### 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 Mueller Water Products:

P/E of 14.4 = \$9.61 ÷ \$0.67 (Based on the trailing twelve months to September 2018.)

### 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 Growth Rates Impact P/E Ratios

Earnings growth rates have a big influence on P/E ratios. That’s because companies that grow earnings per share quickly will rapidly increase the ‘E’ in the equation. That means unless the share price increases, the P/E will reduce in a few years. Then, a lower P/E should attract more buyers, pushing the share price up.

Notably, Mueller Water Products grew EPS by a whopping 97% in the last year. And earnings per share have improved by 22% annually, over the last five years. I’d therefore be a little surprised if its P/E ratio was not relatively high.

### How Does Mueller Water Products’s P/E Ratio Compare To Its Peers?

The P/E ratio essentially measures market expectations of a company. If you look at the image below, you can see Mueller Water Products has a lower P/E than the average (18.6) in the machinery industry classification.

Mueller Water Products’s P/E tells us that market participants think it will not fare as well as its peers in the same industry. Many investors like to buy stocks when the market is pessimistic about their prospects. It is arguably worth checking if insiders are buying shares, because that might imply they believe the stock is undervalued.

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

It’s important to note that the P/E ratio considers the market capitalization, not the enterprise value. That means it doesn’t take debt or cash into account. Hypothetically, a company could reduce its future P/E ratio by spending its cash (or taking on debt) to achieve higher earnings.

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.

### How Does Mueller Water Products’s Debt Impact Its P/E Ratio?

Mueller Water Products’s net debt is 6.5% of its market cap. So it doesn’t have as many options as it would with net cash, but its debt would not have much of an impact on its P/E ratio.

### The Verdict On Mueller Water Products’s P/E Ratio

Mueller Water Products has a P/E of 14.4. That’s below the average in the US market, which is 16.7. The company does have a little debt, and EPS growth was good last year. If it continues to grow, then the current low P/E may prove to be unjustified.

Investors should be looking to buy stocks that the market is wrong about. If the reality for a company is not as bad as the P/E ratio indicates, then the share price should increase as the market realizes this.
