🧮 What Is a Capital Gains Stock Calculator?

A Capital Gains Stock Calculator helps investors determine how much profit they’ve earned (or lost) after selling their stocks and how much tax they owe based on their country’s capital gains tax rate.

This tool simplifies the complex math behind investment returns by providing instant results such as:

• Total Investment Amount
• Total Sale Value
• Gross Capital Gain or Loss
• Tax Payable
• Net Profit After Tax

It’s ideal for investors who want a clear picture of their post-tax earnings, especially when filing taxes or evaluating portfolio performance.

💡 How to Use the Capital Gains Stock Calculator

Using the calculator is straightforward and takes less than a minute. Follow these steps to calculate your results:

Step 1: Enter the Purchase Price per Share

Input the price at which you originally bought each share.
For example, if you purchased shares at $50 each, type 50 in the box.

Step 2: Enter the Selling Price per Share

Type in the price you sold your shares for.
If you sold them at $80 each, enter 80.

Step 3: Add the Number of Shares

Enter how many shares you bought and sold.
For example, if you owned 100 shares, input 100.

Step 4: Choose the Holding Period

Select whether your investment was:

• Short-Term (less than 1 year), or
• Long-Term (more than 1 year).

This may affect your applicable tax rate.

Step 5: Enter Your Capital Gains Tax Rate

Provide your tax rate percentage. For example, if your tax rate is 15%, type 15.

Step 6: Click “Calculate”

When you click the Calculate button, the tool displays a progress animation (lasting about 3 seconds) and then shows detailed results including your total investment, total sale value, capital gain, tax payable, and net profit after tax.

You can then:

• Copy the results to your clipboard, or

📊 Example of Capital Gains Calculation

Let’s take an example to see how the tool works in real life:

• Purchase Price per Share: $50
• Selling Price per Share: $80
• Number of Shares: 100
• Tax Rate: 15%

Step 1: Total Investment = 50 × 100 = $5,000
Step 2: Total Sale Value = 80 × 100 = $8,000
Step 3: Capital Gain = 8,000 – 5,000 = $3,000
Step 4: Tax Payable = 15% of 3,000 = $450
Step 5: Net Profit After Tax = 3,000 – 450 = $2,550

✅ Result: You made a net profit of $2,550 after tax.

The calculator automatically handles all these calculations instantly.
