How Do You Calculate Return On Equity?

ROE 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 Diploma is:

13% = UK£117m ÷ UK£881m (Based on the trailing twelve months to March 2024).

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 £0.13 in profit.

What Has ROE Got To Do With Earnings Growth?

Depending on how much of these profits the company reinvests or "retains", and how effectively it does so, we are then able to assess a company’s earnings growth potential. 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.

Is Diploma Efficiently Re-investing Its Profits?

Besides, Diploma has been paying dividends for at least ten years or more. This shows that the company is committed to sharing profits with its shareholders. Upon studying the latest analysts' consensus data, we found that the company's future payout ratio is expected to drop to 37% over the next three years. Accordingly, the expected drop in the payout ratio explains the expected increase in the company's ROE to 18%, over the same period.
