Your bank says "commission-free" currency exchange. They're charging you 1-3.6% in the exchange rate markup. You just can't see it. This converter shows the mid-market rate and compares what Swiss providers actually charge — UBS, PostFinance, Neon, Revolut, Wise — side by side. On CHF 1,000 the difference between cheapest and most expensive provider is CHF 20-50. Monthly? That's hundreds per year. No signup. No ads. No affiliate bias.
