Stock Profit Calculator

Calculate your estimated profit or loss on a stock trade using your buy price, sell price, number of shares and trading fees.

Your Details

Overview

A stock profit calculator helps you estimate the gain or loss on a trade by comparing your buy price and sell price across the number of shares you traded, while also accounting for basic transaction fees. It is useful for reviewing completed trades or testing a possible exit price before you sell.

How it works

The calculator first works out your total cost basis by multiplying the buy price by the number of shares and adding the buy fee. It then calculates your net sale proceeds by multiplying the sell price by the number of shares and subtracting the sell fee. Your profit or loss is the difference between net sale proceeds and total cost. The return percentage shows that result relative to your total cost, and the break-even sell price shows the price per share needed to cover both your purchase cost and selling fee.

How to use this calculator

  1. 1Enter the price paid per share when you bought the stock.
  2. 2Enter the price received or expected per share when you sell.
  3. 3Add the number of shares in the trade.
  4. 4Include any buy and sell fees charged by your broker.
  5. 5Review your estimated profit or loss, return percentage and break-even sell price.
