Cost

In production, research, retail, and accounting, a cost is the value of money that has been used up to produce something, 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 price paid to the producer. Usually, the price also includes a mark-up for profit over the cost of production.

More generalized in the field of economics, cost is a metric that is totaling up as a result of a process or as a differential for the result of a decision. Hence cost is the metric used in the standard modeling paradigm applied to economic processes.

Costs (pl.) are often further described based on their timing or their applicability.

Famous quotes containing the word cost:

    The one regret I have about my own abortions is that they cost money that might otherwise have been spent on something more pleasurable, like taking the kids to movies and theme parks.
    Barbara Ehrenreich (b. 1941)

    One must always be aware, to notice—even though the cost of noticing is to become responsible.
    Thylias Moss, African American poet. As quoted in the Wall Street Journal (May 12, 1994)

    Keeping accounts, Sir, is of no use when a man is spending his own money, and has nobody to whom he is to account. You won’t eat less beef today, because you have written down what it cost yesterday.
    Samuel Johnson (1709–1784)
