FBA inventory storage overage fees

Effective August 1, 2020, overage fees are charged when your inventory in Amazon’s fulfillment centers exceeds your storage limit during any day of the month. These are in addition to monthly inventory storage fees and, if applicable, long-term storage fees. We strongly encourage you to avoid the overage fees by taking action to lower your inventory and remain within your storage limit.

Overage fees applicability

If you have a Professional selling account in the United Kingdom, the Netherlands, Italy, Spain, Germany, or France, overage fees apply if you have exceeded your current volume limits for a given storage type by the end of the day for any day in a given month. This charge will occur even if your inventory was subsequently reduced to a level below your storage limits allocated for that month. Refer to the overage fee calculation example for more details.

Overage fee calculation

The overage fee is based on how many days your storage limits are exceeded. This charge will occur even if your inventory was subsequently reduced below your storage limits allocated for that month. It will be charged monthly at €320 per cubic meter (excluding taxes) based on the daily average volume (measured in cubic meters) for any space your inventory occupies in Amazon fulfillment centers beyond your storage limits.

The volume measurement is based on unit size when properly packaged and ready to ship in accordance with FBA policies and requirements. Amazon reserves the right to measure or weigh packaged units or representative samples and to determine the storage type. In the event of any conflict between an Amazon measurement and information provided by the seller, Amazon's measurement will govern.

The following example illustrates how the overage fee is assessed and charged (all the fees below exclude taxes):

Event (with dates)	Sample values
Seller’s inventory exceeds their volume limit on August 1
	Inventory Performance Index	280
	Original standard-size storage limit	33.6 cubic meters
	New standard-size storage limit	28 cubic meters
Inventory storage overage fee accrues (August 1)
The seller’s inventory currently exceeds their standard-size storage limit by 2.8 cubic meters. An overage fee of €320 per cubic meter, or €896 total, will be incurred if no action is taken. (The overage fee will be assessed and charged in September.)	Standard-size storage limit	28 cubic meters
	Space taken by existing standard-size inventory	30.8 cubic meters
	Current standard-size overage	2.8 cubic meters
	Potential overage fee:	€896
Seller reduces inventory exceeding limit (August 5)
The seller creates a removal order for 2.2 cubic meters of standard-size inventory on August 5. No other standard-size inventory is sold or removed during August.	Standard-size overage, August 1 – 4	2.8 cubic meters
	Standard-size removal, August 5	2.2 cubic meters
	Standard-size overage, August 5 – 31	0.6 cubic meters
Inventory storage overage fee billed (September 5)
The seller’s average overage for the month was 0.88 cubic meters. They will be charged €320 per cubic meter for an August total of €282.	August average standard-size overage	0.88 cubic meter
	Storage overage fee per cubic meter	€320
	Total August storage overage fee	€282

In the example above, if the seller does not remove or sell through their inventory that exceeds the standard-size limit by September 1, they will begin accruing storage overage fees for September.

How can I determine which SKUs are contributing to my current usage for a storage type?

Current usage is a real-time representation of your in-stock inventory minus any pending removals. FBA Inventory Age provides a list of all of your active FBA listings, along with their storage type (standard-size, oversize, apparel, footwear, flammable, or aerosol) and how much volume the ASIN is taking up (available units x volume per unit = cubic meters). This information is also available via the Inventory Age report.

While the Inventory Age data is a good way to approximate current usage, it may not match your current usage value displayed in the storage monitor for a few reasons:

• Current usage is a real-time data source. Inventory Age report data may be delayed up to 72 hours due to data-processing times.
• Current usage includes unsellable inventory and excludes any units pending removal. These values are not included on the Inventory Age page and the associated report.
• Inventory that does not have an active listing may be counted in current usage (such as stranded inventory).

How do I interpret the Inventory storage overage fees report?

The Inventory storage overage fees report provides the inventory storage overage fees for each storage type and day your inventory in Amazon fulfillment centers exceeded your storage limits. This month-end report is available for download starting the second day of the following month.

You can download this report by following these steps:

• Click on the Reports tab in Seller Central
• Select Fulfillment by Amazon
• On the resulting page click on Inventory storage overage fees’ under ‘Payments’ section.

When will I be charged storage overage fees?

You will be charged applicable storage overage fees after the end of the month in which the fees were incurred. For example, let’s say that you exceeded your storage limit on August 1 and removed inventory to a level below your limit by August 5. On September 1, you would be charged for the four days that you were over the limit in August.

Will I be subject to overage fees if removal orders are paused or delayed?

Inventory for which you created a removal order will not be subject to an overage fee, even if the removal is paused or delayed.

If I have inventory in more than one marketplace, how do I calculate my total daily overage usage using the Inventory storage overage fees report?

You receive one daily storage limit that applies across the United Kingdom, Spain, Italy, France, and Germany marketplaces. For example, if your storage limit is 968 cubic meters for standard-size items (sortable), this represents your storage type limit for all five marketplaces combined. If the total storage type usage for a given day exceeds the network-wide storage type limit, you will be charged an overage fee for the inventory usage that exceeds your storage limit.

In the example below, the seller has standard-size (sortable) on-hand inventory in the United Kingdom, Spain, Italy, France, and Germany, with a daily storage limit of 968 cubic meters (UK is shown in cubic feet). To calculate the daily overage usage, convert to the volume unit you are most comfortable with.

Cubic meters to cubic feet conversion: 1 cubic meter equals approximately 35.315 cubic feet. To convert cubic meters to cubic feet, multiply the cubic meter value by 35.315.

Cubic feet to cubic meters conversion: 1 cubic foot equals approximately 0.028 cubic meters. To convert cubic feet to cubic meters, multiply the cubic foot value by 0.028, or divide by 35.315.

Below, the total overage usage is calculated using the values in the table.

1. Convert United Kingdom storage usage volume to cubic meters: 13,309 x 0.028 = 372.652 cubic meters
2. Round 372.652 to 373 cubic meters
3. Add marketplace storage usage for total storage usage: 373 + 90 + 51 + 15 + 572 = 1,101 cubic meters
4. Since the storage limit is 968 cubic meters, the seller has exceeded the limit by 133 cubic meters

Why do I have overage fee when I do not have any excess inventory?

If your existing inventory exceeds your storage limits for a given month, you will be charged an inventory storage overage fee. Storage limits are calculated based on available fulfillment center capacity, historical IPI scores, and your sales volume. For more information about how storage limits are determined, go to FBA inventory storage limits.

Excess (overstock), inventory is calculated based on a different set of rules. To learn more about excess inventory, go to Manage Excess Inventory. If you are over your storage volume limits but you do not have excess inventory, we suggest you reduce or remove your oldest or slowest moving inventory as soon as possible.

What if I believe I have been charged incorrect overage fees?

You can submit disputes if you believe that you have been charged incorrectly, up to 90 days from the dispute date the fee was applied to your account.

To be eligible for an overage fee reimbursement due to dimension disputes, go to Weight and dimensions policy.
