Simply Wall St

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 Pinnacle West Capital Corporation (NYSE:PNW).

Over the last twelve months Pinnacle West Capital has recorded a ROE of 9.2%. That means that for every $1 worth of shareholders' equity, it generated $0.09 in profit.

How Do I Calculate Return On Equity?

The formula for return on equity is:

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

Or for Pinnacle West Capital:

9.2% = US$520m ÷ US$5.7b (Based on the trailing twelve months to September 2019.)

Most know that net profit is the total earnings after all expenses, but the concept of shareholders' equity is a little more complicated. It is all the money paid into the company from shareholders, plus any earnings retained. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.

What Does ROE Signify?

ROE measures a company's profitability against the profit it retains, and any outside investments. The 'return' is the amount earned after tax over the last twelve months. The higher the ROE, the more profit the company is making. So, as a general rule, a high ROE is a good thing. That means ROE can be used to compare two businesses.

Does Pinnacle West Capital 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. If you look at the image below, you can see Pinnacle West Capital has a similar ROE to the average in the Electric Utilities industry classification (9.0%).

That's neither particularly good, nor bad. ROE can give us a view about company quality, but many investors also look to other factors, such as whether there are insiders buying shares.

The Importance Of Debt To Return On Equity

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 and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. That will make the ROE look better than if no debt was used.

Pinnacle West Capital's Debt And Its 9.2% ROE

While Pinnacle West Capital does have some debt, with debt to equity of just 0.97, we wouldn't say debt is excessive. Its ROE isn't particularly impressive, but the debt levels are quite modest, so the business probably has some real potential. Conservative use of debt to boost returns is usually a good move for shareholders, though it does leave the company more exposed to interest rate rises.

The Key Takeaway

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.

But when a business is high quality, the market often bids it up to a price that reflects this. 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.
