Amazon FBA storage looks affordable at first glance: the base rate for standard-size products is under a dollar per cubic foot per month. But that number only applies nine months of the year, and only while your inventory sells quickly. Peak-season rates, utilization surcharges and aged-inventory fees can multiply what you actually pay. This guide breaks down the current 2026 FBA storage and aged-inventory fees, walks through a 12-month cost example, and explains why many sellers keep only fast-moving stock in FBA and store the rest with a 3PL.
Amazon FBA Storage Fees in 2026
Amazon charges storage by the cubic foot your inventory occupies in its fulfillment centers. Several fees stack on top of each other, so it helps to look at them one at a time. All figures below are for U.S. marketplace, non-dangerous-goods inventory.
Monthly Storage Fees
| Size tier | January–September | October–December |
| Standard-size | $0.78 per cu ft | $2.40 per cu ft |
| Oversize | $0.56 per cu ft | $1.40 per cu ft |
The jump in Q4 is the biggest surprise for many sellers: standard-size storage costs about three times as much from October to December — exactly when most brands are holding the most inventory.
Storage Utilization Surcharge
Professional sellers who store more than about 22 weeks of supply pay an extra surcharge on top of the base rate. For standard-size products it ranges from $0.44 to $1.88 per cubic foot, so the all-in monthly rate can reach $2.66 off-peak and $4.28 in Q4. New sellers and accounts storing under 25 cubic feet a day are exempt.
Aged Inventory Surcharge
Once a unit has been in a fulfillment center for more than 180 days, Amazon adds a monthly aged-inventory surcharge on top of regular storage. The rates climb steeply after nine months, and in 2026 Amazon added a new, higher tier for inventory older than 455 days.
| Days in inventory | Surcharge per cu ft / month | Per-unit minimum |
| 181–210 | $0.50 | — |
| 211–240 | $1.00 | — |
| 241–270 | $1.50 | — |
| 271–300 | $5.45 | — |
| 301–330 | $5.70 | — |
| 331–365 | $5.90 | — |
| 366–455 | $6.90 | $0.30 per unit |
| 456+ | $7.90 | $0.35 per unit |
For the oldest tiers, Amazon charges whichever is higher — the per-cubic-foot rate or the per-unit minimum. Clothing, shoes, bags, jewelry and watches skip the 181–270 day tiers and start paying at 271 days.
Other Fees That Shape Your Storage Strategy
• Low-inventory-level fee: if you keep less than about four weeks of supply in FBA, Amazon charges a per-unit fee on top of fulfillment — so you can’t simply move everything out.
• Removal and disposal fees: pulling slow stock out of FBA costs from $0.84 per unit for the smallest standard-size items, rising with weight.
• Holiday peak fulfillment fee: from mid-October to mid-January, per-unit fulfillment fees are also higher, adding to Q4 costs.
Cost Example: FBA vs 3PL Storage Over 12 Months
Take a seller storing 2,000 standard-size units at 0.2 cubic feet each — 400 cubic feet on average throughout the year. One slower product line takes up 100 cubic feet and sits for a full year before it sells through.
We assume the account stays under 22 weeks of supply, so no utilization surcharge applies.
| Cost item | Amazon FBA | ASTORAGE 3PL ($0.65/cu ft) |
| Storage, Jan–Sep (9 months) | $2,808 | $2,340 |
| Storage, Oct–Dec (3 months) | $2,880 | $780 |
| Aged surcharge on 100 cu ft (months 7–12) | $2,005 | $0 |
| 12-month total | $7,693 | $3,120 |
Off-peak, the two options are close: $312 a month at Amazon versus $260 at the 3PL. The gap opens in Q4, when FBA storage for the same 400 cubic feet jumps to $960 a month, and again as the slow product line ages past six months. By the end of the year, the slow line alone has added $2,005 in surcharges — more than half of what the 3PL charged to store everything.
This example covers storage only. Keeping reserve stock at a 3PL means paying to ship replenishments into Amazon, so factor in that freight and any prep work. Use our guide on how to calculate cubic feet to run the numbers for your own products.
Why a 3PL Gives You More Flexibility Than FBA Storage
Amazon’s base rate can look like the cheaper option. The real difference is in how the two models treat seasonality, slow inventory and sales outside Amazon.
One Rate All Year — No Peak-Season Increase
FBA storage roughly triples in Q4, right when you need the most space for holiday stock. With ASTORAGE cubic storage, you pay the same price year-round, prorated daily, so building up inventory for the holidays doesn’t come with a seasonal penalty.
No Forced Removal of Slow Sellers
In FBA, slow sellers get squeezed out. Aged surcharges climb every month after 180 days, a low Inventory Performance Index can cut your storage capacity, and the usual way out — removal or disposal — costs money per unit and loses the stock. A 3PL charges the same rate whether a product sells in one month or twelve, with no long-term storage fees, so you can hold seasonal items, slow movers and bulk reserve stock until the timing is right.
