Did You Know?
How Does ROE Work?
The Formula
ROE = Net Income / Shareholders' Equity × 100. It answers: for every dollar of equity, how much profit does the company generate for owners?
DuPont Decomposition
ROE = (Net Income / Revenue) × (Revenue / Total Assets) × (Total Assets / Equity) = Profit Margin × Asset Turnover × Equity Multiplier. Each factor can boost ROE: higher margins, better asset use, or more leverage.
Leverage Effect
Equity Multiplier = Total Assets / Equity. More debt means smaller equity denominator, inflating ROE. Compare ROE to ROA — if ROE is much higher, leverage is doing the work.

Frequently Asked Questions
What is Return on Equity?
ROE measures profitability relative to shareholders' investment. ROE = Net Income / Equity × 100. A 15% ROE means $15 profit per $100 of equity. It's the most watched profitability metric by equity investors.
What is a good ROE?
S&P 500 average: ~15-17%. Tech: 20-30%. Banks: 10-15%. Utilities: 8-12%. Warren Buffett looks for consistent 15%+ ROE. Very high ROE (30%+) may signal excessive leverage.
What is the DuPont analysis of ROE?
ROE = Profit Margin × Asset Turnover × Equity Multiplier. This decomposes ROE into profitability, efficiency, and leverage. A company can boost ROE through any of these three levers.
How does debt affect ROE?
More debt means less equity, inflating ROE. A company with 50% debt/equity has higher ROE than an all-equity company with the same profits. This is why ROE should be analyzed alongside debt ratios.
Why is ROE more important than ROA?
ROE reflects returns to equity holders (the owners). ROA measures total asset efficiency. Investors own equity, not assets, so ROE directly measures their return. But ROA shows operating efficiency without leverage effects.
Can ROE be misleading?
Yes. Negative equity (from buybacks or losses) makes ROE meaningless. High debt inflates ROE artificially. One-time gains distort it. Always use DuPont decomposition and compare to ROA.
