How DuPont Analysis Works
DuPont Analysis breaks down Return on Equity into three distinct components that reveal exactly what drives a company's shareholder returns. Net profit margin measures operational efficiency. Asset turnover measures how effectively the company uses its assets to generate sales. The equity multiplier measures financial leverage. Together these three ratios tell the complete story of ROE. Enter figures from a 10 K or earnings release to compare a retailer with thin margins and high turnover against a software firm with wide margins and lighter balance sheets. Compare DuPont components to direct competitor in same NAICS code not unrelated sector. One time write downs distort margin; normalize earnings before decomposition.
A company can achieve high ROE through different paths. A retailer might have thin margins but high asset turnover. A luxury brand might have high margins with lower turnover. A utility might have moderate margins and turnover but high leverage. DuPont Analysis helps you understand which path a company follows and whether its ROE is sustainable. Watch how a one point margin improvement flows through to ROE without any change in leverage or asset efficiency. One time write downs distort margin; normalize earnings before decomposition. Ten percent margin times one point two turnover times two times leverage yields twenty four percent ROE.

DuPont Formula
Net Profit Margin = Net Income / Revenue
Asset Turnover = Revenue / Total Assets
Equity Multiplier = Total Assets / Shareholder Equity
ROE = Net Profit Margin x Asset Turnover x Equity Multiplier
Verification: ROE = Net Income / Shareholder Equity
The three component decomposition was developed by the DuPont Corporation in the 1920s. It remains one of the most widely used financial analysis frameworks. Compare each component to industry medians, not absolute thresholds, when screening stocks. Ten percent margin times one point two turnover times two times leverage yields twenty four percent ROE.

FAQ
What is a good ROE?
A sustainable ROE of 15 to 20 percent is generally considered excellent. However ROE varies significantly by industry. Utilities and banks typically have lower ROE while technology and consumer brands often have higher ROE. Always compare against industry peers rather than absolute numbers. A bank at 12% ROE may be outperforming while a retailer at the same level may be lagging. Retail chains show high turnover low margin; luxury brands invert that DuPont profile. Compare DuPont components to direct competitor in same NAICS code not unrelated sector.
Which DuPont component is most important?
All three matter but the source matters for sustainability. High ROE driven by high profit margins and asset turnover is high quality and sustainable. High ROE driven primarily by a high equity multiplier (debt) is riskier because leverage amplifies both gains and losses. Flag companies where ROE rises while margins fall, a classic sign of financial engineering. Compare DuPont components to direct competitor in same NAICS code not unrelated sector. One time write downs distort margin; normalize earnings before decomposition.
How does debt affect DuPont analysis?
The equity multiplier increases with more debt. A company with 50 percent debt has an equity multiplier of 2.0 which doubles the ROE compared to an unlevered company. This shows why leverage makes returns look better but also increases financial risk. Rising interest rates can shrink margins while the multiplier stays high, compressing ROE from two directions. One time write downs distort margin; normalize earnings before decomposition. Ten percent margin times one point two turnover times two times leverage yields twenty four percent ROE.
Can DuPont analysis predict stock performance?
DuPont analysis is a diagnostic tool not a predictor. Companies with improving margins, stable turnover, and reasonable leverage tend to outperform over time. A deteriorating DuPont profile can be an early warning sign of competitive or operational problems. Pair it with free cash flow trends to confirm earnings quality behind the ROE headline. Ten percent margin times one point two turnover times two times leverage yields twenty four percent ROE. High ROE from leverage alone warrants balance sheet scrutiny before paying premium multiple.
How often should I run DuPont analysis?
Run it annually after each earnings report. Track the trend of all three components over 3 to 5 years. Improving margins, stable or improving turnover, and stable leverage suggest a healthy business. Declining margins with increasing leverage is a red flag. Re run after major acquisitions that change asset intensity overnight. High ROE from leverage alone warrants balance sheet scrutiny before paying premium multiple. Retail chains show high turnover low margin; luxury brands invert that DuPont profile. Compare DuPont components to direct competitor in same NAICS code not unrelated sector.
