A: A DuPont Analysis Calculator decomposes Return on Equity (ROE) into three components: Net Profit Margin (profitability), Total Asset Turnover (efficiency), and Equity Multiplier (leverage). Enter four inputs — revenue, net profit, total assets, and equity — and get your ROE breakdown instantly. No spreadsheet required.
A: The 3-component DuPont formula is:
ROE = Net Profit Margin × Total Asset Turnover × Equity Multiplier
- Net Profit Margin = Net Profit ÷ Revenue
- Total Asset Turnover = Revenue ÷ Average Total Assets
- Equity Multiplier = Average Total Assets ÷ Average Total Equity
Multiply all three. The result is your ROE — expressed as a percentage.
A: A ROE above 15% is generally considered strong across most industries. However, DuPont analysis matters because it shows why ROE is high. A 20% ROE driven by high profit margins signals a healthy business. The same ROE driven purely by a high equity multiplier (heavy debt) signals financial risk. Always read all three components together.
A: The equity multiplier amplifies ROE by reflecting financial leverage. A multiplier of 3x means the company uses $3 of assets for every $1 of equity. Higher leverage boosts ROE — but also increases default risk. For personal FIRE planning, a low equity multiplier in your portfolio holdings often signals a more debt-resilient company worth holding long-term.
A: Yes — and it's underused. FIRE investors use DuPont analysis to evaluate whether a stock's ROE is sustainably high before adding it to a dividend or index portfolio. If a company's ROE depends on shrinking equity rather than genuine profit growth, it's a red flag. Run the numbers before you commit capital.
A: The 3-component model (this calculator) uses: Profit Margin × Asset Turnover × Equity Multiplier. The 5-component model splits profit margin further into tax burden, interest burden, and EBIT margin, and splits asset turnover into asset turnover and financial leverage. The 3-component version is faster and sufficient for most stock screening and personal finance decisions.
A: Increasing Average Total Assets while holding net profit constant lowers your Total Asset Turnover — which directly compresses ROE. This is the efficiency trap: more assets don't automatically mean more returns. Companies (and portfolios) that generate high revenue relative to their asset base score higher on this metric and tend to compound wealth more efficiently over time.
