Normal Profit

What Is Normal Profit?

Normal profit is the minimum return a business must earn to keep its owners willing to stay in an activity. In economics, it is treated as a cost rather than a surplus. Because it is included in total costs, a firm earning only normal profit has zero economic profit, even though its accounting profit may be positive.

The idea rests on opportunity cost. Owners who put money into a company could have invested it elsewhere, and they could have used their time and skills in another job. Normal profit compensates them for those forgone alternatives. If a business earns less than this, owners would be better off redeploying their resources. If it earns more, the excess is economic profit.

How It Is Measured

Economic profit can be expressed as:

Economic profit = Total revenue - Total economic costs

Total economic costs include explicit costs, such as wages, rent and materials paid in cash, and implicit costs, such as the return owners could have earned elsewhere. When revenue exactly equals these total costs, economic profit is zero and the business is earning normal profit.

An Illustrative Example

Suppose a small bakery's revenue covers its cash expenses and also pays the owner what the same money and working time could earn in their next best alternative. The shop reports a positive accounting profit, but its economic profit is zero. The owner is earning normal profit and has little reason to leave the business or to attract rivals into it.

Why It Matters to Investors

In perfect competition, economists expect firms to earn only normal profit in the long run. Excess profits attract new competitors, which pushes prices down until the surplus disappears. For investors, this explains why a company that looks profitable on paper may not be creating value beyond what its capital could earn elsewhere. Comparing a company's return on capital with its cost of capital asks a similar question. Normal profit is a theoretical benchmark, and real markets rarely settle at it exactly.
