Nothing quietly drains a travel budget like paying badly abroad — surprise foreign transaction fees, terrible airport exchange rates, and the "would you like to pay in your home currency?" trap. The fix is a few simple habits: use a card without foreign fees where you can, always choose the local currency when a machine asks, and get cash from a bank ATM rather than a currency booth.
Foreign transaction fees
- What they are: many cards add a percentage fee on purchases made in another currency. Over a trip that quietly adds up.
- The fix: travel with a card that has no foreign transaction fees if you have one, and check your card's terms before you go. Some travelers also use a multi-currency card or account (for example Wise or Revolut) to hold and spend in the local currency.
- ATM fees: withdrawals abroad can carry both your bank's fee and the local ATM's fee — fewer, larger withdrawals usually beat lots of small ones.
Always choose the local currency (decline DCC)
When you pay by card abroad, the terminal or ATM may ask whether to charge in the local currency or your home currency. Picking your home currency triggers Dynamic Currency Conversion (DCC) — convenient to read, but it usually bakes in a worse exchange rate and an extra markup.
- Choose local currency — let your own card network do the conversion, which is typically better.
- This applies at ATMs too — decline the "with conversion" option.
🧳 Field note: This is the one card trick I never skip: whenever a terminal or ATM asks "pay in USD or local currency?", I always tap local currency. Choosing your home currency hands the exchange rate to the merchant's DCC system, and it's almost always worse — sometimes a few percent worse, on top of the fee. It feels helpful to see the price in dollars, but that convenience is exactly what you're paying for. Let your own bank do the math.
Cards vs cash — and where to get cash
| Method | Best for |
|---|---|
| Card / mobile pay | Most spending where cards are accepted; use a no-FX-fee card and pay in local currency. |
| Cash | Small vendors, markets, tips, transit and places that don't take cards. Keep some on hand. |
| Bank ATM abroad | Usually the best rate for local cash — withdraw at a reputable bank ATM, decline conversion. |
| Airport / hotel exchange booths | Convenient but often the worst rates — change only a small amount if you must. |
A common approach: bring a little local cash or get some from a bank ATM on arrival, put most spending on a no-fee card, and never let a terminal convert to your home currency. Keep cards and cash in more than one place — see the travel wallet guide.
🧳 Field note: I don't guess at how much cash to carry — I set a rough daily spend and multiply by the number of days, then scale it to the destination: a pricey city gets more, a cheaper country less. I pull most of it from a bank ATM on arrival (or order a little from my own bank before flying) rather than an airport exchange booth, and I split the cash across a couple of places so losing one stash isn't a disaster.
🧳 Field note: One of the first things I grab in a new city is a local transit IC card — Suica in Tokyo, Oyster in London, and equivalents elsewhere. You tap on and off instead of buying a ticket each trip, and in some places (Japan's Suica especially) the same card also pays at convenience stores and vending machines. Bonus: a physical card still works if your phone battery dies, and some spots give small IC-card discounts.
Before you go
- Tell your bank you're traveling (or set it in the app) so payments abroad aren't blocked as fraud.
- Check fees on your cards for foreign transactions and ATM withdrawals.
- Carry a backup card stored separately in case one is lost or blocked.
- Know the rough exchange rate so you can sanity-check prices and spot a bad DCC offer.
Paying abroad FAQ
Should I pay in local currency or my home currency?
Always choose the local currency. Paying in your home currency uses Dynamic Currency Conversion (DCC), which usually adds a worse rate and a markup. Letting your card network convert is typically cheaper.
What is a foreign transaction fee?
A percentage some cards charge on purchases made in another currency. It adds up over a trip. Using a card with no foreign transaction fees avoids it — check your card's terms before traveling.
Is it better to use cash or card abroad?
A mix. Use a no-fee card (paid in local currency) for most spending, and keep cash for small vendors, tips, transit and card-free places. How much cash depends on how card-friendly your destination is.
Where do I get the best exchange rate?
Usually a reputable bank ATM in the local currency (decline conversion), or a no-FX-fee card. Airport and hotel exchange booths tend to have the worst rates — change only a small amount there if needed.
Do I need to tell my bank I'm traveling?
It's a good idea — set a travel notice in your banking app or call — so foreign purchases aren't flagged and blocked as fraud. Also carry a backup card stored separately.
