### How Do I Calculate Advance Auto Parts's Price To Earnings Ratio?

The formula for price to earnings is:

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

P/E of 30.75 = \$176.78 Ã· \$5.75 (Based on the year to December 2018.)

### 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.'

### 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. So while a stock may look expensive based on past earnings, it could be cheap based on future earnings.

Advance Auto Parts shrunk earnings per share by 10% over the last year. But it has grown its earnings per share by 2.1% per year over the last three years.

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

Don't forget that the P/E ratio considers market capitalization. That means it doesn't take debt or cash into account. In theory, a company can lower its future P/E ratio by using cash or debt to invest in growth.

Such expenditure might be good or bad, in the long term, but the point here is that the balance sheet is not reflected by this ratio.

### Is Debt Impacting Advance Auto Parts's P/E?

Advance Auto Parts has net debt worth just 1.2% of its market capitalization. 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.
