Study Notes

Cost Behavior & Its Importance

Cost behavior refers to how a cost changes in response to variations in the level of business activity.
Understanding cost behavior is essential for effective decision-making in planning and controlling a company's operations.
Planning involves making decisions based on expectations about the future, which are derived from relevant data.
Control involves using feedback information to compare actual performance with expectations and take corrective action.
Cost analysis is a crucial element of both planning and controlling.
Recognizing patterns in cost behavior is key to accurate cost predictions.

Types of Cost Behavior Patterns

Variable Costs: Costs that change in total as the level of activity changes within the relevant range.
- Defined as the short-run period where management can adjust production levels.
- The relevant range refers to the activity levels within which cost behavior assumptions are valid.
- The variable cost per unit remains constant within the relevant range.
- To be considered variable, a cost must vary directly with its activity base (the driver of the cost).
- Examples in manufacturing: direct materials, direct labor, and variable overhead.
- Examples in merchandising: cost of goods sold and sales commissions.
- Examples in service companies: direct labor and materials used to provide services.
Fixed Costs: Costs that remain constant in total regardless of changes in the level of activity within the relevant range.
- Can be affected by external factors like price changes.
- Fixed cost per unit changes inversely with activity levels – decreasing as activity increases and increasing as activity decreases.
- Types of fixed costs:
  - Committed Fixed Costs: Long-term investments in assets and organizational structure, such as depreciation, real estate taxes, insurance, and top management salaries.
    - Characterized by their long-term nature and difficulty in reducing significantly without impacting profitability.
    - Remain constant even if operations are temporarily halted.
  - Discretionary Fixed Costs (Managed Fixed Costs): Costs determined by annual management decisions, such as advertising, research, and public relations.
    - Flexible and adjustable based on current needs and circumstances.
    - Can be changed from year to year or even during the year if necessary.
    - Once budgeted, they are largely unaffected by actual activity levels.
Mixed Costs (Semi-Variable Costs): A combination of both variable and fixed cost elements.
- Examples: Maintenance costs and utility costs.

Cost Estimation Methods

Cost estimation aims to determine the relationship between costs and the factors that influence them.
Methods for estimating cost behavior:
- Account Analysis Method: Based on the experience and judgment of managers and accountants who are familiar with company operations.
  - Involves reviewing cost accounts and classifying them as fixed or variable.
  - Mixed costs are further divided into estimated variable and fixed components.
  - Advantage: Provides a detailed review of the data by experts within the company.
  - Disadvantage: Relies on subjective judgment, leading to potential variations in estimates by different analysts.
- Industrial Engineering Method: Analyzes the relationship between inputs and outputs in a physical form.
  - Applicable to both manufacturing and non-manufacturing companies.
  - Advantage: Provides a detailed understanding of each step in an operation, allowing assessment of productivity and identification of strengths and weaknesses.
  - Disadvantage: Can be expensive due to the need for engineering expertise. Difficulty in estimating indirect costs of production.
- Conference Method: Involves gathering cost information and opinions from various departments.
  - Advantage: Allows rapid development of cost functions and estimates.
  - Disadvantage: The accuracy of estimates depends on the objectivity and thoroughness of the information provided.
- Quantitative Analysis of Current and Past Cost Relationships: Utilizes statistical techniques to analyze historical data.
  - High-Low Method: Calculates the variable cost rate using the highest and lowest activity levels within the relevant range.
  - Regression Analysis: Employs all available data to estimate the cost function.
    - Simple regression: Analyzes the relationship between one dependent variable and one independent variable.
    - Multiple regression: Analyzes the relationship between one dependent variable and multiple independent variables.
    - Advantage: Utilizes a broad range of data to provide a more accurate estimate.
    - Disadvantage: Requires advanced statistical knowledge and can be complex to implement.
  - Least-Squares Regression Method: A statistical technique for separating mixed costs into their fixed and variable components.
  - Scattergraph (Visual Fit): A visual tool for plotting past cost data against activity levels.
    - Provides a visual assessment of cost behavior.
    - Advantage: Quick and easy to use.
    - Disadvantage: Provides a rough estimate and may not be accurate for all situations.

Correlation Analysis and Cost Estimation

Evaluating the correlation between selected factors and cost behavior is essential to ensure the factor's suitability for cost analysis.
The coefficient of determination measures the degree of correlation between activity levels and costs.
Establishing a cause-and-effect relationship between the cost driver and costs is crucial for accurate cost estimation.
A high correlation between two variables does not necessarily imply causality.
Economic plausibility reinforces confidence in the estimated relationship and its applicability to other similar data sets.

The Learning Curve Theory

Also known as the Improvement Curve Theory.
Based on the principle that as workers gain experience in a task, they become more efficient, and productivity increases.
The learning curve is a power function and appears as a straight line when plotted on double logarithmic paper.

Uses of the Learning Curve

Preparing cost estimates for bidding purposes.
Establishing standards and budget allowances.
Scheduling labor requirements.
Evaluating performance against anticipated progress under the learning curve.
Setting incentive wage rates, considering time reductions as workers gain experience.
