We ran the geoarbitrage math. Housing: ✓. Food: ✓. Healthcare: ✓. Then we looked up school fees.
My husband and I had spent six months building a beautiful spreadsheet. We were serious about the moving abroad with kids budget — we’d priced out every expense category obsessively except this one. We knew to the dollar what we’d save on rent moving from Austin to Medellín. We’d priced out groceries, utilities, health insurance, even date nights. The numbers were intoxicating — nearly $2,500 a month in savings, $30,000 a year, handed back to us just for choosing a different zip code. Then our oldest asked the obvious question: “Where are we going to school?”
That question sent me down a rabbit hole that nearly derailed our entire move. The cost of international schools abroad for expat families is one of the most underestimated line items in the expat budget — and for families with two or more children, it can single-handedly wipe out every dollar of savings that made the move feel worth it in the first place.
Why International Schools Are So Expensive
International schools aren’t just “nicer” schools. They’re a specific product designed for a specific market: expat families who want English-language instruction, an internationally recognized curriculum (typically IB or Cambridge A-Levels), and a diploma that will transfer back to a US, UK, or Australian university without a fight. The schools that deliver all of that reliably have to hire certified Western teachers, maintain accreditation, and run facilities that meet the expectations of families used to well-funded suburban American or British schools.
That costs money. And in many cities — Singapore, Dubai, Bangkok — the demand so far exceeds the supply of quality spots that schools can charge essentially whatever they want.

These are annual tuition ranges per child, in USD, based on current enrollment data from school websites and expat community reporting. International school fees Bangkok, Singapore, and Dubai command a significant premium over Latin American and Eastern European cities. Costs exclude enrollment fees, capital levies, uniforms, school trips, and activity fees — which can add 10–20% on top.

The Math That Almost Made Us Stay Home
Let me run the numbers for our situation — two kids, Medellín — because this is where the geoarbitrage dream can hit a wall fast.
We estimated $2,500/month in savings on rent, food, and transport. Over a year, that’s $30,000 back in our pocket before schools enter the picture. Sounds great. Then we priced international schools.
Two kids at a mid-tier IB-accredited school in Medellín: roughly $10,000–$12,000 per child, or $20,000–$24,000 per year total. Subtract that from the $30,000 in savings and our net geoarbitrage gain is somewhere between $6,000 and $10,000 per year.
That’s not nothing. But it’s not the financial transformation we’d imagined. When you factor in the one-time costs of the move itself — flights, shipping a few boxes, rental deposits, setting up a new household — year one can actually be a wash or worse. You’re not moving abroad to get rich. You’re doing it to build a slightly better lifestyle for roughly the same money. That realization forced us to ask harder questions about what we actually wanted.
For families in higher-cost destinations — Singapore with two kids at international schools runs $50,000–$110,000 per year in tuition alone — the math flips entirely negative. The expat family education costs in premium cities can turn a smart financial move into an expensive lifestyle choice disguised as arbitrage.
The Alternatives That Actually Work
Once we accepted that international school fees might not fit our budget, we started seriously researching the options. Here’s what we found.
1. Local Public School
Public school abroad for Americans is an underused option. In most countries — Colombia, Portugal, Germany, Thailand — local public school is free. The catch is obvious: instruction is in the local language. For kids under 10, this is often less of a barrier than parents fear. Children that young acquire languages with a speed that frankly embarrassing compared to their parents. Full immersion at a local school is hard for the first three to six months, and then it becomes transformative.
The risks are real for older kids. A 14-year-old dropped into a Spanish-language school mid-semester faces genuine academic disruption that can affect transcript quality and college applications. But for families with elementary-age children, local public school deserves serious consideration — not just as a budget option, but as an experience that builds bilingual kids faster than any tutoring program ever could. This is what we ultimately chose for our 8-year-old.
2. Homeschooling Abroad
Homeschooling is legal in most expat-popular countries, including Colombia, Mexico, Portugal, and Thailand. Curriculum costs run roughly $1,500–$3,000 per year per child using established programs like Sonlight (literature-based, excellent for storytellers), Time4Learning (online, self-paced, popular for digital nomad families), or the free Khan Academy plus supplemental materials.
The cost savings are dramatic. The time commitment is also dramatic. One parent needs to own the school day — structuring lessons, monitoring progress, handling social learning gaps. For dual-income remote families who moved abroad to work more effectively, not to become full-time teachers, homeschooling for Americans abroad can create as many problems as it solves. It works best for families where one parent genuinely wants this role, not just tolerates it.
3. Online Schools
Online schooling has matured significantly in the last decade. Options include:
- Florida Virtual School (FLVS) — Accredited, US-recognized, free for Florida residents, low-cost for out-of-state families. Works anywhere with reliable internet.
- Connections Academy — Tuition-free for qualifying US students; curriculum is structured and teacher-supported.
- Khan Academy — Free, excellent for math and science supplementation, but not a standalone accredited school.
- Bridgeway Academy, Laurel Springs, or Calvert — Paid online programs ranging $2,000–$5,000/year with full accreditation and transcript services.
