What it means
The income statement works downwards in layers. Revenue less the direct cost of what was sold gives gross profit; less operating expenses such as salaries, rent and marketing gives operating profit; less interest and tax gives net profit.
Each layer answers a different question, and net profit answers the final one: after paying suppliers, staff, landlords, lenders and the tax authority, did the business make money. That makes it the figure lenders, investors and business owners look at first.
In practice net profit is read as a percentage of revenue, called net profit margin, because the absolute number means little without scale. A $200,000 net profit is excellent on $2,000,000 of revenue and worrying on $40,000,000.
It is important to remember that net profit is an accounting measure, not a bank balance. It includes non-cash charges such as depreciation and excludes cash movements such as loan repayments, so a profitable business can still run out of money.
Terminology varies more than people expect. Net profit, net income, net earnings and profit after tax all mean the same thing, while "profit" on its own in a conversation might mean gross, operating or net, so it is always worth asking which layer someone is referring to.
Owner pay is the other frequent source of confusion. In a limited company a director's salary is an expense that reduces net profit, whereas in a sole trader's accounts drawings are not an expense at all, so two businesses of identical size can report very different bottom lines.
In practice
Real-world examples.
Example
A bakery chain grows revenue 20% but net profit falls, because a new lease and two extra managers pushed operating expenses up faster than sales. The owner uses the net profit margin trend rather than the revenue chart to decide against opening a fourth site this year.
Example
A software reseller shows a healthy 9% net profit margin, and the bank uses that record of profitability to approve a working capital facility. The finance director points out that most of the profit is currently sitting in receivables, not cash.
Example
A logistics firm reports net profit of $1,150,000 after a one-off gain of $400,000 from selling a depot. Analysts strip out the gain to see that underlying net profit was $750,000, which is the figure they use to forecast next year. The chief executive's bonus, tied to reported net profit, becomes an awkward item at the remuneration meeting.
Think of it
“Net profit is what's left after everything-the bottom line.
Formula
Calculation
Net Profit = Revenue - Cost of Goods Sold - Operating Expenses - Interest - Tax. Net Profit Margin = Net Profit / Revenue.
A specialist furniture manufacturer reports annual revenue of $2,400,000. Cost of goods sold, covering timber, fittings and factory wages, is $1,320,000.
Gross profit = $2,400,000 - $1,320,000 = $1,080,000.
Operating expenses of $760,000 cover sales salaries, showroom rent, marketing, insurance and administration.
Operating profit = $1,080,000 - $760,000 = $320,000.
Interest on the equipment loan is $40,000, giving profit before tax of $320,000 - $40,000 = $280,000.
Tax at 30% is $84,000, so net profit = $280,000 - $84,000 = $196,000.
Net profit margin = $196,000 / $2,400,000 = 8.2%.Case study
Seen in the real world.
This illustrative case follows Marlowe and Finch Interiors, a fictional commercial fit-out contractor. Revenue had grown from $4,000,000 to $6,500,000 in two years, and the founders assumed profit had grown with it.
The year-end accounts showed net profit of $130,000, down from $290,000, giving a margin of just 2% against 7.3% two years earlier. Working back up the income statement, gross margin had held steady, but operating expenses had grown by about $560,000 as the firm added project managers, a larger office and a new vehicle fleet, and interest on the fleet finance added another $70,000.
The founders set a simple internal rule: no new overhead commitment without a matching gross profit target attached to it. They also moved the fleet to a contract that reduced annual interest and depreciation, and the following year net profit recovered to $410,000 on flat revenue.
Watch out
Common mistakes.
- Confusing net profit with cash, then being surprised when a profitable month leaves the bank account lower than it started.
- Comparing net profit margins across very different industries, when a supermarket at 2% and a software firm at 25% can both be performing well.
- Quoting a profit figure without saying which one it is, so gross profit gets compared with someone else's net profit in the same meeting.
Questions
People also ask.
Is net profit the same as net income?
Yes, along with net earnings and profit after tax; the different names are regional and stylistic rather than technical.
Can a business have positive net profit and still fail?
Yes, if cash is locked up in stock and receivables or swallowed by loan repayments, which is why cash flow is monitored alongside profit.
Should one-off items be included?
They are included in reported net profit, but analysts usually also calculate an underlying figure excluding them to see the recurring performance.
