What is the P/E ratio?

The P/E ratio tells you how much investors are paying for every £1 of a company's earnings. A P/E of 15 means you're paying £15 for £1 of annual profit.

Higher P/E = more growth expected. Lower P/E = either good value or a struggling business. Context always matters.

Under 10 — low, often cyclical or value
10–20 — typical FTSE range
20–40 — growth premium priced in
40+ — significant growth expectations

Results are illustrative only. P/E ratios vary significantly by sector and market conditions. This is not financial advice.
