Frequently Asked Questions
What is gross margin vs net margin?
Gross margin = (Revenue − COGS) / Revenue. It measures production efficiency. Net margin = Net Profit / Revenue. It measures overall profitability after all expenses, interest, and taxes. A company can have high gross margin but low net margin if operating costs are very high.
What is a good net profit margin by industry?
Net margins vary hugely by industry. IT services: 15-25% | FMCG: 10-18% | Pharma: 12-20% | Banking: 15-25% ROE (not margin) | Retail: 2-5% | Manufacturing: 5-12% | Infrastructure: 8-15%. Compare within the same industry for meaningful analysis.
Why do margins matter for investors?
Expanding margins indicate improving operational efficiency and pricing power — signs of a strengthening business moat. Compressing margins signal rising competition or cost pressure. Companies with consistently high margins (Nestle, HUL, TCS) often make the best long-term investments.
