Changing Money in Korea Without Quietly Losing 6%
The board rate is not the rate you get. How commission hides inside a currency exchange in Korea, when a street booth is genuinely the best deal, and why most travelers now barely need cash at all.
The short answer
Ask one question before any exchange: "How many won will I receive for this exact amount?" The board rate is advertising. The number you receive is the deal. And in a country this cashless, the cheapest currency strategy is usually to exchange far less than you planned.
💱 Roughly how the options compare
| Method | Typical value | Watch out for |
|---|---|---|
| Card payment in won | Usually the best | Decline "charge me in my home currency" |
| Bank or global ATM withdrawal | Good, if your home fees are low | Machine-offered conversion, withdrawal fees |
| Licensed exchange office in the city | Often very good | Margin hidden in the quoted rate |
| Bank counter | Fair, slower | Paperwork, limited hours |
| Airport counter | Worst | Convenience pricing |
Where the loss actually hides
"The board showed a great rate, better than my bank at home. What I actually received was about six percent less. There was no fee listed anywhere — the commission was just inside the rate they used."
- Board rate ≠ applied rate
- ≈ 6% gap
- No visible commission line
Why this works: a rate is a ratio and nobody does ratio arithmetic while standing at a window with a queue behind them. A total is a single number you can check in one second. Always ask for the total.
Not every exchange booth is a bad deal — quite the opposite
Licensed exchange offices in Seoul's main shopping districts are competitive precisely because several of them sit within a hundred metres of each other and travelers compare. The problem is not the format, it is the specific window that quotes a headline rate and applies a different one. Comparing two windows on the same street takes two minutes and settles it.
The three habits that cover almost everything
- Ask for the receiving amount, not the rate"For 300 dollars, how many won?" Then check it on your phone against the mid-market rate. A gap of a percent or two is normal; six is not.
- Always be charged in wonAt ATMs and card terminals, decline conversion to your home currency. This one habit quietly saves more than the choice of exchange window.
- Count before you walk awayCount the notes at the counter, in front of the person who handed them to you. Once you have left the window, it is your word against theirs.
Signals of a fair window
- Gives you the total in won before you commit
- Shows the calculation on a screen
- Prints or writes a receipt
- Licence displayed on the wall
Signals to walk on
- Only a board rate, no total
- Rushing you while counting
- No receipt offered
- Anyone offering to change money on the street
How much cash do you actually need in Korea?
Less than almost anywhere else. Cards and mobile payments work in convenience stores, taxis, cafés, subway and most restaurants. Realistic cash needs: traditional markets, some street food, small older shops, and temple or festival stalls. A modest amount covers a week for most travelers, which turns the whole exchange question into a rounding error.
If you were shortchanged
The receipt is the case
Without a receipt showing the rate applied and the amount received, a shortchanging complaint is very hard to pursue. Take the receipt at the window and photograph it with the board visible if you can. Then call 1330 — English, Japanese and Chinese — and report which office, when, and how much.
The bottom line
Korea has one of the world's easiest payment environments, and a traveler who pays by card in won and exchanges a small buffer of cash at a window that quotes a total has already solved this entirely.
If an exchange office gave you a rate that was not the rate on its board, report it and write it up. Windows on a shopping street live and die on which one the next visitor walks toward.

Frequently asked questions
Where is the best place to exchange money in South Korea?
For most travelers the honest answer is: exchange very little. Korea is close to fully cashless, and cards work almost everywhere. When you do need won, licensed exchange offices in areas like Myeongdong and Namdaemun often beat bank counters and always beat airport counters, but only if you confirm the exact amount you will receive before handing over any money.
Do currency exchange booths in Korea charge commission?
Some build a margin into the rate rather than charging a visible fee, so the number on the board is not what you receive. The only figure that matters is the final amount in won for the exact amount you are handing over. Ask for that number, on a calculator screen if there is no shared language, before the transaction starts.
Should I exchange money at Incheon Airport?
Only the minimum you need to reach the city, if anything. Airport exchange rates are consistently among the worst available in Korea. Transport from the airport can be paid by card, so in practice most travelers need no cash at all before arriving in the city.
Is it better to use an ATM in Korea than to exchange cash?
Often, yes, provided your home bank's foreign transaction and withdrawal fees are reasonable. Look for ATMs marked Global or Foreign Card at banks and convenience stores. Always decline the machine's offer to charge you in your home currency — that conversion is done at the operator's rate, not your bank's, and it costs you money.
What is dynamic currency conversion and should I accept it?
It is the option a card terminal or ATM offers to bill you in your home currency instead of Korean won. It sounds helpful and is almost always more expensive, because the exchange rate is set by the terminal operator. Always choose to be charged in won.
