Sales and profit
Operating Margin
The share of revenue left as operating profit: what the main business earns before interest and taxes.
Why does it matter?
It shows how much of each sale the core business keeps after all its running costs, separately from how the company is financed and taxed.
How do I read it?
Typical margins differ a lot by industry, so compare with the company's past and with companies in the same sector. It sits between gross margin (only direct costs) and net margin (all costs, interest and taxes).
How StockLab calculates it
Operating income ÷ Revenue
Example
$15 million of operating income on $100 million of revenue is a 15% operating margin: 15 cents of every dollar of sales left after running the business.
