Angel Investment ROI Calculator

Analyze potential returns on startup equity investments

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.

Frequently Asked Questions

What is an angel investor?

An angel investor uses personal capital to invest in early-stage startups, typically providing $10K-$500K. They often offer mentorship and connections in addition to capital.

What return do angels expect?

Angels typically target 10-20x return on successful investments, knowing most startups will fail. This compensates for the high risk of early-stage investing.

What is a SAFE note?

Simple Agreement for Future Equity — a financial instrument where investors give money to a startup in exchange for the right to receive equity later at a discount to the next priced round.

How do angels get paid?

Through a liquidity event — acquisition, IPO, or secondary sale. Unlike debt, angels have no guaranteed return. Their equity converts to cash only when the company exits.
