A headline can celebrate record sales while the company reports a loss. Both statements can be true. Revenue and profit answer different questions.
Revenue is the starting figure
Revenue is the amount a business earns from its sales during a period. An income statement then shows the costs associated with the business and its earnings or loss. The SEC's financial-statement guide explains this sequence.
Before comparing figures, write down the period and the units. A quarterly figure in millions cannot be compared directly with a full-year figure in thousands.
Follow an imaginary biscuit business
Biscuit Co. is invented. These simplified annual figures are an arithmetic exercise, not a company report or an accounting template for every industry.
| Line | Amount | Calculation |
|---|---|---|
| Revenue | $1,000,000 | Sales for the year |
| Cost of sales | $600,000 | Ingredients and production costs in this example |
| Gross profit | $400,000 | $1,000,000 − $600,000 |
| Other operating expenses | $250,000 | Expenses beyond cost of sales |
| Operating profit | $150,000 | $400,000 − $250,000 |
| Interest and tax expense | $50,000 | Combined here to keep the exercise short |
| Net income | $100,000 | $150,000 − $50,000 |
The business sold a million dollars of biscuits. It did not keep a million dollars of profit.
Which profit does the headline mean?
Gross profit subtracts cost of sales. Operating profit also accounts for operating expenses. Net income includes the remaining income-statement effects, including interest and taxes. Actual statements may have additional lines. Check the label rather than treating every use of “profit” as the same measure.
Our fictional net margin is $100,000 ÷ $1,000,000 = 10%. That means ten cents of net income for each dollar of revenue in this example. The figure alone cannot tell us whether Biscuit Co. is an attractive investment.
More sales can still mean less profit
Now imagine next year's revenue rises to $1.2 million, but total expenses rise to $1.25 million. Sales grew by 20%; the business still lost $50,000. Ask what changed in prices, volumes and costs before drawing a conclusion.
Profit and cash flow are different
Net income is an accounting result. The cash-flow statement records cash movements and separates operating, investing and financing activities. A sale can be recorded before the customer pays; buying equipment also affects cash differently from the expense recognized in one period. Profitability and available cash deserve separate checks. See the SEC's cash-flow discussion.
Where to check a real company
Use the company's filing, then read the financial statements, footnotes and management's discussion. Form 10-K includes audited annual financial statements, but SEC filing is not an endorsement of an investment. Companies can also publish adjusted, non-GAAP measures; read their reconciliation to the comparable GAAP figure. Investor.gov explains the sections of a 10-K.
A five-minute reading exercise
- Write the filing link, reporting period and units.
- Find revenue and net income. Keep their exact labels.
- Compare the same period a year earlier.
- Read management's explanation for the change.
- Check operating cash flow and note one unanswered question.
Save those notes in the free company research checklist. Next, connect the business figures with market capitalization. Neither sales growth nor one profit number establishes a buy decision.
