How Do I Calculate A Price To Earnings Ratio?
The formula for P/E is:
Price to Earnings Ratio = Price per Share ÷ Earnings per Share (EPS)
Or for G N A Axles:
P/E of 8.62 = ₹264.4 ÷ ₹30.67 (Based on the trailing twelve months to March 2019.)
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. 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
P/E ratios primarily reflect market expectations around earnings growth rates. 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. A lower P/E should indicate the stock is cheap relative to others -- and that may attract buyers.
Notably, G N A Axles grew EPS by a whopping 29% in the last year. And earnings per share have improved by 29% annually, over the last five years. So we'd generally expect it to have a relatively high P/E ratio.

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. In theory, a company can lower its future P/E ratio by using cash or debt to invest in growth.
