When to pay in local currency vs your home currency abroad
Last updated by The EvenRound team.
The card terminal asks: 'EUR 40 or USD 44?' The wrong answer costs you 5%. Always.
Every international card transaction triggers the same question - implicitly or explicitly. Pay in the local currency of where you are, or pay in your home currency? It seems polite to pay in your home currency. It's actually expensive. Here's the rule: always pay in local. Always.
What's actually happening at the terminal
When the merchant offers to charge you in USD instead of EUR (or whatever local currency), they're invoking Dynamic Currency Conversion (DCC). DCC means the merchant - or rather, their payment processor - does the FX conversion at the terminal. They get to set the rate. Their rate is always 5-10% worse than your bank's.
Why DCC is a scam dressed as a service
Merchants and processors profit from DCC. They split the spread (5-10%) between themselves. The pitch is 'see the price in your home currency, no surprises'. The reality is you're paying a 5-10% surcharge for the privilege. Your bank or card provider always converts at a better rate.
How to recognise DCC
The terminal shows you two amounts: '€40' and '$44 (your home)'. Or it asks 'pay in EUR or USD?'. Or it just defaults to your home currency without asking. ATMs do the same - 'do you want to lock in this rate?' is DCC. Always say no, always pick local.
What if the menu is in your home currency?
Some tourist-area menus quote prices in your home currency for 'convenience'. The price they quote is at a terrible rate. Even if the menu says '$15', ask for the local price - it's usually €11-12. Pay the local price.
Edge cases
Two scenarios where DCC sometimes wins: (1) if your card has a 3%+ foreign transaction fee, DCC at 5% might be similar - but you should switch to a no-foreign-fee card instead. (2) Hotel pre-authorisations can lock in DCC unintentionally - check at check-in. The general rule remains: pay in local. The rare counterexample isn't worth thinking about.
Pay in local. Every time. Decline DCC. The 5% you save compounds across a trip into real money - usually €100-300 for a typical €5,000 group trip.
