What is the High-Low Method in Accounting? Explained

To understand the high-low method, first, we need to understand management accounting. The high-low method is used in the field of management accounting, which is an essential part of accounting. Due to its unreliability, high low method should be carefully used, usually in cases where the data is simple and not too scattered. For complex scenarios, alternate methods should be considered such as scatter-graph method and least-squares regression method. 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.

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. Harold Averkamp (CPA, MBA) has worked as a university accounting instructor, accountant, and consultant for more than 25 years. High-low point method is simple and easy to use but has some serious limitations.

The end result may not be as accurate as with other approaches but will generally be more than sufficient for most purposes, especially for SMEs. The main benefit of the high-low method is that it is simple to implement. When reviewing your company’s production and cost data, you will first have to find the highest and lowest quantity of items produced.

• Cost behavior describes how costs change as a result of changes in business activities.
• So, the differential cost of USD 10,000 divided by differential units of 4,000 results in USD 2.5 per unit (10,000/4,000).
• For example, the rent you pay on the production facility will be the same whether you produce one cell phone case or one million cases.
• Although easy to understand, high low method may be unreliable because it ignores all the data except for the two extremes.

If the variable cost is a fixed charge per unit and fixed costs remain the same, it is possible to determine the fixed and variable costs by solving the system of equations. In cost accounting, the high-low method is a technique used to split mixed costs into fixed and variable costs. Although the high-low method is easy to apply, it is seldom used because it can distort costs, due to its reliance on two extreme values from a given data set. This cost includes a fixed charge and a variable element (fixed cost + variable element).

The Difference Between the High-Low Method and Regression Analysis

She has been assigned the task of budgeting payroll costs for the next quarter. Although this is a really easy and understandable method, there are a few shortcomings to this method that make it less practical. This method has disadvantages in that it fits a straight line to any set of cost data, regardless of how unpredictable the cost behavior pattern is.

It is important to note that if a higher level of activity is above a threshold of normal production. One has to consider step fixed cost/additional fixed cost to come up with the full fixed cost. So, to produce additional 5,000 units, the company has to extend their production facility, which is expected to incur the cost same as the previous facility of 10,000 units. Hence, once the limit of normal production capacity is reached, the company has to incur another fixed cost irrespective of additional units to be produced. Hence, the difference in total costs in both months is due to the difference in product level. Although easy to understand, high low method may be unreliable because it ignores all the data except for the two extremes.

Cost management allows us to forecast future expenses and plan accordingly. It also aids in the control of project costs and the pre-determination of maintenance costs. We can examine long-term company trends and achieve the business goals with proper cost management. 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.

The high-low method is a straightforward analysis that requires little calculation. It simply requires the data’s high and low points and maybe worked out using a simple calculator. However, because it only analyzes the extreme high and low numbers and removes the influence of any outliers, the formula does not take inflation into account and produces a very imprecise estimate. The division of differential cost with the differential level of activity results in the variable cost per unit. So, the differential cost of USD 10,000 divided by differential units of 4,000 results in USD 2.5 per unit (10,000/4,000). Similarly, the variable cost of producing 10,000 units has been deducted from the total cost of USD 55,000 at the higher level of activity.

Management accounting involves decision-making, planning, coordinating, controlling, communicating, and motivating. Similar to management accounting and financial accounting, there is cost accounting to determine the cost of a product. By contrast, the high-low method is simple enough to be used by anyone who understands basic maths. In fact, very small businesses (e.g. freelancers) could probably do the necessary calculations with just a basic calculator.

It makes use of certain techniques to deduct an element of fixed cost from the total cost. The method makes use of two different levels of activities and related costs. In order to successfully understand and use this technique we first need to be clear about how costs are categorised and this is based on how they behave. A cost that contains both fixed and variable costs is considered a mixed cost.

The fixed costs are considered to be the same for both levels of activity. Variation in the total costs is the variable cost rate about the variation in the number of units produced or manufactured. The high-low method is used to calculate the variable and fixed cost of a product or entity with mixed costs.

It is used to estimate the projected total cost at any given level of activity under the assumption that past performance may be practically extrapolated to future project costs. The method’s core principle is that the change in total costs is equal to the variable cost rate multiplied by the change in the number of units of activity. In the previous article we looked at call charges and we knew the cost for 30 incredible employee retention statistics 100 minutes was £34 but that for 180 minutes it increased to £58. As the total costs were different at the two levels of output we already knew this wasn’t as fixed cost. It turned out that the variable costs per unit were different too, so it wasn’t that either. Consequently, we deduced that the cost of the calls must be a combination of a fixed element and a variable element which made it semi-variable.

Relevant/ Irrelevant costs – These are also known as avoidable and unavoidable costs. Avoidable costs are the ones that are affected by the decision of a manager, whereas unavoidable costs are costs that are not affected by the decision of managers. Some common examples of these costs are supervision costs and marketing costs. It is commonly practiced to assist managers in making crucial business decisions, as it provides them with actual statistics and critical data that help with decisions.

Cost accounting is a type of managerial accounting that attempts to capture a company’s entire cost of production by analyzing both variable and fixed costs, such as a leasing fee. Hence, the numerator is left with the variable cost of the differential units, and when the variable cost of differential units is divided with differential units it results in variable cost per unit. Let’s understand this procedural format of the concept with the following example. There are also other cost estimation tools that can provide more accurate results. The least-squares regression method takes into consideration all data points and creates an optimized cost estimate. It can be easily and quickly used to yield significantly better estimates than the high-low method.

The variable cost per unit is then computed by dividing the expression from step 3 by the expression from step 4, as shown above. After a certain level of production, a firm requires more fixed investments, which cannot be covered by this method; therefore, this method should be used with extreme caution. This method looks at the entire cost difference between two volumes and divides the extra cost by the volume. Cost behavior describes how costs change as a result of changes in business activities. For example, the electricity cost for a firm will increase when working hours are increased.

Variable cost per unit refers to the cost of producing each unit, which varies as output volume or activity level increases. These are not committed costs because they arise only if the company is producing. The Total cost refers to a summation of the fixed and variable costs of production. Suppose the variable cost per unit is fixed, and fixed costs at the highest and lowest production levels remain the same. In that case, the high-low method calculator applies the high-low method formula to evaluate the total costs at any given amount of production. You can then use these estimates in preparing your budgets or analyzing an expected monetary value for a contingency reserve.
