Startup Valuation & Equity Dilution Calculator

How Are Startups Valued in 2026?
Startup valuation is an art informed by market comparables, sector demand, and traction velocity. In 2026, venture capital firms have transitioned away from the speculative hype multiples of 2021 toward capital-efficient, high-margin revenue models. Knowing whether to anchor your pitch on ARR multiples, the Berkus Method, or regional angel scorecards gives founders significant leverage during term sheet negotiations.
The Three Core Valuation Methodologies
- SaaS ARR Revenue Multiples: For companies with recurring customer subscriptions, valuation equals
ARR × Multiple. Companies growing >100% year-over-year command premium multiples between 12x and 25x. - The Berkus Method: Perfect for pre-revenue founders. Developed by venture investor Dave Berkus, it assigns up to $500k to each of five risk milestones (Idea, Team, Prototype, Strategic Alliances, Sales Rollout), resulting in pre-money valuations up to $2.5M.
- Pre-Money vs. Post-Money Equity Dilution:
Post-Money = Pre-Money + Investment. The investor's ownership percentage equalsInvestment / Post-Money. Founders typically surrender 10% to 20% equity per funding round.

Frequently Asked Questions
What is a typical equity dilution percentage for a Seed round?
Seed round dilution typically ranges between 15% and 25%. Giving away more than 25% in a seed round can leave founders with insufficient equity for future Series A and B employee option pools.
How does Net Dollar Retention (NDR) impact valuation multiples?
SaaS companies with NDR greater than 115% (meaning existing customers spend more each year even without new customer acquisition) routinely command 30% to 50% higher valuation multiples from venture capital funds.
