Introduction

Understanding currency exchange is an important part of planning a medical tourism trip to Korea. International patients visiting Seoul may need to pay for dermatology treatments, consultations, accommodation, transportation, food, shopping, and other travel expenses. Knowing how the Korean won works and where to exchange foreign currency can help you avoid unnecessary fees and make it easier to manage your treatment budget.

South Korea uses the Korean won (KRW, ₩). Major international currencies such as U.S. dollars, euros, British pounds, Australian dollars, Canadian dollars, Japanese yen, and Chinese yuan can generally be exchanged in Korea. International patients can also use internationally enabled credit and debit cards at many clinics, hotels, restaurants, and shops. However, having some Korean won available is useful for smaller purchases, transportation, markets, and businesses that may not accept foreign cards.

Understanding the Korean Won

What Is KRW?

The official currency of South Korea is the Korean won, abbreviated as KRW and commonly represented by ₩.

Korean prices can initially look large because the won has relatively small unit values compared with currencies such as the U.S. dollar.

For example:

• ₩1,000 = one thousand won
• ₩10,000 = ten thousand won
• ₩50,000 = fifty thousand won
• ₩100,000 = one hundred thousand won
• ₩1,000,000 = one million won

For medical tourists, becoming comfortable with these numbers is particularly important because cosmetic dermatology and aesthetic treatment prices can range from tens of thousands to several million won.

What Is the Current USD to KRW Exchange Rate?

Use Exchange Rates as a Moving Target

Exchange rates change throughout the day, so international patients should not rely on a fixed conversion rate when preparing a medical treatment budget.

As an illustrative current rate, US$1 was approximately ₩1,438.39 on July 31, 2026. This means:

USD AmountApproximate KRW Value$10₩14,384$50₩71,920$100₩143,839$500₩719,195$1,000₩1,438,390$2,000₩2,876,780$5,000₩7,191,950

These figures are illustrative conversions using that quoted rate, not guaranteed exchange amounts. Your bank, card issuer, exchange provider, or clinic may use a different rate after spreads, fees, or other charges.

Why Exchange Rates Matter for Medical Tourism

Small Differences Can Become Significant

Exchange-rate differences may seem minor when purchasing food or transportation.

However, the impact becomes more noticeable when paying for expensive medical treatments.

For example, suppose a treatment costs:

₩2,000,000

At an illustrative rate of ₩1,438.39 per US$1, the mathematical conversion is approximately:

US$1,391

If your actual card or exchange rate is less favorable, the amount charged in your home currency can be higher.

This is why patients should consider the total exchange cost, rather than simply looking at the advertised exchange rate.

How Much Korean Won Should Medical Tourists Carry?

For a Short Medical Trip

You do not necessarily need to exchange your entire treatment budget into cash.

For a three- to five-day Seoul trip, a practical cash reserve might be:

₩100,000–₩300,000 per person

for smaller everyday expenses, depending on your travel style.

This can cover expenses such as:

• Meals
• Coffee
• Snacks
• Local transportation
• Small purchases
• Convenience stores
• Miscellaneous expenses

Your major medical expenses can often be paid using a suitable international card or another accepted payment method, depending on the clinic.

For a One-Week Trip

For a seven-day medical tourism trip, you might consider keeping approximately:

₩200,000–₩500,000

available for everyday spending.

This is separate from your medical treatment budget and accommodation costs.

Should You Bring Cash to Korea?

Cash Is Still Useful

Although South Korea has extensive card and digital payment infrastructure, carrying some Korean won remains practical.

Cash can be useful for:

• Small restaurants
• Traditional markets
• Street food
• Small shops
• Some transportation situations
• Small purchases
• Backup spending

You do not necessarily need to carry a large amount of physical cash.

Avoid Carrying Your Entire Medical Budget in Cash

International patients traveling with substantial treatment budgets should generally avoid carrying all of their money as physical currency.

Large amounts of cash can create:

• Security concerns
• Loss or theft risk
• Exchange-rate management issues
• Problems if your travel plans change

Instead, consider using a combination of:

Cash + international card + backup payment method

Where Can You Exchange Currency in Korea?

Incheon International Airport

Airport exchange counters are convenient because they are available immediately after arrival.

However, convenience does not always mean the best exchange rate.

If you only need enough Korean won to reach your hotel, consider exchanging a modest amount at the airport and comparing other exchange options later.

Banks

Major Korean banks provide foreign currency exchange services, subject to their current operating policies and identification requirements.

Banks can be useful for travelers who prefer a regulated and familiar exchange environment.

Licensed Currency Exchange Offices

Currency exchange offices in central Seoul are another popular option.

