Using Your Credit Card Abroad: What Works and What Doesn't

Yes, you can use your credit card internationally, but you need to know the fees, currency conversion rates, and which cards work best in different countries

Most credit cards work outside the United States, but "works" doesn't mean it's cheap or convenient. Your card will likely be accepted at major retailers, hotels, and ATMs in most developed countries. The catch is that you'll pay extra charges — a foreign transaction fee (usually 1 to 3 percent of each purchase), a currency conversion markup, and sometimes an ATM withdrawal fee. Some cards charge none of these. Others charge all three. Before you travel, you need to know which fees your specific card charges and whether a different card might save you money on this trip.

The good news is that understanding these fees takes about fifteen minutes, and choosing the right card for your trip can save you hundreds of dollars over two weeks abroad. This guide walks you through how the fees work, which cards avoid them, and what to do if something goes wrong while you're traveling.

Key Takeaways

• Most credit cards charge a foreign transaction fee of 1 to 3 percent on purchases made outside the United States, plus a currency conversion markup that the card network adds on top.
• Some credit cards marketed to travelers charge zero foreign transaction fees, though you may pay an annual fee to hold the card.
• Withdrawing cash from an ATM abroad using your credit card often costs more than using a debit card, because credit card cash advances carry interest charges that start immediately.
• Notify your card issuer before traveling so they don't block your card thinking it's fraudulent activity, and ask them to confirm which countries your card will work in.
• Currency exchange rates are set by the card network (Visa, Mastercard, American Express), not by your bank, so shopping around for a "better rate" won't help — the rate is the same everywhere on a given day.

How foreign transaction fees and currency conversion actually work

When you swipe your card abroad, two separate charges happen. First, the merchant's bank converts the local currency to US dollars using the exchange rate set by your card network (Visa, Mastercard, or American Express). That rate is usually close to the real market rate, but the card network adds a small markup — typically 1 to 2 percent. Then your card issuer (your bank or credit card company) adds its own foreign transaction fee on top, usually 1 to 3 percent.

So if you spend 100 euros and the real exchange rate is 1.10 dollars per euro, you might expect to pay $110. Instead, you'll pay roughly $110 plus the network markup plus your issuer's fee — often totaling $113 to $115 depending on your card. That extra $3 to $5 is pure cost, and it adds up fast on a two-week trip. On a $2,000 vacation budget, these fees could easily total $60 to $100.

The card network's markup is the same no matter which bank issued your card. You cannot negotiate it or find a better rate elsewhere. What you can control is your issuer's foreign transaction fee. Some cards charge zero. Others charge 3 percent. That difference matters, and it's the main reason to compare cards before you travel.

Which cards charge no foreign transaction fees

Cards marketed as travel rewards cards often waive the foreign transaction fee entirely. Examples include the Chase Sapphire Preferred, the American Express Platinum, and various cards from Capital One and Discover. The tradeoff is usually an annual fee — often $95 to $550 — so these cards only make sense if you travel regularly or spend enough on other rewards to offset the fee.

Some cards charge no annual fee and no foreign transaction fee, though these are less common. Your card issuer's website will state the foreign transaction fee clearly in the terms and conditions. If you don't see it listed, call the customer service number on the back of your card and ask directly: "Does this card charge a foreign transaction fee?" Write down the answer and the date you called so you have proof of what you were told.

If your current card charges a foreign transaction fee and you travel often, it may be worth opening a second card specifically for international trips. You don't need to close your existing card. You can carry both and use the no-fee card abroad while keeping your regular card at home for everyday use.

Using ATMs abroad and why credit cards are expensive for cash

You can withdraw cash from ATMs in most countries using your credit card, but it costs significantly more than using a debit card. Here's why: a credit card cash advance is treated as a loan, not a withdrawal from your own money. Interest charges start accruing immediately — often at a higher rate than your regular purchase APR — and there's usually a cash advance fee of 3 to 5 percent on top. A $200 withdrawal might cost $10 to $15 in fees plus daily interest that compounds until you pay the balance.

If you need cash abroad, use a debit card instead. Debit card ATM withdrawals typically cost $2 to $5 per transaction, depending on your bank and the ATM operator. That same $200 withdrawal costs a fraction of what a credit card cash advance would. The money comes directly from your checking account, so no interest accrues.

