Yes, you can use your credit card abroad, but it will cost you more than using it at home

Most credit cards work in other countries. Your card will be accepted at stores, restaurants, and ATMs in nearly every developed nation and many developing ones. The catch is that your bank charges you fees for the privilege, and the exchange rate you get is rarely the best one available. Understanding these costs before you leave means you can choose a card that minimizes them — or decide whether a different payment method makes more sense for your trip.

The two main costs are the foreign transaction fee (a percentage of what you spend) and the exchange rate markup (the difference between what your bank pays for the currency and what it charges you). Some cards charge one, some charge both, and a few charge neither. A third cost — ATM fees — applies only if you withdraw cash.

Key Takeaways

  • Most credit cards charge a foreign transaction fee of 1% to 3% on purchases made outside the United States, plus a markup on the exchange rate.
  • Some cards marketed to travelers charge no foreign transaction fee, though you should confirm this before you travel.
  • Your card will work at most merchants and ATMs abroad, but some countries and smaller towns rely more on cash or local payment apps.
  • Notifying your bank before you leave prevents your card from being blocked as fraud, though many cards now allow you to set travel alerts through their app.
  • Using a credit card abroad is usually safer than carrying large amounts of cash, because you can dispute fraudulent charges and your liability is capped.

Foreign transaction fees and exchange rate markups

When you swipe your card in another country, two separate charges happen. First, your transaction is converted from the local currency to US dollars using an exchange rate. Your bank does not use the real market rate — it adds a markup, usually 1% to 2%. Then, on top of that, many cards charge a foreign transaction fee, typically 1% to 3% of the purchase amount.

A $100 purchase in euros might look like this: the merchant charges you 92 euros (the real amount). Your bank converts that at the real rate of 1.08 dollars per euro, which equals $99.36. Then it adds a 2% exchange markup ($1.99) and a 2% foreign transaction fee ($2.00), and you are charged $103.35. You paid $3.35 extra for the privilege of using your card.

The fee structure varies by card. Some cards charge no foreign transaction fee but still apply the exchange markup. Some charge both. A few premium cards and cards designed for travelers charge neither. Check your card's terms before you leave — your bank's website or app will list the foreign transaction fee under "Fees" or "International Use."

Cards that charge no foreign transaction fee

If you travel regularly or are planning a longer trip, a card with no foreign transaction fee can save you real money. These cards exist, though they are not the default. Some are premium cards that charge an annual fee but waive the foreign transaction fee. Others are designed specifically for travelers and charge no annual fee at all.

The tradeoff is usually one of these: the card charges an annual fee (often $95 to $450), it offers a lower cash-back rate on everyday purchases, or it requires a higher credit score to be approved. A card that charges $95 per year but saves you 2% on every purchase abroad makes sense if you spend more than $4,750 internationally per year. For a one-week vacation, it probably does not.

If you already have a card and want to know whether it charges a foreign transaction fee, log into your online account or call the number on the back of your card. Ask directly: "Does this card charge a foreign transaction fee?" The answer will be yes or no.

How to use an ATM abroad without overpaying

Withdrawing cash from an ATM in another country triggers three separate fees: your bank's ATM fee (if any), the foreign bank's ATM fee (usually $2 to $5), and the exchange markup. Some banks also charge a "cash advance fee" if they treat ATM withdrawals as advances rather than regular transactions.

To minimize the damage, withdraw larger amounts less often. A single $200 withdrawal costs less per dollar than four $50 withdrawals, because you pay the ATM fees only once. Before you leave, ask your bank whether it has a partnership with banks in the country you are visiting — some do, and partner ATMs waive their fees.

Using a debit card at an ATM abroad usually costs less than using a credit card, because debit transactions are not treated as cash advances and do not trigger the same fees. However, debit cards offer less fraud protection than credit cards. If your debit card number is stolen, the money is gone from your account immediately, and you have to fight to get it back. With a credit card, the charge is disputed and you are not out the money while the dispute is resolved.

Notifying your bank before you travel

Call your bank or use its app to tell them you will be traveling and where. This prevents your card from being blocked when it detects unusual activity — a purchase in Madrid followed by a purchase in Barcelona a few hours later looks like fraud to an automated system.

