Calculators
Every calculator runs in your browser and sends nothing anywhere. Each page also explains a worked example in plain text, so the arithmetic is visible even without JavaScript.
Calculator Cap table and dilution simulator
Add your SAFEs and notes, set the round, and see the price per share, each investor's conversion and the cap table after the round.
Calculator SAFE vs note calculator
The same check written three ways converts into different numbers of shares. This calculator puts them side by side.
Calculator Runway and burn calculator
How many months the money in the bank lasts, when it runs out, and when you should start raising the next round.
Calculator How much to raise
Size a round from the plan, not from a headline: what it costs to reach the milestones that justify the next round, plus a buffer for delays.
Calculator Exit waterfall calculator
Enter the preferred classes and an exit value to see the payout to each class and to common, including which classes would convert.
