If you invest $17,500 today, how much will you have in each of the following instances? Use Appendix A as an approximate answer, but calculate your final answer using the formula and financial calculator methods.
a. In 7 years at 8 percent? (Do not round
intermediate calculations. Round your final answer to 2 decimal
places.)
b. In 18 years at 7 percent? (Do not
round intermediate calculations. Round your final answer to 2
decimal places.)
c. In 25 years at 6 percent? (Do not
round intermediate calculations. Round your final answer to 2
decimal places.)
d. In 20 years at 6 percent (compounded
semiannually)? (Do not round intermediate calculations.
Round your final answer to 2 decimal places.)
How much would you have to invest today to receive the following? Use Appendix B or Appendix D for an approximate answer, but calculate your final answer using the formula and financial calculator methods.
e. $14,600 in 7 years at 13 percent. (Do
not round intermediate calculations. Round your final answer to 2
decimal places.)
f. $18,800 in 18 years at 11 percent.
(Do not round intermediate calculations. Round your final
answer to 2 decimal places.)
g. $7,600 each year for 16 years at 14 percent.
(Do not round intermediate calculations. Round your final
answer to 2 decimal places.)
h. $51,000 each year for 50 years at 8 percent.
(Do not round intermediate calculations. Round your final
answer to 2 decimal places.)
For parts a to d we need to calculate future value and for parts e to h we need to calculate the present value.
Future value (FV) = Amount x (1 + r)n
Present value (PV) = Amount / (1 + r)n
where, r = interest rate, n = no. of years
a) FV = $17500 x (1 + 0.08)7 = $29,991.92
b) FV = $17500 x (1 + 0.07)18 = $59,148.81
c) FV = $17500 x (1 + 0.06)25 = $75,107.74
d) Since it is compounded semi-annually, we require semi-annual interest rate and time periods -
No. of semi-annual periods (n) = 20 x 2 = 40
semi-annual Interest rate (r) = 6% / 2 = 3%
FV = $17500 x (1 + 0.03)40 = $57,085.66
e) PV = $14600 / (1 + 0.13)7 = $6,205.89
f) PV = $18800 / (1 + 0.11)18 = $2,873.06
g) $7600 is to be received each year. This is a form of annuity. Present value of an annuity is computed as -
h) Same as g.
