How Amazon FBA fees work in 2026

Referral is 15% in most categories, with a $0.30 minimum. Fulfillment for the smallest standard-size unit is $3.32 before fuel when the price is $10–$50, and $2.43 under $10, then a 3.5% fuel surcharge. Standard-size storage is $0.78 per cubic foot a month, and $2.40 in October through December. Peak fulfillment runs 15 Oct 2026–14 Jan 2027. On the $24.99 example, fulfillment is $4.35 outside that window and $4.65 inside it.

FBA or seller-fulfilled

FBA includes Amazon's pick, pack, and ship. Seller-fulfilled leaves that fee off and you pay the label. The Amazon revenue calculator compares both columns on one sale.

What this calculator leaves out

A Professional selling plan is $39.99 a month. An Individual plan is $0.99 a unit. Inbound placement, returns, aged inventory, and ads stay off until you turn them on. Apparel fulfillment and dangerous goods are not on this rate card. Seller Central is what Amazon bills.
