that has been used up to produce something or deliver a service, and hence is not available for use anymore. In business, the cost may be one of acquisition, in which case the amount of money expended to acquire it is counted as cost. In this case, money is the input that is gone in order to acquire the thing. This acquisition cost may be the sum of the cost of production as incurred by the original producer, and further costs of transaction as incurred by the acquirer over and above the

Opportunity cost, also referred to as ''
economic cost'' is the value of the best alternative that was not chosen in order to pursue the current endeavor—i.e., what could have been accomplished with the resources expended in the undertaking. It represents opportunities forgone.
In theoretical economics, cost used without qualification often means opportunity cost.
Comparing private, external, and social costs
When a transaction takes place, it typically involves both private costs and external costs.
Private costs are the costs that the buyer of a good or service pays the seller. This can also be described as the costs internal to the firm's
production function.
External costs (also called externalities), in contrast, are the costs that people other than the buyer are forced to pay as a result of the transaction. The bearers of such costs can be either particular individuals or society at large. Note that external costs are often both non-monetary and problematic to quantify for comparison with monetary values. They include things like pollution, things that society will likely have to pay for in some way or at some time in the future, even so that are not included in transaction prices.
Social costs are the sum of private costs and external costs.
For example, the manufacturing cost of a car (i.e., the costs of buying inputs, land tax rates for the car plant,
overhead costs of running the plant and labor costs) reflects the ''private cost'' for the manufacturer (in some ways, normal profit can also be seen as a cost of production; see, e.g., Ison and Wall, 2007, p. 181). The polluted waters or polluted air also created as part of the process of producing the car is an ''external cost'' borne by those who are affected by the pollution or who value unpolluted air or water. Because the manufacturer does not pay for this external cost (the cost of emitting undesirable waste into the commons), and does not include this cost in the price of the car (a
Kaldor–Hicks compensation), they are said to be external to the market pricing mechanism. The air pollution from driving the car is also an externality produced by the car user in the process of using his good. The driver does not compensate for the
environmental damage caused by using the car.
