Cap Table Calculator — free online tool

Raising money and trying to picture who owns what afterwards? It's easy to lose the thread once you add an investment and an option pool on top of your starting value. We added a free tool that does the math for you — Cap Table Calculator — right in your browser.

What it does

You type in the pre-money value, the investment, and the size of the option pool. It works out the post-money value, the investor's percentage, and how much equity the founders keep. No spreadsheet, no formulas to remember.

Nothing leaves your device

The whole thing runs inside your browser. Your numbers are never uploaded and never saved anywhere. Close the tab and they're gone — nobody else sees what you put in.

How to use it

  1. Open Cap Table Calculator and enter your pre-money value.
  2. Add the investment amount and the option pool size.
  3. Read off the post-money value, investor share and founders' equity.

It's free with no limit. There are more small tools on the Apps page.
