Is the Subway Expensive in Korea? An In-Depth Look at Seoul’s Public Transit Costs

I remember Sarah, a buddy from back home, landing in Incheon, bright-eyed and buzzing with excitement for her first trip to Seoul. She’d heard all the hype about Korea’s super-efficient public transport, but as she stood at the subway station contemplating her first ride, a thought nagged at her: “Is the subway expensive in Korea? Am I about to drop a fortune just getting around?” It’s a common worry, especially when you’re used to, say, the sometimes wallet-draining fares of New York City or London’s Tube. But let me tell you straight, and clear as a bell: No, the Korean subway, especially in bustling Seoul, is remarkably affordable, particularly when you weigh its incredible efficiency, cleanliness, and extensive reach against its cost.

Sarah, like many first-timers, was pleasantly surprised. What she quickly discovered, and what you’re about to learn, is that Korea offers an exceptional public transit experience that is not only a breeze to navigate but also incredibly light on your pocket. It’s a far cry from the sticker shock you might encounter in many Western metropolises. So, if you’re wondering if you’ll be shelling out big bucks to zip around the Land of the Morning Calm, you can breathe a sigh of relief. Let’s dive deep into why this essential mode of transport is such a bargain and how you can make the most of it.

Understanding the Korean Subway Fare Structure: More Than Just a Flat Rate

The beauty of the Korean subway system, particularly in major cities like Seoul, Busan, and Daegu, lies not just in its expansive network but also in its well-structured and transparent fare system. It’s not a flat rate for any distance, which might feel different if you’re used to systems that charge the same no matter if you go one stop or ten. Instead, it operates on a base fare plus a distance-based addition, which is actually quite fair and prevents short-distance riders from subsidizing the long-haul commuters too heavily.

The Base Fare Explained: Your Starting Point

Every journey on the Korean subway begins with a base fare. As of the most recent adjustments, which took effect in late 2023/early 2024, the standard base fare for an adult using a rechargeable transit card (like a T-Money card) is generally around 1,400 to 1,550 Korean Won (KRW). For context, at current exchange rates, that’s roughly equivalent to about $1.00 to $1.15 USD. Now, let’s pause for a second: for a system that can take you across a sprawling city like Seoul, this initial cost is, frankly, astounding. Compare that to a single ride on the New York City subway, which clocks in at $2.90, or London’s Tube, which can easily be £2.80 (around $3.50 USD) for a short hop, and you immediately see the incredible value. This base fare covers your journey for the first 10 kilometers (about 6.2 miles).

Distance-Based Additions: When Fares Nudge Up

Once you travel beyond that initial 10-kilometer threshold, the fare incrementally increases. It’s not a dramatic jump, mind you; we’re talking about small additions. Typically, an extra 100 KRW (about $0.07-0.08 USD) is added for every subsequent 5 kilometers (approx. 3.1 miles) traveled, up to 50 kilometers. Beyond 50 kilometers, the increment changes to 100 KRW for every 8 kilometers. This system ensures that even a cross-city trek still remains remarkably inexpensive. For instance, a ride spanning 20 kilometers might cost you around 1,600 KRW, still well under $1.50 USD. This tiered approach ensures you’re paying for what you use, but never an exorbitant amount.

The Genius of Transfer Benefits: Unlocking Even More Savings

Perhaps one of the most brilliant aspects of Korea’s public transportation system is its integrated transfer policy. This is where you really start to feel like you’re getting a steal. When you use a T-Money card or a similar transit card, you can transfer between subway lines, or even between the subway and local buses, without paying a new base fare each time. You get up to four free transfers within a specific time window (usually 30-45 minutes, with the window extending to an hour during late-night hours). The system simply calculates the total distance traveled across all legs of your journey and applies the distance-based fare structure accordingly. This means a complex journey involving multiple subway lines and even a bus connection often costs you only slightly more than a single, direct subway ride, if at all. For Sarah, coming from a city where each transfer might mean a new fare, this was a game-changer, making her daily explorations incredibly budget-friendly.

Recent Fare Adjustments: A Slight Nudge, Still a Bargain

It’s true that Korea, like any nation, experiences inflation and rising operational costs. In October 2023, Seoul saw its first subway fare hike in eight years, with the base fare for transit cards increasing by 150 KRW. A further increase of 150 KRW is planned for the second half of 2024. While any increase might initially sound concerning, these adjustments have been modest, bringing the current base fare for T-Money users to 1,400 KRW and cash users to 1,550 KRW. Even with these slight nudges, the system remains incredibly competitive globally, and the value proposition hasn’t diminished one bit. It’s still significantly cheaper than comparable systems in many developed countries, maintaining its status as an affordable gem.

