According to the RAC motorists in the UK spend an average of GBP 5,000 (US$ 9,000) per year on their car, or roughly 1/3 of the average net wage; while the RACV suggests roughly AUD $10,000 per year, compared to AUD $26,000 median income among all Australian adults or AUD $66,000 median income among all Australian households. This situation is reflected in most other Western nations. For the average car owner, depreciation constitutes about half the cost of running a car. The typical motorist underestimates this fixed cost by big margin, or even ignores it altogether, according to a survey by the RAC.
