How to use this calculator

  • Enter founder ownership before the round.
  • Add pre-money valuation and investment amount.
  • Enter employee option pool percentage after the round.
  • Review founder ownership and cap table balance.

What the result means

The result shows whether founder ownership remains strong after allocating equity to investors and employees.

Investor ownership = investment ÷ post-money valuation. Founder after round = founder before × (1 - investor ownership - employee option pool).

This simplified model does not include liquidation preferences, warrants, SAFEs, or different share classes.

Example calculation

Founder ownership is 75%, pre-money is $10M, investment is $3M, and employee pool is 12%. Investor ownership is about 23.08%, and founder ownership after round is about 48.69%.

Tips for better results

  • Protect founder control while keeping enough employee equity to hire well.
  • Negotiate whether the option pool is pre-money or post-money.
  • Model future rounds before finalizing the current round.
  • Keep the cap table understandable for future investors.

FAQ

How much ownership should founders keep?

Founders usually try to keep enough ownership for control, motivation, and future dilution capacity.

What is a healthy startup cap table?

A healthy cap table balances founder ownership, investor incentives, and employee option pool needs without excessive early dilution.

How much equity should employees receive?

Employee equity varies by stage, role, and market. Many startups reserve an option pool around 10% to 20%.

How does dilution affect founder ownership?

Dilution reduces the founder percentage when new shares are issued for investors, employees, or other stakeholders.

How much equity do investors usually require?

Investor equity depends on round size, valuation, stage, risk, and market demand.
