Amazon Q4 2026 peak fees run October 15, 2026 to January 14, 2027. Fulfillment costs about $0.32 more per unit than off-peak, the 3.5% fuel and logistics surcharge (new since April 2026) stacks on top, and monthly storage for standard-size items roughly triples, from about $0.78 to $2.40 per cubic foot for October through December.
The per-unit peak rate itself is flat versus last year. What quietly bites is the surcharge: a Q4 deal that pencils out on 2025 fee math can run margin-negative once you add it in. Rerun the numbers first.

What are Amazon’s Q4 2026 peak fees?
Amazon’s Q4 2026 peak fees run October 15, 2026 through January 14, 2027: fulfillment rises by about $0.32 per unit on average, and the 3.5% fuel and logistics surcharge stacks on top. Monthly standard-size storage steps from about $0.78 to $2.40 per cubic foot for October through December.
Peak fees are Amazon’s holiday surcharge on FBA. For the 2026 season they apply from October 15, 2026 through January 14, 2027 across FBA, Remote Fulfillment, Multi-Channel Fulfillment, and Buy with Prime. Two costs move: per-unit fulfillment fees and monthly storage.
The per-unit fulfillment increase averages $0.32 per unit, the same step-up Amazon charged in 2025. Storage is the bigger swing. From October through December, standard-size monthly storage rises from about $0.78 to $2.40 per cubic foot, and oversize from about $0.56 to $1.40, billed on the 15th of each month on your average daily volume.
Monthly FBA storage fee per cubic foot: off-peak vs Q4 peak (2026)
Standard-size storage roughly triples for October through December; oversize roughly 2.5x.
Storage is billed on the 15th of each month on average daily inventory volume, so units that sit through October, November, and December pay the peak rate three times. Sources linked below.
When do the 2026 peak fees start and end?
The fee window opens October 15, but the dates that decide your bill are the inbound deadlines before it. Miss them and your holiday inventory either arrives late or sits in storage longer at the peak rate. Here is the calendar that matters for Q4 2026.

The six dates that set your peak-season cost, in order.
FBA inbound should arrive by October 21 for minimal shipment splits or October 28 for Amazon-optimized splits; AWD inventory by October 14. Deadlines are earlier than 2025, so build in buffer.

This is the part most fee explainers skip. Restating the fee table is easy; doing the margin math is the work. Take a single standard-size unit with a roughly $5.00 base fulfillment fee and a footprint of about 0.10 cubic feet, and compare what it costs to move off-peak versus during the Q4 peak.
| Cost line, per unit | Off-peak | Q4 peak | Change |
|---|---|---|---|
| Fulfillment fee | $5.00 | $5.32 | +$0.32 |
| Fuel + logistics (3.5%) | $0.18 | $0.19 | +$0.01 |
| Storage (0.10 cu ft, 1 mo) | $0.08 | $0.24 | +$0.16 |
| Per-unit total | $5.26 | $5.75 | +$0.49 |
That is about $0.49 more per unit, and it compounds. For a brand moving 6,000 units in Q4, the fulfillment and surcharge step alone is roughly $2,000, before you count storage on every unit that sits unsold through the peak months. On a thin-margin SKU, half a dollar is the difference between a profitable promo and one that loses money on volume.

Illustrative: fulfillment fees vary by size and weight. Storage recurs for each month a unit is held, so slow movers pay it two or three times. Getting fee-aware pricing right is the same discipline behind lowering your TACoS without losing sales.
How do you protect your margin during Q4 2026?
The fees are fixed, but your exposure is not. Four levers do most of the work: use AWD to defer the storage jump, hit the inbound deadlines, reprice on 2026 math, and clear slow inventory before it ages into surcharges. The single biggest one is AWD. And if new ad commitments are also on your Q4 list, see what the Amazon Ads ChatGPT pilot actually opens to sellers before you budget for it.
Put simply: match the fulfillment path to how fast each SKU sells. Fast movers can sit in FBA; deep holiday buffers belong in AWD, where the storage rate stays off-peak two weeks longer and the surcharge waivers kick in. This is the same forecasting discipline covered in our Amazon inventory forecasting guide.
| Q4 storage path | FBA direct | AWD + auto-replenishment |
|---|---|---|
| Peak storage starts | October 15 | November 1 (off-peak held through Oct 31) |
| Low-inventory-level fee | Applies | Waived above 70% auto-replen |
| Aged-inventory surcharge (181 to 365 days) | Applies | Waived above 70% auto-replen |
| Best for | Fast-selling hero SKUs | Deep holiday buffer stock |
None of this is complicated, but it is a lot to run per SKU during your busiest quarter. If you would rather hand it off, that is exactly what a full-service Amazon agency does, and it usually costs less than founders expect: see how much an Amazon agency costs in 2026.
ROAS 0.5 to 2.0, TACoS 100%+ to about 10%
When a sustainable bar soap brand came to Amplifyr burning money on ads, we rebuilt the fee and bid math and took the launch from red to profitable, ROAS 0.5 to 2.0 and TACoS from over 100% to roughly 10%. Peak-season cost control is the same muscle: know the real per-unit number, then price and stock to it.
