The Seoul fee landscape
Seoul hosts about 40 international schools serving expat communities concentrated around US military, embassy and corporate sectors. SFS (Seoul Foreign School) is the long-established premium British/American hybrid; SIS (Seoul International School) and KIS Seoul (Korea International School) deliver American-curriculum IB Diploma. Yongsan International School and BSS (British School Seoul) round out the premium tier. Premium fees sit at KRW 38-46 million per year.
Critical regulatory note: most Seoul international schools restrict admissions to families where at least one parent holds non-Korean nationality, or to children with significant overseas residency. Korean nationals face restrictions on attending pure international schools. Several "international" schools (e.g., certain bilingual schools) accept Korean nationals.

The hidden extras
Total cost-of-place adds 10-15% to headline fees. Largest line items: registration/enrolment (KRW 1.5M-4M one-time), school bus (KRW 4M-7M. Seoul distances make this near-essential), uniform (KRW 800,000-1.8M), iPad/laptop programmes (KRW 1.5M-3M), exam entries (KRW 1.2M-2.5M in IGCSE/IB years), trips (KRW 2M-5M), lunch (KRW 2.5M-4.5M).
Year-on-year fee inflation
Seoul school fees rose 4.0% on average across 2025-26, slightly above Korean CPI of 2.5%. Premium schools tracked 4.0-4.5%; mid-tier 3.5-4.0%. Korean won has been relatively stable against USD over the past two years, so USD-paid families experienced similar fee increases in dollar terms.
The Korean nationality question
Most Seoul international schools (SFS, SIS, KIS Seoul, YISS, BSS) restrict admissions to families with at least one non-Korean passport-holder parent OR to children with at least three years of foreign residency. This is enforced strictly. Korean nationals seeking international curriculum education typically attend schools that explicitly accept Korean nationals (some bilingual schools, certain Christian-foundation schools) or international branch campuses overseas (Jeju International School Hub).
Seoul vs. Tokyo vs. Hong Kong
A premium IB Diploma place at SFS or KIS Seoul runs KRW 42-46 million (USD 30,000-33,000) per year. The Tokyo equivalent at K International or ASIJ runs JPY 3.2-3.5M (USD 21,000-23,000). Tokyo is currently meaningfully cheaper in USD due to yen weakness. The Hong Kong equivalent at HKIS or GSIS runs HKD 280,000-310,000 (USD 36,000-39,500). Seoul sits between Tokyo (cheaper) and Hong Kong (more expensive).
Sibling discounts
Most Seoul international schools offer 5-10% sibling discounts. SFS and several premium schools offer modest sibling discounts. See our sibling discount table.
Currency exposure
KRW-denominated. USD-paid families have moderate currency risk; the Korean won has been moderately stable against USD recently.
