Foreign transaction fees are between 1 and 3% of the transaction depending on your credit card issuer and payment processing network (Visa, MasterCard, Discover or American Express). Some card issuers charge a base fee plus a percentage of the transaction. Some premier credit cards don't charge a fee at all. In 2006, some of the major credit card issuers had to pay a settlement to cardholders because the issuers hadn't told cardholders they would be charged a fee. Now these fees are disclosed in the credit card agreement. Read your credit card agreement to find out the exact fee your credit card issuer can charge.
