P/E & simple DCF calculator

Check a stock's P/E ratio and earnings yield, then estimate value per share with a simple two-stage discounted cash flow model.

1. P/E and earnings yield

2. Simple DCF

The terminal growth rate must be lower than the discount rate. Small changes in either one change the answer a lot.

The math

P/E = price ÷ EPS · Earnings yield = EPS ÷ price · PEG = P/E ÷ growth %

Value = Σ FCFt ÷ (1+r)t + [FCF10 × (1+g) ÷ (r − g)] ÷ (1+r)10

A DCF is only as good as its inputs. Use it to ask "what would have to be true for today's price to make sense?" rather than to find a precise number. See Discounted cash flow, explained.
