How the calculator works
- Marketplace fees are calculated as a percentage of the expected sale price.
- Net profit subtracts purchase, fees, shipping, packaging, cleaning, and restoration.
- Return on purchase compares net profit with the original purchase price.
- Break-even price is the minimum sale price needed to cover the entered costs and percentage fee.
Costs resellers often miss
Leave room for payment processing, promoted-listing fees, returns, insurance, sales tax rules, travel, storage, and your labor. Fragile or oversized antiques may also require specialist packing. Use completed comparable sales—not asking prices—when estimating a realistic resale price.
