Questions / Method

Know what the number means.

01How is average stock price calculated?+

The calculator adds the cost of every purchase lot and fee, then divides the combined cost by the total shares purchased.

02Can I add multiple stock purchases?+

Yes. Add up to 50 purchase lots, each with its own price, share quantity, and optional fee.

03Why can my average price differ from a broker?+

Broker displays may use different fee, fractional-share, corporate-action, transfer, or tax-lot conventions. Use the same basis and precision shown by your broker when reconciling.
