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