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. We'll use ROE to examine Jilin Electric Power Co.,Ltd. (SZSE:000875), by way of a worked example.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors' money. In short, ROE shows the profit each dollar generates with respect to its shareholder investments.

How Do You Calculate Return On Equity?

ROE can be calculated by using the formula:

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

So, based on the above formula, the ROE for Jilin Electric PowerLtd is:

5.3% = CN¥785m ÷ CN¥15b (Based on the trailing twelve months to March 2022).

The 'return' refers to a company's earnings over the last year. That means that for every CN¥1 worth of shareholders' equity, the company generated CN¥0.05 in profit.

Does Jilin Electric PowerLtd 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. You can see in the graphic below that Jilin Electric PowerLtd has an ROE that is fairly close to the average for the Renewable Energy industry (6.1%).

That isn't amazing, but it is respectable. Even if the ROE is respectable when compared to the industry, its worth checking if the firm's ROE is being aided by high debt levels. If a company takes on too much debt, it is at higher risk of defaulting on interest payments.

The Importance Of Debt To Return On Equity

Virtually all companies need money to invest in the business, to grow profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the first two cases, the ROE will capture this use of capital to grow. 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.

Jilin Electric PowerLtd's Debt And Its 5.3% ROE

We think Jilin Electric PowerLtd uses a significant amount of debt to maximize its returns, as it has a significantly higher debt to equity ratio of 3.04. The combination of a rather low ROE and high debt to equity is a negative, in our book.

Summary

Return on equity is useful for comparing the quality of different businesses. A company that can achieve a high return on equity without debt could be considered a high quality business. If two companies have the same ROE, then I would generally prefer the one with less debt.

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. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
