How Do You Calculate Return On Equity?

The 'return' refers to a company's earnings over the last year. That means that for every ￡1 worth of shareholders' equity, the company generated ￡0.14 in profit.

What Has ROE Got To Do With Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. Based on how much of its profits the company chooses to reinvest or "retain", we are then able to evaluate a company's future ability to generate profits. Assuming everything else remains unchanged, the higher the ROE and profit retention, the higher the growth rate of a company compared to companies that don't necessarily bear these characteristics.
