Money Matters in Thailand: Practical Tips for ATMs, Tipping, and Local Currency

Thailand is one of Southeast Asia’s most visited countries, and for good reason — the food, temples, beaches, and street life are extraordinary. But the financial side of travel here trips up even experienced travelers. ATM fees are steep, tipping norms are genuinely confusing, and a poorly timed currency swap can cost you more than a night’s accommodation. This guide cuts through the noise with specific, practical advice on handling money in Thailand — from the moment you land to your last baht spent.

The Thai Baht — Denominations, Coins, and What to Know Before You Land

The official currency is the Thai Baht (THB), abbreviated as ฿. As of mid-2025, the exchange rate hovers around 35–36 THB to 1 USD, though this shifts regularly. It’s worth checking xe.com or Google the morning you plan to exchange money so you know exactly what a fair rate looks like.

Banknotes come in six denominations: ฿20 (green), ฿50 (blue), ฿100 (red), ฿500 (purple), and ฿1,000 (beige/tan). There’s also a rarely seen ฿10 note. Coins include ฿1, ฿2, ฿5, and ฿10, with the ฿10 coin being distinctive — it has a gold outer ring and silver center. Don’t be surprised when street food vendors, tuk-tuk drivers, and market stalls give you handfuls of coins in change. They’re worth keeping rather than tossing aside, since small purchases add up quickly.

One important cultural note: Thai banknotes feature the King’s image, and Thai law treats disrespectful handling of currency very seriously. Don’t fold, step on, or crumple notes carelessly in public. It sounds extreme, but this is a country where lèse-majesté laws carry real consequences.

Before you travel, resist the temptation to order baht from your home bank. Rates from international banks for pre-ordered foreign currency are almost universally poor. You’ll do far better exchanging money in Thailand itself — whether at an ATM or a dedicated exchange booth.

ATMs in Thailand — Fees, Card Skimming Risks, and the Best Machines to Use

Every ATM in Thailand charges foreign cardholders a flat withdrawal fee. Since 2017, this fee has been standardized across most banks at ฿220 per transaction (roughly $6–$6.50 USD). A handful of banks charge ฿200, but ฿220 is the norm. On top of this, your home bank will likely add its own foreign transaction fee — typically 1–3% of the withdrawal amount.

The math matters: if you withdraw only ฿2,000 at a time ($55), that ฿220 fee represents a 10%+ surcharge. Withdraw ฿10,000 instead ($277), and the percentage drops below 2.5%. Always withdraw the maximum your card allows per transaction, and check your bank’s daily ATM limits before you travel.

In terms of which banks to use:

• Kasikorn Bank (KBank) — green machines: Widely considered the most reliable and least prone to technical issues with foreign cards.
• Bangkok Bank: Also solid and widespread, especially useful in smaller towns.
• Aeon Bank: Often found in malls and Big C supermarkets. They only charge ฿150 per transaction in some locations — worth seeking out if you find one.
• SCB (Siam Commercial Bank): Reliable and common in tourist areas.
• Avoid independent/white-label ATMs: Machines inside convenience stores or standalone units not affiliated with a major bank have higher skimming risks and often worse rates.

On card skimming: it’s a real risk, particularly in high-tourist areas like Pattaya, Phuket, and Khao San Road. Before inserting your card, jiggle the card slot — if it moves or feels loose, find another machine. Cover the keypad with your hand when entering your PIN. Use ATMs inside bank branches during business hours when possible, since these are monitored and less frequently tampered with.

Notify your bank before traveling so your card isn’t frozen on first use. Also confirm whether your card charges foreign transaction fees at all — cards like Charles Schwab’s debit card or Wise’s card reimburse ATM fees globally, which is a significant saving over two weeks in Thailand.

Currency Exchange — Where to Swap, Where to Avoid, and the SuperRich Secret

The best exchange rates in Thailand come from independent money changers, not banks or airport booths. The gap can be meaningful — sometimes 1–2 baht per dollar, which on a $500 exchange amounts to ฿500–฿1,000 lost for no reason.

