Calculation method
Illustrative post-money value = pre-money value + new investment. New investor percentage = new investment / post-money value. The entered current-holder percentage is then multiplied by the percentage retained by existing holders.
Worked example
At a USD 4,000,000 pre-money value with USD 1,000,000 of new investment, the simple post-money value is USD 5,000,000 and the new investor percentage is 20%. A holder entered at 60% becomes 48% before any other cap-table changes.
What the result excludes
