Average cost curves are typically U-shaped, as Figure 1 shows. Average total cost starts off relatively high, because at low levels of output total costs are dominated by the fixed cost; mathematically, the denominator is so small that average total cost is large.
Average total cost then declines, as the fixed costs are spread over an increasing quantity of output. In the average cost calculation, the rise in the numerator of total costs is relatively small compared to the rise in the denominator of quantity produced. But as output expands still further, the average cost begins to rise. At the right side of the average cost curve, total costs begin rising more rapidly as diminishing returns kick in. Figure 1. Cost Curves at the Clip Joint.
The information on total costs, fixed cost, and variable cost can also be presented on a per-unit basis. Average total cost ATC is calculated by dividing total cost by the total quantity produced. The average total cost curve is typically U-shaped. Average variable cost AVC is calculated by dividing variable cost by the quantity produced. The average variable cost curve lies below the average total cost curve and is typically U-shaped or upward-sloping.
Marginal cost MC is calculated by taking the change in total cost between two levels of output and dividing by the change in output. The marginal cost curve is upward-sloping. Average variable cost obtained when variable cost is divided by quantity of output. Note that at any level of output, the average variable cost curve will always lie below the curve for average total cost, as shown in Figure 1.

Variable costs are costs that do vary with output, and they are also called direct costs. Examples of typical variable costs include fuel, raw materials, and some labour costs. Consider the following hypothetical example of a boat building firm. Total variable costs TVC will increase as output increases.
Given that total fixed costs TFC are constant as output increases, the curve is a horizontal line on the cost graph. The total variable cost TVC curve slopes up at an accelerating rate, reflecting the law of diminishing marginal returns. The total cost TC curve is found by adding total fixed and total variable costs. Its position reflects the amount of fixed costs, and its gradient reflects variable costs. Average fixed costs are found by dividing total fixed costs by output. As fixed cost is divided by an increasing output, average fixed costs will continue to fall.
The average variable cost AVC curve will at first slope down from left to right, then reach a minimum point, and rise again. The resources given up are expressed in monetary terms. Rent expense is a type of fixed operating cost or an absorption cost for a business, as opposed to a variable expense. Rental expenses are often subject to a one- or two-year contract between the lessor and lessee, with options to renew.
As raw material costs change along with production volumes, they are considered to be variable costs. Direct costs are costs related to a specific cost object. A cost object is an item for which costs are compiled, such as a product, person, sales region, or customer. Examples of direct costs are consumable supplies, direct materials, sales commissions, and freight. Direct costs are attributable to a specific product, department, goods, or service.
On the other hand, indirect costs are attributable to multiple products or services. Direct costs are variable costs that change based on the quantity of a product or service. However indirect costs are fixed costs.
Direct Expenses are the expenses which are incurred in the manufacture of a product or provision of services. As against, Indirect Expenses are incurred in connection to the day to day business operations. Direct Expenses are outrightly allocable to the particular cost object or cost unit.
