Results
Post-money = Pre-money + Investment. With equity %: Post-money = Investment ÷ Equity %. Price per share = Post-money ÷ Total shares after round.
What these mean
Pre-money is valuation before new money; post-money is after. Equity % sold = Investment ÷ Post-money. Use for cap table and term sheet maths.
How to calculate
From investment + equity %: Post-money = Investment ÷ Equity %. Pre-money = Post-money − Investment. From pre-money + investment: Post-money = Pre-money + Investment; Equity % = Investment ÷ Post-money.
How to improve
Negotiate on pre-money to retain more ownership for the same investment. Improve traction and metrics to justify higher pre-money.
Common mistakes
Confusing pre and post; using fully diluted vs issued shares inconsistently; or forgetting option pool expansion in effective dilution.
How to interpret
Compare pre-money to recent rounds and benchmarks. Post-money sets the new baseline for the next round and for option pricing.
