Amazon FBA Fee Calculator

The three that hit every FBA unit: the referral fee (a percentage of price, 15% in most categories), the FBA fulfillment fee (a fixed per-unit charge set by size tier and weight), and a monthly storage allocation per unit. It excludes occasional charges like inbound placement, returns processing and the aged-inventory surcharge; add an estimate for those if they apply to your catalog.

Pull the exact numbers, then add them up the way this FBA cost calculator does. The referral percentage comes from your category's fee schedule; the fulfillment fee comes from the Revenue Calculator or fee preview in Seller Central, which knows the product's real size tier; storage is cubic feet × the monthly rate. Precision matters: a 50-cent fee error is a full margin point on a $50 item.

Scope. This page totals what Amazon takes from a sale: referral, fulfillment and storage. The FBA profit calculator goes one step further and subtracts your product cost too, turning fee math into per-unit profit and margin. Use this one to sanity-check Amazon's cut and fee percentage; use the profit version when deciding whether a product is worth launching or reordering.

At least annually, and sometimes mid-year by category or size tier. Amazon has adjusted referral percentages, fulfillment fee tables and storage rates repeatedly, which is why every fee on this page is an editable field rather than a hardcoded rate. Before committing to a purchase order, verify the current numbers in Seller Central's fee schedule and re-run the math.
