Operating Margin

accounting
Definition
The percentage of revenue remaining after subtracting all operating expenses, measuring core business profitability.

Explanation

Operating margin = Operating Income / Revenue. It excludes interest, taxes, and non-recurring items to focus on how efficiently the company runs its core operations. High operating margins indicate pricing power and cost discipline. Software companies typically achieve 25-40% operating margins at scale. Retailers operate at 3-8%. A declining operating margin trend, even with growing revenue, signals competitive pressure or operational inefficiency. The operating margin expansion trajectory is one of the most predictive factors for future stock performance.

Formula

Operating Margin = Operating Income / Revenue × 100%
