To keep the lesson grounded in practicality, we'll use ROE to better understand Power Grid Corporation of India Limited (NSE:POWERGRID).

How Do You Calculate ROE?

The formula for ROE is:

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

Or for Power Grid Corporation of India:

17% = ₹105b ÷ ₹625b (Based on the trailing twelve months to September 2019.)

Most know that net profit is the total earnings after all expenses, but the concept of shareholders' equity is a little more complicated. It is all earnings retained by the company, plus any capital paid in by shareholders. Shareholders' equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.

What Does ROE Mean?

Return on Equity measures a company's profitability against the profit it has kept for the business (plus any capital injections). The 'return' is the amount earned after tax over the last twelve months. A higher profit will lead to a higher ROE. So, all else being equal, a high ROE is better than a low one. Clearly, then, one can use ROE to compare different companies.

Does Power Grid Corporation of India Have A Good Return On Equity?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As you can see in the graphic below, Power Grid Corporation of India has a higher ROE than the average (13%) in the Electric Utilities industry.

That is a good sign. We think a high ROE, alone, is usually enough to justify further research into a company. For example, I often check if insiders have been buying shares.

How Does Debt Impact ROE?

Companies usually need to invest money to grow their 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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

Power Grid Corporation of India's Debt And Its 17% ROE

Power Grid Corporation of India clearly uses a significant amount of debt to boost returns, as it has a debt to equity ratio of 2.25. while its ROE is respectable, it is worth keeping in mind that there is usually a limit to how much debt a company can use. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.

But It's Just One Metric

Return on equity is one way we can compare the business quality of different companies. Companies that can achieve high returns on equity without too much debt are generally of good quality. All else being equal, a higher ROE is better.

But when a business is high quality, the market often bids it up to a price that reflects this. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
