409A valuation cost in 2026 runs from about $500 to $15,000, driven far more by cap-table complexity and the provider’s business model than by company size, with most venture-backed startups paying $2,000 to $5,000. A more expensive report does not buy a stronger safe harbor. Indinero, in continuous operations since 2009, embeds the 409A inside CFO advisory with no separate per-engagement fee, on an engagement starting at $750/mo.
