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. By way of learning-by-doing, we'll look at ROE to gain a better understanding of China Xinhua Education Group Limited (HKG:2779).

Our data shows China Xinhua Education Group has a return on equity of 11% for the last year. One way to conceptualize this, is that for each HK$1 of shareholders' equity it has, the company made HK$0.11 in profit.

How Do You Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for China Xinhua Education Group:

11% = CN¥271m ÷ CN¥2.5b (Based on the trailing twelve months to June 2019.)

It's easy to understand the 'net profit' part of that equation, but 'shareholders' equity' requires further explanation. 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 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. 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 China Xinhua Education Group 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. You can see in the graphic below that China Xinhua Education Group has an ROE that is fairly close to the average for the Consumer Services industry (13%).

That's neither particularly good, nor bad. ROE doesn't tell us if the share price is low, but it can inform us to the nature of the business. For those looking for a bargain, other factors may be more important. I will like China Xinhua Education Group better if I see some big insider buys.

How Does Debt Impact Return On Equity?

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 required for growth will boost returns, but will not impact the shareholders' equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

The Bottom Line On ROE

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. If two companies have around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.

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. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
