Founder, Aftermarket Arbitrage
Amazon doesn’t charge FBA fees on what your product weighs — it charges on the greater of the real weight and the dimensional weight (length × width × height ÷ 5,000). Most sellers have never heard of it, and it’s why a light product in a big box costs more to fulfil than you priced for. Enter your product below and get the real 2026 UK fee.
Figures transcribed from Amazon’s published UK FBA rate card effective 1 July 2026, including the 1.5% fuel & logistics surcharge applied from April 2026. This is the same fee table my sourcing engine uses to price every deal before my members see it. It’s a guide, not a quote — Amazon’s own fee preview in Seller Central is final.
