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 Mangalore Refinery and Petrochemicals is:

6.7% = ₹8.2b ÷ ₹123b (Based on the trailing twelve months to December 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 ₹0.07 in profit.

Does Mangalore Refinery and Petrochemicals 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. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. If you look at the image below, you can see Mangalore Refinery and Petrochemicals has a lower ROE than the average (14%) in the Oil and Gas industry classification.

That certainly isn't ideal. Although, we think that a lower ROE could still mean that a company has the opportunity to better its returns with the use of leverage, provided its existing debt levels are low. When a company has low ROE but high debt levels, we would be cautious as the risk involved is too high. Our risks dashboard should have the 3 risks we have identified for Mangalore Refinery and Petrochemicals.

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 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 Mangalore Refinery and Petrochemicals' Debt And Its 6.7% Return On Equity

Mangalore Refinery and Petrochemicals does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.10. With a fairly low ROE, and significant use of debt, it's hard to get excited about this business at the moment. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.

Conclusion

Return on equity is one way we can compare its business quality of different companies. A company that can achieve a high return on equity without debt could be considered a high quality business. 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.
