 to dec 31 1980......dec31, 1997

Jan 1 1980    -5100

Sep 30 1980        200

Dec 31 1980       300

Like this there will be 37 dates with 37 cashflows.

Use XIRR in excel XIRR (all dates, all cash flows) = 0.068977 =6.90%
