Good Margin

Good Margin is a margin calculator for retailers who price physical products across currencies. Cost in one currency, sale in another, with VAT, freight, and duties handled for you — all flowing into one number you can trust. Each product is a card in your wallet. Type the numbers, see the margin in big, colour-coded numerals. Costs change, the FX rate shifts, and you bump retail by ten euros — the margin updates live. — What's inside — • Live FX rates from the European Central Bank, cached for offline use • 23 currencies — pick the ones you actually use • VAT, freight % of cost, duties % of cost+freight — handled automatically • Wholesale price auto-derived from retail and your markup (or vice versa) • A breakdown dial showing exactly where each unit of retail goes: cost, freight, duties, VAT, margin • Price-sensitivity slider: drag to see what a different retail price would do to your margin, then commit it with a tap • Colour-coded margin tiers you set yourself — red, yellow, grey, green • Syncs across your iPhone, iPad, and other devices via iCloud — Built for — • Independent designers and brand owners • Buyers and merchandisers • Wholesalers • Anyone pricing across currencies who's tired of spreadsheets — Private by design — No account, no login, no tracking, no ads, no in-app purchases. The only network call is to fetch FX rates from a public ECB endpoint. Your numbers never leave your devices except via your own iCloud account.
