Money

Thailand runs on a genuinely wide cost spread — a street-food dinner and a resort dinner can sit an order of magnitude apart within the same town. Understanding the spread matters more than memorising numbers that will be out of date by your next trip.

Cash, cards and getting money

• Cash remains essential outside cities and mid-to-upper venues — markets, songthaews, small guesthouses and rural Isaan run largely on cash;
• Cards are widely accepted in malls, chain stores and city hotels, and increasingly common elsewhere, but never assume — carry enough cash to cover a day without a card working;
• ATMs are everywhere and reliably dispense, but foreign-card withdrawal fees are a real and ongoing cost — check your own bank's foreign-transaction terms before travelling, and compare that against a specialist currency-exchange counter (common in malls and tourist areas), which can often beat both bank and airport exchange rates;
• Notify your bank of travel dates if it still asks for that, and carry a backup card kept separately from your primary one.

The honest cost curve

We deliberately don't print prices on this site — they date within months and mislead more than they help. What stays true: street food and local transport sit at the cheap end of the curve almost everywhere in the country; air-conditioned comfort, imported goods, and anything marketed at tourists sit at the expensive end; and the gap between those ends is wider in Thailand than in most travellers' home countries. Budgeting a trip well means picking, deliberately, how much of each end you want — see food literacy and where to stay for where that choice shows up most.

Tipping and service charges

Tipping isn't as embedded in Thai culture as in some countries, but it's grown common in tourist-facing hospitality — rounding up or leaving small change is well received without being obligatory. Nicer restaurants and hotels often add a service charge to the bill automatically; check before tipping on top of one.

Bargaining, done well

Bargaining belongs in markets, with unmetered transport, and for informal goods — it does not belong in malls, convenience stores, or anywhere prices are posted. Bargain with a smile, never over small amounts that matter more to the seller than to you, and stop the moment it stops being friendly. Etiquette covers the wider social rules this sits inside.

Common money mistakes, avoided

• Skipping travel insurance to save money is the costliest false economy in Thai travel — a single hospital visit or cancelled flight without cover can dwarf everything else a trip spends;
• Carrying all your cash and cards in one place undoes itself the moment a bag goes missing — split reserves between bag and person, and keep a digital record of card numbers separately;
• Assuming card acceptance at rural guesthouses, songthaews or small food stalls — check or carry cash as a default rather than a backup;
• Exchanging currency at the airport out of convenience rather than comparing it against a specialist counter once in the city, even for just the first day's cash needs.
