How To Calculate Return On Equity?

ROE can be calculated by using the formula:

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

So, based on the above formula, the ROE for Armstrong World Industries is:

36% = US$189m ÷ US$528m (Based on the trailing twelve months to June 2022).

The 'return' is the profit over the last twelve months. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.36 in profit.

Does Armstrong World Industries Have A Good ROE?

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As you can see in the graphic below, Armstrong World Industries has a higher ROE than the average (24%) in the Building industry.

That is a good sign. However, bear in mind that a high ROE doesn’t necessarily indicate efficient profit generation. Aside from changes in net income, a high ROE can also be the outcome of high debt relative to equity, which indicates risk.

Why You Should Consider Debt When Looking At ROE

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 first two cases, the ROE will capture this use of capital to grow. 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.

Combining Armstrong World Industries' Debt And Its 36% Return On Equity

Armstrong World Industries does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.27. While no doubt that its ROE is impressive, we would have been even more impressed had the company achieved this with lower debt. 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.

Summary

Return on equity is one way we can compare its 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 the same ROE, then I would generally prefer the one with less debt.

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. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
