ROI Calculator

ROI (Return on Investment) measures how much profit you made relative to your investment cost. Formula: ROI = ((Return − Cost) / Cost) × 100. A 20% ROI means you gained $20 for every $100 invested.

It depends on the context. Stock market averages around 7–10% annually. Real estate often targets 8–12%. A business project ROI of 15–30% is generally considered good. The "right" ROI depends on risk, time horizon, and opportunity cost.

Annualized ROI adjusts total ROI to a per-year basis, allowing fair comparison between investments held for different durations. Formula: Annualized ROI = ((1 + ROI/100)^(1/years) − 1) × 100.
