Paying for a €5 coffee abroad can cost more than €5 once your bank gets involved. Foreign transaction fees, exchange-rate mark-ups, ATM charges and credit-card interest can quietly increase the cost of a holiday, particularly if you use the wrong card repeatedly throughout your trip.
The tricky part is that neither debit cards nor credit cards are automatically cheaper abroad. A fee-free travel debit card can cost less than an expensive credit card, while a specialist travel credit card can beat a standard debit card that adds a foreign transaction fee to every purchase. How you use the card matters just as much as which type of card you carry.
In this Saving Guide Hub travel money guide, we compare debit cards vs credit cards abroad, explain the charges to look for and show you how to reduce unnecessary card fees while travelling.
For everyday purchases abroad, the cheapest option is usually a debit or credit card specifically designed for fee-free overseas spending rather than simply choosing one type of card over the other. Specialist travel cards can offer competitive Visa or Mastercard exchange rates without adding the foreign transaction fees charged by many standard cards.
Credit cards can have an additional advantage when you make qualifying larger purchases because Section 75 of the Consumer Credit Act can provide legal protection on purchases costing more than £100 and up to £30,000. Debit cards do not receive Section 75 protection, although eligible purchases may be covered through the chargeback scheme.
Cash withdrawals change the comparison. Using a credit card at an overseas ATM can be expensive because some providers charge cash-withdrawal fees and interest may begin immediately. A debit card with fee-free international cash withdrawals may therefore be more suitable for accessing cash, subject to its limits and any fee charged separately by the overseas ATM operator.
| Situation | Debit Card | Credit Card |
|---|---|---|
| Everyday overseas purchases | Can be cheap with a fee-free travel card | Can be cheap with a fee-free travel card |
| Foreign transaction fees | Depends on account | Depends on card |
| Cash withdrawals | Often better with the right travel debit card | Can attract fees and immediate interest |
| Section 75 protection | No | Yes, on qualifying purchases |
| Chargeback | Usually available | Usually available |
| Risk of borrowing | Spending comes from your bank balance | Spending creates debt until repaid |
| Best for | Daily spending and potentially cash | Purchases where protection matters |
The important point is that the words “debit” and “credit” alone do not tell you which card will cost less. You need to check the actual overseas fee structure.
When you make a purchase in another currency, the amount has to be converted into pounds before it appears on your account or credit-card statement. Your card network, usually Visa or Mastercard, provides an exchange rate for that conversion, and your bank or card issuer may then apply additional charges.
MoneyHelper says banks commonly use Visa or Mastercard exchange rates for debit-card transactions abroad, but the bank may add a currency-exchange fee that is often around 3% of the transaction amount. Depending on the account and circumstances, additional spending or cash-withdrawal charges may also apply.
This is why two travellers buying exactly the same €100 meal can ultimately pay different amounts in pounds. One may use a specialist card with no additional foreign transaction fee, while the other may use a standard card that adds roughly 3% on top of the converted amount.
Before travelling, therefore, check the overseas spending section of your card’s current fee schedule rather than assuming your normal UK banking terms apply internationally.
A foreign transaction fee, sometimes called a non-sterling transaction fee, is an additional charge that some card providers apply when you spend in a currency other than pounds sterling. The fee is usually calculated as a percentage of the transaction.
If your card charged 2.99%, for example, £1,000 of qualifying overseas purchases would create approximately £29.90 in additional transaction fees. That would be on top of whatever sterling amount results from the currency conversion itself.
The difference becomes more noticeable on expensive holidays. Hotels, restaurants, attraction tickets, shopping and transport can collectively create dozens of card transactions, so a percentage fee applied repeatedly can become a meaningful part of your travel budget.
This is why checking your card before travelling is one of the simplest ways to save money on holiday. You do not necessarily need to stop using cards abroad; you need to understand what your particular card charges.
Debit cards can be extremely cheap for overseas spending when they are linked to an account that does not add foreign transaction fees. They can also make budgeting easier because purchases normally come directly from money you already hold rather than creating a balance that needs to be repaid later.
However, a standard UK debit card can be expensive overseas if the provider adds a percentage foreign-exchange fee or separate transaction charges. Using such a card repeatedly for small purchases can mean paying additional fees throughout the holiday.
A debit card is therefore not automatically a cheap travel card simply because you already use it every day in the UK. Before departure, check the foreign purchase fee, overseas ATM fee and any limits that apply to fee-free international use.
For travellers trying to maintain a strict monthly budget, debit cards can nevertheless have an important psychological advantage. Because the money normally leaves your available bank balance quickly, it can be easier to see how much of your holiday spending money remains.
A specialist travel credit card can also be one of the cheapest ways to pay abroad when it does not charge a foreign transaction fee on purchases. Used correctly, it can combine competitive currency conversion with stronger purchase protection than a debit card.
