Opportunity Cost
Opportunity cost is the value of the best alternative forgone when a choice is made. It is a fundamental concept in economics, reflecting the idea that because resources are scarce, every decision to use resources for one purpose involves giving up the benefits that could have been obtained from the next-best alternative.[1]
Definition
Opportunity cost is not limited to monetary costs. It includes the value of any benefit that must be sacrificed in order to pursue a given course of action, whether that benefit is financial, temporal, or otherwise. For example, the opportunity cost of attending university includes not only tuition and fees but also the wages that could have been earned by working instead.[1]
Relationship to other cost concepts
| Concept | Description |
|---|---|
| Opportunity cost | The value of the best alternative forgone. |
| Accounting cost | The explicit, out-of-pocket costs recorded in financial statements. |
| Economic cost | The sum of explicit costs and implicit (opportunity) costs. |
| Sunk Cost | A cost already incurred that cannot be recovered. |
Economists distinguish opportunity cost from accounting cost because the former includes implicit costs that do not appear in accounting records but are nonetheless relevant to decision-making. A firm that ignores implicit costs of capital or the owner's time may make decisions that reduce its true economic profit.[1]
Importance
Opportunity cost is central to rational decision-making and to the analysis of comparative advantage. It also underlies the concept of marginal cost in production, where the opportunity cost of producing one more unit is the value of the resources used. Understanding opportunity cost helps individuals, firms, and governments allocate scarce resources more effectively.[1]
