How Do I Calculate ROE?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders’ Equity

Or for CMS Energy:

14% = US$657m ÷ US$4.8b (Based on the trailing twelve months to December 2018.)

It’s easy to understand the ‘net profit’ part of that equation, but ‘shareholders’ equity’ requires further explanation. It is the capital paid in by shareholders, plus any retained earnings. 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 amount earned after tax 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 CMS Energy 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. As is clear from the image below, CMS Energy has a better ROE than the average (10%) in the Integrated Utilities industry.

That’s clearly a positive. We think a high ROE, alone, is usually enough to justify further research into a company. One data point to check is if insiders have bought shares recently.

The Importance Of Debt To Return On Equity

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 first and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the use of debt will improve the returns, but will not change the equity. That will make the ROE look better than if no debt was used.

CMS Energy’s Debt And Its 14% ROE

CMS Energy clearly uses a significant amount of debt to boost returns, as it has a debt to equity ratio of 2.46. Its ROE is quite good but, it would have probably been lower without the use of debt. Debt does bring extra risk, so it’s only really worthwhile when a company generates some decent returns from it.

But It’s Just One Metric

Return on equity is useful for comparing the quality of different businesses. Companies that can achieve high returns on equity without too much debt are generally of good quality. All else being equal, a higher ROE is better.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. It is important to consider other factors, such as future profit growth — and how much investment is required going forward.
