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. We'll use ROE to examine Schweitzer-Mauduit International, Inc. (NYSE:SWM), by way of a worked example.

Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.

How To Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for Schweitzer-Mauduit International is:

9.7% = US$63m ÷ US$653m (Based on the trailing twelve months to June 2021).

The 'return' is the amount earned after tax over the last twelve months. One way to conceptualize this is that for each $1 of shareholders' capital it has, the company made $0.10 in profit.

Does Schweitzer-Mauduit International 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. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. You can see in the graphic below that Schweitzer-Mauduit International has an ROE that is fairly close to the average for the Forestry industry (9.5%).

That's neither particularly good, nor bad. While at least the ROE is not lower than the industry, its still worth checking what role the company's debt plays as high debt levels relative to equity may also make the ROE appear high. If a company takes on too much debt, it is at higher risk of defaulting on interest payments.

How Does Debt Impact Return On Equity?

Companies usually need to invest money to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the first and second cases, the ROE will reflect this use of cash for investment in the business. 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.

Combining Schweitzer-Mauduit International's Debt And Its 9.7% Return On Equity

Schweitzer-Mauduit International clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.94. With a fairly low ROE, and significant use of debt, it's hard to get excited about this business at the moment. Investors should think carefully about how a company might perform if it was unable to borrow so easily, because credit markets do change over time.

Conclusion

Return on equity is useful for comparing the quality of different businesses. In our books, 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.

But when a business is high quality, the market often bids it up to a price that reflects this. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
