Economic profit (or loss) is the difference between the revenue received from the sale of an output and the costs of all inputs, which include not only explicit costs but also implicit costs, such as opportunity costs. This measure is critical in determining the real profitability of a business, beyond just accounting profit.
Definition and Formula
Economic profit can be defined mathematically as:
Where:
- Total Revenue (TR): The total income from sales or other sources.
- Explicit Costs (EC): Direct, out-of-pocket payments for inputs such as wages, rent, and materials.
- Implicit Costs (IC): Indirect costs representing the opportunity costs of using resources owned by the business, including the cost of the owner’s own labor and capital.
Practical Examples
Example 1: Small Business Scenario
A small coffee shop earns $100,000 in revenue over a year. The explicit costs, including wages, rent, and materials, amount to $70,000. The owner forgoes a $20,000 salary from a job they could have taken instead. The economic profit is calculated as:
Example 2: Corporate Decision-Making
A corporation considers shutting down a factory. The factory generates $5 million in revenue annually, with explicit costs of $4 million. The opportunity cost of continuing operations, such as potential earnings from alternative investments, is estimated at $2 million. The economic profit (loss) would be:
Historical Context
The concept of economic profit dates back to classical economics and was further developed by economists such as Alfred Marshall and John Maynard Keynes. It provides a more comprehensive picture of profitability by considering the next best use of resources, unlike accounting profit which only accounts for explicit costs.
Applicability and Special Considerations
Applicability
- Business Strategy: Guides resource allocation and operational decisions.
- Investment Analysis: Assists in evaluating the true return on investments.
- Economic Theory: Helps in understanding market behavior and firm performance.
Special Considerations
- Accurate Opportunity Cost Estimation: Requires precise calculation of implicit costs, which can be subjective.
- Time Frame: The time horizon over which economic profit is measured can dramatically affect the results.
Related Terms
- Accounting Profit: Accounting profit refers to the total revenue minus explicit costs. It does not take into account implicit costs, making it different from economic profit.
$$ \text{Accounting Profit} = \text{Total Revenue} - \text{Explicit Costs} $$
- Normal Profit: Normal profit is the break-even point where total revenue equals total costs (both explicit and implicit). At this point, the firm earns zero economic profit.

Summary
Economic profit (or loss) provides a holistic view of a firm’s profitability by accounting for both explicit costs and implicit costs, including opportunity costs. This concept is crucial for making informed business decisions, investment analysis, and understanding firm performance in economic theory. The calculation involves subtracting both explicit and implicit costs from total revenue, offering valuable insights that go beyond mere accounting profit.
