What Is Startup ROI?

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

ROI = ((Exit Value - Investment) / Investment) × 100
CAGR = (Exit Value / Investment)^(1/t) - 1

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%.

Key Factors Affecting ROI
1

Valuation Growth

The startup's increase in valuation from investment to exit

2

Dilution

Ownership percentage decrease from subsequent funding rounds

3

Holding Period

Time from initial investment to exit or liquidity event

4

Exit Scenario

Acquisition, IPO, or secondary sale affects final returns
