What Is the High-Low Method in Accounting?
Unfortunately, the only available data is the level of activity (number of guests) in a given month and the total costs incurred in each month. 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 used to separate out fixed and variable costs in a limited set of data. We can calculate the variable cost and fixed cost components by using the High-Low method. The process of calculating the estimated fixed costs and variable costs takes a step by step approach with the High-Low method. As compared to scatter graph and least squares regression method, working with high-low point method is simple and easy.
Step 03: Find the fixed cost element
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. From all the above examples, we get a lot of clarity regarding the concept and how to calculate the same from data that we get in the financial statements. It is possible for the analysts and accountants to use this method effectively for determining both the fixed and variable cost component. Due to the simplicity of using general and administrative expense the high-low method to gain insight into the cost-activity relationship, it does not consider small details such as variation in costs.
The biggest advantage of the High-Low method is that uses a simple mathematical equation to find out the variable cost per unit. Once a company calculates the variable cost, it can then assign the fixed cost for any activity level during that period. As the company can use it to predict the portion of fixed costs with fluctuating activity levels.
Step 01: Determine the highest and lowest level of activities and unit produced
In order to help you advance your career, CFI has compiled many resources to assist you along the path. How often this needs to happen depends on how often and how significantly prices change. Given that all prices tend to increase over time (inflation), businesses should probably look to undertake high-low modelling at least once a year. In sectors where prices change rapidly, businesses may need to undertake high-low modelling more frequently. The results of high-low modelling are only valid for as long as the data underpinning them is valid. This means that businesses will need to repeat the high-low modelling exercise periodically to refresh the figures.
Ethical and Informed Consent for Data Used
Assume that the cost of electricity at a small manufacturing facility is a mixed cost since the company has only one electricity meter for air quality, cooling, lighting, and for its production equipment. The company wants to know the rate at which its electricity cost changes when the number of machine hours change. The part of the electric bill that does not change with the number of machine hours is known as the fixed cost. Continuing with this example, if the total electricity cost was $18,000 when there were 120,000 MHs, the variable portion is assumed to have been $12,000 (120,000 MHs times $0.10).
Data Availability and Access
- For complex scenarios, alternate methods should be considered such as scatter-graph method and least-squares regression method.
- In most real-world cases, it should be possible to obtain more information so the variable and fixed costs can be determined directly.
- The method is a simple mathematical equation that splits the semi-variable costs into variable and fixed costs.
- The fixed cost can then be calculated at the specific activity level i.e. either high level or low level of activity.
- We can calculate the variable cost and fixed cost components by using the High-Low method.
- High Low Method is a mathematical technique used to determine the fixed and variable elements of a historical cost that is partially fixed and partially variable.
- For example, the table below depicts the activity for a cake bakery for each of the 12 months of a given year.
The calculation follows simple process and step, which is better than the other complex methods like least-square regression. Below is a break down of subject weightings in the FMVA® financial analyst program. As you can see there is a heavy focus on financial modeling, finance, Excel, business valuation, budgeting/forecasting, PowerPoint presentations, accounting and business strategy. How much this matters depends on the extent of the variation between the pricing levels. If it’s fairly low, then it might be pragmatic just to accept it as the impact should be minor.
Given the dataset below, develop a cost model and predict the costs that will be incurred in September. If service contracts use variable pricing, there is a strong possibility that this pricing is tiered. There is also a strong possibility that the rate of increase is non-linear. This can effectively make it impossible to get a true average variable cost. This can be used to calculate the total cost of various units for the bakery.
The issue of outlier data
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.
However, this method has some serious limitations which the managers must be fully aware of before using it to separate variable and fixed portions of a mixed cost. The high or low points used for the calculation may not represent the costs normally incurred at those volume levels due to outlier costs that are higher or lower than would normally be incurred. Although the high-low method is designed to be used to calculate costs at maximum and minimum output, the formula can be used for any level of output. It can be useful to apply the formula to different levels of production if any of your variable costs increase in a non-linear way.
- It is a very simple and easy way to divide the costs of the entity in a methodical manner, even if the information available is very less.
- This network enhances the attention paid to pertinent knowledge points across both global and local scales, thereby adeptly capturing the underlying connections between global and local interaction sequences.
- For example, the least-squares regression is a method that takes into consideration all data points and creates an optimized cost estimate.
- Further, the process may be easy to understand, but the high-low method is not considered reliable because it ignores all the data except the two extreme ones.
- In sectors where prices change rapidly, businesses may need to undertake high-low modelling more frequently.
- 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.
It is a nominal difference, and choosing either fixed cost for our cost model will suffice. quickbooks undeposited funds account explained Whether you use the high point or the low point, the fixed costs calculated should be the same(1). The high-low method does not consider small details such as variation in costs. It assumes that fixed and unit variable costs are constant, which is not always the case in real life. The next step is to calculate the variable cost element using the following formula. It only requires the high and low points of the data and can be worked through with a simple calculator.
The high-low method is generally not preferred, as it can yield an incorrect understanding of the data if there are changes in variable- or fixed-cost rates over time or if a tiered pricing system is employed. In most real-world cases, it should be possible to obtain more information so the variable and fixed costs can be determined directly. Thus, the high-low method should only be used when it is not possible to obtain actual billing data. The highest activity for the bakery occurred in October, when it baked the highest number of cakes, while August had the lowest activity level, with only 70 cakes baked at a cost of $3,750.
Since the total electricity cost was $18,000 and the variable cost was calculated to be $12,000, the fixed cost of electricity for the month must have been the $6,000. If we use the lowest level of activity, the total cost of $16,000 would include $10,000 of variable cost (100,000 MHs times $0.10) with the remainder of $6,000 being the fixed cost for managing sales tax the month. The fixed cost is determined by calculating the variable costs using the rate calculated above and the number of units, and deducting this from the total cost. This calculation can be done using either the high or low values, but both are shown below for comparison. Thus, it calculates the variable costs where the linear correlation holds true. Like any other theoretical method, the High-Low method of cost allocation also offers some limitations.
High Low Variable Cost Formula
The high-low method assumes that fixed and unit variable costs are constant, which is not the case in real life. Because it uses only two data values in its calculation, variations in costs are not captured in the estimate. The high low method accounting formula states that the variable cost per unit is equal to the change in cost between the high and low cost values divided by the change in units between the same values.
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.

Calculate the expected factory overhead cost in April using the High-Low method. Let us try to understand the concept of high-low method total cost formula with the help of some suitable examples. Another drawback of the high-low method is the ready availability of better cost estimation tools. For example, the least-squares regression is a method that takes into consideration all data points and creates an optimized cost estimate. One potential issue with the basic approach to the high-low model is that it is vulnerable to outlier data. This can be addressed by hygiene-checking the data before it’s used for the calculation.
