Amazon FBA fees
Amazon FBA fees are the charges Amazon deducts when you sell using Fulfillment by Amazon — chiefly the referral fee (a category-based commission) and the fulfillment fee (a size- and weight-based pick, pack, and ship charge).
The referral fee is a percentage of the total sale price and depends on the category — most categories are 15%, with some lower (and a small per-item minimum). It applies whether you fulfill the order yourself or through FBA.
The fulfillment fee is a flat per-unit charge that depends on the product's size tier and weight: Amazon picks, packs, and ships the unit for you. On top of these, FBA sellers pay monthly storage fees (higher in Q4), and may incur long-term storage, returns processing, and removal fees.
Because these fees stack, the price a supplier quotes is never your real cost. A $25 sale in a 15% category loses $3.75 to the referral fee plus the fulfillment fee before product cost, prep, or shipping — which is why estimating fees accurately is the first step in any sourcing decision. The free FBA calculator does this for a single product; for a whole supplier file, Gridwinner runs the same size-tier model and folds the result into a real landed cost.
