Operating margin is operating income divided by revenue — gross margin minus operating expenses (sales, marketing, R&D, G&A) before interest and taxes. Measures profitability from core business operations. A company with $10M revenue, $4M COGS, $3M operating expenses has $3M operating income = 30% operating margin. Software companies often achieve 30-40% operating margins at scale; capital-intensive businesses (airlines, retailers) run 5-15%. Watch the trend: companies expanding operating margins are typically gaining scale advantages; declining margins signal cost pressures, competitive intensity, or undisciplined spending. Operating margin excludes financing (interest) and tax effects for cleaner business comparison.
