How Is ROE Calculated?

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 Renewable Japan is:

4.3% = JP¥611m ÷ JP¥14b (Based on the trailing twelve months to March 2024).

The 'return' is the profit over the last twelve months. Another way to think of that is that for every ¥1 worth of equity, the company was able to earn ¥0.04 in profit.

Does Renewable Japan 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. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. If you look at the image below, you can see Renewable Japan has a lower ROE than the average (5.6%) in the Renewable Energy industry classification.

That's not what we like to see. That being said, a low ROE is not always a bad thing, especially if the company has low leverage as this still leaves room for improvement if the company were to take on more debt. A company with high debt levels and low ROE is a combination we like to avoid given the risk involved. To know the 2 risks we have identified for Renewable Japan visit our risks dashboard for free.

Why You Should Consider Debt When Looking At ROE

Companies usually need to invest money to grow their profits. That cash can come from retained earnings, issuing new shares (equity), 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. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Renewable Japan's Debt And Its 4.3% ROE

It appears that Renewable Japan makes extensive use of debt to improve its returns, because it has an alarmingly high debt to equity ratio of 9.45. Most investors would need a low share price to be interested in a company with low ROE and high debt to equity.

Conclusion

Return on equity is useful for comparing the quality of different businesses. In our books, the highest quality companies have high return on equity, despite low debt. 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.

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. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too.
