## Key Metrics Explained

### ROI (Return on Investment)
The total percentage gain or loss on your investment:

**ROI = ((Final Value - Initial Investment) / Initial Investment) × 100**

### CAGR (Compound Annual Growth Rate)
The annualized return that smooths out year-to-year volatility:

**CAGR = (Final Value / Initial Investment)^(1/Years) - 1**

### Real vs. Nominal Returns
- **Nominal Return:** The actual percentage gain without accounting for inflation
- **Real Return:** The inflation-adjusted return showing true purchasing power

Example: A 10% return with 3% inflation = only 7% real purchasing power gain
