I just saw this thread and I'm like "wtf a crorepati?" lol.
The max which i had in my account was 8 lacs. Now under 10k
I'm curious, where do you live? What do you eat? The brands of clothes you wear?
Cost of living varies from one place to another. Lets take Delhi case for example. I;m going to talk from a college student's POV. In DU north campus Kamla Nagar, Guptacolony, Vijaynagar etc areas you pay a minimum of 10k for a shared PG (the food sucks btw). Now in south its around 7k for a shared PG. Now lets have a look at rent. The lowest which I've come across was 2000rs for a single-room. Take average electricity charge as 1000rs. Water fee as 500-1000max. You can save over 5k.
Most DU students say 80% of them have a very heavy lifestyle. Whats shocking is some people buy branded stuff for showing off. :| A friend of mine gets 25-30k every month but he says hes always running out of money. I have no idea how he spends all his money. I live in my uncle place so I dont pay rent but my "mess" fee comes to just about 3000-5000rs (rare case). Travelling charge? I have a student bus pass.

I dunno much about these metro-cities lifestyle but I could do with 50 grand a month somewhere else other than Mumbai, Bangalore, Delhi. Lets just say that I have a low-cost of living which is cool.
