The **High-Low Method** is a widely used technique that simplifies this calculation by using only the highest and lowest activity levels to determine both the variable cost per unit and the fixed cost component of total costs.\n\nThis article provides a comprehensive guide to understanding and calculating variable cost per unit using the high-low method, including practical examples, real-world applications, and detailed explanations.\n\n## What is the High-Low Method?\n\nThe high-low method is a statistical technique used in managerial accounting to separate mixed costs (costs that contain both fixed and variable components) into their fixed and variable elements. It is one of the simplest methods for cost estimation and is often used in practice due to its ease of application and minimal data requirements.\n\nThe method relies on identifying the highest and lowest activity levels (usually measured in units produced, machine hours, or labor hours) and their corresponding total costs over a specific period. By comparing these two extreme points, the variable cost per unit and fixed costs can be calculated.\n\n### Key Concepts\n\n* **Variable Costs:** Costs that change in direct proportion to changes in activity levels. Examples include direct materials, direct labor, and sales commissions.\n* **Fixed Costs:** Costs that remain constant regardless of changes in activity levels within a relevant range. Examples include rent, salaries, and insurance.\n* **Mixed Costs:** Costs that have both fixed and variable components. Utilities, maintenance, and supervision costs are common examples of mixed costs.\n\n## How to Calculate Variable Cost Per Unit Using High Low Method\n\nThe calculation of variable cost per unit using the high-low method involves a straightforward, four-step process. Here is the step-by-step derivation and explanation of the formula.\n\n### Step 1: Identify the Highest and Lowest Activity Levels\n\nFirst, gather data on the activity level (e.g., units produced, machine hours) and total costs for several periods. From this data, identify the period with the highest activity level and
