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 cost of producing a specific level of output is the cost of all the factors of production.
The total cost curve, if non-linear, can represent increasing and diminishing marginal returns.. The short-run total cost (SRTC) and long-run total cost (LRTC) curves are increasing in the quantity of output produced because producing more output requires more labor usage in both the short and long runs, and because in the long run producing more output involves using more of the physical ...
The break-even point (BEP) or break-even level represents the sales amount—in either unit (quantity) or revenue (sales) terms—that is required to cover total costs, consisting of both fixed and variable costs to the company. Total profit at the break-even point is zero. It is only possible for a firm to pass the break-even point if the ...
These diagrams can be related by a rather busy diagram, which demonstrates how if one subtracts variable costs, the sales and total costs lines shift down to become the contribution and fixed costs lines.
If producing 5 shirts generates an average total cost of 11 dollars and average variable cost of 5 dollars, the fixed cost would be 6 dollars. Similarly, the firm produces 10 shirts and average total cost and average variable cost is 10 dollars and 7 dollars respectively. In this case, the average fixed cost would be 3 dollars.
When some costs are sunk and some are not sunk, total fixed costs (TFC) equal sunk fixed costs (SFC) plus non-sunk fixed costs (NSFC) or TFC = SFC + NSFC. When some fixed costs are non-sunk, the shutdown rule must be modified. To illustrate the new rule it is necessary to define a new cost curve, the average non-sunk cost curve, or ANSC.
To do this, draw the total cost curve (TC in the diagram), which shows the total cost associated with each possible level of output, the fixed cost curve (FC) which shows the costs that do not vary with output level, and finally the various total revenue lines (R1, R2, and R3), which show the total amount of revenue received at each output ...
Along with variable costs, fixed costs make up one of the two components of total cost: total cost is equal to fixed costs plus variable costs. In accounting and economics, fixed costs, also known as indirect costs or overhead costs, are business expenses that are not dependent on the level of goods or services produced by the business. They ...
