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. To keep the lesson grounded in practicality, we’ll use ROE to better understand Mercury General Corporation (NYSE:MCY).
Mercury General has a ROE of 11%, based on the last twelve months. That means that for every $1 worth of shareholders’ equity, it generated $0.11 in profit.

How Do I Calculate Return On Equity?
The formula for ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders’ Equity
Or for Mercury General:
11% = US$207m ÷ US$1.8b (Based on the trailing twelve months to September 2019.)
It’s easy to understand the ‘net profit’ part of that equation, but ‘shareholders’ equity’ requires further explanation. It is all the money paid into the company from shareholders, plus any earnings retained. The easiest way to calculate shareholders’ equity is to subtract the company’s total liabilities from the 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 profit over the last twelve months. A higher profit will lead to a higher ROE. So, all else being equal, a high ROE is better than a low one. Clearly, then, one can use ROE to compare different companies.
Does Mercury General 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. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. Pleasingly, Mercury General has a superior ROE than the average (9.0%) company in the Insurance industry.
That is a good sign. I usually take a closer look when a company has a better ROE than industry peers. For example you might check if insiders are buying shares.
Why You Should Consider Debt When Looking At 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 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.
Combining Mercury General’s Debt And Its 11% Return On Equity
Although Mercury General does use debt, its debt to equity ratio of 0.21 is still low. The fact that it achieved a fairly good ROE with only modest debt suggests the business might be worth putting on your watchlist. Careful use of debt to boost returns is often very good for shareholders. However, it could reduce the company’s ability to take advantage of future opportunities.
In Summary
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.
