Accounting profit is profit measured under accounting rules after subtracting explicit recorded costs from revenue. It is the profit figure that appears in financial statements, but it is not the same as the economist’s broader concept of profit.
The Core Formula
In simple form:
\[ \pi_{acct} = TR - EC \]
where TR is total revenue and EC is explicit cost, such as wages, rent, materials, interest expense, and depreciation recognized under accounting rules.
That makes accounting profit a reporting measure built around recorded transactions and standardized recognition rules.
Accounting Profit Vs. Economic Profit
Economists usually compare accounting profit with economic profit:
\[ \pi_{econ} = TR - EC - IC \]
where IC is implicit cost, or opportunity cost. This includes things like the return the owner’s capital could have earned elsewhere or the salary the owner gave up to run the business.
A firm can therefore show positive accounting profit but zero or negative economic profit if its resources would earn more in another use.
Why The Distinction Matters
Accounting profit is useful for:
- financial reporting,
- tax measurement,
- lender monitoring,
- comparing firms under common standards.
Economic profit is more useful when asking whether resources should stay in the current business. That is why the distinction matters for entry, exit, competition, and long-run market adjustment.
Limits Of Accounting Profit
Accounting profit depends on rules about revenue recognition, depreciation, provisions, and asset valuation. It is not pure cash flow, and it does not capture every relevant opportunity cost. So it is an important number, but not the whole story.
