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.
