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 Parker-Hannifin Corporation (NYSE:PH).

Over the last twelve months Parker-Hannifin has recorded a ROE of 24%. One way to conceptualize this, is that for each \$1 of shareholders' equity it has, the company made \$0.24 in profit.

### How Do I Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit Ã· Shareholders' Equity

Or for Parker-Hannifin:

24% = US\$1.5b Ã· US\$6.0b (Based on the trailing twelve months to March 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. Shareholders' equity can be calculated by subtracting the total liabilities of the company from the total assets of the company.

### What Does ROE Mean?

ROE looks at the amount a company earns relative to the money it has kept within the business. The 'return' is the yearly profit. 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 ROE can be used to compare two businesses.

### Does Parker-Hannifin 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. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As you can see in the graphic below, Parker-Hannifin has a higher ROE than the average (14%) in the Machinery industry.

That's clearly a positive. In my book, a high ROE almost always warrants a closer look. For example you might check if insiders are buying shares.

### The Importance Of Debt To Return On Equity

Most companies need money -- from somewhere -- to grow their 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. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

### Combining Parker-Hannifin's Debt And Its 24% Return On Equity

While Parker-Hannifin does have some debt, with debt to equity of just 0.88, we wouldn't say debt is excessive. When I see a high ROE, fuelled by only modest debt, I suspect the business is high quality. 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.

### But It's Just One Metric

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. 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. Profit growth rates, versus the expectations reflected in the price of the stock, are a particularly important to consider.
