DuPont Analysis
Quick Definition
A framework that decomposes return on equity (ROE) into three components: profit margin, asset turnover, and financial leverage.
Key Takeaways
- ROE = Net Profit Margin × Asset Turnover × Equity Multiplier
- Reveals whether ROE comes from profitability, efficiency, or leverage
- ROE from high margins is generally more sustainable than from leverage
- Developed by DuPont Corporation in the 1920s, still widely used
- Extended 5-factor model adds tax burden and interest burden components
What Is DuPont Analysis?
DuPont analysis (named after the DuPont Corporation which popularized it in the 1920s) is a framework that breaks down return on equity (ROE) into three multiplicative components: Net Profit Margin × Asset Turnover × Equity Multiplier. This decomposition reveals whether a company's ROE is driven by profitability, operational efficiency, or financial leverage — each with very different implications for quality and risk.
The three-way formula is: ROE = (Net Income/Revenue) × (Revenue/Total Assets) × (Total Assets/Shareholders' Equity). The first component (net margin) measures profitability — how many cents of profit the company earns per dollar of revenue. The second (asset turnover) measures efficiency — how many dollars of revenue the company generates per dollar of assets. The third (equity multiplier) measures leverage — how many dollars of assets are financed per dollar of equity.
Two companies can have identical 20% ROEs with very different underlying drivers. Company A might have a 20% margin, 0.5x turnover, and 2x leverage (a high-margin, asset-heavy business like luxury goods). Company B might have a 5% margin, 2x turnover, and 2x leverage (a low-margin, high-efficiency business like retail). Understanding the driver is crucial because ROE derived from high margins is generally more sustainable than ROE boosted by extreme leverage. The extended 5-factor DuPont model further decomposes the analysis by separating tax burden and interest burden, providing even deeper insight into what drives shareholder returns.
DuPont Analysis Example
- 1Walmart's ROE is driven primarily by high asset turnover (selling huge volumes) despite thin margins.
- 2Apple's ROE decomposition shows high margins (~25%), moderate turnover, and increasing leverage from buybacks.
- 3A bank with 15% ROE might rely heavily on 10x+ leverage, which DuPont analysis would immediately reveal.
