How to Calculate FBA Fees

Amazon’s FBA program takes the hassle out of shipping and fulfillment – but it also comes with a price tag. If you don’t know exactly how those fees are calculated, you could be losing profit without realizing it. 

From storage costs to fulfillment and referral fees, every charge impacts your bottom line. 

This post will walk you through how FBA fees work, how to calculate them, and how to make smarter sourcing decisions as a result. Whether you're just getting started or already selling at scale, understanding your FBA costs is non-negotiable.

What Are Amazon FBA Fees?

Amazon FBA fees are the costs sellers pay to use Amazon's fulfillment network. These fees cover the platform's services – from storing your products in Amazon's warehouses to picking, packing, shipping orders, and handling customer service. While FBA helps automate logistics and scale your business, understanding the types of fees involved is critical to staying profitable.

Core categories of Amazon FBA fees

• Selling plan fees
• Referral fees
• FBA Fulfillment fees
• Storage fees
• Prep and shipping costs.

In addition to these, several other specific fees can apply depending on your inventory size, product type, or business model. Here’s a detailed breakdown of each.

Selling plan fees

To sell on Amazon, you must choose a selling plan:

• Individual Plan

$0.99 per unit sold; suitable for beginners or those selling fewer than 40 items/month.

• Professional Plan

$39.99/month regardless of volume. Ideal for regular sellers – it includes access to tools, analytics, and Buy Box eligibility.

Referral fees

These are Amazon's cut from each sale – a percentage of the total price (excluding tax but including shipping and gift wrap). Most categories fall between 8–15%, but some, like Amazon Device Accessories, can hit 45%. 

Other selling fees

• Closing Fees

$1.80 per item in media categories (Books, DVDs, etc.)

• High-Volume Listing Fee

$0.001 per SKU/month for over 1.5M SKUs.

• Refund Administration Fee

$5 or 20% of the referral fee – whichever is lower.

• Digital Services Fee

2–3% surcharge in countries with digital service taxes (UK, France, Italy, Spain, Canada, etc.).

Amazon FBA fulfillment fees

These fees cover the logistics of fulfilling orders and depend on product size, weight, category, and type.

Main FBA fulfillment fees

• Order Fulfillment Fees

Picking, packing, shipping, and customer service. Charged per unit, varies by apparel/non-apparel.

• Low-Price FBA

For items under $10, $0.77 cheaper than standard FBA.

• Inbound Placement Service Fees
  ‍
• Minimal Shipment Splits

Amazon redistributes from one center for a fee.

• Partial Shipment Splits

You handle distribution, no fee.

• Returns Processing Fees

Applied when return rates exceed thresholds (Apparel/Shoes have different rules).

• Low-Inventory-Level Fees

Triggered if stock level drops below a 28-day supply.

• Inbound Defect Fees

Charged for non-compliant shipments.

Amazon FBA storage fees

Storage fees are based on how much space your inventory takes up daily in fulfillment centers.

Types of storage fees

• Monthly Storage Fees

Rates vary by size, product type, and season (peak vs off-peak). Dangerous goods incur higher fees.

• Storage Utilization Surcharge

Applies to sellers using over 25 cubic feet of space with a high storage ratio.

• Aged Inventory Surcharge

For items stored over 180 days. Added monthly on top of regular storage.

• Overage Fee

Charged at $10 per cubic foot when you exceed monthly storage limits.

• Removal and Disposal Fees

Costs to return or dispose of aged or excess inventory.

Prep and shipping costs 

These are fees for preparation of the order and shipping it to Amazon’s fulfillment centers. Typically, sellers use third-party prep centers to prepare orders and send them to Amazon. 

Prep center fees

If you use a prep center, they charge for labeling, packaging, bubble-wrapping, and making your inventory FBA-compliant. Fees vary by provider and product type.

Shipping to Amazon fees

Also known as inbound shipping – this is the cost per unit to send your goods from your supplier or prep center to an Amazon fulfillment center.

How to Calculate Amazon FBA Fees

Calculating so many Amazon FBA fees can be challenging, but it's important to have a good understanding of how much it will cost to sell your products through Amazon FBA and ensure you will get enough profit.

Amazon sellers typically use FBA fee calculators to estimate their costs. These tools break down how much you’ll pay for fulfillment, storage, referral fees, and more. By factoring in selling plan fees, referral fees, FBA fulfillment fees, and storage fees, you can set competitive prices while ensuring you make a profit.

However, FBA calculators differ. They are used for different purposes and provide different levels of fee details. Also, they are not equally convenient. 

To estimate or find out your FBA fees, you can use a number of options. 

You can apply advanced third-party FBA calculators like Seller Assistant’s FBM&FBA Profit Calculator showing all Amazon fees right on the Amazon search and product pages and in the Side View panel on your supplier websites. You can also get bulk Amazon fee and cost calculations for thousands products as once with Seller Assistant's Price List Analyzer.

Another option is to use one of the two free Amazon fee tools: Inline revenue calculator in the Manage Inventory dashboard in your Seller Central, Amazon Revenue Calculator, and Amazon Fee Preview Report. However, some of these tools don’t factor in all FBA costs.

What Are Different Fee Calculators?

As said, the majority of Amazon sellers use FBA calculators to accurately calculate FBA fees.

Among them, Seller Assistant's FBM&FBA Calculator stands out – it lets you calculate Amazon fees both in bulk (if you have a supplier list with thousands of UPCs) and for individual products directly on Amazon and supplier pages, side-by-side with real-time profitability estimates.
