The Thai baht is Thailand’s official currency and will be the unit you use for almost every purchase while in the country. This guide explains how the baht is structured, how people typically obtain it, and practical advice visitors report useful when handling money in Thailand.
What the Thai baht is and a brief history
The baht serves as the national currency of Thailand and is divided into 100 smaller units called satang. Modern banknotes and coin denominations are the standard medium for transactions across the country.
Historically, the area that is now Thailand relied on a range of very different exchange items before standardized coinage and paper money. Archaeological and historical accounts note the use of shells and clay tokens; a distinctive local form of coin known as pot duang was also common. Paper money appeared in the mid-19th century, with a note type introduced in 1853 under King Mongkut. Later reforms during the reign of King Chulalongkorn brought further changes to the country’s currency system, and in 1902 the baht was established as the formal national currency alongside new government minting and finance institutions.
Key features: denominations, coins and banknotes
One baht equals 100 satang. The series of banknotes currently issued includes 20, 50, 100, 500 and 1,000 baht notes. Coins commonly seen in circulation include 1, 2, 5 and 10 baht, plus smaller 25 and 50 satang coins. These denominations cover everyday purchases from street vendors up to larger services and retail.
Card acceptance is widespread in modern hotels, shopping centres and many restaurants, but cash remains necessary for markets, small eateries and local transport. For guidance on where to dine in Bangkok where card payments are typical, visitors often consult reviews of upscale restaurants that note payment options alongside menus.
- Banknotes: 20, 50, 100, 500, 1000 baht
- Coins: 25, 50 satang; 1, 2, 5, 10 baht
Practical tips for getting and handling baht
Travelers obtain baht in several ways: exchanging currency at banks or specialised counters, using airport exchange booths, withdrawing from ATMs, or in rarer cases using traveller’s cheques. Banks are often recommended for competitive rates. Airport counters may be convenient and sometimes offer reasonable rates compared with city kiosks. Many visitors report ATM withdrawal fees of around 150 THB per transaction when using foreign cards; this can vary by bank and card provider.
Exchanging larger sums at once can reduce per-transaction costs, so some travellers prefer to change a substantial amount on arrival rather than many small transactions. Historically reported exchange rates are useful for orientation but fluctuate; for example, in May 2020 common mid-market rates were approximately 1 USD = 32.6347 THB, 1 EUR = 35.7671 THB, 1 GBP = 41.0873 THB, 1 IDR = 0.429291 THB and 1 AUD = 20.9026 THB. Keep in mind these figures are from May 2020 and exchange values change over time.

- Withdraw larger amounts when possible to reduce repeated ATM fees.
- Carry some small notes and coins for markets and street food vendors.
- Use bank exchange counters for potentially better rates than tourist kiosks.
Cultural context and currency etiquette
Certain behaviours involving Thai currency can offend local sensibilities. Notes and coins that show the image of the Thai monarch are treated with respect; deliberately stepping on or sitting on money that bears the king’s portrait is viewed as disrespectful. Visitors are advised not to deface or deliberately damage banknotes.
Pickpocketing can occur in crowded areas, so travellers typically keep cash in a secure, front-facing bag or a money belt rather than in a back pocket. Tipping is not mandatory in Thailand; many visitors leave small change or a modest amount such as 5–20 THB for casual services if they wish to show appreciation, but it’s left to personal discretion.
- Keep bills flat and intact — don’t tear or mark notes.
- Store cash in a secure, front-facing pouch to reduce theft risk.
- Tipping is voluntary; small amounts are common for good service.
Who the baht matters most to and common use cases
The baht is essential knowledge for short-stay tourists, long-term visitors and expatriates living in Thailand. Day-to-day shopping, eating at local food stalls, paying taxi drivers, and buying train or bus tickets are typically conducted in baht cash. Longer-term residents will also need to use baht for rent, utilities and other recurring expenses.
For short visits, visitors often budget modest daily amounts for basic needs—many reports suggest a simple day’s expenses (water, a basic meal and local transport) can range from roughly 250–300 THB depending on location and choices. Those planning nightlife, shopping or spa treatments should budget more accordingly.
- Short-stay tourists: focus on carrying smaller notes and coins for street purchases.
- Long-term visitors: set up local banking to manage larger bills and recurring costs.
- Budget travellers: plan daily cash needs and be mindful of ATM fees.
