What it does
The ESOP Calculator models employee equity from the founder’s side and the employee’s side at once. Inputs: your cap table, options pool, dilution roadmap, vesting schedule. Outputs: what a grant is worth today, what it’s worth at exit at multiple valuations, what dilution does to it across rounds, and what the tax treatment looks like in the relevant jurisdiction.
Who it’s for
Founders designing equity grants. Operators evaluating offers. Heads of People setting equity bands. Anyone who has tried to answer “what’s this worth?” and realized the answer depends on six assumptions nobody wrote down.
How to use it
Enter your cap table, options pool size, planned dilution across future rounds, exit valuation range, and the grant you want to model. The calculator shows the grant’s value at each stage, the dilution impact, the vesting outcome at common departure points, and the tax-adjusted take-home at exit.
Why this exists
Every offer letter has a number on it that means something different to the person signing it than to the person writing it. Most equity conversations happen across that gap. This calculator closes it: founders see what they’re actually granting, operators see what they’re actually getting.
