High low method uses the lowest production quantity and the highest production quantity and comparing the total cost at each production level. It uses only the lowest and highest production activities to estimate the variable and fixed cost, by assuming the production quantity and cost increase in linear. It ignores the other points of productions, so it may be an error when the cost does not increase in a linear graph. The two points are not representing the production cost at a normal level.

J&L wants to predict their total costs if they complete 25 corporate tax returns in the month of February. 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. Similar to management accounting, cost accounting is the process of allocating costs to cost items, which often comprise a business’s products, services, and other activities. Cost accounting is useful because it can show where a company spends money, how much it earns, and where it loses money. Its drawback, however, is that not all data points are considered in the analysis.

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. If the business is established, this could be done by comparing the same time period in different years.
Functions of Cost Equations
It only requires the high and low points of the data and can be worked through with a simple calculator. The method does not represent all the data provided since it relies on just two extreme activity levels. Those activity levels may not be representative of the costs incurred, due to outlier costs that are higher or lower than what the organization incurs in other activity levels. Simply adding the fixed cost (Step 3) and variable cost (Step 4) gives us the total cost of factory overheads in April. To demonstrate how a company would use a scatter graph, let’s turn to the data for Regent Airlines, which operates a fleet of regional jets serving the northeast United States. The Federal Aviation Administration establishes guidelines for routine aircraft maintenance based upon the number of flight hours.
The Difference Between the High-Low Method and Regression Analysis
Let’s examine the cost data from Regent Airline using the https://www.simple-accounting.org/. 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. In the sample data above, the number of client calls refers to the activity level. The activity level can pertain to any measurable business activity, such as documents processed, units produced, finished goods inspected, or services rendered.
What is the High-Low Method in Accounting?
Let’s take an example to understand the calculation of the High Low Method in a better manner. For example, the table below depicts the activity for a cake bakery for each of the 12 months of a given year.
In scatter graphs, cost is considered the dependent variable because cost depends upon the level of activity. The activity is considered the independent variable since it is the cause of the variation in costs. Regent’s scatter graph shows a positive relationship between flight hours and maintenance costs because, as flight hours increase, maintenance costs also increase. This is referred to as a positive linear relationship or a linear cost behavior. When creating the scatter graph, each point will represent a pair of activity and cost values. Maintenance costs are plotted on the vertical axis (Y), while flight hours are plotted on the horizontal axis (X).
As a result, Regent finds that its maintenance costs vary from month to month with the number of flight hours, as depicted in Figure 2.29. Using this equation, the Beach Inn can now predict its total costs (Y) for the month of July, when they anticipate an occupancy of 93 nights. Now, the Beach Inn can apply the cost equation in order to forecast total costs for any number of nights, within the relevant range. High Low method will give us the estimation of fixed cost and variable cost, the result may be changed when the total unit and cost of both point change. By substituting the amounts in the cost equation of the lowest point, we can determine the fixed cost (a). The computations above show that the actual total costs and computed total costs using the equation don’t match.

The high-low method may produce inaccurate results since it only considers two extreme data points, which may not be representative of other data points. It can also be unreliable because it’s possible that the highest and lowest points are outliers. When you encounter an outlier, simply remove it from the dataset and use the high-low method for the remaining observations.
In this example the highest activity is 2,700 units and the lowest activity is 500 units. In March, Waymaker produced 1,000 units and used 2,000 hours of production labor. This method, also known as the “high low points,” calculates the semi-variable cost by examining the entire cost difference between two volumes and dividing the extra cost by the volume.

You can then use these estimates in preparing your budgets or analyzing an expected monetary value for a contingency reserve. The bsc applied accounting is used to calculate the variable and fixed cost of a product or entity with mixed costs. It considers the total dollars of the mixed costs at the highest volume of activity and the total dollars of the mixed costs at the lowest volume of activity. The total amount of fixed costs is assumed to be the same at both points of activity. The change in the total costs is thus the variable cost rate times the change in the number of units of activity. The high-low method in accounting is the simplest and easiest way to separate mixed costs into their fixed and variable components.
Some common examples of these costs are supervision costs and marketing costs. Costs are further differentiated into various sub-parts, each with its own significance in accounting and economics. Management accountants work for public companies, private companies, and government offices. Their roles are to collect, observe, and record numbers; advise on the company’s investments and manage them, and manage budgeting, planning, risk management, and decision-making.

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). Once we have arrived at variable costs, we can find the total variable cost for both activities and subtract that value from the corresponding total cost to find a fixed cost. 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 next point on the graph will represent 23,000 hours and $90,000 in costs, and so forth, until all of the pairs of data have been plotted.
- Rent, depreciation, interest on loans, and lease charges are all examples.
- The total amount of fixed costs is assumed to be the same at both points of activity.
- Suppose the variable cost per unit is fixed, and fixed costs at the highest and lowest production levels remain the same.
- A financial professional will offer guidance based on the information provided and offer a no-obligation call to better understand your situation.
It is presented in total, so we can’t immediately determine the fixed or variable components. Once variable cost per unit is found, you can calculate the fixed cost by subtracting the total variable cost at a specific activity level from the total cost at that activity level. The high low method has allowed a total cost to be split into variable and fixed cost components.
First, you must calculate the variable cost component and then the fixed cost component, and then plug the results into the cost model formula. The high low method can be relatively accurate if the highest and lowest activity levels are representative of the overall cost behavior of the company. However, if the two extreme activity levels are systematically different, then the high low method will produce inaccurate results.
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. Furthermore, unless you have access to a computer, computations necessitated by the least squares approach are tedious and time-consuming. Cost behavior describes how costs change as a result of changes in business activities. For example, a firm’s electricity cost will increase when working hours are increased. Management accounting refers to identifying, analyzing, and communicating financial information to a firm’s managers to achieve the company’s future goals. Fixed costs are expenses that remain the same irrespective of the quantity or number of units of goods produced for sale or services rendered.
