How dilution is calculated

Investor ownership = investment ÷ post-money valuation. Existing ownership percentages are multiplied by the portion retained by existing shareholders. Share counts assume the round price equals pre-money valuation divided by existing fully diluted shares.

This simplified estimate excludes option-pool top-ups, convertible instruments, liquidation preferences and transaction costs. Use final legal documents for an actual round.
