The high-low point formula may, therefore, misrepresent the firm’s true cost behavior when it operates at normal activity level. When using this approach, Eagle Electronics must be certain that it is only predicting costs for its relevant range. For example, if they must hire a second supervisor in order to produce 12,000 units, they must go back and adjust the total fixed costs used in the equation.
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. The high-low point method uses only two data points (i.e., the wave accounting purchase order highest and the lowest activity levels) which are generally not enough to get the satisfactory results. Moreover, these highest and lowest points often do not represent the usual activity levels of a business entity.
- This is a very important concept in cost accounting and is very useful in determining fixed and variable costs related to the product, machinery, etc., and is also used in budgeting activities.
- Given the dataset below, develop a cost model and predict the costs that will be incurred in September.
- Thus, the high-low method should only be used when it is not possible to obtain actual billing data.
- Since you have the total cost equation now, you can use this to calculate your cost any month.
Once the variable cost per unit and the fixed costs are calculated, the future expected activity level costs can be determined using the same equation. The high-low method separates fixed and variable costs from the total cost by analyzing the costs at the highest and lowest levels of activity. It compares the highest level of activity and the lowest level of training and then compares costs at each level. 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.
Because it uses only two data values in its calculation, variations in costs are not captured in the estimate. Sometimes it is necessary to determine the fixed and variable components of a mixed cost figure. Several techniques are used for this purpose such as scatter graph method, least squares regression method and high-low point method.
As compared to scatter graph and least squares regression method, working with high-low point method is simple and easy. 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. Waymaker Furniture has collected cost information from its production process and now wants to predict costs for various levels of activity. 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.
This is the case for the managers at the Beach Inn, a small hotel on the coast of South Carolina. They know what their costs were for June, but now they want to predict their costs for July. We can calculate the variable cost and fixed cost components by using the High-Low method. However, in many cases, the increased production levels need additional fixed costs such as the additional purchase of machinery or other assets. 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.
Scenario Showing the Weakness of the High-low Method
It can also be unreliable because it’s possible that the highest and lowest points are outliers. The high low method excludes the effects of inflation when estimating costs. 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. The accountant at an events management company is preparing a payroll budget based on costs from the past year. A company needs to know the expected amount of factory overheads cost it will incur in the following month. To make the procedure simple and easy to understand, we can divide the calculations into the following three steps.
Is the high low method the only method for estimating fixed and variable costs?
Given the dataset below, develop a cost model and predict the costs that will be incurred in September. Let’s take a more in-depth look at the cost equation by examining the costs incurred https://www.wave-accounting.net/ by Eagle Electronics in the manufacture of home security systems, as shown in Table 2.9. The next step is to calculate the variable cost element using the following formula.

Now that we have this figure, let’s proceed to Step 3 to determine the total fixed cost. Sometimes, outliers—which are activity levels or costs that are abnormally high or low if compared to the rest of the observations—may exist in the data set. For instance, if the number of client calls in December reaches 1,000 calls, such is considered an outlier since it’s too far from the other observations. The high-low method is a simple analysis that takes less calculation work. It only requires the high and low points of the data and can be worked through with a simple calculator. In any business, three types of costs exist Fixed Cost, Variable Cost, and Mixed Cost (a combination of fixed and variable costs).
The high low method determines the fixed and variable components of a cost. It can be applied in discerning the fixed and variable elements of the cost of a product, machine, store, geographic sales region, product line, etc. No, there are other methods apart from the high-low method accounting formula. Some popular methods are the scatter plot method, accounting, and regression analysis. High Low Method provides an easy way to split fixed and variable components of combined costs using the following formula.
If the scatter graph reveals a linear cost behavior, then managers can proceed with a more sophisticated analyses to separate mixed costs into their fixed and variable components. However, if this linear relationship is not present, then other methods of analysis are not appropriate. Let’s examine the cost data from Regent Airline using the high-low method. The method is a simple mathematical equation that splits the semi-variable costs into variable and fixed costs. The analysis can also provide useful forecasts for future activity level cost analysis.
We and our partners process data to provide:
But more importantly, this scenario shows the weakness of the high-low method. Since our first computation excludes June, July, and August, we could not include its data in our cost equation. This only means that if we use the cost equation to project next year’s cost for June to August, then we may be underestimating costs in the budget.
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.
So the highest activity happened in the month of April, and the lowest was in the month of October. The high-low method involves three main steps to calculate the cost for any level of production. Variable costs are expenses that change depending on the quantity of production or number of units sold. You can us our labor cost calculator and VAT calculator to understand more on this topic. Fixed costs are expenses that remain the same irrespective of the quantity or number of units of goods produced for sale or services rendered. Highest activity level is 21,000 hours in Q4.Lowest activity level is 15,000 hours in Q1.