The T-Money Card: Your Best Friend for Korean Transit

If you’re going to ride the Korean subway, or any public transit in Korea for that matter, the T-Money card is absolutely indispensable. Forget fumbling for change or dealing with single-use tickets that often cost more; this little plastic card is your golden ticket to convenience and savings.

What It Is and Why You Need It

A T-Money card is a rechargeable smart card used for public transportation fares and even small purchases at convenience stores, vending machines, and some taxis. It’s the dominant transit card in Seoul and many other parts of Korea. Why do you need it? Simple: it offers a discount on the base fare (cash fares are almost always higher), allows for seamless transfers between different modes of transport, and saves you time at ticket machines. Plus, you’ll look like a local, zipping through the turnstiles with a quick tap.

Where to Buy and Recharge Your T-Money Card

Getting your hands on a T-Money card is incredibly easy. You can purchase one for a small fee (usually 2,500 – 4,000 KRW, non-refundable) at:

• Convenience Stores: Look for 7-Eleven, GS25, CU, Ministop, and E-mart24 outlets. These are practically on every corner. Just ask the clerk for a “T-Money card.”
• Subway Stations: There are often vending machines and customer service offices within subway stations where you can buy and load a card.

Recharging is just as simple:

• Subway Station Vending Machines: These machines are multi-lingual and easy to use. You can load cash onto your card.
• Convenience Stores: Hand your card and the cash you want to load to the clerk. They’ll handle it in seconds.

I always recommend loading at least 10,000 to 20,000 KRW (about $7-15 USD) to start, depending on the length of your stay and how much you plan to use public transport. You can always top it up later. Any unused balance (minus a small service fee) can be refunded at convenience stores for amounts under 20,000 KRW, or at larger T-Money service centers for higher amounts, before you leave the country.

Benefits of Using a T-Money Card

• Fare Discounts: As mentioned, T-Money users enjoy a slightly lower base fare compared to cash payments. Every little bit helps, right?
• Seamless Transfers: This is the big one. It enables the integrated transfer system, saving you a bundle on multi-leg journeys.
• Convenience: No need for exact change or waiting in line for single-use tickets. Just tap and go.
• Wider Acceptance: Besides the subway and buses, T-Money can be used for taxis, at certain vending machines, and convenience stores for small purchases, making it a truly versatile tool.
• Children and Youth Fares: If traveling with kids, specific T-Money cards can be registered for child (ages 6-12) or youth (ages 13-18) fares, which are significantly discounted. Remember to register them at a convenience store with a valid ID (passport for tourists) to get these reduced rates.

While T-Money is the most prevalent, you might also come across Cashbee cards, especially in areas like Busan. They function almost identically to T-Money cards and are generally interchangeable for public transport purposes. So, whichever you grab, you’re usually good to go.

Comparing Costs: Korean Subway vs. Other Major Cities (US Perspective)

To truly grasp just how affordable the Korean subway is, it helps to put it into perspective against other global giants. For an American traveler, the contrast can be quite stark.

Let’s take a look at some approximate base fares for adult single rides (using a transit card where applicable) in major cities, converted to USD for an easier comparison (note: exchange rates fluctuate, these are estimates):

As you can clearly see from the table, Seoul stands out as an exceptionally budget-friendly option. While Tokyo’s base fare might seem comparable, the complexity of its multi-company railway system often means that journeys involving transfers between different operators can quickly add up, unlike Seoul’s fully integrated and seamless experience. New York City, London, Paris, and Berlin all command significantly higher fares for even a basic ride.

My personal take? The Korean subway offers an unparalleled blend of cost-effectiveness and quality. You’re not just paying less; you’re often getting a superior experience in terms of cleanliness, modernity, and reliability compared to many of its global counterparts. For anyone traveling on a budget, or simply someone who appreciates great value, Korea’s subway system is truly a godsend.

Factors Influencing Your Subway Cost in Korea

While the overall message is that the Korean subway is affordable, a few factors can subtly influence your total outlay. Understanding these can help you better manage your transit budget.

