Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). We'll use ROE to examine Petrofac Limited (LON:PFC), by way of a worked example.
Over the last twelve months Petrofac has recorded a ROE of 6.0%. That means that for every £1 worth of shareholders' equity, it generated £0.060 in profit.

How Do I Calculate Return On Equity?
The formula for ROE is:
Return on Equity = Net Profit ÷ Shareholders' Equity
Or for Petrofac:
6.0% = US$64m ÷ US$1.0b (Based on the trailing twelve months to December 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 the capital paid in by shareholders, plus any retained earnings. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.
What Does ROE Signify?
ROE measures a company's profitability against the profit it retains, and any outside investments. The 'return' is the yearly profit. The higher the ROE, the more profit the company is making. So, as a general rule, a high ROE is a good thing. That means ROE can be used to compare two businesses.
Does Petrofac Have A Good ROE?
One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. If you look at the image below, you can see Petrofac has a similar ROE to the average in the Energy Services industry classification (7.2%).
That's not overly surprising. ROE can give us a view about company quality, but many investors also look to other factors, such as whether there are insiders buying shares. If you are like me, then you will not want to miss this free list of growing companies that insiders are buying.
How Does Debt Impact ROE?
Companies usually need to invest money to grow their profits. That cash can come from retained earnings, issuing new shares (equity), 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. That will make the ROE look better than if no debt was used.
