Determine Your Trading Profitability

This calculator helps you quickly determine the profit or loss from a stock trade. Enter the number of shares, your purchase price, your selling price, and any commissions to see your net profit and return on investment (ROI). It's a vital tool for any stock market investor to track their performance.

The Profit Formula Explained

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

How to Use the Calculator

  1. Number of Shares: Enter the quantity of shares you traded.
  2. Buy Price: Enter the price per share at which you purchased the stock.
  3. Sell Price: Enter the price per share at which you sold the stock.
  4. Commission (optional): Enter any commission fees for the trade. Many brokers now offer commission-free trading.

Real-World Example

You buy 50 shares of a company at $100 per share. You later sell all 50 shares at $115 per share. You paid a $5 commission to buy and a $5 commission to sell.

  • Total Cost: ($100 * 50) + $5 = $5,005
  • Total Proceeds: ($115 * 50) - $5 = $5,745
  • Net Profit: $5,745 - $5,005 = $740
  • ROI: ($740 / $5,005) * 100 ≈ 14.8%

Frequently Asked Questions (FAQ)

  • Does this calculator account for taxes? No. Your profits from stock trading are subject to capital gains tax. This calculator shows your profit before taxes.
  • What about dividends? This calculator does not include any dividends you may have received while holding the stock. Dividends would be an additional part of your total return.
  • What if I bought shares at different prices? You should calculate your average cost per share. To do this, divide the total amount you spent to acquire all your shares by the total number of shares you own. Use this average price as your 'Buy Price'.
