Sometimes it is necessary to determine the fixed and variable components of a mixed cost figure. Several techniques are used for this purpose such as scatter graph method, least squares regression method and high-low point method. The variable cost per unit is equal to the slope of the cost volume line (i.e. change in total cost ÷ change in number of units produced). The high-low method is a simple way in cost accounting to segregate costs with minimal information.
The highest and lowest activity levels are September at 300 client calls and October at 100 client calls. As far as the high-low method is concerned, these are the only data points that we’ll use in the calculation. The high-low method used in analysis of costs that help in estimating the variable and fixed costs from a given data set of financial information.
This technique provides a simple and straightforward way to split fixed and variable components of combined costs. When analyzing costs as to behavior, costs are classified into fixed and variable costs. Before costs can be effectively used in analysis, they should be segregated into purely fixed and purely variable costs. High-low point method is a technique used to divide a mixed cost into its variable and fixed components. Such a cost function may be used in budgeting to estimate the total cost at any given level of activity, assuming that past performance can reasonably be projected into future. While the high-low method is an easy one to use, it also has its disadvantages.
Being a new hire at the company, the manager assigns you the task of anticipating the costs that would be incurred in the following month (September). The high-low method is an accounting technique that is used to separate out your fixed and variable costs within a limited set of data. Yes, because it is a simple tool to compute costs at different activity levels. It can also be used for budgeting purposes, especially for business activities with fixed and variable components. Separating variable and fixed costs can help you understand the business’ cost structure.

- Also, the high-low method does not use or require any complex tools or programs.
- When analyzing costs as to behavior, costs are classified into fixed and variable costs.
- As far as the high-low method is concerned, these are the only data points that we’ll use in the calculation.
- It is possible for the analysts and accountants to use this method effectively for determining both the fixed and variable cost component.
Also, the high-low method does not use or require any complex tools or programs. As compared to scatter graph and least squares regression method, working with high-low point method is simple and easy. However, this method has some serious limitations which the managers must be fully aware of before why does accumulated depreciation have a credit balance on the balance sheet using it to separate variable and fixed portions of a mixed cost. Although easy to understand, high low method may be unreliable because it ignores all the data except for the two extremes. It can be argued that activity-cost pairs (i.e. activity level and the corresponding total cost) which are not representative of the set of data should be excluded before using high-low method. You can now use this cost equation to project future costs of client support calls for budgeting purposes.

Good bookkeeping is still essential to ensure high-quality data for types of errors in accounting analysis. To learn more about bookkeeping, our guide on small business bookkeeping will teach you how to perform small business bookkeeping and how to organize accounting data appropriately. Nevertheless, it has limitations, such as the high-low method assumes a linear relationship between cost and activity, which may be an oversimplification of cost behavior.
Understanding the High-Low Method
The high-low method involves comparing total costs at the highest level of activity and the lowest level of activity, after each level is determined. The formula for high low method is quite simple and easy to understand. They are suitable for more complex cost structures and larger databases. Due to the simplicity of using the high-low method to gain insight into the cost-activity relationship, it does not consider small details such as variation in costs. The high-low method assumes that fixed and unit variable costs are constant, which is not the case in real life.
However, the formula does not take inflation into consideration and provides a very rough estimation because it only considers the extreme high and low values, and excludes the influence of any outliers. For example, the table below depicts the activity for a cake bakery for each of the 12 months of a given year. In other words, it does not account for any influence of outliers which are the data that vary to a significant extent from the normal set of data. It also does not account for inflation, thus providing a very rough estimation. The following are the given data for the calculation of the high-low method.
