Pro rata: the money to keep your percentage
An investor owns part of the company before a new round. See what it owns if it buys nothing, if it buys its pro rata, and what it must buy to stay level.
Fully diluted.

Investor's ownership after the round
- Buys nothing
- 8%
- Buys its pro rata
- 10%
- Buys 2x pro rata
- 12%
The investor owns 10% before the round. The new money buys 20% of the company ($20M ÷ $100M). If the investor buys nothing, it goes to 8%.
Its pro rata amount is 10% × $20M = $2M. That buys exactly its part of the new shares, so it stays at 10%.
