Comparing FBA vs FBM for Amazon, which is right for you?

What is the difference between FBA vs. FBM?

If you’re selling on Amazon, understanding storage fees is crucial to managing your costs. The following will assist you in understanding the storage fees for both FBA and FBM sellers. 

FBA (Fulfillment by Amazon) Storage Fee Structure 

When you choose FBA, you’re essentially hiring Amazon as your warehouse manager, shipping department, and customer service team. This service can significantly reduce your operational burden. The FBA Storage Fee Structure consists of monthly inventory storage fees and long-term storage fees. These fees cover the cost of storing your inventory at Amazon’s fulfillment centers and depend on factors such as product size, volume, and how long you store your products at the warehouse.  

Monthly Inventory Storage Fees

The monthly inventory storage fees are calculated by the amount of space that your products occupy in Amazon’s fulfillment centers. This is calculated by the average daily volume of your inventory in cubic feet. The factors that influence this fee include: 

• Product type 

• Product size-tier (small standard, large standard, oversized) 

• Standard sized items storage fees range from $3.43 to $7.17 for apparel items with additional charges based on weight. 

• Oversized items, are defined as products measuring over 130 inches in combined length and girth, incur higher storage fees and may lead to inventory surcharge fees. 

• Time of year or seasonality  

• For example, during off peak seasons like January to September, storage fees are reduced by $0.09 per cubic foot. Whereas, during October to December, which is peak season, the rates can be up to 2-3 times higher. (However, storage fees for oversized items remain unchanged regardless of which season it is). 

• Storage Utilization Surcharge 

To better manage your storage fees, you should bear in mind the possible costs and charges that may accumulate over time as your inventory changes.
