A foreign transaction fee is a surcharge your credit card issuer applies in two situations. First, when you purchase items outside the U.S., such as shopping or dining out while traveling. Second, you may pay a foreign transaction fee when making online purchases from a non-U.S. retailer that uses a different currency.
The rate varies depending on your bank, but it typically averages 3%. It may not seem significant for a single purchase, but it can quickly impact your wallet if you’re not careful. Understanding how it works, card options and if you can avoid it can help you make smarter financial choices.
