Orpheusuddin your question is not a very valid one. I will tell you why: Cost of living can vary greatly depending on your lifestyle. Two people living in the same city may have very different costs of living. Your question should have been: "what is your cost of living in your current city?"
As an example: me and kabir live in the same city. Our costs of living are very different. I dont spend anywhere near $1000 for gorcery in a month !!!infact I cant even think what he buys with that much money. I probably spend $250 a month on grocery !!
On the other hand when I just started working(2007) my cost of living in this same city was only $1500 a month because I was renting a room in a condo. Now I spend that much on my housing expense only ( mortgage, condo fees, property taxes).
