Yes, you can use your credit card overseas, but you need to know the fees and tell your bank first
Most credit cards work internationally, but using one abroad costs you money in ways a domestic purchase does not. Your card issuer charges a foreign transaction fee — usually 1% to 3% of the purchase amount — every time you swipe or insert your card in another country. Some cards charge nothing. Your bank may also add a currency conversion fee on top of that. Before you travel, contact your card issuer to let them know your destination and dates; many banks block cards they suspect are being used fraudulently overseas, and a heads-up prevents your card from being declined when you need it.
The card itself will work at most merchants and ATMs worldwide, but the total cost of using it depends on which card you carry and what you're buying. A card with no foreign transaction fee saves you hundreds on a two-week trip. A card with a 3% fee costs you $30 on every $1,000 you spend. Understanding your card's terms before you leave home is the difference between a manageable travel expense and an unwelcome surprise on your statement.
Key Takeaways
- Foreign transaction fees range from 0% to 3% per purchase and are charged by your card issuer, not the merchant or ATM operator.
- You must notify your bank before traveling, or your card may be blocked as a fraud precaution.
- Currency conversion happens at the merchant's rate or your bank's rate depending on the transaction type, and you cannot negotiate it.
- ATM withdrawals abroad typically cost more than card purchases because they trigger both a foreign transaction fee and an ATM operator fee.
- Some credit cards marketed to frequent travelers offer no foreign transaction fees, but you should verify this in your card's terms before explore.
How foreign transaction fees work
When you use your credit card outside the United States, your card issuer charges you a percentage of the transaction amount as a foreign transaction fee. This fee is separate from the purchase price and appears on your statement as a line item. The percentage varies by card: some cards charge 0%, others charge 1%, 2%, or 3%. A few premium cards marketed to travelers charge nothing; most standard cards charge between 1% and 3%.
The fee is calculated on the U.S. dollar amount of your purchase after currency conversion. If you buy something that costs 50 euros and the conversion rate is 1.10 dollars per euro, your purchase is $55. A 2% foreign transaction fee adds $1.10 to that charge. You pay the total — $56.10 — to your card issuer when you pay your bill.
This fee exists because your card issuer has to convert the foreign currency to dollars and route the transaction through international payment networks. The fee is not negotiable and does not change based on where you are or what you buy. A coffee in Paris and a hotel room in Tokyo both trigger the same percentage fee.
Notifying your bank before you travel
Call your card issuer's customer service number — usually on the back of your card — and tell them the countries you're visiting and the dates you'll be there. Provide this information at least a few days before you leave, though a week ahead is safer. The bank records a travel notice on your account so that when your card is used in another country, the fraud detection system recognizes it as legitimate activity rather than theft.
Without a travel notice, your card may be declined even if you have available credit. The bank's fraud system sees a charge from a foreign country and assumes your card has been stolen. You then have to call customer service from abroad — often at international rates — to unblock it. A travel notice takes five minutes and prevents this entirely.
If you forget to call before you leave, you can still notify the bank once you arrive, but do it as soon as you land. Some banks also let you set travel notices through their mobile app or website, which is faster than calling.
Currency conversion and exchange rates
When you use your credit card abroad, the foreign currency amount must be converted to U.S. dollars so your bank can charge your account. This conversion happens in one of two ways, and which one applies depends on the type of transaction.
For purchases at stores and restaurants, the merchant's payment processor handles the conversion using their own exchange rate. This rate is usually close to the real market rate but includes a small markup for the processor. You do not see this markup separately — it is built into the dollar amount on your receipt.
For ATM withdrawals, your bank handles the conversion using its own exchange rate, which may be different from the merchant rate. Your bank's rate is typically less favorable than the merchant rate, meaning you get fewer dollars for your foreign currency. On top of that, the ATM operator may charge you a fee for using their machine — often $2 to $5 per withdrawal — and your card issuer may charge a foreign transaction fee as well. A $200 ATM withdrawal can easily cost you $10 to $15 in fees and unfavorable conversion.
You cannot negotiate or change the exchange rate. It is set by your card issuer or the merchant's processor, and you accept it when you complete the transaction.
