Savings by paying in local currency

How this calculator works
The market-rate reference converts the foreign amount using the entered U.S.-dollar value per foreign unit. The card-network path adds an editable difference from that reference, then applies the card’s foreign transaction fee and subtracts reward value.
Dynamic currency conversion is a separate quote
When a merchant or ATM offers to bill in U.S. dollars, that provider selects a conversion rate. The calculator models DCC as a markup over the same reference rate so the two paths can be compared.
U.S.-dollar billing may not avoid the card fee
Foreign transaction fees can apply to purchases outside the United States or with a foreign merchant even when the charge is denominated in dollars. Enter the applicable fee from the card agreement in the DCC path rather than assuming zero.
Processing date creates uncertainty
Card networks generally use a rate in effect when the transaction is processed. It may differ from the purchase date, posting date, a search-engine quote, or the merchant’s reference.
Decline or accept currency conversion only after seeing the offered exchange rate, markup, and total. ATM operator fees and cash-advance terms require a separate analysis.

Worked example
A 1,000-unit purchase at $1.10 per unit has a $1,100 reference value. A 0.5% network-rate difference converts to about $1,106 before the issuer fee.
With 2% reward value, the example still favors local-currency billing by about $37. Live rates and agreement terms control.

Questions people ask
What is a foreign transaction fee?
It is a card-plan fee for certain foreign-currency, foreign-merchant, or overseas transactions, often calculated as a percentage of the converted amount.
Should I pay in local currency or U.S. dollars?
Local currency often avoids a merchant DCC markup, but compare the displayed quote and your card agreement for the actual transaction.
Can my card charge a foreign fee on a U.S.-dollar purchase?
Yes, a cross-border or foreign-merchant transaction can trigger a fee even without foreign-currency conversion.
Does a no-foreign-fee card use the market exchange rate?
The network still selects a processing-date rate that may differ from a reference market quote; “no fee” refers to the issuer’s separate fee.
Are ATM withdrawals included?
No. ATM operator fees, cash-advance fees, and cash-advance interest can apply in addition to currency conversion.
