Angel Investment ROI Calculator

What is this? Angel investing is high-risk, high-reward — most startups fail, but winners return 10-100x. This calculator shows your potential ROI given the equity you own and the expected exit valuation, helping you understand if an investment is worth the risk.

Who it's for: Angel investors evaluating a deal, founders calculating dilution, or anyone curious what a 1% equity stake is worth at a $10M vs $100M exit.
