How Is ROE Calculated?

Return on equity can be calculated by using the formula:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for Serco Group is:

20% = UK￡202m ÷ UK￡1.0b (Based on the trailing twelve months to December 2023).

The 'return' refers to a company's earnings over the last year. Another way to think of that is that for every ￡1 worth of equity, the company was able to earn ￡0.20 in profit.

What Is The Relationship Between ROE And Earnings Growth?

We have already established that ROE serves as an efficient profit-generating gauge for a company's future earnings. We now need to evaluate how much profit the company reinvests or "retains" for future growth which then gives us an idea about the growth potential of the company. 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.
