About
You got an offer with X options at a Y strike — but what is that actually worth? This tool models your equity across realistic outcomes: the company fails, gets acquihired, has a modest exit, a strong exit, or becomes a unicorn. It accounts for future dilution, your strike price, and a rough capital-gains haircut so you can decide whether the equity portion is meaningful or marketing.
How it works
- 01Enter the number of options or RSUs granted and your strike price (0 for RSUs).
- 02Enter the company's current post-money valuation and fully-diluted shares — or just paste the % ownership.
- 03Set expected future dilution from rounds before exit (typical: 10–20% per round).
- 04We multiply your final ownership by each scenario valuation, subtract your strike cost, and apply a flat long-term capital gains haircut.
Examples
Series A engineer, 0.1%
0.1% at a $50M company, 40% dilution before exit → 0.06% final. At a $1B exit that's $600k pre-tax, ~$450k after LTCG — but the probability-weighted expected value is closer to $40–80k.
Seed hire, 0.5%
0.5% at a $10M seed, 50% dilution → 0.25% final. Failure at 60% probability drags the expected value down to ~$25–60k depending on upside scenarios.
