Foreign transaction fees: what they really cost you on a trip

A foreign transaction fee is a percentage, often 3%, that your card issuer adds to purchases made in a foreign currency, and under some card agreements also to purchases in U.S. dollars that are processed outside the United States. You avoid it in two moves: carry a card whose pricing table shows no foreign transaction fee, and when a terminal or ATM abroad offers to charge you in dollars, decline and pay in the local currency.

Where the fee comes from

When you pay abroad, the merchant’s bank sends the charge in the local currency through the card network, which converts it to dollars at its own exchange rate. The network charges your issuer an assessment on cross-border transactions. An issuer that charges a foreign transaction fee passes that cost on and adds its own markup; an issuer that advertises no fee absorbs it. What you see on your statement is one line: the converted amount plus the fee, or the converted amount alone.

The fee does not track the annual fee. Some no-annual-fee cards waive it and some cards with a fee still charge it, so check the specific card rather than assuming a premium card is travel-ready.

A €100 dinner, four ways

Take an illustrative exchange rate of $1.15 per euro, so the dinner is worth $115.00 at the network rate. Now assume your card charges 3% on foreign transactions, and that the restaurant’s terminal offers to charge you in dollars at a rate marked up 5% over the network’s. Here is what lands on your statement:

The last row is the one travelers pay without noticing. Accepting dollars at the terminal does not avoid your issuer’s fee if your card agreement charges it on transactions processed abroad, so the two costs stack: 8.15% over the network rate in this example (1.05 × 1.03).

Always pay in the local currency

The offer to pay in dollars is called dynamic currency conversion. The merchant’s payment provider sets the exchange rate and keeps the markup, and the screen shows you a rate rather than a fee, which makes the cost hard to see. Some terminals pre-select dollars or word the choice as if it protects you from exchange-rate surprises.

The rule is simple to apply: choose the local currency every time, at restaurants, hotels, car rental counters and ATMs. If a receipt shows a dollar amount and an exchange rate you did not choose, ask the merchant to void it and run the charge again in the local currency.

How to check your card before you travel

Do not rely on the card’s name or its marketing. Every card application and account-opening disclosure includes a standardized pricing table, often called the Schumer box after Charles Schumer, who sponsored the 1988 law that created it as a member of the House. Under the transaction fees, look for the line for foreign transactions. It will show a percentage of each transaction in U.S. dollars or say “None.” The same table is in your cardmember agreement online.

Also read how the agreement defines a foreign transaction. If it covers charges “processed outside the United States,” you can pay the fee on an online purchase from a foreign seller even though you never left home and the price was in dollars.

Our catalog shows whether each of these cards charges the fee, next to its annual fee tier; confirm on the issuer’s pricing table before a trip, since terms change.

Debit cards and cash abroad

Debit cards can carry a foreign transaction fee too, and your bank’s fee schedule says so. Cash from a foreign ATM can cost up to three charges: your bank’s fee for using an out-of-network ATM, the ATM owner’s own fee, and a foreign transaction fee on the amount. Fewer, larger withdrawals keep the flat fees down. Some banks and brokerage accounts reimburse ATM fees worldwide; check yours before you go, and compare it with checking accounts without monthly fees if you travel often.

Avoid using a credit card at an ATM. That is a cash advance, with its own fee, a higher APR and interest from the first day, as the true cost of a cash advance shows.

A checklist before you leave

1. Read the foreign transaction line in the pricing table of every card you plan to bring, and leave home any card that charges it if you have one that does not.
2. Bring two cards on different networks. Visa and Mastercard are the most widely accepted abroad, and a second card keeps you paying if the first is declined or frozen after a fraud alert.
3. Look up your bank’s fees for foreign ATMs and whether it reimburses the ATM owner’s charge.
4. Turn on transaction alerts in your issuer’s app, so each charge shows up with its dollar amount while you can still question it at the counter.

For most trips, the cheapest setup is a credit card with no foreign transaction fee for purchases, a debit card with low or reimbursed ATM fees for the cash you need, and the local currency every time a screen asks. If you are choosing a travel card with an annual fee, run the numbers in when an annual fee is worth it.
