What changed for Amazon FBA fees in 2026 and why it matters
Amazon introduced fee changes after a relatively stable period, with modest fee increases across several areas. Many updates begin starting january 15 2026 for US sellers. Amazon positions these moves as efforts to provide enhanced services across its fulfillment centers and to support faster delivery promises and convenient delivery.
One headline many sellers discuss is an average fulfillment fee increase often summarized as 0.08 per unit. Some announcements also describe 0.08 per unit sold. Even when it sounds small, it compounds quickly once you scale.
The key takeaway is simple. Rebuild your model around amazon’s fee structure and the full set of underlying costs. If you only track one fee change, you will miss where profit margins are really leaking.
The full Amazon fee structure sellers must track in 2026
To understand Amazon FBA fee increases in 2026, focus on the full fee structure, not a single number. Most sellers lose margin when they only watch fulfillment fees and forget the other cost layers that hit every unit sold.
In 2026, Amazon’s fee structure usually falls into six cost areas. This keeps the model simple and makes it easier to compare SKUs.
| Cost area | What it includes | How it is charged |
|---|---|---|
| Referral fees | US referral fees by category | Percent of selling price |
| Fulfillment fees | Pick pack ship and support | Per unit by size tier shipping weight |
| Storage fees | Monthly storage fees | Per cubic foot per month |
| Inbound fees | Shipping costs, inventory placement, inbound defect fees | Per shipment and per unit |
| Inventory penalties | Aged inventory surcharges, low inventory level fees | Triggered by age or inventory levels |
| Cleanup and loss | Removal and disposal fees, missing and damaged inventory | Per unit and adjustments |
Amazon may describe some updates as new FBA fee types, but the best approach stays the same. Track these six areas per unit and per unit sold, then adjust pricing, packaging, and inventory levels based on the SKUs that are most sensitive to fee changes.
Fulfillment fees in 2026 what drives the changes
For most Amazon sellers, FBA fulfillment fees are the largest and most visible cost line. In 2026, fulfillment fee changes are driven mainly by size tier shipping weight and your product price point. A small shift in packaged dimensions or shipping weight can move a SKU into a different tier and change the fee you pay per unit.
Amazon links many fee changes to investments inside fulfillment centers and the wider delivery network. The goal is to support faster delivery promises, reduce bottlenecks, and maintain convenient delivery during peak demand. When the network is under pressure, fees tend to rise on SKUs that take more space, require more handling, or create higher operational complexity.
The impact is not uniform. Some listings see higher fees, especially in competitive categories with strong customer demand. Others may see lower fees when Amazon reshapes capacity and adjusts tiers to better match processing costs.
Two practical reminders protect profit margins.
Always calculate fulfillment fees per unit, not per shipment
Compare fee changes by average item selling price and packaging tier
If you only look at averages, you risk missing how your SKU mix is affected and where small packaging improvements can unlock lower fees.
US referral fees and how to model them correctly
Referral fees are the second core component of amazon fees. US referral rates vary by category, and the fee rates range can be wide.
A simple rule helps you model correctly:
Treat US referral fees as a separate cost line
Do not mix referral fees into fulfillment fees
Recheck referral rates after category or listing changes
If you sell in categories with high referral fees, your pricing power must be stronger. Otherwise, small fulfillment fee increases can tip your profit margins into the red.
Storage fees, monthly storage fees, and aged inventory surcharges
Storage fees are where many sellers get surprised. Monthly storage fees may look manageable, but they compound when inventory sits. Monthly storage fees are typically charged per cubic foot, so bulky packaging can raise costs even if unit weight is low.
Aged inventory surcharges are another major driver. If you carry excess inventory, you risk stacked penalties that can become material financial penalties over time.
To protect margins in 2026
Measure unit volume accurately and optimize per cubic foot usage
Reduce over sending that creates excess inventory
Build a plan for aged inventory surcharges before inventory becomes old
Amazon’s direction is clear. They want faster turnover and healthier inventory levels. Sellers who ignore inventory age often end up paying higher fees, plus removal and disposal fees later.
Low inventory level fees and maintaining healthy inventory levels
Low inventory level fees exist to discourage frequent stockouts and unstable replenishment. These fees connect to inventory levels and how often Amazon sees your listing run low.
Low stock can also lead to slower delivery promises, which hurts conversion. Amazon wants stable availability to protect customer demand and maintain fast shipping promises.