The gold standard for exchange booths is SuperRich Thailand. There are two separate companies with similar names — the original SuperRich (orange) and SuperRich 1965 (green). Both offer rates that are consistently better than airport counters and most banks. They have branches across Bangkok, including in major malls like CentralWorld and along Silom Road. Their rates are posted clearly and updated throughout the day. No commission, no hidden fees — what you see is what you get.

Other reliable independent changers include Vasu Exchange in Bangkok and various licensed exchange booths found near popular tourist areas in Chiang Mai’s Old City. Always look for booths displaying the Bank of Thailand license — a small sign with “Authorized Money Changer” — which indicates government oversight.

Places to avoid:

• Suvarnabhumi and Don Mueang airports: Rates are 1.5–2.5 baht per dollar worse than city exchanges. Change only the minimum you need to get into town — ฿500–฿1,000 for a taxi, SIM card, or snack.
• Hotel front desks: Convenient but almost always terrible rates.
• Bank branches for cash exchange: Thai banks apply spread rates that are worse than licensed money changers, plus they often charge a fee per transaction.

Timing matters too. Exchange rates fluctuate during the day. SuperRich and similar changers typically post better rates in the morning. If you’re exchanging a large sum, it’s worth checking rates across two or three booths in the same area — they’re often clustered together and competition keeps them honest.

Paying by Card — Where It Works, Where It Doesn’t, and Dynamic Currency Conversion Traps

Credit and debit cards are widely accepted in Thailand’s malls, mid-range and upscale restaurants, chain hotels, and large retail stores. Visa and Mastercard are universally recognized; American Express is hit-or-miss. However, much of the daily economic life — street food, local markets, independent guesthouses, tuk-tuks, songthaews, and small family-run restaurants — operates entirely in cash.

A useful rule of thumb: if the menu has photos laminated in plastic, cash is expected. If there’s a printed wine list, they probably take cards.

The biggest card-related trap in Thailand is Dynamic Currency Conversion (DCC). When you pay by card, the terminal sometimes asks whether you want to be charged in Thai Baht or your home currency (USD, GBP, EUR, etc.). Always choose Thai Baht. When a merchant converts to your home currency on the spot, they apply their own exchange rate — typically 3–7% worse than your bank’s rate. Your bank’s rate, despite any foreign transaction fee, is almost always better. This applies to ATMs too — if an ATM asks whether you’d like to proceed “with conversion” or “without conversion,” choose without conversion (i.e., in Thai Baht).

Some restaurants and shops in heavily touristed areas have started defaulting the terminal to DCC without clearly informing you. Watch the screen before you tap or insert your card, and ask staff to switch it to baht if needed. They can do this — it just requires a reset of the transaction.

Tipping Culture — Who to Tip, How Much, and Who Genuinely Expects Nothing

Tipping is not historically embedded in Thai culture the way it is in the United States, but tourism has significantly changed expectations — particularly in cities and resort towns. The picture is more nuanced than either “tip everyone” or “tipping isn’t done here.”

Here’s a practical breakdown:

• Sit-down restaurants (tourist areas): A tip of ฿20–฿50 per person is appreciated. If the bill comes to ฿600, leaving ฿50–฿100 is generous and appropriate. Staff in tourist-oriented restaurants often earn low base wages with tips expected to supplement income.
• Upscale restaurants with a service charge: Many add a 10% service charge to the bill automatically. Check before tipping — the line item will say “service charge.” That said, this charge often goes to the restaurant rather than directly to staff, so a small additional cash tip (฿50–฿100) is still kind.
• Street food and local eateries: No tip expected. Leaving coins is fine but not customary. These vendors price their food to make a living — a bowl of noodles at ฿50 doesn’t require supplementing.
• Massage and spa workers: Tip ฿50–฿100 for a traditional Thai massage (usually 1–2 hours). For a higher-end spa treatment, ฿100–฿200 is appropriate. This is one of the situations where tips are most genuinely appreciated and expected.
• Hotel housekeeping: Leave ฿20–฿50 per day in an obvious spot. In luxury hotels, ฿50–฿100 is reasonable.
• Taxi drivers: Not mandatory, but rounding up to the nearest ฿10 or ฿20 is a simple courtesy. For a ฿85 fare, handing over ฿100 and saying “keep the change” is perfectly normal.
• Tour guides: For a private guide, ฿200–฿500 per person per day depending on the length and quality of the tour. Group tour guides: ฿100–฿200 per person is customary.
• Tuk-tuk drivers: No standard tip expected since prices are negotiated upfront. If a driver was particularly helpful or entertaining, rounding up generously is a nice gesture.

