Curriculum is usually the biggest factor. A full boxed curriculum with recorded lessons, grading and accreditation costs more than an open ended approach built from free or low cost materials. Families chasing a recognized diploma or standardized testing tend to spend more than those doing an unschooling style approach.

Outside subjects add to the total too. Many parents hire tutors for Indonesian language, advanced math, or a specific skill like music or swimming. Rates vary depending on qualifications and whether the tutor travels to you or teaches online. Shipping books in from overseas, or paying for a subscription billed in another currency, usually costs more than sourcing what's already available on the island.
How you structure the school day matters as well. Joining a homeschool co-op or learning pod means splitting the cost of shared space, a hired teacher for group sessions, or transport for field trips, which is often lighter on the wallet than solo one on one tutoring. Compare homeschool co-ops against solo homeschooling before you settle on a structure. Many families also weigh the whole path against international school versus homeschooling in Bali, since school fees, uniforms and bus costs set the baseline they measure against.
