How Amazon FBA fees work in 2026
Amazon FBA fees have four layers, and most sellers only calculate two. Miss any of them and your margin projections are wrong before the first unit ships.
1. Referral fee — the biggest variable
Amazon's commission on every sale, calculated as a percentage of the total sale price including shipping. Most categories charge 15%, but the range runs from 6% (Personal Computers) to 45% (Amazon Device Accessories). The category traps that catch sellers: Clothing jumps from 5% to 17% at the $20 mark. Beauty and Health charge 8% under $10, 15% over. Electronics accessories (phone cases) are 15%, while Electronics (speakers) are 8%. Getting the category wrong by one tier can cut your margin in half.
2. FBA fulfillment fee — size and weight drive everything
Charged per unit when Amazon picks, packs, and ships your order. Determined by your product's size tier and weight. As of January 15, 2026, fees increased an average of $0.08/unit across most tiers. A 3.5% fuel and logistics surcharge was added April 17, 2026 on top of all fulfillment fees in the US and Canada. This averages ~$0.17 per unit on standard items.

3. Storage fees — the Q4 trap
Charged monthly for the cubic footage your inventory occupies in Amazon's fulfillment centers. Off-peak (January through September) runs $0.75/cu ft. Q4 (October through December) jumps to $2.25/cu ft — three times higher. A seller with 500 cubic feet of holiday inventory pays $1,125/month in Q4 vs $375 off-peak. Aged inventory surcharges kick in at 181 days ($0.30/unit at 12-15 months, $0.35/unit at 15+ months).
4. Inbound placement fee — avoidable but overlooked
Charged when you ship all inventory to one fulfillment center and Amazon redistributes it. Ranges from $0.14 to $1.90/unit for standard items depending on size and destination. Fully avoidable by shipping to 4+ fulfillment centers (Amazon-optimized), using AWD (Amazon Warehousing and Distribution), or splitting shipments across 2-3 FCs for a 40-70% reduction.
The real cost picture: On a $30 product in Home & Kitchen (15% category, 1.5 lb large standard): referral fee $4.50 + fulfillment fee $5.56 (with surcharge) = $10.06 in Amazon fees, 33.5% of revenue before COGS, shipping to Amazon, storage, or advertising.
FAQ
Total FBA costs typically run 25-40% of revenue for standard-size products priced $15-$50. The main components: referral fee (8-15% for most categories), FBA fulfillment fee ($3.17-$5.71 for most standard items after the fuel surcharge), storage ($0.75-$2.25/cu ft monthly depending on season), and optional inbound placement fees. Add your COGS, shipping to Amazon, and advertising on top.
Amazon added a 3.5% fuel and logistics surcharge to all FBA fulfillment fees effective April 17, 2026. It applies to every size tier in the US and Canada. For a large standard item at $5.52 base fulfillment, the surcharge adds $0.19/unit, making the actual fee $5.71. This calculator applies the surcharge automatically.
Most experienced FBA sellers target 20-30% net margin after all Amazon fees and COGS. Below 15% leaves almost no buffer for PPC, returns, or price competition. Above 30% is excellent. The calculator flags below 15% as a loss risk (red), 15-20% as tight (amber), and above 20% as healthy (green).
Ship to 4 or more Amazon fulfillment centers in the same shipment (Amazon-optimized routing) and the inbound placement fee drops to $0. Using Amazon Warehousing and Distribution (AWD) also eliminates the fee. If you can only ship to 1 location, the fee ranges from $0.14 to $1.90/unit for standard items.
Consumer Electronics, Computers, and Cameras charge 8% referral fees — one of the lowest rates on the platform. However, Electronics Accessories (phone cases, cables, screen protectors) are charged 15% — a completely different category. Getting this wrong costs significantly. This calculator has both categories as separate options.
