Operating Margin Calculator
When analyzing the financial health of a business, profitability metrics are essential. One of the most insightful among them is the operating margin. It shows how efficiently a company is managing its operations and generating profit from sales.
With our Operating Margin Calculator, you can easily determine the percentage of your revenue that remains after paying for operating expenses, but before interest and taxes.
What Is Operating Margin?
Operating margin is the ratio of a company’s operating income (also known as operating profit or EBIT) to its total revenue. It tells you how much profit a business makes on each dollar of sales before interest and taxes.
It is often used to compare the performance of companies within the same industry, and to track a business’s performance over time.
Formula
The formula for calculating Operating Margin is:
javaCopyEditOperating Margin = (Operating Income / Revenue) × 100
Where:
- Operating Income = Revenue – Operating Expenses
- Revenue = Total income from sales of goods or services
The result is expressed as a percentage.
How to Use the Operating Margin Calculator
Using the calculator is simple:
- Enter your total operating income (in dollars)
- Enter your total revenue (in dollars)
- Click “Calculate”
- The tool will display your operating margin as a percentage
This metric helps you see how much operating profit you’re earning per dollar of sales.
Example Calculation
Let’s say your company’s financials look like this:
- Operating Income = $150,000
- Revenue = $500,000
Plugging these into the formula:
javaCopyEditOperating Margin = (150,000 / 500,000) × 100 = 30%
This means that 30% of your revenue remains after covering all operational expenses.
Why Operating Margin Matters

- ✅ Efficiency Insight – Shows how well you control operating costs
- ✅ Comparative Analysis – Benchmark against industry competitors
- ✅ Financial Health – High margins = more buffer for debt, taxes, or expansion
