E-Commerce Profit & VAT Simulator (OSS)

Sellers shipping to consumers in other EU countries often calculate margins with their domestic VAT rate — and are surprised by the OSS return later. Since the EU-wide €10,000 threshold, B2C supplies carry the VAT of the target country: the same €29.99 gross price contains 19% VAT in Germany but 27% in Hungary — with an identical selling price, net revenue shrinks noticeably. At the same time, marketplaces charge their commission on the gross price including tax, so both effects compound. This simulator makes the relationship transparent: enter gross price, item cost, shipping and other costs, pick platform and target country — the tool splits the selling price into VAT, platform fee, costs and true net profit. All fee rates are deliberately stored as approximate values; results are an orientation aid and no substitute for tax advice.
