Explanation

Every time an organization selects one project, it implicitly rejects alternatives. The opportunity cost is the value of the best rejected alternative. If an organization chooses Project A (expected return $500,000) over Project B (expected return $400,000), the opportunity cost of choosing Project A is $400,000—the value they gave up.

Opportunity cost is a fundamental economic concept that helps decision-makers understand the true cost of their choices. It is not a cash expense that appears on financial statements; rather, it represents the potential benefit that could have been gained from a different allocation of resources.

On the exam, opportunity cost questions typically present two or more project options and ask you to identify the opportunity cost of selecting one. Remember: the opportunity cost is always the value of the option you did not choose—specifically the highest-value alternative forgone.

Key Points

  • The value of the best alternative not chosen
  • Not a cash expense but an economic concept
  • Critical for informed project selection decisions
  • Always equals the value of the next best alternative forgone

Exam Tip

Opportunity cost equals the value of the project NOT selected. If you choose a $1M NPV project over a $750K NPV project, the opportunity cost is $750K.
