Active stock trading and long-term investing require meticulous tracking of entry prices, exit prices, and platform trading fees. Ignoring broker commissions can turn a seemingly profitable trade into a net loss. A stock profit calculator provides absolute clarity on your capital gains, helping you determine the exact mathematical "break-even" price your stock must hit just to cover the transaction costs.

Stock Profit Equation

Gross Profit = (Sell Price - Buy Price) × Number of Shares
Net Profit = Gross Profit - (Buy Commission + Sell Commission)
Return on Investment (ROI) = (Net Profit / Total Investment Cost) × 100

How to Use This Calculator

  1. Enter the total Number of Shares you purchased.
  2. Input the Buy Price per share and the associated broker Buy Commission.
  3. Enter the targeted or actual Sell Price per share and the Sell Commission.
  4. Click Calculate to instantly view your Net Profit, ROI percentage, and Break-Even price.

Frequently Asked Questions (FAQ)

What is a Break-Even price in stock trading?

The break-even price is the exact price per share you must sell your stock at so that your total revenue perfectly equals your original investment plus all broker commissions. If you sell exactly at the break-even price, your net profit is zero.

Does this calculation include capital gains tax?

No. This calculator computes your net trading profit before taxes. Depending on your country and how long you held the asset (short-term vs. long-term capital gains), a percentage of your final net profit will be owed to the government at tax time.
