Bangkok International School Fees 2026/2027: What Tuition Actually Costs

From 2014 to 2020, I sent my two kids to different international schools in Bangkok: The American School of Bangkok, KIS International School, and The International Community School (ICS). Each school came with its positives and challenges, but my kids greatly benefited from their time spent there. Ultimately we ended up moving back to the USA for a number of reasons, but that is something I will get into later.

I also worked in marketing and admissions for both The American School of Bangkok and for KIS International School. This required me to know a lot about not only those schools, but the international school landscape in Bangkok and the surrounding areas. I can tell you that the biggest three factors when choosing a school are typically these: price, location, and curriculum.

While there are many other factors, let us dive into the first one, price. Every guide to Bangkok school fees I have read gives you a vague band, something like 400,000 to 900,000 baht a year, and calls it a day. That is not actually useful when you are trying to budget for a specific child at a specific school for the 2026/2027 school year. So instead of estimating, I pulled the real published tuition ranges for more than 45 schools in our own directory and sorted them by tier. These are actual numbers schools have published for the current fee cycle, not averages I made up.

Premium tier: over 900,000 THB

This is Ruamrudee at 548,400 to 1,527,000 baht a year, Wellington at 615,250 to 1,240,137, Shrewsbury at 691,800 to 1,208,400, International School Bangkok at 681,000 to 1,219,000, and NIST at 650,200 to 1,132,800. Harrow, Bangkok Patana, and King's College all land in a similar range, roughly 545,000 to just over a million depending on year group. These are the schools with decades of history, extensive facilities, and university counseling offices that genuinely know how to get kids into competitive programs abroad. You are paying for that infrastructure as much as the classroom itself.

Upper mid tier: 400,000 to 800,000 THB

Concordian runs 626,400 to 963,400, Bromsgrove 259,100 to 680,100, Regent's 430,800 to 759,600, KIS 459,800 to 984,700, BASIS 545,000 to 998,000, and Berkeley 519,200 to 839,200. This is where a lot of genuinely strong academic options sit, often 20 to 30 percent cheaper than the premium tier for outcomes that are honestly not that different at the primary level. The gap widens more in the senior years.

Mid tier: 250,000 to 550,000 THB

Astra Academy sits at 516,600 to 550,200, Australian International School Bangkok at 322,000 to 520,000, Charter at 270,000 to 594,000, DPREP at 320,000 to 580,000, and Traill at 358,200 to 558,000. Hampton, a Reggio Emilia early years school, runs 326,000 to 494,000, which tells you early years pricing does not always track with primary and secondary the way you would expect.

Value tier: under 350,000 THB

This is where the real savings live if the specific curriculum and campus fit your family. Modern International School Bangkok runs 199,500 to 260,100, Raffles American School 198,000 to 297,000, Trinity 198,000 to 220,870, Canadian International School of Thailand 198,500 to 545,000 depending heavily on year group, and Bangkok Christian International School as low as 84,000 to 136,000. Sarasas Ektra, a bilingual Thai English school, runs just 67,000 to 151,200 a year, which is a fraction of what the premium schools charge for a genuinely different but still solid academic option.

The hidden fees nobody puts on the front page

Tuition is usually only 75 to 85 percent of what you will actually pay in year one. Almost every school charges an application fee, typically 5,000 to 15,000 baht, plus a registration or enrollment fee that can run anywhere from 50,000 to 250,000 baht depending on the school, and this is separate from tuition and rarely refundable. On top of that, expect a capital or development levy at some schools, another 100,000 to 400,000 baht, sometimes partially refundable if you stay long enough, sometimes not refundable at all. Always ask which category you are in before you sign anything.

Beyond the entry fees, budget for a school bus if you need one, typically 45,000 to 85,000 baht a year depending on distance, and factor in that Bangkok traffic means a bus route that looks reasonable on a map can still mean an hour each way. Exam registration for IGCSE, IB Diploma, or AP years is usually billed separately too, often 30,000 to 80,000 baht in the relevant year, and boarding, where it is offered at all, adds another 300,000 to 600,000 baht on top of day tuition.

How to actually save money on Bangkok school fees

A few practical things I have learned the hard way. Sibling discounts are common, usually 5 to 15 percent starting from the second child, but they do not always stack with scholarships, so ask specifically. Most schools invoice in three terms and offer a small discount if you pay the full year upfront in August. If your employer is covering tuition as part of a relocation package, get in writing whether that covers just tuition or the capital levy and registration fees too, since that single detail can move your real out of pocket cost by six figures.

If you are earning in a currency other than baht, keep an eye on timing. Almost every school here invoices in THB only, and a 3 percent swing in the exchange rate between accepting a place and your first invoice is a real number, not a rounding error. A few schools let you lock in an advance payment at a fixed rate, which is worth asking about if your income is in USD, GBP, EUR, or SGD.

My honest advice: shortlist three to five schools across at least two different tiers before you start touring campuses. It is the only way to actually see whether the extra 300,000 or 400,000 baht a year at the premium tier is buying you something your family genuinely needs, or whether a strong mid tier or value tier option gets your kid to the same place for a lot less money.