The important phrase is “used correctly”. Credit-card spending is borrowing. If you do not repay the balance according to the card’s terms, interest can easily outweigh the money you saved on foreign transaction fees.
A card charging no overseas purchase fee can therefore become expensive if you return home with a balance that remains unpaid for months. When comparing cards for travel, look at both the foreign-spending fee and the card’s normal borrowing costs.
If you can afford the holiday from existing savings, a credit card can still be used for the transaction and then repaid in full. However, using credit to fund a trip you cannot otherwise afford creates a completely different financial calculation.
One of the strongest arguments for using a credit card abroad is Section 75 protection. Under the Consumer Credit Act, qualifying purchases costing more than £100 and up to £30,000 can make the credit-card provider jointly responsible with the seller if there is a breach of contract or misrepresentation.
Importantly, this protection can apply to purchases made overseas as well as in the UK. That can make a credit card particularly useful for qualifying hotel bookings, flights and other significant travel purchases, although the exact payment structure matters and some transactions involving intermediaries can complicate Section 75 eligibility.
You do not necessarily have to pay the entire purchase price on the credit card for Section 75 to potentially apply. If a qualifying item costs more than £100 and up to £30,000, paying only part of it directly on the credit card can still potentially bring the full purchase within Section 75 protection, subject to the rules.
Debit cards do not receive Section 75 protection. Instead, cardholders may be able to use chargeback when something goes wrong with a purchase. Chargeback can be valuable, but unlike Section 75 it is a card-scheme process rather than the same statutory protection.
Chargeback allows a card provider to attempt to reverse a transaction in certain circumstances, such as when goods do not arrive or a company refuses an appropriate refund. MoneyHelper states that chargeback can apply to debit, credit and prepaid cards, with claims generally needing to be started within 120 days of the relevant purchase or event date.
Section 75 provides a different type of protection because it is established in UK law. For qualifying credit-card purchases, the card issuer can share responsibility with the supplier when the required conditions are satisfied.
This means a credit card can have an advantage when booking expensive travel services. However, consumers should not assume every transaction automatically qualifies. Paying through certain third-party payment processors or intermediaries can sometimes affect the necessary relationship between the cardholder, card issuer and supplier.
For expensive holiday purchases, it is therefore worth considering both the cost of the card and the protection attached to the payment method.
Cash withdrawals are where the comparison changes significantly. Credit cards are generally not the first choice for withdrawing cash because many providers charge a cash-withdrawal fee, and cash transactions can begin attracting interest immediately rather than receiving the interest-free period that may apply to normal purchases.
MoneySavingExpert’s current travel-card guidance also warns that overseas cash machines can impose their own charges independently of your UK card provider. This means even a card advertised as fee-free for overseas withdrawals cannot necessarily prevent the local ATM owner from charging you.
A suitable travel debit card can therefore be a more practical option for cash. However, you still need to check whether the account has fee-free withdrawal limits, whether a fair-use threshold applies and whether the overseas ATM adds its own charge.
Making many small ATM withdrawals can also expose you repeatedly to fixed ATM fees. If a trusted ATM charges a fixed fee, fewer sensible withdrawals may cost less than repeatedly withdrawing tiny amounts, provided you can store the cash securely.
Credit-card cash withdrawals are different from normal card purchases. Depending on the provider, you may pay a withdrawal fee and begin paying interest from the date of the transaction. That can happen even if you normally clear your credit-card statement in full.
For example, withdrawing the equivalent of £200 from an overseas ATM could involve a card-provider cash fee, a local ATM fee and interest. Currency conversion may create another cost if the card also charges for foreign transactions.
There may also be broader consequences from using credit cards for cash withdrawals, so it is generally sensible to check the card’s terms before treating a credit card as your primary source of holiday cash.
A credit card that is excellent for purchases is therefore not automatically excellent for ATM withdrawals. Saving Guide Hub recommends comparing these two activities separately.
When a foreign card terminal or ATM recognises a UK card, it may offer you a choice between paying in pounds or the local currency. Seeing the price in pounds can feel reassuring because you immediately know the sterling amount, but it may not provide the better exchange rate.
This process is commonly known as dynamic currency conversion. When you choose pounds, the conversion can be performed using the merchant or ATM provider’s rate rather than allowing your card network and provider to handle the currency conversion under your normal card terms.
For many travellers using a competitive travel card, choosing the local currency is generally the option to look for. That means euros in eurozone countries, US dollars in the United States and the relevant local currency elsewhere.
Always read the terminal carefully before confirming the payment. A seemingly harmless currency choice can affect the final sterling cost of the transaction.
