Amazon Q4 Storage Fees 2026: Planning Guide for Wholesale Sellers
-1200x627.png&w=3840&q=75)
Here's a piece of math every wholesale seller should run before placing September purchase orders. Take a product in a 12 by 10 by 8 inch box, about 0.56 cubic feet. Store 500 units of it in FBA, and from January through September the monthly storage bill runs around $217. Store the same 500 units in November, and the bill is roughly $667 a month. Nothing about the inventory changed. The calendar did.
From October through December, Amazon's monthly storage rates roughly triple, and for wholesale sellers, who buy in bulk by definition, that jump quietly rewrites the economics of every Q4 order.
Order too little and you stock out in the highest-demand weeks of the year. Order too much, and you pay peak rates to warehouse your mistake, with more surcharges waiting behind it. This guide covers the 2026 rates, the fees that stack on top of them, and how to size and time Q4 orders so storage costs stay a line item instead of a margin killer.
The 2026 Q4 Storage Rates
Amazon charges monthly storage on the average daily volume your inventory occupies, measured in cubic feet. For 2026, the published rates are:
Standard-size products: $0.78 per cubic foot from January through September, rising to $2.40 per cubic foot from October through December.
Oversize products: $0.56 per cubic foot from January through September, rising to $1.40 per cubic foot from October through December.
That's roughly a 3x increase for standard-size inventory in the exact months you hold the most of it. The fee is billed monthly in arrears, so October's storage appears on your statement in November, which is worth knowing so the first peak-season bill doesn't read like an error. And because Amazon adjusts its fee schedule periodically, confirm the current numbers in Seller Central's fee pages before you finalize your Q4 budget; the planning logic below holds regardless of the exact rate.
A note on what counts as standard-size, since it decides which rate you pay: standard-size generally means at or under 20 pounds and within 18 by 14 by 8 inches. Anything beyond that falls into the larger tiers, with lower per-cubic-foot rates but more total cubic feet.
Frequently asked questions
How much are Amazon storage fees in Q4 2026?
Per Amazon's published 2026 rates, standard-size inventory costs $2.40 per cubic foot per month from October through December, up from $0.78 the rest of the year. Oversize inventory rises from $0.56 to $1.40 per cubic foot. Confirm current figures in Seller Central, as Amazon adjusts its fee schedule periodically.
Why are Amazon storage fees higher in Q4?
Fulfillment center space is scarcest from October through December, when nearly every seller is inbounding holiday inventory at once. The roughly 3x peak rate is Amazon pricing that scarcity, and it's designed to discourage sellers from parking excess stock in FBA during the quarter.
How do I avoid high Q4 storage fees?
You can't avoid the peak rate on inventory you genuinely need, but you can minimize what it applies to: inbound roughly 8 to 10 weeks of expected peak sales rather than the whole season at once; hold reserve stock outside FBA and replenish in stages, trim packaging cubic footage, and clear slow movers before October so they don't sit through the expensive months.
