About the Net Margin Calculator
What is the Net Margin Calculator?
Net profit margin is the share of revenue left after every expense – cost of goods, operating costs, depreciation, interest and tax. It is the truest single measure of how profitable a business is.
This calculator builds the profit ladder from revenue down to net profit and shows the gross, operating (EBIT) and net margins at each step.
How to use the Net Margin Calculator
- Revenue (₹) (sample: 1,00,00,000)
- Cost of Goods Sold (₹) (sample: 55,00,000)
- Operating Expenses – salaries, rent, marketing (₹) (sample: 25,00,000)
- Depreciation & Amortisation (₹) (sample: 3,00,000)

Formula used
Net margin = Net profit ÷ Revenue × 100
