What you keep = premium − overseas trading fee − withdrawal fee − Korean trading fee − slippage
How it works out the won you keep when you buy a coin with your amount on one exchange, send it minus the withdrawal fee and sell it on the other. Overseas amounts are converted at the exchange rate the site uses.
The calculation at a glance
Good to know
Choose an exchange yourself and only the routes with it are calculated; leave it open and every route (4 Korean × 13 overseas exchanges) is compared at once.
The coin is bought along each exchange’s order book for the amount you enter. The average price the order fills at, pushed past the best price, is the real purchase price.
Check points
Sending the bought coin to the Korean exchange costs a withdrawal fee. The fee is fixed per coin whatever the amount, and the order books come from the exchanges’ public APIs at the moment you calculate (refreshed about every 15 seconds).
Check points
The coin that arrives is sold for won on the Korean exchange, and its trading fee applies. Trading fees come from a table of the exchanges’ official rates; coupon discounts are left out and the standard rate is used.
Check points
On both the overseas and the Korean exchange, an instant order fills at the prices it really reaches in the order book, not at the best price shown, so it changes the real result. The bigger the amount, the bigger the slippage.
Check points
Withdrawal fees are fetched every 6 hours from Bithumb, Coinone, Digital X (Korea) and Bitget, Bitfinex, BTC Markets (overseas); the others come from the fee table. An unknown withdrawal fee counts as 0, and the routes are shown from the best one down.
Check points
How CoinGaja calculates the kimchi premium itself is written on the premium basis page, and the premium of the whole Korean market is on the CoinGaja kimchi premium index.

FAQ
Questions people often ask while using CoinGaja.
When you buy a coin on an overseas exchange and send it to a Korean exchange to sell (overseas → Korea), or move it the other way (Korea → overseas), it takes the trading fees, the withdrawal fee and the order-book slippage out of the kimchi premium and shows the Korean won you actually keep. Every route between 4 Korean and 13 overseas exchanges is compared on the order books of that moment.
When the trading fees, the withdrawal fee and the slippage together cost more than the premium, the trip loses money. The withdrawal fee is the same whatever amount you send, so the smaller the amount, the bigger its share.
Moving 1,000,000 won or more between a Korean exchange and an overseas exchange that is not on its Travel Rule partner list falls under the Travel Rule: you have to finish an identity check before the transfer goes through. These routes are still ranked, and their calculation steps say so.
Trading fees come from a table of the exchanges’ official rates; its date is shown under the results. Withdrawal fees are fetched from Bithumb, Coinone, Digital X, Bitget, Bitfinex and BTC Markets every 6 hours and taken from the table for the others. When an exchange’s withdrawal fee is unknown, it counts as 0 and the calculation steps say so.
The result uses the order books at the moment you press the button. Prices and the premium can move while the coin is on its way, and fee discounts or events count only as far as the table records them. For information only, not investment advice.
