Dilution calculator
Every round costs you a piece of the company. This calculator shows what you keep after three rounds so you can decide how much to raise and at what price.

How the calculation works
New investors in each round own the amount raised divided by the post-money valuation. If you set an option pool target, new pool shares are issued before the round, inside the pre-money, so only existing holders are diluted. A round with a zero valuation or a zero amount is skipped, and pool targets are capped at 50%.
The value of what you own matters more than the percentage. A smaller slice of a much bigger company can be worth far more. Know your numbers before an investor quotes them to you.
