Amazon’s Q4 2026 fee structure isn’t just “higher fees” during the holidays – it’s two separate windows with different start and end dates, plus several surcharges that can stack on the same unit at the same time. If you’re buying wholesale inventory to carry into Q4, knowing exactly when each window opens matters more than the headline peak rate.
Two Windows, Two Different Timelines
Peak storage runs October 1 through December 31, 2026, then drops back to off-peak rates on January 1. Peak fulfillment fees run on a different schedule: October 15, 2026 through January 14, 2027. That leaves a gap at both ends – October 1 through 14 falls under peak storage but not peak fulfillment, and January 1 through 14 is the reverse, peak fulfillment without peak storage. The 3.5% fuel and logistics surcharge that’s been in effect since April 17, 2026 applies on top of whichever fulfillment rate is active, with no announced end date.
Why the October 1 Snapshot Matters More Than October 15
Storage costs are set by your inventory level on the October 1 snapshot, not whenever peak fulfillment technically begins. In practice, that makes early October – not mid-October – the real deadline for clearing out stock you don’t want to carry at peak storage rates. A unit that sells on January 5 pays the peak fulfillment fee but is still stored at the standard, off-peak rate, since peak storage already ended on December 31.
What Can Stack on a Single Unit in Q4
| Fee | When It Applies | Approx. Rate (varies by source – verify in Seller Central) |
|---|---|---|
| Peak base storage | All Q4 inventory, October 1 – December 31 | Standard-size ~$2.25–$2.40/cu ft (up from ~$0.78–$0.87 off-peak); oversize ~$1.30–$1.40/cu ft (up from ~$0.56) |
| Aged inventory surcharge | Stock held 181+ days | ~$1.25/cu ft at 181–270 days, rising steeply at older tiers (e.g. ~$6.90/cu ft at 366–455 days) |
| Storage utilization surcharge | Inventory exceeds roughly 22 weeks of trailing 13-week shipped volume | ~$0.23–$0.44/cu ft off-peak; Q4 inbound shipments often trigger it as stock rises ahead of sales |
| Low-inventory-level fee | Days of supply falls below Amazon’s threshold, now tracked at the FNSKU level | Applies per individual variation, not just per parent listing |
A Quick Worked Example
One published trade-press model estimates that for 3,000 units of a 0.20 cubic-foot SKU, monthly storage rises from roughly $492 (January–September rates) to roughly $1,398 (October–December peak rates) – a difference of about $2,718 over the quarter on that SKU alone, before any aged-inventory or utilization surcharges are added. These are third-party estimates rather than Amazon’s own published figures, so treat them as a planning reference and confirm your actual rates in Seller Central.
What This Means for How Much You Buy
None of this means you should under-stock for Q4 – a stockout during the holiday rush costs more than a few months of peak storage. But it does argue against over-ordering out of fear of running out, since excess inventory sitting past December 31 can stack peak storage, aged-inventory, and utilization surcharges all at once. Clearing slow-moving stock before the October 1 snapshot, shipping in smaller staggered batches rather than one large inbound, and having a wholesale supplier you can reorder from quickly all reduce how much safety stock you need to carry into the window in the first place.

Frequently Asked Questions
What are Amazon’s two separate Q4 2026 fee windows?
Peak storage runs October 1 through December 31, 2026. Peak fulfillment fees run October 15, 2026 through January 14, 2027 – a different schedule that opens two weeks later and closes two weeks later.
Why does the October 1 snapshot matter more than October 15?
Storage costs are set by your inventory level on the October 1 snapshot, so the practical deadline for clearing unwanted stock is early October, even though peak fulfillment fees don’t technically start until October 15.
What is the storage utilization surcharge and when does it apply?
It applies when your inventory volume exceeds roughly 22 weeks of your trailing 13-week shipped volume. Q4 inbound shipments often trigger it, since stock levels rise ahead of actual sales during the ramp-up to the holidays.
Can multiple Q4 surcharges apply to the same unit?
Yes. Peak base storage, the aged-inventory surcharge, the storage utilization surcharge, and the ongoing 3.5% fuel and logistics surcharge can all apply to the same slow-moving unit at the same time.
How much more expensive does peak storage get?
Published estimates put standard-size storage rising from roughly $0.78–$0.87 off-peak to roughly $2.25–$2.40 per cubic foot at peak, and oversize rising from roughly $0.56 to roughly $1.30–$1.40 per cubic foot. These figures vary by source, so confirm your current rates in Seller Central.
Does the fuel and logistics surcharge apply on top of peak fulfillment fees?
Yes. The 3.5% fuel and logistics surcharge has been in effect since April 17, 2026 with no announced end date, and it applies on top of whichever fulfillment fee rate – standard or peak – is currently active.
What’s the aged-inventory surcharge rate during this window?
Stock held 181 to 270 days faces roughly $1.25 per cubic foot, and the rate climbs steeply at older age tiers – for example, roughly $6.90 per cubic foot for inventory held 366 to 455 days.
How should wholesale resellers adjust Q4 buying based on this?
Avoid over-ordering purely to dodge a stockout – excess inventory sitting past year-end can stack several Q4 surcharges at once. Clear aged stock before the October 1 snapshot, consider smaller staggered inbound shipments instead of one large one, and prioritize having a wholesale supplier you can reorder from quickly over carrying extra safety stock.
