Time Value of Money Concepts


Time value of money l.jpg
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

Time Value of Money Concepts


A future value of a single amount l.jpg

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

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%.

Time Value of Money Concepts


B present value of a single amount l.jpg

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

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%

C. Annuity

  • The cash flows of a constant amount to be received or paid each period.

  • Case 1: Future value of an ordinary annuity

  • FVA: Annuity amount x future value annuity factor

  • Example: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).

  • Diagram of these payments

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).

C.Annuity (Contd.) Case 3: (contd.)

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

  • a=1/(1+10%)=0.90909

  • b=1/(1+10%)2=0.82645

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