Simple definition
What percentage of every rupee of revenue ends up as actual profit for shareholders — the ultimate profitability metric.
🗣️
"Net Margin batata hai ki company ke har ₹100 ki sale mein se kitna paisa actually bacha shareholders ke liye. 15% matlab ₹15 bacha."
Why it matters
- Bottom-line efficiency — captures everything: COGS, operating expenses, interest, tax
- Profitability benchmark — quickly tells you if the business is truly profitable
- Component of ROE (DuPont: Net Margin × Asset Turnover × Equity Multiplier)
- Sustainability check — very thin margins leave no room for error
Formula
Net Profit Margin = (PAT / Revenue from Operations) × 100
Good range — by sector
| Sector | Strong NPM | Average | Weak |
|---|---|---|---|
| IT Services | > 22% | 15–22% | < 12% |
| FMCG | > 15% | 10–15% | < 8% |
| Banking | > 25% (on NII) | 15–25% | < 10% |
| Pharma | > 18% | 12–18% | < 8% |
| Auto OEM | > 8% | 5–8% | < 3% |
| Steel/Metals | > 10% | 5–10% | < 3% |
Margin waterfall: Where revenue leaks
| Level | What's deducted | Typical % lost |
|---|---|---|
| Revenue → Gross Profit | COGS (raw materials) | 30–60% |
| Gross Profit → EBITDA | Employee costs, other expenses | 15–30% |
| EBITDA → EBIT | Depreciation & amortisation | 3–15% |
| EBIT → PBT | Interest / finance costs | 1–5% |
| PBT → PAT | Income tax | ~25% of PBT |
Common mistakes
Mistakes to avoid
- Comparing across sectors — 5% for auto is normal; 5% for IT is terrible
- Banks: use NIM, not NPM — Bank revenue structure is completely different
- One-time items — Exceptional gains/losses severely distort NPM in a given year
- Ignoring the margin trend — A single year's margin is less meaningful than a 5-year trend
Real example: Margin comparison within FMCG
| Company | Revenue (₹ Cr) | PAT (₹ Cr) | Net Margin |
|---|---|---|---|
| HUL | 60,000 | 10,500 | 17.5% |
| ITC | 70,000 | 19,400 | 27.7% |
| Dabur | 12,000 | 1,850 | 15.4% |
| Marico | 9,800 | 1,550 | 15.8% |
ITC's exceptional margin comes from its cigarette business (high excise pass-through but very high gross margins on tobacco).
Red flags
- Net margin < 5% for non-commodity businesses — too thin for comfort
- Net margin declining while competitors' margins are stable — company-specific issue
- Net margin volatile (swings 5%+ year to year) — unpredictable business
- Net margin boosted by Other Income rather than operating performance
