Compare a card terminal’s currency conversion offer
How to read a dynamic currency conversion offer, compare it with your card terms and verify charges before paying abroad.
Quick answer: should I pay in local currency or my card’s billing currency?
Compare the exact amounts and costs shown for both choices, then apply your card issuer’s conversion rate and fees for the local-currency option. A DCC offer converts the purchase or ATM withdrawal at the merchant or ATM provider’s rate into your card’s billing currency; paying in local currency leaves conversion to your issuer or card network under your account terms. There is no universal answer for every card and transaction. Visa says the choice is yours after considering your objectives and conversion costs.
What is dynamic currency conversion (DCC)?
DCC is an offer, at a merchant terminal or ATM, to convert a foreign-currency transaction into the billing currency of your card at the point of payment. Mastercard’s guide describes the DCC conversion rate as offered by the acquirer; when a cardholder pays in local currency, the issuer provides the conversion under the card agreement. Your own issuer terms, transaction processing date and any separate fees affect the final charge.
What should the terminal or ATM show?
Before choosing, check the local-currency amount, card-billing-currency amount, both currency symbols, the conversion rate and any extra fee or markup. Visa says its merchants and ATMs should show these details and give cardholders a choice; Mastercard’s guide also lists the amounts, rate and additional fees as disclosures for DCC. Keep the receipt so you can compare it with the posted transaction.
How can I compare the two options?
First note the local amount and the DCC total in your card’s billing currency, including every displayed fee. Then estimate the local-currency option using your issuer’s expected exchange rate and foreign-transaction fee from the card agreement. A network rate calculator can be an estimate only: the rate used for a posted transaction and issuer fees can differ. If the terminal does not show the DCC amount, rate or fees clearly, or you feel pressured, Visa recommends declining the conversion offer and contacting your issuer.
What changes when I use an overseas ATM?
An ATM may offer DCC for the withdrawal and separately disclose an operator fee. Compare the converted withdrawal amount and disclosed conversion costs, and read the fee shown by the ATM before confirming. Your card issuer may also charge its own foreign-transaction or cash-withdrawal fees under your account terms. These charges are separate from the ATM’s conversion offer; check your issuer’s agreement for cash-advance rules.
What should I check before deciding?
Confirm which currency is your card’s billing currency, read both totals rather than relying on button wording, check the displayed rate and fees, and consult your issuer’s foreign-transaction and ATM terms. Keep the receipt and review the final posted amount. DCC availability, disclosures, issuer rates, fees and applicable rules vary by card, merchant, ATM, location and transaction. This checklist is general information, not a recommendation for a specific card.
