It’s about 45k Baht a month for full singles pension you get some additional supplements if living in the country. You have to remain in the country for the first 2 years of the pension after that it is full portable depending on how many years you worked for. 37 years gives you the full amount out of country. Anything less is paid prorata if you only worked for 25 years then you would only get 25/37 out of country.
