What is the High-Low Method?

While it is easy to apply, it can distort costs and yield more or less accurate results because of its reliance on two extreme values from one data set. By using the formula in computing the variable cost per unit, let’s substitute the figures we gathered from Step 1. Management accounting involves decision-making, planning, coordinating, controlling, communicating, and motivating. Similar to management accounting and financial accounting, there is cost accounting to determine the cost of a product.

The high-low method provides a simple way to split fixed and variable components of combined costs using a few formula steps. First you calculate the variable cost component and fixed cost component, then plug the results into the cost model formula. 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. 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.

  1. Waymaker Furniture has collected cost information from its production process and now wants to predict costs for various levels of activity.
  2. When creating the scatter graph, each point will represent a pair of activity and cost values.
  3. The two points are not representing the production cost at a normal level.
  4. 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.

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. For example, in the production cost of a product, fixed costs may comprise employee’s wages and rental expenses, whereas variable costs include costs incurred in purchasing raw materials. The variable cost per unit is equal to the slope of the cost volume line (i.e. change in total cost ÷ change in number of units produced). The process of calculating the estimated fixed costs and variable costs takes a step by step approach with the High-Low method. The highest and lowest activity levels are September at 300 client calls and October at 100 client calls.

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. Regression analysis is also best performed using a spreadsheet program or statistics program. The high low method excludes the effects of inflation when estimating costs.

Both of these costs have an impact on overall profitability and knowing each will help you make better decisions. Therefore, total fixed costs for client support calls is $1,500 per month. In the side-by-side computation above, we’ve proven our point that regardless of which reference point we use, we still arrive at $1,500. In scatter graphs, cost is considered the dependent variable because cost depends upon the level of activity.

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. Where Y is the total mixed cost, a is the fixed cost, b is the variable cost per unit, and x is the level of activity. iop intuit uses the lowest production quantity and the highest production quantity and comparing the total cost at each production level.

Being a new hire at the company, the manager assigns you the task of anticipating the costs that would be incurred in the following month (September). 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 can be relatively accurate if the highest and lowest activity levels are representative of the overall cost behavior of the company. However, if the two extreme activity levels are systematically different, then the high low method will produce inaccurate results. Thus, it calculates the variable costs where the linear correlation holds true. Like any other theoretical method, the High-Low method of cost allocation also offers some limitations.

What Is the High-Low Method?

The fixed cost is calculated by subtracting the variable cost for the average activity level from the total average cost. Fixed costs can be found be deducting the total variable cost for a given activity level (i.e. 6000 or 4000) from the total cost of that activity level. 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. 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. Waymaker Furniture has collected cost information from its production process and now wants to predict costs for various levels of activity.

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. Likewise, if variable costs per unit change, these must also be adjusted. In many cases, the variable costs identified under the high-low method can be different from other cost methods.

What are the risks of the high-low method?

An example of a relevant cost is future cost and opportunity cost, whereas irrelevant cost is sunk cost and committed cost. Relevant/ Irrelevant costs – These are also known as avoidable and unavoidable costs. Avoidable costs are the ones that are affected by the decision of a manager, whereas unavoidable costs are costs that are not affected by the decision of managers. It is commonly practiced to assist managers in making crucial business decisions, as it provides them with actual statistics and critical data that help with decisions. A cost is an expense needed to sell, create or acquire assets for a product or service.

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

The high-low method in accounting is the simplest and easiest way to separate mixed costs into their fixed and variable components. By using this method, we observe only the highest and lowest points in the data set with the assumption that all the data have a linear relationship. We use the high-low method accounting formula to calculate the variable unit per cost as the change in total cost divided by the change in units produced (or other measure of activity). 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.

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 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. The first step is to determine the highest and lowest levels of activities and the units produced against each of these levels. To separate the fixed cost element from the variable cost element the high low method can be used.

Their role is to collect, observe, and record numbers; advise on the company’s investments and manage them; budgeting, planning, risk management, and decision-making.

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.

Cost accounting also helps in minimizing product costs as it highlights the reports of profit. She has been assigned the task of budgeting payroll costs for the next quarter. 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.

By only requiring two data values and some algebra, cost accountants can quickly and easily determine information about cost behavior. Also, the high-low method does not use or require any complex tools or programs. The first step in analyzing mixed costs with the high-low method is to identify the periods with the highest and lowest levels of activity.

For example, the electricity cost for a firm will increase when working hours are increased. Management accounting refers to identifying, analyzing, and communicating financial information to a firm’s managers to achieve the company’s future goals. To understand the high-low method, first, we need to understand management accounting.
