Amazon FBA Fees Breakdown 2026: What You Actually Pay Per Unit
Complete breakdown of Amazon FBA fees in 2026: fulfillment fees by size tier, storage fees, referral fees, and how to calculate your true cost per unit sold.
The Three Main FBA Fee Categories
Amazon FBA fees fall into three buckets: fulfillment fees (picking, packing, shipping per unit), storage fees (monthly fee per cubic foot of inventory in Amazon's warehouse), and referral fees (Amazon's commission per sale, separate from FBA). Understanding all three is essential for accurate margin calculations. Many new sellers only account for fulfillment fees and are surprised by storage and referral costs.
FBA Fulfillment Fees 2026
Fulfillment fees are charged per unit shipped and depend on the product's size tier and weight. Small standard (under 1 lb): approximately $3.22 per unit. Large standard (1-3 lb): approximately $4.45-5.40 per unit depending on exact weight. Large standard (3-20 lb): $6.35 + $0.22 per additional pound. Large bulky (up to 50 lb): $9.73 + $0.42 per additional pound. Extra-large items: higher fees scale with weight. These are 2026 baseline rates -- Amazon adjusts fees annually and adds seasonal surcharges during peak periods (October-January).
Monthly Storage Fees
Storage fees are charged on the monthly average volume of inventory in Amazon's fulfillment centers, measured in cubic feet. January-September: $0.78 per cubic foot for standard-size. October-December (peak): $2.40 per cubic foot. Oversized: $0.56 per cubic foot (Jan-Sep), $1.40 (Oct-Dec). High-age inventory surcharge: products stored over 365 days incur additional fees. Avoid excess inventory accumulation, especially heading into Q4 when standard storage rates triple.
Referral Fees
Referral fees are Amazon's commission and are NOT part of FBA -- they apply to all Amazon sales whether fulfilled by Amazon or by the seller. Most categories: 8-15% of the total sale price (including shipping). Electronics: typically 8%. Clothing and accessories: 17%. Jewelry: 20% up to $250, 5% above. Amazon devices and accessories: 45%. Always check the category-specific referral fee before launching in a new category -- some categories make margin nearly impossible for low-price items.
Calculating True Landed Cost
True margin = Sale price minus referral fee minus FBA fulfillment fee minus monthly storage allocation minus product cost minus inbound shipping to Amazon. Example: $30 product. Referral fee (15%): $4.50. FBA fee (small standard): $3.22. Storage allocation (~$0.30/unit at moderate inventory levels). Product cost: $8. Inbound shipping: $1. Total costs: $17.02. Gross margin: $12.98 (43%). This is before advertising spend, which for competitive categories often runs 10-25% of revenue. Net margins of 15-25% are considered healthy for FBA businesses.
