P/E ratio formulas

P/E = Share price ÷ Earnings per share (EPS)

Trailing P/E = Price ÷ Last 12 months EPS

Forward P/E = Price ÷ Next 12 months consensus EPS estimate

PEG ratio = P/E ÷ Expected earnings growth rate %

Worked example: Share price 45. Trailing EPS 2.25. Trailing P/E = 45/2.25 = 20×. Forward EPS estimate 2.70. Forward P/E = 45/2.70 = 16.7×. Expected growth rate 15%. PEG = 16.7/15 = 1.11 — modestly valued relative to growth rate.