Commuting vs. Tourist Use: Different Travel Patterns

For a local commuter, daily costs can add up, but they often benefit from monthly passes (like the Climate Card, which offers unlimited rides for a set period within Seoul for a flat fee). As a tourist, your usage pattern will likely be different. You might take fewer, but potentially longer, rides as you explore different districts, or have periods of intense travel followed by days of walking. The distance-based fare structure means longer tourist excursions will naturally cost a bit more per trip than a local’s short daily commute, but the total daily expenditure for tourists still tends to be very low compared to other major cities’ tourist transit costs.

Type of Pass/Card: T-Money is King

As repeatedly emphasized, using a T-Money card is the most cost-effective method. Single-use tickets purchased from vending machines are typically 100-150 KRW more expensive than T-Money fares, *plus* they usually require a 500 KRW deposit which you get back when you return the card. While you *can* use cash to buy single-use tickets, it’s cumbersome and more expensive in the long run. Stick with the T-Money card; it’s a no-brainer for maximizing savings and convenience.

Distance Traveled: The Primary Cost Driver

This is the most significant factor. A short hop from Gangnam to Sinsa will cost the base fare. A journey from Incheon International Airport all the way across Seoul to, say, Gapyeong (which involves transfers to outer lines), will naturally accrue more distance-based additions. However, even these longer journeys rarely break the bank. For example, a lengthy trip from one end of Seoul to the other might top out at around 2,000-2,500 KRW (about $1.50 – $1.80 USD), which is still incredibly cheap for covering such vast distances.

Airport Travel: A Special Consideration

Traveling to and from Incheon International Airport (ICN) or Gimpo International Airport (GMP) via subway is generally straightforward and affordable. The Airport Railroad Express (AREX) operates two types of services: the All-Stop Train and the Express Train. The All-Stop Train is effectively a part of the regular subway network, allowing T-Money usage and integrated transfers, making it very economical. The Express Train, which goes non-stop between Incheon Airport Terminal 1 & 2 and Seoul Station, is faster but costs more (around 9,500 KRW for a one-way ticket for adults, subject to change) and does not offer transfer benefits with other subway lines. For most budget-conscious travelers, the All-Stop AREX train is the preferred option, as it seamlessly integrates with your T-Money and allows for free transfers to other lines once you reach a connecting station.

Beyond the Base Fare: Maximizing Value with Passes and Integrated Systems

The Korean subway system truly shines in how it helps you maximize value, especially if you’re smart about using its integrated features and specialized passes.

The “Integrated Transit System”: Your Money-Saving Ace

I’ve touched on this, but it bears repeating because it’s genuinely revolutionary. The ability to transfer between subway lines and even local buses within a fixed time frame (usually 30-45 minutes) without incurring a new base fare is a massive money-saver. This means you can create complex routes that combine different modes of transport, covering significant distances, all while being charged as if it were a single, continuous journey based on the total distance. It’s a testament to urban planning and a clear win for the rider. My advice? Always tap your T-Money card when entering and exiting *every* subway station, and when boarding and alighting *every* bus. This ensures the system accurately calculates your total journey and applies the correct, usually discounted, fare.

Seoul Tourist Passes: Are They Worth It for Subway Use?

For tourists, there are a couple of popular passes designed to offer convenience and potential savings on attractions and transport. However, it’s crucial to assess if they genuinely save you money on subway fares.

• Discover Seoul Pass: This pass offers free entry to numerous attractions and doubles as a T-Money card. While it provides a T-Money function for subway and bus travel, the transit fare portion needs to be separately topped up with money. The value of this pass primarily comes from its attraction benefits. If you plan to visit many of the included attractions, then it’s a fantastic deal; the transit capability is a bonus. If you’re only interested in the subway, a regular T-Money card is more economical.
• Korea Tour Card: Similar to a T-Money card but marketed towards tourists, it offers discounts at certain shops and attractions. Like the Discover Seoul Pass, it needs to be topped up for transit use. It’s essentially a T-Money card with a few extra perks, so it functions just as well for subway fares.
• M-Pass (Metropolitan Pass): This pass, designed for foreign tourists, offers unlimited rides on the Seoul Metropolitan Subway and public buses within Seoul for a chosen duration (1, 2, 3, 5, or 7 days). It also functions as a T-Money card for other purchases, provided you top it up.
  • Is it worth it? This depends entirely on your travel intensity. If you anticipate taking 10-20 rides *per day* on the subway and bus, then an M-Pass could potentially offer savings. However, for the average tourist taking 3-5 rides daily, the standard T-Money card with its distance-based and transfer-friendly fares will almost certainly be cheaper. The Seoul subway is so affordable that even frequent use rarely justifies the upfront cost of an M-Pass for most visitors. Always do the math based on your planned itinerary!

