by spencer kCheck your Seller Central storage calendar and you’ll see it: the rate card flips over on October 1, and whatever you’re still holding in FBA gets a lot more expensive to store through the end of the year. If you’ve got slow-moving stock sitting in a fulfillment center right now, understanding Amazon’s Q4 storage fees for 2026 before that date hits is the difference between a manageable cost and a bill that eats your margin on units that weren’t even selling.
What’s changing with Amazon’s Q4 storage fees
Amazon runs two storage fee periods each year: a lower rate for January through September, and a steeper one for October through December that covers the peak shopping season. Based on the rate schedule Amazon has published for this year, standard-size inventory moves from roughly $0.78 per cubic foot in the off-peak months to around $2.40 per cubic foot once Q4 starts — call it a three-times jump. Oversize inventory sees a similar pattern, stepping up from about $0.56 to roughly $1.40 per cubic foot. Those numbers move by category and can shift between rate card updates, so treat them as a planning estimate and check your own account’s current fee schedule before you do the math on a specific SKU.
This isn’t a penalty or a surcharge triggered by anything you did — every seller pays the Q4 rate on whatever’s sitting in an Amazon warehouse during those three months, whether it’s fast-moving holiday stock or inventory that’s been stalled since spring. The fee applies per cubic foot per month, so a unit that sits through all of October, November, and December gets charged three times over. Amazon’s reasoning is straightforward: warehouse space is at its tightest right before the holidays, when every seller is trying to get stock in for Black Friday and Cyber Monday, so the fee schedule is built to make sellers think twice before parking slow inventory in that space instead of using it to turn over fast-moving stock.
How this is different from the aged inventory surcharge
It’s easy to conflate the Q4 storage rate with Amazon’s aged inventory surcharge, but they’re separate charges that can both land on the same unit. The Q4 rate is a seasonal bump on your regular monthly storage fee — it applies to everything, new arrivals included, purely because of the calendar. The aged inventory surcharge is triggered by how long a specific unit has been sitting in storage, regardless of season, and kicks in well before Q4 even starts under the current fee schedule. If you’re holding stock that’s both been sitting for months and about to roll into the Q4 window, you’re looking at two separate line items stacking on the same units — which is exactly the inventory worth reviewing first. Pull your inventory age report and cross-reference it against what’s about to roll into Q4; anything that shows up on both lists is costing you twice and should move to the top of your list to deal with.
The real cost of carrying excess inventory into October
Run the math on what you’re actually holding. Take a pallet of slow-moving product that would cost, say, $40 a month to store at the off-peak rate — under the Q4 rate card, that same pallet runs closer to $120 a month, and if it sits through all three peak months you’re looking at roughly $360 versus the $120 it would have cost at the January-through-September rate. Multiply that across every SKU you know isn’t moving and the number stops being an abstraction. The units generating that bill aren’t earning anything back while they sit there; they’re just accumulating storage charges against inventory you already paid to acquire.
The sellers who get hurt worst by Amazon’s Q4 storage fees are the ones who wait until November or December to act, once the higher rate has already applied for a month or two and the fee is showing up as a surprise on the statement. Reviewing your inventory age report now, while you’ve still got time before October 1, is the cheapest version of this problem to solve.
What to do before the Q4 rate kicks in
None of these require picking one path — most sellers end up combining two or three depending on how much dead stock they’re actually carrying.
- Sort your inventory by age and sell-through, not just total units. A SKU with a healthy sell-through rate can absorb the Q4 rate for a month or two without much damage. A SKU that hasn’t moved in ninety days is where the fee actually costs you something.
- Discount or bundle what’s genuinely dead before the rate flips. Selling through even part of a slow-moving lot at a markdown in September beats paying peak-season storage on it through December.
- File a removal order for stock you have no realistic path to sell. Pulling inventory out of FBA has its own cost — see our breakdown of FBA removal order fees — but for units with no sell-through in sight, removal usually beats three more months of Q4 storage charges.
- Sell the excess in bulk instead of storing it through peak season. If you’d rather convert dead stock into cash now than keep feeding it into a fee schedule that’s about to triple, that’s the option Recouply exists for — we buy excess and slow-moving inventory outright, so it stops costing you storage the same week you ship it out.

FAQ: Amazon’s peak season storage costs
When do Amazon’s Q4 storage fees start?
The peak storage rate typically applies to inventory held from October 1 through December 31, billed monthly based on what’s in the warehouse during that window. Always confirm the exact dates and rates in your own Seller Central account, since Amazon can adjust the schedule from year to year, and different size tiers sometimes see the change apply on slightly different terms.
Is the Q4 rate the same as the aged inventory surcharge?
No. The Q4 rate is a seasonal increase on standard monthly storage that applies to all inventory during peak months, regardless of how long it’s been there. The aged inventory surcharge is a separate charge based on how long a unit has sat in storage, and it can apply at any time of year, not just Q4 — so a unit can rack up both at once.
Can I avoid Q4 storage fees by removing inventory in September?
Yes — inventory that’s out of FBA before October 1 doesn’t get charged the peak-season rate on those units, though you’ll still pay whatever removal or disposal fee applies to get it out. For stock with little realistic chance of selling through, moving it out ahead of the rate change is usually the cheaper path over the next three months.
