What It Actually Costs to Raise a Family on a Thai Island
The real monthly numbers, the three ways people make a living here, and the thing it took me a while to see.
How much does it cost for a family to live in Koh Samui, Thailand?
In short: the average monthly expenses for a Western family with two or three children run between 200,000–300,000 THB a month - roughly $6,000–9,000.
The hardest part of living here isn’t the cost, though. It’s earning the money in the first place. Broadly, I see three ways people make a living on the island:
Digital nomads - working on a laptop for a company that pays a Western salary, or running their online business from here.
Local earners - making a living on the island itself, usually through tourism or real estate.
The retired - pensioners, people who’ve sold a business, inheritors. Essentially, those who don’t need to work anymore.
Here’s where the money actually goes, for a typical Western family:
Housing: 70,000 THB (~$2,150) / month
International school: 20,000 THB (~$615) per child / month
Food (groceries + eating out): 50,000 THB (~$1,540) / month
Car: 20,000 THB (~$615) / month
Health insurance (whole family): 10,000 THB (~$310) / month
Activities (kids and parents): 10,000 THB (~$310) / month
On top of that come the smaller things - electricity, water, fuel, household shopping, the occasional massage, a babysitter, day trips. And the schools here have a lot of holidays, which quietly turns into real money: camps, trips, and activities to fill the weeks the kids are off.
What surprised me most wasn’t any single number. It was the contrast. An average Thai family here lives on around 30,000 THB a month - about $900. You’ll see five of them on one old scooter, and they seem genuinely happy with their life. I don’t want to romanticize it - 30,000 THB is tight, and “happy on less” is easier to admire from the outside. But it has stuck with me as a question I keep turning over: how much of what we spend actually buys us anything that matters?
