FBA fulfillment fees are per-unit charges Amazon assesses for picking, packing, and shipping your products to customers. They vary based on product size tier (standard vs oversize) and shipping weight.
Fees are based on size tier classification and shipping weight. Amazon measures your product dimensions, applies dimensional weight if applicable, and charges the corresponding rate from their fee schedule.
Dimensional weight is calculated as (Length × Width × Height) ÷ 139 for units over 1 lb. Amazon charges based on the greater of actual weight or dimensional weight.
Reduce fees by optimizing packaging to stay within smaller size tiers, reducing product weight, using manufacturer packaging that fits standard-size requirements, and regularly auditing your size tier classifications.
Amazon typically updates FBA fulfillment fees annually, usually effective in January or February. They announce changes several months in advance so sellers can adjust pricing and profitability models.
Track every fee, calculate true profit per unit, and never guess your margins again.
