About Amazon Seller Fee Calculator
This free Amazon seller fee calculator helps FBA and FBM sellers accurately calculate Amazon's fees and determine net profit margins. Amazon charges two main types of fees: referral fees (8-17% of sale price depending on category) and fulfillment fees (FBA fees for size/weight or your own shipping costs for FBM).
Understanding Amazon's complex fee structure is crucial for pricing products competitively while maintaining healthy profit margins. Our calculator handles category-specific referral fees, FBA fulfillment costs, and helps you compare FBA vs FBM profitability to make the best fulfillment decision for your business.

- Professional: $39.99/month (unlimited sales, no per-item fee)
Break-even at 40 sales/month. Professional required for certain categories and advertising.
🎯 Example: $29.99 Product (Toys Category, FBA)
