    • Factory Cost
    • Administrative Expenses
  • Importance: Provides a comprehensive view of the total cost incurred to produce goods, including administrative overheads.

d. Total Cost or Cost of Sales

  • Definition: Cost of production plus selling and distribution overheads.
  • Components:
    • Cost of Production
    • Selling and Distribution Overheads
  • Importance: Represents the complete cost involved in selling goods and distributing them, critical for profit margin analysis and pricing strategies.

3. Classification of Costs by Behaviour

a. Variable Costs

  • Definition: Costs that vary directly with the level of production or sales volume.
  • Examples: Direct materials, direct labor, utility costs for production.
  • Importance: Helps in budgeting and cost control, especially in scaling production.

b. Fixed Costs

  • Definition: Costs that remain constant regardless of production levels.
  • Examples: Rent, salaries of permanent staff.
  • Importance: Important for long-term financial planning and analysis, as these costs do not change with production levels.

c. Semi-variable Costs

  • Definition: Costs that have both fixed and variable components.
  • Examples: Utility bills with a fixed monthly charge plus a variable charge based on usage.
  • Importance: Helps in understanding costs that fluctuate but not in direct proportion to production changes.

4. Classification of Costs for Managerial Decisions and Control

a. Controllable and Uncontrollable Costs

  • Controllable Costs: Costs that can be influenced or managed by a specific individual or department.
    • Examples: Departmental expenses, discretionary spending.
    • Importance: Enables managers to take actions to manage or reduce costs within their control.
  • Uncontrollable Costs: Costs that cannot be influenced by the actions of a particular individual or department.
    • Examples: Corporate overheads, regulatory costs.
    • Importance: Helps in distinguishing between costs that can be managed versus those that cannot.

b. Normal and Abnormal Costs

  • Normal Costs: Costs that are typically incurred under normal operating conditions.
    • Examples: Standard utility costs, regular maintenance expenses.
    • Importance: Provides a benchmark for expected costs under normal conditions.
  • Abnormal Costs: Unusual or unexpected costs that do not typically occur under normal operations.
    • Examples: Unexpected repair costs due to a machine breakdown.
    • Importance: Identifying these helps in addressing issues that deviate from the norm and planning for contingencies.

c. Avoidable and Unavoidable Costs

  • Avoidable Costs: Costs that can be eliminated if a particular activity is discontinued.
    • Examples: Costs of producing a product line that is being phased out.
    • Importance: Helps in making decisions about discontinuing activities or products.
  • Unavoidable Costs: Costs that will continue even if a particular activity is discontinued.
    • Examples: Lease payments on rented premises.
    • Importance: Essential for understanding which costs will persist regardless of operational changes.

d. Shut Down and Sunk Costs

  • Shut Down Costs: Costs that are incurred when production is temporarily halted.
    • Examples: Maintenance costs during downtime.
    • Importance: Important for understanding the costs associated with stopping and restarting production.
  • Sunk Costs: Costs that have already been incurred and cannot be recovered.
    • Examples: Past advertising expenses, research costs.
    • Importance: Should not influence future decisions as they cannot be altered by current choices.

e. Product and Period Costs

  • Product Costs: Costs that are associated directly with the production of goods.
    • Examples: Raw materials, direct labor.
    • Importance: Essential for calculating the cost of goods sold and valuing inventory.
  • Period Costs: Costs that are not directly tied to production and are expensed in the period in which they are incurred.
