I am one of those nerds who keep a track of every single rupee spent. I used to do this for the 100Rs/per month pocket money which I received from my dad when I was doing my engineering and when I started to work, I just carried it forward.
From 2003 July to 2004 April, I kept track of every rupee I spent, somehow when I changed companies I lost the habit, I never kept track of things on which I spent money, I wanted to do it but found myself lazy.
Something changed in 2005 April, thats when I had to keep track of my expenses because of an offical trip, this time I had to keep the reciepts too. Thats when the excel sheet started, 10 months of data collected for official purposes. Now playing with data can be real fun, I used to spend hours just looking at graphs, on categories I spent highly on, what had changed between months, and so on.
Inbetween, when I had stopped keeping track, I used to find it miserable not knowing where the money got lost, and how come my savings showed so much less. Now that I have data, I can know where I am overspending, which one needs to come down, or whats unnecessary.
Just recently graduated to a free online tool, which eased the way I can maintain my accounts. Just love the way it allows me to play with the data.
Now, if anyone wanted proof that how big a foodie I am, here goes my last two months expense categories.
