A lower average cost does not erase a loss if the price stays where it is, and the loss amount can grow as the number of shares increases.

For reference only. Fees and taxes are not included, and investment decisions and any resulting gains or losses are your own responsibility.

How to use

Enter the shares you hold, your average cost and any additional purchases, and it calculates your new average cost, the total invested and the rise needed to break even. Set a target average cost and it works backwards to tell you how many more shares to buy.

Q. Are fees and taxes included?

A. No. It uses only the prices and quantities you enter; fees and taxes are not included.

Q. Does averaging down reduce my loss?

A. It lowers your average cost, but if the price stays where it is the loss does not disappear, and the loss amount can grow as you hold more shares. Check both the return and the amount.
