Confused about equity compensation

The equity problem is real

You get an offer letter. It says you'll get 50,000 options at a $2 strike price. Your boss says it's worth $500k. Your friend says you'll never see a dime. Who's right?

  • Founders don't explain the scenario
  • You don't know the company's runway
  • Nobody talks about dilution in future rounds
  • Tax on exit is never explained
  • You guess, and guess wrong

Cliff does the math for you

Enter your grant amount, strike price, vesting schedule, and the company details. Cliff models realistic outcomes: Series A, B, C paths. Acquisition. IPO. Failure. It shows you the money in each scenario, after taxes, after dilution.

  • Accurate dilution modeling across funding rounds
  • Real-world tax calculations (AMT, NSOs, ISOs)
  • 1000+ exit scenarios generated automatically
  • Compare multiple offers side by side
  • Export your analysis for lawyers or advisors

Frequently Asked

How accurate is the dilution calculation?

We model each funding round with realistic entry valuations and typical share count assumptions. We also let you override with actual numbers if you have them. The math is audited by a CPA.

Do you store my equity information?

No. All calculations happen in your browser. We don't see, store, or retain any of your equity data. Your analysis is yours alone.

Can I use this to compare multiple offers?

Yes. Pro and Team plans let you compare 5 or unlimited offers side by side. You'll see the wealth outcome in each scenario for each offer.

What about ISOs vs NSOs vs RSUs?

We handle all three. ISOs get long-term capital gains treatment. NSOs and RSUs are taxed as compensation income. We calculate your exact tax burden.

Is there a mobile app?

Cliff works on any device, but we designed it for desktop first. A native iOS/Android app is coming in Q3 2026.

Can I use this with my lawyer or CPA?

Yes. Export a detailed PDF of your analysis. It includes assumptions, tax treatment, and scenario breakdowns. Perfect for professional review.
