Every FBA tool a UK Amazon seller needs, free and updated for 2026. From profit calculation to VAT liability to fee breakdowns — built around Amazon.co.uk's current fee schedule, in pounds sterling.
The UK suite currently includes the FBA Profit Calculator — the most-used tool for UK sellers, giving you real-time net profit after referral fees (8–15% by category), FBA fulfilment fees (from £1.98 to £9.15+ by size tier), VAT at 20%, and ad spend. Coming soon: a UK VAT Calculator covering registration thresholds, flat rate scheme, and fee VAT reclaim; an ACoS Calculator for PPC break-even analysis on Amazon.co.uk; a Restock Calculator using UK sales velocity; and a full Fee Breakdown tool by category and size tier.
Most FBA tools are built for the US market. Our UK FBA tools are built specifically for Amazon.co.uk — GBP by default, UK referral fee categories, UK FBA fee tiers, and VAT logic that reflects how the UK system actually works. We update our fee data within 24 hours of any Amazon UK change. No account, no paywall, no subscription — just open a tool and use it.
