How to Calculate Long Run Average Total Cost (LRATC)
The Long Run Average Total Cost (LRATC) is a critical metric for assessing the efficiency of production over an extended period. Understanding LRATC allows companies to optimize production and achieve competitive advantages in their respective industries.
Understanding the LRATC Curve
LRATC is represented by a curve illustrating the lowest costs achievable by a company for varying levels of output over time. The shape of this curve is analogous to the Short-Run Average Total Cost curve but encompasses efficiencies gained through scaling production.
Components of the LRATC Calculation
Calculating LRATC involves understanding its three-phase curve: 1. Economies of scale—where costs decrease as output increases due to spreading out fixed costs.2. Constant returns to scale—where costs remain stable relative to output.3. Diseconomies of scale—where costs increase with further increases in output, usually due to inefficiencies as the company scales.
Evaluating Cost Efficiency
To determine LRATC practically, consider both the developmental and operational costs over time. A sound evaluation includes the cost of developing products and technologies against the efficiency improvements in production processes.
Practical Example
Consider the video game industry, where initial development costs are high but the marginal cost of producing additional units (copies of a game) is low. As production scales, the average total cost per unit diminishes, illustrating economies of scale and the significance of the LRATC curve in strategic planning.
By understanding the components and behavior of the LRATC curve, companies can make informed decisions about scaling production to achieve the lowest long-term costs.
How to Calculate Long Run Average Total Cost
The Long Run Average Total Cost (LRATC) is a vital metric for understanding the minimum cost per unit a company can achieve over time when all inputs are variable. To effectively calculate LRATC, you must consider the cost across different scales of production, ensuring that you identify the optimal cost for various output levels.
Understanding the LRATC Curve
The LRATC curve is depicted as having three key phases: economies of scale, constant returns to scale, and diseconomies of scale. Each phase relates to how cost behaviors change with varying output levels. In the economies of scale phase, increasing production leads to lower costs per unit; in the constant returns to scale phase, costs per unit stabilize; and under diseconomies of scale, costs per unit increase with further increases in output.
Steps to Calculate LRATC
To compute the LRATC, follow these steps:
- Identify the total costs associated with various production levels over the long run, where all inputs are adjustable and the scale of production can be changed.
- Calculate the total cost for each level of output.
- Divide the total cost by the corresponding output level to find the average total cost for each output level.
- Plot these average costs against their respective output levels to visualize the LRATC curve.
- Identify the lowest point on this curve for each output level, as this represents the lowest achievable cost per unit.
Through careful analysis and plotting of different production scales, businesses can utilize the LRATC curve not only to understand their cost structure but also to strategize about scaling production efficiently to minimize costs.
Practical Example
Consider the video game industry, where initial development costs are substantial, yet the cost to replicate software is relatively low. Here, expanding the number of game units produced significantly decreases the average cost per unit in the long run, illustrating the concept of economies of scale effectively captured in the LRATC curve.
By following these guidelines, businesses can optimize production to achieve minimal long-term costs, enhancing profitability and competitiveness in their respective markets.

Examples of Calculating Long Run Average Total Cost
Example 1: Manufacturing Industry
In the manufacturing sector, a company produces goods with variable input costs and capital costs. Consider a scenario where total cost (TC) over a given period includes $100,000 in fixed investments and $50,000 in variable costs that depend on output levels. To find the long run average total cost (LRATC), assume the output level is $5,000$ units. The LRATC is calculated by the formula LRATC = TC / Q, where Q is the quantity of output. Hence, LRATC = ($100,000 + $50,000) / 5,000 = $30 per unit.
Example 2: Technology Firm
Consider a tech firm that invests $200,000 in R&D and equipment, along with $300,000 in salaries for developers, irrespective of output levels. If the later technology sales result in the production of $10,000$ units, the LRATC can be derived as follows: LRATC = ($200,000 + $300,000) / 10,000 = $50 per unit. This calculation shows how spreading fixed costs over a larger output reduces the LRATC, emphasizing economies of scale.
Example 3: Retail Business
A retail chain may incur $150,000 in leasing and $100,000 in staffing annually, with expected sales of $20,000$ units of various products. Calculating the LRATC involves summing the total cost and dividing by total units sold: LRATC = ($150,000 + $100,000) / 20,000 = $12.50 per unit. This figure helps the business in pricing and budget strategies.
Example 4: Small Bakery
A small bakery's annual costs include $30,000 for kitchen equipment and $20,000 for ingredients and labor. If it produces $3,000$ loaves of bread annually, the LRATC calculation would be: LRATC = ($30,000 + $20,000) / 3,000 = $16.67 per loaf. This example illustrates how fixed and variable costs affect pricing in small-scale operations.
