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 Hertz Global Holdings is:

78% = US$2.1b ÷ US$2.6b (Based on the trailing twelve months to December 2022).

The 'return' is the amount earned after tax 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 $0.78 in profit.

Does Hertz Global Holdings 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. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As is clear from the image below, Hertz Global Holdings has a better ROE than the average (26%) in the Transportation industry.

That's what we like to see. Bear in mind, a high ROE doesn't always mean superior financial performance. A higher proportion of debt in a company's capital structure may also result in a high ROE, where the high debt levels could be a huge risk .

Why You Should Consider Debt When Looking At ROE

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

Hertz Global Holdings' Debt And Its 78% ROE

It seems that Hertz Global Holdings uses a huge volume of debt to fund the business, since it has an extremely high debt to equity ratio of 5.24. Its ROE is clearly quite good, but it seems to be boosted by the significant use of debt by the company.

Conclusion

Return on equity is useful for comparing the quality of different businesses. Companies that can achieve high returns on equity without too much debt are generally of good quality. All else being equal, a higher ROE is better.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too.
