FUTURE VALUE
Cash flow
worth more
today
The term future value (FV) refers to the value of a cash flow at a
specified rate of interest at the end of a stated length of time. A cash
flow that is received today is worth more than the same amount
received in the future. Cash in hand today may be invested to earn a
return over a period of time.
Example
For example, an investor receiving $100 today may have the
opportunity to invest the $100 for one year at 10% per annum (p.a.).
With a risk-free investment in an environment free from inflation,
the investor will have $110 value at the end of the one year. If the
receipt of the $100 is delayed for one year, the investor will have
only $100 at that time; the opportunity to earn the 10% will have
been lost. The principal plus the return on the investment over time
represents the future value of the investment.
Calculating Interest Payments
Simple /
compound
interest
There are two methods for calculating interest payments on debt
instruments: simple interest and compound interest. In this
section we will look at the formulas for deriving a simple interest
payment and a simple interest rate. We also will see how interest is
compounded discretely at regular intervals or continuously over a
defined period of time.
In our discussions, we show formulas and calculations so that you may
understand the process and become familiar with the terminology.
However, a financial calculator is the most efficient and accurate tool
for solving the types of problems in this course. We recommend that
you become familiar with the functions on your financial calculator.
