Overhead Analysis Sheet: Distribution Summary of Manufacturing Overheads

August 31, 2024 5 min read Accounting Finance Overhead Costs Cost Centers Allocation Apportionment Cost Accounting

An overhead analysis sheet is a crucial tool in cost accounting, where the manufacturing overhead is systematically charged to different cost centers of an organization by utilizing various allocation or apportionment techniques.

An Overhead Analysis Sheet serves as a detailed form that facilitates the charging of manufacturing overhead costs to the appropriate cost centers within an organization. This is accomplished through allocation or apportionment techniques tailored to each item of overhead cost. Understanding and efficiently using an overhead analysis sheet is essential for accurate cost accounting and budgeting in any manufacturing environment.

Historical Context

The concept of overhead costs and their distribution dates back to the early 20th century, when industrialization increased the complexity of manufacturing processes. As businesses grew, so did the need for detailed financial tracking and cost management. The overhead analysis sheet emerged as a tool to systematically allocate indirect costs to the relevant parts of the organization, improving financial accuracy and operational efficiency.

Types/Categories of Overhead Costs

Fixed Overheads: Costs that remain constant regardless of production volume, such as rent, salaries, and insurance.
Variable Overheads: Costs that fluctuate with production levels, like utility costs and raw materials.
Semi-variable Overheads: Costs containing both fixed and variable components, such as maintenance expenses and telephone bills.

Key Events in Overhead Cost Management

1913: Henry L. Gantt introduces the Gantt chart, highlighting the importance of detailed scheduling and cost tracking.
1923: The concept of the standardized costing system is popularized by Harrington Emerson, advocating for systematic overhead cost allocation.
1950s: The rise of Activity-Based Costing (ABC), which emphasizes the allocation of overhead costs based on activities that drive those costs.

Detailed Explanation of Overhead Analysis Sheet

An overhead analysis sheet typically involves several steps:

Identification of Overhead Costs: Cataloging all indirect costs associated with production.
Selection of Allocation Bases: Choosing appropriate methods to allocate these costs (e.g., machine hours, labor hours).
Apportionment of Costs: Distributing costs across different departments or cost centers based on predetermined allocation bases.

Importance and Applicability

Accurate Costing: Ensures precise allocation of indirect costs, facilitating true product cost estimation.
Budgeting: Helps in forming realistic budgets by accounting for all overhead costs.
Financial Reporting: Enhances the accuracy of financial statements, aiding in compliance and decision-making.
Performance Measurement: Assists in evaluating departmental efficiency by comparing allocated overhead with actual spending.

Examples of Overhead Analysis Sheet

Example 1: Basic Manufacturing Scenario

Consider a factory with the following overhead costs:

Rent: $10,000
Utilities: $5,000
Maintenance: $2,500

Cost centers include:

Department A (30% of total usage)
Department B (50% of total usage)
Department C (20% of total usage)

Allocation:

1Department A: (30% of $17,500) = $5,250
2Department B: (50% of $17,500) = $8,750
3Department C: (20% of $17,500) = $3,500

Charts and Diagrams

    pie title Overhead Allocation
	    "Department A": 5250
	    "Department B": 8750
	    "Department C": 3500

Considerations

Selection of Allocation Base: Choosing an inappropriate base can lead to distorted cost allocation.
Variability of Costs: Understanding the nature of costs (fixed, variable, semi-variable) is essential for accurate allocation.
Regular Updates: Overhead costs and allocation bases should be reviewed periodically to ensure accuracy.

Allocation: The process of assigning a cost, or a group of costs, to one or more cost objects.
Apportionment: The distribution of overhead costs to several cost centers or departments.
Cost Center: A part of an organization to which costs can be charged.

Comparisons

Direct Costs vs. Overhead Costs: Direct costs are directly attributable to a product, while overhead costs are indirect.
Activity-Based Costing (ABC) vs. Traditional Costing: ABC allocates overhead more accurately by focusing on activities that incur costs, whereas traditional costing may use simplistic allocation bases.

Interesting Facts

The use of overhead analysis sheets can date back to the industrial revolution, where meticulous tracking of indirect costs helped in cost reduction and efficiency improvement.

Inspirational Stories

Toyota Production System (TPS): By rigorously analyzing overhead costs and employing lean manufacturing principles, Toyota managed to reduce waste and improve efficiency, becoming a global leader in the automotive industry.

Famous Quotes

“You can’t manage what you can’t measure.” – Peter Drucker

Proverbs and Clichés

“Penny-wise and pound-foolish”: Emphasizes the importance of not neglecting overhead costs while trying to save direct costs.

Expressions, Jargon, and Slang

[“Overheads”](https://financedictionarypro.com/definitions/o/overheads/ ““Overheads””): Colloquial term for overhead costs.
[“Absorption costing”](https://financedictionarypro.com/definitions/a/absorption-costing/ ““Absorption costing””): A method where all manufacturing costs, including overheads, are absorbed by units produced.

FAQs

What is the main purpose of an overhead analysis sheet?

It helps in the systematic allocation and apportionment of overhead costs to relevant cost centers to ensure accurate product costing and financial reporting.

How often should overhead analysis sheets be updated?

They should be reviewed and updated periodically, ideally monthly or quarterly, to ensure the allocation bases remain accurate and relevant.
