Understanding Your Stock Profit

Investing in the stock market can be a rewarding venture, but accurately calculating your profit is crucial for understanding your returns. It's not just about the difference between your buy and sell price; various fees and taxes can significantly impact your net gain.

How the Stock Profit Calculator Works

Our Stock Profit Calculator helps you determine the true profitability of your stock trades by factoring in all relevant costs. Here's a breakdown of the inputs and what they represent:

  • Number of Shares Purchased: The total quantity of stock units you bought.
  • Buy Price per Share ($): The price you paid for each individual share when you acquired them.
  • Sell Price per Share ($): The price you received for each individual share when you sold them.
  • Brokerage Fee (Buy) ($): The commission or fee charged by your broker when you purchased the shares. This is a direct cost of your investment.
  • Brokerage Fee (Sell) ($): The commission or fee charged by your broker when you sold the shares. This reduces your total proceeds.
  • Capital Gains Tax Rate (%): The percentage of your profit that is subject to capital gains tax. This rate can vary based on your income, holding period (short-term vs. long-term), and local tax laws.

Key Profit Metrics Explained

The calculator provides several important metrics to give you a comprehensive view of your trade's performance:

  • Total Initial Investment: This is the total amount of money you put in, including the cost of the shares and any brokerage fees incurred during the purchase.
  • Total Proceeds from Sale: This is the total cash you received from selling your shares, after deducting any brokerage fees from the sale.
  • Gross Profit (Before Tax & Fees): This is the simple profit from the price difference (Sell Price – Buy Price) multiplied by the number of shares, before considering any fees or taxes.
  • Total Brokerage Fees: The sum of your buy and sell brokerage fees.
  • Taxable Profit: This is the portion of your profit that is subject to capital gains tax. It's calculated as your gross profit minus all brokerage fees. If this value is negative, you have a loss, and no capital gains tax is applied.
  • Capital Gains Tax: The actual dollar amount of tax you owe on your taxable profit.
  • Net Profit: This is your true profit after all costs, including brokerage fees and capital gains tax, have been deducted. This is the money you actually get to keep.
  • Return on Investment (ROI): Expressed as a percentage, ROI measures the efficiency of your investment. It shows how much profit you made relative to your initial investment. A higher ROI indicates a more successful trade.

Example Calculation

Let's walk through an example to illustrate the calculation:

  • Shares Purchased: 100
  • Buy Price per Share: $50.00
  • Sell Price per Share: $60.00
  • Brokerage Fee (Buy): $5.00
  • Brokerage Fee (Sell): $5.00
  • Capital Gains Tax Rate: 15%
  1. Total Cost of Shares: 100 shares * $50.00/share = $5,000.00
  2. Total Revenue from Shares: 100 shares * $60.00/share = $6,000.00
  3. Total Initial Investment: $5,000.00 (shares) + $5.00 (buy fee) = $5,005.00
  4. Total Proceeds from Sale: $6,000.00 (revenue) – $5.00 (sell fee) = $5,995.00
  5. Gross Profit (Before Tax & Fees): $6,000.00 – $5,000.00 = $1,000.00
  6. Total Brokerage Fees: $5.00 (buy) + $5.00 (sell) = $10.00
  7. Profit Before Tax: $1,000.00 (gross profit) – $10.00 (total fees) = $990.00
  8. Taxable Profit: Since Profit Before Tax is positive, Taxable Profit = $990.00
  9. Capital Gains Tax: $990.00 * 15% = $148.50
  10. Net Profit: $990.00 (profit before tax) – $148.50 (capital gains tax) = $841.50
  11. Return on Investment (ROI): ($841.50 / $5,005.00) * 100 = 16.81%

By using this calculator, you can quickly assess the financial outcome of your stock trades and make more informed investment decisions.
