.
Normally these expenditures are divided by fixed or standing costs and variable or running costs.
Fixed costs are those ones which do not depend on the distance traveled by the vehicle and which the owner must pay to keep the vehicle ready for use on the road, like
insurance or
road taxes. Variable or running costs are those that depend on the use of the car, like

Portugal spend approximately 1/2 of their net income. For the average car owner,
depreciation constitutes about half the cost of running a car.
The typical motorist underestimates this
fixed cost by a significant margin.

the average driver of the average
sedan, spends totally approximately 8700 USD per year, or 720 USD per month, to own and operate their vehicle.
Fixed costs
Car acquisition
The car itself as a cost. The cost can be reduced by buying a reused car. But the reused car may have hidden defects, hidden problems, or be about to be out of norms. It is the most shallow and most immediate cost. But it can be delayed under a loan scheme.
Loan costs
Car finance comprises the different financial products which allows someone to acquire a car with any arrangement other than a single lump payment. When used, and for the purpose of assessing the private financial costs, one must consider only the
interests paid by the car owner, as some part of the amount the owner pays each month for the finance is already embedded in the depreciations costs.
Depreciation

The yearly
depreciation of a car is the amount its value decreases every year. Normally a car's value is correlated with the price it has on the market, but on average a car has a depreciation around 15% to 20% per year. Depending on market conditions, cars may depreciate between 10-30% the first year.
Car taxes
Car taxes,
road taxes, vehicle taxes or
Vehicle Excise Duty are the amount of money car owners pay the government to allow the car to operate within that region or state. These taxes serve to maintain the road infrastructure or to compensate the
negative externalities caused by the
motor vehicle

s. These taxes may depend on
engine displacement, vehicle weight, miles traveled,
CO2 emissions, or the car value.
Insurance
Insurance serves to provide financial protection against physical damage and/or bodily injury resulting from traffic collisions and against liability that could also arise there-from.
Inspection
Vehicle inspection is a procedure mandated by law in which a vehicle is inspected to ensure that it conforms to regulations governing safety, emissions, or both.
Driving license
A driving license is often required to drive a car.
Cost of capital
The
cost of capital
In economics and accounting, the cost of capital is the cost of a company's funds (both debt and equity), or from an investor's point of view is "the required rate of return on a portfolio company's existing securities". It is used to evaluate new ...
, applied to a purchase of a car, is the amount of money the car owner could have obtained, if they, instead of buying the car, applied that amount of money to other worthy investment. The cost of capital is the rate of return that capital could be expected to earn in an alternative investment of equivalent risk. Considering by default the car has depreciation, and that such depreciation is already considered at a certain cost item, the cost of capital of owning a car, is then the income that the car owner could have obtained with the money spent on such car. One example could be a common standard interest rate in a deposit account.
Running costs
Fuel
The fuel costs depend basically on four factors, namely the distance travelled by the car, the
price paid for the fuel, the
energy efficiency of the car and the
type of driving. In Western countries, this cost normally is the second highest after depreciation.
Maintenance
The maintenance of a car can have the purpose to be a long term or a short term maintenance. This cost might be very irregular and somewhat unpredictable but tends to increase with the age of the car. On this item are included
car parts that need to be replaced after a certain period of time (for example every two years) or with a specific number of travelled kilometres or miles, like
tires or filters.
Repairs and improvements
Repairs costs are completely unpredictable because they depend on the number and severity of car collisions, like dents repairing for example. These costs also refer to
spare part

s substitution due to malfunctioning. On this cost item it might be included also the parts bought to improve the performance or the aesthetic of the vehicle.
Parking

s. This cost might be relatively predictable, if the user for example has a monthly contract with some parking lot company, or if he rents a private parking space.
Tolls
A
toll road, also known as a turnpike or tollway, is a public or private roadway for which a fee (or toll) is assessed for passage. Normally this applies to
motorways,
bridges and
tunnels but it might also apply, like in some cities such as
London or

, to gain access to the city-centre. This cost might be predictable if the user passes the tolled roadway, a defined number of times per month.
Fines
A traffic fine or
traffic ticket is a notice issued by a law enforcement official to a
motorist accusing violation of
traffic laws. Traffic tickets generally come in two forms, citing a
moving violation, such as exceeding the
speed limit, or a non-moving violation, such as a
parking violation
A parking violation is the act of parking a motor vehicle in a restricted place or in an unauthorized manner. It is against the law virtually everywhere to park a vehicle in the middle of a highway or road; parking on one or both sides of a road ...
. These tickets almost always imply the payment of a certain quantity of money.
Car washes
The cost of
car wash varies according to the frequency users clean their car, and with the price of each cleaning.
