Cost of Living on Koh Samui in 2026: What You Really Need Per Month
What it really costs to live on Koh Samui: housing, food, transport, healthcare and school. Real numbers for a family and for a single person. No agency gloss.
One of the most common questions from people considering a winter stay or relocation to Samui: "How much do you really need per month?" The answer depends on your lifestyle — but with specific figures, you can form an honest picture.
Housing: The Biggest Expense
Accommodation is the most variable cost. Prices vary significantly by area, lease length, and property type.
Long-term rental (3+ months) — approximate 2025–2026 ranges:
| Property Type | Range/month (฿) | Range/month (~USD) |
|---|---|---|
| Studio / 1-bedroom apartment | ฿8,000–20,000 | ~$240–600 |
| 2-bedroom house / townhouse | ฿18,000–40,000 | ~$550–1,200 |
| 2–3 bedroom villa with pool | ฿35,000–80,000 | ~$1,050–2,400 |
| 4–5 bedroom premium villa | ฿80,000–200,000+ | ~$2,400–6,000+ |
Important caveats: Long-term rental rates (3+ months) are 15–30% lower than short-term rates. Location matters greatly: Chaweng is more expensive than Maenam for comparable sizes. Seasonality: peak-season properties (November–April) may require a premium or only offer short-term leases.

Food
Samui offers three price tiers, and the difference between them is substantial.
Thai street food (stalls, markets, local cafes): Pad thai, fried rice, soup — 60–120 THB. Fresh fruit smoothie — 40–60 THB. Thai breakfast (egg, rice, soup) — 60–100 THB. Full lunch — 150–250 THB.
Tourist cafes and mid-range restaurants: Main course — 180–400 THB. Glass of beer — 80–150 THB. Iced latte — 80–120 THB.
Hotel restaurants and fine dining: Main course from 400 THB and up.
Realistic monthly food budget: Street food only (2–3 meals/day) — ฿6,000–9,000/month per person. Mixed (home cooking + cafes) — ฿10,000–15,000/month. Restaurants several times a week — ฿15,000–25,000/month.
Supermarkets: Big C and Lotus's in Chaweng carry European and Asian products. Imported goods cost 1.5–2× more than local equivalents.
Transportation
Public transport on Samui is songthaews (red pickup truck minibuses). Cost: 60–150 THB per ride on the ring road. Expensive and impractical for regular use due to no fixed schedule.
Scooter: the primary transport for most residents. Rental: ฿2,500–4,000/month. Petrol: ฿2,500–4,000/month with regular use. Total ~฿6,000–8,000/month. Insurance and licences: check with your landlord — formal requirements do exist.
Car: rental from ฿10,000–18,000/month for a small car. Petrol ฿5,000–8,000/month. Total ฿15,000–26,000/month — makes sense for families with children or those who prefer not to ride a scooter.
Grab (taxi app): works on the island. A ride: ฿120–350. Convenient for occasional trips, but expensive as daily transport.
Healthcare
Samui has three international-class private hospitals: Bangkok Hospital Samui (largest), Samui International Hospital, and Bandon International Hospital. Quality of care for standard cases is good. Complex procedures are handled in Bangkok.
GP consultation: ฿500–1,500 without insurance. Standard check-up plus prescription is reasonable. Complex diagnostics and hospitalisation are expensive without coverage.
Recommendation: get international health insurance. Cost depends on age and coverage: $50–200/month for a healthy adult. Without insurance, a hospital stay can run ฿50,000–200,000+.
Schools (for Families with Children)
Samui has several international schools: Samui International School — popular with expats, British curriculum. St. Andrew's International School Samui — international programme. Local Thai schools — for Thai-speaking children.
International school fees: ฿120,000–250,000 per year per child. This is a significant budget item for families.
Utilities
In most rental villas, utilities are billed separately.
Electricity: Samui has high rates by Thai standards (the island purchases power from the mainland). With regular AC use in warm months: ฿3,000–8,000/month for a small villa. Always verify the rate with your landlord: some charge the government rate (~฿4/kWh), others mark it up to ฿8–9/kWh.
Water: ฿500–1,500/month.
Internet: fixed FTTH — ฿500–800/month for a good connection. 4G coverage across the island is stable.
Budget Summary
| Lifestyle | Housing | Food | Transport | Other | Total/month |
|---|---|---|---|---|---|
| Minimal (apartment, markets, scooter) | ฿10,000 | ฿8,000 | ฿6,000 | ฿4,000 | ฿28,000 (~$850) |
| Comfortable (villa with pool, cafes, scooter) | ฿40,000 | ฿15,000 | ฿7,000 | ฿10,000 | ฿72,000 (~$2,200) |
| Family with two children (3BR, school, car) | ฿55,000 | ฿20,000 | ฿20,000 | ฿25,000 | ฿120,000+ (~$3,600+) |
USD conversion is approximate. Track the current THB/USD rate independently.
Realistic minimum budget for comfortable living without schools or a car — ฿40,000–50,000/month (~$1,200–1,500). For a family with children — ฿100,000–150,000+ (~$3,000–4,500).
What's Not Included
- Visa and immigration costs (border run, extension, DTV) — every 30–90 days, ฿1,500–5,000 per event. Details: visa guide
- Insurance (health + property)
- Travel off the island (ferry to Phangan, Koh Tao — ฿200–400 return)
- Activities and tours: diving ฿2,500–3,500/day, tours from ฿800
Housing Is Your Main Budget Control
The most obvious way to reduce costs is to choose a less expensive area. Maenam and northern Chaweng offer similar living conditions at 20–40% lower prices than central Chaweng or Lamai.
Signing a 3–6 month lease upfront reduces the monthly rate by 15–25% compared to month-to-month.
