Amazon rolled out a broad set of fee increases for its Fulfillment by Amazon (FBA) program in early 2026, hitting sellers across multiple cost categories at once. The most visible change took effect on January 15, 2026, when fulfillment fees rose by an average of $0.08 per unit, following a full fee freeze in 2025.
That $0.08 average understates the real impact for many sellers. Small standard-size items priced between $10 and $50 saw increases of about $0.25 per unit. Products priced above $50 got hit hardest, with increases of $0.31 to $0.51 per unit. Amazon also introduced price-based tiers for the first time, splitting fees into brackets for items under $10, between $10 and $50, and over $50.
Inbound defect penalties jumped dramatically. Fees that ranged from $0.02 to $0.07 per unit in 2025 now run $0.32 to $1.74 for standard items and up to $5.72 for bulky products, according to Carbon6’s analysis. A single bad shipment with labeling or routing errors can now cost hundreds of dollars.
Amazon also ended its FBA prep and labeling services on January 1, 2026. Sellers who previously relied on Amazon to handle barcode labeling and packaging must now do it themselves or hire a third-party logistics provider. Shipments created after that date that arrive unprepped won’t be reimbursed if lost or damaged.
Starting March 12, 2026, Amazon shifted seller payouts to 7 days after delivery instead of after shipment. For most sellers, that adds roughly 7 to 14 days to the cash conversion cycle, which matters for managing inventory purchases and operating expenses.
On the software side, Amazon announced in November 2025 that it would begin charging third-party developers $1,400 per year for Selling Partner API access, with usage-based fees starting April 30, 2026. However, according to Amazon’s official developer page, the company has since delayed this fee rollout and will share updated timelines in the fall. Sellers using third-party tools should still budget for potential price increases from their software providers once the fees do take effect.
For small businesses selling on Amazon, the practical step right now is to recalculate product-level profitability using the 2026 fee schedule. Sellers with items priced near the $50 threshold, high return rates, or thin margins should review whether FBA still makes sense for every SKU, or whether a hybrid fulfillment approach could reduce costs.
