FBA Storage Fees Explained - Tips, Tricks, & Strategies to Cut Costs

If you want to sell on Amazon using Fulfillment by Amazon (FBA), you might wonder how much it costs to store your inventory in Amazon's warehouses. FBA storage fees are one of the main expenses incurred by FBA sellers, and they can vary depending on the size, weight, and seasonality of your products. In this guide, we will understand the different aspects of FBA storage fees, how to calculate them, and how to reduce them with some tips and strategies.

TL;DR Summary - How Much Are Amazon FBA Storage Fees?

FBA storage fees are the fees that Amazon charges you for keeping your inventory in their fulfillment centers. It is calculated based on how many cubic feet of space your products occupy and is charged monthly.

FBA storage fees are split into two categories: standard size and oversize:

• Standard-size products can weigh up to 20 pounds and have 18 x 14 x 8 inches or less dimensions.
  ‍
• Oversized products that measure over any of the limits for standard-size products.

FBA storage fees also change depending on the season. Because of higher demand and competition among sellers, Amazon charges more storage fees during the peak season, usually from October to December. The peak season storage fees can be up to three times more than the rest of the year.

What Are FBA Storage Fees?

FBA stands for fulfillment by Amazon, and the FBA storage fee is the fee Amazon charges you for storing your goods in their fulfillment centers. The fee is calculated based on occupied space measured in cubic feet.

Amazon measures the amount of space your products take up by multiplying each unit's length, width, and height and then adding 0.25 inches on each side for packaging.

They keep updating the space your products take up every quarter based on the dimensions and weight data you provide or that they measure themselves. If there is a difference between your and Amazon's data, Amazon will use the bigger of the two to calculate the fees.

The FBA storage fee is charged on the 7th day of every month for the inventory stored in the previous month. For example, you will be charged for the inventory stored in January on February 7th.

You can see your FBA storage fees on your Seller Central account or download the Monthly Storage Fees report, which shows the details of your FBA storage fees by product and fulfillment center.

FBA Storage Fees vs. FBA Fulfillment Fees vs. Referral Fees

Sometimes, people confuse FBA storage fees for FBA fulfillment fees or FBA referral fees, but they are three different types altogether.

FBA fulfillment fee is the fee Amazon charges a seller for picking, packing, shipping, and handling orders. It is calculated based on your product's size, weight, and shipping speed and is unique for every product.

FBA storage fees also differ from FBA referral fees, which are the fees that Amazon charges you for selling your products on their platform. FBA referral fees are based on the category and the price of your products. They are calculated as a percentage of the sale.

Do FBA Storage Fees Vary by Product Size or Type?

Yes, FBA storage fees vary by product size and type. As mentioned earlier, Amazon divides your products into standard-size and oversized categories.

Oversize products have higher storage fees than standard-size products because they take up more space and need special handling.

Oversize products are further graded into four subcategories, each having its own fee structure:

• Small oversize
• Medium oversize
• Large oversize
• Special oversize

Here is a table that shows the criteria and fees for each product category and subcategory:

What Are FBA Long-term Storage Fees?

As an FBA seller, you want to keep your inventory levels optimal to meet customers' demands and avoid paying unnecessary fees. However, sometimes you have some inventory that sells slower than expected or is only in demand during certain seasons. In that case, you can be liable for paying extra fees for storing your inventory too long.

Amazon charges extra fees for FBA inventory that stays in their fulfillment centers for more than 365 days. These fees are called long-term storage fees and are charged in addition to the regular storage fees. Long-term storage fees are meant to encourage the sellers to sell their inventory faster or to remove it from Amazon's warehouses to free up space.

How Long Does Your FBA Inventory Last for Amazon to Start Charging Extra Fees?

Any item in your inventory that has been in the Amazon fulfillment center for more than 365 days is liable for the extra fees. This will be in addition to the monthly storage fees.

How Are Long-term Storage Fees Calculated?

The long-term storage fees are calculated depending on three factors:

• The dimensions and weight of your products
• The number of units that have been in Amazon's warehouses for more than 365 days
• Duration of storage of the products.

Amazon charges long-term storage fees twice yearly, on February 15th and August 15th. On these dates, Amazon will identify any units in their fulfillment centers stored for more than 365 days and charge you a fee of $6.90 per cubic foot or $0.15 per unit, whichever is greater.

Volume and Size of Inventory

The volume and size of your inventory are essential factors affecting your FBA and long-term storage fees. The volume of your inventory is the amount of space your products occupy in cubic feet.

The higher the volume and the larger the size, the higher the long-term storage fees. Therefore, optimizing the volume and size of your inventory is crucial.

Choose the proper packaging, reduce the dimensions and weight of your packaging, and select the appropriate product category to save on FBA storage fees and increase your profit margins.

Inventory Age

The inventory age of your products is the number of days that your products have been in Amazon's fulfillment centers. The inventory age of your products affects your FBA storage fees and long-term storage fees, as well as your inventory performance and sales rank.

The inventory age of your products is calculated from the date they arrive at Amazon's fulfillment centers until they are sold or removed. For example, if your products arrive at Amazon's fulfillment centers on January 1st and are sold or removed on January 31st, the inventory age of your products is 30 days.

Amazon divides your inventory age into six segments based on the number of days that your products have been in their fulfillment centers. These are:

• 0-60 days
• 61-90 days
• 91-180 days
• 181-330 days
• 331-365 days
• More than 365 days

You can check your inventory age report on Seller Central under the 'Reports' tab and the Fulfillment section. You can also download the Inventory Age report, which shows the details of your inventory age by product and fulfillment center.

Review the Fee Schedule

The fee schedule shows your products' current FBA fees and policies. It includes the storage, fulfillment, referral, and other fees you must pay as an FBA seller. It also consists of the product size and weight requirements, the inventory placement options, the removal and disposal options, and the service level agreements.

The fee schedule is updated periodically by Amazon to reflect the changes in market conditions, customer demand, and operational costs. Therefore, it is essential to review the fee schedule regularly, to stay informed of the latest FBA fees and policies, and to plan your budget and pricing accordingly.

You can find the fee schedule on Seller Central, under the Help tab, and then under the Selling on Amazon section.

Calculate

For example, if you have ten units of a standard-size product that measures 12 x 10 x 6 inches and it has been in Amazon's warehouses for more than a year, your long-term storage fee would be:

• Volume of one unit = 12 x 10 x 6 / 1728 = 0.417 cubic feet
• Volume of 10 units = 0.417 x 10 = 4.17 cubic feet
• Long-term storage fee = max($6.90 x 4.17, $0.15 x 10) = $28.77

You can check your 'inventory age report' on your Seller Central dashboard to find the number of units stored in Amazon's warehouses for over 365 days.

How Can I Track My FBA Storage Fees?
