The Net Present Value (NPV) method is the classic economic method of evaluating the investment proposals. It is a DCF technique that explicitly recognizes the time value of money. It correctly postulates that cash flows arising at different time periods differ in value and are comparable only when their equivalents—present values—are found out. The following steps are involved in the calculation of NPV:
  • Cash flows of the investment project should be forecasted based on realistic assumptions.
  • Appropriate discount rate should be identified to discount the forecasted cash flows. The appropriate discount rate is the project’s opportunity cost of capital, which is equal to the required rate of return expected by investors on investments of equivalent risk.
  • Present value of cash flows should be calculated using the opportunity cost of capital as the discount rate.
  • Net present value should be found out by subtracting present value of cash outflows from present value of cash inflows. The project should be accepted if NPV is positive (i.e., NPV > 0).

Acceptance Rule
  • Accept if NPV > 0 (i.e., NPV is positive)
  • Reject if NPV < 0 (i.e., NPV is negative)
  • Project may be accepted if NPV = 0

Merits
Demerits
  • Considers all cash flows
  • Requires estimates of cash flows which is a tedious task
  • True measure of profitability
  • Requires computation of the opportunity cost of capital which poses practical difficulties
  • Recognizes the time value of money
  • Ranking of investments is not independent of the discount rates
  • Satisfies the value-additivity principle (i.e., NPV’s of two or more projects can be added)

  • Consistent with the Shareholders’ Wealth Maximization (SWM) principle.
