I rode my bike to work for the first time today!
Well, I rode it to the Public Transit (MARTA), and then rode the public transit to work from there. It is about 1.5 miles of biking to the train from my house.
Did I save money? well...barely
Public Transit costs $2.50 each way, so a total of $5. I bought my tickets with pre-tax money though, so I effectively saved 20% of that at my marginal tax rate right? So I spent $4 for a $5 train ride.
Vs. the Alternative:
Parking in the Area, the cheapest I've found, is $4 per day. I could buy a monthly pass though and get it down to $3 per day ($60 for a month, avg of 20 working days per month).
But in that case I would have spent money on gas too (driving is about 18 minutes and 6 miles one way, and my car gets 18 mpg or worse in the city), plus wear and tear on my tires, etc. AND, I wouldn't have gotten any exercise.
+ Gas: 12 miles roundtrip / 18 MPG = 2/3 gallon x $2.10 (price per gallon) = $1.40
+ Wear and tear, tires, oil: $.10
+ cost of no exercise
We'll call it a win!
