Return on Average Equity (ROAE)

Return on Average Equity (ROAE)

Return on Average Equity (ROAE) is a profitability ratio that measures how effectively a company uses its average shareholders’ equity to generate net income over a fiscal period (typically one year). It smooths out timing differences in equity changes by using the average of beginning and ending shareholders’ equity.

Definition and formula

ROAE = Net income / Average shareholders’ equity

Average shareholders’ equity = (Beginning equity + Ending equity) / 2

Net income is reported on the income statement; shareholders’ equity appears on the balance sheet. Because the income statement covers a period while the balance sheet is a single-date snapshot, averaging equity provides a more representative denominator when equity changes during the year.

Example

• Beginning shareholders’ equity: $1,000,000
• Ending shareholders’ equity: $1,500,000
• Average shareholders’ equity = ($1,000,000 + $1,500,000) / 2 = $1,250,000
• Net income: $200,000
• ROAE = $200,000 / $1,250,000 = 16%

How ROAE differs from ROE

Return on Equity (ROE) typically uses ending shareholders’ equity as the denominator (Net income / Ending equity). If equity changes significantly during the year (due to new share issuances, buybacks, dividends, etc.), ROE can be distorted. ROAE mitigates this by using an average equity figure. If equity is stable, ROE and ROAE will be similar.

Decomposing ROAE (DuPont-style)

ROAE can be understood through three components:
– Profit margin = Net income / Sales (measures profitability)
– Asset turnover = Sales / Average total assets (measures asset efficiency)
– Financial leverage = Average total assets / Average shareholders’ equity (measures use of debt)

ROAE ≈ Profit margin × Asset turnover × Financial leverage

This decomposition helps identify whether ROAE is driven by operating performance, asset use, or leverage.

Interpretation and limitations

• A higher ROAE indicates a company generates more net income per dollar of equity, which is generally positive.
• High ROAE can result from:
• Strong operational profitability (good),
• Efficient use of assets (good),
• Increased financial leverage (riskier),
• One-time gains or asset sales (transient).
• Compare ROAE among companies in the same industry and consider the capital structure. High leverage can amplify ROAE but increases financial risk.
• Use ROAE alongside other metrics (profit margin, return on assets, debt ratios) to get a fuller picture.

Practical use

• Use ROAE to evaluate management’s efficiency at deploying shareholders’ capital.
• Prefer ROAE over ROE when equity fluctuates materially during the period.
• Benchmark against peers and historical company performance to assess trends and sustainability.
