### How Do You Calculate Waste Management’s P/E Ratio?

The formula for P/E is:

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

Or for Waste Management:

P/E of 17.48 = \$93.11 ÷ \$5.33 (Based on the year to September 2018.)

### 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. 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.

Notably, Waste Management grew EPS by a whopping 70% in the last year. And it has bolstered its earnings per share by 34% per year over the last five years. So we’d generally expect it to have a relatively high P/E ratio.

Waste Management’s P/E tells us that market participants think its prospects are roughly in line with its industry. The company could surprise by performing better than average, in the future. Further research into factors such asmanagement tenure, could help you form your own view on whether that is likely.

### Remember: P/E Ratios Don’t Consider The Balance Sheet

Don’t forget that the P/E ratio considers market capitalization. Thus, the metric does not reflect cash or debt held by the company. 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).
