How Do I Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for Shimao Property Holdings:

12% = CN¥8.8b ÷ CN¥105b (Based on the trailing twelve months to December 2018.)

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 earnings retained by the company, plus any capital paid in by shareholders. You can calculate shareholders' equity by subtracting the company's total liabilities from its total assets.

What Does ROE Signify?

ROE looks at the amount a company earns relative to the money it has kept within the business. The 'return' is the yearly profit. The higher the ROE, the more profit the company is making. So, all else being equal, a high ROE is better than a low one. That means it can be interesting to compare the ROE of different companies.

Does Shimao Property 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. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As is clear from the image below, Shimao Property Holdings has a better ROE than the average (9.1%) in the Real Estate industry.

That is a good sign. I usually take a closer look when a company has a better ROE than industry peers. One data point to check is if insiders have bought shares recently.

How Does Debt Impact 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 first and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders' equity. That will make the ROE look better than if no debt was used.

Shimao Property Holdings's Debt And Its 12% ROE

It's worth noting the significant use of debt by Shimao Property Holdings, leading to its debt to equity ratio of 1.20. while its ROE is respectable, it is worth keeping in mind that there is usually a limit to how much debt a company can use. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.

The Key Takeaway

Return on equity is one way we can compare the business quality of different companies. 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.