The total cost runs from free to roughly $3,000–$5,000 per child per year. Transcripts are US-accredited. The drawback: screen time is heavy, social interaction requires deliberate effort, and kids need strong self-motivation or active parental oversight. For disciplined teenagers or structured families, this is often the cleanest solution when moving abroad with kids on a budget.
4. The Hybrid Approach
Some families do mornings at a local school for language immersion and socialization, then afternoons of online supplemental work in English to maintain grade-level progress in math, reading, and writing. This sounds exhausting — and some weeks it is — but it threads the needle between cost, social integration, and academic continuity in a way that neither extreme achieves alone.
5. Cheaper International Schools
If you’re committed to international school but want to keep costs manageable, location selection is the most powerful lever you have. Chiang Mai, Prague, and Medellín all have IB-accredited or Cambridge-accredited international schools charging under $8,000 per child per year. That changes the family math substantially. Two kids in Chiang Mai at $7,000 each is $14,000 — not cheap, but it preserves meaningful geoarbitrage savings rather than consuming them.
What to Ask Before Enrolling Anywhere
Whether you’re eyeing a $10,000 school in Medellín or a $40,000 campus in Dubai, these questions will save you from expensive surprises:
- Is it IB or Cambridge accredited — or just claiming to be? Accreditation is verifiable. Look it up on the IBO website or Cambridge International before paying any enrollment deposit.
- Will credits transfer back to a US high school? For elementary-age kids this matters less. For middle and high schoolers, a transcript that doesn’t map to US credit standards can create serious college admissions complications.
- What is the enrollment fee and capital levy? Many international schools charge a one-time enrollment fee of $1,000–$5,000 plus an annual “capital levy” or “building fund” contribution. These are often non-refundable.
- What are the additional fees? Uniforms, school trips, after-school activities, lunch programs, and bus service can add $2,000–$6,000 per child beyond tuition.
- What is the student demographic mix? Some international schools are genuinely international. Others are primarily serving one expat community — which affects your child’s social experience and the culture of the school.
- What is the school’s withdrawal policy? Life abroad changes. Know what happens if you need to leave mid-year.
The Language Immersion Argument — and When It Actually Works
The research on childhood language acquisition is unambiguous: kids under 12 — and especially under 8 — acquire second languages with a fluency and accent authenticity that adults simply cannot replicate. A year of full immersion in a local school does more for a child’s Spanish than a decade of Saturday classes back home.
But this argument has limits. It works best when the family commits to staying in the country for at least two years, so the child has time to move past the painful adjustment phase and into actual fluency. It works best for younger children whose academic progress won’t be permanently derailed by a language gap. And it works best when parents invest time in helping with the transition — not outsourcing the entire struggle to the child.
For families planning a one-year stint before returning to the US, throwing a 13-year-old into a local school carries more academic risk than reward. For a family with a 7-year-old planning to stay three or more years, it’s often the single best thing they can do for their kid’s long-term cognitive development — and it’s free.
The Social and Emotional Reality Nobody Talks About
International schools offer one thing that’s genuinely hard to replicate: a community of other expat kids going through the same experience. Your child isn’t the only one who doesn’t speak the local language fluently. They’re not the only one who misses their grandmother. The international school peer group becomes a safety net that matters enormously, especially in the first year.
Local public schools can be socially isolating, at least initially. Online schools have zero organic socialization — you have to manufacture it entirely through co-ops, activities, and playdates. Homeschooling has the same problem multiplied.
For kids who are already socially anxious or who are moving at a difficult developmental moment — early middle school, for instance — the social safety net of an international school may be worth a significant financial premium. This is a legitimate consideration, not just an excuse to spend money. Our younger child struggled socially for four months in a local school before finding her footing. That was four months I’d do differently if I could.
The Verdict: Which Approach Fits Which Family
After a year in Medellín, here’s the honest summary I wish someone had handed me before we moved:
| Family Type | Best Education Approach |
|---|---|
| Kids under 10, staying 2+ years, one parent with flexibility | Local public school + Khan Academy supplemental |
| High-school-age kids, college-track, any length of stay | Accredited online school (FLVS, Laurel Springs) or affordable IB school in Chiang Mai/Prague |
| Both parents working remotely full-time, structured kids | Online school (Connections Academy, Time4Learning) |
| One parent willing to teach, long-term move | Homeschooling abroad — biggest savings, biggest commitment |
| Short stay (under 1 year), any age | Online school — avoid disrupting enrollment at brick-and-mortar schools |
| Financial priority is geoarbitrage, budget is tight | Chiang Mai or Prague international schools; avoid Singapore, Dubai, Bangkok tier-1 |
The cost of international schools abroad for expat families is real, it’s substantial, and it belongs in your budget spreadsheet before you book the flights. Not to scare you off the move — but to help you choose a city and a school strategy that makes the whole thing work financially and personally. The families who do this well don’t just pick the city with the best weather. They pick the city where the education math doesn’t destroy the rest of the plan.
Bottom Line
If you’re moving abroad with kids, run this calculation before anything else: total international school fees for all your children, in the specific city you’re considering, versus your projected savings. If the number is negative or barely positive, either choose a cheaper schooling path or choose a cheaper city. Prague and Chiang Mai exist for a reason. Medellín’s schools are better value than Bangkok’s. The geoarbitrage is real — but only if you do the full math.
