Amazon’s 2026 FBA Fee Changes: What Sellers Need to Know

Amazon’s 2026 fee structure is now live, and it’s more nuanced than ever. Here’s what sellers need to know:

Effective January 15, 2026, FBA fees increased by an average of $0.08 per unit—less than 0.5% of an average item’s selling price. But the real story is in the details.

The Fee Changes Are Tiered by Price Point and Product Size

• Standard-size items $10-$50: Small items up $0.25/unit, Large items up $0.05/unit
• Items below $10: Small items up $0.12/unit (but with increased discounts)
• Items above $50: Small items up $0.51/unit, Large items up $0.31/unit
• Low-inventory-level fees now apply at FNSKU level (not parent-ASIN), which means better inventory management is critical
• Aged inventory fees increased: items 12-15 months old now cost $0.30/unit/month (up from $0.15)
• New tier: items over 15 months cost $0.35/unit/month
• Bulky and Extra-Large items saw restructuring—some decreases, some increases depending on packaging

Why This Matters

Amazon is rewarding sellers who maintain healthy inventory levels and optimize their operations. The shift from parent-ASIN to FNSKU-level fees means you need to track each variation closely. Slow-moving inventory is now significantly more expensive to hold.

What to Do Now

• Audit your inventory age—especially items approaching the 12-month mark
• Use the Revenue Calculator and Profit Analytics dashboard to see how these changes impact each product
• Consider removing or liquidating slow movers before fees compound
• Optimize your packaging and inbound shipment options to reduce placement fees
• Review your pricing strategy to ensure margins still work with the new fee structure
