How Seoul subway fares are calculated
The Seoul subway system operates on a distance-based fare structure. As of the June 2025 adjustment, the adult base fare starts at ₩1,550 for the first 10 km when using a T-money card. Buying a single-use paper ticket costs ₩100 more, starting at ₩1,650.
If your ride exceeds 10 km, distance-based surcharges apply. For journeys between 10 km and 50 km, an extra ₩100 is charged for every 5 km. For journeys exceeding 50 km, an extra ₩100 is charged for every 8 km. All of these are calculated and billed automatically when you tap out at the exit gate.
Please note that private lines, such as the Shinbundang Line, have separate surcharges (typically between ₩700 and ₩1,000 extra) which are added automatically. Also, single-use tickets require a refundable ₩500 deposit card that must be returned to a refund machine to get your coins back.
Quick answers
What is the 15-minute re-entry rule?
If you accidentally pass through the wrong gate, need to change platforms, or need to use the restroom, you can exit the turnstile and tap back into the same station within 15 minutes for free. This continuous transfer benefit applies to T-money and transit cards, but not single-use tickets.
Is there an early bird discount?
Yes. If you tap your transit card before 6:30 AM on a weekday, a 20% discount is automatically applied to your base subway fare.
Do children or seniors get free rides?
Free rides for seniors over 65 are strictly limited to Korean citizens and registered senior residents holding specific welfare cards. Foreign tourists aged 65 and older must pay the standard adult fare. Children (6-12) and youth (13-18) get discounted card rates of ₩550 and ₩900 respectively.
