Amazon FBA Fee Changes in 2025: What Sellers Need to Know

Every January, Amazon adjusts its FBA fee structure, and every January, sellers scramble to figure out what it means for their margins. The amazon fba fees 2025 update is no different, but this year's changes are more nuanced than a simple rate hike. Some product categories are seeing decreases. Others are getting squeezed harder than ever.

Here's what actually changed and what to do about it.

The Big Changes to Amazon FBA Fees in 2025

Fulfillment Fee Adjustments

Amazon reduced base fulfillment fees by an average of $0.17 per unit for standard-size items. Sounds like good news, right? It is, for small, lightweight products. A 6 oz item that cost $3.22 to fulfill in 2024 now costs roughly $3.06.

But here's the catch. Amazon simultaneously restructured size tiers and weight thresholds. Products that previously sat at the top of one tier may now fall into the bottom of the next tier up. We've seen products jump from $3.06 to $4.75 overnight because of a size tier reclassification. Measure your packaging carefully.

Inbound Placement Fees

This is the biggest pain point of 2025. Amazon now charges inbound placement fees for sellers who ship inventory to a single fulfillment center instead of distributing across the network. The fee ranges from $0.21 to $1.58 per unit depending on size.

You can avoid this fee by using Amazon's inventory placement options that distribute your shipments across multiple warehouses. But that means higher shipping costs on your end. Run the math both ways. For many sellers, splitting shipments is still cheaper.

Low-Inventory-Level Fees

New for 2025: Amazon charges a fee when your historical inventory levels are consistently low relative to your sales velocity. The threshold is roughly 28 days of supply. If your FBA inventory regularly dips below 4 weeks of stock, you'll pay an additional $0.32-$0.63 per unit sold.

This is Amazon's way of pushing sellers to keep warehouses stocked. It directly conflicts with the aged inventory surcharges that penalize you for keeping too much stock. The sweet spot is now a narrow 28-60 day window.

Amazon FBA Fees 2025: Category-Specific Impacts

• Small, lightweight items (under 1 lb): Net decrease of 2-5%. These sellers benefit most from the base rate reduction.
• Mid-size items (1-3 lbs): Roughly flat. Base fee decrease offset by inbound placement costs.
• Large/heavy items (3+ lbs): Net increase of 5-12%. Size tier reclassifications and inbound fees hit these hardest.
• Apparel: Slight increase. Amazon applied category-specific adjustments that added $0.10-$0.30 per unit.

How to Adjust Your Strategy

Repackage where possible. If your product is within half an inch of a size tier boundary, redesigning your packaging to fit the smaller tier can save $1.00+ per unit. At 10,000 units a month, that's $120,000 a year.

Rethink your FBA vs. FBM mix. For large or heavy items, Fulfilled by Merchant may now be cheaper. Run a side-by-side cost comparison for every SKU above 3 lbs.

Fix your inventory planning. The low-inventory-level fee makes stockouts more expensive than ever. Invest in demand forecasting tools or work with a partner who manages this for you. The margin between too little and too much inventory just got thinner.

Optimize inbound shipments. Use Amazon's Send to Amazon workflow with distributed placement to avoid inbound fees. Yes, it's more operationally complex. But the per-unit savings add up quickly on high-volume SKUs.

Audit your catalog profitability. Some SKUs that were marginally profitable in 2024 are now underwater. Better to cut them proactively than to bleed cash for months before noticing.

Fee changes are a constant on Amazon. The sellers who win aren't the ones who complain about it; they're the ones who model the impact, adjust fast, and keep their unit economics tight. If you need help running those numbers, our operations team manages this process for every brand in our portfolio.
