What Is P/E | Price-to-Earnings Ratio
P/E (Price-to-Earnings Ratio) is one of the most popular stock valuation metrics.
It tells you how much investors are willing to pay for $1 of a company’s earnings.
If a stock has a P/E of 20, investors are paying 20 times the company’s annual earnings per share.
How to calculate P/E ratio
P/E Ratio = Share Price / Earnings Per Share (EPS)
And:
EPS = Net Income / Number of Shares Outstanding
Real-Life P/E Example
If a company’s stock price is $60 and its EPS is $3:
P/E = 60 / 3 = 20
What is a good P/E ratio?

There is no single perfect number, but generally:

A good P/E depends on the industry and company growth.
