How this is calculated
ROI % = ((final − initial) / initial) × 100
Annualized % = ((final / initial)^(1/years) − 1) × 100
Annualized % = ((final / initial)^(1/years) − 1) × 100
Example: $1,000 grown to $1,500 over 3 years → +50% total ROI, or about +14.5% annualized — the annualized figure lets you compare investments held for different lengths of time on equal footing.
