Start the lessonIntroduction
Operating profit as a share of revenue
Operating margin measures operating profit relative to revenue. It gives a percentage view of how much remains from sales after operating costs are accounted for, before interest and tax. It is also commonly called operating profit margin.
The short answer
Operating margin = operating profit ÷ revenue × 100. It helps compare operating profitability, but definitions and business contexts matter.
The formula
Divide operating profit by revenue
Operating Margin = Operating Profit ÷ Revenue × 100
Operating profit is generally the profit from a company's core operations before interest and tax. The exact line item and adjustments can vary by company, accounting presentation, or data source, so check what is being used.
₹1,000 example
Calculate an illustrative operating margin
If revenue is ₹1,000 and operating profit is ₹150, the operating margin is 15%.
Illustrative operating margin
15%
₹150 operating profit ÷ ₹1,000 revenue × 100
Negative operating profit is valid and results in a negative margin. This is an illustration only, not company data or investment advice.
How to interpret it
Compare like with like
- A higher margin means more operating profit per rupee of revenue under the calculation used.
- Compare companies in similar industries because business models and operating costs differ.
- Review changes over several periods and look for the reasons behind them, such as pricing, input costs, or efficiency.
- One-off items, accounting classifications, or restructuring costs can affect reported operating profit.
- Operating margin does not include interest and tax, so it is not the same as net profit margin.
- A high or improving margin does not guarantee that a share is fairly valued or will generate returns.
