Selling on Amazon through Fulfillment by Amazon (FBA) opens doors to a massive reach, but understanding Amazon FBA fees is critical if you want to stay profitable in 2026. With Amazon refining its pricing structure year after year, sellers who don’t track costs closely often see margins quietly shrink. This guide breaks down every major cost you should expect and shows how smart sourcing and a low cost FPA prep solution(Amazon FBA prep service) can protect your bottom line.
Amazon’s fee system now rewards sellers who optimize packaging, storage duration, and inventory flow, while penalizing inefficiencies like oversized packaging or long-term storage.
Main Types of Amazon FBA Fees
Amazon FBA fees are split into key parts. Each one hits your bottom line. See the breakdown below.
Fulfillment Fees (Pick & Pack)
Fulfillment fees cover order handling, packing, and last-mile delivery. In 2026, FBA fees in this category are still based on:
- Product size tier (standard vs oversized)
- Shipping weight
- Dimensional weight (more important than ever)
Even small increases in package size can push you into a higher tier. This is where packaging optimization and a low cost FPA prep solution can save you significant money per unit.
Storage Fees: Monthly & Long-Term
Storage remains one of the most underestimated Amazon FBA fees. Amazon charges monthly storage fees based on volume (cubic feet), with higher rates during Q4 (October–December).
Additionally, long-term storage fees apply to inventory stored for over 180 days. In 2026, Amazon’s aging inventory surcharge makes slow-moving stock even more expensive, forcing sellers to plan inventory turns carefully.
Referral Fees
Amazon takes a share of each sale price. This includes item cost, shipping, and wrap fees. Rates run from 5% to 45%. Most categories hit 15%. For books, it’s 15%. Toys are 15% too. Baby items: 8% under $10, 15% over. Add a $0.30 minimum for many. No changes in 2025. Build this into your prices.
Returns & Removal Fees
The consumers still anticipate seamless returns in 2026, and Amazon implements a processing fee on returns for items such as apparel and footwear. Sellers can also incur the costs of removal or disposal of inventory in FBA warehouses.
In order to contain these incremental expenses, it is important to impose stringent quality assurance of the products prior to their delivery to Amazon. Consequently, numerous sellers prefer to use an inexpensive prep solution abroad to identify the defects at the initial stages and minimise the rate of returns prior to shipping.
Optional Service Fees
Amazon also offers paid services such as labeling, poly-bagging, bubble wrapping, and bundling. While optional, these services add to overall Amazon FBA fees if you don’t handle prep yourself.
This is where third-party prep services or sourcing partners become valuable.
