Your current ownership breakdown and key metrics
Equity dilution happens when you issue new shares and existing ownership percentages decrease. Your slice of the pie gets thinner, but the pie itself is growing more valuable.
For startups, dilution typically happens during funding rounds, SAFE conversions, option pool creation, and convertible note conversions.
Enter your current cap table (authorized shares, issued shares by stakeholder), SAFE details (investment amount, valuation cap, pre/post-money), new round terms (raise amount, pre-money valuation), and option pool size. The calculator outputs your fully diluted cap table with exact ownership percentages after the round closes.
Post-money SAFEs convert to a fixed percentage tied to the valuation cap. Pre-money SAFEs depend on actual round terms, creating more variability. Running these scenarios before you negotiate prevents cap table surprises when the term sheet arrives.
Seed rounds typically dilute founders 15-25%. Series A adds another 20-30%. By Series B, median combined founder ownership sits around 25-30%. Option pools usually run 10-15% at formation with 5-10% refreshes each round.
Dilution isn't always bad—it usually means you're building a team to help your shares actually mean something.
