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. To keep the lesson grounded in practicality, we'll use ROE to better understand Targa Resources Corp. (NYSE:TRGP).

Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.

How Is ROE Calculated?

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 Targa Resources is:

20% = US$895m ÷ US$4.4b (Based on the trailing twelve months to June 2022).

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 $0.20.

Does Targa Resources 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. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As shown in the graphic below, Targa Resources has a lower ROE than the average (26%) in the Oil and Gas industry classification.

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.

How Does Debt Impact Return On Equity?

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 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. That will make the ROE look better than if no debt was used.

Combining Targa Resources' Debt And Its 20% Return On Equity

Targa Resources does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.69. While its ROE is respectable, it is worth keeping in mind that there is usually a limit as to how much debt a company can use. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.

Conclusion

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. Companies that can achieve high returns on equity without too much debt are generally of good quality. 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.
