Time Value of Money

The dollar amount cash flows difference between the present value of an amount and its future value. The difference is also referred to as the interest.

Example:

The time value of $100 for one year at i = 10%.

Present value=$100

Future value=$100 x (1+10%)=$110

The time value of one year for this $100

=$110-$100=$10

A.Future Value of A Single Amount

FV= I x ( 1 + i)n

Where:FV = Future value of the invested amount;

i = Amount invested at the beginning of the

period;

n = the number of compounding periods.

Example: The future value of $10,000 invested on

1/1/x1, at the end of year 2 (i.e.;12/31/x2)

with i=10%.

$10,000 x (1+i)2 = $12,100

Page 4: Chapter

Time Value of Money Concepts 4

B.Present Value of A Single Amount

FV = I x (1 + i)n

I = FV / (1 + i)n

Where: I = Present value of a single amount.

Example: The present value of $12,100 to be

received two years from now with i =10%

$12,100 / (1+10%)2 = $10,000

C. Annuity The cash flows of a constant amount to be received or

paid each period.

Case 1: Future value of an ordinary annuityFVA: Annuity amount x future value annuity factorExample:The future value of paying $10,000 every year

for the following three years at i= 10%. The first $10,000 is to be paid one year from today (n=0).

C.Annuity (contd.) Case 1 (contd.)

The future value of these payments (an ordinary annuity) is:

Payment FV of $1,i=10%

Future Value(at the end of year 3) n

First Payment $10,000 x 1.12a = $12,100 2

SecondPayment

$10,000 x 1.10b= $11,000

Third Payment $10,000 x 1.00 = $10,000 0

Total 3.31 = $33,100

This annuity is similar to that of Case 1 except that the first payment was made at the beginning of year 1.

Third Payment $10,000 x (1+10%) = $11,000 1

Total 3.641 = $36,410

A short cut: $10,000x3.641=36,410

C.Annuity (contd.) Case 3:Pre. Val. of An Ordinary Annuity

PVA=annuity amount x present value annuity factor Example: The present value of paying $10,000 every year for the following three years at

i=10%. The first $10,000 is to be paid one year from today (n=0). Diagram of these payments

C.Annuity (Contd.) Case 3: (contd.) The Present value of these payments (an ordinary

annuity) is: Payment PV of $1,i=10%

Present Value(at the end of year) n

First Payment $10,000 x 0.90909a = $9,091 1

SecondPayment

$10,000 x 0.82645b= $8,264

Third Payment $10,000 x 0.75131 = $7,513 3

Total 2.48685 = $24,868

a=1/(1+10%)=0.90909b=1/(1+10%)2=0.82645

A short cut: $10,000 x 2.48685=24,868
