Quizplus · Accepted Answer

A sunk cost is a cost that has already been incurred and cannot be recovered or changed. It is not relevant to any current or future decision because it is already "sunk" or gone. Period costs are expenses that are not related to the production of goods or services and are expensed in the period they are incurred. Opportunity costs are the benefits forgone by choosing one alternative over another. Differential costs are the difference in costs between two alternatives.
