CURRENCY & MONEY EXCHANGE

Koh Samui, like the rest of Thailand, uses the Thai Baht (THB) as its official currency. Whether you’re planning to pay for accommodation, food, shopping, or activities, it’s important to know the best ways to manage your money while on the island.

Cash is still widely used in local markets, small restaurants, and street vendors, while hotels, major stores, and upscale establishments accept credit and debit cards. ATMs and money exchange services are easily accessible, but understanding the best options can help you avoid unnecessary fees and get the best exchange rates.

Below is a detailed guide on how to exchange money, withdraw cash, use cards, and handle payments efficiently while traveling in Koh Samui.

Thai Baht (THB) – The Official Currency

  • The Thai Baht (฿ or THB) is available in:
    • Banknotes: ฿20, ฿50, ฿100, ฿500, and ฿1,000
    • Coins: ฿1, ฿2, ฿5, ฿10, and satang coins (rarely used)
  • Exchange Rate: Varies daily – check online or at exchange booths for the latest rates.
  • Currency Symbol: ฿ (Thai Baht)

💡 Tip: Carry small denominations (฿20, ฿50, and ฿100 notes) for taxis, street food, and small vendors, as they may not have change for large bills.
