How Do I Calculate ROE?
The formula for ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
Or for National Grid:
7.7% = UK£1.5b ÷ UK£19b (Based on the trailing twelve months to September 2019.)
Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. It is the capital paid in by shareholders, plus any retained earnings. The easiest way to calculate shareholders' equity is to subtract the company's total liabilities from the total assets.
What Does Return On Equity 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. The higher the ROE, the more profit the company is making. So, all else being equal, a high ROE is better than a low one. That means ROE can be used to compare two businesses.
Does National Grid Have A Good Return On Equity?
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. The image below shows that National Grid has an ROE that is roughly in line with the Integrated Utilities industry average (7.8%).
That's not overly surprising. ROE tells us about the quality of the business, but it does not give us much of an idea if the share price is cheap. For those who like to find winning investments this free list of growing companies with recent insider purchasing, could be just the ticket.
How Does Debt Impact Return On Equity?
Most companies need money -- from somewhere -- 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. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.
National Grid's Debt And Its 7.7% ROE
National Grid clearly uses a significant amount of debt to boost returns, as it has a debt to equity ratio of 1.71. While the ROE isn't too bad, it would probably be a lot lower if the company was forced to reduce debt. Debt increases risk and reduces options for the company in the future, so you generally want to see some good returns from using it.
The Key Takeaway
Return on equity is useful for comparing the quality of different businesses. In my book 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.
But when a business is high quality, the market often bids it up to a price that reflects this. 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.
