What's changing
Amazon says the per-unit increase over non-peak rates is the same as last year, about $0.32 on average, and that its 3.5% fuel and logistics surcharge applies on top of the peak fees. Peak rates for FBA and Remote Fulfillment with FBA are already in the Revenue Calculator, the Profit Analytics dashboard and the Fee and Economics Preview Report, so sellers can compare fulfillment types before the period starts. Storage is also higher in the fourth quarter: the Oct to Dec standard-size rate is well above the Jan to Sep rate.
Who's affected: Every seller shipping through FBA, Remote Fulfillment with FBA, Multi-Channel Fulfillment or Buy with Prime. Low-priced, high-volume products feel it most because the surcharge is per unit.
What to do about it
- Open the Fee and Economics Preview Report and check the peak rate for your top 20 SKUs.
- Rebuild landed cost, break-even ACoS and promotion floors for October 15 to January 14, then reset prices or ad targets where margin falls below your minimum.
- Trim slow-moving inventory before the higher Q4 storage rate adds to the cost of holding it.
