Overview of High-Low Method
Definition of
High-Low Method
What is the High-Low Method? The High-Low Method is a straightforward technique used in cost accounting to estimate and separate the fixed and variable components of a mixed cost (a cost containing both elements). It works by analyzing historical data and selecting the periods with the highest and lowest levels of activity (e.g., units produced, machine hours) and their corresponding total costs within a relevant range. By comparing the change in cost between these two points relative to the change in activity, one can isolate the variable cost per unit and subsequently determine the total fixed cost. This method provides a simple formula for estimating future costs based on activity levels: Total Cost = Fixed Costs + (Variable Cost per Unit * Activity Level).
Activities Related to
High-Low Method
Here is a list of High-Low Method related activities:Â
Identifying periods of highest and lowest activity, Collecting total cost data for those periods, Calculating the variable cost per unit of activity, Determining the total fixed cost component, Developing a cost formula (Total Cost = Fixed Costs + (Variable Cost per Unit * Activity Level)), Estimating future costs based on projected activity levels, Performing basic Cost-Volume-Profit (CVP) analysis, and Assisting in budget planning and short-term decision making.
This method is often used in managerial accounting when a quick estimate of cost behavior is needed for internal analysis.
The Importance of
High-Low Method
For small business owners and managers, the High-Low Method offers a simple and quick way to understand how their costs behave in relation to business activity. Separating fixed costs (like rent) from variable costs (like direct materials) is crucial for effective budgeting, forecasting future expenses, setting prices, and making informed decisions about production levels or service offerings. While less precise than statistical methods like regression analysis, its ease of calculation makes it a valuable tool for preliminary cost analysis and understanding basic cost structures, especially when detailed data or resources for complex analysis are limited.
Key Aspects of
High-Low Method
Simplicity
Its primary advantage is its ease of understanding and calculation, requiring only two data points (highest and lowest activity levels and their associated total costs).
Cost Separation
Specifically designed to break down mixed costs into their estimated fixed and variable components using a clear formula, aiding in understanding cost behavior.
Reliance on Extreme Points
Its main limitation is that it only considers the highest and lowest activity points within a data set. These points might be outliers and not representative of typical cost behavior, potentially leading to less accurate cost estimations compared to methods using all available data points (like regression analysis).
Concepts Related to
High-Low Method
The High-Low Method is a technique within Cost Accounting focused on analyzing cost behavior by separating mixed costs into Fixed Costs and Variable Costs. It fundamentally assumes a linear relationship between cost and activity level within the relevant range being examined. The results derived from this method are often used as inputs for Cost-Volume-Profit (CVP) Analysis, financial Budgeting, and forecasting activities. It serves as a simpler, though potentially less accurate, alternative to statistical methods like regression analysis for cost estimation.
