International School Fees in Bangkok

The spread

The standout fact about Bangkok's international school market is the spread. The cheapest top-year fee is THB 89,000 at Rising Oaks International School in Watthana; the most expensive is THB 1.24 million at Wellington College's Year 12. That is USD 2,500 to USD 34,700 at THB 1 = 0.028, almost a fourteen-fold range between schools that all describe themselves as international.

Top-year day fee for schools whose published programme reaches at least age 14. USD at indicative mid-2026 rates; the local-currency figure is the verifiable one.

The median top-year fee is THB 550,000 (USD 15,400). Half of all schools price their senior year between THB 342,000 and THB 768,000 (USD 9,600 to USD 21,500). The 90th percentile is THB 998,000 (USD 27,900): most schools sit comfortably under USD 30,000 in their final year, with the famous names clustering above the p90 line rather than on it.

Entry-year fees are roughly half of top-year across the city: median THB 300,000 (USD 8,400), bottom quartile under THB 230,000 (USD 6,400). Reception and Year 1 are where families with young children pin their budgets, not Year 12.

Bangkok sits almost exactly on the global median in ISG's cross-city benchmark. The city's USD 15,400 median is within USD 1,100 of the global USD 16,500 figure across the 50-city dataset. Where Bangkok stands out is the shape, not the level: a long premium tail that nearly doubles the city median, a denser value tier than Singapore or Hong Kong can offer, and a structural gap between the two that few other Asian capitals match.

The premium tier: USD 27,000 to USD 34,700

Twelve schools publish a top-year fee above THB 950,000 (USD 26,600). Five of them charge over USD 30,000 in the senior years.

Top-year day tuition, ages 16+ where the school publishes a Year 12 / Grade 12 figure.

The premium tier is almost entirely British or IB, with two American outliers in ISB and BASIS. Wellington and Shrewsbury sit slightly above the rest because their Year 12 fee absorbs a one-off external-exam loading; their Year 11 figures (USD 28,400 and USD 22,500) sit closer to the pack.

ISB is the structural anomaly: the only American-curriculum school in Bangkok pricing into the British ceiling, a non-profit founded in 1951 with the largest international school endowment in Thailand. Its THB 1.16 million top-year fee reflects facility and faculty depth, and its capital structure is one of the cleaner ones in the city, with no annual development fee on top of tuition.

The mid-tier: USD 9,000 to USD 22,000

The middle 50% of Bangkok's international schools sits between THB 342,000 and THB 768,000 (USD 9,600 to USD 21,500) at top-year. This is where most expat families choose from, and where the largest concentration of fee-publishing schools sits.

• British and Cambridge-track schools dominate the upper mid-tier (USD 16,000 to USD 22,000). Bangkok Patana, Concordian, Berkeley, Bangkok Prep, St Andrews and XCL American School sit here. Patana is the volume leader at this price point, with 2,200+ pupils and a full IB and IGCSE programme; its Year 13 fee of THB 975,000 (USD 27,300) brings it close to the premium tier.
• Newer Cambridge and bilingual schools cluster around the city median (USD 14,000 to USD 17,000). D-PREP, MYIS, Aster, Charter, RBIS, Astra Academy and the Lycée Français sit in this slot, several under five years old.
• Mid-tier American schools sit slightly below the British peers. International Community School, MABIS, BCIS Bangkok and ICS Nonthaburi all charge between THB 555,000 and THB 622,000 (USD 15,500 to USD 17,400) at the senior end.

A school priced at the THB 500,000 top-year mark is hiring teachers from the same recruitment pool as the British and Australian boarding schools' second-tier hires. The structural difference between USD 15,000 and USD 25,000 tuition in Bangkok is rarely about teaching quality and more often about facility depth, class size, and senior-school IB or A-Level breadth.

The value end: under USD 7,000

Twelve schools publish a top-year fee under THB 250,000 (USD 7,000). They split into three groups.

Adventist and faith-affiliated. Bangkok Adventist International (BAIS) at Sukhumvit charges THB 162,000 (USD 4,500) for its top year. Bangkok Grace, Ramkhamhaeng Advent and Ekamai International sit in the same band, all American-curriculum with AP, most with decades of operating history in Thailand. They serve a long-term resident and Asian-expat market more than the rotating Western-corporate cohort.

Cambridge-curriculum value schools. Centurion International, Kevalee, RC International and Knightsbridge House publish top-year fees between THB 155,000 and THB 245,000 (USD 4,300 to USD 6,900). Most are recent foundations, often outside central Bangkok, trading on a published British curriculum at a fraction of the Harrow or Shrewsbury price.

