Stock Profit Calculator

What Is a Stock Profit Calculator?

Stock Profit Calculator is an online tool that computes the gain or loss you have made from buying and selling shares. It takes the key figures about your trade like the purchase price, sell price, and number of shares and instantly tells you your net profit or loss.

Unlike simple subtraction, a good stock profit tool often accounts for transaction costs like brokerage fees, taxes, and commissions, giving you a more realistic result.

Simply put:

Profit = (Sell Price − Buy Price) × Number of Shares − Fees

That’s the basic logic behind most stock profit calculators.

How to Use the Stock Profit Calculator (Step-by-Step)

Using a stock profit calculator is usually as simple as entering a few numbers.

Here’s a breakdown of the typical steps:

Step 1 Enter the Buy Price per Share

This is the price at which you originally purchased the stock.Example: If you bought Apple shares at $150 each, input 150.

Step 2 Enter the Sell Price per Share

This is the price at which you sold the stock (or current market value if selling later).

Example: If you sell for $180 per share, enter 180.

Step 3 Enter Number of Shares

How many shares did you buy?

Example: 50 shares

Step 4 Enter Brokerage / Fees

Most tools allow you to include optional input for brokerage fees or commissions this gives you a net profit figure after costs.

Example: 0.5% brokerage fee or total $20 cost

Step 5 Click Calculate

Once all numbers are entered, press Calculate the tool instantly shows your:

Total Profit or Loss
Profit Percentage
Total Cost and Return

Boom you get your answer.

Example: Real-World Stock Profit Calculation

Let’s say you made the following trade:

Buy Price: $100
Sell Price: $130
Number of Shares: 100
Total Brokerage/Fees: $50

Here’s what happens:

Profit = (130 − 100) × 100 − 50
Profit = 30 × 100 − 50
Profit = $3,000 − $50
Profit = $2,950

So, your net profit would be $2,950.

The calculator will show both profit amount and profit percentage, making it easy to analyze performance.
