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 Guangdong Kanghua Healthcare Co Ltd (HKG:3689), by way of a worked example.
Over the last twelve months Guangdong Kanghua Healthcare has recorded a ROE of 13%. Another way to think of that is that for every HK$1 worth of equity in the company, it was able to earn HK$0.13.

How Do I Calculate Return On Equity?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders’ Equity
Or for Guangdong Kanghua Healthcare:
13% = CN¥170m ÷ CN¥1.4b (Based on the trailing twelve months to June 2018.)
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 earnings retained by the company, plus any capital paid in by shareholders. The easiest way to calculate shareholders’ equity is to subtract the company’s total liabilities from the total assets.
What Does ROE Mean?
ROE looks at the amount a company earns relative to the money it has kept within the business. The ‘return’ is the yearly profit. That means that the higher the ROE, the more profitable the company is. So, all else being equal, a high ROE is better than a low one. That means ROE can be used to compare two businesses.
Does Guangdong Kanghua Healthcare Have A Good ROE?
By comparing a company’s ROE with its industry average, we can get a quick measure of how good it is. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As you can see in the graphic below, Guangdong Kanghua Healthcare has a higher ROE than the average (7.3%) in the healthcare industry.
That’s what I like to see. We think a high ROE, alone, is usually enough to justify further research into a company. For example, I often check if insiders have been buying shares .
The Importance Of Debt To Return On Equity
Companies usually need to invest money to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. 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. That will make the ROE look better than if no debt was used.
