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). We'll use ROE to examine Fortis Inc. (TSE:FTS), by way of a worked example.
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 other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.
How Do You Calculate Return On Equity?
ROE 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 Fortis is:
7.5% = CA$1.9b ÷ CA$26b (Based on the trailing twelve months to June 2025).
The 'return' is the income the business earned over the last year. One way to conceptualize this is that for each CA$1 of shareholders' capital it has, the company made CA$0.08 in profit.

Does Fortis 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. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As shown in the graphic below, Fortis has a lower ROE than the average (9.5%) in the Electric Utilities industry classification.
Unfortunately, that's sub-optimal. That being said, a low ROE is not always a bad thing, especially if the company has low leverage as this still leaves room for improvement if the company were to take on more debt. When a company has low ROE but high debt levels, we would be cautious as the risk involved is too high.

How Does Debt Impact Return On Equity?
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 used for growth will improve returns, but won't affect the total equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
Combining Fortis' Debt And Its 7.5% Return On Equity
Fortis clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.31. 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.
Conclusion
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. If two companies have the same ROE, then I would generally prefer the one with less debt.
But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider. So I think it may be worth checking this free report on analyst forecasts for the company.