Maintaining healthy inventory levels means balance:
Too low, and you risk low inventory level fees plus slower delivery promises
Too high, and you pay storage fees, aged inventory surcharges, and disposal fees
Healthy inventory levels are built with forecasting, not hope. If you want predictable profit margins, track inventory levels weekly and tie replenishment to sell through.
Inbound shipping costs, inventory placement, and inbound defect fees
Inbound shipping is now a major part of total amazon fba fees. In 2026, sellers need to model shipping costs plus placement decisions.
Inventory placement decisions
Inventory placement can reduce operational complexity by sending stock to fewer locations. It may also add a per unit charge depending on the option you choose.
Some sellers choose placement to simplify inbound ops. Others accept splits to achieve lower fee options.
Both approaches can work. What matters is your cost model and your team capacity.
Inbound defect fees and defect fees
Inbound defect fees are tied to inbound performance and compliance. Sellers also describe these as defect fees, especially when penalties are consolidated.
Some updates refer to a single inbound defect fee that replaces multiple older penalties. A single inbound defect fee can make cost forecasting easier, but it also makes mistakes more expensive.
Other major US carriers
If you ship inbound using other major us carriers, carrier consistency matters. Switching carriers often can raise defect risk, cause appointment issues, and increase inbound defect fees.
AWD transportation fees
Some sellers use upstream storage programs and compare awd transportation fees with their 3PL or direct inbound approach. AWD transportation fees can help in some cases, but only if total cost per unit improves.
Inbound is not just a logistics topic. It is a profit topic.
Removal and disposal fees, plus missing and damaged inventory
When inventory is slow or unsellable, removals and disposal become unavoidable.
Removal and disposal fees should be part of your SKU plan from day one, especially for seasonal items. Disposal fees are not only a last resort. They are a risk control tool.
To reduce removal and disposal fees:
Identify slow SKUs early and avoid sending too much stock
Use price actions before inventory ages into higher penalties
Plan removals earlier to avoid stacked storage fees and aged inventory surcharges
Some sellers look for policies that provide faster removals processing because it reduces the time inventory stays in fee heavy status.
Also track missing and damaged inventory. Missing and damaged inventory affects net available units and real profit analytics. Damaged inventory can also trigger extra costs through returns, liquidation, and write offs.
Other 2026 changes that affect cash flow and real costs
Not all fee changes show up as a clean line in your calculator. Some changes hit your operations and cash flow.
FBA prep services
If you relied on FBA prep services, shift to supplier prep or a 3PL. Prep changes can raise costs, increase lead time, and impact inbound quality.
Payout timing and cash flow
Any payout timing shift affects working capital. It does not change gross margin directly, but it changes cash flow, especially for fast scaling sellers.
Service level pressure
Amazon invests in delivery promises. Faster delivery promises can improve conversion, but they can also raise network costs, which often shows up as fee increases. In competitive categories, rising costs and rising ad costs can compress profit margins faster than the average fulfillment fee increase alone.

Confirm results with the revenue calculator and the fee preview report, then track each SKU in a profit analytics dashboard.
How to achieve lower fee options and lower FBA fees in 2026
Sellers who win in 2026 focus on controllable levers. The goal is lower fees without losing conversion.
Product packaging and size tier optimization
Product packaging is one of the fastest ways to reduce fulfillment fees. Packaging affects size tier shipping weight, which drives many fulfillment fee changes.
Actions that often reduce costs:
Reduce outer dimensions with tighter packaging
Remove unnecessary fillers and oversized cartons
Measure again to avoid incorrect tier assignment
Improve protection to reduce damaged inventory and returns
Inventory strategy that protects margins
To reduce storage fees and aged inventory surcharges.
Ship smaller batches more often
Set reorder points based on inventory levels and sell through
Avoid excess inventory that triggers higher fees later
Reduce defect fees through inbound SOPs
Inbound defect fees are often avoidable.
Standardize labels, cartons, and documentation
Book appointments correctly and avoid late deliveries
Keep carrier selection stable and reliable
Pricing and average item selling price strategy
Many sellers adjust pricing to cover fee increases. Test price elasticity, bundling, or multipacks, especially if your average item selling price is under pressure. Low price FBA may help when your price point is under 10, but it is not a complete solution without packaging and inbound control.
