# A Closer Look At Severn Trent Plc's (LON:SVT) Impressive ROE

Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). We'll use ROE to examine Severn Trent Plc (LON:SVT), by way of a worked example.

Over the last twelve months Severn Trent has recorded a ROE of 24%. That means that for every Â£1 worth of shareholders' equity, it generated Â£0.24 in profit.

### How Do I Calculate ROE?

The formula for ROE is:

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

Or for Severn Trent:

24% = UKÂ£297m Ã· UKÂ£1.2b (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 the capital paid in by shareholders, plus any retained earnings. You can calculate shareholders' equity by subtracting the company's total liabilities from its total assets.

### What Does Return On Equity Signify?

ROE looks at the amount a company earns relative to the money it has kept within the business. The 'return' is the profit over the last twelve months. That means that the higher the ROE, the more profitable the company is. So, all else equal, investors should like a high ROE. That means it can be interesting to compare the ROE of different companies.

### Does Severn Trent Have A Good ROE?

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. Pleasingly, Severn Trent has a superior ROE than the average (8.9%) company in the Water Utilities industry.

That is a good sign. I usually take a closer look when a company has a better ROE than industry peers. For example you might check if insiders are buying shares.

### Why You Should Consider Debt When Looking At 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 two cases, the ROE will capture this use of capital to grow. 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.

### Combining Severn Trent's Debt And Its 24% Return On Equity

It appears that Severn Trent makes extensive use of debt to improve its returns, because it has a relatively high debt to equity ratio of 5.02. Its ROE is clearly quite good, but it would probably be significantly lower without all the debt.

### The Key Takeaway

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. In my book the highest quality companies have high return on equity, despite low debt. 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. 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.