Most banks now let you set a travel alert through their mobile app without calling. Open the app, look for "Travel" or "Notifications," and enter your destination and travel dates. If your card is blocked anyway, you will need to call the number on the back of your card to unblock it, which is difficult when you are in another country with limited phone service.

Setting a travel alert does not change your fees or your liability. It simply tells the bank's fraud detection system to expect activity in that location.

What happens if your card is declined or lost abroad

If your card is declined, it is usually because your bank blocked it as fraud (which a travel alert should prevent) or because the merchant's system does not accept your card type. Visa and Mastercard are accepted almost everywhere, but American Express and Discover are less widely accepted outside the United States, particularly in smaller towns and developing countries.

If your card is lost or stolen, call your bank immediately using the number on your statement or the bank's website — do not rely on the number on the back of the card, because a thief could have altered it. Your liability for fraudulent charges is capped at $50 under US law, and most banks cap it at $0 if you report the loss quickly. The bank will cancel the card and can arrange for a replacement to be sent to your hotel or home address.

Carrying a backup card from a different bank is smart. If one card is declined or lost, you have another option. Keep the two cards in different places — one in your wallet, one in your hotel safe.

Countries and situations where credit cards do not work well

Credit cards work in most developed countries and major cities worldwide. They work poorly in some places: rural areas in developing countries, very small towns, street markets, and some countries with strict currency controls. Vietnam, Thailand, and parts of Central America still rely heavily on cash. Some countries like Cuba have limited acceptance of US cards at all.

Before you travel, research whether credit cards are widely used where you are going. Check travel forums or your hotel's website. If cash is the norm, plan to withdraw money from an ATM when you arrive rather than carrying large amounts from home. If your destination has limited ATM access, withdraw cash in a major city before heading to smaller towns.

Some merchants abroad, particularly small ones, charge a fee for credit card use or offer a discount for cash. This is legal in most countries. You can negotiate or choose to pay cash, but you cannot dispute the fee after the fact.

Credit card fraud protection abroad

Using a credit card abroad is safer than carrying cash. If someone steals your card number, you can dispute the charge and your liability is capped at $50 (and usually $0 if you report it quickly). If someone steals $500 in cash, it is gone.

Credit card companies monitor for fraud patterns, and your travel alert helps them distinguish legitimate purchases from theft. If a charge looks suspicious, the company will contact you — usually by phone or email — before processing it. Respond quickly so your legitimate purchases are not delayed.

Keep your receipts and check your statement when you return home. Disputes must usually be reported within 60 days of the charge appearing on your statement. If you notice a fraudulent charge, contact your bank immediately with the receipt and the merchant's name.

Frequently Asked Questions

Will my credit card work everywhere I travel?

Visa and Mastercard work in most countries and cities, but acceptance drops in rural areas and developing nations. American Express and Discover are less widely accepted outside the US. Before you travel, research your specific destination — travel forums and your hotel's website can tell you whether credit cards are common there.

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

Yes, but it is expensive. You will pay your bank's ATM fee, the foreign bank's ATM fee (usually $2 to $5), an exchange markup, and sometimes a cash advance fee. Using a debit card at an ATM costs less, but offers less fraud protection. Withdraw larger amounts less often to minimize fees.

What should I do if my card is declined while I am traveling?

First, check whether you set a travel alert — if not, the decline might be fraud prevention. If you did set an alert, the merchant's system may not accept your card type (American Express and Discover are less widely accepted). Try a different merchant or payment method. If you have a backup card, use that instead.

Do I need to tell my bank I am traveling?

Yes. Without notice, your bank may block your card as fraud when it detects activity in another country. Most banks let you set a travel alert through their app in seconds. If your card is blocked anyway, you will need to call the bank to unblock it, which is difficult abroad.

What is the difference between a foreign transaction fee and an exchange rate markup?

The exchange rate markup is the difference between what your bank pays for the currency and what it charges you — usually 1% to 2%. The foreign transaction fee is an additional percentage charge (typically 1% to 3%) that some cards add on top of that. Some cards charge both, some charge one, and some charge neither.
