Questions people ask
How is the average share price calculated?
Add up what you paid for every purchase (shares × price) and divide by the total number of shares. It is a weighted average, so bigger purchases count for more.
Does buying more at a lower price help?
It lowers your average cost, so the share needs to rise less for you to break even. It also puts more money into the same company, so the risk grows too.
Should I include brokerage?
For a true break-even price, yes. Add the fees to the price you paid on each line, or work them out with the stock profit calculator.
What format should I type?
One purchase per line: the number of shares, a space, then the price per share, such as 500 82.50. You can also write 500 @ 82.50.
