Superrich and similar exchange booths usually give the best rates in the country. The two big orange- and green-branded chains — Superrich Thailand and Superrich 1965 — are separate companies with branches near BTS stations and in malls across the city; independent booths in tourist areas like Sukhumvit and Silom are often competitive too. It's worth comparing two or three boards before you commit, since rates can vary noticeably between operators on the same street.

Banks offer decent, if slightly worse, rates than the best exchange booths. You'll typically need to show your passport for larger amounts.

Airport counters at Suvarnabhumi and Don Mueang have by far the worst rates — often 5–10% below what you'd get in the city. Only exchange enough there to cover the taxi or train into town, and do the rest once you've arrived — the airport-to-city guide has what that ride costs from each terminal, so you know how little that is.

One more tip: larger banknotes (like $100 bills or €50/€100 notes) generally get a better rate per unit than small, worn, or older-series bills.

Almost every Thai bank now charges foreign cards a flat fee for each withdrawal — commonly around 220 THB, on top of whatever your own bank charges for a foreign transaction. Because that fee doesn't change with the amount withdrawn, it pays to make fewer, larger withdrawals rather than pulling out small amounts every day or two.

Some travel-focused debit cards (multi-currency accounts like Wise or Revolut, for example) reimburse ATM fees or skip foreign transaction fees entirely — worth setting one up before your trip if you'll be withdrawing often.

Whenever an ATM (or a card machine in a shop) asks whether you'd like to be charged in your home currency or in THB, always choose THB. Accepting the foreign-currency option — known as Dynamic Currency Conversion — locks in a marked-up exchange rate that's almost always worse than your own bank's rate.

Cards are widely accepted at hotels, malls, chain restaurants and supermarkets, and contactless payment (including Apple Pay and Google Pay) works at most modern retailers and even many 7-Eleven branches.

Street food stalls, local markets, songthaews, and small family-run shops are usually cash-only, so keep a supply of smaller notes — 20, 50 and 100 THB bills — handy for everyday spending.

A practical mix: put bigger purchases and hotel bills on a card with low or no foreign transaction fees, and carry cash for markets, street food and taxis. For how much of that to draw in a week, the trip budget calculator works a daily figure out of the prices we hold for our own listings, and street food: what to order gives the 2026 price band for a plate.
