Storage fees are based on the daily average volume (measured in cubic feet) for the space your inventory occupies in fulfillment centers. The volume measurement is based on unit size when properly packaged and ready to ship in accordance with FBA policies and requirements.
Note: Amazon may verify the weight and dimensions of a product using representative samples. Amazon’s information about a product’s weight and dimensions will be used to calculate fees if there is a difference between Amazon’s information and a seller’s information. Amazon may change its information about a product’s weight and dimensions from time to time to reflect updated measurements. Fees based on the weight and dimensions of a product are calculated using Amazon’s information about the weight and dimensions of that product at the time the fee is calculated.
Monthly inventory storage fee
Monthly inventory storage fees typically are charged between the 7th and 15th day of the month following the month for which the fee applies. For example, to see your inventory storage fee for January, refer to the February Payments report for transactions from February 7-15.
Fees vary by product-size tier and by month. Although standard-size products are often smaller than oversize products, they require more complex and costly shelving, drawers, and bins for storage. Fees are charged by cubic foot, however, so overall storage fees for standard-size products may be less than those for oversize products, based on volume.
Long-term inventory storage fee
A long-term storage fee applies to units that have been stored in an Amazon fulfillment center for more than 180 days.
The long-term storage fee is in addition to the monthly inventory storage fee. If you submit a removal order for inventory before the cleanup date, that inventory won’t be subject to long-term storage fees.
For more information, see FBA long-term storage fees.
