How Do You Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders’ Equity

Or for Phoslock Environmental Technologies:

0.8% = 0.001304 ÷ AU$14m (Based on the trailing twelve months to June 2018.)

It’s easy to understand the ‘net profit’ part of that equation, but ‘shareholders’ equity’ requires further explanation. It is the capital paid in by shareholders, plus any retained earnings. You can calculate shareholders’ equity by subtracting the company’s total liabilities from its total assets.

What Does Return On Equity Signify?

Return on Equity measures a company’s profitability against the profit it has kept for the business (plus any capital injections). The ‘return’ is the amount earned after tax over the last twelve months. That means that the higher the ROE, the more profitable the company is. So, all else equal, investors should like a high ROE. That means ROE can be used to compare two businesses.

Does Phoslock Environmental Technologies 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. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As shown in the graphic below, Phoslock Environmental Technologies has a lower ROE than the average (8.8%) in the Commercial Services industry classification.

That’s not what we like to see. We prefer it when the ROE of a company is above the industry average, but it’s not the be-all and end-all if it is lower. Nonetheless, it might be wise to check if insiders have been selling.

The Importance Of Debt To Return On Equity

Companies usually need to invest money to grow their profits. That cash can come from retained earnings, issuing new shares (equity), or debt. 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.

Phoslock Environmental Technologies’s Debt And Its 0.8% ROE

While Phoslock Environmental Technologies does have a tiny amount of debt, with debt to equity of just 0.022, we think the use of debt is very modest. Its ROE is certainly on the low side, and since it already uses debt, we’re not too excited about the company. 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.

In Summary

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 when a business is high quality, the market often bids it up to a price that reflects this. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
