1. Storage fee per unit sold: Storage cost is monthly and cubic-foot based — most brands don't convert it to a per-unit cost in their P&L. A product holding 500 units at $0.78/cu ft with 0.08 cu ft/unit is paying $0.078/unit/month in storage. At 100 units/month sold, that's $0.39/unit of storage cost that never appears in the per-order fee breakdown.
2. Inbound placement fee: Since March 2024, Amazon charges $0.21–$0.27/unit for single-location inbound. It shows up in Payments 2 weeks after receiving — not in the shipment cost.
3. Refund administration fee: Amazon keeps 20% of the referral fee when you issue a refund. A 10% return rate on a product with a $4.50 referral fee costs you $0.90/return in admin fees that never appear in your normal per-unit breakdown.
4. Low inventory level fee: $0.32–$1.11/unit when you're understocked. Easy to overlook because it only triggers during supply chain crunches.
5. Aged inventory surcharge: Easy to miss if you're reviewing fees monthly and inventory only crosses day 181 mid-period.
6. Fuel surcharge: Added April 17, 2026. Brands running models from Q1 2026 may not have updated for this.
7. Inbound defect fee: 1,600% higher in 2026. Brands using 3PLs with unchanged SOPs are getting charged without knowing why.