Long-Term Passes for Residents (e.g., Climate Card)

While not directly applicable to most tourists, it’s worth noting that for long-term residents or those staying for extended periods, Seoul has introduced initiatives like the “Climate Card.” This allows for unlimited subway and bus rides within Seoul for a monthly fee. It’s a fantastic initiative for local commuters aimed at promoting public transport and reducing carbon emissions, further demonstrating the city’s commitment to accessible and efficient public transit. This isn’t a tourist product, but it showcases the depth of options available within the system.

The Unbeatable Value: Why Korea’s Subway System Shines

Beyond the raw numbers, the true value of the Korean subway extends to the overall experience it provides. It’s not just cheap; it’s genuinely excellent.

Efficiency and Punctuality: Time is Money!

The Korean subway system is legendary for its punctuality. Trains arrive and depart on schedule, with minimal delays. This level of reliability means you can plan your day with confidence, knowing you won’t be stuck waiting or late for appointments. For a traveler, this translates directly into saving time, and as we all know, time is a precious commodity, especially on vacation.

Cleanliness and Safety: A Comfortable Experience

Step into a Korean subway station or car, and you’ll immediately notice the impeccable cleanliness. Stations are well-maintained, and trains are spotless. It’s a stark contrast to some of the grittier subway systems around the world. Moreover, safety is a top priority. Stations are well-lit, often staffed, and have clear emergency protocols. As a solo traveler, or just someone who values a secure environment, the sense of safety on the Korean subway is truly reassuring, even late at night.

Accessibility and Reach: Getting Almost Anywhere

Seoul’s subway network is a marvel of urban engineering, boasting over 20 lines that spiderweb across the city and beyond, reaching neighboring Gyeonggi Province and Incheon. Whether you’re trying to get to a historical palace, a bustling shopping district, or a quiet residential area, there’s almost certainly a subway station within walking distance. This extensive reach means you rarely need to hail a taxi, further reducing your overall transportation costs and making exploration a breeze.

Amenities: Thoughtful Touches for a Better Ride

The Korean subway isn’t just about getting from A to B; it’s about doing so comfortably. Many newer trains boast heated seats in winter, and all offer robust air conditioning in summer. You’ll often find free public Wi-Fi available on trains and within stations, allowing you to stay connected. Furthermore, stations are equipped with clean public restrooms, vending machines for drinks and snacks, and often small shops or even underground malls, transforming them into mini-destinations themselves. These thoughtful amenities enhance the travel experience, adding value far beyond the ticket price.

Cultural Aspects: Etiquette and Observation

Riding the subway in Korea offers a fascinating glimpse into local life. Observe the orderly queues, the quiet respect among passengers, and the ubiquitous smartphone usage. Special priority seating for the elderly, pregnant women, and those with disabilities is strictly observed. It’s an efficient, respectful, and surprisingly serene environment, a public space that functions with remarkable harmony. This cultural immersion is an added, priceless bonus to your affordable ride.

Practical Tips for Riding the Korean Subway

Ready to jump on? Here are some practical tips to make your Korean subway experience as smooth and cost-effective as possible.

• Get a T-Money Card ASAP: This should be your first priority after landing. Purchase and load it at the airport or any convenience store.
• Download a Subway App: Apps like “KakaoMetro” or “Subway Korea” (available on both iOS and Android) are indispensable. They provide real-time train schedules, detailed route planning (including transfer points and estimated journey times), and fare calculations. They’re usually available in English and make navigating the complex network incredibly easy.
• Mind the Transfer Window: Remember that 30-45 minute window for free transfers. If you dilly-dally too long between tapping out of one mode and tapping into another, you might incur a new base fare.
• Always Tap In and Out: This is critical. You must tap your T-Money card on the sensor when entering the station *and* when exiting. Failing to tap out can result in penalty fares or the card being temporarily blocked. If you’re transferring, tap out of the subway, and then tap in when boarding the bus (and tap out when alighting the bus).
• Know Your Destination’s Station Number: Many stations are numbered, which can be helpful if you’re not familiar with the Korean names. The apps will show these.
• Avoid Rush Hour if Possible: While efficient, the Seoul subway during peak morning (7:30 AM – 9:30 AM) and evening (5:30 PM – 7:30 PM) rush hours can be incredibly crowded, especially on major lines. If you’re not in a hurry, traveling outside these times will offer a more comfortable experience.
• Listen for Announcements: Most major line trains and stations will have announcements in Korean, English, Japanese, and Chinese, making it easy for international travelers to keep track of their journey.
• Stay Hydrated and Grab a Snack: With convenience stores in many stations, it’s easy to grab a drink or a quick bite for your journey.

