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. We'll use ROE to examine Devro plc (LON:DVO), by way of a worked example.
Over the last twelve months Devro has recorded a ROE of 11%. Another way to think of that is that for every £1 worth of equity in the company, it was able to earn £0.11.

How Do I Calculate Return On Equity?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Devro:
11% = UK£15m ÷ UK£145m (Based on the trailing twelve months to June 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 the capital paid in by shareholders, plus any retained earnings. Shareholders' equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.
What Does ROE 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 yearly profit. 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 Devro Have A Good Return On Equity?
By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. If you look at the image below, you can see Devro has a similar ROE to the average in the Food industry classification (11%).
That isn't amazing, but it is respectable. ROE tells us about the quality of the business, but it does not give us much of an idea if the share price is cheap. I will like Devro better if I see some big insider buys. While we wait, check out this free list of growing companies with considerable, recent, insider buying.
How Does Debt Impact ROE?
Most companies need money -- from somewhere -- to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.
Combining Devro's Debt And Its 11% Return On Equity
Devro clearly uses a significant amount of debt to boost returns, as it has a debt to equity ratio of 1.12. There's no doubt the ROE is respectable, but it's worth keeping in mind that metric is elevated by the use of debt. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.
But It's Just One Metric
Return on equity is one way we can compare the business quality of different companies. Companies that can achieve high returns on equity without too much debt are generally of good quality. If two companies have the same ROE, then I would generally prefer the one with less debt.
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.
