  2. 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. The total ...

  3. Cost curve - Wikipedia

    en.wikipedia.org/wiki/Cost_curve

    In economics, a cost curve is a graph of the costs of production as a function of total quantity produced. In a free market economy, productively efficient firms optimize their production process by minimizing cost consistent with each possible level of production, and the result is a cost curve.

  4. Long-run cost curve - Wikipedia

    en.wikipedia.org/wiki/Long-run_cost_curve

    Using the long-run cost curve, firms can scale their means of production to reduce the costs of producing the good. [1] There are three principal cost functions (or 'curves') used in microeconomic analysis: Long-run total cost (LRTC) is the cost function that represents the total cost of production for all goods produced.

    1.3.1.1 Total cost function and optimal reorder point. 1.3.1.2 Normal distribution. ... The total cost is given by the sum of setup costs, purchase order cost ...

  7. Cost–volume–profit analysis - Wikipedia

    en.wikipedia.org/wiki/Cost–volume–profit...

    Total costs = fixed costs + (unit variable cost × number of units) Total revenue = sales price × number of unit These are linear because of the assumptions of constant costs and prices, and there is no distinction between units produced and units sold, as these are assumed to be equal.

  8. Economic cost - Wikipedia

    en.wikipedia.org/wiki/Economic_cost

    Average cost (AC) are total costs divided by output. AC = TFC/q + TVC/q ... It is the graphical presentation of the costs of production as a function of total ...

  9. Profit maximization - Wikipedia

    en.wikipedia.org/wiki/Profit_maximization

    This can be confirmed graphically. Using the diagram illustrating the total cost–total revenue perspective, the firm maximizes profit at the point where the slopes of the total cost line and total revenue line are equal. [4] An increase in fixed cost would cause the total cost curve to shift up rigidly by the amount of the change. [4]