Areas with large numbers of international visitors, including Myeongdong, have numerous exchange businesses.

Rates can vary between providers, so compare the displayed rate and any applicable fees before completing the transaction.

Hotel Currency Exchange

Some hotels may offer currency exchange services.

This can be convenient, but hotel exchange rates may not always be as competitive as specialized exchange providers.

Check the rate before deciding.

Should You Exchange Money at Incheon Airport?

Exchange Only What You Need Initially

One practical strategy is to exchange enough money for your immediate needs:

• Airport transportation
• Food
• Small purchases
• Emergency expenses

Then compare exchange rates in Seoul before exchanging a larger amount.

For example, if you need ₩100,000 immediately, exchanging that amount at the airport may be more convenient than spending time searching for another exchange office.

For a large amount, however, even a small rate difference can become meaningful.

Myeongdong Currency Exchange

Why Myeongdong Is Popular

Myeongdong is one of Seoul's best-known areas for international visitors and is also convenient for travelers staying near central Seoul.

The district has numerous currency exchange businesses, making it relatively easy to compare rates.

However, patients should still verify:

• The exact exchange rate
• Whether fees are included
• The amount they will receive
• Whether identification is required

Do not assume that every exchange office in the same neighborhood offers identical rates.

Using Credit Cards in Korea

Cards Are Widely Accepted

Major international credit and debit cards are commonly accepted at:

• Dermatology clinics
• Hospitals
• Hotels
• Department stores
• Shopping centers
• Restaurants
• Cafés
• Major tourist businesses

Visa and Mastercard are particularly common, while acceptance of other card networks can vary.

Check Your Card Before Traveling

Before leaving home, contact your card issuer or check your banking app to confirm:

• International transactions are enabled
• Your card is not blocked for overseas use
• Your daily spending limit
• Your foreign transaction fee
• Your cash withdrawal policy
• Your emergency contact information

Should You Pay for Medical Treatment by Card or Cash?

Ask the Clinic Before Your Appointment

Payment policies vary between clinics.

Before traveling, ask your chosen clinic:

• Which cards are accepted?
• Is payment processed in KRW?
• Is there a card surcharge?
• Are deposits refundable?
• Is a deposit required?
• Can treatment be paid in installments?
• Are refunds processed to the original card?

This is especially important for expensive treatment packages.

Paying in KRW

If a clinic quotes a treatment price in Korean won, paying in KRW can make it easier to compare the cost with your exchange rate.

It also helps you understand exactly how much the treatment costs in the local currency.

Dynamic Currency Conversion: What Is It?

Be Careful When Paying by Card

Some payment terminals may offer to charge your card in your home currency instead of Korean won.

This is known as dynamic currency conversion (DCC).

For example, a terminal might offer:

₩500,000 KRW

or:

US$XXX

The home-currency amount may include an exchange-rate markup.

When given the choice, travelers often prefer to have the transaction processed in KRW and allow their card issuer to handle the currency conversion, provided their card's terms make that advantageous.

Always check your own card's foreign transaction fees and exchange-rate policy.

Foreign Transaction Fees

Check Your Bank's Fee Structure

Your card issuer may charge a foreign transaction fee on purchases made in Korea.

For example, if your bank charges a 3% foreign transaction fee, a ₩1,000,000 purchase could incur an additional cost equivalent to approximately ₩30,000.

Some travel-focused cards have no foreign transaction fee.

Before your trip, compare your available cards and choose one with favorable international transaction terms.

Using ATMs in Korea

International ATM Access

International visitors can use certain Korean ATMs to withdraw Korean won.

Look for ATMs that explicitly support international cards.

The availability of international withdrawals can vary by location and ATM operator.

Potential ATM Fees

An ATM withdrawal can involve several different charges:

• Korean ATM fee
• Your bank's international withdrawal fee
• Foreign exchange spread
• Possible network fees

Because of this, withdrawing a small amount repeatedly may become expensive.

If you use an ATM, check the displayed fees before confirming the transaction.

Choose the Correct Currency Conversion Option

If an ATM offers to convert the withdrawal into your home currency, compare the offered rate carefully.

You may prefer to have the transaction processed in KRW, depending on your bank's exchange terms.

Cash Exchange vs. ATM Withdrawal

Cash Exchange May Be Better When

You already have foreign cash and want to convert it into KRW.

This can be convenient if you are carrying:

• U.S. dollars
• Euros
• British pounds
• Australian dollars
• Japanese yen

Compare the exchange rate before committing to a large transaction.

ATM Withdrawal May Be Better When

You do not want to carry significant foreign cash.

Using a debit card at an international ATM can provide convenient access to Korean won.

