Tuition by year group.
Tap a row for the source and the sum.
Every row above is from the school's own fee schedule at drive.google.com (pdf), read on 27 October 2026. Nothing is estimated or taken from a third-party site. Where a row says so, the annual figure is the school’s termly fee multiplied by the number of terms.
One-off fees and deposits.
Same source and date as the tuition table: drive.google.com, checked 27 October 2026.
Fees marked as an alternative or special case (a per-family rate instead of per child, a boarding deposit instead of the day deposit, a waiting-list fee) are listed but not added into the totals, so that the first-year figure is what one day pupil pays on the standard route.
What the fee schedule says.
- Payment. Two semesters; 1.5% discount for one annual payment of tuition. Billing: Semester 1 invoiced 1 April 2026 due 1 May 2026; Semester 2 invoiced 1 Oct 2026 due 1 Nov 2026. Late charge 2,000 baht per invoice.
- Annual figures are 2 x the semester figures (derived); the PDF's own 'Total Annual Fee' column includes the 1.5% annual-payment discount (e.g. KG 305,350). Fees include snack and lunch, textbooks, foreign language lessons, curricular music programme and student insurance. Sibling discount on School Development Fee: 2nd child 50,000; 3rd child 100,000. Other optional fees per semester: English/Maths support 30,000, Japanese 9,000, extra ECA 6,000, swimming ECA 10,000, daycare 9,000, summer school 40,000, IGCSE exam 10,000 per subject. The fee PDF is shared via a Google Drive link behind the 'Get School Fees' button on https://stmarks.ac.th/admission (the school's own page); it is not hosted on the school's domain. stmarks.ac.th is 'St. Marks Australian International School' (operating since 1999 per its homepage), whose contact page lists a Srinakarin campus and a Rama 9 campus and does not mention Bang Na; the fee PDF does not say which campus. Fee year note: publication date 20 Feb 2026.
What it costs in pounds, and why that moves.
The school bills in baht. A British family paying from sterling income pays a different amount every term because GBP/THB moves. The same Year 7-10 fee of 444,000 THB is:
| GBP/THB | Annual fee in pounds |
|---|---|
| 48 | £9,250 |
| 44.9 (today) | £9,888 |
| 42 | £10,571 |
Between a strong-pound year and a weak one the sterling cost of this school moves by about £1,321 a year per child. A family paying termly from a UK account at a high-street bank's 3 to 5 per cent spread adds £396 a year on top. Fee payments are the single largest transfer most expat families make, which is why the transfer method matters more here than anywhere else in the budget.
A termly 148,000 THB transfer at the mid-market rate costs a fraction of a bank's spread. Compare the GBP to THB quote before the first invoice.

Reading the fee schedule
- The hidden fees catalogue: the £30,000 to £70,000 your school will charge that is not in the tuition schedule.
- The fee inflation trap: how £18,000 in Year 1 becomes £32,000 by Year 13.
- The British family's decision framework for international schools in Asia.
- Where the £25,000 actually goes: the international school operating budget nobody publishes.
How The Baht records school fees
Every figure comes from the school's own website or fee document, recorded with its URL and the date it was checked. Figures are annual tuition as the school states them, in Thai baht, for the academic year shown. Where a school prints termly fees only, the annual figure is the termly fee multiplied by the number of terms and is marked as such. Refundable deposits are listed but excluded from first-year totals. Pound figures use the mid-market GBP/THB rate on the day the page was built (Latest daily mid-market snapshot · 10 November 2026) and are rounded to the nearest pound. Fee schedules change every year, usually between March and July; the checked date on this page is the date the figures were last read from the school's site. Corrections: editorial@thebaht.com.
