Some costs may rise gradually, while others may jump at certain activity levels. If a business experiences sudden price hikes or seasonal variations, the high-low method may give misleading results. Fixed costs can be found be deducting the total variable cost for a given activity level (i.e. 6000 or 4000) from the total cost of that activity level. 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 basis for choosing the highest or lowest cost should be based on the level of activity. The lowest activity level should determine the lowest cost ditto for the highest cost.

Understanding the High Low Method: A Complete Guide
(-) One of the High/Low points, or both, might not be representative of the costs usually incurred at those unit volume levels. We can mitigate this risk by calculating the model with more data points to confirm the relationship between the costs. This may lead us to conclude that a point is an outlier, and we can then exclude it from our analysis, to get a more reliable cost model. Additionally, it provides a way for analysts to make an approximate estimation of future unit costs. However, this method does not account for inflation and is not very precise because it only takes into account the extreme values and disregards any outliers. The high-low method is not very reliable because it only considers two extreme levels of activity.
What are the main limitations of the high-low method?
- However, it is essential to remember that the method is an estimate, and we should only use it in corroboration with other sources of information where possible.
- However, this method does not account for inflation and is not very precise because it only takes into account the extreme values and disregards any outliers.
- While this approach is time-consuming, it provides the most detailed breakdown of expenses.
- 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.
When used alongside other cost estimation methods, it can serve as a starting point for financial planning. Fixed costs—like rent, insurance, and salaries—stay the same no matter how much you produce. Variable costs—like raw materials, shipping fees, or sales commissions—rise and fall with business activity.
Advantages and Limitations of the High-Low Method
The high-low method uses only the highest and lowest activity levels to estimate fixed and variable costs, making it quick but less precise. Regression analysis, on the other hand, considers all data points to provide a more accurate cost estimation by identifying the relationship between variables. While regression analysis offers greater accuracy, it requires more complex calculations and data. The high-low method is a simple, fast way to estimate costs when only basic financial data is available. By identifying the highest and lowest activity levels, businesses can separate fixed and variable costs to better understand their expense structure.
It is important to remember here that it is the highest and lowest activity levels that need to be identified first rather than the highest/lowest cost. (-) The High-Low method does not consider costs that don’t change proportionally with unit volume changes, but rather at discrete points, also known as Step Costs. Using the change in cost, the high low method accounting formula allows the variable cost per unit to be calculated. Despite its limitations, the high-low method is good for making quick decisions. If a business needs a rough estimate for an upcoming expense, this method provides a fast solution without requiring detailed analysis.
In an examination question, instances, where the high low method may appear to be technical, is when inflation is factored to be in the costs.

To enhance accuracy, it’s advisable to use the high-low method as a preliminary tool and follow up with more detailed analyses like regression analysis. Ensuring that the highest and lowest activity levels used are typical and not anomalies can also improve the reliability of the estimates. While the high-low method is easy to use, it comes with some serious drawbacks. Since it only considers the highest and lowest activity levels, it doesn’t account for changes in cost behavior that may occur between these two points.
He has been a manager and an auditor with Deloitte, a big 4 accountancy firm, and holds a degree from Loughborough University. As an example of how to calculate high low method, suppose a business what is overhead cost and how to calculate it had the following information relating to its costs. Highest activity level is 21,000 hours in Q4.Lowest activity level is 15,000 hours in Q1.
However, the accuracy of the regression analysis is heavily dependent on the quality of the data set used. The final step in the high low method is to calculate the fixed cost component. However, businesses with seasonal variations or highly irregular expenses should be cautious when using this method.
- 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.
- However, the accuracy of the regression analysis is heavily dependent on the quality of the data set used.
- And it may not accurately represent the typical costs incurred at those levels due to abnormal costs that are either higher or lower than usual.
- It assumes that costs change at a constant rate, which may not always be true.
High Low Method in Accounting
The fixed cost can be calculated once the variable cost per unit is determined. High low method is the mathematical method that cost accountant uses to separate fixed and variable cost from mixed cost. We use the high low method when the cost cannot clearly separate due to its nature.
Understanding the concept of the high-low method is imperative because it is usually used in preparing the corporate budget. It is used in estimating the expected total cost at any given level of activity based on the assumption that past performance can be practically applied to project cost in the future. The underlying concept of the method is that the change in the total costs is the variable cost rate multiplied by the change in the number of units of activity.

Given the dataset below, develop a cost model and predict the costs that will be incurred in September. Let us try to understand the concept of high-low method total cost formula with the help of some suitable examples. Let us look at an example to understand better how to apply the High-Low method. We start with our reference data, which will be used to forecast costs for FY 2019. Therefore we have the Costs and the Units Volume of production for FY 2018 as a starting point.
In cost accounting, the high-low method is fundamental for analyzing the cost model of production. It aids in understanding how costs behave with changes in the levels of production, providing critical insights for decision-making processes. It enables businesses to predict the cost of production for different levels of activity, enhancing budgeting and cost control. The high low method is applied when there is the need to split total costs into its fixed and variable components.
However, it is essential to remember that the method is an estimate, and we should only use it in corroboration with other sources of information where possible. Noticing such deviation is a reliable indicator that we should exclude the data point from our analysis. This means that for every additional mile driven, fuel costs increase by $1.20. 23,000 hours are expected to be worked in the first quarter of the next year. The following are the given data for the calculation of the high-low method.
