The biggest decision you’ll have to face as an Amazon seller is whether to fulfill the orders yourself or through FBA. Each option comes with pros and cons, but ultimately the decision should be based on the profits.  

In fact, fulfilling some products through FBA could result in very low to no profits, not to mention that in some cases it could even result in loss.

On the other hand, FBA comes with so many advantages that it’s impossible to just ignore it. So, how can you decide?

Luckily, Amazon practices a very transparent FBA fees policy. Moreover, you can also use an Amazon FBA calculator to check product profitability, margins, and estimated fulfilling fees when shipping your orders either through FBA or FBM.

1. Selling on Amazon FBA Fees

Before finding out how to calculate fees, you should understand why FBA is better than self-fulfillment and what fees the marketplace applies.

What is Amazon FBA?

FBA stands for fulfillment by Amazon and refers to a program where the marketplace manages your orders and fulfills them on your behalf. This comes with multiple benefits for both you and your buyers.

Some of the main advantages include:

  • No worries about inventory storage; your products will have their place in an Amazon warehouse.
  • No worries about packing and shipping your products, since Amazon will do all that for you.
  • No worries about customer service or returns. Amazon provides customer service for all FBA orders and manages returns on your behalf.
  • Eligibility to join Amazon Prime. Since Amazon has quick access to your products, your products are Prime eligible, so you can increase your customer pool.
  • Win buy box. As a Prime member, you’ll have more chances of winning the Buy Box.
  • Better customer engagement. Selling your products through FBA inspires more trust to customers, which ultimately results in more sales.

How Does FBA Work?

To join Amazon FBA, you will have to opt into the program from your Amazon seller central account. Then, you will have to pack, label, and ship your products to an Amazon warehouse.

All this is done through the seller central. Here, you’ll also have the possibility to track your inventory, set up alerts, and replenish your stock whenever needed.

If you don’t want to label your products, Amazon can do this on your behalf for an extra fee.

Now, the best part is that once the Amazon receives your items, they become immediately available for sale. From now on, you won’t have any other worries than watching orders flow and your profits grow. As it’s easy to imagine though, all this comes at a cost.

Amazon FBA Fees

Amazon calculates its FBA fees by weight and size of each unit you sell. They are broken down into two types of fees, fulfillment fees, and monthly inventory fees.

Fulfillment Fees

Are fees Amazon charges for handling your orders, including picking and packing the units, shipping and handling fees, customer service, and management of any product returns.

These fees are further divided into Standard-Size and Oversize.

Standard sizeFeeOversizeFee
Small 10 oz. or less$2.41Small 71 lbs. or less$8.26 + $0.38/lb. above first 2lbs
Small 10 – 16 oz.$2.48Medium 151 lbs. or less$9.79 + $0.39/lb. above first 2lbs
Large 10 oz. or less$3.19Large 151 lbs. or less$75.78 + $0.79/lb. above first 90lbs
Large 10 – 16 oz.$3.28Special oversize$137 + $0.91/lb. above first 90lbs
Large 1 – 2 lbs.$4.76  
Large 2 – 3 lbs.$5.26  
Large 3 – 21 lbs.$5.26 + $0.38/lb. above first 3 lbs.  

Clothing items, as well as items containing lithium batteries, incur further costs of $0.40 and $0.11 per unit respectively.

Monthly Inventory Fees

The second part of FBA fees you have to account for is the monthly inventory storage fee. These are calculated by the cubic foot, so the smaller your units and the more you sell, the less you’ll have to pay.

The factors that come into account when Amazon calculates your inventory storage costs are, in fact, the size of your unit, the daily average volume, as well as the season.

These fees are also different for standard size and oversized products, and you can expect to pay:

Standard sizeFeeOversizeFee
Jan – Sept$0.69 per cubic footJan – Sept$0.48 per cubic foot
Oct – Dec$2.40 per cubic footOct – Dec$1.20 per cubic foot

All fees above refer to standard FBA fulfillment, but you also have other options. Besides the standard program, Amazon also offers:

  • Multi-channel fulfillment: Allows you to sell products on your e-commerce and fulfill them via Amazon.
  • FBA Small and Light: Is a program designed for sellers who sell small, lightweight and inexpensive products with a price point of $15 or less. These reduced FBA fees come as an option for sellers who wouldn’t have adhered to FBA otherwise.
  • FBA Subscribe & Save: Is a program designed to help sellers enhance customer retention. You can enroll to offer discounts on eligible FBA products to repeat customers.

Each of the three alternative programs mentioned above comes with different fulfillment fees and may open the door to new opportunities.

Besides FBA, you could also opt to fulfill your own orders. You won’t have to pay any fees to Amazon, but this solution could be costlier unless you’re selling very small items you can store in your home.

To decide which fulfillment option is the most profitable, you can use one of the many Amazon FBA calculators.
