📖How to Use the Portfolio Calculator
1Add Your Holdings
Enter the name, purchase price, current price, and number of shares for each position. Add up to 10 holdings.
2Review Results
Each holding shows its portfolio weight (%), individual return rate, and P&L. The donut chart displays the allocation breakdown.
3Weighted Average Return
This is the true portfolio return weighted by investment amount — more meaningful than a simple average of individual returns.
