About Arbitron
Analyze any Amazon product in seconds, or a whole supplier list in one pass. Arbitron shows you profit, ROI, demand and risk right on the Amazon product page and turns full wholesale catalogs into a clear list of what is actually worth buying.
Built in Germany for the European marketplaces (DE, UK, FR, IT, ES), with the real fees, VAT rates and risk signals that generic tools get wrong over here.
ANALYZE A SINGLE PRODUCT
See margin, ROI and profit directly on the Amazon page, calculated with your own costs.
OR SCAN AN ENTIRE SUPPLIER LIST
Upload a CSV, Excel, Numbers or ODS file, or just paste a supplier email. Arbitron reads out ASIN, EAN, UPC, ISBN and your purchase price automatically and checks every item across all your selected markets.
PRECISE PROFIT CALCULATOR
Real Amazon FBA fees pulled directly from Amazon, fully adjustable. FBA or FBM, prep costs, storage duration and VAT all flow into your calculation, not rough estimates.
RISK SIGNALS BEFORE YOU BUY
Warnings for IP and PL issues, Amazon selling on the listing itself, single-seller monopolies, strong price swings and products that are much cheaper on Idealo.
INTEGRATED KEEPA CHARTS
Price, BSR and Buy Box history over 30, 90, 180 and 365 days, so you see whether a price actually holds.
No Amazon seller account needed. Start your free trial and see what is worth buying before you spend a cent.
