ROE

Return on Equity (ROE) measures how efficiently a company uses shareholders' capital to generate profit. It is expressed as a percentage and calculated by dividing net income by average shareholders' equity. ROE is a key metric in fundamental analysis for assessing profitability and capital efficiency.

How It Works

To calculate ROE, take the company's net income from the income statement for a given period. Then obtain the shareholders' equity figure from the balance sheet, preferably the average of beginning and ending equity for the period. Divide net income by average equity and multiply by 100 to get a percentage. For example, if net income is $2 million and average equity is $10 million, ROE equals 20%.

ROE can be broken down using the DuPont analysis into three components: profit margin, asset turnover, and financial leverage. This decomposition helps identify whether high ROE stems from strong earnings, efficient use of assets, or high debt levels.

If a company has a profit margin of 8%, asset turnover of 1.2, and equity multiplier of 2.0, its ROE equals 8% × 1.2 × 2.0 = 19.2%.

ROE can be inflated by share buybacks or accounting adjustments that reduce equity without improving underlying profitability. Analysts therefore complement ROE with other ratios such as Return on Assets (ROA) and debt-to-equity to obtain a fuller picture.

Why It Matters

Investors use ROE to compare the profitability of companies within the same industry. A consistently high ROE suggests management is effective at generating returns on invested capital.
