🔧 How to Use the Buy and Sell Profit Calculator (Step-by-Step)
Using the calculator is straightforward. Here’s how to do it:

Step 2: Enter the Selling Price per Unit
Input the price at which you sold (or plan to sell) each unit. For instance, if you’re selling at $25.00 per item, type 25.00.
Step 3: Enter the Quantity
Specify how many units you bought and sold. If you dealt with 10 items, simply enter 10.
Step 4: Input Total Fees (Optional)
If you incurred any costs—like platform fees, shipping, or transaction charges—add them here. This field defaults to 0 if left blank.
Step 5: Click “Calculate”
Once all fields are filled, click the “Calculate” button. The results will appear below, showing:
- Total Cost (including fees)
- Total Revenue
