How This ROI Calculator Works
This calculator uses two key formulas to measure your investment performance:
ROI = (Final Value - Initial Investment) / Initial Investment × 100
Annualized Return = (Final Value / Initial Investment)(1/years) - 1
In plain English:
- ROI = Your total percentage gain or loss
- Annualized Return = Your yearly average return, accounting for compounding
The annualized return is especially useful for comparing investments held for different time periods. A 100% return over 10 years (about 7.2% annualized) is very different from 100% in 2 years (about 41.4% annualized).
Example Calculation
Let's calculate ROI for a stock investment:
- Initial Investment: $10,000.00
- Current Value: $15,000.00
- Investment Period: 3 years
Step-by-step calculation:
- Calculate gain: $15,000.00 - $10,000.00 = $5,000.00
- Calculate total ROI: $5,000.00 / $10,000.00 × 100 = 50%
- Calculate annualized return: ($15,000.00 / $10,000.00)(1/3) - 1 = 0.1447 = 14.47%/year
Results Summary:
- Total ROI: +50%
- Dollar Gain: +$5,000.00
- Annualized Return: +14.47%/year
- This significantly outperforms the S&P 500's historical average of ~10%