The exception is if your credit card offers a 0 percent introductory APR on cash advances and waives the cash advance fee. These offers are rare and usually come with a short time window — often three to six months. Check your card's terms before you travel, and if you have this offer, read the fine print to see when the promotional rate ends.

Notifying your card issuer and checking which countries your card works in

Call your card issuer at least one week before you travel and tell them the countries you'll visit and the dates you'll be there. This prevents your card from being blocked as fraudulent when it's used in an unfamiliar location. Many issuers now let you set travel notifications through their mobile app, which is faster than calling and takes about two minutes.

While you have them on the phone or in the app, ask: "Will my card work in [country name]?" Some cards don't work in certain countries due to network agreements or sanctions. American Express, for example, is less widely accepted than Visa or Mastercard in some regions. Knowing this before you land means you can bring backup payment methods or open a second card before you leave.

Also ask for the customer service phone number that works internationally and write it down on a piece of paper. Keep this number separate from your card — in your luggage, your email, or a note on your phone. If your card is lost or stolen abroad, you'll need this number to report it quickly and prevent fraudulent charges.

What happens if your card is declined abroad

A declined card abroad usually means one of three things: the merchant's terminal doesn't accept your card network, the merchant's system thinks the transaction is fraudulent, or your card issuer has blocked the transaction. The first is most common in smaller towns or countries where one network dominates. In rural areas of some countries, Visa might work everywhere while Mastercard is rarely accepted.

If your card is declined, ask the merchant if they accept a different card network. If you only have one card, ask if they accept cash, a bank transfer, or a local payment app. Many small businesses in Europe and Asia prefer cash or local payment apps to credit cards, so having backup options matters.

If you're declined at multiple merchants in the same day, call your card issuer's international customer service line immediately. A fraud block can strand you without access to your money. This is why you wrote down that international number before you left — you'll need it now, and you'll be glad you have it.

Comparing credit cards, debit cards, and cash for international travel

Credit cards are best for large purchases (hotels, flights, rental cars) because they offer fraud protection and you're not spending your own money immediately. If a charge is fraudulent, you can dispute it and the card issuer investigates. Debit cards are best for ATM withdrawals because the fees are lower and interest doesn't accrue. Cash is best for small purchases in places where cards aren't accepted, and it's the only option if your card is lost or your account is frozen.

The ideal approach is to carry all three: a credit card with no foreign transaction fee for major purchases, a debit card for ATM withdrawals, and some local currency in cash for emergencies and small vendors. Before you leave, know the fee structure of each card, have your card issuer's international number written down separately, and set travel notifications through your bank's app or a phone call.

Frequently Asked Questions

Do I need to tell my credit card company I'm traveling?

Yes. Many card issuers monitor for unusual activity and will block your card if they see charges from a country you don't normally visit. Setting a travel notification takes five minutes through your bank's app or a phone call and prevents this. Even if your issuer doesn't block cards automatically, calling gives you a chance to confirm your card works in that country and get their international support number.

Will I get a better exchange rate if I exchange money before I travel?

No. The exchange rate your credit card uses is set by the card network on the day of the transaction. You cannot get a better rate by exchanging cash at an airport or bank beforehand. Airport currency exchanges typically charge higher markups than credit cards do. Your best option is to use a credit card with no foreign transaction fee and let the card network's rate apply.

What's the difference between a foreign transaction fee and currency conversion?

Currency conversion is the process of changing local currency to US dollars using an exchange rate. The card network does this and adds a small markup of 1 to 2 percent. A foreign transaction fee is a separate charge your card issuer adds on top, usually 1 to 3 percent. Both happen on the same transaction, so you pay both unless your card waives the foreign transaction fee.

Can I use my credit card to withdraw cash from an ATM abroad?

Yes, but it's expensive. Credit card cash advances charge interest immediately and usually include a 3 to 5 percent fee. A $200 withdrawal might cost $10 to $15 in fees plus daily interest. Use a debit card instead, which typically costs $2 to $5 per withdrawal with no interest charges.

What should I do if my credit card is declined while I'm traveling?

First, ask the merchant if they accept a different card network or payment method. If multiple merchants decline your card on the same day, call your card issuer's international customer service line immediately — a fraud block can freeze your account. This is why you should write down the international support number before you travel and keep it separate from your card.
