My Mileage and Money Saved By Bike Commuting

On Memorial Day I took a break from my regular bike commuting routine and drove to work.  I drove because (1) I was working on a holiday and wanted to spend as much time with my family as I could and (2) I was working especially late and did not want to have to ride home and then spend an extra hour cooling off and calming down before sleep became an option for me.  One of the benefits of the drive was that I was able to get a pretty good measurement of the actual mileage that I ride each day.

According to my 2003 Honda Odyssey I ride 14.8 miles per day.  That is 8.0 of those miles are going to work and 6.8 of those miles are coming home from work.  This was initially a surprise to me since Google Maps places my ride at 14.3 miles - but upon further analysis I decided that an error of less than 4% on a free online mapping application was not really bad at all.

Aside from letting me know the exact mileage it also helped me get an idea of my average speed - about 14 mph on the way to work and 16 mph on the way home. (The reason for the difference I am sure is the different routes and the times of day.  You catch a lot less red lights and fight a lot less traffic after 11 PM.)

Money Saved By Bike Commuting

The most important thing that I think I can gather from finding out my exact mileage is the amount of money that I am saving myself and my family by not having a second car and by biking to work.  According to the IRS, the average cost for operating an automobile is $0.50 a mile, and this is "based on an annual study of the fixed and variable costs of operating an automobile."  While I'm not sure how they determined this number, I think it is a good starting point for determining what I am saving by using my bike.

Given the $0.50 a mile standard, my average costs to travel by car would look something like this:

14.8 miles per day = $7.40 a day
74 miles per week = $32 a week
3848 miles per year = $1924 a year

Even if I do end up driving to work around 10% of the time for various reasons, the cost of driving to work is still substantial, running around $1730 a year.


I could spend $140 a  month on bike related expenses and still come out on top because I would have the added health benefits that being physically active would bring me.

The simple truth is that I have been commuting by bike for over two months now and I have not spent $280 dollars on my bike - not even close! To be sure, some serious bike expenses are forth coming - I probably should buy some new tires to have ready when my current ones wear out, I want to do a complete overhaul of my Panasonic DX 2000, and I am going to need winter gear to make it through the winter - but knowing that I could spend $1500+ on my bike over the year and still break even is pretty reassuring.

I think I plan on keeping some sort of running total of the money that I have spent year to day in the side bar so I can keep myself accountable and figure out if just how much the average beginning bike commuter is going to spend to get up and running.
