In brief: they are significantly less than living with one.

We don’t even need to park the bike at our son’s summer camp. Matt just rides into the middle of the field to pick him up. The other kids were so jealous.
I wrote earlier about the monthly costs of keeping our minivan ($400-$600/month), but I realized I forgot one expense: parking. Parking for one car is included in our rent at home, and although the market value of that space is ~$250/month, we’re not allowed to rent it if we don’t use it so it’s a wash. But whenever we drove the minivan anywhere else, we almost always had to pay to park. Our weekday driving primarily came when Matt drove to work because he was going out of the city for business. However, even though he’s not normally a car commuter, if he stopped at the office before or after, paying for parking was his responsibility. Because hey, it was just his normal commute, right? The same was true for me. The cost of parking where we work is $15-$20 per day. It worked out to between $50-$100 per month, conservatively. Plus on the weekends we had to feed meters. So the cost of owning the car was really somewhere between $450-$700/month, depending on how much we drove. It shocks me just writing those numbers. And we owned the minivan outright, so no car payments in that calculation. (If you ignore depreciation and only count actual out-of-pocket expenses it was still $250-$500/month.)
This is still better than when we were car commuting and paying $140/month for a campus parking permit on top of the occasional downtown parking. My god, that car was expensive! No wonder Uber is making a killing in San Francisco. I could take daily limo rides without running up a $600-$850 monthly tab (or $400-$650 ignoring depreciation again).
Anyway, now that Matt has to rent a car for his business trips, the company pays for parking the rental car at the office, because he obviously wouldn’t be driving a rental car on his regular commute. Ha. Ha ha.

My son, passed out on my lap on Muni. (The Brompton continues to reign supreme in practicality; there was only space on the bus bike rack for one more bike–my son’s.)
In this first car-free month I was curious how much alternative transportation would cost us. It was a weird month. Matt had a series of meetings in the South Bay, so got a rental car for one week through work. By coincidence that was the same week that his mother went in for brain surgery in Redwood City, so there was a lot of extra driving to see her on top of those meetings. And we took a long BART ride one weekend to visit her in Berkeley after she went home. What can I say? We worry. We had planned to rent a car (and will next time we go; the round trip on BART is 4+ hours) but the San Francisco Marathon shut down the city. The MinUte went back to the bike shop while the N-Judah line was under construction, so we tried out ride sharing one weekend. And our son had a week of bike camp across town when Matt was away, which given the need to carry his bike implied a couple of trips using car share as well–we tried it once on Muni but (a) it’s so slow that we were late and the camp called us wondering where he was and (b) he was exhausted all day after riding over from the bus stop. And then the mamachari died.
I realize that every month is unique in its own way, but ironically, we drove more in July without a car than in any of the previous three months when we actually owned one. However no one else we know has brain surgery plans and the N-Judah is back in business, so this was probably an expensive month by the standards of car-free life, although having our bike collection radically thinned isn’t helping. Overall I hope that the next few months are much less exciting regardless of cost. (Matt’s mom is fine, by the way, although her surgery would have been better timed around Halloween, when she could have gotten some serious mileage out of the staples ringing her scalp. Oh well, hindsight.)
So our transportation costs for the month (rounded up to whole numbers):
- fares for extra Muni and BART rides: $44
- City CarShare rentals, meter parking, and Lyft ride: $48
- maintenance on the Kona MinUte (bent derailleur repair): $24
- rental car through work (including parking): $0 for us!
The total damage (for a very heavy month of auto travel by our standards even without the rental car through work): $116. Seriously? And we actually drove more than usual? Well hello, college savings. Even if we didn’t own bikes and took car share, ride share and Muni everywhere, we’d still save money by not owning a car. I am still sideswiped by disbelief. No pun intended.
I love these kinds of calculations. In January I took my car in for service. I had only driven 5,000 miles in two years and the guys working there were amazed and probably disappointed since the $$ I would have spent there if I were a normal car owner would have been a lot more. http://ladyfleur.wordpress.com/2012/01/31/calculating-the-cost-of-car-ownership/
Bummer that they won’t let you rent out the unused parking spot at your house. I imagine that’s to keep people from renting it out and then cluttering the street.
That’s impressively low mileage on your car. We drove more because of Matt’s work-related travel. At the point our mileage dropped to an estimated ~5k annually, the cost of insurance alone started to make renting cars exclusively look more practical.
Not being able to rent the space is partly about street parking but mostly about security. They university is obsessed with limiting access to its buildings and draconian about keys and garage door openers. I am actually pretty okay with that.
Auto insurance for the dodge caliber in this town with a spotless driving record was $200/month alone. We were spending approx $650/month for transportation without making car payments. Our first month without a car, we spent $350 for transportation. That’s almost half and that doesn’t include the license plate and repairs etc…
Wow, I will stop complaining about the cost of auto insurance here now that I know how much you were paying!
