How to Calculate and Understand the P/E Ratio

The Price-to-Earnings (P/E) Ratio is one of the most widely used valuation multiples in fundamental equity analysis. It allows investors to quickly gauge whether a stock is trading at a premium or discount relative to its earnings power and sector peers.

Calculate any company's valuation multiple using the Burnjet P/E Ratio Calculator.


The P/E Ratio Formula #

P/E Ratio=Market Price Per ShareEarnings Per Share (EPS)\text{P/E Ratio} = \frac{\text{Market Price Per Share}}{\text{Earnings Per Share (EPS)}}

Where:

  • Market Price Per Share: Current traded stock price
  • Earnings Per Share (EPS): Net Net Income/Total Diluted Shares Outstanding\text{Net Net Income} / \text{Total Diluted Shares Outstanding}

Step-by-Step: Using the Burnjet P/E Ratio Calculator #
