How Do I Calculate Return On Equity?

The formula for return on equity is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for Advanced Medical Solutions Group:

11% = UK£21m ÷ UK£183m (Based on the trailing twelve months to June 2019.)

It's easy to understand the 'net profit' part of that equation, but 'shareholders' equity' requires further explanation. 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 ROE Signify?

ROE looks at the amount a company earns relative to the money it has kept within the business. 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, as a general rule, a high ROE is a good thing. Clearly, then, one can use ROE to compare different companies.

Does Advanced Medical Solutions Group Have A Good Return On Equity?

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. The image below shows that Advanced Medical Solutions Group has an ROE that is roughly in line with the Medical Equipment industry average (11%).

That isn't amazing, but it is respectable. 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 debt used for growth will improve returns, but won't affect the total equity. That will make the ROE look better than if no debt was used.

Advanced Medical Solutions Group's Debt And Its 11% ROE

Shareholders will be pleased to learn that Advanced Medical Solutions Group has not one iota of net debt! Its ROE suggests it is a decent business; and the fact it is not leveraging returns indicates it is well worth watching. At the end of the day, when a company has zero debt, it is in a better position to take future growth opportunities.

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. 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. It is important to consider other factors, such as future profit growth -- and how much investment is required going forward.
