Standard ROI measures total return relative to the original investment: (final value − initial investment) ÷ initial investment.
When a holding period is provided, annualized ROI is estimated using: (final ÷ initial)^(1/years) − 1.
Examples
- $10,000 growing to $12,500 → 25% ROI
- If the same result happened over 3 years, annualized ROI is lower than total ROI
- If final value is below initial investment, ROI is negative
