ROI Calculator: Understanding Return on Investment
The **ROI Calculator (Return on Investment Calculator)** is a financial tool that measures the profitability of your investment. It tells you how much you gained or lost relative to your initial investment, expressed as a percentage.
ROI Formula
ROI (%) = [(Final Value - Initial Investment) / Initial Investment] × 100 Annualized ROI = [(Final Value / Initial Investment) ^ (1 / Years) - 1] × 100
Example Calculation
Suppose you invested **10,000** in stocks, and after **2 years**, the investment grew to **15,000**:
- Profit = 15,000 - 10,000 = 5,000
- ROI = (5,000 / 10,000) × 100 = 50%
- Annualized ROI = ((15,000 / 10,000) ^ (1/2) - 1) × 100 = 22.47%
