Value of an annuity versus a single amount Personal Finance Problem Assume that you just won the state lottery. Your prize can be taken either in the form of $82.000 at the end of each of the next 25 years (that is, $2, 050,000 over 25 years) or as a single amount of $1, 388,000 paid immediately. If you expect to be able to earn 11% annually on your investments over the next 25 years, ignoring taxes and other considerations, which alternative should you take? Why? Would your decision in part a change if you could earn 13% rather than 11% on your investments over the next 25 years? Why? On a strictly economic basis, at approximately what earnings rate would you be indifferent between the two plans? To decide which alternative to take, you need to compare the values of these alternatives. Although the total nominal dollar amount of the annuity is much larger than the single payment, the former is not necessarily a better choice due to the different timing of cash flows. A way to make a meaningful comparison of the two alternatives is to compare their present values
