Booking your spring break trip to Cancun soon? Here’s something to keep in mind: Almost every major credit card carries an “international conversion surcharge” of up to 5 percent on every purchase you charge in a foreign country. The fee isn’t listed separately on your bill so you wouldn’t even know anything fishy was afoot unless you memorized the exchange rate on the day of each transaction.
MasterCard and Visa each charge a 1 percent “processing fee” for international purchases, and American Express adds 2 percent. On top of that, the issuing bank is permitted to determine its own additional surcharge.
The sneaky fees have been going on for a few years now with most consumers unaware that they’re been gouged. In 2006, the New York Times first reported on the fees and experts advise consumers to know their credit cards’ policies on foreign purchases:
“Consumers will save a lot of money if they think about using the right card when traveling, and think about it in advance,” said Jennifer Openshaw, chief executive of Openshaw’s Family Financial Network and host of “Winning Advice with Jennifer Openshaw” on ABC Radio. “Using the wrong card can add close to 10 percent to the overall cost of a given purchase,” she said. “For example, your bank might charge you 3 percent for a purchase, and the merchant might charge 6 percent to convert the charge to dollars.”
ATMs are a handy way of getting cash out in the local currency (and saves you the hassle of travelers checks). While many banks will ding you there too with an “international cash withdrawal fee” averaging $5 per withdrawal, you’ll typically get the most favorable exchange rates.
