Wallet Math
한국어Type in the terms of the cards you already hold and it works out where each won should go, and how many cards are still worth holding.
We hold no list of cards. You copy the terms from your own agreement and statement, and nothing you type leaves this screen.
Empty fields stay out of the arithmetic. We have filled in nothing for you.
What a payment abroad actually costs you
Enter the foreign amount, the rate on your statement and the two fee rates your card charges, and the billed figure is laid out line by line.
Both fee rates are in your card agreement or in the overseas usage notice inside the issuer app. For the added rate, divide the won figure on the receipt by the foreign figure.
Enter numbers and the result appears here.

What this does not do
It never says one card is better. We hold no card names, no benefit tables and no annual fees, and it only does arithmetic on the terms you give it.
It does not fetch exchange rates. Use the rate printed on your statement if you want the figure to match what you were charged.
It handles reward points only. You are free to write in the name of a payment service, and we use no logo and no brand colour.
It does not read your agreement for you. Which spending counts toward a monthly requirement differs by card, and that answer is in your own terms.
