Understanding Storage Fees

Amazon FBA storage fees are important for sellers when using Amazon Fulfillment’s service. In 2023, these fees can impact your business’s profitability, so you must know the charges associated with storing your inventory in Amazon fulfillment centers.

Amazon calculates its FBA storage fees based on the size and weight of your products and the time of year.

Monthly storage fees for standard-sized items from January to September are $0.87 per cubic foot; from October to December, they increase to $2.4 per cubic foot. For oversized items, the fees are lower, at $0.56 per cubic foot from January to September and $1.4 per cubic foot from October to December.

Aged inventory surcharge storage fees are another consideration for your inventory within Amazon fulfillment centers. For items stored after 181 days, Amazon charges $0.69 per cubic foot starting from April 15, 2023, except for individual sellers, new sellers, and sellers with less than or equal to 25 cubic feet of daily volume.

To further understand your potential storage fees, Amazon provides an FBA revenue calculator to help you estimate your costs. You can input your product’s weight, dimensions, and category to obtain a detailed breakdown of the fees.

Here’s a quick summary of the key information regarding storage fees:

  • Monthly storage fees change depending on the size of the products and the time of year.
  • Standard-sized items have higher storage fees than oversized items.
  • Aged inventory surcharge applies to items stored after 26 weeks.
  • Amazon provides a calculator to help estimate your storage fees.

Different FBA programs, such as Amazon’s Small and Light program, can also impact storage fees, specifically designed for smaller, low-priced products. This program offers reduced fees in some areas, making it more appealing for specific product categories.

By understanding Amazon FBA storage fees, you can better plan your inventory management and budget accordingly to optimize your business’s financial performance. Remember that these fees can change over time, so always stay up-to-date on Amazon’s pricing policies.

FBA Storage Fee Calculation

Dimensional Weight

To calculate the dimensional weight, you need to measure your product’s dimensions (length, width, and height) and multiply them. Then, divide the product by 139 for standard-sized items and assumes a minimum width and height of 2 inches for oversize items. The result is the dimensional weight of your product, and it should be given in pounds.

Unit Weight

The unit weight of your product is simply its actual weight in pounds. Make sure to weigh your product, including any packaging, to determine the accurate unit weight.

Product Size

Amazon FBA categorizes items into two main sizes: small standard and large standard. These sizes are determined based on the product’s dimensions and weight. To classify your product, please refer to the table below:

Standard TiersWeightMaximum Dimensions
Small standardUp to 16 oz15″ x 12″ x 0.75″
Large standardUp to 20 lb18″ x 14″ x 8″
Oversized TiersWeightMaximum Dimensions
Small oversize70 lb or less60″ x 30″
Medium oversize150 lb or less108” (longest side)
Large oversize150 lb or less108” (longest side)
Special oversizeOver 150 lb>108” (longest side)

Products that exceed the maximum dimensions or weight of the large standard size are considered oversize. Oversize items have different storage fees and requirements than standard-sized items.

Now that you understand how to calculate dimensional and unit weights and identify the product size, you can determine your Amazon FBA storage fees. These fees are based on your product’s storage space in Amazon’s fulfillment centers. Storage fees vary depending on the item size and the time of year.

Amazon has two storage fee periods: January to September and October to December. The table below shows the storage fees for each period and size tier:

Size TierJan – Sep (per cubic foot)Oct – Dec (per cubic foot)

Remember that these FBA storage fees apply to items stored in Amazon’s fulfillment centers, and additional fees might apply, such as pick-and-pack or aged inventory surcharge fees.

Storage Fee Categories

FBA Storage

Standard Size

Amazon FBA storage fees are divided into two main categories: standard size and oversize. Standard-size items weigh less than 20 pounds and have a combined length, width, and height of fewer than 18 inches x 14 inches x 8 inches. Among standard-size items, there are two further classifications: small standard-size and large standard-size.

  • Small Standard-Size: Items with a length, width, and height not exceeding 15″ x 12″ x 0.75″.
  • Large Standard-Size: Items with dimensions less than 18” x 14” x 8”.

These items are typically less expensive to store in Amazon fulfillment centers, as they occupy less space. Storage fees for standard-size items vary based on the time of year and the amount of occupied storage.

