Before the payout reaches your bank, Amazon deducts a fixed list from each FBA order. Here it is, line by line — and the moment you should look at this list is not when the monthly statement lands, but before you price the product.
The per-sale deduction checklist
Referral fee — a percentage of the sale by category: 15% for most, 8% electronics, 12% automotive, up to 45% device accessories; $0.30 minimum on most lines.
FBA fulfillment fee — size-tiered from the 2026 band card: small-standard bands from $2.43, large-standard bands from $2.91, priced by the greater of actual and dimensional weight.
Fuel & logistics surcharge — 3.5% of the fulfillment fee, applied since Apr 17, 2026.
Advertising — your PPC spend, billed by Amazon but controlled by you; treat it as a deduction anyway, because it is.
Returns — when a buyer refunds, the referral and fulfillment on that unit come back out, plus a processing fee.
Monthly storage — not per-order, but per inventory footprint: $0.78/ft³ off-peak, $2.40/ft³ in the Oct 15–Jan 14 peak.
Inbound placement fee — charged on inbound shipments (single-point splits: roughly $0.14–$1.90 depending on size); Amazon-optimized splits are free.
When this checklist means reprice
Run the list against your price in the calculator, then look at the net result. If net profit is at or below zero, your price is below break-even and every sale is a loss; if it sits under 15%, the SKU needs a higher price or a lower cost — not more traffic. The math is the same whether you sell one order a day or a hundred.
Remember the hidden two: inbound freight is not an Amazon deduction, but it comes out of the same pocket. Counting only Amazon's lines leaves $1.50/unit of the $30 example quietly unaccounted for.
Every FBA order deducts a referral fee (8–45% by category, $0.30 minimum), the FBA fulfillment fee (size-tiered in the 2026 bands), the 3.5% fuel and logistics surcharge on that fulfillment fee, plus any advertising spend. Storage bills monthly on inventory, and the inbound placement service fee applies to single-point shipments. Returns reverse the referral and fulfillment on refunded units.
