While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. To keep the lesson grounded in practicality, we'll use ROE to better understand ReadyTech Holdings Limited (ASX:RDY).

Our data shows ReadyTech Holdings has a return on equity of 4.1% for the last year. That means that for every A$1 worth of shareholders' equity, it generated A$0.04 in profit.

How Do I Calculate Return On Equity?

The formula for ROE is:

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

Or for ReadyTech Holdings:

4.1% = AU$1.3m ÷ AU$31m (Based on the trailing twelve months to December 2019.)

Most know that net profit is the total earnings after all expenses, but the concept of shareholders' equity is a little more complicated. It is all the money paid into the company from shareholders, plus any earnings retained. Shareholders' equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.

What Does Return On Equity Mean?

ROE measures a company's profitability against the profit it retains, and any outside investments. The 'return' is the profit over the last twelve months. A higher profit will lead to a higher ROE. So, all else equal, investors should like a high ROE. That means it can be interesting to compare the ROE of different companies.

Does ReadyTech Holdings Have A Good ROE?

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As is clear from the image below, ReadyTech Holdings has a lower ROE than the average (15%) in the Software industry.

That certainly isn't ideal. It is better when the ROE is above industry average, but a low one doesn't necessarily mean the business is overpriced. Still, shareholders might want to check if insiders have been selling.

How Does Debt Impact ROE?

Companies usually need to invest money to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the first and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
