The Anti-dilution Calculator
View how a down round affects your cap table

The following calculator shows the impact of anti-dilution on your cap table in multiple scenarios. For simplicity, it is assumed that the company has an up round followed by a down round.
- Incorporation round shows the total number of shares and the share price at incorporation of the company.
- Seed Round is your first round with a higher share price thereby becoming an up round.
- Series A round is your down round where a new investor is offering investment at a lower valuation than the Seed round.
In this example, we will look at the impact of anti-dilution on Seed Round investors.
