Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). By way of learning-by-doing, we'll look at ROE to gain a better understanding of T-Mobile US, Inc. (NASDAQ:TMUS).
ROE or return on equity is a useful tool to assess how effectively a company can generate returns on the investment it received from its shareholders. 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 T-Mobile US is:
2.2% = US$1.5b ÷ US$70b (Based on the trailing twelve months to September 2022).
The 'return' is the profit over the last twelve months. One way to conceptualize this is that for each $1 of shareholders' capital it has, the company made $0.02 in profit.
Does T-Mobile US 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. 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, T-Mobile US has a lower ROE than the average (6.4%) in the Wireless Telecom industry.
That's not what we like to see. However, a low ROE is not always bad. If the company's debt levels are moderate to low, then there's still a chance that returns can be improved via the use of financial leverage. A high debt company having a low ROE is a different story altogether and a risky investment in our books. Our risks dashboard should have the 4 risks we have identified for T-Mobile US.
Why You Should Consider Debt When Looking At ROE
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 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.
T-Mobile US' Debt And Its 2.2% ROE
T-Mobile US clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.05. The combination of a rather low ROE and significant use of debt is not particularly appealing. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.
