Post-Money Valuation
= Pre-Money + Investment
Investor Ownership
= Investment / Post-Money
The Formula
The core mathematical relationship in early-stage venture is simple addition, yet founders often confuse it when dealing with option pools. The baseline rule:
Post-Money = Pre-Money + Investment
Investor % = Investment / Post-MoneyNote: This basic model assumes the option pool is already factored into the Pre-Money valuation. If investors require an option pool expansion before the round closes, the "effective" pre-money valuation drops. See the Option Pool Calculator for the advanced "shuffle" mechanics.
