Simply Wall St

While some investors are already well versed in financial metrics (hat tip), this article is for those who would like to learn about Return On Equity (ROE) and why it is important. To keep the lesson grounded in practicality, we'll use ROE to better understand General Dynamics Corporation (NYSE:GD).

General Dynamics has a ROE of 26%, based on the last twelve months. One way to conceptualize this, is that for each $1 of shareholders' equity it has, the company made $0.26 in profit.

How Do I Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders' Equity

Or for General Dynamics:

26% = US$3.3b ÷ US$13b (Based on the trailing twelve months to June 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 all earnings retained by the company, plus any capital paid in by shareholders. You can calculate shareholders' equity by subtracting the company's total liabilities from its total assets.

What Does ROE Signify?

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. Clearly, then, one can use ROE to compare different companies.

Does General Dynamics 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. Pleasingly, General Dynamics has a superior ROE than the average (14%) company in the Aerospace & Defense industry.

That's what I like to see. I usually take a closer look when a company has a better ROE than industry peers. For example, I often check if insiders have been buying shares .

How Does Debt Impact ROE?

Most companies need money -- from somewhere -- to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the case of the first and second options, the ROE will reflect this use of cash, for growth. 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 General Dynamics's Debt And Its 26% Return On Equity

It's worth noting the significant use of debt by General Dynamics, leading to its debt to equity ratio of 1.08. There's no doubt its ROE is impressive, but the company appears to use its debt to boost that metric. Investors should think carefully about how a company might perform if it was unable to borrow so easily, because credit markets do change over time.

The Bottom Line On ROE

Return on equity is useful for comparing the quality of different businesses. 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.

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. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
