How the stock profit calculator works
Gross profit = (sell − buy) × shares. Net = gross − fees − tax, where tax applies only to positive gains at the rate you enter.
Example
Using the default inputs (Shares: 100; Buy price: $45.00; Sell price: $72.00; Fees (total): $10.00; Capital gains tax rate: 15%), the calculator returns net profit of $2,287. Change any field above to see your own result and charts update instantly.
