Know the most you can pay before you source the item.
Enter an expected sale price, choose a marketplace, add shipping and fulfillment costs, and set a target profit. The calculator solves the maximum affordable item cost.
Built for sourcing decisions
The calculator first estimates net proceeds after marketplace and selling costs. It then subtracts the target profit and rounds down to the highest affordable cent.
Keep the sale-price assumption realistic
The result depends on the expected sale price you enter. It does not use sold listings, demand data, item condition, or sell-through estimates.
Marketplace fees change and vary. Results are estimates, not tax or accounting advice.
