How To 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 ACI Worldwide is:

15% = US$184m ÷ US$1.2b (Based on the trailing twelve months to June 2024).

The 'return' is the income the business earned over the last year. So, this means that for every $1 of its shareholder's investments, the company generates a profit of $0.15.

What Has ROE Got To Do With Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. 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.
