As the summer travel season approaches, this is a friendly reminder to avoid "dynamic currency conversion" (DCC) when making credit card purchases outside of your home country. DCC gives you the option of selecting a payment amount in your home currency rather than in the local currency. Typically, when presented with a credit card reader at a shop or restaurant, the touch screen will show purchase amounts in the local currency and in US dollars (for those with American credit cards) and you have the opportunity to choose. I have been seeing these “offers” for several years now and have learned, after doing a little mental math, they are almost always a bad deal for the purchaser. When presented with a credit card reader, I always choose to pay the amount shown in local currency rather than the amount shown in US dollars. During a recent trip, I was making purchases in Euros, Hungarian Forints, and Czech Korunas. From what I could tell, the option of paying in dollars inflated the cost of the purchases around an average of five percent (5%). Once, a card reader screen acknowledged that making the purchase in dollars added an eight percent (8%) fee. Even a credit card with a foreign transaction fee (which you should avoid using when traveling abroad) would have added only three percent (3%) to the tab. Currency games aside, Visa and MasterCard offer reasonable exchange rates when you choose to pay in the local currency. Upon returning home, our credit card statements showed exchange rates that were quite close to market rates. It is reasonable and fair for the credit card issuers make a fraction of a percent here and there as they are performing a service and accepting currency risk (although very briefly). But, claiming to offer a “preferential” rate to pad their bottom line is disingenuous. Because exchange rates are reasonable, using credit cards while traveling abroad is still worthwhile for a points and miles program as long as you avoid cards with foreign transaction fees. Travel oriented cards can offer 2X and 3X spending bonuses for transportation and restaurants to give you a leg up on saving money and accumulating points or miles for your next vacation.
