Accounting L6: Costing (Definition, Classification + Absorption Costing)

Concept of Cost

Definition: Cost is defined as a resource sacrificed or foregone to achieve a specific objective.

  • Expression: Cost can also be seen as expenditure incurred.

  • Variability: Different answers exist based on context:

    • Historical cost vs. replacement cost

    • Full cost vs. marginal cost

    • Actual costs vs. budgeted costs

  • Consideration: The appropriate costing method depends on the decision being made.


Costing: Definition and Purposes

  • CIMA 2005 Definition: Gathering cost information and attaching it to cost objects.

  • Purpose:

    • Decision Making: Establish appropriate pricing for products or services.

    • Tendering: Accurate future cost estimates necessary for project bidding.

    • Short-Term Decisions: Considerations for accepting discounted orders while not at full capacity.

    • Financial Accounts: Essential for inventory valuation in annual reports.


Cost Classification

  • By Function: Differentiating costs related to production, marketing, research, and administration.

  • By Element: Classification with respect to material, labor, and overheads.

  • By Nature: Categories based on specific characteristics of the costs.

  • By Behavior: Classification into:

    • Direct Costs: Costs traceable to a specific cost object.

    • Indirect Costs: Costs associated with a cost object but non-traceable economically.


Direct and Indirect Costs

  • Direct Costs: Related to a specific cost object (product or department) and traceable.

  • Indirect Costs: Related but non-traceable in an economically feasible way.


Case Study: Limited Ltd

  • Departments:

    • Production: Assembly and Finishing

    • Service: Maintenance and Personnel

  • Direct Costs:

    • Assembly Department: €70,000

    • Finishing Department: €50,000

  • Indirect Costs:

    • Maintenance Department: €40,000

    • Personnel Department: €24,600

  • Cost Allocation: Maintenance costs allocated equally among production departments.


Breakdown of Costs by Type

  • Direct Costs Examples:

    • Factory materials

    • Labor

    • Overhead

    • Cost Breakdown:

      • Prime Cost: All direct costs.

      • Conversion Cost: associated conversion of prime inputs into finished goods.


Absorption Costing

  • Definition: Method to obtain the full cost of a product or service.

  • Usage: Inventory valuation in financial reports; basis for determining product price.


Example: Sponge and Chocolate**

  • Departments: 3 departments - 2 production (Sponge and Chocolate) and 1 service (Maintenance).

  • Prime Costs:

    • Sponge Cakes: £35 for 10,000 produced.

    • Chocolate Cakes: £42 for 8,000 produced.

  • Overheads:

    • Indirect ingredients: Distributed costs based on production volume.

    • Building costs: Allocated based on area.


Allocation of Building Costs

  • ** Cost Apportionment Method**:

    • Indirect building costs based on department area.

    • Building costs: £30,000 allocated based on square meters occupied.


Final Cost Analysis

  • Sponge Cakes Total Product Cost Calculation:

    • Total Overhead = Indirect ingredients + Building costs = £31,200

    • Cost per Sponge Cake = Total Overhead / Number Produced = £3.12

    • Total Product Cost = Prime Cost + Overhead = £38.12

  • Chocolate Cakes Total Product Cost Calculation:

    • Building costs proportionate based on overheads and direct costs:

    • Total Product Cost = Prime Cost + Overhead = £45.35


Pricing Considerations

  • Inventory valuations in annual reports for sponge (£38.12) and chocolate cakes (£45.35).

  • Pricing strategy will involve adding a percentage for non-production costs and a profit margin.


Overhead Absorption for Multiple Production Centers

  • Example of applying different methods for overhead absorption, including machine hours and labor hours.

  • Tennis Racquets Example:

    • Production in departments for distinct processes;

    • Costs are distributed based on actual production requirements across departments.
