Time Value of Money

A dollar received today is worth more than a dollar received in the future.
Interest - is the return you receive for investing your money. The interest rate is the basis for a test that any proposed investment must pass.
Example:

Putting \$100 in the bank
Earn 6% interest
After 1 year \$106

\$100

\$106

Future Values and compound rate
Future Value - Amount to which an investment will grow after earning interest.
Simple Interest - Interest earned only on the original investment. Compound Interest - Interest earned on interest.
- The sooner your money can earn interest, the faster the interest can earn interest.

Future Values
Example - Simple Interest
Interest earned at a rate of 6% for five years on a principal balance of \$100.

Interest Earned Per Year = 100 x .06 = \$ 6

Future Value

The general formula for the future value of an investment over many periods can be written as:
FV = C0×(1 + r)T

Where
C0 is cash
