A stock profit calculator is one of the most essential tools for traders and investors. It quickly tells you how much profit or loss you’ll make based on your buy price, sell price, quantity, and fees—without doing the math manually.
In this guide, we’ll walk you through the process of using a stock profit calculator to make better trading decisions.
What Is a Stock Profit Calculator?
A stock profit calculator helps traders and investors estimate the net profit or loss from a trade. It factors in:
- Buy price
- Sell price
- Number of shares
- Brokerage fees and taxes (optional)
- Resulting net gain or loss
Whether you’re day trading or investing long-term, this tool gives instant clarity on your returns.
Why Use a Stock Profit Calculator?
Using a stock profit calculator ensures you:
- Know your exact profit or loss before exiting a trade
- Avoid emotional trading decisions
- Account for hidden costs like brokerage or taxes
- Plan better entry and exit points
Step-by-Step: How to Use a Stock Profit Calculator
Step 1: Enter Buy Price
This is the price at which you purchased each stock. For example, if you bought shares at ₹250, enter “250” in the buy price field.
Step 2: Enter Sell Price
This is the price at which you plan to sell or have sold the stock. If you expect to sell at ₹300, enter “300”.
Step 3: Enter Quantity
Add the number of shares bought. For example, if you bought 100 shares, enter “100”.
Step 4: Add Fees (If Applicable)
If your calculator allows, input any brokerage fees, taxes, or commissions. Some calculators auto-calculate based on your broker.
Step 5: Click Calculate
The calculator will instantly show:
- Gross Profit = (Sell Price – Buy Price) × Quantity
- Net Profit = Gross Profit – Fees
- Return (%) = (Net Profit ÷ (Buy Price × Quantity)) × 100
Example Calculation
Let’s say you:
- Bought at ₹250
- Sold at ₹300
- Quantity: 100 shares
- Total brokerage and tax: ₹100
Gross Profit: (300 – 250) × 100 = ₹5,000
Net Profit: ₹5,000 – ₹100 = ₹4,900
Return: (₹4,900 / ₹25,000) × 100 = 19.6%
Tips for Accurate Results
- Always include fees if you’re calculating net profit
- Use exact trade quantities—partial trades affect outcomes
- Double-check stock prices before entering
When to Use a Profit Calculator
- Before placing a trade (to estimate returns)
- After a trade (to calculate actual profit/loss)
- To compare trades or strategies
- For record keeping and tax planning
