By way of learning-by-doing, we'll look at ROE to gain a better understanding of WH Smith PLC (LON:SMWH).

Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How Do You Calculate Return On Equity?

The formula for ROE is:

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

So, based on the above formula, the ROE for WH Smith is:

26% = UK£88m ÷ UK£340m (Based on the trailing twelve months to August 2023).

The 'return' refers to a company's earnings over the last year. So, this means that for every £1 of its shareholder's investments, the company generates a profit of £0.26.

Does WH Smith 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. As you can see in the graphic below, WH Smith has a higher ROE than the average (15%) in the Specialty Retail industry. roe

That is a good sign. With that said, a high ROE doesn't always indicate high profitability. Especially when a firm uses high levels of debt to finance its debt which may boost its ROE but the high leverage puts the company at risk.

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 issuing shares, retained earnings, 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.

WH Smith's Debt And Its 26% ROE

WH Smith does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.13. While no doubt that its ROE is impressive, we would have been even more impressed had the company achieved this with lower debt. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.



Summary

Return on equity is useful for comparing the quality of different businesses. A company that can achieve a high return on equity without debt could be considered a high quality business. If two companies have the same ROE, then I would generally prefer the one with less debt.

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. So I think it may be worth checking this freereport on analyst forecasts for the company.

Of course WH Smith may not be the best stock to buy. So you may wish to see this free collection of other companies that have high ROE and low debt.
