### How Do I Calculate ROE?

The formula for return on equity is:

Return on Equity = Net Profit Ã· Shareholders' Equity

Or for Nan Nan Resources Enterprise:

16% = HK\$29m Ã· HK\$185m (Based on the trailing twelve months to March 2019.)

It's easy to understand the 'net profit' part of that equation, but 'shareholders' equity' requires further explanation. It is all earnings retained by the company, plus any capital paid in by shareholders. Shareholders' equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.

### What Does Return On Equity Mean?

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. That means it can be interesting to compare the ROE of different companies.

### Does Nan Nan Resources Enterprise 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. Pleasingly, Nan Nan Resources Enterprise has a superior ROE than the average (11%) company in the Oil and Gas industry.

That's what I like to see. 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 Return On Equity?

Virtually all companies need money to invest in the business, to grow profits. That cash can come from issuing shares, retained earnings, 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 use of debt will improve the returns, but will not change the equity. That will make the ROE look better than if no debt was used.

### Combining Nan Nan Resources Enterprise's Debt And Its 16% Return On Equity

It's worth noting the significant use of debt by Nan Nan Resources Enterprise, leading to its debt to equity ratio of 1.55. 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 increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.

### 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. 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.

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. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
