Net Present Value (NPV) — definition
Sum of a project's projected future cash flows, each discounted to present value at a chosen rate, minus the initial capital investment.
A positive NPV indicates a project is expected to create value above the return required by the discount rate used, typically the cost of capital or hurdle rate. NPV is widely regarded as a more reliable ranking tool than IRR when comparing projects of different scale.
Why it matters to industrial buyers
NPV translates future cash flows into a single comparable figure today, allowing capital committees to rank competing projects on a consistent, value-creation basis.
Key reference points
Discount rate sensitivity
NPV results are commonly sensitive to the discount rate assumed; small changes can materially affect the outcome for long-lived projects.
Commonly confused with
Internal rate of return
NPV shows absolute value created in currency terms; IRR expresses the same cash flows as a percentage return.
How it is used in practice
A plant selects the expansion option with the higher NPV after discounting both projects' cash flows at the company's cost of capital.
Frequently asked questions
What discount rate is typically used?
Companies commonly use their weighted average cost of capital or a project-specific hurdle rate that reflects risk.
Does a positive NPV guarantee project success?
No; NPV depends on the accuracy of the underlying cash flow forecasts and remains a projection, not a guarantee.