Always tip in cash, directly to the person. Cards don’t work for this, and in group restaurant settings, tip lines on receipts often don’t reach the server.

Bargaining and Cash Etiquette — Markets, Tuk-Tuks, and Unspoken Rules

Bargaining is expected at markets, from tuk-tuk drivers for unmetered journeys, and with independent vendors — but it has a code of conduct that most tourists get wrong.

In night markets like Chatuchak in Bangkok or the Sunday Walking Street in Chiang Mai, the first quoted price for a souvenir or clothing item is almost always 30–50% above what the vendor expects to accept. Starting your counter-offer at 50–60% of the asking price is reasonable. But keep the tone light and friendly — bargaining is a social exchange, not a confrontation. If the vendor laughs and comes down slightly, you’re in a negotiation. If they look genuinely offended, you may have underbid on something that was already fairly priced.

Walk away when it suits you. Vendors will often call you back with a better price. This works especially well in the late evening when vendors are trying to close out their stock. The moment when you physically start to leave is often when the real final price appears.

Bargaining is not appropriate in the following situations:

• Restaurants and food stalls (prices are fixed)
• Official stores, chain retailers, or anywhere with printed price tags
• Metered taxis — insist on the meter for all metered taxi rides
• Entry fees to temples or national parks

One cash etiquette note worth knowing: when handing money to someone, use both hands or your right hand with your left hand lightly touching your right forearm. This shows respect. It’s not strictly required in every cash transaction, but in a country where small gestures of politeness carry real weight, it lands well.

Scams and Money Mistakes — The Classic Traps Targeting Tourists

Thailand’s tourism infrastructure is excellent, but a handful of money-related scams are so persistent they’ve become clichés — and tourists still fall for them constantly.

The closed attraction gambit: A friendly stranger (often near a major temple) tells you it’s closed for a special ceremony, but offers to take you somewhere better by tuk-tuk. The tuk-tuk driver gets paid a commission to bring you to overpriced gem shops or tailor shops. The temple is almost never actually closed. Ignore unsolicited route advice from strangers near major attractions.

Taxi flat rate scams: Drivers near airports, train stations, and tourist areas often refuse to use the meter and quote a flat rate instead. In Bangkok, metered taxis are almost always cheaper — insist on the meter or use Grab (the regional equivalent of Uber), which shows the fare upfront.

Gem and gold investment scams: A variation of the tuk-tuk gambit. You’re taken to a jewelry or gem shop with promises of incredible deals or “government sales.” Gems purchased in these scenarios are routinely overvalued or fake. This scam has been running for decades and continues to work because the social engineering is good.

The wrong change trick: In busy markets and street stalls, vendors may hand back change quickly and confidently, hoping you don’t notice you’ve received less than owed. Count your change every time. There’s no social awkwardness in doing so — vendors expect it.

ATM “help”: If a stranger approaches while you’re at an ATM offering to “help” with a machine problem or error, decline and walk away. Real bank employees don’t do this. Skimming device installation is sometimes paired with distraction techniques.

The most effective protection against all of these is simply slowing down. Most financial mistakes in Thailand happen when travelers are tired, rushed, or trying to be polite. Taking an extra ten seconds to count change, confirm a fare, or read an ATM screen before pressing “confirm” is worth more than any travel insurance add-on.
