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

The formula for price to earnings is:

Price to Earnings Ratio = Price per Share ÷ Earnings per Share (EPS)

Or for Jack in the Box:

P/E of 17.89 = \$81.95 ÷ \$4.58 (Based on the year to April 2019.)

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

A higher P/E ratio implies that investors pay a higher price for the earning power of the business. That isn’t a good or a bad thing on its own, but a high P/E means that buyers have a higher opinion of the business’s prospects, relative to stocks with a lower P/E.

### How Growth Rates Impact P/E Ratios

Generally speaking the rate of earnings growth has a profound impact on a company’s P/E multiple. When earnings grow, the ‘E’ increases, over time. That means unless the share price increases, the P/E will reduce in a few years. A lower P/E should indicate the stock is cheap relative to others — and that may attract buyers.

Jack in the Box increased earnings per share by a whopping 34% last year. And its annual EPS growth rate over 5 years is 16%. So we’d generally expect it to have a relatively high P/E ratio.

### Does Jack in the Box Have A Relatively High Or Low P/E For Its Industry?

One good way to get a quick read on what market participants expect of a company is to look at its P/E ratio. We can see in the image below that the average P/E (23.1) for companies in the hospitality industry is higher than Jack in the Box’s P/E.

This suggests that market participants think Jack in the Box will underperform other companies in its industry. While current expectations are low, the stock could be undervalued if the situation is better than the market assumes. If you consider the stock interesting, further research is recommended. For example, I often monitor director buying and selling.

### A Limitation: P/E Ratios Ignore Debt and Cash In The Bank

One drawback of using a P/E ratio is that it considers market capitalization, but not the balance sheet. In other words, it does not consider any debt or cash that the company may have on the balance sheet. In theory, a company can lower its future P/E ratio by using cash or debt to invest in growth.

While growth expenditure doesn’t always pay off, the point is that it is a good option to have; but one that the P/E ratio ignores.

### Jack in the Box’s Balance Sheet

Net debt is 50% of Jack in the Box’s market cap. You’d want to be aware of this fact, but it doesn’t bother us.
