Amazon's FBA fee structure has changed again in 2026. Anyone who wants to protect their margins and sell profitably on Amazon must understand the current cost structure precisely. In this post, we break down all relevant fees and show concrete optimization levers that we use in practice with our clients.
The Three Fee Pillars of Amazon FBA
Amazon FBA costs consist of three main components: Referral Fees, FBA Fulfillment Fees, and Storage Fees. Additionally, there are situation-dependent extra costs. Each pillar has its own calculation basis and optimization potential.
1. Referral Fees
The referral fee is the commission Amazon charges for every sale. It ranges from 7% to 15% of the selling price, depending on the category. The key rates for 2026:
- Electronics & Computers: 7-8%
- Clothing & Shoes: 15% (under 45 euros) or 7% (from 45 euros for shoes)
- Home & Garden: 15%
- Beauty & Personal Care: 8-15% (tiered by price)
- Grocery: 8-15%
- Toys & Games: 15%
Additionally, a minimum referral fee of 0.30 euros per item applies. For low-priced products under 3 euros, this can push the effective fee above 10%.
2. FBA Fulfillment Fees
FBA fulfillment fees cover picking, packing, and shipping to the end customer. They are calculated by the size and weight of the ready-to-ship package. Current tiers for standard products on Amazon.de:
- Small envelope (up to 80g): from 1.87 euros
- Standard size (up to 400g): from 2.87 euros
- Standard size (up to 900g): from 3.61 euros
- Standard size (up to 1.5kg): from 4.39 euros
- Oversize (up to 5kg): from 6.22 euros
- Oversize (up to 10kg): from 7.05 euros
In 2026, Amazon further refined fee categories. The introduction of the "Low Inventory Level Fee" means sellers with chronically low inventory levels (under 28 days of coverage) pay a surcharge. At the same time, Amazon integrated the Small and Light program into the regular fee structure, leading to slightly reduced rates for products under 12 euros.
3. Storage Fees
Amazon charges monthly storage fees based on the volume of your stored goods. Rates differ significantly between peak and off-peak season:
- January to September: approx. 30.60 euros per cubic meter/month (standard)
- October to December: approx. 42.37 euros per cubic meter/month (standard)
- Oversize January-September: approx. 18.36 euros per cubic meter/month
- Oversize October-December: approx. 25.34 euros per cubic meter/month
Additionally, aged inventory surcharges apply: goods stored longer than 181 days incur extra fees. From 271 days and especially from 365 days, costs increase significantly. The aged inventory surcharge can reach up to 6.90 euros per cubic meter.
Hidden Costs Often Overlooked
Beyond the three main fee types, other cost items should be part of every calculation:
- Removal & Disposal Fees: 0.25-1.20 euros per unit for removing or disposing of inventory
- Return Processing Fees: For certain categories (e.g., clothing), Amazon charges additional return fees
- Prep Service Fees: If Amazon needs to label or repackage your products, per-unit charges apply
- Inbound Placement Fee: Reinforced in 2026, charged when you specify which warehouse receives your shipment instead of letting Amazon distribute
How to Optimize Your FBA Costs
From our experience with over 50 Amazon accounts, these are the most effective levers:
- Optimize packaging: Every centimeter counts. Reduce package size to the minimum and move into a cheaper size tier. Switching from "Standard" to "Small envelope" can save 1 euro per unit
- Keep IPI score above 500: A good Inventory Performance Index avoids storage limits and extra fees. Rule: proactively remove goods that do not sell within 90 days
- Plan seasonal storage: Q4 storage fees are 38% higher. Time your replenishment so you have sufficient stock in October without excess inventory during the premium-price period
- Avoid Low Inventory Level Fee: Maintain at least 28 days of inventory coverage to avoid the new surcharge. Set up automatic reorder alerts in Seller Central
- Create product bundles: Instead of shipping individual low-priced items, combine multiple products into one bundle. This significantly reduces FBA fees per sales unit
Sample Calculation: What Remains?
Take a typical product: selling price 29.99 euros, Home & Garden category, standard size 400g.
- Referral Fee (15%): 4.50 euros
- FBA Fulfillment Fee: 2.87 euros
- Storage Fee (prorated per unit): approx. 0.15 euros
- Total Amazon Fees: approx. 7.52 euros (25.1% of selling price)
With a cost of goods of 8 euros and advertising costs of 3.50 euros (ACOS around 23%), you retain 10.97 euros in gross profit. That corresponds to a net margin of approximately 36.6% before taxes and fixed costs. This is solid, but it shows: anyone who does not manage their Amazon costs risks burning through margin quickly.
Conclusion: Know Your Fees, Protect Your Margins
The FBA fee structure in 2026 is more complex than ever, but also more calculable. Use the Amazon Revenue Calculator for every product calculation, review your cost structure quarterly, and proactively optimize packaging sizes and inventory levels. Those who know their numbers make better decisions and build a sustainably profitable Amazon business.
