Works out your size tier, billable weight, fulfilment fee, the 3.5% fuel surcharge and referral fee — then shows what is left per unit. Updated for the 2026 price-band structure introduced on 15 January.
Measure the unit as it ships. Size tier and billable weight are worked out for you.
Rates reflect the published US 2026 rate card, including the January price bands and the 3.5% fuel and logistics surcharge effective 17 April 2026. Apparel, dangerous goods, Low-Price FBA and the Overmax surcharge follow separate ladders. Confirm your exact figure in Seller Central’s Fee Preview before pricing decisions.
Fulfilment fees are published in three price bands — under $10, $10 to $50, and over $50. The same product at a higher price point pays a higher fulfilment fee. The January increases ranged from roughly $0.12 per unit in the lowest band to $0.51 in the highest.
A 3.5% fuel and logistics surcharge applies on top of every fulfilment fee from 17 April 2026. It is calculated on the fee rather than the sale price, and it does not apply to storage or referral fees.
Measurement errors and misclassified size tiers are recoverable inside Amazon’s claim windows. The free audit checks your fee preview against your real dimensions across the catalogue.
