DuPont Analysis
DuPont analysis: ROE = Net Profit Margin x Asset Turnover x Equity Multiplier.
Decompose return on equity into three driving components.
The Formula
ROE = (Net Income / Revenue) × (Revenue / Total Assets) × (Total Assets / Equity)
DuPont analysis is a framework that breaks down Return on Equity (ROE) into three distinct components, each representing a different dimension of financial performance. Developed by the DuPont Corporation in the 1920s, this method allows analysts and managers to identify the specific drivers behind a company's ROE — making it far more informative than looking at ROE as a single number. Two companies can have the same ROE through completely different routes: one through high profit margins, another through high asset efficiency, and a third through heavy use of financial leverage.
The first component, Net Profit Margin, measures how much profit the company keeps from each dollar of revenue. It reflects pricing power, cost control, and operational efficiency. A retailer operating on thin margins might still achieve strong ROE through the other two components.
The second component, Asset Turnover, measures how efficiently the company uses its assets to generate revenue. A high asset turnover means the company is extracting more revenue per dollar of assets deployed. Capital-intensive industries like utilities tend to have low turnover, while retailers and service businesses typically have high turnover.
The third component, the Equity Multiplier, reflects financial leverage — how much of the company's assets are financed by debt versus equity. A higher multiplier means more debt. While leverage can amplify ROE, it also increases financial risk. DuPont analysis makes this leverage effect visible, allowing analysts to judge whether high ROE is earned through genuine operational strength or simply borrowed from creditors.
Variables
| Symbol | Meaning | Unit |
|---|---|---|
| ROE | Return on Equity — net income divided by shareholders equity | % or ratio |
| Net Profit Margin | Net Income / Revenue — profit kept per dollar of revenue | % or ratio |
| Asset Turnover | Revenue / Total Assets — revenue generated per dollar of assets | ratio |
| Equity Multiplier | Total Assets / Equity — leverage ratio showing debt usage | ratio |
Example 1
A company has Net Income = $5M, Revenue = $50M, Total Assets = $40M, and Total Equity = $20M. Calculate the DuPont ROE.
Net Profit Margin = $5M / $50M = 10%
Asset Turnover = $50M / $40M = 1.25
Equity Multiplier = $40M / $20M = 2.0
ROE = 10% × 1.25 × 2.0 = 25%
ROE = 25%, driven equally by solid margins, efficient asset use, and moderate leverage
Example 2
Two companies both have ROE = 20%. Company A: Margin = 20%, Turnover = 1.0, Multiplier = 1.0. Company B: Margin = 2%, Turnover = 2.0, Multiplier = 5.0. What does DuPont analysis reveal?
Company A ROE = 20% × 1.0 × 1.0 = 20% (zero debt, pure profitability)
Company B ROE = 2% × 2.0 × 5.0 = 20% (thin margins, high leverage)
Same ROE, very different risk profiles — Company B relies heavily on debt to achieve its returns
When to Use It
DuPont analysis is used by:
- Financial analysts comparing companies within the same industry
- Corporate managers diagnosing what is driving or limiting ROE improvement
- Investors evaluating the quality and sustainability of a company's returns
- Credit analysts assessing whether high ROE comes from operational strength or excess leverage
- Strategy consultants benchmarking business unit performance across a conglomerate
- Business school coursework and CFA exam preparation in financial statement analysis
