What is Net Profit Margin? How to Find High Margin Businesses
Net profit margin shows how many paise actually reach shareholders from every rupee of sales.
Net profit margin is the percentage of revenue that remains as net profit after all expenses, including operating costs, interest, depreciation, and taxes, are deducted. It is the ultimate profitability metric because it shows what percentage of every rupee earned actually belongs to shareholders.
If a company earns Rs.1,000 crore in revenue and its net profit is Rs.150 crore, the net profit margin is 15%. Out of every Rs.100 in sales, Rs.15 reaches the bottom line. The remaining Rs.85 went to raw materials, employees, rent, interest, depreciation, and taxes. A higher net margin means the company is more efficient at converting sales into profit.
Net Profit Margin = (Net Profit / Revenue) x 100
If TCS has Revenue Rs.2,40,000 Cr and Net Profit Rs.42,000 Cr: NPM = (42,000 / 2,40,000) x 100 = 17.5%
What is a good net profit margin?
It varies by industry. IT services companies like TCS and Infosys have margins of 15 to 22%. FMCG companies like HUL operate at 15 to 18%. Banking margins are measured differently because their revenue structure is unique. Commodity companies like steel and cement have 5 to 12% margins that fluctuate with commodity cycles. Always compare within the same sector.
What causes net profit margin to change?
Rising input costs without price increases reduce margins. Higher interest payments on increased debt cut into margins. Tax rate changes affect the bottom line. One-time write-offs or exceptional gains can distort margins temporarily. A company improving margins consistently over 3 to 5 years is demonstrating genuine operational improvement.

Frequently Asked Questions
Is a company with 5% net margin bad?
Not necessarily. Some industries like retail (DMart) and automobiles naturally operate on thin margins but compensate with high volumes. A 5% margin on Rs.50,000 crore revenue is Rs.2,500 crore profit. Margin should be judged within sector context, not in absolute terms.
Can net profit margin be negative?
Yes. When a company reports a net loss, the margin is negative. Loss-making startups and companies in turnaround situations have negative margins. Zomato had negative net margins for years before turning profitable. Negative margins are acceptable temporarily if the company has a clear path to profitability.
How is net profit margin different from operating profit margin?
Operating margin measures profitability from core operations before interest and tax. Net margin is after everything. A company can have a healthy 20% operating margin but a 5% net margin because of heavy debt interest. Comparing both reveals how much interest and tax burden affects the bottom line.
Which is more important: revenue growth or margin improvement?
Both matter, but sustainable margin improvement on growing revenue is the ideal combination. Revenue growth without margins is a scaling problem. Margins without revenue growth indicate a maturing business. The best investments typically show both revenue growth and stable or improving margins simultaneously.
How do I screen for high-margin companies?
Filter for net margin above 12% consistently over 5 years. Combine with revenue growth above 10% and ROE above 15%. This identifies businesses with pricing power and operational efficiency. StockkAsk at stockk.trade/stockkask can run these screens automatically.