Is it Really *Never* Expensive? Specific Scenarios

While the overwhelming answer is that the Korean subway is affordable, it’s worth addressing specific scenarios where costs might differ or where alternatives are more appropriate.

Long-Distance Inter-City Travel: KORAIL vs. Subway for Regional Hops

The Korean subway system is primarily for urban and suburban travel. For true long-distance inter-city travel, like going from Seoul to Busan or Gyeongju, you’ll be looking at KORAIL (Korea Railroad) services, such as the KTX high-speed rail. These services are separate from the subway and, naturally, significantly more expensive, though still competitive with other high-speed rail systems globally. For example, a KTX ticket from Seoul to Busan can range from 59,800 KRW to 83,700 KRW (approx. $45-$62 USD), depending on the class and train. So, while your subway within Seoul is cheap, don’t confuse that with the cost of zipping across the entire country.

Airport Express (AREX) Specifics

As mentioned earlier, the AREX Express Train (non-stop between Incheon Airport and Seoul Station) is more expensive than the All-Stop train, which is essentially part of the regular subway network. If speed is paramount and you’re willing to pay a premium (around $7-8 USD), the Express Train is an option. However, for most, the All-Stop train provides excellent value and convenience, especially with the seamless transfer benefits of the T-Money card. It’s a trade-off between a few extra minutes of travel time and significant cost savings.

Late-Night Surcharges (Rare for Subway, More for Taxis)

Unlike some taxi services in Korea that implement late-night surcharges (typically from midnight or 11 PM), the subway itself does not have a “late-night surcharge” on its fares. However, the subway system generally ceases operation around midnight or 1 AM, depending on the line and day of the week. If you find yourself out past these hours, you’ll need to rely on late-night buses or taxis, which *will* be more expensive than the subway, especially taxis with their surge pricing. So, while the subway itself doesn’t get pricier, your alternatives do if you miss the last train.

Frequently Asked Questions (FAQs) About Korea’s Subway Costs

How much does a T-Money card cost initially?

The initial purchase cost of a T-Money card itself is usually between 2,500 KRW and 4,000 KRW (approximately $1.80 to $3.00 USD), depending on where you buy it (convenience store vs. subway station vending machine) and if it has a special design. This is a one-time, non-refundable cost for the card itself. You then need to load money onto it separately to pay for your rides. So, for example, you might pay 4,000 KRW for the card and then load an additional 10,000 KRW, making your initial outlay 14,000 KRW.

It’s important to remember that this initial card cost is for the physical card, similar to buying a MetroCard in NYC or an Oyster card in London. It’s not part of your transit balance. Once you have the card, you can continue to recharge it as needed throughout your stay and even keep it for future visits, as T-Money cards generally don’t expire for regular use.

Can I use a credit card on the Korean subway?

Generally, no, you cannot directly use a foreign credit card to tap and pay for individual subway rides at the turnstiles. The primary methods for fare payment are T-Money cards (or similar transit cards) or single-use paper tickets. While you can use a credit card to purchase or recharge a T-Money card at some subway station vending machines or larger customer service centers, convenience stores typically only accept cash for T-Money recharges. It’s always a good idea to have some Korean Won cash on hand for these purposes.

Some Korean domestic credit cards have a T-Money function built in, allowing locals to tap and pay. However, this functionality is usually not extended to international credit cards or debit cards. Therefore, for tourists, the T-Money card loaded with cash remains the most reliable and convenient way to pay for your subway journeys.

Are there student discounts for the subway in Korea?

Yes, there are discounted fares for children and youth on the Korean subway system, but specific conditions apply. Children (ages 6-12) and Youth (ages 13-18) receive significantly reduced fares. To avail of these discounts, you need to purchase a specific Child or Youth T-Money card and have it registered. This registration usually involves presenting a valid ID (like a passport for foreign visitors) at a convenience store or a subway station customer service center.

