Question

1) Suppose you just won the state lottery, and you have a choice between receiving $2,075,000 today or a 20-year annuity of $250,000, with the first payment coming one year from today. What rate of return is built into the annuity? Disregard taxes.

Sam was injured in an accident, and the insurance company has offered him the choice of $49,000 per year for 15 years, with the first payment being made today, or a lump sum. If a fair return is 7.5%, how large must the lump sum be to leave him as well off financially as with the annuity?

You have a chance to buy an annuity that pays $28,000 at the beginning of each year for 5 years. You could earn 4.5% on your money in other investments with equal risk. What is the most you should pay for the annuity?

Explanation / Answer

(1) 9.44%

Present value of the two amounts are equal.

$2,075,000 = $250,000 x PVIFA(R%, 20 years)

PVIFA(R%, 20 years) = 8.3

From PVIFA table for year = 20, we find that 8.3 corresponds to an interest rate just below 10%. Among given choices, only 9.44% fits.

(2) $464,968.53

Required lump-sum = Present value of the annuity

= $49,000 x PVIFA(7.5%, 15 years) x 1.075 [Since this is annuity due]

= $49,000 x 8.8271 x 1.075

= $464,967.5

** The slight difference is due to rounding-off.
