Option pool calculator


Calculate the value of your employee stock option pool for your future hires using Carta’s modeling tool.

An option pool is the equity that founders set aside to give to future hires. But sizing your employee option pool can be a challenge as an early founder when you might not know how many employees or advisors you’ll have in the future.

Input your seed round information and expected hires, and our free Option Pool Modeling Tool for pre-seed and seed-stage founders helps answer:

  • How does my option pool stack up against anticipated hires?
  • How does my seed round compare to the rest of the market?
  • What would my employees’ equity be worth upon exit?
  • How should I size my option pool?
  • What is “normal” for employee stock option pools at seed?*


Make more informed decisions around how much equity to safely offer employees and advisors with Carta. Companies with up to 25 stakeholders and up to $1M raised can even try Carta for free.
