Pre-money valuation is what a company is worth before new investment comes in, post-money is what it is worth immediately after. The difference determines exactly how much ownership the new investor receives.

Post-money, Formula:

Pre-money valuation plus amount invested

Pre-money, Used to calculate:

Post-money, Used to calculate:

The investor's exact ownership percentage

Post-money, Common founder mistake:
