Operating Margin Explained: What Small Business Owners Should Watch
Understand operating margin, what can move it, and why rising revenue does not guarantee stronger operating performance.
Key takeaway
Operating margin helps show how much operating profit remains from revenue after normal operating costs.
Calculate the margin
Operating margin is operating profit divided by revenue, multiplied by 100. Keep the numerator and denominator from the same reporting period.
Watch the drivers
Margin can fall even while revenue rises if labor, refunds, software, facilities, contractor cost, or acquisition spending grows faster than sales.
Investigate movements instead of chasing a benchmark
Compare your margin with your own plan and prior periods, then identify which cost or revenue driver explains the change.
