What Is DuPont Analysis?
DuPont analysis (invented by the DuPont Corporation in the 1920s) decomposes Return on Equity into three multiplicative components:
ROE = Net Profit Margin × Asset Turnover × Equity Multiplier
Each component represents a different strategic lever:
| Component | Formula | What It Measures |
|---|---|---|
| Net Profit Margin | Net Income ÷ Revenue | Pricing power and cost efficiency |
| Asset Turnover | Revenue ÷ Total Assets | Operational asset efficiency |
| Equity Multiplier | Total Assets ÷ Equity | Financial leverage |
Why DuPont Matters
Two companies with the same 20% ROE may have completely different profiles:
- Company A: 20% margin × 0.5× turnover × 2× leverage = 20% ROE
- Company B: 5% margin × 2× turnover × 2× leverage = 20% ROE
Company A (software) and Company B (retail) have the same ROE but very different risk profiles. Company A's ROE is more sustainable because it comes from margin; Company B relies on both asset efficiency and leverage.
How to Improve Each Driver
Improving Net Profit Margin
- Raise prices on high-demand products
- Cut COGS through supplier negotiation or product redesign
- Reduce fixed overhead (headcount, real estate)
- Shift revenue mix toward higher-margin products
Improving Asset Turnover
- Sell underused assets
- Reduce inventory levels (just-in-time procurement)
- Speed up the cash conversion cycle (reduce DSO)
- Increase capacity utilization before adding new assets
Managing the Equity Multiplier
- Add debt judiciously when ROA > cost of debt
- Buy back shares when stock is undervalued and cash flow is stable
- Avoid excessive leverage that increases default risk during downturns
