    Marginal cost: The increase in cost caused by an additional unit of production is called marginal cost. By definition, marginal cost (MC) is equal to the change in total cost ( TC) divided by the corresponding change in output ( Q): MC(Q) = TC(Q)/ Q or, taking the limit as Q goes to zero, MC(Q) = lim( Q→0) TC(Q)/ Q = dTC/dQ.

  3. Marginal cost - Wikipedia

    en.wikipedia.org/wiki/Marginal_cost

    In economics, the marginal cost is the change in the total cost that arises when the quantity produced is increased, i.e. the cost of producing additional quantity. [1] In some contexts, it refers to an increment of one unit of output, and in others it refers to the rate of change of total cost as output is increased by an infinitesimal amount.

  4. Cost accounting - Wikipedia

    en.wikipedia.org/wiki/Cost_accounting

    Marginal costs: The marginal cost is the change in the total cost caused by increasing or decreasing output by one unit. Differential costs: This cost is the difference in total cost resulting from selecting one alternative over another. Opportunity costs: The value of a benefit sacrificed in favour of an alternative course of action.

  5. What is Opportunity Cost? - AOL

    Opportunity cost is also often defined, more specifically, as the highest-value opportunity forgone. So let's say you could have become a brain surgeon, earning $250,000 per year, instead of a ...

    Opportunity cost is a basic microeconomics concept, maybe one you learned in a long-ago and hazily recollected 8 a.m. Econ 101 lecture. If you need a refresher, opportunity cost is the benefit you ...

  7. Total cost - Wikipedia

    en.wikipedia.org/wiki/Total_cost

    The additional total cost of one additional unit of production is called marginal cost. The marginal cost can also be calculated by finding the derivative of total cost or variable cost. Either of these derivatives work because the total cost includes variable cost and fixed cost, but fixed cost is a constant with a derivative of 0.

  8. Diminishing returns - Wikipedia

    en.wikipedia.org/wiki/Diminishing_returns

    Similarly, if the third kilogram of seeds yields only a quarter ton, then the marginal cost equals per quarter ton or per ton, and the average cost is per 7/4 tons, or /7 per ton of output. Thus, diminishing marginal returns imply increasing marginal costs and increasing average costs. Cost is measured in terms of opportunity cost. In this case ...

  9. Managerial economics - Wikipedia

    en.wikipedia.org/wiki/Managerial_economics

    Production costs directly affect a firm's profitability. In order to maximise profits, firms identify the cost minimising output level for a firm where marginal cost equals marginal revenue. The most common types of costs that are factored into this decision include: [89] Fixed costs; Variable costs; Marginal cost; Average total cost; Sunk costs
