How Do You 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 Beacon Roofing Supply is:

20% = US$373m ÷ US$1.9b (Based on the trailing twelve months to September 2024).

The 'return' is the yearly profit. So, this means that for every $1 of its shareholder's investments, the company generates a profit of $0.20.

Does Beacon Roofing Supply 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. As is clear from the image below, Beacon Roofing Supply has a better ROE than the average (16%) in the Trade Distributors industry.

That's clearly a positive. 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.

How Does Debt Impact ROE?

Most companies need money -- from somewhere -- to grow their 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. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Beacon Roofing Supply's Debt And Its 20% ROE

Beacon Roofing Supply clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.55. There's no doubt its ROE is decent, but the very high debt the company carries is not too exciting to see. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.
