Tip · Plan island days at the top of your range, because taxis and boat trips on Phuket and Samui cost much more than getting around Bangkok or Chiang Mai.
A 50 or 60 baht plate of pad kra pao makes Thailand look cheaper than it is. Street food stays around that price in Bangkok and Chiang Mai, a bit more on the islands, but rooms, island taxis, boat trips and bar prices don't, and they move your total far more than food does.
The numbers here are per person, per day, for two people sharing a room, with flights and travel between cities left out. They're October 2026 prices at 33.5 baht to the dollar, so 1,000 baht is about $30. In Bangkok I stay in a hotel near the BTS in Silom or Ari, which puts me in the mid-range bracket. On my last trip we averaged about $100 a day each, around 3,350 baht, so near the top of it.
Daily budgets at three styles
| Style | Per person, per day |
|---|---|
| Backpacker | 1,000–1,500 THB, $30–45 |
| Mid-range | 2,500–3,500 THB, $75–105 |
| Comfort | 6,000+ THB, $180 and up |
Few trips sit neatly in one row. Most mix cheap days in Chiang Mai with expensive ones on an island, so treat them as rough markers. On your own in a private room, add your half of the room again. A dorm bed is already per person.
Backpacker: 1,000–1,500 baht a day
A cheap day in Bangkok can look like this: moo ping and sticky rice for breakfast at 40 baht, pad see ew from a cart at lunch for 50, the MRT to Sanam Chai and back at 17 to 44 baht a ride, Wat Pho at 300, dinner at a night market for around 100, a large Chang from 7-Eleven and a dorm bed in one of the popular hostels for 400 to 700. With water and an iced coffee that comes to roughly 1,050 to 1,400.
Chiang Mai dorms are 150 to 350, about half of Bangkok's. A simple private room is 300 to 800 baht, and two people sharing one often pay less than two dorm beds would cost, with a door that locks.
Mid-range: 2,500–3,500 baht a day
This is a hotel with air conditioning, often with a pool, at 1,500 to 2,500 baht a night, which is 750 to 1,250 each when two of you share. Mid-range rooms run from 1,000 to 3,000 a night and I'd aim for the middle of that. Going from a 400 baht room to a 1,500 one is a big upgrade, and paying 4,000 in a city mostly gets you a nicer lobby. I check Bangkok prices on Agoda first. What to look for in a listing is in the hotels guide.
Food at this level is a stall breakfast and a couple of sit-down meals, where a main is 150 to 350 baht. You'll take more Grab cars on hot afternoons, at 70 to 120 baht for a short hop in Bangkok, and most days there's something paid, like a half-day cooking class at 800 to 1,500 or an island trip.
Comfort: 6,000 baht a day and up
Six thousand a day buys your half of a resort room from 5,000 baht a night, restaurants and hotel bars, private transfers between places, and a private boat or a guide on some of the island days. It goes up from there, and over Christmas a pool villa on Phuket can cost two to three times its usual rate.
Getting between cities
These are one-way prices per person, apart from the taxi, which is per car.
| Leg | Cost |
|---|---|
| Airport to central Bangkok | 45 THB on the Airport Rail Link, 350–550 THB per taxi |
| Sleeper train, Bangkok to Chiang Mai, second class | 850–1,050 THB |
| Overnight bus, Bangkok to Chiang Mai | 500–900 THB |
| Flight, Bangkok to Chiang Mai, Krabi or Phuket | 1,000–2,000 THB, plus 400–660 THB for a checked bag |
| Flight, Bangkok to Koh Samui | from about 2,300 THB, often a lot more |
| Surat Thani airport to Samui, bus and catamaran | 850–950 THB |
| Longtail, Ao Nang to Railay | 100 THB |
A three-week trip usually has five or six of these, counting the rides to and from the airport, which adds 4,000 to 7,000 baht per person. A Samui flight pushes it higher. Budget airlines sell their cheapest fares with 7 kg of cabin baggage only, so add the checked bag when you book. At the AirAsia desk the same bag is 900 baht. For each leg, the transportation guide says whether I'd take the train or fly, and 12Go shows the operators on a route side by side.
Is $3,000 enough for three weeks in Thailand?
For most people, yes, even if the flight comes out of it. These figures are per person, with travel insurance paid separately.
With the flight already paid, $3,000 is about 100,000 baht. After 6,000 or so for transport between cities, that leaves 4,500 a day for 21 days, or about 4,000 if you hold 10% back for surprises. That's more than the mid-range number, and enough for a solo traveller paying for the whole room.
If the flight comes out of the $3,000, the fare decides most of it. A $1,000 return, close to the New York average over the past year, leaves about 67,000 baht. That's 2,900 a day after transport between cities, or about 2,600 with 10% held back, the bottom of the mid-range band for two people sharing a room. On your own it means a cheaper room or fewer paid days. Every extra $100 on the fare is about 160 baht a day less once you're there.
What breaks a Thailand budget
The islands, mostly. Taxis on Phuket and Samui are run as a cartel, and even Grab prices reflect it: Chaweng to Lamai on Samui, about 10 km, is 300 to 500 baht, where the same distance in Bangkok is 140 to 180. A shared speedboat day to Phi Phi from Phuket is 1,500–3,500 baht per person, and many tours leave out the 400 baht national park fee, so ask whether it's included before you hand over cash.
A large Chang or Leo is 60 to 70 baht at 7-Eleven and 100 to 150 in a bar on a tourist street, and three bar beers a night is almost a third of a backpacker budget. Thai bank ATMs charge 250 to 350 baht per withdrawal on a foreign card, AEON's charge 150, and your own bank may add a fee on top, so I take out as much as I'm comfortable carrying in one go (more on ATMs and exchange).
Booking-site data puts September, the cheapest month, about a quarter below the yearly average and December about a third above it, with the Christmas to New Year fortnight on the islands higher still. If you're tied to the December holidays, book rooms a few months out, before the good-value ones go.
Costs before you land
A return economy fare from New York to Bangkok has averaged about $1,000 over the past year. That is about 33,500 baht, or eleven days at the mid-range rate. London is more like £450 to £850 return depending on the season, and Sydney A$900 to A$1,300 outside December. Your own dates can land well off those.
I wouldn't skip travel insurance. Basic medical cover is about $60 for up to four weeks if you're under 40, and fuller policies that cover diving and the like run $120 to $170 a month. If you're renting a scooter, read the small print, because many policies don't pay out for motorbike accidents unless you hold the right licence.
Visitors from the US, UK, Canada, Australia and most of Europe get 30 days visa-free since 15 September 2026, and the Digital Arrival Card is free on the immigration bureau's own site, whatever the copycat sites charge for it. A 450 baht tourist entry fee is planned but still needs cabinet approval and can't start before 2027. Immigration can ask to see 20,000 baht per person in cash or the equivalent, though it rarely does (the airports guide has the details). A tourist SIM is 299 baht at a 7-Eleven and 399 or more at the airport counters (SIM guide).
Working out your own number
Multiply the daily number by your days, then add the legs between cities, the flight and insurance. Hold 10% back for the boat trip or dinner you didn't plan.
One less stop is one less flight, 1,400 to 2,700 baht with a checked bag, plus the half-day you lose checking out of one place and into the next, and I'd rather put that money into a better room. If the route isn't settled yet, the trip planner shows the weather for each region on your dates.
