What is a good operating margin?

A good operating margin generally exceeds 15%. Across US businesses, an operating margin of 10% is considered average, while margins exceeding 20% indicate strong pricing power, operational efficiency, and low overhead. Software/SaaS businesses often achieve 25%-35% operating margins.

How is operating margin different from net margin?

Operating margin measures profitability from core business operations before deducting interest expenses and corporate income taxes (EBIT). Net margin reflects final bottom-line profitability after all expenses, including interest, non-operating items, and statutory corporate income taxes.

Operating Margin & EBIT Formula Architecture

Operating Income (EBIT)

Operating Income = Gross Profit − Operating Expenses

Operating Margin % = (Operating Income ÷ Total Revenue) × 100

Operating margin gauges how much cash a company generates from its core operations before financing and taxes.

Operating Expense Ratio (OER)

OER % = [(SG&A + R&D + Marketing) ÷ Total Revenue] × 100

OER measures fixed overhead efficiency. Lower OER indicates operating leverage where revenue scales faster than overhead.
