Calculation of 2026 subway transfer fares: base fare, distance addition, metropolitan bus basis

Please organize “destination, direction, and payment method” separately before transferring.

Before departure, check whether the bus you are riding is a regular city bus or a metropolitan/seat/direct bus. Even for the same subway destination, the basic distance standards and applicable fares may vary if the type of bus is different, so you need to get into the habit of checking the type of transportation in the route search.

Transferring isn't just about matching the route number. You must check at once the station you will get off at, the direction of the next train, the route you will take within the station, and whether you can continue to use the same transportation card. Especially if you have an appointment or are traveling on the last train, it is better to not just look at one recommended route in the map app, but also compare routes with different numbers of transfers and walking sections.

Fares and transfer rules should be read as actual travel conditions

According to the official information, the basic fare is applied for general integrated transfers up to 10 km, and 100 won is added for every 5 km beyond 10 km. When Seoul metropolitan area, Gyeonggi area bus, direct route, Incheon area bus, and metropolitan bus are included, the standard is provided up to 30km, and the higher basic fare is applied among the means used.

The Seoul Transportation Corporation's fare guide also presents conditions such as use of transportation card, disembarkation tag, and authorized time for subway and bus transfers. Since the base fare and distance surcharge may vary depending on the route used and the type of bus, use this article as a guide to understanding the principle, and check the actual payment amount with the official information on the departure date and card usage history.

At large transfer stations, double check your directions.

When comparing fares, search from departure point to destination at once to see the order of buses and subways, number of transfers, and total travel time. If you separate out some sections and add the basic fares for each, it may differ from the actual calculation of the integrated distance proportional system, so for routes you take frequently, it is recommended to check the results with your card usage history.

Immediately after getting off the train, rather than running with the flow of people, it is easier to get out of the way and check the line number, color, next station, and destination in order. At stations with long transfer corridors, you should not only look at the platform arrival time, but also include waiting time for the next train and walking time to the destination exit in your schedule.

Typical mistakes that ruin transfer discounts and travel time

There are many mistakes in calculating routes that include intercity buses in the same way as regular city buses, or interpreting the 10km/30km standard as an individual's walking distance. Since this standard is a condition of the usage distance of the integrated fare, do not arbitrarily determine the exact final price, but give priority to the official fare information and same-day route inquiry.

If the fare turns out to be higher than expected or you catch a train in the opposite direction, don't just rely on memory; check your card usage details, boarding/disembarking times, and current station. On days with construction, events, congestion, or train delays, your usual shortest route may not be the most convenient, so it's a good idea to save alternative transfer stations or other modes of transportation in advance.

Practical methods to apply to the day’s schedule

If you repeat the same route, such as commuting to work or school, estimate your monthly transportation costs by recording the actual amount used per week. If you can change your route, you can reduce costs and fatigue by comparing the number of transfers, whether or not a metropolitan bus is included, walking distance, and congestion, rather than just looking at the quickest route by a few minutes.

If you need to transfer multiple times, it is safer to check only the next section after getting off each time, rather than trying to memorize everything on the first section. Since your phone's battery may be low or communication may be unstable, keep a note or capture of the departure station, transfer station, arrival station, destination address, and alternative means of transportation when the last train is close.

Pre-departure checklist

If you check the items below first, you can reduce time and fare variables in the transfer process. Actual train operation, station construction, elevator equipment status, and fares may change, so give priority to the station electronic display board and official information from the operating organization just before departure.

• Check whether the bus is regular, seat, direct, or wide area.
• Search the entire path at once
• Check the possibility of high base fares and distance surcharges
• Observe transportation card, get-off tag, and recognition time conditions
• Check the final amount through the official information and card details on the day.
