Referral fee + FBA fulfillment + storage · 2026
Referral fees per Amazon's US schedule (checked September 2026). Get your exact FBA fee from Amazon's Revenue Calculator — it depends on size, weight and price, plus a 3.5% fuel surcharge since April 17, 2026.
Amazon FBA represents one of the more complex fee structures among major selling platforms, layering referral fees, fulfillment charges, and storage costs in ways that aren't always intuitive until you've sold through a full inventory cycle. The trade-off for this complexity is access to Prime-eligible shipping and Amazon's logistics network — a combination that can meaningfully boost conversion rates for the right products, provided the fees are properly accounted for in your pricing from day one.
Amazon's referral fee is 15% in most categories — including Home & Kitchen, Toys & Games, and Sports — but drops to 8% for Consumer Electronics and Computers, and uses price tiers in others. Clothing pays 5% on items up to $15, 10% from $15.01 to $20, and 17% above $20, applied to the whole price. Jewelry pays 20% on the first $250 and 5% on the rest. A $40 item in Computers pays $3.20; the same price in Jewelry pays $8.00 — a $4.80 difference that, multiplied across hundreds of units, can decide whether a product line is viable. Most categories also have a $0.30 minimum referral fee.
Consider a kitchen gadget priced at $25 in Home & Kitchen, which pays the standard 15% referral fee: $3.75. Suppose Amazon's Revenue Calculator shows a $4.50 FBA fulfillment fee for its size and weight, and you budget $0.15 per unit for storage. Total Amazon fees come to $8.40 — about a third of the sale price. If your product cost (manufacturing plus shipping to Amazon's warehouse) is $7, your profit is $9.60, a 38% margin once all platform costs are accounted for. Enter your own FBA fee in the calculator above: since January 15, 2026, Amazon's fulfillment fee depends on size tier, shipping weight, and the item's price band, and a 3.5% fuel and logistics surcharge has applied since April 17, 2026.
Two storage-related charges catch many new FBA sellers off guard. First, Amazon's monthly storage fee, charged per cubic foot, is substantially higher during the October–December peak season, reflecting the warehouse space premium during the holiday shopping surge. Second, inventory that sits unsold for too long incurs aged-inventory surcharges — a penalty designed to discourage sellers from using Amazon's warehouses as long-term storage for slow-moving stock. Check Amazon's current storage fee page for the rates that apply to your size tier. Both of these costs are entirely avoidable with proactive inventory management, but they can significantly erode margins for sellers who don't actively monitor their sell-through rate.
The formula that matters most for any FBA seller is straightforward in concept but easy to get wrong in practice: Profit = Sale Price − Referral Fee − FBA Fulfillment Fee − Storage Fee − Product Cost − Inbound Shipping. Many new sellers calculate margin using only product cost against sale price, entirely omitting Amazon's fees from the equation — a mistake that can make an apparently profitable product line actually break even or lose money once the full fee structure is applied. Our calculator above handles this complete calculation automatically, but understanding each component helps you make sourcing and pricing decisions before you've committed to inventory.
For most product categories, the Prime badge and associated trust significantly increase conversion rates compared to standalone e-commerce, often enough to offset Amazon's higher fees compared to platforms like Shopify or Etsy. The calculation tends to favor FBA most clearly for products with reasonable margins and consistent demand — thin-margin products or highly seasonal items deserve more careful modeling before committing to FBA's fee structure at scale.
