Loan Amortization
• A mortgage loan to be repaid over 20 years at 8% interest:

Loan Amortization Table
•In such a case the part of the payments to the mortgage company will go toward the payment of interest, with the remainder applied to debt reduction, as indicated in the following table: Table 9–6
• A generalized formula for Future Value of Annuity: FVA = A × FVIFA
Where: FVA = Future value of the Annuity FVIFA = Annuity Factor = {[(1+i)n – 1] ÷ i} A = Annuity value i = Interest rate n = Number of periods; • Assuming, A = $1,000, n = 4, and i = 10%

Relationship to The Capital Outlay Decision
• The time value of money is used to determine whether future benefits are sufficiently large to justify current outlays

Yield – Present Value of a Single Amount
• To calculate the yield on an investment producing $1,464 after 4 years having a present value of $1,000:
• The Present Value of an Annuity is the sum of the present values of single amounts payable at the end of each period
– The relationship between the Future Value and Future Value of Annuity

Determining the Yield on Investment
• Determining the unknown variable “ i “, given the following variables :
1. FV/PV : Future/Present value of money 2. N : no. of years 3. A : Annuity Value / payment per period in an
– The relationship between present value and future value
• Inverse relationship exists between the present value and future value of a single amount
– The relationship between the Present Value of a single amount and the Present Value of an Annuity
• A re-look at the variables involved in time value of money:
1. FV/PV : Future/Present value of money 2. N : no. of years 3. I : Interest or YIELD 4. A : Annuity Value / payment per period in an annuity
– Assuming n = 4, i = 6%:

Relationship of Present Value to Annuity
Annual interest is based on the beginning balance for each year as shown in the following table that shows flow of funds:
• The Future Value of an Annuity is the sum of the future values of single amounts receivable at the end of each period

Future Value – Single Amount (Cont’d)
A generalized formula for Future Value:
Where FV = Future value PV = Present value i = Interest rate n = Number of periods;
• A generalized formula for Present Value of Annuity: PVA = A × PVIFA
Where: PVA = Present value of the Annuity PVIFA = Annuity Factor = {1 – [1 ÷ (1+i)n] ÷ i} A = Annuity value i = Interest rate n = Number of periods
• Future Value of an Annuity:
– Calculated by compounding each individual payment into the future and then adding up all of these payments

Future Value – Annuity (cont’d)
– For n = 4, and i = 10%, $1,000 as below :
is 4.641. Thus, A equals

Annuity Equaling a Present Value
– Determining what size of an annuity can be equated to a given amount:
In the previous case, PV = $1,000, i = 10%, n = 4, hence;

Present Value – Annuity
• Calculated by discounting each individual payment back to the present and then adding up all of these payments
• Mathematical tools of the time value of money are used in making capital allocation decisions

Future Value – Single Amount
• Measuring value of an amount that is allowed to grow at a given interest over a period of time
• Given the first three variables, and determining the fourth variable “A” (unknown ).

Annuity Equaling a Future Value
– Assuming that at a 10% interest rate, after 4 years, an amount of $4,641 needs to accumulated:
– The formula for the present value is derived from the original formula for future value:
– The present value can be determined by solving for a mathematical solution to the formula above, thus restating the formula as:
rate • Present value based on current value of
funds to be received • Determining Yield on an Investment. • Compounding or discounting occurring on a
less than annual basis
