### How Do I Calculate A Price To Earnings Ratio?

The formula for price to earnings is:

Price to Earnings Ratio = Price per Share Ã· Earnings per Share (EPS)

Or for Greenbrier Companies:

P/E of 14.02 = \$30.56 Ã· \$2.18 (Based on the year to August 2019.)

### Is A High Price-to-Earnings Ratio Good?

A higher P/E ratio means that buyers have to pay a higher price for each \$1 the company has earned over the last year. That isn't necessarily good or bad, but a high P/E implies relatively high expectations of what a company can achieve in the future.

### How Does Greenbrier Companies's P/E Ratio Compare To Its Peers?

One good way to get a quick read on what market participants expect of a company is to look at its P/E ratio. The image below shows that Greenbrier Companies has a lower P/E than the average (21.5) P/E for companies in the machinery industry.

Its relatively low P/E ratio indicates that Greenbrier Companies shareholders think it will struggle to do as well as other companies in its industry classification. Since the market seems unimpressed with Greenbrier Companies, it's quite possible it could surprise on the upside. You should delve deeper. I like to check if company insiders have been buying or selling.

### How Growth Rates Impact P/E Ratios

Companies that shrink earnings per share quickly will rapidly decrease the 'E' in the equation. That means unless the share price falls, the P/E will increase in a few years. So while a stock may look cheap based on past earnings, it could be expensive based on future earnings.

Greenbrier Companies's earnings per share fell by 56% in the last twelve months. And over the longer term (5 years) earnings per share have decreased 11% annually. This could justify a pessimistic P/E.

### Don't Forget: The P/E Does Not Account For Debt or Bank Deposits

The 'Price' in P/E reflects the market capitalization of the company. So it won't reflect the advantage of cash, or disadvantage of debt. The exact same company would hypothetically deserve a higher P/E ratio if it had a strong balance sheet, than if it had a weak one with lots of debt, because a cashed up company can spend on growth.

Such expenditure might be good or bad, in the long term, but the point here is that the balance sheet is not reflected by this ratio.

### Greenbrier Companies's Balance Sheet

Greenbrier Companies's net debt is 52% of its market cap. This is a reasonably significant level of debt -- all else being equal you'd expect a much lower P/E than if it had net cash.

### The Verdict On Greenbrier Companies's P/E Ratio

Greenbrier Companies's P/E is 14.0 which is below average (17.9) in the US market. Given meaningful debt, and a lack of recent growth, the market looks to be extrapolating this recent performance; reflecting low expectations for the future.
