Understand what you actually paid
Add each purchase and its fees. Weighted average cost shows what you paid per share. Example: 2 shares at 100 and 3 at 110, with no fees, average 106.
WHAT THIS CALCULATION ASSUMES
Includes purchases and buy fees only. Sales, tax lots and currency effects are excluded. Current price is entered manually.
ONE QUESTION WORTH ASKING
A lower average cost doesn't necessarily justify another purchase. The business and its risks still matter.
