Did You Know?
How Does Pre/Post Money Valuation Work?
Post-Money Valuation
Post-Money = Pre-Money + Investment. A $5M pre-money company receiving $1M has a $6M post-money valuation.
Investor Ownership
Investor Ownership % = Investment / Post-Money. $1M / $6M = 16.67%. The investor gets 1/6 of the company.
Price Per Share
Price Per Share = Pre-Money / Pre-Money Shares. With 1M shares and $5M pre-money, each share is $5. New shares = Investment / $5.

Frequently Asked Questions
What is pre-money valuation?
The company's value before receiving new investment. If pre-money is $5M and investment is $1M, the investor gets 1/6 = 16.7% ownership, not 20%.
What is post-money valuation?
Post-Money = Pre-Money + Investment Amount. A $5M pre-money with $1M investment creates a $6M post-money valuation. This determines investor ownership percentage.
How is price per share calculated?
Price Per Share = Pre-Money Valuation / Total Pre-Money Shares. With $5M pre-money and 1M shares, each share is $5. New investor shares = Investment / Price Per Share.
What is an option pool?
Reserved shares for future employees, typically 10-20% of post-money. Investors often require the option pool created pre-investment, which dilutes founders more than investors.
How does dilution work?
Each funding round dilutes existing shareholders. If founders own 100% pre-seed, after a 20% seed round they own 80%. After a 25% Series A, they own 60% (80% × 75%).
What determines pre-money valuation?
Revenue multiples, comparable transactions, team experience, market size, traction, and negotiation leverage. Seed: $3-10M. Series A: $10-30M. Series B: $30-100M.