One Stock Pool for Every Sales Channel
Inventory in FBA is effectively locked to Amazon. Stock held at a 3PL can ship to any channel: replenishment for FBA, Amazon FBM orders, Shopify and WooCommerce, Walmart, TikTok Shop or B2B. One shared pool means less total inventory, fewer stockouts on one channel while another is overstocked, and a single place to manage it all.
How to Combine FBA and 3PL Storage
The lowest-cost setup for most sellers is a hybrid, not an either-or choice:
1. Keep fast movers in FBA — around four to eight weeks of supply, enough to avoid the low-inventory-level fee and stay under the utilization surcharge threshold.
2. Store reserve and slow-moving stock at a 3PL — bulk inventory, seasonal products and anything at risk of passing 180 days.
3. Replenish FBA on a schedule — small, regular shipments based on sales velocity, with Amazon FBA prep done before stock leaves the warehouse.
4. Review aged inventory monthly — pull anything approaching the 271-day tier back to the 3PL or into another channel before the surcharge jumps.
Amazon Warehousing & Distribution (AWD) is another option for bulk stock that will only ever sell on Amazon. It automates replenishment into FBA, but like FBA it keeps inventory tied to Amazon, so it doesn’t help if you also sell on other channels.
Location Matters for Replenishment
The closer your 3PL is to Amazon’s fulfillment centers, the faster and cheaper each replenishment shipment becomes. Warehouses near major Amazon hubs shorten replenishment cycles and lower inbound freight, and strategic placement can cut transfer costs by up to 30%. For international sellers, a U.S. warehouse near the ports also makes it easier to consolidate imports before sending them to Amazon.
The Bottom Line
FBA storage is competitive for products that sell quickly outside Q4. For everything else — holiday build-up, slow sellers and inventory you sell across several channels — the fees add up fast. Pairing a lean FBA inventory with flexible 3PL storage keeps Prime eligibility while removing peak-season increases and aged-inventory penalties from your costs.
Frequently Asked Questions
How much does Amazon charge for FBA storage in 2026?
For standard-size, non-dangerous-goods products, Amazon charges $0.78 per cubic foot per month from January to September and $2.40 from October to December. Oversize items cost $0.56 and $1.40. Sellers with more than about 22 weeks of supply can pay a utilization surcharge on top, bringing standard-size storage up to $4.28 per cubic foot in Q4.
When does the aged inventory surcharge start?
It applies once inventory has been in a fulfillment center for more than 180 days. It starts at $0.50 per cubic foot per month, jumps to $5.45 at 271 days and reaches $7.90 for inventory older than 455 days. Clothing, shoes, bags, jewelry and watches start paying at 271 days.
Why are FBA storage fees higher in Q4?
Space in Amazon’s fulfillment centers is in highest demand during the holiday season, so Amazon raises storage rates from October to December. For standard-size products the rate roughly triples, which hits hardest when brands are building up holiday stock.
Is 3PL storage cheaper than Amazon FBA storage?
Off-peak, the base rates are fairly close. The savings come from what a 3PL doesn’t charge: no Q4 increase, no aged-inventory surcharge and no utilization surcharge. In our 12-month example above, storing 400 cubic feet cost $7,693 in FBA versus $3,120 with ASTORAGE. Remember to factor in freight for shipping replenishments to Amazon.
Will my products keep Prime eligibility if I store them at a 3PL?
Yes, as long as you keep enough stock in FBA to cover sales. In a hybrid setup, the units customers order still ship from Amazon’s fulfillment centers with Prime, while the 3PL holds reserve inventory and replenishes FBA as it sells down.
How much inventory should I keep in FBA?
Most sellers aim for roughly four to eight weeks of supply. Below about four weeks, Amazon can charge a low-inventory-level fee and you risk stockouts; above about 22 weeks across your account, the utilization surcharge kicks in. Keeping the rest at a 3PL lets you stay inside that range.
What happens to slow-moving inventory at a 3PL?
Nothing changes: it’s billed at the same rate as any other inventory, however long it stays. There are no long-term storage fees, so you can hold slow sellers or seasonal items until demand picks up, move them to another sales channel, or send them back into FBA when the timing is right.
Can one 3PL inventory supply Amazon, Shopify and Walmart?
Yes. Inventory stored at a 3PL isn’t tied to one marketplace, so the same stock pool can replenish FBA, fulfill Amazon FBM orders and ship orders from Shopify, WooCommerce, Walmart, TikTok Shop or B2B buyers. That means less total inventory and fewer stockouts on one channel while another is overstocked.
