Return on Equity (ROE) Calculator
Return on Equity (ROE) Calculator
ROE is one of the most-watched profitability ratios for investors, since it directly measures how effectively management turns shareholders' invested capital into profit. Unlike ROA, it excludes the effect of financing structure on assets — it looks purely at return relative to equity.
Investors and analysts compare ROE across companies in the same industry to judge management efficiency and capital allocation.
- Formula: ROE = Net Income ÷ Shareholders' Equity × 100.
- Rule of thumb: an ROE in the 15-20% range is often considered strong, though "good" varies significantly by industry and market conditions.
- Watch for leverage effects: a company can artificially boost ROE by taking on more debt (reducing equity) rather than genuinely improving profitability — always check the debt-to-equity ratio alongside ROE.
What's the difference between ROE and ROA?
ROE measures return relative to shareholders' equity only; ROA measures return relative to total assets (equity plus debt). A company with high debt can show high ROE but modest ROA — comparing both gives a fuller picture.
Should I use average equity instead of period-end equity?
For deeper analysis, many analysts use average equity over the period (beginning + ending, divided by two) to smooth out mid-year swings — this calculator uses a single equity figure for simplicity, which is standard for a quick estimate.
