How it works

  • Post-money = pre-money + raise. Investors own raise ÷ post-money of the company.
  • Share price = pre-money ÷ pre-round shares outstanding (assuming option pool is in pre-money).
  • New shares issued = raise ÷ share price; founder ownership dilutes by raise ÷ post-money.
  • For an ESOP pool top-up included in the round, use our ESOP pool calculator which models the “option pool shuffle”.