Thai-bilingual hybrids. Sarasas Ektra and Amnuay Silpa serve a primarily Thai cohort with English-medium delivery. Sarasas Ektra's range starts at THB 67,000 (USD 1,880) for entry years. Cohort composition is the variable here: a child arriving from London or Sydney is unlikely to find the EAL provision or peer-group English depth a fully international school provides.

What drives Bangkok's spread

Four structural factors explain why one Bangkok school can charge fourteen times what another does for a curriculum that, on paper, looks similar.

The baht's stability. The baht has traded in a narrow band against the dollar since 2022, with mid-2026 sitting around THB 35 to USD 1. Unlike Jakarta or Istanbul, where currency depreciation has compressed dollar-equivalent tuition, Bangkok's fees in USD terms have ticked upwards roughly 5% a year rather than swinging on macroeconomic shocks. Premium-tier schools price in baht and recover any FX gap through scheduled fee increases.

MoE Thailand registration and Thai-teaching requirements. Every international school operating in Thailand is licensed under the Ministry of Education's international-school framework, which requires a minimum number of teaching hours in Thai language and Thai culture for Thai-passport pupils. Schools serving a heavily Thai cohort carry the staffing cost of a dual-stream curriculum; schools with a primarily expat enrolment do not. The cost shows up in the bilingual tier of the fee table and in recently-licensed Cambridge schools that market dual-stream tracks.

Real estate and campus build-out. Wellington, Shrewsbury, Harrow and Brighton all opened or expanded purpose-built campuses in Bangkok between 2018 and 2025. The capital cost is amortised into tuition. Older schools with paid-down campuses, such as ISB at Nichada Thani or NIST at Sukhumvit Soi 15, carry lower amortisation loads even where headline fees match the new builds, which is partly why their facility reinvestment remains visible.

Teacher recruitment and cohort premium. A British-trained teacher choosing between Bangkok, Singapore and Hong Kong weighs three comparable expat lifestyles, so Bangkok schools compete on package. Premium-tier campuses pay housing allowances of THB 50,000 to THB 80,000 per month on top of base salary; mid-tier schools often do not. On top of teacher cost, a top-tier campus also charges for cohort access: parents pay a premium over a structurally identical mid-tier school for the alumni network and parent community, not for the curriculum.

Beyond the top-year tuition

Tuition is one line on the invoice. Three more sit alongside it.

Registration, application and deposits. At Wellington College, an application fee of THB 6,000, a security deposit of THB 175,000 and a registration fee of THB 225,000 must be paid before a place is confirmed; the deposit is refundable on departure, the registration fee is not. Shrewsbury charges THB 5,000 application, THB 225,000 Guaranteed Place Fee, and THB 225,000 refundable deposit. ISB charges THB 4,700 application and a THB 250,000 Annual Fee on enrolment. Dulwich, KIS Reignwood and Brighton sit in the same band. Year-one one-off costs at the top tier add THB 200,000 to THB 450,000 (USD 5,600 to USD 12,600) before the first tuition invoice.

Capital charges. Most Bangkok international schools fold campus investment into tuition rather than charging a separate annual development levy. KIS Reignwood Park's THB 250,000 refundable one-off School Development Fund is one of few exceptions. This is structurally different from Jakarta or Singapore, where recurring annual capital levies of USD 1,500 to USD 6,000 are routine. Families moving from those cities can usually drop the recurring-levy line from their Bangkok budget.

Transport, uniforms, exam fees, trips. School bus subscription typically runs THB 50,000 to THB 100,000 per year at the premium tier; uniforms THB 10,000 to THB 25,000 at first enrolment. IGCSE, IB Diploma or AP exam fees add THB 30,000 to THB 80,000 across Year 11 and the Year 12 to Year 13 final cycle. Residential and overseas trips add another THB 30,000 to THB 80,000 per year at premium schools.

A realistic first-year all-in cost for a family of two children at a premium British school in Bangkok is THB 2.4 million to THB 3.1 million (USD 67,000 to USD 87,000), against published tuition of roughly THB 1.6 million to THB 2.2 million. The gap between published and paid is 20% to 35% at the premium tier, narrower further down the market.

Fees themselves step up annually by 4% to 7%, with premium-tier schools at the higher end. Over a five-year posting at 6% a year, fees compound by 34%: a USD 30,000 top-year fee becomes roughly USD 40,000 by Year 13. For families on a fixed employer schooling allowance, that compounding is the single biggest budget risk over a multi-year stay.
