Answer
NPV is calculated by discounting future cash flows to present value using required return rate, then subtracting initial investment cost.
Net Present Value (NPV) is a fundamental capital budgeting tool that helps evaluate investment profitability by comparing present value of future cash flows to initial investment.
Calculation Steps:
- Identify all future cash flows from the investment
- Determine the appropriate discount rate (often WACC)
- Calculate present value of each cash flow: PV = CF / (1+r)^n
- Sum all present values
- Subtract initial investment: NPV = ΣPV - Initial Investment
Decision Rule:
- NPV > 0: Accept project (creates value)
- NPV < 0: Reject project (destroys value)
- NPV = 0: Indifferent (breaks even)
Key Considerations:
- Use realistic cash flow projections
- Choose appropriate discount rate reflecting project risk
- Consider terminal value for long-term projects
- Account for taxes and working capital changes
NPV is superior to payback period and accounting return methods because it considers time value of money and all cash flows. However, it requires accurate forecasting and discount rate estimation.
