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 Southwest Gas Holdings, Inc. (NYSE:SWX).
Our data shows Southwest Gas Holdings has a return on equity of 7.7% for the last year. That means that for every $1 worth of shareholders’ equity, it generated $0.08 in profit.
How Do I Calculate ROE?
The formula for ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders’ Equity
Or for Southwest Gas Holdings:
7.7% = US$194m ÷ US$2.5b (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 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?
ROE measures a company’s profitability against the profit it retains, and any outside investments. The ‘return’ is the yearly profit. That means that the higher the ROE, the more profitable the company is. So, all else equal, investors should like a high ROE. Clearly, then, one can use ROE to compare different companies.
Does Southwest Gas Holdings 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. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. The image below shows that Southwest Gas Holdings has an ROE that is roughly in line with the Gas Utilities industry average (8.3%).
That isn’t amazing, but it is respectable. 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. If you like to buy stocks alongside management, then you might just love this free list of companies.

The Importance Of Debt To Return On Equity
Virtually all companies need money to invest in the business, to grow 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. That will make the ROE look better than if no debt was used.
Combining Southwest Gas Holdings’s Debt And Its 7.7% Return On Equity
It’s worth noting the significant use of debt by Southwest Gas Holdings, leading to its debt to equity ratio of 1.01. The company doesn’t have a bad ROE, but it is less than ideal tht it has had to use debt to achieve its returns. Debt does bring extra risk, so it’s only really worthwhile when a company generates some decent returns from it.
The Key Takeaway
Return on equity is one way we can compare the business quality of different companies. In my book the highest quality companies have high return on equity, despite low debt. 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. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
