Filante, you wanted a monthly breakdown of costs. Here is my shot at it. I have been trying to figure this out for myself. I am moving to Singapore in late April.
Your 85K should be about 80K after taxes. Assuming 12 month pay (though 13 months, with 1 month bonus in Dec is the norm), you will have $6700 cash in hand per month. In this, your major expense categories should be:
Housing: 1800 you should get 3BR
condos in this price in out locations, close to MRT
Utilities: 250
Groceries: 800
Transport: 200
Cable/Newspaper/Internet: 150
Phone: 150
Others, including medical insurance: 500
Entertainment/discretionary: 300
Total expenses: 4200
You will be able to save about $2500 per month.
Living standards are subjective and whats great for one is not even survival for another, so I cant say if the above spending levels and assumptions will be good for you. For example, many expats cant do without a maid and car, which if added to this equation will wipe out your savings.
Hope this helps.
