Overview

Amazon will roll out a revamped FBA fee schedule for U.S. sellers on January 1 2026. The average per‑unit increase is about eight cents, but the new model ties fees to product size, weight, and selling price, creating distinct winners and losers across catalog mixes. Sellers who examine the details now can protect margins and avoid surprise cost spikes.

Key Points

• Weight‑based bands — Large standard‑size items are now split into five weight brackets ranging from 3 lb to 20 lb, while small standard items have two brackets, replacing the single‑band system used through 2025.
• Price‑tiered fees — Within each size class, Amazon applies three price tiers: under $10, $10‑$25, and over $25, a first for FBA fees that directly links selling price to the charge.
• Restructured size categories — The former “bulky” classification is divided, allowing products just over 3 lb to fall into a lower‑rate tier if they meet the new criteria.
• Overmax handling surcharge — Items whose longest side exceeds 96 inches or whose length‑plus‑girth surpasses 130 inches incur an extra fee ranging from $2 to $25 per unit.
• Low‑price discount boost — Items priced under $10 now receive a $0.86 discount below the standard rate, up from a $0.77 discount in 2025.
• Higher inbound placement fees — Multi‑split inbound fees for standard‑size units rise by an average of $0.05, and minimal‑split fees increase $0.27 per unit.

How the New Fee Structure Works

1. Determine size and weight band — A 4 lb, 12‑inch tall kitchen gadget is classified as large standard‑size and placed in the 3‑5 lb weight band; a 0.8 lb, 6‑inch book stays in the small standard‑size, low‑weight band.
2. Apply price tier — If the kitchen gadget sells for $28, it falls into the “over $25” price tier and receives the highest per‑unit fee for its band; the book priced at $9 lands in the “under $10” tier and benefits from the enhanced discount.
3. Add any surcharge — A 100‑inch‑long garden hose exceeds the 96‑inch limit, so Amazon adds a $5 handling surcharge on top of the base fee calculated from steps 1 and 2.
