Investing in the stock market requires not just buying and selling shares but also understanding how much profit you’re making relative to your investment. One of the most important metrics investors rely on is the stock margin—a simple yet powerful calculation that shows how profitable a stock trade is. To make this easier for investors and traders, our Stock Margin Calculator helps you quickly determine your profit margin based on your profit and the purchase price of the stock.
This easy-to-use online tool ensures that even beginner investors can calculate their stock margin without complex spreadsheets or formulas. Just input your profit and the original purchase price, and the calculator instantly returns your margin in percentage form.
What Is a Stock Margin?
Stock Margin, also known as profit margin on stock, refers to the percentage of profit made from an investment compared to its original purchase price. It helps investors understand how well a stock has performed in terms of return on investment.
Stock Margin Formula (Simple Equation)
The formula used to calculate stock margin is:
Stock Margin (%) = (Profit ÷ Purchase Price) × 100
For example:
- If your profit is $200 and the purchase price of the stock was $1000,
- Stock Margin = (200 / 1000) × 100 = 20%
This means you earned a 20% profit on your investment.
How to Use the Stock Margin Calculator
Using our online Stock Margin Calculator is incredibly simple. Here’s how you can use it:
- Enter your stock profit in the field labeled “Stock Profit ($)”.
- Enter the stock purchase price in the field labeled “Stock Purchase Price ($)”.
- Click on the Calculate button.
- Instantly, your stock margin percentage will be displayed below.
That’s it—fast, accurate, and no technical knowledge required!
Example Calculation
Let’s look at a quick real-world example:
- Suppose you bought a stock at $1500 and sold it for $1800.
- Your profit = $1800 – $1500 = $300
- Using the calculator:
- Enter 300 as Stock Profit
- Enter 1500 as Stock Purchase Price
- The result would be:
- Stock Margin = (300 / 1500) × 100 = 20%
So, your profit margin on the stock investment is 20 percent.
