Stock Profit Calculator
A stock profit calculator computes net P&L and return percentage from buy price, sell price, share count, and commissions. Stock and ETF traders use it to see realized profit after fees instead of relying on gross price difference alone.
Enter buy price, sell price, shares, and commissions to see net profit or loss.
Frequently asked questions
Should I include commissions in stock profit calculations?
Yes. Commissions and fees reduce net returns. Omitting them overstates performance, especially on small positions and higher-frequency strategies.
How is net stock trading profit calculated?
Net profit = (sell price − buy price) × shares − commissions on both sides. Return % is net profit divided by total cost basis including fees.
