1. Calculating Net Present Value, Gross
Present Value and Internal Rate of
Return

2. Net Present Value
• Net Present Value is the standard technique in investment or
project appraisal for deciding whether a project is worth doing – or
an investment is worth making
• The NPV rule is that: when discounted at the target rate of return,
the NPV of the cash flow generated by an investment is not
negative, then the project is acceptable.
• It is simply the sum of the present values of all cash flows
generated by an investment or project
• The Gross Present Value is identical to the Net Present Value except
that the initial cost is ignored.

flow and discount it

6. Internal Rate of Return

7. Internal rate of return
• Technically - the Internal Rate of Return is the
discount rate at which the Net Present Value
is zero.
• It is the most important measure of actual or
expected investment performance.
• Broadly it is the average return (both capital
or income) on cash invested expressed as a %
per period
