While Thailand is known for being a fairly cheap country for travellers, many people can be surprised by how quickly their funds run short, especially if they move around a lot or spend a lot of time in popular cities and island resorts.
The current exchange rate is 1 GBP to 43.24 THB, or 1 USD to 33.25 USD.
Solo travellers who stay in dorms, eat in local restaurants or from street food vendors, use local transportation, and don’t splash out on tours and expensive attractions can comfortably travel with a budget of around 750 Thai baht per day. Increasing the budget to 1,000 THB (£20-£25) per day allows for a few little extras, such as the occasional beer in the evening or small souvenirs.
Of course, travellers get more for their money in less touristy destinations. Additionally, Northern Thailand is slightly less expensive than Southern Thailand and the capital of Bangkok. It is, therefore, more cost effective to explore places like Chiang Mai and Chiang Rai than to laze on a lounger in Phuket or Koh Samui.
