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.
Want the full picture on what fees do to a deal? Read my Online Arbitrage UK guide. The economics section walks through every cost line, including the ones most sellers forget.
This checker stops at the fulfilment fee, dimensional weight included. Not the referral fee, not the Digital Services Fee, not whether you can sell the brand. SellerAmp SAS covers that side on every retail page and Amazon listing you visit: profit and ROI after fees, sales estimates, eligibility and IP risk alerts. It’s what I put my members on.
