The 2026 FBA fee changes compress ungated wholesale margins mainly through higher per-unit fulfillment costs and tighter penalties for poor inventory management. Standard-size products priced between $10–$50 (typical for many ungated grocery, health, and home items) see per-unit increases that can shave 2–3 percentage points off net margin if you keep prices constant—for example, a product at a 25% margin can drop to roughly 22% simply from the added fulfillment cost.
Low-inventory-level fees now apply at the individual FNSKU level, which disproportionately affects slow-moving SKUs such as certain Office Supplies, niche Home & Kitchen items, or poorly chosen bundles. If your days of cover fall below Amazon’s threshold, you pay an extra per-unit fee on every sale, turning marginally profitable SKUs unprofitable unless you either raise prices or improve sell-through.
Prioritize fast-moving SKUs and cut long-tail experiments.
Use bundling or multipacks to push offers into higher price bands where the fee increase is smaller relative to selling price.
Model all offers in Amazon’s revenue/profit calculators with 2026 rates before sending inventory, so you can reprice or drop SKUs that fall below your target 20–30% net margin range.
