Summary

Enter a stock price and EPS to instantly calculate the P/E ratio and see whether the valuation leans value or growth.

How it works

  1. Enter the current market price per share.
  2. Enter the earnings per share (EPS) — use trailing twelve months for a standard P/E.
  3. The calculator divides price by EPS to produce the P/E ratio.
  4. Review the classification: low P/E suggests value, high P/E suggests growth expectations.
  5. Use the earnings yield (inverse of P/E) to compare against bond rates.

Use cases

  • Quickly assess whether a stock looks cheap or expensive relative to its earnings.
  • Compare P/E ratios across multiple stocks in the same sector.
  • Cross-check analyst-reported P/E figures for accuracy.
  • Calculate forward P/E by entering the projected EPS instead of reported EPS.
  • Teach students the relationship between price, earnings, and market expectations.
  • Screen stocks by entering target P/E thresholds to back into a fair price.
