Just a couple things to share from 2009. Specifically what I spent on gas. Trivial, sure... but I've been tracking the money I spend on gas for about 4 years now. Not sure why... just kind of like to know - that, and I like to be able to factor it into my budget.
Overall I spent $1122.21 on gas in 2009. That's down from just over $1900 in 2008 and well over $2000 in 2007. I'm certainly driving a lot less lately - except the summer is still busy. For a while a couple years ago I was spending up to $200 a month in gas... or more! Lately I've been under $100. Of course... it's nice to be only 3 miles from work (one way) but Jen and I also split the driving between each car - so that helps too - she drives less than I do still though.
Just because I'm kind of anal about some of these things, here are a couple graphs for you. The first one is just the last few years overall. The second is my monthly average for the same time period.
I can't expect to come down much more in 2010, but I'd like to stay right around where I was for 2009. I'll be happy with that.
