Calculating Amazon Seller Fees

Amazon charges various fees to sellers for using its platform and services. The primary fees include:

Referral Fees

Referral fees are commissions paid to Amazon for each product sold. These fees typically range from 6% to 45% of the product’s selling price, depending on the product category.

Fulfillment Fees (FBA)

For sellers utilizing Fulfillment by Amazon (FBA), fulfillment fees are charged based on the size and weight of the product, as well as the storage duration in Amazon’s fulfillment centers.

Subscription Fees

Amazon offers two types of seller accounts: Individual and Professional. Individual sellers pay a per-item fee for each sale, while Professional sellers pay a monthly subscription fee.

Additional Fees

Amazon may also charge additional fees for optional services such as Amazon Advertising, storage fees for excess inventory, and fulfillment fees for multi-channel fulfillment.

Example: Calculating Seller Fees

Let’s consider an example to illustrate how seller fees are calculated:

  • Product Category: Electronics
  • Selling Price: $100
  • Referral Fee Rate: 10%
  • FBA Fulfillment Fee: $5.00

Referral Fee: $100 (Selling Price) x 10% = $10.00 FBA Fulfillment Fee: $5.00

Total Seller Fees = Referral Fee + FBA Fulfillment Fee Total Seller Fees = $10.00 + $5.00 = $15.00

Identifying and Managing Expenses

In addition to seller fees, sellers incur various expenses associated with running their Amazon business. These expenses may include:

Cost of Goods Sold (COGS)

The cost of acquiring or manufacturing the products being sold, including raw materials, production costs, and shipping fees.

Shipping Costs

Expenses incurred for shipping products to Amazon fulfillment centers, as well as outbound shipping costs for fulfilling customer orders.

Inventory Storage Fees

Fees charged by Amazon for storing inventory in its fulfillment centers, based on the volume and duration of storage.

Amazon Seller Tools and Services

Costs associated with using third-party seller tools, software subscriptions, advertising services, and professional services.

Returns and Refunds

Costs associated with processing returns, issuing refunds, and handling customer inquiries related to product defects or dissatisfaction.

Example: Calculating Total Expenses

Let’s continue our example and calculate total expenses for selling the product:

  • Cost of Goods Sold (COGS): $50.00
  • Shipping Costs: $10.00
  • Inventory Storage Fees: $2.00
  • Amazon Seller Tools Subscription: $20.00

Total Expenses = COGS + Shipping Costs + Inventory Storage Fees + Amazon Seller Tools Subscription Total Expenses = $50.00 + $10.00 + $2.00 + $20.00 = $82.00


Understanding and accurately calculating Amazon seller fees and expenses is essential for financial management and success as a seller. By diligently tracking and analyzing these costs, sellers can make informed decisions, optimize profitability, and build a sustainable business on Amazon’s platform. Continuously monitor and evaluate expenses, explore opportunities for cost reduction and efficiency improvements, and leverage data-driven insights to drive growth and profitability in the competitive world of e-commerce.
