What Is DCC? This Checkout Option Costs You 3–5% More

When paying by card abroad or withdrawing from an ATM, you may have seen a prompt like: “Pay in RMB (guaranteed rate) or in local currency?” If you picked RMB, you fell for DCC (Dynamic Currency Conversion).

What DCC is

Normally you pay in the local currency and your card issuer converts it at its own rate. With DCC, the merchant or ATM operator converts the amount on the spot and charges you directly in your home currency. It sounds convenient — but they set the rate, and it is usually far worse than your issuer’s.

Why it costs so much more

• Issuers and card networks typically add around 1% on top of the reference rate
• DCC markups are commonly 3–5%, and the screen often shows only a “guaranteed rate” without telling you the markup
• On the same purchase, DCC can cost tens of dollars more than paying in local currency

How to spot it and refuse

• Card terminals: whenever you are asked to choose between your home currency and the local one, always choose the local currency — never CNY / Home Currency
• ATMs: keep choosing “Without Conversion” and say no to any “guaranteed rate”
• Online shopping: some overseas sites default to your home currency by IP — switch it back to the local currency before checkout
