Understanding these calculations:
- Total Investment Gain/Loss = Ending Value - Starting Value - Net Contributions. This shows growth purely from market performance.
- Simple ROI (approximate) = Gain/Loss divided by (Starting Value + 50% of Net Contributions). This is a basic way to account for cash flows.
- Simplified Annualized ROI = Calculated like a Compound Annual Growth Rate (CAGR) on the Starting Value to reach (Starting Value + Total Investment Gain/Loss) over the duration.
- Important: For portfolios with significant and irregular cash flows, true Time-Weighted Return (TWR) or Money-Weighted Return (IRR/XIRR) are more accurate performance measures. These are complex and typically provided by your financial platform. This tool provides simplified estimates.
