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. By way of learning-by-doing, we’ll look at ROE to gain a better understanding of China Petroleum & Chemical Corporation (HKG:386).
Over the last twelve months China Petroleum & Chemical has recorded a ROE of 11%. 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 I Calculate ROE?
The formula for return on equity is:
Return on Equity = Net Profit ÷ Shareholders’ Equity
Or for China Petroleum & Chemical:
11% = 71995 ÷ CN¥862b (Based on the trailing twelve months to September 2018.)
It’s easy to understand the ‘net profit’ part of that equation, but ‘shareholders’ equity’ requires further explanation. It is all earnings retained by the company, plus any capital paid in by shareholders. You can calculate shareholders’ equity by subtracting the company’s total liabilities from its total assets.
What Does Return On Equity Signify?
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 being equal, a high ROE is better than a low one. That means ROE can be used to compare two businesses.
Does China Petroleum & Chemical Have A Good Return On Equity?
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. The image below shows that China Petroleum & Chemical has an ROE that is roughly in line with the Oil and Gas industry average (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.

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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
