Quick answer: Amazon FBA sellers in 2026 should model the full cost stack: referral fees, FBA fulfillment plus the 3.5% fuel and logistics surcharge, inbound freight and placement, monthly storage, storage utilization surcharge, aged inventory surcharge, low-inventory-level fee, returns processing, removal or disposal, and advertising. Amazon's 2026 US update increased average fulfillment fees by about $0.08 per unit; exact rates depend on marketplace, price, category, size, and inventory behavior.
The phrase "Amazon FBA fee" sounds singular. The invoice is not. A product can face a referral fee, fulfillment fee, fuel surcharge, inbound placement, storage, storage utilization, aged inventory, low-inventory, return processing, removal, and advertising cost. Not every fee applies to every unit, but a profit model that includes only referral and fulfillment will overstate margin on many products.
The 2026 headline changes
Amazon's US announcement for 2026 said FBA fees would increase by an average of $0.08 per unit sold. Amazon also announced a 3.5% fuel and logistics-related surcharge on US and Canada FBA fulfillment fees beginning April 17, 2026. European marketplaces received a different fee package, including reductions in some fulfillment and referral categories. This is why a global article, or a global spreadsheet, must not mix US and other-region rates in one table.
The complete FBA fee stack
The selling plan: Professional sellers generally pay a monthly subscription, while individual sellers can pay per item. The referral fee: a percentage of the selling price based on category, sometimes with minimums or price bands. The FBA fulfillment fee: covers picking, packing, and shipping under FBA, varying by size, weight, and price bands. The fuel and logistics-related surcharge: added to applicable fulfillment fees in 2026, calculated on the fulfillment fee rather than the selling price, so the dollar amount varies by product tier.
Inbound freight: the seller pays to move inventory to Amazon. The inbound placement service fee: fewer Amazon destinations can create a per-unit placement fee. Monthly inventory storage: charged for the cubic space units occupy, with different rates by product type and season. The storage utilization surcharge: an additional cubic-volume surcharge for eligible sellers with high weeks of cover. The aged inventory surcharge: charged on inventory stored beyond age thresholds. The low-inventory-level fee: charged on some standard-size products with consistently low historical days of supply. The returns processing fee: charged in categories with return rates above Amazon's threshold. Removal, disposal, and liquidation: exiting FBA inventory isn't free either. And advertising, not technically an FBA fee, but still part of product economics, a 12% ACOS product can be less profitable than a 25% ACOS one if their margins and return rates differ, covered further in ACOS is not profit.
A per-unit example
Consider a US standard-size product sold for $29.99.
| Cost | Example amount |
|---|---|
| Referral fee | $4.50 |
| FBA fulfillment fee and surcharge | $5.20 |
| Inbound freight and placement | $1.10 |
| Product cost | $8.75 |
| Advertising | $3.00 |
| Return allowance | $0.80 |
| Storage and inventory-fee allowance | $0.45 |
| Estimated contribution | $6.19 |
The exact numbers are illustrative. The important point is that referral and fulfillment fees are only part of the cost, a model covered in full detail in how to calculate Amazon profit per SKU.
How much does Amazon take from each sale?
The honest answer: it depends on what you count. If the question is only about referral and fulfillment deductions, the percentage can be estimated from the rate card. If the question is how much of revenue disappears before profit, the model must include advertising, returns, inbound, storage, and product cost. A one-line "Amazon takes 30%" answer is too broad for a business decision.
Fees that need an allowance rather than a direct unit charge
Some costs aren't posted neatly against the same sold unit. Allocate storage by unit volume and days held, aged fees to affected inventory, returns using expected cost per sold unit, and placement by shipment units or weighted volume. The model should expose assumptions, since hidden allocations create false precision.
A monthly 2026 fee audit
Preview current fees using Amazon's Fee Preview or Revenue Calculator tools and confirm size and weight data. Reconcile actual charges using settlement transactions and fee reports. Rank changes by contribution impact, since an eight-cent increase on a million units matters more than a one-dollar increase on 200 units. Review inventory-behavior fees: aged inventory, low-inventory, storage utilization, and returns processing exposure. Update prices and ad limits selectively rather than raising every price by the same amount.
The eight cents that wasn't the real problem
A seller updated a spreadsheet when Amazon announced the average eight-cent FBA increase, adding $0.08 to every product cost and considering the work finished. In April, the fuel surcharge added more cost. One large standard product also moved into a different fee band after a packaging change, while a slow product began incurring aged and utilization charges. The eight-cent average was accurate as a headline and useless as a SKU model. Switching to a monthly fee audit and updating size, weight, fee preview, placement, storage, returns, and ad cost for the top 50 products first revealed the largest margin leak actually came from packaging dimensions, not the announced average increase. The same 2026 fuel and logistics surcharge later extended to non-Amazon channel orders too, see Amazon Multi-Channel Fulfillment in 2026 for how that changes the cost of shipping Shopify or other external orders from FBA inventory.

Frequently asked questions
What percentage does Amazon FBA take in 2026?
There's no single percentage. Referral fees depend on category, fulfillment depends on size and weight, and inventory-behavior fees depend on storage, age, returns, and supply level. A one-line answer is too broad for a real business decision.
Did Amazon raise FBA fees in 2026?
Amazon announced an average US FBA fulfillment fee increase of about $0.08 per unit for 2026 and later added a 3.5% fuel and logistics-related surcharge on US and Canada fulfillment fees starting April 17, 2026. Other marketplaces received different changes.
Are FBA storage fees included in the fulfillment fee?
No. Monthly storage and related surcharges (aged inventory, storage utilization) are separate charges from the per-unit fulfillment fee, and they show up as distinct line items on statements.
