How Do You Calculate Return On Equity?

The formula for ROE is:

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

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

9.5% = CN¥467m ÷ CN¥4.9b (Based on the trailing twelve months to March 2023).

The 'return' is the yearly profit. That means that for every CN¥1 worth of shareholders' equity, the company generated CN¥0.09 in profit.

Why Is ROE Important For Earnings Growth?

Thus far, we have learned that ROE measures how efficiently a company is generating its profits. We now need to evaluate how much profit the company reinvests or "retains" for future growth which then gives us an idea about the growth potential of the company. Assuming everything else remains unchanged, the higher the ROE and profit retention, the higher the growth rate of a company compared to companies that don't necessarily bear these characteristics.

We then compared Jilin Expressway's net income growth with the industry and we're pleased to see that the company's growth figure is higher when compared with the industry which has a growth rate of 4.1% in the same period.
