What happens to your credit card when you use it overseas

When you swipe a credit card in another country, three separate fees can hit your bill: a foreign transaction fee (usually 1–3% of the purchase), a currency conversion markup (added by your card network or bank), and sometimes a cash advance fee if you withdraw money from an ATM. Most banks charge all three. The card issuer converts your purchase to dollars at a rate they set, not the real market rate, and pockets the difference. You do not see these fees itemized on your receipt — they appear on your statement days later.

The cost compounds fast. A €100 dinner in Paris might cost you $108 at the real exchange rate, but $112 or more after your bank's markup and fees. Over a two-week trip, this can add $200 to $400 to your total spending. The good news is that some cards charge no foreign transaction fees at all, and knowing which ones exist before you leave means you can avoid most of this cost.

Key Takeaways

  • Cards with no foreign transaction fees exist and are offered by many major banks and credit unions; check your card's terms before traveling or request a different card from your issuer.
  • Currency conversion markup is separate from transaction fees and is set by your bank or card network; you cannot avoid it entirely, but some cards apply smaller markups than others.
  • Using ATMs in the destination country usually costs less per dollar than using currency exchange booths or paying in dollars at a merchant.
  • Notify your bank of your travel dates so they do not block your card as fraud, but this does not change fees — it only prevents your card from being declined.
  • Carrying a second card from a different issuer protects you if one card is lost, declined, or stops working.

Finding a card with no foreign transaction fees

Before you travel, call your current card issuer and ask whether your card charges a foreign transaction fee. If it does, ask whether they offer a different card in your name that does not. Many banks have a travel rewards card or a basic card with no foreign fees. Switching to that card before you leave takes one phone call and a few days for the new card to arrive.

If your current issuer does not offer a no-fee option, you can open a new card with a bank or credit union that does. Major issuers like Chase, Bank of America, and Citi offer cards with zero foreign transaction fees. Credit unions often have them too. You do not need to close your old card — having two cards is actually safer when traveling, because if one is lost or declined, you have a backup.

Read the fine print on any card you are considering. The term "no foreign transaction fees" means the card issuer does not add their own fee, but the card network (Visa, Mastercard, American Express) still applies a currency conversion markup. That markup is unavoidable, but it is usually smaller than the combined fee-plus-markup you pay with a card that charges transaction fees.

Understanding currency conversion and network markups

Your card network — Visa, Mastercard, or American Express — sets the exchange rate they use to convert your purchase to dollars. This rate is almost always higher than the real market rate, and the difference is their profit. Visa's markup is typically 1%, Mastercard's is similar, and American Express is often higher. You cannot negotiate this or avoid it; it is built into how the system works.

Some banks add their own markup on top of the network's markup. So you might see a 1% network conversion fee plus a 1% bank fee, totaling 2% before you even count a foreign transaction fee. This is why reading your card's terms matters — you want to know the total cost, not just whether there is a transaction fee.

The real exchange rate changes every day and is published by financial data services. You can check what the true rate is on XE.com or OANDA before you travel, so you know what a fair conversion looks like. When you see your statement, you can calculate whether the rate your bank used was reasonable.

Using ATMs and cash strategically

Withdrawing cash from an ATM in the destination country usually costs less than paying with a card at every merchant or using a currency exchange booth. Most ATM fees are a flat $2 to $5 per withdrawal, regardless of the amount. If you withdraw €200 at once, you pay one fee. If you make four €50 withdrawals, you pay four fees. Withdraw larger amounts less often to minimize the number of transactions.

Before you leave, ask your bank what their ATM fee is for out-of-network withdrawals abroad. Some banks waive this fee for customers who travel frequently or have certain account types. Also ask whether the ATM's local bank will charge you an additional fee — many do, and you will see it on the ATM screen before you confirm the withdrawal. You can decline and try a different ATM if the fee is high.

Use your card to pay for larger purchases (hotels, restaurants, flights) and cash for small transactions (street food, tips, public transit). This spreads your costs across different fee structures and gives you a backup if your card stops working.

Notifying your bank and protecting your card

Contact your bank or card issuer before you travel and tell them your destination and the dates you will be there. This prevents them from blocking your card as a fraud risk when they see charges from another country. You do not need to ask permission — you are just informing them. This step does not change any fees; it only keeps your card from being declined.

Some banks let you set travel notifications online through their app or website. Others require a phone call. Check your card's website or the back of your card for the customer service number and the process they use.

While you are traveling, keep your card in a safe place and do not let merchants take it out of your sight. In some countries, card skimming is common, and a dishonest employee can copy your card number. Use ATMs in well-lit, secure locations like bank lobbies or shopping centers rather than street-side machines.

Comparing cards and planning your strategy

If you travel regularly, it is worth comparing cards before you go. A card with no foreign transaction fees, a low network markup, and good fraud protection will save you money over time. Some travel rewards cards offer bonus points on international purchases, which can offset some costs if you redeem the points for future travel.

For a single trip, the math is simpler: find a card with no foreign transaction fees, use it for large purchases, withdraw cash for small ones, and you will pay only the network's currency conversion markup — usually 1–2% total. That is far less than the 3–5% you would pay with a card that charges transaction fees.

Write down your card issuer's customer service number and keep it separate from your card. If your card is lost or stolen, you can call from anywhere and have it replaced or blocked. Many issuers can send a replacement card to a hotel or have you pick one up at a branch abroad.

What to do if your card is declined or stops working

If your card is declined, do not panic. Call your bank's customer service line (the number on the back of your card or in your records) and ask why. It might be a fraud hold that you can clear over the phone, a technical glitch, or a problem with the merchant's terminal. Your bank can often unblock it immediately.

This is why carrying a second card is important. If one card fails, you have another way to pay while you figure out what went wrong. If both cards fail, you can ask your bank to wire money to a local bank branch or have someone send you money through a service like Western Union.

After you return home, review your statement carefully. Look for charges you do not recognize and report them to your bank within 60 days. Most banks have zero-liability policies for fraudulent charges, but you have to report them promptly.

Frequently Asked Questions

Should I exchange money before I leave or wait until I arrive?

Wait until you arrive and use an ATM. Airport currency exchange booths charge high markups — often 5–10% — because they know travelers are desperate. An ATM in the destination country charges a flat fee that is usually much lower. If you must exchange money before you leave, do it at your bank, not at an airport booth.

Is it better to pay in dollars or the local currency when a merchant offers both?

Always choose the local currency. When a merchant offers to charge you in dollars (called dynamic currency conversion), they set the exchange rate themselves and it is almost always worse than what your card network would use. You will pay 3–5% more by accepting the dollar price.

Do I need a special travel card or can I use my regular card?

Your regular card works fine if it has no foreign transaction fees. You do not need a special travel card. If your regular card charges foreign transaction fees, switching to a different card from the same bank or opening a new card elsewhere is cheaper than paying fees on every purchase.

What if I lose my card while traveling?

Call your card issuer immediately using the number on your records or from your bank's website. They will cancel the card and can often send a replacement to your hotel or a local branch. This is why carrying a second card is important — you have a backup while the replacement arrives.

Are prepaid travel cards better than credit cards?

Prepaid travel cards can work, but they often charge more fees than a credit card with no foreign transaction fees. Compare the total cost: prepaid cards may charge loading fees, ATM fees, and currency conversion markups. A regular credit card with no foreign transaction fees is usually cheaper.
