    Return on Investment

    A performance metric calculated by dividing the net gain from an investment by its cost, expressing the percentage return relative to the initial outlay.

    Return on Investment (ROI) is a performance metric that measures the profitability of an investment by dividing the net gain (or loss) by the initial cost, typically expressed as a percentage. For an angel investor who puts $100,000 into a startup and exits at $400,000, the ROI would be 300% ($300,000 gain ÷ $100,000 investment × 100).

    The calculation follows a straightforward formula: ROI = (Current Value - Initial Investment) / Initial Investment × 100. This metric provides a universal language for comparing investment performance across different asset classes, time periods, and deal sizes. A venture capital fund might report a 25% ROI across its portfolio, while a specific startup investment could yield 1,000% or result in a -100% loss if the company fails.

    Why It Matters

    ROI serves as the primary scorecard for angel investors evaluating whether their capital deployment strategy works. Unlike absolute dollar returns, ROI accounts for the size of the investment, allowing meaningful comparisons between a $50,000 stake that returns $200,000 and a $500,000 stake that returns $1 million—the former delivers a superior 300% ROI versus 100%. For portfolio construction, understanding historical ROI patterns helps investors calibrate their expectations: angel investing typically requires targeting ROI multiples of 10x or higher on successful exits to offset the 50-70% failure rate in early-stage companies.

    Example

    An angel investor writes a $75,000 check for 5% equity in a SaaS startup at a $1.5 million valuation. Four years later, the company gets acquired for $20 million. The investor's stake is now worth $1 million (5% of $20 million), representing a net gain of $925,000. The ROI calculates to approximately 1,233% ($925,000 ÷ $75,000 × 100). However, if the investor had participated in a subsequent funding round, investing another $50,000 at a higher valuation that diluted to 4% total ownership, the total investment becomes $125,000 with an exit value of $800,000 (4% of $20 million), reducing the overall ROI to 540%—still strong, but demonstrating how follow-on investments affect returns.
