You may know to avoid cards with foreign transaction fees when you’re making purchases abroad, but many travelers overlook the fact that payment networks offer different foreign exchange rates. TPG Senior Points & Miles Contributor Jason Steele investigates which network gets you the best deal, and provides some top picks for cards to use overseas. 

Even if you only travel overseas occasionally, you should be concerned with getting the best foreign exchange rates. Thankfully, credit cards offer some of the most favorable rates compared to other forms of currency conversion, but that doesn’t mean all cards offer the same rate. In today’s post, I want to take a closer look at how credit card exchange rates are calculated by the major payment networks, and help you choose the best card for your foreign purchases.

How Foreign Exchange Works with Your Credit Card

Credit cards can be used in nearly every country on earth, but there are several factors that determine how much you’re charged when you make a purchase in a foreign country. The most important issue is whether or not your card imposes a foreign transaction fee on charges abroad. Sadly, most credit cards still add a fee of up to 3% (2.7% for American Express cards) to all charges merely processed outside of the United States, including foreign purchases made from home and even those charged in US dollars. And while there’s a growing number of travel rewards cards that no longer impose this fee, the simple fact is that there’s no significant additional cost for credit card companies to handle a charge processed outside of the US, so these fees are pure profit and should be avoided at all costs.

Another factor that can impact your credit card’s foreign exchange rate even more seriously is a scam called dynamic currency conversion. Briefly put, this is when a retailer and a credit card processor offer a “service” that shows the transaction amount in your home currency. The problem is that this adds substantially to the currency exchange rate — often between 5-10% — and to the profit of both the merchant and the credit card processor, sometimes without the actual consent of the customer. Fortunately, this problem doesn’t appear to affect payment processors for American Express, just Visa and Mastercard.

The third-most important fact in your credit card’s exchange rate is the payment network it belongs to, such as Visa, Mastercard or American Express. Although these companies use interbank exchange rates — which offer much more favorable rates than other methods of currency conversion — you can get different rates depending on which payment network your card belongs to.

Comparing Visa and Mastercard Exchange Rates

Mastercard offers slightly better rates than Visa in most cases.

The world’s most popular payment networks, Visa and Mastercard, are also the most transparent when it comes to how they set their credit cards’ foreign exchange rates. Visa offers its exchange rate calculator, while Mastercard makes its Mastercard Currency Conversion Tool available online. If you play with these two tools long enough, you’ll start to notice a pattern: Mastercard usually has a small — though occasionally quite significant — advantage when it comes to foreign exchange rates.

I compared Visa and Mastercard’s exchange rates for eight major currencies for August 15, 2016, and here’s what I found:

  • Mastercard offered a 0.48% better rate for Australian Dollars.
  • Mastercard offered a 0.29% better rate for Canadian Dollars.
  • Mastercard offered a 0.62% better rate for Great British Pounds.
  • Mastercard offered a 0.18% better rate for Brazilian Reals.
  • Visa offered a 0.05% better rate for Euros.
  • Mastercard offered a 1.1% better rate for Mexican Pesos.
  • Mastercard offered a 0.009% better rate for Hong Kong Dollars.
  • Visa and Mastercard offered identical rates for Japanese Yen.

While American Express doesn’t publish its daily exchange rates, according to many reports it’s more comparable to Visa’s rates than Mastercard’s, which means that Mastercard should offer you a slightly better rate than either Visa or American Express.

While these fractions-of-a-percent differences might not seem like a big deal to most people, many award travel enthusiasts do care about these small margins. For example, we can (justifiably) get very excited when a new card offers an additional half a point per dollar spent and be very disappointed when a credit card imposes a 3% foreign transaction fee. In this context, the difference between a good deal and a bad one can easily be a just few tenths of a cent on TPG’s valuation chart.

That’s why it’s worth paying attention to the differing exchange rates offered by payment networks. I don’t see myself pulling up the latest exchange rates before every foreign purchase that I made, but I would pay attention to the current exchange before making a large purchase.

For example, if you were planning to spend thousands of dollars on airfare, hotel reservations or a cruise from a foreign operator, it would be worth taking a moment to see if the current exchange rate differs dramatically between payment networks. If I were to buy a $5,000 vacation package from a British tour operator on August 15, I’d be losing 0.62% in value for each dollar spent by using Visa instead of Mastercard. To put it another way, it would have cost me $31 more to put that charge on my Visa or Amex card than to pay with a Mastercard.


Here are six travel rewards cards to consider for large foreign purchases. They’re all part of the Mastercard network, so in general you’ll enjoy the lowest foreign exchange costs.

1. Citi Prestige Card — This card currently offers 40,000 bonus points after you spend $4,000 in purchases within three months of account opening. It offers 3x ThankYou points for air travel and hotel purchases, 2x on dining and entertainment and 1x elsewhere. Among its numerous features are Admiral’s Club access (though this benefit is ending in July of next year), Priority Pass Select lounge access, a fourth night free at hotels and a $250 annual airline travel credit. Though the card is eliminating some key perks next year, it could still be worth it thanks to the 4th Night Free benefit alone. There’s a $450 annual fee for this card, and no foreign transaction fees.

2. Citi Premier® Card — While it’s unfortunately not offering a sign-up bonus currently, this card features a solid 3x ThankYou points for travel purchases (including gas), 2x points on dining and entertainment and 1x elsewhere.

There’s an $89 annual fee for this card (waived the first year), and no foreign transaction fees.
