Online Seller Profit Calculator

Sold it. But what did you actually keep?

Check your selling price before you accept an offer. This Excel calculator helps online sellers see estimated profit after item costs, postage, packaging and selling fees.

What you can check

• Estimated profit on a sale
• Your break-even item price
• The item price needed to reach your target profit

Enter your own sale price, postage charged, item cost, postage paid, packaging costs, marketplace fee, advertising fee, fixed fee and target profit. Both percentage fees apply to the item price plus postage charged.

What you receive

One downloadable Microsoft Excel (.xlsx) workbook for A$2.50 AUD. One-off purchase. No Just One Tab subscription. Microsoft Excel is required and is not included. No physical item is shipped. A native Google Sheets copy is not included.

Fictional example: A$65 item price plus A$8 postage charged, less A$48.98 in entered costs and fees, leaves A$24.02 estimated profit. Results depend on your inputs and include only the costs you enter. Use a consistent GST basis.
