What it means
Operating margin (or operating profit margin) is the ratio of operating income to revenue, expressed as a percentage. It measures how much profit a company makes on each dollar of sales after paying for variable costs of production and operating expenses. It is a measure of core business profitability and is used to compare companies within the same industry. A high operating margin indicates efficient management and strong pricing power. Understanding operating margin is important for evaluating a company’s profitability from its core operations.

Frequently Asked Questions
Operating Margin (%) = (Operating Income / Revenue) × 100. It measures the percentage of revenue remaining after paying for both the cost of goods sold and operating expenses (SG&A, R&D, etc.). It reflects the core profitability of the business before interest and taxes.
It varies by industry. High‑margin industries (software, pharmaceuticals) may have operating margins of 20‑40%, while retail may be 5‑10%. A consistent operating margin above the industry average is desirable.
Operating margin excludes interest and taxes, so it focuses on operating efficiency. Net margin includes all expenses and is the bottom‑line profitability.
- Cost reduction initiatives.
- Pricing power.
- Efficiencies in operations.
- Economies of scale.
A high operating margin provides a cushion against revenue declines. Companies with low operating margins are more vulnerable to economic downturns.
- It can be affected by non‑recurring items (e.g., restructuring charges).
- It does not consider capital structure.
- Comparisons across industries may be misleading.
Operating income = Revenue − COGS − Operating Expenses (SG&A, R&D, depreciation, amortization). It is also called EBIT (Earnings Before Interest and Taxes).
EBITDA margin excludes depreciation and amortization, providing a measure of cash operating performance. Operating margin includes depreciation.
A higher operating margin often results in a higher valuation (e.g., higher EBITDA multiples) because it indicates strong operational efficiency and potential for growth.
- Comparing margins across companies with different cost structures.
- Not adjusting for one‑time items.
- Ignoring that a very high margin may be unsustainable.
