Koh Samui runs pricier than most other Thai islands, largely because Bangkok Airways’ ownership of the airport pushes up everything from flights to the general cost of doing business, but it’s still genuinely possible to visit on a real budget if you know where the costs actually land. This breaks down what a day on Samui costs across three realistic tiers, based on real accommodation, food, and transport prices.
Three Daily Budget Tiers
| Tier | Roughly per day | What it gets you |
|---|---|---|
| Budget | ~800-1,000 THB ($22-28) | Guesthouse room, street food and markets, songthaews and scooter rental |
| Mid-Range | ~2,500-4,500 THB ($70-125) | Air-conditioned hotel with a pool, mixed restaurant dining, occasional Grab/tours |
| Luxury | 8,000 THB+ ($225+) | Beachfront resort, restaurant and fine dining, private transfers and tours |
Budget: ~800-1,000 THB/day
A private room in a genuine budget guesthouse runs 300-600 THB a night, see our best budget guesthouses in Koh Samui guide for real, currently open options across the island. Street-market meals and simple Thai restaurants run 60-100 THB per meal, and a scooter rental (150-300 THB a day) or songthaew trips (50-150 THB each) cover getting around. This tier works well if you’re comfortable with basic rooms and eating mostly local food rather than restaurant dining every meal.
Mid-Range: ~2,500-4,500 THB/day
A comfortable air-conditioned hotel with a pool runs roughly 1,500-3,000 THB a night in this tier, see our Koh Samui hotel prices guide for the full price-by-tier breakdown. Food shifts toward a mix of sit-down restaurants and casual dining, 300-700 THB per person per meal at the kind of places covered in our Koh Samui food guide, and transport moves to Grab rides and the occasional organized day tour rather than pure songthaew-hopping.
Luxury: 8,000 THB+/day
A beachfront resort room or pool villa starts around 5,000-8,000 THB a night at this tier and climbs well beyond that for the island’s top-tier properties, restaurant and fine dining (including a splurge like the Michelin-recommended Koh Thai Kitchen) push food costs to 1,500-3,000 THB or more per person, and private transfers and higher-end tours (an Ang Thong luxury speedboat, a private driver for the day) replace shared transport entirely.
What Drives Costs Up or Down
Season matters more on Samui than almost anywhere else in Thailand, high season (December-February) can push accommodation prices 40-60% above the September-October low season, a bigger swing than Phuket or Krabi see for the same calendar window. Location matters too: Chaweng and the resort-heavy north coast (Choeng Mon, Maenam) generally run pricier than Lamai, Bang Rak, or the quieter west coast for a comparable room. And because Bangkok Airways privately owns Samui’s airport, arriving by direct flight rather than the fly-to-Surat-Thani-plus-ferry route adds real cost before you’ve spent a single baht on the island itself.
Hidden Costs to Budget For
A handful of costs catch first-time visitors off guard: the Ang Thong National Park day trip runs 1,500-2,500 THB depending on the operator and boat type, a genuine splurge but close to essential for a first Samui visit. Many restaurants and hotels add a 10% service charge plus 7% VAT to the bill, which can add up faster than expected across a week of dining out. And since there’s no metered taxi system, negotiating every ride adds friction (and occasionally overpaying) that doesn’t exist on islands with Grab-only or metered transport.
Money-Saving Tips for Koh Samui on a Budget
Eat where locals eat: a market meal costs a fraction of a beachfront restaurant for genuinely good food. Book accommodation directly with smaller guesthouses and boutique hotels rather than through OTAs when possible, several properties on the island offer a better direct rate. Travel in the shoulder months (late April-early June, late September-October) for a meaningful discount on accommodation without the wettest weather of the true low season. And rent a scooter by the week rather than the day if you’re staying more than a few days, the per-day rate drops noticeably.
Budgeting for a Family
A family of four traveling mid-range should plan for roughly double the per-person mid-range figure above once a larger room or a second room is factored in, plus extra costs for kids’ activities and the inevitable additional snacks and drinks. Several of the island’s family resorts (see our best family resorts in Koh Samui guide) offer family-sized rooms or villas that work out more efficient per person than two separate hotel rooms.
How Koh Samui Compares to Phuket and Krabi
Samui runs noticeably pricier than Krabi at every tier and somewhat above Phuket on accommodation specifically, largely a function of the airport situation and a smaller overall room supply relative to demand. Food and local transport costs are broadly comparable across all three islands; the accommodation and flight cost gap is where Samui’s higher overall budget really shows up.
A Sample Mid-Range Day
| Item | Roughly |
|---|---|
| Hotel room (per night, split if traveling as a couple) | 1,500-3,000 THB |
| Breakfast | 150-250 THB |
| Lunch | 250-400 THB |
| Dinner | 400-700 THB |
| Grab rides / scooter rental | 150-300 THB |
| One activity or tour (averaged across the trip) | 400-800 THB |
That puts a realistic mid-range day, excluding the accommodation cost, at roughly 1,350-2,450 THB per person on food, transport, and activities, broadly consistent with the mid-range tier above once a shared hotel room is factored in. Building in one splurge day (an Ang Thong tour, a nicer dinner) and a few quieter, cheaper days around it is a more realistic way to budget a week-long trip than assuming every day costs the same. For getting between all of this, see our guide to getting around Koh Samui.

Frequently Asked Questions
Is Koh Samui more expensive than Phuket?
Generally yes, particularly for accommodation and flights, largely because of the airport’s private ownership and a comparatively smaller room supply.
Can you visit Koh Samui on a tight budget?
Yes, a genuine budget day (guesthouse, street food, songthaews) runs around 800-1,000 THB, though flights or the fly-plus-ferry connection to the island add a real cost on top of daily spending.
How much should I budget for Ang Thong National Park?
Plan for 1,500-2,500 THB for a standard group day trip, more for a private speedboat or luxury option.
Is it cheaper to visit in low season?
Yes, accommodation in particular can run 40-60% cheaper in low season (roughly May-October, excluding the wettest weeks) compared to December-February high season.
Do I need to budget for service charge and VAT separately?
Many restaurants and hotels add a combined 17% (10% service charge plus 7% VAT) to the bill, worth factoring into your daily food and accommodation budget rather than treating menu and rate-sheet prices as final.
