# Cost Behavior Analysis

For example, Bert pays his business insurance in January of each year. Bert’s annual insurance premium is \$10,800, which is \$900 per month. Each month, Bert will recognize 1/12 of this insurance cost as an expense in the period in which it is incurred (Figure 2.24). The Ocean Breeze is located in a resort area where the county assesses an occupancy tax that has both a fixed and a variable component.

• Fixed costs include things such as rent, insurance, salaries, and property taxes, which stay constant in your relative range.
• However, a manufacturing firm may carry product costs such as materials from one period to the other in order to have the costs “travel” with the units being produced.
• As a result, it may be necessary to analyze some fixed costs together with some variable costs.
• Other examples of committed fixed costs include salaried employees with long-term contracts, depreciation on buildings, and insurance.
• Not all costs can be classified as purely fixed or purely variable.

Cost behavior indicates how a cost will change when an activity changes. Therefore, the management could exercise and control expenses more effectively and increase the profit margin due to this concept’s effective application. Several expenses are incurred when manufacturing goods or rendering services.

## Policy and Managed Costs

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. Variable, fixed, and mixed cost concepts are useful for short-term decision making and therefore apply to a specific period of time. This short-term period will vary depending on the company’s current production capacity and the time required to change capacity. In the long term, all cost behavior patterns will likely change. On the other hand, if a company generates 1 million tiles, the fixed cost remains the same. In this case, variable costs change from zero to \$2 million because of the volume rise.

• The high point of activity is 75,000 gallons and the low point is 32,000 gallons.
• This takes your fixed costs beyond the relevant range and into the category of step costs, as the change in the way you do business creates extra expenses.
• Fixed costs are those who do not change .with the level of activity within the relevant range.
• This makes the slope of the line, the variable cost, \$0.25 (\$6,000 ÷ 24,000), and the fixed costs \$5,000.
• Therefore, the number of goods or services a firm produces does not impact the fixed expenditures.
• Administrative processes are one such aspect affected by changes in cost behavior.

Say your crochet company has a contract with a shipping company to transport its blankets. For this service, you pay a fixed cost of \$75 per month plus a variable cost of \$5 for every shipment you send, regardless of how many packages you submit for transport to customers. This means your crochet company incurs mixed costs for delivery of its blankets. The graphs for the fixed cost per unit and variable cost per unit look exactly opposite the total fixed costs and total variable costs graphs.

Firms typically use mathematical cost functions to study cost behavior. Using the solution from Example #2, calculate the fixed cost per do i need to file a tax return unit for 12,000 units. To calculate the total fixed overhead, multiply the rate by the number of units for which that rate applies.

“Profitability is just around the corner.” This is a common expression in the business world. Business is tough, profits are illusive, and competition has a habit of moving into areas where profits are available. Sometimes revenue growth only seems to bring on waves of additional expenses. Fixed cost is the cost that accrues about the passage of time and which, within certain limits, tends to be unaffected by fluctuations in the level of activity. Regression analysis or the method of least squares is ideally suited to cost behavior analysis. This method appears to be imposingly complex, but it is not nearly so complex as it seems.

## Everything You Need To Master Financial Statement Modeling

The food and lift ticket expenses are examples of variable costs, since they fluctuate based upon the number of participants and the number of days of activities. Once you incur a fixed cost, it does not change within a given range. For example, Pat can take up to five people in one car, so the cost of the car is fixed for up to five people. However, if he took more friends, then he would need more cars. The condo rental and the gasoline expenses would also be considered fixed costs, because they are not going to change in the reference range. Discretionary fixed costs generally are fixed costs that can be incurred during some periods and postponed during other periods but which cannot normally be eliminated permanently.

Having this information on hand especially helps when you wish to expand your operations. Other businesses have attempted to avoid fixed costs so that they can maintain a more stable stream of income relative to sales. For example, a computer company might outsource its tech support.

## cost behavior definition

Committed fixed costs are important because they cannot be avoided in lean times; discretionary fixed costs can be altered with proper planning. Consider that some fixed costs are committed fixed costs arising from an organization’s commitment to engage in operations. These elements include such items as depreciation, rent, insurance, property taxes, and the like. These costs are not easily adjusted with changes in business activity.

Could one estimate how much the bill should be for a particular level of usage? This type of problem is frequently encountered, as many expenses contain both fixed and variable components. One approach to sorting out mixed costs is the high-low method. It is perhaps the simplest technique for separating a mixed cost into fixed and variable portions. However, beware that it can return an imprecise answer if the data set under analysis has a rogue data point.

## Understanding Cost Behaviour Classifications

An example of a mixed cost or semi variable cost is the bakery’s cost of natural gas. Some of the monthly gas bill is a flat fee charged by the utility and some of the gas bill is the cost of heating the building. These two components of the gas bill are fixed since they will not change when the bakery produces more or less loaves of its bread. However, a third component of the gas bill is the cost of operating the ovens. This component is a variable cost since it will increase when the ovens must operate for a longer time in order to produce additional loaves of bread. This means that certain efficiencies are achieved as production levels rise.

Variable production costs will no longer be \$60 per unit, fixed production costs will no longer be \$20,000 per month, and mixed sales compensation costs will also change. All these costs will change because the estimates are accurate only in the short term. A fixed cost2 describes a cost that is fixed (does not change) in total with changes in volume of activity. Assuming the activity is the number of bikes produced and sold, examples of fixed costs include salaried personnel, building rent, and insurance.

Fixed costs can be spread over larger production runs, and this causes a decrease in the per unit fixed cost. In addition, enhanced buying power results (e.g., quantity discounts) as volume goes up, and this can reduce the per unit variable cost. These are valid considerations and must be taken into consideration in any business evaluation. However, care must also be exercised to limit one’s analysis to a “relevant range” of activity.

## One more step…

In other words, fixed costs remain fixed in total but can increase or decrease on a per-unit basis. Now that we have identified the three key types of businesses, let’s identify cost behaviors and apply them to the business environment. In managerial accounting, different companies use the term cost in different ways depending on how they will use the cost information. Different decisions require different costs classified in different ways.

Two of the most common drivers used in managerial accounting are units and hours, but there are lots of different drivers that could be used like customers or miles. If you can determine that a cost is driven by a particular activity, you can use that driver to calculate a variable cost. Any pricing data outside of this range is irrelevant and need not be considered. This enhanced concept of variable cost is portrayed in the accompanying graphic. The average variable cost will be \$70.00 per person per day, no matter how many people go on the trip.
