FBA Fees 2026: What's Changing and How It Will Affect Your Margins
David Grinberg1 min readAmazon is adjusting its FBA fee structure in Europe starting this year. We've calculated the impacts on typical product categories – some will benefit, others will significantly lose out.
Amazon adjusts its fee structure every year, and 2026 brings the biggest changes in the last three years. Here's an overview of the most important points for European sellers.
Key Changes at a Glance
- New dimensional categories for small and light products
- Storage price increase in Q4 by an average of 8%
- Lower fulfillment fees for products under 200g
- New low inventory turnover fee (aged inventory surcharge starting at 180 days)
Who Will Benefit
Sellers of small and light products under 200 grams will save money thanks to the expansion of the Small and Light program to additional categories. For a typical product costing €15, the fulfillment fee will decrease by €0.20–0.35.
Who Will Pay More
The greatest impact will be felt by sellers of seasonal goods who hold inventory for over 180 days. The new surcharge can reduce the margin of slow-moving goods by 2–4 percentage points.
Recommendation: review your inventory ledger and identify SKUs with inventory older than 150 days. A liquidation campaign in May will be cheaper than storage fees in Q4.
How to Calculate the Impact
Use the updated FBA Revenue Calculator directly in Seller Central. For a bulk recalculation of your entire catalog, we recommend exporting via SP-API or tools like Sellerboard.
What to Do This Month
- Recalculate margins for your top 20 SKUs with the new rates
- Check the dimensional classification of your products — errors in Amazon's measurements are common and can be disputed
- Set up automatic monitoring of aged inventory
