Stock Profit Calculator
Net gain after fees and taxes
How to use
Enter the buy price, sell price and quantity, plus buy and sell fees and any tax on the sale, to see your net profit and net return. The break-even sell price shows where you stop losing money after costs. Fee and tax rates are fully editable and default to 0 outside Korea.
Q. Which tax should I enter?
A. Enter the transaction tax or capital gains rate that applies in your market and account. The default is 0 because rules differ by country, so check with your broker or tax authority.
Q. What is the break-even sell price?
A. It is the sell price at which net profit is exactly zero after the purchase cost, fees and tax. Selling at the same price you paid still loses money once costs are included.
