3 toolsestimate_409a_valueEstimate 409A common stock valueRead-onlyIdempotentInspect
Gives an indicative range for the fair market value per share of a US private company's common stock, as a planning estimate before a formal 409A valuation (for example, to anticipate an option strike price). Uses an option pricing model backsolve when there is a priced round in the last 12 months; otherwise a rolled-forward round, a sector revenue multiple, or an asset-based approach, depending on the inputs. Applies Finnerty and Chaffe marketability discounts. Inputs are numbers from the cap table and financials; no company or personal names are needed. Limitations: treats all preferred as non-participating and pari passu with 1:1 conversion, and does not model SAFEs or convertible notes. The result is not a 409A valuation.
