(www.consumerreports.org) Consumer Reports has a comprehensive cost of ownership model with lots of interesting charts to get lost in. Up front they claim the median car costs $9,100 per year to own, but there are plenty of nice cars that cost less. Their breakdown is:

  • Depreciation
  • Fuel
  • Interest (on the loan)
  • Insurance
  • Maintenance and Repair
  • Taxes (and other fees)

Another way to divide the costs is into:

  • Carrying costs:- Costs associated with vehicle purchase, like the interest on the loan
  • Operating costs:- Costs associated with ongoing ownership, like fuel and maintenance

Carrying costs fall dramatically over time, while the operating costs tend to go upward. That is, the insurance or taxes on an old car is cheaper than a new car, and you will have paid off the loan after a few years. On the other hand, as a car ages repair costs go up.

(www.edmunds.com) Edmunds has a guide on keeping car expenses to a budget, that has a nice discussion of cost of ownership. They recommend car expenses stay within 20% of total (before tax) wages.

  • Taxes & Fees – 8%
  • Finance & Interest – 12%
  • Insurance – 25%
  • Fuel costs – 41%
  • Maintenance – 11%
  • Repairs – 3%
