How to use the Stock Profit Calculator

Calculate realized share-trading profit after fees and compare it with your cost basis.

Calculation formula

Net profit = (sell price − buy price) × shares − total fees. Return (%) = net profit ÷ (buy price × shares + fees) × 100.

1. Enter values using the units shown beside each field.
2. Review whether the example assumptions match your situation.
3. Run the calculator and compare the key metrics.
4. Use the source data or official rates when precision matters.

Known limitations
