Pay in local currency: the card machine question that costs you money
When a card machine abroad offers to charge you in your own currency, say no. Here is why, and what it costs when you say yes.

The short version
- When a card machine or cash machine abroad offers to charge you in your home currency, that is dynamic currency conversion (DCC).
- It feels helpful. It almost always costs more, often several percent and sometimes over 10%.
- Always choose to pay in the local currency. At a cash machine, choose "decline conversion".
- Pair that with a card that has no foreign transaction fee and you pay close to the real exchange rate.
You are paying for dinner abroad. The waiter hands you the card machine and it asks a friendly question: pay in the local currency, or in euros (or pounds, or dollars)? Your own currency feels safer. You know what it means. So you tap it.
You just paid extra. Not a lot, maybe. But it happens on every meal, every hotel, every cash withdrawal, and it adds up over a trip.
What dynamic currency conversion is
When you pay with a card in another currency, someone has to convert it. Normally that is your own card network and bank, which use a rate close to the real market rate. Dynamic currency conversion lets the shop’s payment provider do the conversion instead, on the spot, at a rate it chooses.
That rate includes a markup, and the shop and the provider share the profit. That is why the machine asks you so nicely.
How much it actually costs
Say your trip involves €1,500 of card spending and a few cash withdrawals. With a card that has no foreign fee, you pay close to the real rate. Accept DCC every time at a 6% markup, and you hand over about €90 for nothing. On a cash machine with a worse markup, it can be more.
| You spend | With 1% card fee | With DCC at 6% | With DCC at 10% |
|---|---|---|---|
| €100 dinner | €1 | €6 | €10 |
| €500 hotel | €5 | €30 | €50 |
| €1,500 trip | €15 | €90 | €150 |
Where it shows up
- Card machines in shops, restaurants and hotels, as a choice between two currencies.
- Cash machines, often worded as "accept conversion" or "we guarantee your rate". The guarantee is that it will be a bad one.
- Online checkouts on foreign websites and booking sites, sometimes pre-selected for you.
- Hotel and car rental bills, where staff may ask, or simply choose for you at checkout.
Watch out: some machines show your home currency as the big, highlighted button. Read the screen before you tap. If staff choose for you, you can ask them to run the payment again in the local currency.
How to avoid it, every time
- Always pick the local currency. In Hungary, pay in forint. In the US, pay in dollars. If the screen shows two amounts, choose the one in the currency of the country you are in.
- At cash machines, decline the conversion. The wording varies, but the option you want is the one that does not convert.
- Online, check the currency before you confirm. If a foreign site offers to charge you in your currency, switch it to theirs.
- Use a card with no foreign transaction fee. Many banks charge around 1% to 3% on foreign card payments. Several cards and money apps charge nothing on top of the network rate. This is where most of your saving comes from.
- Check your statement. If you see a conversion you did not agree to, raise it with the merchant and then your card provider.
Within the EU, rules introduced in 2020 require the DCC markup over the European Central Bank reference rate to be shown before you pay, for payments in EU currencies. That helps, but only if you read the screen. Outside the EU, you may see no warning at all.

Very rarely. If your own card charges a big foreign transaction fee, a DCC offer can occasionally come out close. But it almost never wins, and you cannot easily check in the five seconds you have at the till. The simple rule saves you more than the rare exception: local currency, every time.

The bottom line
Dynamic currency conversion is a convenience you pay for, and the price is hidden in the rate. Choose local currency, decline conversion at cash machines, and carry a card with no foreign fee. Three habits, and you keep the money that would have quietly gone to someone else. For a bigger picture of where exchange costs hide, see how exchange rate margins work.
