Understanding Equity Dilution

Dilution happens when new shares are issued, reducing your percentage ownership. Even though your percentage decreases, your absolute value may increase if the company valuation grows. A smaller slice of a bigger pie can be worth more than 100% of nothing.

Frequently Asked Questions

Common questions about the Founder Equity Dilution Calculator - Cap Table Calculator

Not necessarily. Dilution is the price of growth capital. If you raise $1M at a $4M pre-money, you give up 20% ownership but gain capital to grow the company. The key is whether the growth from that capital exceeds the dilution cost.
