TL;DR:Expect roughly 40,000–60,000 THB/month in Bangkok, 20,000–35,000 THB in Chiang Mai, and 15,000–25,000 THB in smaller cities; add 10–20% as a buffer and more for a higher standard of living.
Budget depends on city and lifestyle. For a single adult living long-term in Thailand (basic breakdown: rent, utilities, food, transport, health insurance, misc), typical monthly ranges are:
- Bangkok (1‑bed in a central or convenient area): total 40,000–60,000 THB (~US$1,150–1,700).
- Chiang Mai / midsize city (1‑bed, good area): total 20,000–35,000 THB (~US$570–1,000).
- Smaller city or provincial town (simple 1‑bed, local lifestyle): total 15,000–25,000 THB (~US$430–720).
Those totals include modest private health insurance (1,000–4,000 THB/month) but exclude one‑off relocation, visa fees, international school fees, or major medical care. If you prefer more comfort (larger apartment, dining out, private schools) add 30–80% to these figures. Use a 10–20% safety buffer for exchange-rate swings and unexpected costs. For local rental and healthcare benchmarks see Thailand guides on rentals and healthcare.
