# High-Low Method Definition, Formulas & Example

It uses this comparison to estimate the fixed cost, variable cost, and a cost function for finding the total cost of different production units. The manager of a hotel would like to develop a cost model to predict the future costs of running the hotel. 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).

This makes sense as snow removal costs are linked to the amount of snow and the number of flights taking off and landing but not to how many hours the planes fly. 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. 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. J&L can now use this predicted total cost figure of \$11,750 to make decisions regarding how much to charge clients or how much cash they need to cover expenses.

The highest activity level is 18,000 in Q4, and the lowest activity level is 10,000 in Q1. Regression analysis helps forecast costs as well, by comparing the influence of one predictive variable upon another value or criteria. However, regression analysis is only as good as the set of data points used, and the results suffer when the data set is incomplete. Using either the high or low activity cost should yield approximately the same fixed cost value. Note that our fixed cost differs by \$6.35 depending on whether we use the high or low activity cost. It is a nominal difference, and choosing either fixed cost for our cost model will suffice.

1. The biggest advantage of the High-Low method is that uses a simple mathematical equation to find out the variable cost per unit.
2. Once a company calculates the variable cost, it can then assign the fixed cost for any activity level during that period.
3. The high-low method calculator will help you find the variable cost per unit, fixed cost, and cost-volume model for your business operation with ease.
4. 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.

Using the maintenance cost data from Regent Airlines shown in Figure 2.32, we will examine how this method works in practice. If you’re interested in finding out more about fixed overhead volume variance, then get in touch with the financial experts at GoCardless. Find out how GoCardless can help you with ad hoc payments or recurring payments. Due to its unreliability, high low method should be carefully used, usually in cases where the data is simple and not too scattered.

Given the dataset below, develop a cost model and predict the costs that will be incurred in September. So the highest activity happened in the month of Jun, and the lowest was in the month of March. So the highest activity happened in the month of April, and the lowest was in the month of October. In March, Waymaker produced 1,000 units and used 2,000 hours of production labor. Highest activity level is 21,000 hours in Q4.Lowest activity level is 15,000 hours in Q1.

## Demonstration of the High-Low Method to Calculate Future Costs at Varying Activity Levels

Maintenance costs are plotted on the vertical axis (Y), while flight hours are plotted on the horizontal axis (X). For instance, one point will represent 21,000 hours and \$84,000 in costs. 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. Finally, a trend line is added to the chart in order to assist managers in seeing if there is a positive, negative, or zero relationship between the activity level and cost. In all three examples, managers used cost data they have collected to forecast future costs at various activity levels.

## The Difference Between the High-Low Method and Regression Analysis

If you can pay attention to its guidelines, it can easily organize your training, allow more time for sport, and give you your best results. When too many competing demands are placed on the body, the training methods often cancel each other out. The trick it to promote the most adaptation possible by aligning exercises and drills and applying the right doses at the right times. This requires a training structure to organize your work and optimize the benefits from your expenditure of time. The high low method excludes the effects of inflation when estimating costs. This book may not be used in the training of large language models or otherwise be ingested into large language models or generative AI offerings without OpenStax’s permission.

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 https://intuit-payroll.org/ should only be used when it is not possible to obtain actual billing data. Calculating the outcome for the high-low method requires a few formula steps. First, you must calculate the variable cost component and then the fixed cost component, and then plug the results into the cost model formula. 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.

## Construct total cost equation based on high-low calculations above

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. A scatter graph shows plots of points that represent actual costs incurred for various levels of activity.

The first step in analyzing mixed costs with the high-low method is to identify the periods with the highest and lowest levels of activity. We always choose the highest and lowest activity and the costs that correspond with those levels of activity, even if they are not the highest and lowest costs. Using this information and the cost equation, predict Waymaker’s total costs for the levels of production in Table 2.12. Multiply the variable cost per unit (step 2) by the number of units expected to be produced in May to work out the total variable cost for the month.

## The Nature of a Mixed Cost

Once the scatter graph is constructed, we draw a line (often referred to as a trend line) that appears to best fit the pattern of dots. When interpreting a scatter graph, it is important to remember that different people would likely draw different lines, which would lead to different estimations of fixed and variable costs. No merchant center intuit one person’s line and cost estimates would necessarily be right or wrong compared to another; they would just be different. 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.

The high-low method can be used to identify these patterns and can split the portions of variable and fixed costs. Simply multiplying the variable cost per unit (Step 2) by the number of units expected to be produced in April gives us the total variable cost for that month. 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.

It can be easily and quickly used to yield significantly better estimates than the high-low method. The accountant at an events management company is preparing a payroll budget based on costs from the past year. The high-low method involves three main steps to calculate the cost for any level of production. 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. An easy split is to use Monday, Wednesday, Friday for high intensity, and Tuesday and Thursday for low intensity.
