What it is
DuPont Analysis decomposes Return on Equity (ROE) into its 3 drivers — profitability, efficiency, and leverage. Instead of just checking if ROE is high, DuPont tells you why it's high — and whether that's sustainable.

"DuPont matlab ROE ko todke dekhna — kya margin achha hai, kya assets efficiently use ho rahe hain, ya sirf debt ke sahare ROE upar hai?"
The formula
ROE = Net Margin × Asset Turnover × Equity Multiplier
| Component | Formula | What it measures |
|---|---|---|
| Net Profit Margin | PAT / Revenue | Profitability — how much of each rupee of revenue becomes profit |
| Asset Turnover | Revenue / Total Assets | Efficiency — how well assets generate revenue |
| Equity Multiplier | Total Assets / Equity | Leverage — how much debt amplifies returns |
The math
$$\text{ROE} = \frac{\text{PAT}}{\text{Equity}} = \frac{\text{PAT}}{\text{Revenue}} \times \frac{\text{Revenue}}{\text{Assets}} \times \frac{\text{Assets}}{\text{Equity}}$$
Why it matters
Two companies can both have 20% ROE, but for very different reasons:
| Company | ROE | Net Margin | Asset Turnover | Equity Multiplier | Quality |
|---|---|---|---|---|---|
| TCS | 40% | 22% | 1.3× | 1.4× | High quality — margin-driven |
| Tata Steel | 20% | 8% | 0.8× | 3.1× | Risky — leverage-driven |
| D-Mart | 18% | 8% | 2.5× | 0.9× | Excellent — efficiency-driven |
TCS: High ROE from high margins (pricing power + scale). Low leverage. Sustainable.
Tata Steel: Mediocre margins + low efficiency, but 3× leverage inflates ROE. If cycle turns, ROE collapses.
D-Mart: Modest margins, but incredible asset turnover (inventory turns rapidly). Minimal leverage. Very sustainable.
How to interpret each driver
1. Net Profit Margin
| Level | Interpretation |
|---|---|
| Improving | Pricing power, cost control, operating leverage kicking in |
| Stable | Mature business maintaining competitive position |
| Declining | Competition increasing, input costs rising, or scale issues |
2. Asset Turnover
| Level | Interpretation |
|---|---|
| > 1.5× | Asset-light model (IT, FMCG) or excellent efficiency |
| 1.0–1.5× | Normal for most industries |
| < 0.5× | Capital-heavy (infra, power, real estate) — just sector nature |
| Declining | Capacity expansion not yet generating revenue (may be temporary) |
3. Equity Multiplier
| Level | Interpretation |
|---|---|
| < 1.5× | Conservative balance sheet, low leverage |
| 1.5–2.5× | Moderate leverage (normal) |
| > 3× | Heavy leverage — ROE could be inflated |
| > 5× | Banks/NBFCs (normal for financial sector) |
The DuPont quality ranking
Best to worst ROE composition:
- Margin-driven — Sustainable, sign of moat (e.g., TCS, Asian Paints)
- Efficiency-driven — Sustainable, sign of operational excellence (e.g., D-Mart, Titan)
- Margin + Efficiency combined — Exceptional (rare quality businesses)
- Leverage-driven — Dangerous. Can reverse quickly if earnings drop (cyclicals with debt)
Applying DuPont in practice
Common mistakes
Mistakes to avoid
- Comparing DuPont across sectors — Banks will always have high equity multiplier; IT will always have low asset turnover. Compare within sector
- Ignoring the trend — DuPont for one year is useless. Track all 3 components over 5 years to spot deterioration
- Celebrating leverage-driven ROE — If ROE falls from 25% to 8% when you remove leverage, it's a debt house of cards
- Not linking to ROCE — Compare ROE DuPont with ROCE. If ROE >> ROCE, the difference is entirely from leverage
