Startup ROI (Return on Investment) measures the profit or loss relative to initial capital invested. It accounts for valuation growth, dilution, and exit returns.
Formula Overview
Example
An investor puts $100,000 into a startup at a $1M valuation for 10%. If the startup exits at $10M after 5 years, final equity value = $1M → ROI = 10×, CAGR ≈ 58%.
Valuation Growth
The startup's increase in valuation from investment to exit
Dilution
Ownership percentage decrease from subsequent funding rounds
Holding Period
Time from initial investment to exit or liquidity event
Exit Scenario
Acquisition, IPO, or secondary sale affects final returns
