What is Operating Margin?
The Operating Margin calculation tells you your operating margin from a few simple inputs. The figure you are solving for here is the operating margin, expressed in percent.
The Operating Margin formula
The core formula is:
Operating margin = Operating income (EBIT) ÷ Revenue × 100Here is what each input means:
- Operating income (EBIT) — a money amount. Example: ₹3,00,000.
- Revenue — a money amount. Example: ₹20,00,000.
How to calculate it step by step
- Write down the operating income (ebit) (for example, ₹3,00,000).
- Write down the revenue (for example, ₹20,00,000).
- Apply the formula above to get your operating margin.
- Double-check the result with the Operating Margin Calculator.
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Operating income (EBIT) | ₹3,00,000 |
| Revenue | ₹20,00,000 |
| Operating margin | 15.00% |
With operating income (ebit) of ₹3,00,000 and revenue of ₹20,00,000, the operating margin works out to 15.00%.
Example 2
With operating income (ebit) of ₹6,00,000 and revenue of ₹20,00,000, the operating margin works out to 30.00%.
| Result | Value |
|---|---|
| Operating margin | 30.00% |
Example 3
With operating income (ebit) of ₹1,50,000 and revenue of ₹20,00,000, the operating margin works out to 7.50%.

Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
