How much money do I need for two weeks in Thailand?
Budget roughly £700–£1,000 on the ground for two weeks in Thailand in 2026 — dorms, street food, local transport and a few activities — plus about £450–£700 for return flights from the UK. Spend big on islands, diving or nightlife and it climbs quickly; travel frugally up north and it drops.
The north (Bangkok, Chiang Mai) is cheaper than the southern islands, where beach clubs, boat trips and cocktails add up. A realistic frugal-but-fun day runs £18–£25 all in; a comfortable day with a few extras is more like £32–£45.
Flights are the single biggest variable — booking a couple of months ahead and flying midweek can save hundreds. Set aside a buffer for the things that catch people out: a dive course, a full-moon trip, or a domestic flight to skip a long bus.
