Discounted cash flow
A DCF starts from trailing free cash flow, so it can overstate value if the last 12 months were unusually strong (or weak). Use the bear case or edit the starting cash flow if so.
Edit assumptions · recalculates instantly
Free cash flow = operating cash flow − capital spending, trailing 12 months (TTM to 2026-06-30). Growth default: average of 3-year revenue CAGR and latest revenue growth, capped at 30%. Years 6–10 fade linearly to terminal growth. Discount rate = 4.25% risk-free assumption + beta 1.00 (n/a) × 5% equity premium, kept within 7–13%. Bear: lower growth, +1 pt discount, 2% terminal. Bull: higher growth, −1 pt, 3%.