However, check all applicable fees first.

Currency Exchange for Medical Treatment

Create a Separate Medical Budget

A useful strategy is to separate your trip finances into categories:

ExpenseExample Budget CategoryMedical treatmentMain treatment budgetAccommodationHotel budgetTransportationAirport + local transportFoodDaily spendingCurrency feesExchange/ATM/card feesShoppingOptional spendingEmergency reserveBackup funds

This makes it easier to avoid accidentally spending money reserved for treatment.

Keep an Emergency Reserve

International patients should consider maintaining a backup amount separate from their everyday spending money.

An emergency reserve can help cover:

• Additional clinic visits
• Medication
• Unexpected transportation
• Hotel changes
• Flight changes
• Additional treatment
• Other unexpected expenses

Currency Exchange for High-Cost Treatments

Plan Large Payments in Advance

If your treatment costs several million won, exchange-rate fluctuations can have a noticeable effect.

Suppose your treatment costs:

₩5,000,000

At the illustrative rate of ₩1,438.39 per US$1, that is approximately:

US$3,476

If your home currency is different from USD, you will need to calculate the final amount using your own currency's current rate.

Do not assume that a price quoted in KRW will translate into the same home-currency amount several weeks later.

Avoid Last-Minute Currency Decisions

If your treatment is expensive, review exchange rates and payment options before traveling.

Your clinic may also require a deposit or advance payment, so confirm the payment schedule well before your appointment.

Currency Exchange for Travelers From Different Countries

U.S. Travelers

U.S. patients should monitor the:

USD → KRW

rate.

Because many international medical tourism websites quote prices in USD for comparison, it can be helpful to compare the clinic's KRW price against your card's actual conversion rate.

Australian Travelers

Australian patients should monitor:

AUD → KRW

and remember that the exchange rate between USD and KRW does not directly represent their final cost.

Canadian Travelers

Canadian patients should use:

CAD → KRW

for budgeting rather than converting CAD into USD first.

UK Travelers

UK visitors should monitor:

GBP → KRW

and compare the actual rate provided by their bank or exchange provider.

European Travelers

Patients using euros should monitor:

EUR → KRW

and account for any card or exchange fees.

Japanese Travelers

Japanese visitors should compare:

JPY → KRW

when estimating their treatment and travel costs.

How to Get a Better Exchange Rate

Compare the Final Amount You Receive

Do not compare exchange rates based only on the advertised number.

Instead, ask:

"How many Korean won will I receive for this amount of foreign currency after all fees?"

This gives you a more realistic comparison.

Compare Multiple Providers

Before exchanging a large amount, compare:

• Airport exchange counter
• Bank
• Licensed exchange office
• Card payment
• ATM withdrawal

The best option can vary depending on your currency and transaction size.

Avoid Excessive Small Transactions

If every transaction includes a fixed fee, exchanging or withdrawing money repeatedly can increase your total cost.

Plan your cash needs in advance where practical.

Currency Exchange Apps and Online Tools

Use an Exchange Rate Calculator

Before traveling, use a reliable currency converter to understand approximate values.

For example, if you see:

₩800,000

you can quickly estimate its value in your home currency.

Remember that online mid-market rates are often different from the rate you actually receive from a bank, card network, ATM, or exchange office.

Check the Rate on the Day of Payment

For major medical expenses, check the exchange rate close to the payment date.

The rate can change between the time you research a treatment and the day you actually pay.

Currency Tips for International Patients

Keep Some KRW on Arrival

Having Korean won immediately after landing can be useful for transportation and small expenses.

Use a Backup Payment Method

Carry at least two ways to access money.

For example:

• Primary credit card
• Backup debit card
• Small amount of cash

Do not keep every payment method in the same wallet.

Notify Your Bank

Some banks may automatically flag unusual overseas transactions.

Check your bank's international travel policy before departure.

Keep Treatment Payment Records

For expensive procedures, keep:

• Clinic invoices
• Receipts
• Card transaction records
• Deposit confirmations
• Refund documentation

These records can be useful for budgeting and resolving payment questions.

Common Currency Exchange Mistakes

Exchanging Your Entire Budget at the Airport

Airport exchange counters are convenient but may not always provide the most competitive rate.

Ignoring Foreign Transaction Fees

A card with an unfavorable foreign transaction fee can become expensive when used for large medical payments.

Accepting DCC Without Checking

Always understand whether a card terminal is charging you in KRW or your home currency.

Carrying Too Much Cash

Large amounts of cash create unnecessary security risks.

Forgetting Exchange Rate Fluctuations

The exchange rate you see today may not be the rate available when you pay for treatment next week.

