The method
How it is worked out
- post-money stake
- Share the round's investors own after closing
- pool top-up
- Option pool restored to a target before the round
Simulate up to three funding rounds with option-pool top-ups and see what founders, employees and each investor own at the end. The result updates as you type so you can compare scenarios quickly.
The method
Keep in mind
Use the calculator to compare scenarios rather than as a guaranteed forecast.
Simulate up to three funding rounds with option-pool top-ups and see what founders, employees and each investor group own at the end, and what founders would take at an exit.
Each round dilutes every existing holder by the new investor's post-money stake. Where the option pool is topped up before the round, the top-up is taken from existing holders first. Founder payout at exit is the exit value times final founder ownership.
Founders at 85% with a 15% pool sell 20% at seed (pool to 12%), 20% at Series A (pool to 10%) and 15% at Series B, ending at 46%. At a £100m exit that is £46m before preferences.

Forgetting the pool top-up the investor requires before the round. Assuming a higher valuation always means less dilution overall. Ignoring liquidation preferences when estimating the exit payout.
No. Use the result as a practical check or planning aid and verify important decisions with the relevant primary source, provider or professional advice.
