## Definition
Post-Money Valuation is the calculated value of a startup immediately after a funding round is completed.

## Architectural Mechanics & Deep Dive
Post-Money Valuation is the value of a startup immediately after a funding round is completed. It is calculated by adding the amount of new capital raised to the pre-money valuation (Post-Money = Pre-Money + Investment Amount). The post-money valuation directly dictates the ownership percentage of the new investors (Ownership % = Investment Amount / Post-Money Valuation). A higher post-money valuation reduces dilution for existing shareholders.