Oversize items are those that exceed the dimensions or weight requirements for standard-size classification. They can be further divided into three subcategories:

  1. Small Oversize: Items with dimensions less than 60″ x 30″.
  2. Medium oversize: Items with the longest side fewer than 108″ and length + girth less than 130 inches.
  3. Large Oversize: Items with the longest side fewer than 108″ and length + girth less than 165 inches.
  4. Special Oversize: Items exceeding 108 inches or weighing more than 150 pounds and length + girth over 165 inches.

Oversize items typically incur higher storage fees, as they require more storage space. Like standard-size items, fees vary based on the time of year and the amount of occupied storage.

Knowing the storage fee categories and their respective costs can help you plan and optimize your product offerings cost-effectively. If you mainly deal with standard-size items, your storage fees will be lower, maximizing your profit margins. However, this is not to discourage you from selling oversize items, as they can also bring significant returns, but be aware of the potential impact on your inventory storage fees.

Monthly and aged inventory surcharge Fees

When you use Amazon FBA, it’s essential to understand the storage fees associated with your products. There are two types of fees you’ll encounter: monthly storage fees and aged inventory surcharge fees (earlier known as long-term storage fees).

Monthly storage fees are charged for your products’ space in Amazon’s fulfillment center warehouses. These fees depend on the product’s size and weight and the time of the year. Generally, storage fees increase during the peak holiday season from October to December.

Aged inventory surcharge fees apply to units stored in an Amazon fulfillment center for more than 26 weeks (181 days). These fees are in addition to the monthly inventory storage fees, and you’ll need to be aware of them to manage your aged inventory effectively.

To help you understand the breakdown of storage fees, here’s a table outlining the charges:

FBA monthly and aged inventory surcharge Fees

Amazon performs inventory clean-ups on the 15th of each month. Any inventory in the fulfillment center for more than 26 weeks is charged this fee starting from $0.69 per cubic foot. Remove items before the next inventory cleanup date to avoid aged inventory surcharge fees.

When calculating your storage fees, bear in mind that certain factors may affect the cost:

  • Logistics: The location of the fulfillment center and how well it is managed can impact storage fees.
  • Categories: Different product categories may have varying storage fees based on specific requirements.
  • Surcharge: Some items, such as oversized or dangerous goods, may incur additional fees.
  • Returns: If you experience a high number of returns, you may see an increase in storage fees.
  • Aging inventory: Monitor your aging inventory to avoid pricey fees.
  • Aged inventory surcharge: You may incur additional charges if your inventory ages over a specific threshold.

In summary, understanding your storage fees is crucial when using Amazon FBA. By keeping track of your inventory and monitoring fees, you can optimize your fulfillment strategy and manage your costs effectively.

Factors Affecting Storage Fees

When understanding Amazon FBA storage fees, several factors play a significant role in determining the costs. This section explores these factors and how they affect your storage fees.

Weight: One of the primary factors affecting storage fees is the weight of your inventory. Amazon calculates storage fees based on the total weight of your products in their fulfillment centers. The heavier your products, the higher the fees you’ll pay for storage. Remember that this is not only the actual physical weight of the items but may also include the packaging materials used to protect and ship them.

Dimensional Weight: Another crucial element is the dimensional weight of your products, which considers both the size and weight of your items. It’s calculated by multiplying the package’s length, width, and height and then dividing by a standard divisor. Dimensional weight can sometimes significantly impact storage fees more than the actual weight, especially for large, bulky items that take up more space in the warehouse.

Channels: Storage fees can also vary based on the channels you choose to sell your products through. For example, selling a product through Amazon’s FBA program may result in different storage fees than using their Merchant Fulfilled Network. Be sure to consider the cost implications of each channel before making your decision, as it can directly impact your overall storage expenses.

Unit Weight: Lastly, the unit weight of your products adds to the storage fees calculation for FBA inventory. This considers the total weight of an individual unit, including the packaging and any necessary materials for the shipping process. Remember that items with higher unit weights may incur higher storage fees due to their bulkiness or the need for specialized handling and packaging.

By taking the time to understand how each of these factors plays a role in calculating Amazon FBA storage fees, you can better anticipate your expenses and optimize your inventory management strategy accordingly. Utilize this knowledge to make effective choices when selecting products to sell, preparing your items for shipment, and determining the best sales channels for your business.