Imagine two UK travellers each make purchases equivalent to £1,000 during a holiday. Traveller A uses a standard card that adds a 2.99% foreign transaction fee, while Traveller B uses an appropriate travel card that does not add a foreign transaction fee to eligible purchases.
Ignoring other differences in exchange rates or charges, Traveller A would pay approximately £29.90 in additional foreign transaction fees. Traveller B would avoid that particular charge.
Now imagine spending £3,000 on hotels, restaurants, transport and shopping during a longer trip. A 2.99% charge would equal approximately £89.70.
The lesson is not that every fee-free card will always save exactly that amount. Exchange rates, ATM fees, interest and card-specific conditions still matter. The example simply demonstrates why a percentage that looks small can become significant when applied across an entire holiday.
Hotels can create situations where a credit card is particularly convenient. Some hotels take a pre-authorisation or temporary security hold when you check in, especially for incidentals such as room service or damage deposits.
If the hold is placed on your debit card, part of your actual bank balance can temporarily become unavailable. With a credit card, the hold normally reduces your available credit instead of tying up money in your current account.
A credit card may also offer Section 75 protection for qualifying hotel purchases. That can add another reason to consider credit for a significant direct hotel booking, provided the transaction meets the legal requirements and you manage the credit-card balance responsibly.
However, always check the hotel’s payment and deposit policy before travelling. A traveller relying exclusively on a debit card may want to know in advance how large a security hold could be.
For qualifying flight purchases costing more than £100 and up to £30,000, paying directly with a credit card can potentially provide Section 75 protection. This can be valuable if the airline fails to provide the service or another covered problem occurs.
However, the structure of the booking matters. MoneyHelper notes that transactions involving certain third parties can affect whether Section 75 applies, because the necessary direct relationship can be broken.
A debit card may still provide access to chargeback if something goes wrong, but it does not provide the same statutory Section 75 protection.
When booking an expensive trip, payment protection should therefore be considered alongside transaction fees. The card with the absolute lowest purchase fee is not necessarily the only financial consideration.
For smaller everyday purchases, the main cost question is usually the foreign transaction fee. If both your debit and credit card charge no additional overseas purchase fee and use comparable card-network conversion, there may be relatively little difference in the basic currency-conversion cost.
At that point, budgeting and repayment behaviour become more important. A debit card can make it easier to spend only money you already have, while a credit card can separate travel spending from your current-account balance and potentially offer additional purchase protection where the requirements are met.
If your credit card charges foreign transaction fees but your debit card does not, the debit card may clearly be cheaper for routine purchases. The opposite can also be true.
This is why you should check the cards already in your wallet before applying for another product. You may discover that one of your existing cards already offers competitive overseas terms.
For many travellers, carrying access to more than one payment method is sensible. Cards can be declined, damaged, blocked by fraud systems or lost, and some merchants may not accept a particular network.
Using a suitable card for everyday spending while keeping another card securely as backup can reduce the risk of being left without access to money. A credit card may also be useful for qualifying larger purchases or hotel deposits, while a suitable debit card can be useful for accessing your own money.
Avoid storing every card and all your cash in the same wallet. If the wallet is lost or stolen, having a backup payment method stored separately can make an already stressful situation easier to manage.
You should also make sure you can access your banking apps and know how to freeze or report a lost card while outside the UK.
If your normal debit or credit card charges around 3% for overseas spending, a specialist travel card may be worth considering before a significant trip. Current UK travel-card products can offer fee-free foreign purchases and competitive currency conversion, although individual terms, eligibility requirements and withdrawal rules vary.
Do not choose a card solely because it is labelled a “travel card”. Check the foreign purchase fee, ATM withdrawal fee, withdrawal limits, exchange-rate treatment and, for credit cards, the APR and cash-withdrawal rules.
You should also avoid applying for unnecessary financial products simply to save a tiny amount on one short trip. Consider your expected overseas spending and calculate approximately how much your existing card would cost before deciding whether changing cards is worthwhile.
This is similar to the approach Saving Guide Hub recommends when deciding whether a financial product is worth paying for: calculate the real cost first rather than choosing based on the headline feature.
A 0% foreign transaction fee is useful, but it does not automatically mean every overseas transaction is completely free. An ATM may still charge its own fee, a credit card may still charge for cash withdrawals, and interest can still apply if you carry a credit-card balance.
You should also check whether the 0% fee applies worldwide and whether there are limits or excluded transaction types. Product terms can change, so information you remember from a previous holiday may no longer be accurate.
For credit cards, a fee-free overseas purchase can still become expensive if the balance is not repaid. For debit cards, you should ensure sufficient funds remain in the account so that holiday spending does not push you into an overdraft.
A good travel card removes unnecessary currency fees; it does not remove the need to manage your money carefully.
