One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. We’ll use ROE to examine Railcare Group AB (publ) (STO:RAIL), by way of a worked example.

Railcare Group has a ROE of 2.3%, based on the last twelve months. That means that for every SEK1 worth of shareholders’ equity, it generated SEK0.023 in profit.

### How Do I Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders’ Equity

Or for Railcare Group:

2.3% = 3.006 ÷ kr129m (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 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?

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. That means that the higher the ROE, the more profitable the company is. So, as a general rule, a high ROE is a good thing. That means it can be interesting to compare the ROE of different companies.

### Does Railcare Group 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. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As is clear from the image below, Railcare Group has a lower ROE than the average (12%) in the Infrastructure industry.

That’s not what we like to see. We’d prefer see an ROE above the industry average, but it might not matter if the company is undervalued. Nonetheless, it might be wise to check if insiders have been selling.

### How Does Debt Impact Return On Equity?

Most companies need money — from somewhere — to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. 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.

### Combining Railcare Group’s Debt And Its 2.3% Return On Equity

Railcare Group clearly uses a significant amount debt to boost returns, as it has a debt to equity ratio of 1.57. Its ROE is quite low, even with the use of significant debt; that’s not a good result, in my opinion. Debt does bring extra risk, so it’s only really worthwhile when a company generates some decent returns from it.

### The Key Takeaway

Return on equity is one way we can compare the business quality of different companies. 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.

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. It is important to consider other factors, such as future profit growth — and how much investment is required going forward. So I think it may be worth checking this free report on analyst forecasts for the company.

But note: Railcare Group may not be the best stock to buy. So take a peek at this free list of interesting companies with high ROE and low debt.
