Life / What is the cost of living per month for a single expat in Warsaw? [19]

Hi All,

What is the cost of living per month for a single expat in Warsaw from India. Considering I do not drink and don't go to pubs, will cook by myself, will rent 1 room apartment (studio apartment) and with basic lifestyle.

Please provide some realistic numbers to decide if I should at all move to Warsaw:
1. Apartment rent
2. Public transportation (monthly pass)
3. Vegetables and chicken (monthly)
4. Grocery (monthly)

Again, what are the types of deductions from salary like tax and all, and what percent each one is.

Please help me with some realistic numbers so that I can decide whether to relocate to Warsaw, Poland or not.

Thanks in advance
