Can sunk cost be ignored?

A sunk cost is a cost that cannot be recovered or changed and is independent of any future costs a business might incur. Because a decision made today can only impact the future course of business, sunk costs stemming from earlier decisions should be irrelevant to the decision-making process.

Should sunk costs be included in NPV?

Sunk costs that already have been incurred should not be included in the NPV estimation because they are not part of the future incremental cash flow associated with the acceptance of the project. While the concept of sunk costs may seem obvious, some interesting questions arise in practice.
