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. Given the dataset below, develop a cost model and predict the costs that will be incurred in September. The next step is to calculate the variable cost element using the following formula. No, there are other methods apart from the high-low method accounting formula.

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. One of the assumptions that managers must make in order to use the cost equation is that the relationship between activity and costs is linear. A diagnostic tool that is used to verify this assumption is a scatter graph.

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. 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. 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.

## Step 02: Calculate the variable cost element

Yes, because it is a simple tool to compute costs at different activity levels. It can also be used for budgeting purposes, especially for business activities with fixed and variable components. In many cases, the variable costs identified under the high-low method can be different from other cost methods. The direct costing methods of calculating the variable cost per unit provide accurate figures that consider costs related to the production. Also, the mean or the average variable cost per unit for longer periods can provide more realistic figures than taking extreme activity levels.

1. Over 1.8 million professionals use CFI to learn accounting, financial analysis, modeling and more.
2. For the months from June to August, the actual costs are always higher than the computed costs.
3. The highest and lowest activity levels are September at 300 client calls and October at 100 client calls.
4. The high-low accounting method estimates these costs for different production levels, mainly if you have limited data to inform your decisions.
5. The next step is to calculate the variable cost element using the following formula.

The high-low accounting method estimates these costs for different production levels, mainly if you have limited data to inform your decisions. 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. When creating the scatter graph, each point will represent a pair of activity and cost values. Maintenance costs are plotted on the vertical axis (Y), while flight hours are plotted on the horizontal axis (X).

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. Estimation is also what is the difference between rent receivable and rent payable 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.

## Demonstration of the Scatter Graph Method to Calculate Future Costs at Varying Activity Levels

For example, the least-squares regression is a method that takes into consideration all data points and creates an optimized cost estimate. It can be easily and quickly used to yield significantly better estimates than the high-low method. The high-low method involves three main steps to calculate the cost for any level of production. Using the maintenance cost data from Regent Airlines shown in Figure 2.32, we will examine how this method works in practice.

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. In that case, the high-low method calculator applies the high-low method formula to evaluate the total costs at any given amount of production.

## The High Low Method: How to Split Variable and Fixed Costs

By using the formula in computing the variable cost per unit, let’s substitute the figures we gathered from Step 1. We can calculate the variable cost and fixed cost components by using the High-Low method. Only when there is a relationship between the activity and that particular cost. What if, instead, the cost of snow removal for the runways is plotted against flight hours?

As you can see from the scatter graph, there is really not a linear relationship between how many flight hours are flown and the costs of snow removal. This makes sense as snow removal costs are linked to the amount of snow and the number of flights taking off and landing but https://www.quick-bookkeeping.net/prepaid-property-taxes-deduction/ not to how many hours the planes fly. J&L wants to predict their total costs if they complete 25 corporate tax returns in the month of February. Therefore, even though we have zero client support calls, we still incur \$1,500 client support costs because these are fixed costs.

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. 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.