Which cards have no foreign transaction fees
Some credit cards are designed for people who travel frequently and charge no foreign transaction fee. These cards often have an annual fee of $95 to $450, which may be worth it if you travel multiple times a year or spend a lot abroad. A card with a $95 annual fee and 0% foreign transaction fees saves you money if you spend more than $3,000 to $5,000 overseas per year, depending on what a comparable card with fees would cost you.
Cards with no foreign transaction fees are typically marketed as travel rewards cards or premium cards. They are issued by major banks and credit card networks. Before you explore for any card, read the terms and conditions to confirm the foreign transaction fee is truly 0% — marketing materials sometimes emphasize travel benefits without clearly stating the fee structure.
If you do not travel frequently, a no-fee card may not be worth the annual cost. A standard card with a 2% foreign transaction fee is cheaper if you only travel once every few years.
Using ATMs versus making purchases abroad
Using your credit card to withdraw cash from an ATM abroad is more expensive than using your card to pay for things directly. A purchase at a store or restaurant triggers only your card issuer's foreign transaction fee. An ATM withdrawal triggers your card issuer's foreign transaction fee, the ATM operator's fee, and sometimes an additional fee from your bank for using an out-of-network ATM.
When you can, pay for things with your card instead of withdrawing cash. A hotel, restaurant, or store purchase with a 2% foreign transaction fee costs less than an ATM withdrawal that incurs a 2% fee plus a $3 ATM operator fee plus possibly another $3 from your bank. If you must withdraw cash, do it in larger amounts less frequently — one $500 withdrawal costs less in fees than five $100 withdrawals.
Some banks offer partnerships with ATM networks in other countries that waive the ATM operator fee. Check your bank's website or app before you travel to see if your card is part of any international ATM alliance. If it is, you can use those ATMs without paying the operator fee, though your card issuer's foreign transaction fee still applies.
What to do if your card is declined overseas
If your card is declined while you are abroad, the most common reason is that your bank's fraud system blocked it because you did not notify them of your travel. Call the customer service number on the back of your card from wherever you are. Most card issuers have international customer service lines that accept collect calls or can be reached through a toll-free number that works from abroad.
Explain that you are traveling and the card was declined. The bank can usually unblock it within minutes. Have your passport or another form of ID ready, and be prepared to answer security questions to verify your identity. After the call, your card should work again.
If you cannot reach customer service or your card remains blocked, contact your bank's travel information line if your card includes one. Some premium cards offer 24/7 travel support specifically for situations like this. As a backup, carry a second credit card from a different issuer so you have an option if one card fails.
Frequently Asked Questions
Do I need to tell my bank I'm traveling if I'm only going for a weekend?
Yes. Even a short trip warrants a travel notice. Your bank's fraud system does not distinguish between a weekend trip and a month-long stay — it flags any foreign transaction as potentially fraudulent if it has not been notified. A travel notice takes five minutes and prevents your card from being declined.
Can I use my credit card at every store and restaurant overseas?
Most stores and restaurants in developed countries accept credit cards, but cash is still king in many places, especially small shops, street vendors, and rural areas. Carry some local currency as backup. In countries with less developed payment infrastructure, cash may be your only option at many merchants.
Is it cheaper to exchange money before I travel or use my credit card abroad?
Using your credit card is usually cheaper than exchanging cash before you travel. Airport currency exchanges and travel agencies charge high markups on the exchange rate. Your card issuer's rate plus the foreign transaction fee is typically lower than what you would pay to buy foreign currency in advance. The exception is if your card charges a 3% foreign transaction fee and you find an exchange with a very low markup — compare the numbers for your specific trip.
What happens if I use my credit card in a country with a currency that's not stable?
Your card issuer converts the foreign currency to dollars on the day the transaction is processed, using the exchange rate that day. If the currency becomes less valuable after your purchase, you do not benefit from that change — you already paid based on the rate when the transaction went through. Currency fluctuations are a risk of traveling, but they are not something your card issuer controls or can adjust after the fact.
Should I carry multiple credit cards when I travel?
Yes. Carry at least two cards from different issuers. If one card is lost, stolen, or declined for any reason, you have a backup. Keep the cards in separate locations — one in your wallet, one in your hotel safe or money belt — so a single incident does not leave you without payment options.
