Starting an Amazon business has become much easier, thanks to the FBA program. With FBA, anyone can sell goods on AMZ without having to worry about fulfillment.
FBA is a service Amazon offers third-party sellers. In this program, AMZ bears responsibility for inventory storage and order fulfillment. Third-party sellers send their inventory to a fulfillment center. Then AMZ picks, packs, and ships orders to customers. Amazon also handles customer service and returns on behalf of the seller.

The question on your mind now is probably, “how much does FBA charge?” And this is an important question. You need to know the costs involved so that you can price your items profitably. The good news is, we have answers. In this article.
What are Amazon FBA Fees?
AMZ charges for the services it provides to third-party sellers under its FBA program. They generally cover the cost of inventory storage, packing, and shipping. They also provide customer service and manage returns on your behalf.
There are two major fees that sellers have to pay: fulfillment and inventory storage fees.

- Inventory storage fees: This category covers the costs of storing your goods in a Fulfillment Center.

A Breakdown of Fulfillment Fees
Fulfillment fees are charged on a per-unit basis. Unlike referral charges, there are no Amazon FBA fee percentages or by category. FBA fulfillment fees are calculated based on a product’s shipping weight and size. The fulfillment charges for clothing items also differ from that of non-clothing items.
AMZ uses two major size tiers to determine fulfillment charges. They are standard size and oversize. And these size tiers have different sub-tiers.

FBA Fees: A Breakdown of Inventory Storage Fees
Inventory Storage fees: AMZ charges this based on the amount of space that your inventory occupies. Your inventory volume is calculated per cubic foot. Usually based on the size of the product after packaging and shipping.
There are two kinds of storage fees: Monthly inventory storage and long-term inventory storage fees.
- Monthly Inventory Storage fees: This type of inventory storage fee is charged monthly. AMZ charges this fee between the 7th and 15th day of the month following the month in which the fees were incurred.
- Long-term Inventory Storage fees: This fee is charged on items that stay in AMZs fulfillment centers for more than 365 days. AMZ deducts long-term inventory storage charges monthly. Usually between the 18th and 22nd day of each month.
Here’s a breakdown of the current fee structure for inventory storage:
Monthly Inventory Storage Fees
Monthly inventory storage charges vary based on seasonality. Thus, there are different monthly inventory storage fees. It is split into January to September, then October to December. Like fulfillment, AMZ uses standard size and oversize tiers to determine the fee rate. The fee structure for dangerous goods also differs from that of non-dangerous goods.
Here’s a breakdown of the current fee structure for inventory storage
Non-dangerous goods
Month | Standard Size | Oversize |
January – September | $0.75 per cubic foot | $0.48 per cubic foot |
October – December | $2.40 per cubic foot | $1.20 per cubic foot |
Dangerous goods
Month | Standard Size | Oversize |
January – September | $0.99 per cubic foot | $0.78 per cubic foot |
October – December | $3.63 per cubic foot | $2.43 per cubic foot |
Here, the charge for oversize products are lower than that of standard-size products. This is because standard-size products are smaller than oversize products. Also, their storage requires more complex and expensive shelving, drawers, and bins.

Long-term storage fees
Amazon deducts long-term storage charges at $6.90 per cubic foot or $0.15 per unit, whichever is greater.

How to Calculate Amazon FBA Fees
When starting an FBA business, it’s not enough to know the structure for the charges. You need to also calculate how much you will be paying as a seller charge for every product you decide to sell. Familiarizing yourself with FBA Costs is important. It will help you choose a product with high-profit potential. and guide you in pricing your products in a way that yields good profit margins.
Amazon provides a free calculator that you can use to estimate how much you’ll be paying as an FBA seller. The Calculator provides an estimate of your fulfillment costs and other seller fees. All you need to do is enter the price and cost of the product. The calculator also calculates your proceeds, net profit, and net margin.
The calculator allows you to compare the costs of fulfillment through FBA or FBM. This raises the question, “is FBA cheaper than FBM?”

FBM vs FBA Fees
The aim of every business owner, sellers included, is to earn a lot of profits while cutting costs. That’s why sellers want to know if it is cheaper to opt for FBA or FBM.
Unlike FBA sellers, FBM sellers do not have to pay any extra costs, since they fulfill orders by themselves. But, FBM sellers have to bear all the major costs. They’ll also have to handle customer service and returns.
Although FBM sellers do not have to pay any fees, the costs they incur are usually higher than FBA fees. This is because AMZ is a conglomerate. Hence, they have an advanced fulfillment infrastructure and distribution network. As a result, AMZ can negotiate lower shipping rates with logistics service providers.
There are other factors to consider before choosing a fulfillment option. Product size is an important factor. FBA is better suited for small and light items that sell fast. What if you sell heavy and expensive items that do not sell fast? You’re better off using the FBM model so that you don’t rack up hefty charges.
Well-established businesses can negotiate with reliable freight forwarders. So, FBM may be more beneficial in this case.
You can also use the Calculator to determine which fulfillment option costs less.
How to Reduce FBA Fees
The charges may seem like a small price to pay for the many benefits that you’ll enjoy from using FBA. But FBA charges can eat into your profits if you’re not careful. Here are some measures you can take to reduce your expenses:
- Sell small and lightweight items: Fulfillment and storage costs depend on the size and weight of the item. So, the lighter and smaller the product, the lower the fees costs you incur. Selling small, low-priced products qualifies you for the FBA Small and Light program. This program offers reduced fulfillment costs.
- Monitor Your Inventory Performance Regularly: Within your Seller Central account, you can assess your inventory performance. Use the Inventory Performance Index (IPI) score. Check for items that are not moving and take these off the warehouse. If you don’t, you will incur higher charges, called long-term storage fees.
- Check Your Invoices for Discrepancies and File the Appropriate Claims: Audit your invoices and look for discrepancies. Should you find any, you can file a claim for reimbursement. Keep in mind that there is a time limit for these and the deadlines depend on what type of claim you are filing. If your claim is proven valid, AMZ will reimburse the retail value of the affected inventory. So you earn back the profit that you would have made on that inventory.
- Remove any unfulfillable order returns from fulfillment centers: Order returns are inspected by Amazon and decide whether these can be resold. Products that are no longer in good condition are kept in the fulfillment center. As a result, they’ll continue to incur storage charges. Check the Inventory Health report in Seller Central. This way, you can see if you have any unsellable inventory. Then you can opt to have these destroyed or returned to you.
