Chapter 09: Time Value of Money
27. Annuity due (LO4) As stated in the chapter, annuity payments are assumed to come at the
end of each payment period (termed an ordinary annuity). However, an exception occurs
when the annuity payments come at the beginning of each period (termed an annuity due).
To find the present value of an annuity due, subtract 1 from n and add 1 to the tabular
value. To find the future value of an annuity, add 1 to n and subtract 1 from the tabular
value. For example, to find the future value of a $100 payment at the beginning of each
period for five periods at 10 percent, go to Appendix C for n = 6 and i = 10 percent. Look
up the value of 7.716 and subtract 1 from it for an answer of 6.716 or $671.60 ($100 ×
6.716).
What is the future value of a 10-year annuity of $2,000 per period where payments
come at the beginning of each period? The interest rate is 8 percent.
9-27. Solution:
Appendix C
FVA = A × FVIFA
28. Annuity due (LO4) Related to the discussion in problem 27, what is the present value of
a 10-year annuity of $3,000 per period in which payments come at the beginning of each
period? The interest rate is 12 percent.
9-28. Solution:
Appendix D
PVA = A × PVIFA
29. Present value alternative (LO3) Your grandfather has offered you a choice of one of the
three following alternatives: $5,000 now; $1,000 a year for eight years; or $12,000 at the
end of eight years. Assuming you could earn 11 percent annually, which alternative should
you choose? If you could earn 12 percent annually, would you still choose the same
alternative?
9-29. Solution:
