How to Avoid Foreign Transaction Fees and Bad Exchange Rates Abroad
Where the hidden costs of paying abroad come from, and a simple strategy for cards, cash and ATMs that keeps more of your travel budget in your pocket.
The short answer: to keep payment costs low abroad, use a credit or debit card that charges no foreign transaction fee, always choose to pay in the local currency when a card machine or ATM offers you a choice, withdraw cash from bank ATMs in larger, less frequent amounts using a card that refunds or does not charge ATM fees, and avoid airport and street exchange kiosks. These four habits remove most of the extra costs travelers pay, which can otherwise add several percent to everything you spend.
This guide explains each type of fee, how exchange rates work, and how to build a simple payment plan for any trip.
The four costs of paying abroad
When you spend money in another currency, you can pay in four different ways, often without noticing:
| Cost | What it is | Who charges it | How to avoid it |
|---|---|---|---|
| Foreign transaction fee | A percentage added to purchases in a foreign currency | Your card issuer | Use a card with no foreign transaction fee |
| Dynamic currency conversion markup | A worse exchange rate when you pay in your home currency abroad | The merchant or ATM operator | Always choose local currency |
| ATM fees | A flat or percentage fee for cash withdrawals | Your bank, the ATM owner, or both | Use fee free or fee refunding cards, withdraw less often |
| Exchange rate margin | The gap between the market rate and the rate you get | Exchange offices, banks, card networks | Use card network rates, avoid kiosks |
Each is explained in detail below.
Foreign transaction fees
A foreign transaction fee is a charge your card issuer adds when you make a purchase in a foreign currency, or sometimes when you buy from a merchant based abroad even in your home currency. In the United States, the Consumer Financial Protection Bureau describes these fees as commonly around 3 percent of the purchase on cards that charge them.
Three percent sounds small, but on a trip where you spend the equivalent of 3,000 US dollars on your card, it adds about 90 dollars for nothing.
How to avoid it:
- Check your card's terms. Look for "foreign transaction fee" in the fee table or cardholder agreement.
- Get a no fee card before you travel if your current cards charge one. Many travel credit cards and some debit cards and digital banks charge no foreign transaction fee.
- Carry two cards from different networks if possible (for example one Visa and one Mastercard), in case one is not accepted or is blocked.
Dynamic currency conversion: the most avoidable cost
Dynamic currency conversion (DCC) is when a card machine, online checkout or ATM abroad offers to charge you in your home currency instead of the local currency. It sounds convenient because you see a familiar amount. But the exchange rate used is set by the merchant's provider and usually includes a markup that is worse than the rate your own card network would use.
You might see a screen like this:
- "Pay 100.00 EUR" or "Pay 112.50 USD"
The second option often includes a markup of several percent, on top of any fee your card charges.
How to avoid it:
- Always choose the local currency on card machines, ATMs and online checkouts.
- If a cashier asks, say you want to pay in the local currency.
- Check the receipt. If you were charged in your home currency without being asked, you can ask for the transaction to be refunded and run again in local currency.
In the European Union, rules require that the full cost of currency conversion is disclosed to you before you pay, so read the screen carefully before you press accept.
ATM fees and how to reduce them
Cash withdrawals abroad can involve several layers of fees:
- Your bank's foreign ATM fee: a flat fee, a percentage, or both.
- The ATM operator's fee: some ATMs abroad add their own charge, which must usually be shown on screen before you confirm.
- The foreign transaction fee, if your debit card charges one.
- DCC if you accept the ATM's offer to convert the amount for you.
Ways to reduce them:
- Use a debit card designed for travel, which charges no foreign ATM fees or refunds ATM operator fees.
- Use ATMs belonging to major banks, located inside or next to bank branches. Independent ATMs in tourist areas often charge higher fees.
- Withdraw larger amounts less often, if you can carry cash safely, because flat fees cost less per unit of currency on larger withdrawals.
- Decline the conversion offer and choose to be charged in the local currency.
- Never use a credit card for ATM cash unless it is an emergency. Credit card cash advances usually carry an immediate fee and interest from the day of withdrawal.
Exchange rates and exchange offices
The mid market rate is the midpoint between the buying and selling prices of a currency on global markets. It is the rate you see on financial news sites. Almost nobody gets exactly this rate, but card networks such as Visa and Mastercard use rates close to it, which is why card payments in local currency are usually the cheapest way to pay.
Exchange offices make money from the gap between the rate they offer and the mid market rate, plus any commission. Airport, hotel and street exchange kiosks often offer the worst rates because travelers have few alternatives.
How to compare an exchange offer:
- Find the current mid market rate on a reliable financial site.
- Ask how much local currency you will receive for a fixed amount of your currency, after all fees and commissions.
- Compare that with the mid market amount. The difference is the real cost.
"Zero commission" signs do not mean the exchange is free. The cost is usually built into a worse rate.
How much cash should you carry?
Cash needs vary a great deal by destination. In some countries, cards are accepted almost everywhere, including for small purchases and public transport. In others, small shops, markets, taxis and rural areas may be cash only.
A practical approach:
- Research card acceptance at your destination before you go, using recent traveler reports and official tourism sites.
