How Do You Calculate A P/E Ratio?

The formula for price to earnings is:

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

Or for WD-40:

P/E of 33.96 = $163 ÷ $4.8 (Based on the year to February 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. 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.'

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. That means even if the current P/E is high, it will reduce over time if the share price stays flat. And as that P/E ratio drops, the company will look cheap, unless its share price increases.

WD-40 increased earnings per share by an impressive 20% over the last twelve months. And it has bolstered its earnings per share by 13% per year over the last five years. So one might expect an above average P/E ratio.

How Does WD-40's P/E Ratio Compare To Its Peers?

The P/E ratio indicates whether the market has higher or lower expectations of a company. As you can see below, WD-40 has a higher P/E than the average company (24.4) in the household products industry.

That means that the market expects WD-40 will outperform other companies in its industry. Clearly the market expects growth, but it isn't guaranteed. So investors should always consider the P/E ratio alongside other factors, such as whether company directors have been buying shares.

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

It's important to note that the P/E ratio considers the market capitalization, not the enterprise value. Thus, the metric does not reflect cash or debt held by the company. 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.

Is Debt Impacting WD-40's P/E?

Net debt totals just 2.6% of WD-40's market cap. The market might award it a higher P/E ratio if it had net cash, but its unlikely this low level of net borrowing is having a big impact on the P/E multiple.

The Verdict On WD-40's P/E Ratio

WD-40 trades on a P/E ratio of 34, which is above the US market average of 17.7. While the company does use modest debt, its recent earnings growth is very good. So on this analysis it seems reasonable that its P/E ratio is above average.
