As of 8 November 2026, Amazon's 2027 fee update is four days old and most sellers are still reading it as a single event. It is two. Fulfilment fees move on 15 January, while the storage structure and the low-inventory-level fee move on 1 February. For a brand that sets SKU prices off landed cost, that six-week gap is where margin quietly leaks, because the repricing decision and the inventory decision no longer share a deadline.
What Amazon actually changed
The announcement itself is short. Independent sellers account for more than 60% of sales in Amazon's store, and for those using Fulfilled by Amazon the average increase works out at roughly 0.8% of the average item's selling price. Amazon says some products will cost more and others less, so that each fee tracks its real fulfilment cost more closely. The 2026 increase was $0.08 per unit, which makes this year's step roughly double.
What is missing from the announcement matters as much as what is in it. The rate tables sit behind a Seller Central login, referral fees are not mentioned, and the new age-based storage bands are not published with prices. A brand cannot build a 2027 price ladder from the press release alone; it has to pull product-level numbers from the Fee Change Comparison dashboard in Profit Analytics.
Two clocks, two decisions
The January clock is a pricing question
A $0.19 average hides a wide spread. On a $9 item the increase can eat more than two points of contribution margin, while on a $90 item it is noise. That is why repricing has to happen at SKU level rather than at category level: a brand that raises every price by the same percentage will overprice its expensive lines and under-recover on its cheap ones. The practical move before 15 January is to sort the catalogue by fee change as a share of selling price, then decide which SKUs absorb the cost and which pass it through.
The February clock is an inventory question
The storage change turns the question from how much space a SKU occupies to how long each unit sits. Amazon says inventory that turns within six months will cost the same or less, and aged inventory will cost more. The low-inventory change points the other way: a SKU that drops below 28 days of supply still gets charged, and the assessment now looks at actual shipments in the four weeks before and after, which should filter out one-off demand spikes but also makes a lumpy replenishment pattern more visible.
Read together, the two changes squeeze from both ends. Keep too much and the age-based rate punishes you; keep too little and the low-inventory fee does. The only way to sit between them is to hold a buffer outside Amazon and replenish on a cadence, which is an operating change, not a pricing one.
Where the price ladder breaks
Most catalogues contain three kinds of SKU, and the 2027 rules treat them differently. Sorting the catalogue this way before repricing is faster than working product by product, because the fee exposure clusters by turnover rather than by category. The split also explains why a single average fee number is a poor planning input: the same increase lands on three different cost structures.
| SKU archetype | Old assumption | New cost driver | Price action before January |
|---|---|---|---|
| Fast mover, turns under 30 days | Storage is a rounding error | Low-inventory fee if supply dips below 28 days | Hold price, protect replenishment cadence |
| Steady mid-rotator, 60 to 120 days | Ignore until the annual review | $0.19 per unit plus a flat or lower age rate | Absorb on hero SKUs, adjust the tail |
| Slow or seasonal, over six months | Sunk cost, park it in FBA | Age-based storage rate rising with time | Cut price to clear, or move stock out |
The third row is where most of the money is. A discount taken in December to clear slow stock is usually cheaper than an age-based storage charge accumulated through the spring, and it has a second effect: clearing the tail removes the SKUs that distort the price gap between a brand's hero product and its long tail, which is exactly the comparison shoppers make on a product listing.
What to do before 15 January
The sequence matters more than the checklist. Reprice first, then fix replenishment, then negotiate. A brand that starts by asking for cost relief has nothing to trade with; a brand that arrives with a SKU-level cost model and a clearing plan is having a different conversation.
None of this changes what shoppers see on a product listing. It changes what the brand can afford to keep visible there, which in a category where price gaps of a few percent decide the buy box is the same thing seen from a different angle.
FAQ
Is the $0.19 increase the whole story?
No. It is the average fulfilment change from 15 January. The storage and low-inventory changes land on 1 February and can move cost far more for slow-moving or lumpy SKUs.
Should every SKU be repriced by the same percentage?
No. Convert the fee change to a share of selling price first. A flat percentage overprices expensive items and under-recovers on cheap ones.
Does sending stock earlier avoid the February storage change?
Not by itself. Stock sent in January still ages into the new rate. What matters is how long each unit sits, not when it arrived.
What is the cheapest way to handle slow stock?
Usually a planned discount before the age-based rate compounds, combined with moving the remainder out of FBA rather than parking it there.