- Arrive with a small amount of local currency for your first transport and a meal, or withdraw it from a bank ATM at the airport.
- Keep cash split across two places, such as your wallet and a separate secure pouch.
- Keep small notes for tips, markets and transport.
Paying in specific situations
Some everyday travel situations have their own payment traps. Here is how to handle the most common ones.
Hotel check in and deposits
Hotels often place a hold on your card at check in to cover incidentals. A hold is not a charge, but it reduces your available credit or, on a debit card, can lock up your actual money for several days after you check out. Use a credit card for hotel deposits where possible, and ask how much will be held and when it will be released.
Car rental
Car rental companies usually require a credit card in the main driver's name, and they place a large hold for the security deposit. Many will not accept debit cards for the deposit. At the counter, you may also be offered DCC on the final bill, so ask for the charge in local currency. Check whether your credit card includes rental car insurance before buying extra cover, and read the exclusions carefully.
Restaurants and tipping
In many countries, a waiter brings a portable card machine to the table. This is where DCC offers are most common, so read the screen before you confirm. Tipping customs vary widely. In some places, a service charge is already on the bill, while in others tips are expected in cash. Check the custom for your destination; our guide to cultural etiquette abroad covers how to research local norms.
Public transport
Many cities now accept contactless bank cards and mobile wallets directly at transit gates. This is often the cheapest and easiest way to pay, because some systems cap daily or weekly fares automatically. If you use a card with a foreign transaction fee, each small tap adds a fee, so use a no fee card for transit.
Tax free shopping refunds
Some countries let visitors reclaim sales tax or value added tax on goods they take home. Refunds are usually processed at the airport or border, and refund services may take a commission. When offered a refund in your home currency, compare it with a refund in the local currency to the card, which usually avoids a conversion markup.
Paying for activities and tours online
When booking tours or tickets from a foreign website, the price may be shown in your home currency as a convenience. Where you can, switch the website's currency to the local one and pay with a no foreign transaction fee card, which avoids a conversion by the booking site.
Protecting your cards and money
Fees are only one part of money safety. Protect yourself against loss and fraud:
- Turn on transaction alerts in your banking app so you see every charge immediately.
- Know how to freeze your card in the app, and save your bank's international phone number.
- Carry a backup card separately from your main one.
- Cover the keypad when entering your PIN, and be wary of anyone offering help at an ATM. Our guide to common travel scams describes ATM and card tricks.
- Use contactless or mobile payments where available, which reduce card handling.
Building a payment plan for your trip
Use this plan for any international trip:
| Purpose | Best option | Backup |
|---|---|---|
| Everyday purchases | No foreign transaction fee credit card, in local currency | Second card on a different network |
| Cash | Fee free or fee refunding debit card at a bank ATM | Small amount of currency brought from home |
| Hotel and car rental deposits | Credit card (deposits are holds, not charges) | Second credit card |
| Online bookings in foreign currency | No foreign transaction fee card, in local currency | Pay in your currency only if the merchant is in your country |
| Emergencies | Backup card kept separately | Emergency cash in a separate place |
Before you leave, check each card's foreign transaction fee, ATM fees and daily withdrawal limit, and confirm your bank will not block foreign transactions. Add these tasks to your preparation using our international travel checklist.
A worked example of the savings
Imagine a two week trip where you spend the equivalent of 2,000 US dollars on a card and withdraw the equivalent of 600 dollars in cash in three withdrawals.
| Scenario | Card purchases | Cash withdrawals | Approximate extra cost |
|---|---|---|---|
| Card with 3% foreign transaction fee, accepting DCC sometimes, using independent ATMs with fees | 3% fee plus DCC markups on some purchases | Bank fee plus ATM operator fee per withdrawal, plus 3% | Often well over 100 dollars |
| No foreign fee card, always local currency, fee refunding debit card | No fee, network exchange rate | No fees or fees refunded | Close to zero beyond the network rate |
The exact numbers depend on your cards and destination, but the pattern is consistent: the strategy above removes almost all avoidable costs.
Frequently asked questions
Should I pay in local currency or my home currency abroad?
Pay in local currency. Choosing your home currency triggers dynamic currency conversion, which usually uses a worse exchange rate than your card network.
Is it cheaper to exchange money before I travel?
Usually not. Exchanging at home through a bank or exchange office often gives a worse rate than withdrawing from a bank ATM abroad with a low fee card. Bring only a small amount for arrival if you want peace of mind.
Do I need to tell my bank I am traveling?
Many banks now detect travel automatically, but some still block unexpected foreign transactions. Check your banking app for a travel notice option, and make sure your contact details are up to date so the bank can reach you.
Are prepaid travel cards worth it?
They can help with budgeting and limit fraud exposure, but some charge load fees, inactivity fees or poor exchange rates. Compare their total costs with a no fee debit or credit card before buying.
Why was I charged a foreign transaction fee on an online purchase in my own currency?
Some issuers charge the fee when the merchant processes the payment outside your country, even if the price is in your currency. Check where the merchant is based, or use a no foreign transaction fee card for international websites.
