Transparent method
How this calculation works
Granted options are multiplied by vested percentage. Positive share-value minus strike-price spread is applied to vested options.
Useful output
What you receive
Gross vested spread, vested options, exercise cost, spread per option, assumptions, and CSV.
Decision guardrail
What this does not decide
Private-company shares may be illiquid and valuations can change. Gross spread is not cash value or after-tax proceeds.
Practical uses
Where this tool helps
