Amazon FBA’s Hidden Fees in 2025: Don’t Let These Kill Your Profits

Amazon FBA (Fulfillment by Amazon) is an incredibly powerful tool for e-commerce sellers, leveraging Amazon’s vast logistics network to handle storage, packing, and shipping. However, many sellers overlook the hidden fees that can significantly eat into their profits, especially as Amazon refines its fee structures in 2025. Understanding these fees and knowing how to manage them can make the difference between a profitable and struggling Amazon business.

Let’s dive into the most critical FBA fees in 2025 and explore how Seller Labs’ tools can help you reduce these costs and protect your margins.

1. FBA Storage Fees: More Than Meets the Eye

Amazon charges sellers for storing their products in FBA warehouses, but the cost depends on how well you manage your stock. Fees can spike during peak seasons, and long-term storage fees are now harsher than ever.

• Standard Storage Fees: These vary by season, with rates increasing during peak months (October–December).
• Long-Term Storage Fees: If your inventory sits for more than 181 days, Amazon applies a surcharge.
• Aged Inventory Surcharge:
  • 181–270 days: $1.50 per cubic foot
  • 271–365 days: $3.80 per cubic foot
  • 365+ days: $6.90 per unit (not just per cubic foot)

2. FBA Inbound Placement Service Fees: The Hidden Cost of Shipment Splits

When you ship your inventory to Amazon, you may face additional costs if your shipment is split across multiple fulfillment centers. The cost varies depending on the size and weight of the items.

• Fees: $0.27–$1.58 per unit, based on item dimensions and weight.

3. Returns Processing Fees: Handling the Inevitable

Returns are inevitable, but Amazon now charges per-unit return processing fees, especially for high-return categories like apparel and electronics. The fee ranges from $2.12 to $6.85 per unit, and items returned may be sent for liquidation or disposal.

4. Unplanned Service Fees: Amazon’s Strict Compliance Costs

Amazon charges additional fees for errors in labeling, packaging, and shipment preparation. Unplanned Service Fees can arise from:

• Mislabeling: If your products are not correctly labeled, Amazon will apply a fee to fix the issue.
• Improper Packaging: Items requiring bagging or bubble wrapping incur additional fees.

5. ACoS Drain from Ad Waste: Keep Your Ads Efficient

While not technically an FBA fee, Advertising Cost of Sale (ACoS) can significantly drain your profits if not managed carefully. Wasted ad spend from running campaigns during off-peak hours or targeting ineffective keywords can lead to higher costs without corresponding sales.

6. Removal & Disposal Fees: The Silent Profit Killer

If you have excess or unsellable inventory, Amazon offers two costly options:

1. Removal Orders – Amazon ships the items back to you at a fee per unit.
2. Disposal Orders – Amazon destroys unsold inventory (also at a per-unit cost).

2025 Update: Amazon has increased removal fees by 20% to discourage overstocking, making it essential to plan inventory more efficiently.

7. Returns & Refund Fees: Hidden Deductions Impacting Profits

Amazon’s return policy often leaves sellers footing the bill. When items are returned, you may not recover the full referral fee, and if the product is deemed unsellable, additional fees apply.

• Restocking Fees: Amazon deducts up to 50% of the item’s price when issuing customer refunds.
• Return Processing Fees: If a product is returned and deemed unsellable, Amazon may charge additional disposal fees.

8. FBA Fee Changes in 2025: What’s New?

Amazon’s FBA fees are always evolving, and 2025 is no exception. Sellers should be prepared for:

• Increased Dimensional Weight Pricing: Bulky items now incur higher fees.
• Expanded Peak Season Charges: Higher costs during the holiday season.
• Higher Small & Light Program Fees: Reevaluate pricing strategies for small and light products.
