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

To properly budget or manage your business activities, you must know the fixed and variable costs required for its operation. This means that the variable cost per unit and total fixed cost will remain the same no matter the level of activity. 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.

• You need to know what the expected amount of overheads that your production line will incur in the next month.
• Since the number of oil changes is a consistent, reliable measure, we should use that to determine the high and low points.
• It only requires the high and low points of the data and can be worked through with a simple calculator.

Since we know that the variable cost of 750 oil changes is \$1,725, we can divide to calculate the variable rate. Because of the preceding issues, the high-low method does not yield overly precise results. Multiple regression is a statistical technique that predicts the value of one variable using the value of two or more independent variables. Once each of the independent variables has been determined, they can be used to predict the amount of effect that the independent variables have on the dependent variable. The effect is represented on a straight line to approximate each of the data points.

Now, the Beach Inn can apply the cost equation in order to forecast total costs for any number of nights, within the relevant range. 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. It is a nominal difference, and choosing either fixed cost for our cost model will suffice. High Low method will give us the estimation of fixed cost and variable cost, the result may be changed when the total unit and cost of both point change. The highest activity level is 18,000 in Q4, and the lowest activity level is 10,000 in Q1.

## Is the high low method the only method for estimating fixed and variable costs?

The high low method uses a small amount of data to separate fixed and variable costs. It takes the highest and lowest activity levels the systemic implications of bail and compares their total costs. On the other hand, regression analysis shows the relationship between two or more variables.

• Let’s take a more in-depth look at the cost equation by examining the costs incurred by Eagle Electronics in the manufacture of home security systems, as shown in Table 2.9.
• 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.

The company would like you to write a mixed cost formula for planning purposes. It might seem daunting at first but it’s really a lot easier than you might think. 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. 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. The fixed cost can then be calculated at the specific activity level i.e. either high level or low level of activity. The high-low method calculator will help you find the variable cost per unit, fixed cost, and cost-volume model for your business operation with ease.

When using this approach, Eagle Electronics must be certain that it is only predicting costs for its relevant range. 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. 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. In many cases, the variable costs identified under the high-low method can be different from other cost methods.

## Step 2: Calculate the Variable Cost Per Unit

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. You can then use these estimates in preparing your budgets or analyzing an expected monetary value for a contingency reserve. Please check out our EMV calculator to understand more on this topic.

High Low Method provides an easy way to split fixed and variable components of combined costs using the following formula. The high low method determines the fixed and variable components of a cost. It can be applied in discerning the fixed and variable elements of the cost of a product, machine, store, geographic sales region, product line, etc. 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.

## Example of the High-Low Method of Accounting

This can be remedied by redoing the computation if there are any changes within the costs. The high-low method also does not take into account any changes within the costs (e.g. increase in the price of raw materials, rent, etc.). The thing is, Allen became too involved with his other businesses that he wasn’t able to monitor the costs of his donut shop. As such, it may distort your cost data, especially if there are outliers within the set of data. It is a simple technique that can be used even with a limited set of data.

The high-low method is a quick and simple way to segregate variable and fixed costs. Using the high-low method, we gather that the variable cost is \$10 per unit, and the total fixed cost is \$17,500. As can be seen from the set of data above, the highest value is at 4,915 units and \$83,235 total costs.

## Demonstration of the High-Low Method to Calculate Future Costs at Varying Activity Levels

Here we will demonstrate the scatter graph and the high-low methods (you will learn the regression analysis technique in advanced managerial accounting courses. The high-low method is used to calculate the variable and fixed cost 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.

Since you have the total cost equation now, you can use this to calculate your cost any month. The high-low method is a straightforward, if not slightly lengthy, way to figure out your total costs. The first step is to determine the highest and lowest levels of activities and the units produced against each of these levels.

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

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. In any business, three types of costs exist Fixed Cost, Variable Cost, and Mixed Cost (a combination of fixed and variable costs). Given the variable cost per number of guests, we can now determine our fixed costs. We’ll take a closer look at how you can utilise this technique and learn how to estimate your fixed and variable costs.

Although the high-low method is easy to apply, it is seldom used because it can distort costs, due to its reliance on two extreme values from a given data set. 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 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.

Even if you own the building that houses your operations, you’d still incur costs in the form of depreciation. You might be wondering how we are going to jump to solving for the variable rate when it doesn’t seem like we have a whole lot of information. Due to its unreliability, high low method should be carefully used, usually in cases where the data is simple and not too scattered. For complex scenarios, alternate methods should be considered such as scatter-graph method and least-squares regression method.
