What is the Amazon FBA Profit Calculator?
An Amazon FBA calculator estimates how much you earn per unit when Amazon stores and ships your product. The main deductions are the referral fee (15% in most categories, minimum $0.30), the FBA fulfilment fee based on size tier and shipping weight, monthly storage ($0.78 per cubic foot Jan–Sep, $2.40 in Q4), plus your product, inbound shipping and PPC costs.
Enter your product's weight and size tier to get an estimated fulfilment fee, or override it with the exact fee from Seller Central.

Frequently asked questions
What is a good ROI for Amazon FBA?
Many sellers look for at least 100% ROI on product cost and a 20–30% net margin after PPC.
How is the FBA fee calculated?
By size tier (small standard, large standard, bulky, extra-large) and shipping weight — the greater of actual weight and dimensional weight (L × W × H ÷ 139).
Does this include the low-price FBA rate?
The estimate uses standard rates for items priced $10–$50. Items under $10 receive a discount, and apparel uses a separate rate card — override the fee if needed.
