Question 1

How are Amazon referral fees calculated?

Accepted Answer

Amazon charges a referral fee as a percentage of the total sale price (item price + shipping/gift wrap). Most categories are 15%, but some like Amazon Device Accessories (45%), Jewelry (20%), Watches (16%), and others vary. There is a minimum referral fee of $0.30 per item.

Question 2

What is the difference between FBA and FBM fees?

Accepted Answer

FBM (Fulfilled by Merchant) sellers only pay referral fees and optional fees. FBA (Fulfilled by Amazon) sellers additionally pay fulfillment fees (pick, pack, ship) based on item size and weight, plus optional monthly storage fees for inventory held in Amazon warehouses.

Question 3

Are these Amazon fee rates up to date?

Accepted Answer

The calculator uses approximate 2025-2026 fee schedules published by Amazon. Fees change frequently and vary by marketplace, size tier, weight, and category. Always verify the exact fee schedule on Seller Central before making pricing decisions.

Question 4

Does the calculator include monthly storage fees?

Accepted Answer

Optional — you can enter an estimated monthly storage fee per unit. Storage fees depend on the time of year (higher Oct-Dec), volume tier, and item size; the calculator does not auto-calculate them but lets you add a per-unit estimate.

Question 5

Is my pricing data private?