Without registration, a Child or Youth T-Money card will default to charging adult fares. For university students or those above 18, generally, adult fares apply unless they are enrolled in a specific Korean educational program that qualifies for a local student transit benefit, which is uncommon for short-term visitors. Always ensure your card is properly registered for the correct age group to benefit from these savings.

Is the subway cheaper than buses in Korea?

The cost of the subway and buses in Korea is generally quite comparable, especially when using a T-Money card due to the integrated transfer system. A base fare for a local bus is often similar to the subway base fare (around 1,200 KRW to 1,500 KRW, depending on the city and bus type). The beauty lies in the transfers: if you start your journey on a subway and then transfer to a bus, or vice-versa, within the designated time limit, you’re only charged for the total distance of your entire journey, not a new base fare for each mode of transport.

There are some minor differences: Express buses (Gwangyeok-bus) or intercity buses will naturally cost more. However, for getting around within the city, both the subway and local buses offer excellent value. Many locals will combine both, choosing the subway for longer, faster trips between major points and buses for shorter, more direct routes to specific neighborhoods, all while benefiting from the integrated fare system.

What’s the best way for tourists to pay for the subway?

Without a doubt, the absolute best way for tourists to pay for the subway in Korea is by using a T-Money card. It offers unparalleled convenience and cost savings compared to any other method. As highlighted earlier, it provides discounted fares, allows for free transfers between different modes of public transport, and saves you the hassle of purchasing single-use tickets for every journey.

Purchasing a T-Money card is simple and can be done right at the airport or any major convenience store. Load it with a comfortable amount of cash, and you’re set. It significantly streamlines your travel experience, making it stress-free and economical, allowing you to focus on enjoying the sights and sounds of Korea.

How do transfer discounts work?

The transfer discount system in Korea is a fantastic feature of the public transportation network. When you use a T-Money card (or similar transit card), the system tracks your journey across multiple modes of transport. After tapping out of a subway station, or alighting a bus, you typically have a window of 30 to 45 minutes (longer in late-night hours) to tap into another subway line or board another bus without being charged a new base fare. The system calculates the total distance traveled from your first tap-in to your final tap-out across all transfers.

You’ll only pay the initial base fare plus any distance-based additions for the entire combined journey, rather than paying a separate fare for each segment. This means a trip that might involve one subway, a transfer to another subway line, and then a bus ride, could cost you only slightly more than a single, direct subway journey. It’s crucial to always tap your card both when entering and exiting *each* mode of transport (subway turnstile, bus reader) to ensure the system correctly applies these discounts.

Are there any special passes for unlimited subway travel?

For tourists, the main option for unlimited subway (and bus) travel is the M-Pass (Metropolitan Pass). This pass is specifically designed for foreign visitors and offers unlimited rides on the Seoul Metropolitan Subway and public buses within Seoul for a chosen duration (1, 2, 3, 5, or 7 days). It also functions as a T-Money card, so you can load additional money onto it for use in convenience stores, taxis, or for travel outside the covered zones.

However, whether the M-Pass is truly “worth it” depends heavily on your planned usage. For the average tourist, the base fare of the Korean subway is so low, and the transfer discounts so effective, that most find a regular T-Money card more economical. An M-Pass only starts to make financial sense if you anticipate taking a very high number of rides per day (e.g., 10-20 separate taps) for several consecutive days. Always calculate your estimated daily rides against the cost of the M-Pass before purchasing.

What if I run out of money on my T-Money card mid-trip?

This is a common concern, but thankfully, the Korean subway system has a convenient solution. If you tap out at a subway station and find that your T-Money card has insufficient funds to cover the fare for your completed journey, you can still exit the station. Most subway gates will allow a negative balance of up to approximately 250 KRW (or more on some lines). If the deficit is greater, or if you prefer to top up immediately, there are “fare adjustment machines” (운임부족액 정산기) located near the turnstiles at every exit. You can use these machines to add just enough money to cover the remaining fare or top up your card with a larger amount for future use.

Alternatively, you can go to a nearby convenience store within the station or just outside to recharge your card. It’s a very forgiving system designed to prevent you from being stranded. However, it’s always best practice to periodically check your card balance at a convenience store or subway station vending machine and top it up preemptively to avoid any last-minute hassle.
