A planner is starting an education needs analysis for a client whose child enrols on a degree course in exactly nine years. Tuition costs 22,000 dollars a year in today's money, education costs are expected to rise by 5.5 per cent a year, and the education portfolio is expected to earn 7.5 per cent a year. Tuition is payable at the start of each academic year, so the planner will value the stream as an annuity due at the enrolment date using an inflation-adjusted rate. Which pair correctly states the first year's tuition payable on the enrolment date and the inflation-adjusted rate to use?
- A22,000 dollars and 1.90 per cent
- B35,620 dollars and 2.00 per cent
- C35,620 dollars and 1.90 per cent Correct
- D37,579 dollars and 2.00 per cent
Why A is wrong: The rate is right but the cost is the amount payable today, not on the enrolment date. Tuition rises for the whole nine years before the first payment, so using the current figure understates every payment in the stream.
Why B is wrong: The inflated cost is right but the rate is the simple difference between 7.5 per cent and 5.5 per cent. Subtracting the rates rather than dividing the growth factors overstates the real return slightly and understates the fund needed at enrolment.
Why C is correct: The cost is 22,000 multiplied by 1.055 to the power 9, and the rate is (1.075 divided by 1.055) minus 1. Both the inflation of the first payment and the division of the two growth rates are done as the annuity due method requires.
Why D is wrong: This inflates for ten years rather than nine, counting the enrolment year twice, and also subtracts the rates instead of dividing the growth factors. Both errors are common when the timeline is drawn with the first payment one year after enrolment.