Before your trip, check the foreign transaction and cash-withdrawal fees for every card you are considering taking. Compare them with your expected spending rather than assuming your main current-account card will be cheapest.
When paying abroad, check the currency displayed on the terminal and consider paying in the local currency rather than accepting an unnecessary sterling conversion. For cash, use trusted ATMs and pay attention to any fee displayed before confirming the withdrawal.
If you use a credit card, have a plan to repay the balance in full and on time where possible. Interest on carried debt can quickly outweigh relatively small savings made on overseas transaction fees.
Finally, include card charges, cash withdrawals and exchange-rate costs in your holiday budget. Travel spending is easier to control when these costs are planned before departure rather than discovered on your statement afterwards.
A debit card has a straightforward budgeting advantage because you are generally spending money already held in your current account. Banking apps can make it easy to monitor the remaining balance and see transactions as they appear.
Credit cards can make holiday spending feel less immediate because the money does not leave your bank account at the point of purchase. This can be useful for cash flow, but it can also encourage overspending if you stop thinking about the balance as real money that must eventually be repaid.
If you know that credit cards tempt you to spend beyond your planned budget, saving a small amount in foreign transaction fees is unlikely to compensate for returning home with expensive debt.
Using sinking funds before travelling can help here. Saving towards the holiday gradually means you can enjoy the payment advantages of the right card without relying on borrowing to fund the trip itself.
There is no universal winner. A specialist fee-free debit card can be cheaper than a standard credit card, and a specialist fee-free credit card can be cheaper than a standard debit card. The individual card’s overseas fee structure determines the cost.
For routine purchases, compare the foreign transaction fee first. For ATM withdrawals, look specifically at cash fees and interest. For expensive purchases, also consider whether Section 75 protection makes a credit card more useful.
The cheapest overall strategy may therefore involve more than one card. You could use an appropriate fee-free card for normal spending, a suitable debit card for cash withdrawals and a credit card for qualifying larger purchases where Section 75 protection is valuable.
What matters is understanding the purpose of each card before you travel rather than making the decision at a foreign ATM or checkout.
Debit card vs credit card abroad is not really a question of which piece of plastic is inherently cheaper. The important difference is between cards designed for overseas spending and cards that add foreign transaction fees, withdrawal charges or expensive borrowing costs.
A suitable debit card can be excellent for everyday spending and cash access because you are using your own money. A suitable credit card can also offer competitive overseas spending while providing stronger legal protection for qualifying purchases through Section 75. However, withdrawing cash on a credit card or carrying the balance after your holiday can quickly make credit the more expensive option.
The Saving Guide Hub approach is to check your cards before travelling, understand every overseas fee and assign each card a clear purpose. Avoid unnecessary currency conversion, plan how you will access cash and never assume that a card advertised as convenient abroad is automatically cheap.
A few minutes spent checking your card fees before departure could save considerably more than trying to fix expensive travel spending after you return home.
Neither is automatically better. A debit or credit card designed for fee-free overseas spending can be inexpensive, while standard cards may charge foreign transaction fees. Credit cards can offer stronger protection for qualifying purchases, whereas suitable debit cards can be more practical for withdrawing cash.
It can be if your debit card does not charge foreign transaction or overseas spending fees. However, many standard debit cards can add currency-conversion or other charges, so check your bank’s current fee schedule before travelling.
A specialist travel credit card with no foreign transaction fee can be a cheap way to make purchases abroad. However, it can become expensive if you withdraw cash, incur other card-specific charges or fail to repay the balance and begin paying interest.
Some do. MoneyHelper says banks may add a currency-exchange fee, often around 3% of the transaction amount, when a debit card is used overseas or in a foreign currency. Other accounts offer fee-free overseas spending, so charges vary by provider.
When given a choice, paying in the local currency is generally worth considering, particularly when using a card with competitive overseas terms. Choosing pounds can involve dynamic currency conversion, where the merchant or ATM provider determines the conversion rather than your normal card arrangement.
Credit cards can be expensive for cash withdrawals because providers may charge a withdrawal fee and interest can start immediately. Check the card’s cash terms carefully before using it at an ATM.
For qualifying purchases, yes. Section 75 can cover credit-card purchases costing more than £100 and up to £30,000 when the legal requirements are met, including eligible overseas purchases. Debit cards do not receive Section 75 protection but may offer chargeback.
It can. Qualifying overseas purchases can receive Section 75 protection, although transactions involving intermediaries or certain payment structures can affect eligibility.
Yes. Debit-card purchases can potentially qualify for chargeback when something goes wrong. Chargeback is a card-scheme process rather than the statutory protection provided by Section 75.
Having a backup payment method can be useful if your main card is lost, damaged, blocked or declined. Keeping the backup separately from your primary card can also reduce the risk of losing access to all of your money at once.
