Amazon FBA Fee Structure (2026)

Amazon charges three main fees for FBA sellers. Fulfillment rates below are the 2026 schedule effective January 15, 2026, plus the 3.5% fuel surcharge added April 17, 2026.

Referral Fee (8%–17%): A percentage of the selling price based on product category. Beauty, Health & Household, and Grocery charge 8% at or below $10 and 15% above $10. Minimum $0.30 per unit even on low-priced items.
FBA Fulfillment Fee: A per-unit fee for picking, packing, and shipping. In 2026 it varies by size tier, weight, and selling price band (under $10, $10–$50, over $50). A 3.5% fuel & logistics surcharge is layered on top since April 17, 2026.
Monthly Storage Fee: Charged per cubic foot of warehouse space. $0.78/cu ft standard (Jan–Sep) and $2.40/cu ft peak (Oct–Dec). Aged inventory over 12 months incurs additional surcharges.
