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 New Hope Dairy Co., Ltd. (SZSE:002946).

ROE or return on equity is a useful tool to assess how effectively a company can generate returns on the investment it received from its shareholders. Put another way, it reveals the company's success at turning shareholder investments into profits.

How Is ROE Calculated?

The formula for return on equity is:

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

So, based on the above formula, the ROE for New Hope Dairy is:

16% = CN¥438m ÷ CN¥2.7b (Based on the trailing twelve months to September 2023).

The 'return' is the income the business earned over the last year. That means that for every CN¥1 worth of shareholders' equity, the company generated CN¥0.16 in profit.

Does New Hope Dairy Have A Good ROE?

By comparing a company's ROE with its industry average, we can get a quick measure of how good it is. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. Pleasingly, New Hope Dairy has a superior ROE than the average (8.5%) in the Food industry.

That's clearly a positive. However, bear in mind that a high ROE doesn't necessarily indicate efficient profit generation. Especially when a firm uses high levels of debt to finance its debt which may boost its ROE but the high leverage puts the company at risk.

How Does Debt Impact ROE?

Virtually all companies need money to invest in the business, to grow 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. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

New Hope Dairy's Debt And Its 16% ROE

New Hope Dairy does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.39. While its ROE is respectable, it is worth keeping in mind that there is usually a limit as 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.

Summary

Return on equity is one way we can compare its business quality of different companies. 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. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
