As of November 8, 2026, Amazon has published the fee card that will govern its United States marketplace for most of next year, and the headline number is small enough to be missed. Fulfillment fees rise by an average of 19 cents per unit, about 0.8 percent of an average item's selling price, with most changes taking effect on 15 January 2027Amazon Seller Central: 2027 updates to US referral and fulfillment fees. The parts that actually move margin sit elsewhere: a new charge on Buy X Get Y promotions, a single age based storage rate, and a low inventory rule measured on 28 days of supply seen both before and after the check.
What Changes on 15 January
Amazon frames the changes as cost alignment: fees for some products rise, others fall, so each fee tracks the cost of fulfilling that product more closely. That framing is fair and also beside the point for a seller, because a catalog is not an average. Averages are where fee changes hide, and the only number that matters is the change multiplied by your own units.
| Item | Effective | What changes | Who feels it first |
|---|---|---|---|
| Fulfillment fee | 15 January 2027 | Average plus 19 cents per unit | Every FBA seller, unevenly by size and price |
| Low price FBA rate | 15 January 2027 | Narrowed categories; automotive, compact appliances, computers, instruments and media lose eligibility | Sellers pricing under 10 dollars in those categories |
| Size tiers | 15 January 2027 | Bulky items move to four tiers, extra large to six oversize tiers | Sellers of large and heavy units |
| Promotion fee | 15 January 2027 | 5 dollars up-front plus 2 percent variable on Buy X Get Y, capped at 2,000 dollars | Brands running bundle promotions |
| Promotion billing | February 2027 | All promotions billed monthly | Finance teams closing January |
| Storage | 1 February 2027 | Utilization surcharge removed, aged surcharge merged into one age based rate | Sellers holding slow movers |
| Low inventory fee | 1 February 2027 | Applies only under 28 days of supply, tested before and after | Sellers with spiky or seasonal demand |
The 19 Cents Average Hides the Spread
The published detail is more useful than the average. Standard size items priced between 10 and 50 dollars rise by about 40 cents for small standard and 12 cents for large standard, while the low price FBA rates stop applying to automotive, compact appliances, musical instruments, media and computersAmazonFBA: FBA fees for 2026 and 2027. Bulky and extra large items are redivided into four and six tiers, which means the direction of the change depends entirely on the box you ship.
For a catalog with a mix of sizes, the average is close to meaningless in both directions. A seller with mostly small standard units above 10 dollars will feel a larger increase than 19 cents. A seller with heavy bulky units in the new lighter tiers may see fees fall. The only way to know is to rank ASINs by monthly units multiplied by the per unit change and look at the top ten, which usually carry most of the dollar impact.
The Bands Around 10 and 50 Dollars
Two price points deserve a second look before January: just above 10 dollars and just above 50 dollars. Both sit on tier boundaries where the applicable rate changes, and both are places where a one dollar price move can be cheaper than staying put. Sellers who reprice around these lines in December do it with the 2026 card in hand, which is exactly the wrong card.
Storage Moves to an Age Based Rate
From 1 February, the storage utilization surcharge disappears and the aged inventory surcharge is folded into monthly storage as a single rate that varies by age. Inventory turning in under six months gets flat or lower fees, aged inventory gets higher ones, and the rate becomes easier to predict. The intended behaviour change is obvious: stock up before a peak without a utilization penalty, and clear slow movers before they age.
AWD follows a similar logic with new numbers: 1.55 dollars processing per box, 1.58 dollars transportation per cubic foot, and a 40 percent inbound processing discount for single SKU pallets, with storage for inventory older than 12 months charged at 2.5 times the standard rate from March. Sellers who consolidated inbound shipments to save on placement fees now have to weigh that against the age penalty on whatever they cannot sell through.
The 28 Day Rule Rewrites Replenishment
The low inventory level fee is the change most likely to be misread. Today it is assessed on trailing 30 and 90 day sales. From 1 February it applies only when inventory falls below 28 days of supply, based on actual shipments in the four weeks before and the four weeks after the assessment dateSeller Adventures: what the 0.19 average hides. The second window is the important one, because it confirms whether low inventory reflected ongoing demand or a one-off spike.
| Measure | Before 1 February | From 1 February | Effect on replenishment |
|---|---|---|---|
| Sales window used | Trailing 30 and 90 days | Four weeks before and four weeks after | Spikes no longer trigger the fee alone |
| Trigger level | Relative to historical demand | Under 28 days of supply | Supply days becomes the planning unit |
| Seasonal and end of life stock | Could be charged | Largely excluded by the second window | Clearance treated differently |
| New professional sellers | Exempt for 365 days | Unchanged | New accounts keep the runway |
Why the Second Four Weeks Matter
Because it separates a stocking failure from a demand surprise. A SKU that ran dry because a creator mentioned it has demand in the forward window and will not be penalised the same way as a SKU that ran dry because nobody reordered. Practically, this rewards sellers who keep a replenishment calendar and punishes those who react only after the fee appears on an invoice.
Recosting Promotions Before Q1
Buy X Get Y promotions, both bundle and percent off, gain a 5 dollar up-front fee plus a 2 percent variable fee capped at 2,000 dollars, mirroring the structure Amazon already applies to coupons and deals. From February all promotions are billed monthly, so anything that would have been charged in January rolls into the first February cycle. The up-front fee hits small sellers hardest, because it is fixed regardless of how many units the promotion moves.
The arithmetic that matters is per promotion, not per brand: units lifted times contribution margin, minus the up-front fee, minus 2 percent of promotional sales. For a low volume bundle, that subtraction can turn a promotion that looked profitable on a spreadsheet into a loss. Recosting every bundle in the first quarter plan is a two hour exercise that is much cheaper than discovering it in March.
