Estimate how much of the company an investor receives for a given investment. The tool shows post-money ownership, founder dilution, and potential value at exit.
The result shows the financing impact on ownership, valuation, conversion, or dilution. A stronger result protects founder ownership while preserving enough incentive for investors and employees.
This estimate is educational and should not replace legal, tax, or fundraising advice. Real term sheets may include preferences, pro rata rights, participation, vesting, and other provisions.
A $1,000,000 investment into a $4,000,000 pre-money valuation gives the investor 20% ownership and a $10,000,000 share of a $50,000,000 exit before preferences.
Seed investor ownership often depends on round size, valuation, lead investor requirements, and option pool needs.
Divide the investment amount by post-money valuation, where post-money equals pre-money valuation plus investment.
Investor ownership is the percentage of fully diluted shares received after the round, including negotiated option pool treatment.
Higher investor ownership reduces founder voting and economic control and can affect future fundraising flexibility.
Multiply investor ownership by exit value, then adjust for liquidation preferences, participation rights, and other preferred stock terms.
