Calculators
What it does
A library of 32 interactive calculators for founders: valuation, SAFE notes, runway, unit economics, stock options, hiring costs, marketing payback, and more. Each one sits next to a short guide that explains what it measures and how to use it. Save a calculation to come back to it later, and star the ones you use most.

Frequently asked questions
Can my team see my saved calculations?
No. Each person sees only their own saved runs and favorites.
Why did an old saved calculation disappear?
Each calculator keeps your 50 most recent runs. Once you save more than that, the oldest is removed.
Why can't I save in the Cap Table Simulator?
It doesn't have Save calculation. Click Copy shareable link and keep that link.
Is the Cap Table Simulator the same as my real cap table?
No. It's a standalone calculator for trying out scenarios. To manage your actual stakeholders and rounds, use Cap table.
