Chulalongkorn University requires payment for tuition and fees at the start of each term. The amounts are determined by the study requirements of each faculty. In addition to tuition, the payment will include entrance fee, activities fee, insurance premium, and courses registration as well as special fees announced by the university.

The first term and second term fees will differ according to departments, programs and curriculums. The fees for the summer term are usually the same for all non-Thai students but different than those for Thai students, in accordance with Thai law.

New students entering the first term can pay their tuition fees with cash, cashier check or bank draft. After this, students must make their payments through their student savings account in the Siam Commercial Bank Plc., which they must open during their first term of study.
