A sunk cost is a cost that an entity has incurred, and which it can no longer recover by any means. Sunk costs should not be considered when making the decision to continue investing in an ongoing project, since you cannot recover the cost.

irrelevant cost. A cost incurred by a company which is unaffected by management's decisions. Such costs can be either positive or negative and may even turn out to be a relevant cost in certain situations. For example, if a company bought an off-the-shelf software program but it did not work as intended and cannot be returned, the cost incurred (sunk cost) becomes irrelevant regardless of management's decision.
