How to use this calculator

  • Enter the SaaS operating or financing inputs that match the current month or round.
  • Use recurring revenue only where the input asks for MRR or ARR.
  • Click calculate to see the main result, supporting metrics, health score, and status.
  • Use the result as a planning estimate before making pricing, hiring, fundraising, or cap table decisions.

What the result means

The result shows how fundraising changes founder, investor, and employee ownership. A balanced cap table leaves enough founder motivation, investor upside, and employee option capacity.

Post Money = Pre Money + Investment; Investor Ownership = Investment / Post Money; Founder After = Founder Before × (1 - Investor Ownership - Option Pool)

Actual equity outcomes depend on whether the option pool is created pre-money or post-money and whether the cap table is calculated on a fully diluted basis.

Example calculation

With a $5,000,000 pre-money valuation and a $1,000,000 investment, post-money valuation is $6,000,000 and investor ownership is 16.67% before option pool effects.

Tips for better results

  • Compare the result with several prior months instead of one isolated period.
  • Model conservative, base, and aggressive cases before making decisions.
  • Keep recurring revenue, one-time services, and discounts separate.
  • Review the result together with churn, burn, runway, and ownership impact.

FAQ

How much founder equity should remain after a SaaS seed round?

Founder equity after a seed round depends on valuation, round size, number of founders, option pool, and previous dilution.

How do I calculate SaaS investor equity after funding?

Divide the investment amount by post-money valuation, then adjust for option pool and fully diluted share treatment.

Does an option pool reduce founder equity?

Yes, especially when it is created pre-money. A pre-money option pool usually dilutes existing holders before the new investor buys shares.

What founder ownership is healthy before Series A?

There is no single rule, but founders usually need enough ownership to stay motivated through future rounds and exit scenarios.

How should SaaS founders model equity before fundraising?

Model founder, investor, and option pool ownership across multiple rounds using fully diluted ownership, not only the current round headline percentage.
