💡 What Is a Stock Market Gain Calculator?

A Stock Market Gain Calculator is a financial tool designed to help you determine how much money you’ve gained or lost from buying and selling stocks.

It uses basic investment data — such as purchase price, selling price, number of shares, and transaction fees — to calculate your net profit, percentage gain, and total return.

This tool is particularly useful for:

Individual investors tracking their stock performance
Traders reviewing multiple transactions
Financial planners preparing investment summaries
Beginners learning how gains and returns are calculated

⚙️ How to Use the Stock Market Gain Calculator (Step-by-Step)

Enter Purchase Price per Share:
Input the amount you paid for one share when you bought the stock.
Enter Selling Price per Share:
Input the price at which you sold (or plan to sell) your shares.
Add Number of Shares:
Enter how many shares you purchased in total.
Include Fees (Optional):

🧮 Example: How the Stock Market Gain Calculator Works

Let’s say you invested in Tesla stock and bought 100 shares at $220 each, then sold them at $275 per share.

Field	Value
Purchase Price	$220
Selling Price	$275
Shares Bought	100

✅ Result:

Total Investment = $220 × 100 = $22,000
Selling Value = $275 × 100 = $27,500
Profit = $27,500 – $22,000 = $5,500
Percentage Gain = ($5,500 ÷ $22,000) × 100 = 25%

So, your total gain is $5,500, and your return is 25%.

📊 Formula Used in the Calculator

Here’s the basic formula behind the calculator:
