Learn what return on equity measures and why shareholders use it to compare
Return on equity (ROE) measures how much profit a company generates relative to shareholder equity. It is one of the most widely followed indicators of how effectively a business uses owners’ capital.
ROE matters because shareholders supply residual capital and expect returns above that capital’s opportunity cost. The number can improve through stronger profitability, better asset use, or more leverage, which is why analysts usually examine the drivers rather than treating the final ratio in isolation.
If a company earns $15 million and has $100 million of average shareholder equity, its ROE is 15%. If another company earns the same amount on only $60 million of equity, its ROE is higher, though leverage may be part of the story.
A shareholder says, “A high ROE always means the company has a great business model.”
Answer: Not always. High leverage can lift ROE even when the underlying business is not especially strong.
Return on Assets: ROA helps separate operating efficiency from leverage effects that can influence ROE.
Debt-to-Equity Ratio: Leverage can materially affect return on equity.
Return on Average Equity (ROAE): ROAE is a closely related variant that explicitly uses average equity in the denominator.
