How this calculator works

Average price = total amount invested ÷ total quantity, where each purchase's amount is quantity × price. Brokerage and other charges are not included. This is a planning tool and not investment advice.

Frequently asked questions

What does averaging down mean?

It means buying more of a stock after its price falls, which lowers your average buy price. It also raises your exposure to that stock, so it carries risk.

Does this include brokerage?

No. Add brokerage and charges separately if you want a net figure.
