International School Fees in Bangkok 2026: Tuition Bands & Extras

Bangkok’s international school fees look friendlier than Singapore or Hong Kong on a first glance — until you add entrance fees, campus funds, bus, and lunch. This is the fee layer for 2026: planning bands in THB from live Smart in Asia profiles, what’s usually excluded, and how to budget the real first year. Shortlist on the Bangkok location directory, and use the Bangkok 2026 fees, waitlists & best fits longform for curriculum and timing context.

What “tuition” usually covers (and what it doesn’t)

Published annual tuition is the recurring academic fee for a year group. It typically excludes application/assessment fees, non-refundable entrance or registration fees, campus development funds (refundable or annual), bus, lunch, uniforms, trips, and exam fees in IGCSE/IB years. Ask HR whether your education allowance covers entrance fees and transport — many packages fund tuition only.

Sample 2026 planning bands (THB — verify with admissions)

Figures below are from live Smart in Asia school profiles (updated Oct 2025). Currency is THB. Always confirm the school’s current fee schedule before you budget.

• NIST International School (full IB): preschool ฿628,200 → elementary ฿842,800 → middle ฿923,700 → high ฿1,094,500; application ฿6,000.
• Bangkok Patana School (British → IB Diploma): preschool ฿495,000 → elementary ฿720,000 → middle ฿810,000 → high ฿975,000; application ฿4,000.
• Harrow International School Bangkok (British IGCSE/A-Level): preschool ฿487,500 → elementary ฿671,900 → middle ฿782,200 → high ฿982,400; application ฿5,000.
• International School Bangkok (ISB) (American + AP/IB options): preschool ฿640,000 → elementary ฿985,000 → middle ฿1,104,000 → high ฿1,162,000; application ฿4,700.

Across the wider Bangkok directory, value-tier campuses can start in the low-to-mid ฿100,000s–฿200,000s, while ultra-premium secondary years sit past ฿1 million. Match year group to year group — a preschool line next to Grade 11 is not a market comparison.

Extras that break first-year budgets

• Application fees (often ฿4,000–฿6,000 on these profiles)
• Entrance / registration / campus development fees — ask refundable vs non-refundable in writing
• Bus, lunch, uniforms, activities, and exam fees

A practical buffer: plan 20–30% above published annual tuition for year one, then replace the buffer with the school’s own THB schedule once you have an offer. Always verify every line with admissions.

Final thoughts

Bangkok rewards families who budget the real first year in THB — tuition plus entrance costs and logistics — not the brochure number alone. Open three to five profiles on the Bangkok directory, cross-check waitlists in the 2026 longform, and confirm every figure with admissions before you lock housing or an HR package.
