Introduction
Public transportation is one of the first things foreigners notice in Seoul.
Subways and buses are clean, reliable, and easy to use, even if you do not speak Korean.
Still, one question comes up again and again.
How much does public transportation actually cost in Seoul?
This guide explains the real fares, how transfers work, and what foreigners should expect when moving around the city.
Basic Seoul Public Transportation Costs (Subway & Bus)
Seoul uses a distance-based fare system.
This means you do not pay per line or per transfer. You pay based on how far you travel.
Most visitors use a T-money card for daily transportation, especially when riding buses and subways frequently. If you are not familiar with how the card works, understanding the basics first will make the fare system much easier to follow.
With a T-money card:
- Short trips start at a low base fare
- Longer trips add small distance-based charges automatically
Cash payments are possible, but they cost more and do not allow transfers.
Current Seoul Public Transportation Fares (2025–2026)
| Transportation | Card Fare (T-money) | Cash / Single Ticket | What This Means |
|---|---|---|---|
| Subway | ₩1,550 | ₩1,650 | Base fare for short trips |
| City Bus | ₩1,550 | ₩1,550 | Standard city buses |
| Night Bus | ₩2,500 | ₩2,500 | Late-night buses only |
| Airport Railroad (AREX – all-stop) | about ₩4,000–₩5,000 | — | Incheon Airport to Seoul |
For longer trips or airport routes, some travelers use a transport fare simulator to check expected costs in advance.
How Transfers Between Bus and Subway Really Work
Transfers are one of the biggest reasons public transportation stays affordable in Seoul.
When you transfer between:
- subway to bus
- bus to subway
- bus to bus
within the allowed time, you do not pay a new base fare.
Instead, the system calculates only the additional distance.
This happens automatically when you tap your card in and out.
Forgetting to tap out can result in being charged the maximum fare, so always tap when exiting.
Getting From Incheon Airport to Seoul
If you are arriving at Incheon International Airport, transportation costs depend on how you enter the city.
The most common options are:
- Airport Railroad (AREX)
- Airport limousine buses
- Taxis
The all-stop AREX train is the most affordable and predictable choice for most travelers.
Airport buses cost more but are convenient if your hotel is far from a subway station.
Many travelers also arrange their mobile connection immediately after landing, which makes checking routes and fares much easier during the trip into Seoul.
Do Public Transportation Fares Change at Night?
Yes, but only in specific cases.
Late-night buses, usually marked with an “N,” cost more than regular buses.
Subway fares do not change, but most subway lines stop running around midnight.
After that, travelers rely on night buses or taxis, which can increase daily transportation costs.
Estimating Longer or More Complex Trips
Short trips inside central Seoul are usually inexpensive.
However, longer rides or multiple transfers across districts can add up.
When planning day trips, airport travel, or unfamiliar routes, it helps to estimate the fare in advance. Some travelers use a transport fare simulator to check expected costs before leaving.
This is especially useful if you are trying to compare public transportation with taxis or private transfers.
Is Seoul Public Transportation Cheap Compared to Other Cities?
Compared to cities like New York, London, or Tokyo, Seoul is considered affordable.
Foreigners benefit from:
- Low base fares
- Free transfers
- Frequent service without zone confusion
For most visitors and residents, transportation remains one of the lowest daily expenses unless taxis are used often.
Final Tips for Foreigners Using Public Transportation
- Always tap in and tap out
- Use a T-money card instead of cash
- Transfers save money when done correctly
- Keep a small balance on your card at all times
Once you understand these basics, getting around Seoul becomes simple and stress-free.
