What Is Operating Margin
Operating margin is a profitability ratio that shows how much of a company’s revenue is left after paying operating expenses.
The formula is:
Operating Margin = (Operating Income / Revenue) × 100
Operating income is also known as operating profit or earnings before interest and taxes.
This metric focuses only on core business operations and excludes non-operating factors such as interest payments and taxes.
Operating Margin Formula Explained
There are two main ways to calculate operating margin:
- Using operating income
Operating Margin = (Operating Income / Revenue) × 100
- Using revenue and operating expenses
Operating Margin = ((Revenue – Operating Expenses) / Revenue) × 100
Operating expenses include:
Cost of goods sold
Salaries and wages
Rent and utilities
Marketing and administrative costs
This calculation helps determine how efficiently a business converts revenue into profit.

Example of Operating Margin Calculation
Let’s understand with a real example.
Suppose a company has:
Revenue = 100,000
Operating Expenses = 70,000
Operating Income = 100,000 – 70,000 = 30,000
Operating Margin = (30,000 / 100,000) × 100 = 30%
This means the company keeps 30 percent of its revenue as operating profit.
Why Operating Margin Is Important
Operating margin is a key indicator of business efficiency and profitability.

Operating Margin vs Profit Margin

Operating Margin

What Is a Good Operating Margin

Real-Life Business Example
A company sells products online.
Revenue = 200,000
Operating Expenses = 150,000
Operating Income = 50,000
Operating Margin = (50,000 / 200,000) × 100 = 25%
This means the company retains 25 percent of revenue as operating profit.
If they reduce expenses by 10,000:
New Operating Income = 60,000
New Operating Margin = 30%
This shows how cost control directly improves profitability.
