The long-run average cost (LRAC) curve shows the lowest cost for producing each quantity of output when fixed costs can vary, and so it is formed by the bottom edge of the family of SRAC curves. If a firm wished to produce quantity Q 3 , it would choose the fixed costs associated with SRAC 3 .

Long-run average total cost (LRATC) is a business metric that represents the average cost per unit of output over the long run, where all inputs are considered to be variable and the scale of production is changeable. The long-run average cost curve shows the lowest total cost to produce a given level of output in the long run. Long-term unit costs...
For instance, if a manufacturing company builds a new, larger plant for production, it is assumed that the LRATC per unit would eventually become lower than at the old plant as the company takes advantage of certain economies of scaleor the cost advantages that come from expanding the scale of production. When the scale of production is expanded, a...
The calculation of the LRATC may be represented as a curve showing the lowest costs that a company will be able to reach for any degree of output over time. The shape of that curve can closely resemble the curve calculated for short-run average total costs. The LRATC can be seen as made up of a series of short-run curves as a company improves its e...
For example, in the video game industry, the costs to produce a game are high. However, the cost of making copies of a game, once produced, is marginal. So, once a company can establish itself, expand the customer base for a specific game, and raise demand for that game, the extra output required to meet that demand lowers overall cost in the long ...

Long run Average Cost (LAC) is equal to long run total costs divided by the level of output. The derivation of long run average costs is done from the short run average cost curves. In the short run, plant is fixed and each short run curve corresponds to a particular plant.
Interpret graphs of long-run average cost curves and short-run average cost curves. Analyze cost and production in the long run and short run. The long run is the period of time when all costs are variable. The long run depends on the specifics of the firm in question—it is not a precise period of time.

Long run cost is the minimal cost of producing any given level of output when all individual factors are variable. The long run cost curve helps us understand the functional relationship between out and the long run cost of production. In this article, we will look at understanding the long run average cost curve.
