How this instrument works
Accounting profit is what is left of revenue after subtracting every cost a business actually wrote a check for — wages, rent, materials, utilities, insurance — over a given period. It is the number a bookkeeper closes the books to, the figure that eventually becomes the bottom line on an income statement, and the base a sole proprietor reports on a tax return. Nothing here is estimated; every dollar subtracted has an invoice or a payroll record behind it.
The formula stays deliberately narrow: revenue minus explicit costs, full stop. It leaves out implicit costs — the salary an owner could have earned working for someone else, or the return that capital tied up in the business could have earned invested elsewhere. Economic profit subtracts those too, which is why a venture can post a healthy accounting profit while an economist would call it break-even, or worse, once forgone opportunities are priced in.
A shop owner checking whether last quarter covered its bills wants this number, not economic profit's more theoretical one — explicit costs are what actually has to be paid, on time, regardless of what else the money might have earned. The common mistake is treating accounting profit as the final word on whether running the business was worthwhile: it confirms the cash math balanced, not that the owner's time and capital earned as much as they would have doing something else.
- Enter Total revenue, $ — everything the business billed or collected in the period.
- Enter Explicit costs, $ — every cash outlay: wages, rent, materials, and other paid bills.
- Read Accounting profit — the exact difference the instrument computes between the two.
- Raise Explicit costs, $ past Total revenue, $ to see the figure turn negative, a genuine period loss.
Worked example — $500,000 in revenue, $350,000 paid out
Set Total revenue, $ to 500,000 and Explicit costs, $ to 350,000 — a small manufacturer's full-year figures, covering wages, rent, and raw materials paid out over the twelve months. Accounting profit computes as 500,000 minus 350,000, which comes to 150,000: the amount the business kept after every cash bill was settled.
That $150,000 is not the whole story of whether running the business beat the alternative. It says nothing about what the owner could have earned as a salaried manager elsewhere, or what the same capital might have returned invested in something else — those forgone amounts are implicit costs, and subtracting them from this same $150,000 is what turns accounting profit into economic profit.
Questions
Is accounting profit the same as net income?
Close, but not identical. Net income on a formal income statement typically nets out taxes, interest, and depreciation as separate line items across several stages; this instrument compresses that into one subtraction, revenue minus explicit costs, for a simplified single-period figure. For a business with no debt or tax adjustments in the period, the two numbers can match exactly.
How is accounting profit different from economic profit?
Accounting profit subtracts only explicit costs — money actually paid out. Economic profit goes further and subtracts implicit costs too: the salary an owner forwent by not working elsewhere, and the return their capital could have earned in a different investment. A business can report a solid accounting profit and a negative economic profit in the same period, once those forgone amounts are counted.
Who actually uses this figure?
Bookkeepers, small-business owners, and sole proprietors filing a Schedule C all work from this number — it is what a cash-basis income statement is built around, and it is the figure a lender asks for first when checking whether a period's revenue covered its bills. A CFO comparing divisions typically wants economic or operating profit instead, since accounting profit alone ignores the cost of capital.
Does Explicit costs, $ include depreciation?
Only if you add it in. Depreciation is a real, explicit cost recognized under standard accounting even though no check is written the day it is recorded, and a full income statement lists it on its own line. This simplified sheet treats Explicit costs, $ as a single entered figure, so fold in depreciation, amortization, or any other paid-and-recognized cost if your period should reflect them.
Can accounting profit be negative?
Yes — whenever Explicit costs, $ exceeds Total revenue, $, the sheet reports a negative Accounting profit, which is simply a loss for the period. There is no floor built into the arithmetic; a business that spent more paying its bills than it collected in revenue sees exactly that shortfall reflected as a negative number, not an error.
Why doesn't this figure include the owner's own salary?
Because a salary the owner has not actually drawn is not an explicit cost — nothing was paid out for it. If the owner does take a wage from the business, include it in Explicit costs, $ like any other payroll expense. What accounting profit still leaves out is the value of the owner's time: what they could have earned working for someone else instead, which only economic profit accounts for.
