High-Low Method Definition, Formula, Calculate

June 22, 2021

The high-low method is used in the field of management accounting, which is an essential part of accounting. Using the maintenance cost data from Regent Airlines shown in Figure 2.32, we will examine how this method works in practice. He has a CPA license in the Philippines and a BS in Accountancy graduate at Silliman University.

  1. Variable cost per unit is constant within this activity range and there is a step up of 10% in the total fixed costs when the activity level exceeds 5,500 units.
  2. A cost is an expense needed to sell, create or acquire assets for a product or service.
  3. Choosing between high-low or regression analysis methods is only a matter of capability and expertise.
  4. The fixed cost can then be calculated at the specific activity level i.e. either high level or low level of activity.

An example of a relevant cost is future cost and opportunity cost, whereas irrelevant cost is sunk cost and committed cost. Some common examples of these costs are supervision costs and marketing costs. A cost is an expense needed to sell, create or acquire assets for a product or service. In other words, it is the monetary value of expenditure for supplies, services, etc.

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 https://www.wave-accounting.net/ fixed costs with fluctuating activity levels. Using a scatter graph to determine if this linear relationship exists is an essential first step in cost behavior analysis.

Using this information and the cost equation, predict Waymaker’s total costs for the levels of production in Table 2.12. Yes, because it is a simple tool to compute network mapping software costs at different activity levels. It can also be used for budgeting purposes, especially for business activities with fixed and variable components.

The higher production volumes also reduce the variable proportion of costs too. The high-low method can be used to identify these patterns and can split the portions of variable and fixed costs. The average activity level and the average cost for the periods in the database are then computed. The fixed cost is calculated by subtracting the variable cost for the average activity level from the total average cost. In all three examples, managers used cost data they have collected to forecast future costs at various activity levels. 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).

Example 2: High-Low Method with Inflation

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. Fixed costs are monthly expenses that do not change depending on the level of production. Rent, depreciation, interest on loans, and lease charges are all examples. 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.

Estimation is also useful for using current data to predict the effects of future changes in production on total costs. Three estimation techniques that can be used include the scatter graph, the high-low method, and regression analysis. Here we will demonstrate the scatter graph and the high-low methods (you will learn the regression analysis technique in advanced managerial accounting courses.

Variable Cost per Unit

In March, Waymaker produced 1,000 units and used 2,000 hours of production labor. Let’s take a more in-depth look at the cost equation by examining the costs incurred by Eagle Electronics in the manufacture of home security systems, as shown in Table 2.9. If the data is inaccurate, either method will produce inaccurate results. Good bookkeeping is still essential to ensure high-quality data for 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.

A company needs to know the expected amount of factory overheads cost it will incur in the following month. The company approves a 5% pay raise at the start of each year and expects that work hours will be 20,000 for the next quarter considering the new hires. It’s also possible to draw incorrect conclusions by assuming that just because two sets of data correlate with each other, one must cause changes in the other.

Separating variable and fixed costs can help you understand the business’ cost structure. Both of these costs have an impact on overall profitability and knowing each will help you make better decisions. Therefore, total fixed costs for client support calls is $1,500 per month. In the side-by-side computation above, we’ve proven our point that regardless of which reference point we use, we still arrive at $1,500. Difference between highest and lowest activity units and their corresponding costs are used to calculate the variable cost per unit using the formula given above. 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.

What Is the High-Low Method?

You will learn more about these various labels and how they are applied in decision-making processes as you continue your study of managerial accounting in this course. 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. Variable costs are expenses that change depending on the quantity of production or number of units sold.

Step 1: Determine the Highest and Lowest Activity Levels

Highest activity level is 21,000 hours in Q4.Lowest activity level is 15,000 hours in Q1. This can be used to calculate the total cost of various units for the bakery. 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. It can be easily and quickly used to yield significantly better estimates than the high-low method.

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. Understanding the various labels used for costs is the first step toward using costs to evaluate business decisions.

Now that we have this figure, let’s proceed to Step 3 to determine the total fixed cost. 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.
