About

Translate a startup equity offer into a probability-weighted dollar value. Set your ownership %, expected dilution, and a distribution over outcomes — see expected value across scenarios.

How it works

  1. 01Final ownership = current ownership × (1 − future dilution%).
  2. 02Expected $ = final ownership × Σ (probability × outcome valuation).
  3. 03Adjust probabilities to match the company's stage realism — most early-stage startups fail or modest-exit.

Examples

Series A engineer

0.25% ownership, 50% future dilution → 0.125% at exit. Weighted across {modest $50M, base $250M, strong $1B, unicorn $10B} = a few hundred thousand expected.

Seed founder

20% ownership, 60% future dilution → 8%. Same scenario distribution = $5M+ expected, with massive variance.

FAQ

What probabilities are realistic?+
Industry data: ~70% of seed startups fail (return < cost). ~20% return 1–3×. ~10% return 10x+. Adjust by stage and quality.
Should I count my strike price?+
For options, subtract strike × shares from each outcome. For RSUs or founder stock, no strike applies.
How do I value pre-IPO outcomes?+
Use last preferred round valuation as a baseline, then discount 30–50% for common stock illiquidity.
