Bank Fee and Preference Table

Compare the same amount, same currency, and same pickup method. Start with the MillionsCode global exchange calculator, then check final quotes inside each banking app. For overseas shopping, also review overseas shopping exchange savings.

Airport, Branch, and App Exchange

Airport exchange is convenient, but a walk-up counter can carry a weaker preference. App order with airport pickup often gives a better balance. Confirm terminal, counter hours, and same-day pickup rules before departure. A city branch is better for larger cash amounts or less common currencies, but inventory can vary.

Foreign-Currency Accounts and Travel Cards

A foreign-currency account works when you want to buy gradually and hold USD or JPY before travel, study, or business payments. Travel cards are useful for repeated card payments abroad, but ATM fees, refund policy, and local merchant currency choice still decide the final cost. For crypto-related conversion, separate bank exchange spread from exchange spread; when relevant, review Binance fee referral only after checking local rules.

Timing Your Exchange

Timing is risk management, not prediction. Split a large travel budget over two to four weeks instead of relying on one quote. For context, read the USD/KRW 10-year analysis. For Japan travel, the JPY exchange guide explains why yen quotes and 100-yen units need separate attention.

FAQ

Which bank is always cheapest?

There is no permanent winner. Compare final app quotes before trading.

Is airport exchange always expensive?

Walk-up airport counters can be less favorable, but app pre-order with airport pickup can be practical.

Does 90 percent preference mean zero fee?

No. It usually discounts the bank spread and the final cash rate may still differ from the base rate.

When do travel cards help?

They help for repeated payments, but ATM, refund, and merchant currency rules still matter.

Should I split the exchange?

Splitting larger budgets over several dates reduces exposure to one bad quote.

What currency should I pay in abroad?

Local currency is usually safer than KRW dynamic currency conversion unless the total is clearly better.
