I have some time to kill before podcast recording tonight.  I was balancing my checkbook and took a quick look at the report it generated for last year.  I noticed that all my auto expenses for last year were $2532.10.  It breaks down like this:

Fuel $839.25
Insurance $806.00
Service $545.16
Registration $222.69
Parking $99.00
Tax (tolls) $20

And since I drove for 10,400 miles last year.  I’m basically paying (253210/10400) 24.3 cents per mile.  This isn’t taking into account depreciation or cost of the car because I don’t know how to figure that.  Based on just this, each time I bike to work I’m saving 12 * 25 cents or roughly $3.  I didn’t bike that much last year, just 1082 miles.  But that’s a savings of $3246, which is kind of impressive, I think.  Makes me want to keep biking.  And I’m happy that I biked to tutoring and the library last night, even though it was 5 degrees.  It was a painful (approximate) mile to ride, but I saved myself a quarter.  🙂
