Amazon changes its fees from time to time, and some categories have tiered rates or minimum fees. Confirm the rate for your category in Seller Central before you rely on it.
The fba.tools FBA Profit Calculator gives Amazon sellers an accurate picture of their true net profit per unit — after every cost is accounted for. Most sellers underestimate their costs because they only think about product cost and the headline Amazon fee.
The reality includes referral fees, FBA fulfilment fees, PPC ad spend, inbound shipping costs, and VAT liability if you're registered. This calculator handles all of it in real time, using the latest 2026 fee schedules. No subscription, no data cap — open it and use it.
