When to use this calculator

Use this when you buy the same stock multiple times at different prices and want the weighted average cost. It helps investors understand their true cost basis after averaging up or averaging down.

How to interpret the result

The average price is the total invested amount divided by total shares. If charges are included, the average price reflects a more realistic cost per share.

Common mistakes to avoid

Do not use a simple average of prices when purchase quantities differ. Weighted average price gives the correct result because each lot may have a different number of shares.
