Marketplace fee

Back Market, Amazon, Refurbed, eBay, and Rebuy all charge fees ranging from approximately 8% to 15% of transaction value, with variations by category and seller volume. Because fees directly reduce net margin, they must be factored into minimum acceptable resale prices and the maximum buyback offer a seller can afford to pay. Comparing gross prices across platforms without accounting for differing fee structures produces misleading margin assumptions.

Marketplace fees are not always straightforward to compare across platforms because fee structures differ in composition. Some platforms charge a simple percentage commission on the sale price. Others charge a listing fee in addition to a commission. Others offer tiered fee structures where higher-volume sellers pay lower rates. Understanding the all-in fee for each platform requires reviewing the specific fee schedule applicable to a seller's volume and category, not relying on headline rates that may reflect averages across all sellers.

Fee structure also interacts with returns policy in ways that affect total effective cost. On platforms that require the seller to cover return shipping and device re-inspection when a buyer returns a device, the return cost is an additional effective fee that does not appear in the platform's published commission rate. Operators who model margin based only on published commission and ignore return cost may find that actual per-unit economics are materially worse than projected, particularly in condition tiers with higher return rates.
