Operating margin measures how efficiently a company turns revenue into operating profit. It is calculated in two steps: first, Gross Profit = Revenue - COGS, which shows the profit after direct production costs. Then, Operating Income = Gross Profit - Operating Expenses, which deducts indirect costs like rent, salaries, marketing, and R&D. The operating margin percentage is Operating Income / Revenue x 100.
Gross margin reveals the profitability of the core product or service. A high gross margin means the company can charge significantly more than its direct production costs. Software companies often have gross margins above 70%, while grocery stores operate at 25-30%. Operating margin then shows how efficiently the company manages its overhead. A company with high gross margins but low operating margins may have bloated administrative or marketing costs.
Trending margins over time is more informative than any single snapshot. Improving margins suggest the business is gaining scale efficiencies, pricing power, or cost discipline. Declining margins may signal increasing competition, rising costs, or inefficient spending. Compare margins against industry peers to understand relative performance.
