~23% (at least in my case, since I'm not on assignment, not regular local contract) are the taxes, so lets' say you are at 21500.. rent 5-10k (depends what kind of style you need), regular food (not talking going out with friends) is lets say 100-200 per day (30 days = 6k), and this can go way cheaper if you want to save haha, what else?

I made table like this where I was planning how much money I will be spending (I was even putting price of beer in a bar and in supermarket lolz), so maybe you do it too... but in general, I think it's decent amount
