Credit card foreign transaction calculator
The purchase is converted first. The percentage is then added to that billing amount. A zero percentage means conversion only. You can type a card rate if the issuer did not use the mid-market rate, and a merchant total if a terminal offered to charge you in your billing currency. This page does not know your card number or your issuer’s fee.
