The high low method accounting formula states that the variable cost per unit is equal to the change in cost between the high and low cost values divided by the change in units between the same values. 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. Given the variable cost per number of guests, we can now determine our fixed costs. The company plans to produce 7,000 units in March 2019 on the back of buoyant market demand.

The part of the electric bill that does not change with the number of machine hours is known as the fixed cost. The high low method has allowed a total cost to be split into variable and fixed cost components. In the example above the variable cost per unit is 5.00 and fixed costs are 40,000. The hi low method now takes the highest and lowest activity cost values and looks at the change in total cost compared to the change in units between these two values.

- He has worked as an accountant and consultant for more than 25 years and has built financial models for all types of industries.
- By only requiring two data values and some algebra, cost accountants can quickly and easily determine information about cost behavior.
- 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.
- The underlying concept of the method is that the change in the total costs is the variable cost rate multiplied by the change in the number of units of activity.

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.

## High Low Variable Cost Formula

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. 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. 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.

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. 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.

The underlying concept of the method is that the change in the total costs is the variable cost rate multiplied by the change in the number of units of activity. The cost of electricity was $18,000 in the month when its highest activity was 120,000 machine hours (MHs). (Be sure to use the MHs that occurred between the meter reading dates appearing on the bill.) The cost of electricity was $16,000 in the month when its lowest activity was 100,000 MHs. This shows that the total monthly cost of electricity changed by $2,000 ($18,000 vs. $16,000) when the number of MHs changed by 20,000 (120,000 vs. 100,000). In other words, the variable cost rate was $0.10 per machine hour ($2,000/20,000 MHs). The fixed cost is determined by calculating the variable costs using the rate calculated above and the number of units, and deducting this from the total cost.

The high-low method assumes that fixed and unit variable costs are constant, which is not the case in real life. Because it uses only two data values in its calculation, variations in costs are not captured in the estimate. 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. It is possible for the analysts and accountants to use this method effectively for determining both the fixed and variable cost component. However, it does assume that the fixed costs are actually fixed throughout this range of values, and this can lead to inaccurate results if the high or low values used happen to be exceptions to the general trend of the data. Simply adding the fixed cost (Step 3) and variable cost (Step 4) gives us the total cost of factory overheads in April.

The high-low method is relatively unreliable because it only takes two extreme activity levels into consideration. The high or low points used for the calculation may not be representative of the costs normally incurred at those volume levels due to outlier costs that are higher or lower than would normally be incurred. 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.

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. Given the dataset below, develop a cost model and predict the costs that will be incurred in September.

This calculation can be done using either the high or low values, but both are shown below for comparison. 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. It is worth being cautious when using the high-low method, however, as it can yield more or less accurate results depending on the distribution of values between the highest and lowest dollar amounts or quantities. The high-low method is a simple technique for determining the variable cost rate and the amount of fixed costs that are part of what’s referred to as a mixed cost or semivariable cost.
