FAQ
What is the difference between pre-money and post-money valuation?
Pre-money is the value of the company before the new investment; post-money is pre-money plus the new money. The investor's stake is always calculated on the post-money value.
How do I calculate post-money valuation?
Add the investment to the pre-money valuation. €4,000,000 pre-money plus a €1,000,000 investment gives €5,000,000 post-money, so the investor owns 20%.
What valuation does “€500,000 for 10%” imply?
The post-money is €500,000 ÷ 10% = €5,000,000, so the pre-money valuation is €4,500,000. Switch the calculator to the second mode to work this out for any offer.
How is the price per share calculated?
Price per share is the pre-money valuation divided by the fully diluted shares before the round. New shares issued equal the investment divided by that price.
