### How Do I Calculate ROE?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders’ Equity

Or for Sterling Construction Company:

16% = 22.66 ÷ US\$170m (Based on the trailing twelve months to September 2018.)

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 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 Signify?

ROE looks at the amount a company earns relative to the money it has kept within the business. The ‘return’ is the yearly profit. 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 Sterling Construction Company Have A Good ROE?

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. Pleasingly, Sterling Construction Company has a superior ROE than the average (13%) company in the Construction industry.

That is a good sign. We think a high ROE, alone, is usually enough to justify further research into a company. One data point to check is if insiders have bought shares recently.

### The Importance Of Debt To Return On Equity

Companies usually need to invest money to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the first two cases, the ROE will capture this use of capital to grow. 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.

### Sterling Construction Company’s Debt And Its 16% ROE

While Sterling Construction Company does have some debt, with debt to equity of just 0.48, we wouldn’t say debt is excessive. The fact that it achieved a fairly good ROE with only modest debt suggests the business might be worth putting on your watchlist. Careful use of debt to boost returns is often very good for shareholders. However, it could reduce the company’s ability to take advantage of future opportunities.

### In Summary

Return on equity is useful for comparing the quality of different businesses. A company that can achieve a high return on equity without debt could be considered a high quality business. All else being equal, a higher ROE is better.

But ROE is just one piece of a bigger puzzle, since high quality businesses often trade on high multiples of earnings. 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.
