Use in Decision Making
NPV is an indicator of how much value an investment or project adds to the firm. With a particular project, if is a positive value, the project is in the status of positive cash inflow in the time of t. If is a negative value, the project is in the status of discounted cash outflow in the time of t. Appropriately risked projects with a positive NPV could be accepted. This does not necessarily mean that they should be undertaken since NPV at the cost of capital may not account for opportunity cost, i.e., comparison with other available investments. In financial theory, if there is a choice between two mutually exclusive alternatives, the one yielding the higher NPV should be selected.
| If... | It means... | Then... |
|---|---|---|
| NPV > 0 | the investment would add value to the firm | the project may be accepted |
| NPV < 0 | the investment would subtract value from the firm | the project should be rejected |
| NPV = 0 | the investment would neither gain nor lose value for the firm | We should be indifferent in the decision whether to accept or reject the project. This project adds no monetary value. Decision should be based on other criteria, e.g., strategic positioning or other factors not explicitly included in the calculation. |

Famous quotes containing the words decision and/or making:
“A good decision is based on knowledge and not on numbers.”
—Plato (c. 427–347 B.C.)
“Our civilization is characterized by the word “progress.” Progress is its form rather than making progress being one of its features. Typically it constructs. It is occupied with building an ever more complicated structure. And even clarity is sought only as a means to this end, not as an end in itself. For me on the contrary clarity, perspicuity are valuable in themselves.”
—Ludwig Wittgenstein (1889–1951)
