Using Your Bank Card Abroad: Fees and What to Avoid
Small, avoidable mistakes at the till or the cash machine can cost more over a trip than most people realise.

Card payments abroad are generally safe and convenient, but the fee structures behind them are not always obvious, and a few common habits quietly cost travellers money on almost every trip. None of the amounts below are fixed figures, since every bank and card sets its own terms, but the shape of the costs, and the specific mistakes to avoid, are consistent enough to be worth understanding before you travel.
Foreign transaction fees
Many debit and credit cards charge a foreign transaction fee, a percentage added to purchases made in a currency other than your card's home currency. This fee is set by your card issuer, not by the shop or the country you're in, and it applies whether you're paying by chip, contactless or online in a foreign currency. Some cards, often ones specifically marketed for travel, waive this fee entirely, while ordinary current account debit cards commonly include one.
The only way to know your card's fee, if any, is to check your card issuer's own fee schedule, usually available in the terms and conditions or the app, before you travel. If you travel often, it can be worth comparing your existing cards' terms, or looking at whether your bank offers a travel-friendly card or account, rather than assuming your everyday card is the cheapest option abroad.
Dynamic currency conversion: always decline it
At many card terminals and ATMs abroad, you may be asked whether you want to pay in your home currency or the local currency, a choice known as dynamic currency conversion. This sounds like a convenience, letting you see the cost in familiar terms, but the exchange rate applied is set by the merchant's payment provider or the ATM operator, and it is typically less favourable than the rate your own card issuer would apply.
The reliable rule is to always choose to pay in the local currency, not your home currency, whenever this option appears, whether at a shop terminal or a cash machine. This ensures your own card network handles the currency conversion at its own rate, which is virtually always the better deal. This single habit is one of the most effective ways to avoid unnecessary cost on card payments abroad.
ATM fees and choosing where to withdraw
Cash machines abroad can charge their own withdrawal fee, separate from anything your own bank charges, and this fee is set by whichever bank or operator owns that specific machine. Fees can vary considerably between a machine inside a bank branch and one in a tourist area or transport hub, so where possible, withdrawing from a machine belonging to a recognised local bank, rather than an independent or branded tourist-area machine, is generally the more cost-effective choice, though this varies by country and cannot be stated as a universal rule.
It is also worth checking your own bank's policy on foreign ATM withdrawals, since some charge a flat fee or percentage on top of any fee charged by the machine itself, while others waive this for certain account types. Withdrawing larger amounts less often, rather than making several small withdrawals, can reduce the impact of any flat per-withdrawal fee, though this needs balancing against the risk of carrying more cash.
Credit vs debit, and carrying some cash
Credit cards often carry different consumer protections from debit cards for disputed transactions or fraud, and many people prefer using a credit card for larger purchases abroad for this reason, alongside the potential rewards some offer. That said, credit cards can also carry cash advance fees and different interest terms if used to withdraw cash from an ATM, so check your specific card's terms before using it that way.
Even in destinations where cards are widely accepted, carrying a modest amount of local cash remains sensible for smaller vendors, markets, some public transport systems, or situations where card machines are down. How much cash is sensible varies by destination and personal comfort, but relying entirely on cards with no cash backup can leave you stuck in genuinely common situations.
Travel notifications and basic card hygiene
Many banks used to require a travel notification before use abroad to avoid transactions being flagged as suspicious; this is less universally necessary now with better fraud detection, but it is still worth checking your specific bank's current guidance, since some still recommend or require it, particularly for less common destinations. It is a quick check that can prevent a card being blocked mid-trip.
Basic card safety habits are worth keeping up while travelling: cover the keypad when entering a PIN, be wary of ATMs that look tampered with or are in isolated locations, and check your account activity periodically during a trip rather than only after returning home, so any unauthorised transaction is caught and reported quickly. Keeping a secondary card, stored separately from your primary one, is a sensible backup in case a card is lost, blocked or retained by a machine.
