Defining Sunk Costs

Sunk costs are costs that are unrecoverable (i.e. nonrefundable) and represent past expenditures. These should not normally be taken into account when determining whether to continue a project or abandon it because they cannot be recovered either way. It is a common irrational instinct to count them, however. Terms related to Sunk Costs are Average Total Cost, Transaction Costs, and the Cost Curve.
