You pay 500 for 20/yr earnings — 25.0 years of current profits to recoup, assuming no growth.

What is the P/E Ratio?

The Price-to-Earnings (P/E) ratio tells you how many years of a company's current earnings you're paying for with one share.

A P/E of 20 means you're paying 20x this year's earnings. If nothing changes, it would take 20 years to "earn back" the purchase price — so lower is generally cheaper.

The Formula

P/E = Stock Price ÷ EPS

EPS = Earnings Per Share = Net Profit ÷ Total Shares

Important caveats

  • Compare P/E within the same sector — not across sectors.
  • High-growth companies often deserve higher P/E multiples.
  • P/E is meaningless for loss-making companies (negative EPS).
  • Always pair P/E with PEG ratio and balance sheet health.
