How to Use the Stock Profit Calculator
Enter Stock Prices
Start by entering the buy price per share and sell price per share. These are the actual prices at which you purchased and sold (or plan to sell) your stock shares.
Set Number of Shares
Enter the total number of shares you bought or sold. This could be any number - from a few shares to thousands, depending on your investment size.
Add Trading Costs
Include the commission charged by your broker per trade. This is typically charged on both buy and sell transactions, so the total commission cost will be doubled in the calculation.
Set Tax Rate
Enter your applicable tax rate for capital gains. This varies by country and your income bracket. In the US, it's typically 0%, 15%, or 20% for long-term capital gains.
Review Results
The calculator shows your gross profit/loss, net profit after taxes, return on investment percentage, break-even price, and detailed breakdown of all costs and profits.
