• Measuring value of amount allowed to grow at given interest over period of time• Assuming worth of $1,000 needs to be calculated
after 4 years at 10% interest per year1st year……$1,000 × 1.10 = $1,1002nd year.....$1,100 × 1.10 = $1,2103rd year……$1,210 × 1.10 = $1,3314th year……$1,331 × 1.10 = $1,464

Future Value – Single Amount
• In determining future value, following can be used: FV = PV × FVIF
Where FVIF = interest factor
• If $10,000 were invested for 10 years at 8%, future value would be:
FV = PV × FVIF (n = 10, i = 8%)
FV = $10,000 × 2.159 = $21,590

Future Value – Annuity
• Annuity• A series of consecutive payments or receipts
of equal amount
• Future value of an annuity• Calculated by compounding each individual
payment into the future and then adding up all of these payments

• Comparisons include• Relationship between present value and future value
• Inverse relationship exists between present value and future value of single amount
• Relationship between present value of single amount and present value of annuity
• Present value of annuity is sum of present values of single amounts payable at end of each period
• Relationship between future value and future value of annuity
• Future value of annuity is sum of future values of single amounts receivable at end of each period

• Compounding frequency• Certain contractual agreements may require
semiannual, quarterly, or monthly compounding periods
• In such cases N = No. of years × No. of compounding periods
during year I = Quoted annual interest / No. of compounding
periods during year

• Patterns of Payment• Problems may evolve around number of different
payment or receipt patterns• Not every situation involves single amount or
annuity• Contract may call for payment of different amount
each year over stated period or period of annuity

Compounding Frequency— Cases
• Case 1: Determine the future value of a $1,000 investment after 5 years at 8% annual interest compounded semiannually • Where n = 5 × 2 = 10; i = 8%/2 = 4%
FV = PV × (1 + i)n
FV = $1,000 × (1.04) 10 = $1,480.24

• Assume a contract involving payments of different amounts each year for a three-year period
• To determine the present value, each payment is discounted to the present and then totaled
(Assuming 8% discount rate)

Alternate Method to Compute Deferred Annuity
1. Determine present value factor of annuity for total time period, where n = 8, i = 8%, PVIFA = 5.747
2. Determine present value factor of annuity for total time period (8) minus deferred annuity period (5)
8 – 5 = 3; n = 3; i = 8%Value = 2.577
2. Subtract the value of step 2 from the value of step 1, and multiply by A

Alternate Method to Compute Deferred Annuity
4. $3,170 is same answer for present value of annuity as that reached by first method
5. Present value of five-year annuity is added to present value of inflows over first three years
