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 T-Mobile US, Inc. (NASDAQ:TMUS), by way of a worked example.

Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. Simply put, it is used to assess the profitability of a company in relation to its equity capital.

How Do You Calculate Return On Equity?

Return on equity 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 T-Mobile US is:

4.1% = US$2.7b ÷ US$66b (Based on the trailing twelve months to March 2021).

The 'return' is the yearly profit. That means that for every $1 worth of shareholders' equity, the company generated $0.04 in profit.

Does T-Mobile US Have A Good Return On Equity?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. The image below shows that T-Mobile US has an ROE that is roughly in line with the Wireless Telecom industry average (4.2%).

That's neither particularly good, nor bad. Although the ROE is similar to the industry, we should still perform further checks to see if the company's ROE is being boosted by high debt levels. If true, then it is more an indication of risk than the potential. You can see the 3 risks we have identified for T-Mobile US by visiting our risks dashboard for free on our platform here.

How Does Debt Impact ROE?

Virtually all companies need money to invest in the business, to grow profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. That will make the ROE look better than if no debt was used.

Combining T-Mobile US' Debt And Its 4.1% Return On Equity

It's worth noting the high use of debt by T-Mobile US, leading to its debt to equity ratio of 1.14. 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.

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. All else being equal, a higher ROE is better.

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. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
