How Do You Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit ÷ Shareholders’ Equity

Or for Aggregated Micro Power Holdings:

5.7% = UK£793k ÷ UK£14m (Based on the trailing twelve months to September 2018.)

Most readers would understand what net profit is, but it’s worth explaining the concept of shareholders’ equity. It is all earnings retained by the company, plus any capital paid in by shareholders. The easiest way to calculate shareholders’ equity is to subtract the company’s total liabilities from the total assets.

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 profit over the last twelve months. The higher the ROE, the more profit the company is making. So, all else equal, investors should like a high ROE. That means it can be interesting to compare the ROE of different companies.

Does Aggregated Micro Power Holdings 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. 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 Aggregated Micro Power Holdings has an ROE that is roughly in line with the Renewable Energy industry average (5.7%).

That’s not overly surprising. ROE can give us a view about company quality, but many investors also look to other factors, such as whether there are insiders buying shares. If you are like me, then you will not want to miss this free list of growing companies that insiders are buying.

How Does Debt Impact ROE?

Virtually all companies need money to invest in the business, to grow profits. That cash can come from issuing shares, retained earnings, 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.

Combining Aggregated Micro Power Holdings’s Debt And Its 5.7% Return On Equity

Although Aggregated Micro Power Holdings does use debt, its debt to equity ratio of 0.78 is still low. Its ROE isn’t particularly impressive, but the debt levels are quite modest, so the business probably has some real potential. Conservative use of debt to boost returns is usually a good move for shareholders, though it does leave the company more exposed to interest rate rises.

The Key Takeaway

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. If two companies have the same ROE, then I would generally prefer the one with less debt.

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. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