Not Separating Treatment Money

Keep your medical budget separate from everyday spending so that shopping and sightseeing do not reduce the funds available for treatment.

Sample Currency Budget for a 7-Day Medical Trip

Medical Treatment

Suppose your treatment budget is:

₩3,000,000

At the illustrative rate of ₩1,438.39 per US$1:

₩3,000,000 ≈ US$2,086

Accommodation

If your hotel costs:

₩150,000 per night

for seven nights:

₩1,050,000

or approximately US$730 at the same illustrative rate.

Food

A moderate food budget of:

₩50,000 per day

for seven days would be:

₩350,000

or approximately US$243.

Transportation and Miscellaneous Expenses

You might allocate:

₩300,000–₩500,000

for airport transportation, local transportation, cafés, small purchases, and unexpected expenses.

This example demonstrates why currency conversion should be considered across the entire trip rather than only for the medical procedure.

Should Medical Tourists Exchange Money Before Arriving in Korea?

A Small Amount Can Be Helpful

Having some Korean won before departure can provide peace of mind.

However, you do not necessarily need to exchange your entire travel budget before arriving.

A balanced approach is:

Small amount before departure + additional KRW in Korea + international card

This provides flexibility.

Can You Use U.S. Dollars in Korea?

KRW Is the Standard Payment Currency

Although some businesses in tourist-heavy areas may be familiar with foreign currencies, you should not expect to pay for everyday purchases or medical treatment directly in U.S. dollars.

Use Korean won or a suitable international payment card.

For medical treatment, confirm the clinic's accepted payment methods and currency before your appointment.

Frequently Asked Questions

What currency is used in Korea?

South Korea uses the Korean won (KRW), represented by the symbol ₩.

Where is the best place to exchange money in Korea?

There is no single exchange location that is always the best. Compare the final amount received from licensed exchange offices, banks, airport counters, and other legitimate providers.

Should I exchange money at Incheon Airport?

Exchanging a small amount at Incheon Airport can be convenient for immediate expenses. For larger amounts, compare rates elsewhere before exchanging all your money.

Is it better to use cash or a card in Korea?

Both can be useful. Cards are convenient for many major purchases, while Korean won is useful for smaller transactions and as a backup.

Should I pay medical treatment in Korean won?

If your clinic quotes the treatment price in KRW, understand the exact KRW amount and ask about accepted payment methods. Paying in KRW can make the local treatment price easier to compare.

Do Korean clinics accept international credit cards?

Many clinics serving international patients accept major international cards, but policies vary. Confirm accepted cards, fees, deposits, and refund procedures directly with your clinic.

How much cash should I bring to Korea for a medical trip?

For everyday expenses, ₩100,000–₩500,000 can provide a useful cash reserve depending on trip length and spending habits. You generally do not need to carry your entire medical treatment budget as physical cash.

Can I withdraw Korean won from an ATM?

Yes, international travelers can use certain Korean ATMs with supported foreign cards. Fees and availability vary, so check your bank and the ATM before making a withdrawal.

What is dynamic currency conversion?

Dynamic currency conversion, or DCC, allows a card transaction to be converted into your home currency at the point of purchase. The exchange rate may include a markup, so compare the offered conversion with your card's normal foreign-currency terms.

Should I exchange all my money before going to Korea?

Usually, there is no need to exchange your entire trip budget in advance. A combination of some Korean cash, an international card, and a backup payment method is often more flexible.

Conclusion

Currency exchange should be included in every international patient's Korea medical tourism budget. The Korean won is the standard currency, and understanding KRW values can make it easier to compare treatment prices, hotel costs, transportation, food, and other expenses.

For most medical tourists, carrying a reasonable amount of Korean cash while keeping the majority of their funds accessible through suitable international cards can provide a good balance of convenience and security. Before exchanging a large amount, compare the actual amount of KRW you will receive, not simply the advertised exchange rate.

Exchange rates can also change significantly enough to affect expensive medical treatments. As an illustrative example, a rate of ₩1,438.39 per US$1 means that a ₩5,000,000 treatment is mathematically equivalent to approximately US$3,476 before any bank, card, or exchange fees. The actual amount charged to your account can differ.

For international patients, the smartest approach is to plan your treatment budget in KRW first, then calculate its approximate value in your home currency. Confirm your clinic's payment policy, check your bank's foreign transaction fees, keep some Korean won available for daily expenses, and maintain a backup payment method.

With a little preparation, currency exchange does not need to be complicated. A clear understanding of KRW, exchange rates, card fees, ATM costs, and cash requirements can help you manage your Korea medical trip more confidently and avoid unnecessary financial surprises.
