Amazon's Inventory Storage Fee Explained

by Dirk Llorens Oct. 22, 2021

If you’re selling products on Amazon, being able to use their robust system for pick and pack is a hugely beneficial aspect of being a third-party seller.

The “FBA” or “fulfilled by Amazon” program is incredibly popular and allows third parties to ship products to Amazon in bulk, and orders are processed by Amazon’s warehouse employees. The system is automated and it is easy to see why so many people opt for this method of fulfillment.

The third-party seller share on Amazon has continued to grow, and there are thousands of sellers taking advantage of FBA.



However, there are some downsides, and some extra fees incurred. In this guide, we’re explaining the inventory storage fees that Amazon imposes on sellers.



Why Do I Have to Pay Fees?



It’s just the cost of doing business with Amazon.

These seller fees make sense, and you’ll struggle to find other warehouse facilities that don’t charge fees for using their space and services.

Amazon charges inventory storage fees to protect their business model, too. Without, there would be no incentive for sellers to either remove their products from sale or make them available at a knock-down price to shift the stock.

Warehouse space is a business commodity, and Amazon centers are growing rapidly. Check out the distribution of these fulfilment centers and warehouses.

If you weren’t paying fees then Amazon would be storing your unsold stock for free, and this is not their business model.



How Amazon Inventory Storage Fees Are Calculated



How are the fees you pay worked out? If you have stock sitting in one of the Amazon fulfillment centers then you need to know, and it is essential that you take this into account with your financial forecasting. You may be surprised at how this can impact the profitability of a product.

The following aspects are considered when working out inventory storage fees:

  • Product size tier. This is all about whether your product counts as a standard size or oversized product. There is a guide to product-size tiers here. Which category your item falls into determines the cost.
  • What time of the year it is. As you may expect, the product storage fees vary based on the different time of the year. In the months approaching Christmas, storage space becomes an even more valuable commodity, and Amazon needs the space.
  • Product volume. This is all related to the size of the products when they are packaged. The volume is measured in cubic feet. You can use your Monthly Storage Fees report on Amazon which will show you exactly what this product volume is.
  • How many units are stored. If your product is selling then this can be a tricky thing to work out at times. Amazon uses the average when it comes to daily units stored, so that you are only paying for the storage you use.
  • Whether your item classifies as dangerous. Certain items can be dangerous goods and this means that there is an extra consideration around the storage and more work for the teams in the warehouse to carry out.


Amazon shares the following example on their site to help you to establish the costs:


Fee per product = average daily units x volume per unit x applicable rate

Sample product

  • Size tier: Standard-size
  • Current month: July
  • Volume per unit: 0.05 cubic feet
  • Average daily units in storage: 100
  • Dangerous goods classification: Not a dangerous good


100 average units per month x 0.05 cubic feet per unit x $0.75 per cubic foot (standard-size rate in July) = $3.75 total monthly storage fees




Monthly storage fees are usually charged some time between 7th and 15th of the month. You’ll be charged for the previous month’s storage.



Long-Term Storage Fees



If you’re lucky, you will be able to sell through your inventory and not have to worry about long-term fees, but if your items are stored in the warehouse for more than 365 days then you will also be charged an additional fee.

Again, this is to encourage sellers to purge their items to make way for fresh stock, either through selling items off cheaply to shift inventory or even removing inventory from the warehouse altogether.

As you can see from the example above, you’re either charged based on the cubic-foot fee or the per-unit fee depending on which is bigger. It’s either $6.90 per cubic foot, or $0.15 per unit. If your units are low-priced items then the smaller end of the fees can cut into your profit. If your items take up a large amount of space then the long-term storage fees can make a huge difference.

Check out more of the details about the fee below, and how it is charged:

The Recommended Removal report is a tool that Amazon has put into place in order to help you to calculate the number of items you need to remove to avoid incurring any storage fees. It can warn you 30-days before you are going to incur the fees so you have a chance to take action and remove the products from the warehouse.



How to Avoid Long-Term Storage Fees



There are no exemptions from the fees. If you’re using the storage space then it is up to you to pay the fees. However, you can avoid long-term storage fees in many circumstances.

  • Make sure you don’t ship more items than you are likely to sell to Amazon. Having a huge surplus can mean paying fees.
  • Discount items using the Outlet plan on Amazon to try and sell through your stock before incurring fees.
  • Have items removed from the warehouse and liquidated if required.






Storage fees can be intimidating for a new seller. Fortunately, long-term fees are only applicable after a full year, and you will be warned beforehand. Good inventory management and sales forecasting are key to keeping these extra expenses to a minimum and maintaining your account health.
