This article is for investors who would like to improve their understanding of price to earnings ratios (P/E ratios). To keep it practical, we'll show how Allegion plc's (NYSE:ALLE) P/E ratio could help you assess the value on offer. Allegion has a price to earnings ratio of 23.55, based on the last twelve months. In other words, at today's prices, investors are paying \$23.55 for every \$1 in prior year profit.

### How Do You Calculate Allegion's P/E Ratio?

The formula for price to earnings is:

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

Or for Allegion:

P/E of 23.55 = \$109.98 Ã· \$4.67 (Based on the year to March 2019.)

### Is A High P/E 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 is not a good or a bad thing per se, but a high P/E does imply buyers are optimistic about the future.

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

The P/E ratio indicates whether the market has higher or lower expectations of a company. You can see in the image below that the average P/E (18.4) for companies in the building industry is lower than Allegion's P/E.

Allegion's P/E tells us that market participants think the company will perform better than its industry peers, going forward. Clearly the market expects growth, but it isn't guaranteed. So further research is always essential. I often monitor director buying and selling.

### 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. If earnings are growing quickly, then the 'E' in the equation will increase faster than it would otherwise. Therefore, even if you pay a high multiple of earnings now, that multiple will become lower in the future. Then, a lower P/E should attract more buyers, pushing the share price up.

Allegion's 60% EPS improvement over the last year was like bamboo growth after rain; rapid and impressive. The sweetener is that the annual five year growth rate of 69% is also impressive. With that kind of growth rate we would generally expect a high P/E ratio.

### 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. Thus, the metric does not reflect cash or debt held by the company. Theoretically, a business can improve its earnings (and produce a lower P/E in the future) by investing in growth. That means taking on debt (or spending its cash).

Such spending might be good or bad, overall, but the key point here is that you need to look at debt to understand the P/E ratio in context.

### Is Debt Impacting Allegion's P/E?

Net debt totals 12% of Allegion's market cap. This could bring some additional risk, and reduce the number of investment options for management; worth remembering if you compare its P/E to businesses without debt.

### The Verdict On Allegion's P/E Ratio

Allegion's P/E is 23.6 which is above average (18.1) in its market. While the company does use modest debt, its recent earnings growth is superb. So to be frank we are not surprised it has a high P/E ratio.
