Simply Wall St

One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. We'll use ROE to examine Allegion plc (NYSE:ALLE), by way of a worked example.

Over the last twelve months Allegion has recorded a ROE of 66%. That means that for every $1 worth of shareholders' equity, it generated $0.66 in profit.

How Do I Calculate ROE?

The formula for return on equity is:

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

Or for Allegion:

66% = US$454m ÷ US$687m (Based on the trailing twelve months to September 2019.)

Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. It is all earnings retained by the company, plus any capital paid in by shareholders. 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?

Return on Equity measures a company's profitability against the profit it has kept for the business (plus any capital injections). The 'return' is the amount earned after tax over the last twelve months. The higher the ROE, the more profit the company is making. So, all else equal, investors should like a high ROE. Clearly, then, one can use ROE to compare different companies.

Does Allegion Have A Good ROE?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As is clear from the image below, Allegion has a better ROE than the average (12%) in the Building industry.

That's what I like to see. In my book, a high ROE almost always warrants a closer look. One data point to check is if insiders have bought shares recently.

How Does Debt Impact Return On Equity?

Most companies need money -- from somewhere -- to grow their profits. That cash can come from retained earnings, issuing new shares (equity), 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 use of debt will improve the returns, but will not change the equity. That will make the ROE look better than if no debt was used.

Combining Allegion's Debt And Its 66% Return On Equity

Allegion clearly uses a significant amount of debt to boost returns, as it has a debt to equity ratio of 2.08. There's no doubt its ROE is impressive, but the company appears to use its debt to boost that metric. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.

The Key Takeaway

Return on equity is one way we can compare the business quality of different companies. A company that can achieve a high return on equity without debt could be considered a high quality business. All else being equal, a higher ROE is better.

Having said that, while ROE is a useful indicator of business quality, you'll have to look at a whole range of factors to determine the right price to buy a stock. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too.
