Should You Pay in Local Currency or USD?

When making international purchases, whether abroad or online, a common decision arises: whether to pay in the local currency or in U.S. dollars. This choice can significantly impact the final cost. Understanding the mechanisms behind these payment options allows consumers to make informed decisions that can lead to savings.

Understanding Dynamic Currency Conversion

The option to pay in your home currency, such as U.S. dollars, when overseas is typically due to Dynamic Currency Conversion (DCC). Merchants offer DCC, allowing a customer to complete a credit or debit card transaction in their card’s home currency rather than the local currency. The conversion happens immediately at the point of sale.

When DCC is offered, the system detects the card’s issuing country and presents the option to pay in the local currency or your home currency. If you choose to pay in your home currency, the merchant or their payment processor performs the currency conversion. This differs from paying in local currency, where your bank or card issuer handles the conversion. Merchants often offer DCC because they can earn a commission or a share of the conversion fee from the DCC provider, creating an additional revenue stream for their business. This service aims to provide immediate clarity on the cost in your familiar currency.

Key Factors for Your Decision

When choosing between local currency and U.S. dollars, two primary financial elements influence your decision: exchange rates and foreign transaction fees. The exchange rate offered through Dynamic Currency Conversion (DCC) typically includes a markup, making it less favorable than the rate your card network, such as Visa or Mastercard, would provide. This embedded markup means you usually pay more when opting for DCC.

Foreign transaction fees are charges applied by your credit or debit card issuer for purchases in a foreign currency, typically 1% to 3% of the amount. While these fees apply when paying in local currency, the exchange rate provided by your card network is almost always more competitive than DCC’s rate, even with the foreign transaction fee. Therefore, paying in local currency generally results in a lower overall cost than using DCC. Understanding your specific card’s terms regarding exchange rates and fees is beneficial.

Smart Payment Practices Abroad

When making international payments, consistently choose to pay in the local currency. This ensures your card issuer or network, which offers more favorable exchange rates, handles the currency conversion. Selecting U.S. dollars via Dynamic Currency Conversion (DCC) almost always results in a higher cost due to less competitive exchange rates from the merchant or their third-party processor.

Before traveling or making international online purchases, review your credit and debit card agreements for foreign transaction fees. Many travel credit cards offer no foreign transaction fees, providing a cost-effective way to make purchases abroad. Using such a card can significantly reduce international spending.

Notify your bank of travel plans to prevent your card from being flagged or declined, ensuring uninterrupted access to your funds. Regularly monitoring your bank and credit card statements after international transactions allows you to verify accuracy. When withdrawing cash from an ATM abroad, always choose the local currency to avoid unfavorable exchange rates from the ATM operator, similar to how DCC works for purchases.
