Gross profit
Gross profit equals target sell price times shares minus buy price times shares.
Formula guide
Estimated fees
The tool multiplies the target sell value by your estimated fee rate so you can see a simplified net outcome.
Net return
Net return uses net profit divided by the original buy value, which makes strategies easier to compare.
Break-even idea
If the target sell price is only slightly above the buy price, fees may still leave the trade flat or negative.
When to use this tool
Setting exit targets
Check how much net reward is left after fees before choosing a take-profit level.
Comparing multiple trades
Use net return rather than price move alone when deciding which setup offers the best expected outcome.
Planning partial exits
Run the calculator with different share counts to see the effect of scaling out in tranches.
Checking fee sensitivity
Increase the fee rate to see whether your strategy still works under less favorable execution costs.

FAQ
Does this include taxes?
Only through your own fee-rate estimate. If your market has stamp duty or extra taxes, include them in that input.
Why is net profit more useful than gross profit?
Because gross profit ignores frictions. Net profit is closer to the number that matters after execution costs.
Can I use the calculator for ETFs too?
Yes. Enter the ETF buy price, target sell price, shares, and a fee assumption.
What if the trade is a loss?
The calculator still works. If sell price is below buy price, the result will show a negative gross and net outcome.
