Dead-zone checker
Is this price inside an Amazon fee "Dead-zone"?
Check whether an Amazon selling price sits inside a fee dead zone — referral cliffs and fulfilment price bands — and where the nearest clear price is. Cliff and marginal tiers are read from Amazon's published wording, per marketplace and category.
Open this tool → 02Size-tier proximity checker
Which FBA size tier is this product in, and how close is a cheaper one?
Resolve an FBA size tier from real dimensions and weight, and see how far the product is from the next cheaper tier — per marketplace, including Ireland's own grid and the three US grids.
Open this tool → 03Low-Price FBA eligibility checker
Does this product qualify for Amazon's Low-Price FBA rates?
Check Low-Price FBA eligibility on the figure Amazon actually tests — the price including VAT — per marketplace and category, including the category exception thresholds.
Open this tool → 04Removal and exit-cost comparator
What does it cost to get this stock out of Amazon?
Compare Amazon's published exit fees per unit for one product, per marketplace. The routes on offer differ by region, and so does the per-kg or per-lb arithmetic behind each fee.
Open this tool → 05Break-even ACOS checker
What ACOS can this product afford?
Compare a product's break-even ACOS against the launch advertising benchmark for its category and marketplace. The ratio is arithmetic; the benchmark is the judgement.
Open this tool →Every answer declares itself
Each one names the currency, the marketplace, the data year and any figure that was assumed rather than supplied by you — and says plainly when a benchmark is not calibrated for your market.
