Amazon FBA Calculator: Calculate Fees, Net Profits, and ROI

Understanding Amazon FBA Fee Components

To accurately calculate net margins for Amazon inventory, sellers must evaluate these fundamental cost variables:

1. Category Referral Fee

Amazon charges a category-based commission fee on every sold unit, typically averaging 15% across major retail categories.

2. FBA Fulfillment Fee

A flat rate charged per unit to cover picking, packing, shipping, and customer support. FBA fees vary depending on the unit's package dimensions and shipping weight class.

3. Inbound Shipping & Product COGS

The cost to manufacture or purchase the unit plus supplier freight shipment costs to Amazon fulfillment centers.

Amazon Profit Formula Reference

Total Amazon Fees = (Selling Price × Referral Fee %) + FBA Fulfillment Fee

Net Profit = Selling Price - (COGS + Inbound Freight + Total Amazon Fees + Ad Spend)
