Quick explanation: Revenue is the money a company earns from selling goods or services before deducting expenses. Net profit is what remains after expenses, interest and taxes. EPS (earnings per share) expresses the earnings attributable to ordinary shareholders on a per-share basis. Confusing revenue vs net profit, or either of them with EPS, is one of the most common mistakes in reading company results.
Understanding the profit flow
A simplified income statement follows this path:
Different companies report additional lines, including other income, depreciation, exceptional items, share of profit from associates and joint ventures, and profit attributable to non-controlling interests. Always use the appropriate published statement and read its notes.
Revenue is often called the "top line" because it sits at the top of the income statement. Net profit, also called profit after tax (PAT), is the "bottom line".
Worked example: revenue to profit
| Particulars | Amount (₹ Cr) |
|---|---|
| Revenue | 10,000 |
| Operating expenses | (8,000) |
| Operating profit | 2,000 |
| Interest and other net expenses | (400) |
| Profit before tax | 1,600 |
| Income tax | (400) |
| Net profit | 1,200 |
Revenue of ₹10,000 crore does not mean the company earned ₹10,000 crore of profit. Here, only 12 rupees of every 100 in sales reached shareholders as profit.
Two other margins are worth knowing. Operating margin is operating profit divided by revenue: 2,000 ÷ 10,000 = 20% here. It shows how profitable the core business is before financing costs and tax. Many analysts also track EBITDA, earnings before interest, tax, depreciation and amortisation, which adds back non-cash depreciation; it is useful for comparing capital-heavy businesses, but it is not cash flow and not profit.
Worked example: EPS
Assume the ₹1,200 crore net profit is fully attributable to ordinary equity shareholders, with 120 crore weighted-average ordinary shares and no other adjustments.
If the share price is ₹250:
EPS is the bridge between a company's total profit and the value of a single share. It is the earnings figure that the P/E ratio uses.
EPS and the share count
Basic EPS normally uses the weighted-average number of ordinary shares outstanding during the reporting period, not necessarily the number outstanding on the latest market day. If a company issued new shares halfway through the year, those shares count for only half the year in the average.
Diluted EPS also accounts for potentially dilutive instruments, such as employee stock options or convertible securities, where applicable. It shows what EPS would be if those instruments turned into shares, and is usually slightly lower than basic EPS.
Because of these definitions, a simple Market Cap ÷ Profit calculation can differ slightly from Share Price ÷ reported EPS if share counts, periods or attributable-profit definitions differ.
Splits and bonus issues increase the share count without changing profit, so EPS falls proportionally. Companies restate past EPS for comparability, which is why EPS histories should always be checked on a consistent, adjusted basis.
Revenue growth versus profit growth
Consider a company whose revenue rises from ₹10,000 crore to ₹12,000 crore, while profit falls from ₹1,200 crore to ₹900 crore.
Profit Growth = (900 − 1,200) ÷ 1,200 × 100 = −25%
Sales growth alone does not ensure earnings growth. Costs, financing expenses, taxes and margins all matter. Here the net margin fell from 12% to 7.5%. Common reasons include rising raw-material costs that could not be passed on, price cuts to win volume, higher interest on new borrowings, or heavy spending on expansion that has not yet produced returns.
The reverse also happens: profit can grow faster than revenue when margins improve, for example through lower input costs or better use of existing capacity. That kind of growth is valuable but has limits, because margins cannot rise forever.
Reading these figures in quarterly results
Look for the line names. In Indian results, revenue usually appears as "revenue from operations", separate from "other income" such as interest on surplus cash. Analysing the core business usually means focusing on revenue from operations.
Watch exceptional items. One-off gains, such as selling a property, or one-off losses, such as a large write-off, can make net profit look unusually high or low in a single period.
Check standalone versus consolidated. Companies with subsidiaries report both, and the figures can differ greatly; S09 explains which to use for valuation.
Compare like with like. Compare a quarter with the same quarter last year to remove seasonal effects, and compare full years with full years.
Key takeaways
- Revenue is not profit.
- Profit margin shows how much revenue becomes profit.
- EPS converts attributable earnings into a per-share measure, using a weighted-average share count.
- Compare earnings and EPS on the same reporting basis and period.
- P/E ultimately depends on earnings, not revenue alone.

Frequently Asked Questions
What is the difference between revenue and net profit?
Revenue is total sales before expenses. Net profit is what remains after operating costs, interest and taxes, so it is usually a small fraction of revenue.
What is EPS?
Earnings per share: profit attributable to ordinary shareholders divided by the weighted-average number of ordinary shares during the period.
What is the difference between basic and diluted EPS?
Diluted EPS also counts potential shares from instruments such as stock options or convertibles, so it is usually slightly lower than basic EPS.
Can revenue grow while profit falls?
Yes. Rising costs, price cuts, higher interest or taxes can shrink margins so that profit falls even as sales grow.
What is net profit margin?
Net profit divided by revenue, expressed as a percentage. It shows how much of each rupee of sales reaches shareholders as profit.
