Min 120k baht per month if you don't want to give up any comforts and still have fun. Many men living like poor men here though In tiny apartments or far from where you want to be, they do it on much much less obviously. But who wants to leave their country to live poorer than they did before.. all depends on what type of lifestyle you are used to and how you want to live .. I wouldn't recommend anyone move to any country with savings alone.. you need to be generating an income
