Frequently Asked Questions
How is stock profit calculated?
Subtract your total cost (purchase price × shares plus commissions) from your total proceeds (sale price × shares).
Should I include commissions?
Yes, for an accurate net result. Many brokers are commission-free for US stocks, so you can leave it at 0.
Does this calculate capital gains tax?
No. Taxes depend on your holding period and tax bracket. This shows pre-tax profit only.
What is percentage return?
Your profit divided by your total cost, expressed as a percent — useful for comparing trades of different sizes.
Can I use this for options?
Use the Options Profit Calculator for calls and puts; this tool is for common stock.
