How Do You Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for In Technical Productions Holdings:

8.2% = HK$11m ÷ HK$130m (Based on the trailing twelve months to August 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 Mean?

ROE looks at the amount a company earns relative to the money it has kept within the business. The 'return' is the yearly profit. 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. That means ROE can be used to compare two businesses.

Does In Technical Productions 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. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. You can see in the graphic below that In Technical Productions Holdings has an ROE that is fairly close to the average for the Entertainment industry (9.5%).

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.

Why You Should Consider Debt When Looking At ROE

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 use of debt will improve the returns, but will not change the equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

Combining In Technical Productions Holdings's Debt And Its 8.2% Return On Equity

In Technical Productions Holdings has a debt to equity ratio of just 0.052, which is very low. Although the ROE isn't overly impressive, the debt load is modest, suggesting the business has 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.

But It's Just One Metric

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. A company that can achieve a high return on equity without debt could be considered a high quality business. If two companies have around the same level of debt to equity, and one has a higher ROE, I'd generally prefer the one with higher ROE.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
