The tool sorts your three dimensions, tests them against Amazon’s published standard and bulky tier limits, then uses unit or dimensional weight as the applicable tier requires. It selects the 2026 U.S. fee using your price, product type and season. The 3.5% fuel surcharge is shown separately so you can see the base rate.
This checker covers published standard and bulky packages up to 50 lb. It does not identify ASIN-specific exceptions, optional services, storage, inbound placement or aged-inventory fees. For a full order margin, continue to the Amazon FBA fee and profit calculator. To review existing products in bulk, use the Fee Preview audit.
