Moving to Bangkok. Need information on the living costs

20000 per month rent , 1200 per month electricity, 600 per month water, 3000 per month food, 3000 per month transport more if you buy a car .

Terrymedlicott's estimates are about right i.e. "in the ballpark". My wife who is Thai and owns property in BK agrees. Then there are leisure activity costs and medical insurance, etc, to consider.  dcb

Thank you...
What all areas you would suggest (in more or less 10 kms distance to sathorn)

Medical insurance, group life insurance, etc will be provided by the company.

To what I understand, 35 - 40k baht a month should be enough to live a decent life.

I have a place way over in Prawet so I don't know Sathorn that well. Assuming you will be working in Sathorn, and not traveling a lot, you will probably want quick access to work. I did stay in a condo across the river, which is a quieter area than downtown and easy access to get to downtown over one of the bridges. Maybe if you give a more focused area of where you will be working in Sathorn, one of the members who is more in the know can give you a more specific idea. I have a friend who knows that area quite well. If nobody chimes in anytime soon, I can ask her.  Maybe you can find one of those pleasant villa type places rather than a towering condo building. It is a treat to view Bk, especially the river, from a lofty abode; but, after a few weeks you might want something closer to the ground.  dcb

Thank you, for the information.
Yes, I really would love to stay around such places as the way you explained and it should have an easy access to market to fetch household chores.

The work location would be harindhorn building, North Sathorn.
