When a card terminal or ATM abroad asks whether to charge you in U.S. dollars or the local currency, choose the local currency. Picking USD triggers dynamic currency conversion (DCC), where the merchant’s provider sets the exchange rate and adds a markup. Paying in local currency lets your card network convert the charge, which is almost always cheaper.
What is dynamic currency conversion? #
DCC lets a foreign merchant or ATM charge your card in your home currency instead of its own. The terminal spots a U.S. card and offers two options: pay €100, or pay what it says is $1XX.
If you pick dollars, the merchant’s payment provider converts the amount at a rate it chooses, with a markup built in, and that markup is often shared with the merchant. That’s why clerks sometimes push the dollar option.
If you pick local currency, Visa, Mastercard or your issuer converts it at the network rate, which is typically close to the market rate.
In the European Union, Regulation (EU) 2019/518 requires DCC providers to disclose their markup as a percentage over the European Central Bank reference rate before you accept. That’s useful, because the disclosure is often the only place you see how much more you’re paying.
How much does paying in USD cost? #
Markups vary by provider, merchant and country, and they’re easy to underestimate because the price is shown in familiar dollars. Here’s an illustration with a €1,000 purchase, assuming a market rate of $1.10 per euro and a 5% DCC markup:
| Choice | Rate applied | Charged to your card |
|---|---|---|
| Pay in euros (network converts) | About $1.10 | About $1,100 |
| Pay in dollars (DCC at 5%) | $1.155 | $1,155 |
That’s $55 for a button press. Check the disclosed markup on the receipt or screen when you have one, since it’s the real price of choosing dollars.
Does paying in dollars avoid foreign transaction fees? #
No. Card terms decide when a foreign transaction fee applies, and many issuers charge it on any purchase processed outside the United States, even if it’s billed in dollars. Check your card’s pricing terms. Choosing USD doesn’t save you the fee, and it adds the DCC markup on top.
The real fix is a card with no foreign transaction fee. Two examples we checked in September 2026: Capital One’s Venture X and Savor cards charge no foreign transaction fee, while the Wells Fargo Active Cash charges 3% on foreign transactions (Capital One, Wells Fargo). A 2% card that charges 3% abroad earns less than nothing there.
How to decline DCC at the register and the ATM #
Read the terminal screen #
Terminals often make the dollar option the bright, easy button. Look for wording like:
- “Pay in USD?” Choose No, or the local currency.
- “Accept conversion rate?” Choose decline or without conversion.
- A screen showing two amounts. Pick the one in local currency.
Tell the cashier before they run it #
In restaurants and shops where staff handle the terminal, say “local currency, please” up front. If the receipt comes back in dollars with a conversion disclosure, ask them to void it and run it again in local currency. Card network rules require that you be offered a choice.
Watch for ATM “guaranteed rates” #
ATMs abroad often offer to “lock in” a rate or warn about unpredictable exchange rates. Decline the conversion and withdraw in local currency. Your bank will convert it for less.
Pick the right card before you go abroad #
Choosing local currency saves you the markup, and the card you pay with decides the rest. Before a trip, sort your wallet into cards that are fine abroad and cards that stay home. Credit Card Central keeps a notes field on every card, so writing “no FX fee” or “3% FX fee: domestic only” on each one takes a minute. Its Which Card? screen then ranks the cards you own for dining, travel, groceries and gas, so you can pick the best earner among the cards you’ve marked as safe abroad.
Travel cards often bring protections along too. If you’re renting a car on the trip, read does credit card rental car insurance cover liability. If you’re flying, Priority Pass guest rules covers lounge access, and the best Capital One transfer partners for flights covers using miles for the flights themselves.
Frequently asked questions #
Does paying in USD avoid foreign transaction fees? #
No. Many issuers charge their foreign transaction fee on purchases processed abroad even when you pay in dollars. You’d pay the DCC markup and the fee.
What if a merchant charges me in dollars without asking? #
Ask them to void the charge and rerun it in local currency. If they won’t, keep the receipt and contact your card issuer, especially if the receipt doesn’t show a disclosed conversion choice.
Does the local currency rule apply to debit cards? #
Yes. Debit cards face the same DCC prompts at terminals and ATMs. Choose local currency every time.
How do I know if my card has a foreign transaction fee? #
Check the card’s pricing and terms, the table that lists APR and fees. The fee is listed as a percentage of each foreign transaction, or as “none.”
