Question:
A 6-year annuity of twelve $6,185 semiannual payments will begin 11 years from now, with the first payment coming 11.5 years from now. If the discount rate is 9 percent compounded monthly, what is the value of this annuity five years from now? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) Value of the annuity $ If the discount rate is 9 percent compounded monthly, what is the value three years from now? (Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.) Value of the annuity $ If the discount rate is 9 percent compounded monthly, what is the current value of the annuity?
Answer:
Discount rate=9% (0.09) compounded monthly
Semi annual interest rate=((1+(0.09/12))^6)-1=1.045852-1=0.045852
Present Value (PV) of payment=(Payment)/((1+i)^N)
i=0.045852, N=Period of payment
Payments and PV of payments are given below:
N | A | B=A/(1.045852^N) | |
Years from now | Semi annual period | Payment | PV of payment |
11.5 | 1 | $6,185 | 5913.838669 |

TOTAL | 56124.54378 |
Value of this annuity11 years from now=$56,124.54
Number of semi annual period from year 5 to year11=6*2=12
Value of annuity five years from now=$56,124.54378/(1.045852^12)= $ 32,772.54
Number of semi annual periods from 3 years to 5 years from now=4
Value of annuity three years from now= $ 32,772.54 /(1.045852^4)= $ 27,392.34
Number of semi annual period from now to 3 years=6
Current value of the annuity= $ 27,392.34/(1.045852^6)= $ 20,931.86
