Revenue tells you how much a company sold. Margins tell you how much of that it actually got to keep — and at which stage the money leaks out. Three margins, read together, describe how good a business really is.
Each margin takes revenue and subtracts a bit more of the cost stack. Reading them in order shows you exactly where a company makes — or loses — its money.
Gross margin — pricing power
Gross margin is revenue minus the direct cost of producing the goods or services (COGS), as a percentage of revenue. It answers: after paying to make the thing, how much is left? A high, stable gross margin usually signals pricing power or a genuine cost advantage — the market lets the company charge well above what it costs to produce. Software has famously high gross margins; a grocer's is thin by nature.
Operating margin — how well it's run
Operating margin goes a step further, subtracting the costs of actually running the business: overhead, R&D, sales and marketing. It answers: is the core operation profitable before financing and tax? A company can have a fat gross margin but a thin operating margin if it burns everything on marketing to grow. This is the number that shows operational discipline.
Gross margin is about the product. Operating margin is about the company. Net margin is about everything else too.
Net margin — the bottom line
Net margin is what's left after everything — including interest on debt and taxes — as a percentage of revenue. It's the true "cents of profit per dollar of sales." Because it includes financing and one-off items, net margin can be noisier than the other two; a single tax event or asset sale can swing it. Useful, but read alongside the cleaner operating figure.
What a falling margin warns
The direction often matters more than the level. A slipping gross margin can mean rising input costs or lost pricing power. A shrinking operating margin while gross holds steady points to bloating costs. Compare each margin to the company's own past and to its peers — a "low" margin in a naturally thin-margin industry can still be best-in-class.
The gap tells the story: a 46% gross margin shows real pricing power, and holding 31.5% at the operating line means costs are tightly run, not spent chasing growth. A quarter of every dollar of sales survives all the way to net profit — a hallmark of a durable, high-quality business.
Educational commentary — not adviceThe three percentages are computed from reported financials; the read only interprets the shape they make. (Example reading — a point-in-time snapshot, not current data.)
Takeaways
- Gross margin = pricing power / cost advantage on the product itself.
- Operating margin = how efficiently the whole business is run, before financing and tax.
- Net margin = cents of profit per dollar of sales, after everything (but noisier).
- Watch the trend and compare to peers — direction and context beat the raw level.
