High-Low Method: Learn How to Estimate Fixed & Variable Costs

The high-low method is a straightforward, if not slightly lengthy, way to figure out your total costs. Fixed costs are expenses that remain the same irrespective of the quantity or number of units of goods produced for sale or services rendered. The high-low method can be done graphically by plotting and connecting the lowest point of activity and the highest point of activity.

Advantages and disadvantages of the high-low method accounting formula

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. For the months from June to August, the actual costs are always higher than the computed costs. These variances can stem from different causes, and every business manager should look at the variances. To substitute the rest except a, we pick either the high or low point as reference. 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.

High-low Method in Accounting: Definition, Formula & Example

The following are the given data for the calculation of the high-low method. For example, the table below depicts the activity for a cake bakery for each of the 12 months of a given year. Take your learning and productivity to the next level with our Premium Templates.

Studies arising from HICs (as defined by a Human Development Index value of ≥0.700 [18] at the median year of data collection) must have at least 200 patients included in the study to increase the probability that at least one death may be recorded in the study. This requirement will be waived for LMICs due to the anticipated sparsity of data. Conditions requiring surgical treatment are highly prevalent worldwide, and unmet need for surgery accounts for approximately one-third of the global burden of disease [1–3].

Step 2: Calculate the Variable Cost Per Unit

• This eventual study may help policymakers and other key stakeholders with benchmarking surgical safety initiatives as well as identify key gaps in our current understanding of global perioperative mortality.
• This article describes the high-low method formula and how to use the high-low cost method calculator to estimate any business or production cost per unit.
• The fixed cost can be calculated once the variable cost per unit is determined.
• 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.
• But more importantly, this scenario shows the weakness of the high-low method.
• This is another advantage for this study to help reduce confounding and account for unexplained variation between studies [30].

In our previous dog groomer example we could clearly see through our scattergram that maintenance costs were related to the number of dogs groomed. Remember that that was our initial diagnostic step before we moved on to more detailed analysis of our costs. Data x represents the number of units while y represents the corresponding cost. Due to its unreliability, high low method should be carefully used, usually in cases where the data is simple and not too scattered.

Follow the steps below to perform the high-low method by using our sample data from Fusion Company. Let’s assume that the company wants to project client support costs for next year’s budgeting. The company claiming the making work pay tax credit plans to produce 7,000 units in March 2019 on the back of buoyant market demand. Help the company accountant calculate the expected factory overhead cost in March 2019 using the high-low method.

The high-low method involves taking the highest level of activity and the lowest level of activity and comparing the total costs at each level. The high-low method is a cost accounting technique that compares the total cost at the highest and lowest production level of business activity. It uses this comparison to estimate the fixed cost, variable cost, and a cost function for finding the total cost of different production units. In cost accounting, the high-low method formula refers to the mathematical technique used to separate fixed and variable components that are otherwise part of the historical cost that is mixed, i.e., partially fixed and partially variable.

Among the proposed metrics to capture data regarding the progress of establishing universal access to safe and affordable surgery POMR stands alone as the sole measure of patient safety. As such it is important for health systems to understand both the current rate of perioperative mortality as well as where such a rate fits into the broader historical trends. The secondary objective is to investigate cause-specific mortality in an attempt to understand the causes driving POMR. Data on causes will first be presented as overall proportions aggregated by type of surgery, time and HDI category wherever possible. Sankey diagrams will be used to better visualize changes over time in these proportions to provide a clearer picture of the impact of the causes on perioperative mortality.
