The cost accounting technique of the high-low method is used to split the variable and current portion of long term debt fixed costs. The mathematical expression for the high-low method takes the highest and lowest activity levels from an accounting period. The activity levels are then apportioned against the highest and lowest number of units produced. The one element of the total cost then provides the second element by deducting it from the total costs.
For complex scenarios, alternate methods should be considered such as scatter-graph method and least-squares regression method.

Now add the fixed cost (step 3) and variable cost for the new activity (step 4) together to get the total cost of overheads for May. We can calculate the variable cost and fixed cost components by using the High-Low method. 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. Regression analysis helps forecast costs as well, by comparing the influence of one predictive variable upon another value or criteria.

We and our partners process data to provide:
- Simply adding the fixed cost (Step 3) and variable cost (Step 4) gives us the total cost of factory overheads in April.
- Further, the process may be easy to understand, but the high-low method is not considered reliable because it ignores all the data except the two extreme ones.
- Therefore, the overhead cost is expected to be $65,000 for March 2019.
- Such a cost function may be used in budgeting to estimate the total cost at any given level of activity, assuming that past performance can reasonably be projected into future.
- Regression analysis is also best performed using a spreadsheet program or statistics program.
It assumes that fixed and unit variable costs are constant, which is not always the case in real life. Once you have the variable cost per unit, you can calculate the fixed cost. 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. From all the above examples, we get a lot of clarity regarding the concept and how to calculate the same from data that we get in the financial statements.
What Is the High-Low Method in Accounting?
Bonnie runs a small car factory in Detroit and needs to know the expected amount of overheads the factory will incur in the next month. There are a number of accounting techniques used throughout the business world. However, the formula does not take inflation into consideration and provides a very rough estimation because it only considers the extreme high and low values, and excludes the influence of any outliers. In other words, it does not account for any influence of outliers which are the data that vary to a significant extent from the normal set of data.
Nevertheless, it has limitations, such as the high-low method assumes a linear relationship between cost and activity, which may be an oversimplification of cost behavior. Further, the process may be easy to understand, but the high-low method is not considered reliable because it ignores all the data except the two extreme ones. Let us try to understand the concept of high-low method total cost formula with the help of some suitable examples.
Step 1: Find Out the Highest and Lowest Activity Level
The high-low method is used to calculate the variable and fixed costs 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.
She has been assigned the task of budgeting payroll costs for the next quarter. The high-low method only requires the high and low points of the data and can be worked through with a calculator. 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.
It also does not account for inflation, thus providing a very rough estimation. The calculation follows simple process and step, which is better than the other complex methods like least-square regression. It is a very simple and easy way to divide the costs of the entity in a methodical manner, even if the information available is very less. Therefore, the overhead cost is expected to be $65,000 for March 2019. Whether it’s to figure out the profitability of a product, or getting an overview of the overall financial health of your business.
Step 5: Calculate the Total 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. 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. The cost amounts adjacent to these activity levels will be used in the high-low method, even though these cost amounts are not necessarily the highest and lowest costs for the year. Although easy to understand, high low method may be unreliable because it the direct write off method and its example ignores all the data except for the two extremes. It can be argued that activity-cost pairs (i.e. activity level and the corresponding total cost) which are not representative of the set of data should be excluded before using high-low method.
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. 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. Thus, it calculates the variable costs where the linear correlation holds true.
