Comic & Card Reseller Profit Calculator

Know your profit before you sell.

Selling a comic or trading card involves more than the sale price. The Simpleman’s Comics Reseller Profit Calculator helps you estimate what you’ll keep after purchase costs, grading, selling fees, shipping, and packing supplies.

Enter your numbers in the highlighted cells to calculate:

• Estimated profit after your entered costs.

• Profit margin on the sale.

• Break-even item price to cover your costs.

• Minimum offer price to reach your target profit.

Made for comics, cards, and bundles

Use it for an individual collectible or enter combined costs for an entire bundle. Adjustable inputs include percentage fees, fixed order fees, buyer-paid shipping, and fees on sales tax.

What’s included

• Editable Excel profit calculator (.xlsx).

• Two-page PDF Quick Start with instructions and a worked example.

Open the workbook in Microsoft Excel, replace the sample inputs with your own figures, and review your results. Save a separate copy for each item or bundle.
