Stock Profit Calculator
Work out profit or loss on a trade including fees and break-even price.
How trade profit is worked out
Profit equals proceeds from selling minus the cost of buying, with fees on both sides. The break-even price is the sell price where you neither gain nor lose after fees.
Do not forget tax
Gains are usually taxed. Holding for longer than a year can lower the rate in some countries. This tool does not include tax.
