What is a foreign transaction fee?
A foreign transaction fee is what a card charges on top of a purchase with a foreign connection. This cheat sheet covers how to think about the fee, how it adds up and what to check before your team travels abroad. The detail is further down.
How to think about it
- Three things trigger it. A purchase in a foreign currency, a purchase in U.S. dollars made outside the U.S., or a purchase from a foreign merchant, including on its website.
- It's usually a percentage. The CFPB says the fee is usually a percentage of the purchase, withdrawal or other transaction, not a flat fee.
- Two parties can add to it. The fee can include the card issuer's charge plus a charge from a third party that performs the conversion, such as the card network.
- It's in the fee table. Card applications list it under "Foreign transaction." If a card has no fee, the issuer can drop the line or show none.
The math
Foreign transaction fee = the purchase in U.S. dollars x the card's fee percentage.
Illustrative only. A $500 hotel charge on a card where the network charges 1% and the bank adds 2% carries a 3% fee. $500 x 3%.
$15
The 1% plus 2% split comes from the CFPB's Regulation Z commentary. Your card's rate is in its cardholder agreement.
Before your team travels abroad
- Check the cardholder agreement. Not every card works outside the U.S., and the agreement shows the fee.
- Online orders count. Buying from a foreign merchant's website can trigger the fee, even from home.
- Dollars abroad count too. A purchase in U.S. dollars outside the U.S. can still carry the fee.
- Merchant conversion is separate. If the merchant converts the currency and adds its own fee, the card issuer doesn't have to disclose that fee.

Questions
Is a foreign transaction fee the same as a currency conversion fee?
The CFPB says a foreign transaction fee is sometimes called a currency conversion fee.
Can I be charged a foreign transaction fee on a purchase in U.S. dollars?
Yes. Regulation Z's example is a purchase in Bermuda paid in U.S. dollars, where the issuer charges a fee because the transaction took place outside the United States.
Do prepaid cards charge foreign transaction fees?
They can. The CFPB lists the foreign transaction fee among common prepaid card fees and says not all prepaid cards work outside the United States.
Where do I find my card's foreign transaction fee?
In the cardholder agreement. On a credit or charge card application, it appears in the fee table under the heading "Foreign transaction."
