Amazon Cut My FBA Capacity Limit: What It Costs Now

Amazon cut my FBA capacity limit and Q4 has already started. Before you open a case, two facts decide what this actually costs you.

What happens when Amazon cuts your FBA capacity limit

Your capacity limit is set per account and per period, in cubic feet, and you read it in Capacity Monitor inside Seller Central. When it drops, two things follow at once. Shipment creation stops at the limit, and the request you want to file does not help this month: Amazon's own answer in the forums is that capacity requests cannot be submitted for the period you are currently in, only for a future one.

That is the part sellers find out late. In a thread about a sudden drop in restock limit, sellers describe cuts of a third to a half inside a single period, with no notice.

The storage overage fee is not what you are paying

Most of the fear around a cut limit comes from a fee that no longer exists. Amazon eliminated the overage fee for storage effective July 1, 2024. If your on-hand inventory exceeds your capacity limit, there is no overage charge.

Fee guides published elsewhere still quote $10.00 per cubic foot per month for overage. That was the rate before July 1, 2024. There is no rate now, because there is no fee.

What you do pay between October and December is the ordinary monthly storage rate at its Q4 level, which is a different line entirely. Those numbers are in the October jump in FBA monthly storage.

Why the limit moved

Amazon does not publish a formula. What it does say, in its peak readiness guidance for FBA capacity limits, is that the October and November limits are built to allow roughly six months of inventory, that November limits appeared in Capacity Monitor in late August, and that in November and December fulfillment centers keep only limited slots to accept shipments because they are prioritizing order processing. So a limit that looks punitive on October 1 is often a receiving-capacity decision, not a verdict on your account.

The fix, step by step

1. Open Capacity Monitor and write down two numbers: the limit for the current period and the limit for the next one. Every decision you make this week runs on the second number.
2. Do not file a request for this month. Amazon states it will not accept one for the current period, and the case will close without changing anything.
3. Use Capacity Manager to request capacity for the next period. The tool works on a reservation fee that you specify, so decide what the extra cubic feet are worth to you before you bid.
4. If you cannot raise the ceiling, lower the occupancy. Removals and disposals free cubic feet, and in Q4 they are slow: start them before the peak receiving crunch, not during it.
5. Split the shipment. You cannot create a single shipment above the limit, but you can send what fits now and hold the rest against next period's limit.

How to keep it from happening again

The limit is a consequence of how fast your inventory turns, so the number to watch is not the limit itself. Watch days of supply, and watch the aged inventory quietly occupying the cubic feet you will want in November. The five clocks of FBA inventory management covers which of them start charging on their own, and every FBA fee with its effective date covers what each occupied cubic foot costs across the year. Amazon's 2026 referral and FBA fee update, effective January 15, 2026, confirms there are no new fee types this year: nothing came in to replace the overage fee.

One last thing on timing. In its 2024 peak guidance Amazon asked for inventory to arrive at fulfillment centers by October 19 to guarantee it was Prime badge-ready for Black Friday. The exact date moves every year, so check this year's in Seller Central. The shape does not move: the cubic feet you want in November have to be requested in October, and the units have to be in transit before the limit becomes the problem.
