Operating Margin

Definition

Operating margin measures the percentage of revenue that remains after covering operating expenses, but before interest and taxes. It reflects the profitability of a company’s core business operations.

$$\text{Operating Margin}=\frac{\text{Operating Income}}{\text{Revenue}}$$

Operating income is also known as EBIT (Earnings Before Interest and Taxes).

Why It Matters

• Shows how efficiently a company manages its core operations.
• Helps compare performance across companies regardless of financing or tax strategies.
• A higher operating margin indicates strong cost control and operational strength.
• A declining margin may signal rising expenses, pricing pressure, or operational inefficiencies.

How to Interpret It

• Higher Operating Margin: Strong operational efficiency and healthy pricing power.
• Lower Operating Margin: Weaker cost control or competitive pressure.
• Industry Context: Capital‑intensive industries often have lower margins; software and service firms typically have higher ones.

Example

A company reports:

• Revenue: $5,000,000
• Operating Income: $750,000

$$\text{Operating Margin}=\frac{750,000}{5,000,000}=0.15=15\mathrm{\%}$$

An operating margin of 15% means the company keeps fifteen cents of operating profit for every dollar of revenue.
