Thanks Painther and Gduck for these details..

@ painther

to be specific on what i meant by entertainment - eating out couple of times, a movie and couple of visit to malls etc..

is there any other major expense i need to consider?

Ofcourse my aim would be to save money , but also not to be frugal

@ bijuabraham

I agree that each one of us has a different living style and nature of expense, the aim of the query was to understand a midway (neither frugal nor luxurious) so that i could make a fair estimate. Thanks
