A 50 euro dinner in Paris rarely costs exactly 50 euros of your money. The card networks convert the currency, and your issuer may add a line of its own. Then a waiter may ask whether you want to pay in dollars. That one question can change the price again.
What a foreign transaction fee is
When a purchase involves a foreign currency, the money has to be converted. According to a General Services Administration (GSA) SmartPay bulletin on foreign currency conversion, Visa and MasterCard impose fees on transactions that involve conversion. Those fees show up on the statement as a separately identified charge. The bulletin gives an example of a US cardholder in Europe who buys a meal priced in euros. The meal appears on the statement, and a currency conversion fee appears next to it.
One caution. That bulletin is written for government travel, purchase, and fleet cards. The sources used for this article do not explain how these fees apply to ordinary consumer credit or debit cards. Treat it as a description of how the system works, not a rate card for your wallet.
The same bulletin says the names and mechanics of the fees differ between the two networks, and that issuers may charge them when they are disclosed to the cardholder, typically in the materials mailed with the card. It also says the overall assessment is complicated and its overview does not cover every aspect. So the label on your statement may not match what a friend sees on theirs.
Whether your own card charges a fee is a question only your card agreement can answer. Some issuers may waive the fee on certain travel cards, but the sources here do not confirm that, so check yours rather than assume.
Dynamic currency conversion at the terminal
Dynamic currency conversion, or DCC, is a separate thing. Some merchants outside the US offer to charge you in US dollars instead of the local currency. The GSA bulletin says the conversion then happens at the merchant's rate rather than the card's rate, and calls this generally the less cost-effective option.
The offer usually comes as a quick question at the register: dollars or euros? Dollars feels familiar, which is the appeal. But you are agreeing to the merchant's exchange rate, and you may not see it spelled out.
Here is how to decline it in practice:
- When the terminal or the cashier asks, choose the local currency.
- If the screen shows both totals, pick the one in the local currency, such as euros.
- Check the receipt before you sign. It should show the local currency amount.
- If you were charged in dollars after saying no, ask for it to be reversed before you leave.
The sources do not describe a formal consumer right to decline DCC or a process to dispute these charges. Asking at the counter is the practical step available. For anything beyond that, the Consumer Financial Protection Bureau (CFPB) is the place to look for current guidance.
A worked example, with made-up numbers
None of the sources give a percentage or dollar range for foreign transaction fees or DCC markups. So the numbers below are purely illustrative. They are not typical figures.
Say a dinner costs 100 euros. Suppose your card adds a hypothetical 3 percent fee on foreign purchases. Your cost is the converted amount plus 3 percent of it. Now suppose a merchant offers DCC and its rate adds a hypothetical 5 percent over the card's rate. That is a different, separate markup, and it may or may not be disclosed on screen. The point is the method. Find the percentage in your own agreement, multiply it by your planned spending, and compare it with any DCC offer you see.
Where to look in your paperwork: the fee schedule or rates and fees table in your cardholder agreement. Search the document for the words foreign, currency, or international. If the fee goes by another name, the CFPB notes that cards may use different words for similar fees. The phone number on the back of the card can confirm it.
Prepaid cards, if you plan to use one
Prepaid cards come with their own fee structure. The CFPB says most charge fees for holding or using the card, including activation, maintenance, and transaction fees. Types and amounts vary by card and by how it is used. The sources do not say how these cards treat foreign purchases, so ask about that directly.
The monthly fee is a fixed charge taken from the balance even if you never use the card. Some cards waive it, for example when pay or benefits are direct deposited. Under a pay-as-you-go plan, a card may charge a fee for each in-store or online purchase. Some cards let you choose between the two plans. The CFPB says a monthly fee may be cheaper than per-transaction fees if you use the card often. For a card that mostly sits in a drawer, the math can tip the other way.
Questions to ask and what to watch for
Before you leave, call the issuer or read the agreement and get answers to these:
- Does the card charge a fee on purchases in a foreign currency, and what is it called?
- Which other fees apply: activation, monthly, transaction, or others? Can any be waived, and how?
- If a merchant offers to charge in dollars, how does that compare with paying in local currency?
Two warning signs are worth knowing. The GSA bulletin says these fees are permitted when disclosed, so a fee that appears nowhere in your card materials deserves a call to the issuer. And a monthly fee that keeps running on an unused card is a drain you can avoid by asking about waiver conditions up front.
