How Do You Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

Or for Northland Power:

32% = CA$456m ÷ CA$1.4b (Based on the trailing twelve months to September 2019.)

Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. It is all the money paid into the company from shareholders, plus any earnings retained. You can calculate shareholders' equity by subtracting the company's total liabilities from its total assets.

What Does Return On Equity Signify?

ROE looks at the amount a company earns relative to the money it has kept within the business. The 'return' is the profit over the last twelve months. That means that the higher the ROE, the more profitable the company is. So, as a general rule, a high ROE is a good thing. Clearly, then, one can use ROE to compare different companies.

Does Northland Power Have A Good ROE?

Arguably the easiest way to assess company's ROE is to compare it with the average in 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 you can see in the graphic below, Northland Power has a higher ROE than the average (3.6%) in the Renewable Energy industry.

That's clearly a positive. We think a high ROE, alone, is usually enough to justify further research into a company. One data point to check is if insiders have bought shares recently.

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 case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the use of debt will improve the returns, but will not change the equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Northland Power's Debt And Its 32% ROE

It seems that Northland Power uses a lot of debt to fund the business, since it has a high debt to equity ratio of 5.42. Its ROE is no doubt quite impressive, but it would probably be a lot lower without the use of significant leverage.

The Bottom Line On ROE

Return on equity is one way we can compare the business quality of different companies. In my book the highest quality companies have high return on equity, despite low debt. 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. 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.
