# Should We Worry About WD-40 Company's (NASDAQ:WDFC) P/E Ratio?

Today, we'll introduce the concept of the P/E ratio for those who are learning about investing. We'll apply a basic P/E ratio analysis to WD-40 Company's (NASDAQ:WDFC), to help you decide if the stock is worth further research. WD-40 has a P/E ratio of 36.43, based on the last twelve months. That means that at current prices, buyers pay \$36.43 for every \$1 in trailing yearly profits.

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

The formula for price to earnings is:

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

Or for WD-40:

P/E of 36.43 = \$180.49 Ã· \$4.95 (Based on the year to May 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. All else being equal, it's better to pay a low price -- but as Warren Buffett said, 'It's far better to buy a wonderful company at a fair price than a fair company at a wonderful price.'

### Does WD-40 Have A Relatively High Or Low P/E For Its Industry?

The P/E ratio essentially measures market expectations of a company. As you can see below, WD-40 has a higher P/E than the average company (26.7) in the household products industry.

That means that the market expects WD-40 will outperform other companies in its industry. Shareholders are clearly optimistic, but the future is always uncertain. So further research is always essential. I often monitor director buying and selling.

### How Growth Rates Impact P/E Ratios

Probably the most important factor in determining what P/E a company trades on is the earnings growth. Earnings growth means that in the future the 'E' will be higher. And in that case, the P/E ratio itself will drop rather quickly. Then, a lower P/E should attract more buyers, pushing the share price up.

WD-40 increased earnings per share by an impressive 20% over the last twelve months. And its annual EPS growth rate over 5 years is 13%. With that performance, you might expect an above average P/E ratio.

### 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. 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.

Spending on growth might be good or bad a few years later, but the point is that the P/E ratio does not account for the option (or lack thereof).

### WD-40's Balance Sheet

WD-40 has net debt worth just 2.4% of its market capitalization. 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 WD-40's P/E Ratio

WD-40's P/E is 36.4 which is above average (17.9) in its market. The company is not overly constrained by its modest debt levels, and its recent EPS growth very solid. So on this analysis it seems reasonable that its P/E ratio is above average.
