The foreign transaction fee
Many U.S. credit and debit cards charge a foreign transaction fee, often around 3% of every purchase made in another currency or processed by a foreign bank. It shows up as a separate line on your statement or folded into the converted amount. On a $3,000 trip, that is about $90 just for using the card.
The fix is simple: many travel cards and some no-fee cards charge no foreign transaction fee at all. Check your card's terms or the rates and fees table before you go. The same fee can apply to online purchases from foreign sellers, even if you never leave home.

Say no to paying in dollars
At a restaurant in Mexico City or a shop in Paris, the card terminal may ask whether you want to pay in U.S. dollars. It sounds convenient, but this is dynamic currency conversion, and the exchange rate the merchant's bank uses usually includes a markup well above your card network's rate. Always choose to pay in the local currency. ATMs abroad often ask the same question: decline the conversion there too.
Check the rate you actually paid
To compare cards, do the math backward: divide the dollar amount on your statement by the amount in foreign currency on the receipt. The result is the exchange rate you actually paid. Compare it with the market rate for that day and you will see the real cost of your card, fees included.
Where else money disappears
- Cash advances: withdrawing cash with a credit card usually comes with a fee and interest from day one, with no grace period. Use a debit card at a bank ATM instead, ideally from a bank that reimburses ATM fees.
- Debit card fees: some banks charge a foreign transaction fee plus a flat ATM fee. Know both before the trip.
- Fraud blocks: most banks no longer need a travel notice, but turn on app alerts so you can confirm charges quickly if a purchase is flagged.
- A backup card: bring a second card, kept separately, in case one is lost or blocked.
Frequently asked questions
What is a foreign transaction fee?
A charge, often around 3%, that some cards add to purchases in another currency or processed abroad. Many travel cards do not charge it.
Should I pay in dollars or local currency abroad?
Local currency. Paying in dollars triggers dynamic currency conversion, which usually uses a worse exchange rate.
Is it a good idea to take cash out with a credit card abroad?
Usually not. Cash advances carry fees and start charging interest immediately. A debit card at a bank ATM is generally cheaper.
Do online purchases from foreign stores have the fee?
They can. If the seller or its bank is outside the U.S., your card may charge the foreign transaction fee even if the price is in dollars.
