Chapter : 4 Overheads – Absorption Costing Method

Overview

• Understanding overhead costs and their significance in the manufacturing process.
• Importance of accurately allocating and absorbing overheads for cost computation and decision making.
• Methods for classification, allocation, apportionment, and absorption of overheads.
• Explanation of under-absorption and over-absorption of overheads and their impact on financial statements.
• Tools and techniques for the accounting and control of different types of overhead costs.

Key Topics

Meaning and Classification of Overheads

• Overheads are indirect costs that cannot be traced directly to a specific cost unit, such as factory rent, utilities, and salaries of supervisory staff.
• Classification by function includes manufacturing, administrative, and selling & distribution overheads.
• Manufacturing overheads encompass costs such as factory supplies, repairs, and indirect labor related to the production of goods.
• Administrative overheads involve costs for management, general services, and office supplies that do not tie directly to manufacturing.
• Selling and distribution overheads cover costs involved in marketing, sales, and distribution of products.

Deep Dive

• Discussions of fixed, variable, and semi-variable overheads, and their impact on budgeting and forecasting.
• Understanding direct vs indirect costs, and how they affect pricing and profit calculations.
• Real-world applications and examples of each category of overhead in diverse industries.

Cost Allocation and Apportionment

• Allocation refers to assigning an entire item of cost to a specific cost center, while apportionment divides costs across multiple centers based on a relevant basis.
• Examples include direct labor costs being allocated directly to production, while rent might be apportioned based on floor space occupied by each department.
• Selection of apportionment bases such as number of employees, machine hours, and production volume is critical for accurate cost distribution.
• Methods of allocation and apportionment help ensure that all indirect expenses are fairly distributed among production activities.

Deep Dive

• Case studies illustrating the importance of selecting appropriate bases for allocation, and the implications of poor choices on cost assessment.
• Advanced concepts of dual allocation methods for shared resources between departments.
• Debating common challenges faced by accountants in ensuring fairness during allocation.

Absorption of Overheads

• Absorption refers to the method of charging overheads to products based on predetermined rates, which must be established before the accounting period begins.
• There are various methods to calculate absorption rates, including direct labor hours, machine hours, and total cost percentages.
• Regular review and adjustment are necessary to align absorbed overheads with actual costs incurred, and discrepancies lead to under or over absorption.
• Absorption rates should reflect actual production capacity and efficiency to improve financial reporting accuracy.

Deep Dive

• Understanding the principles behind setting predetermined overhead rates and the impact of changes in production capacity on these rates.
• Role of capacity utilization in costing; examining fixed vs variable overheads in relation to production volume.
• Examples of corrective actions for significant variances between absorbed and actual overhead costs.

Under and Over Absorption of Overheads

• Under-absorption occurs when the overheads applied to products are less than the actual overheads incurred.
• Over-absorption is the opposite situation where applied overheads exceed actual incurred costs, leading to surplus in accounts.
• Both cases require careful accounting treatment; minor discrepancies are often transferred to the Costing Profit & Loss Account.
• Supplementary rates may be calculated to adjust the cost allocations for unsold stock and work in progress.

Deep Dive

• Real-world examples of how companies handle significant under or over absorption in their financial statements.
• Detailed implications of misallocation effects on broader financial reports and strategic decision-making.
• Discussions on optimal practices for regular reviews and adjustments throughout the accounting period.

Accounting and Control of Overheads

• Establishing a systematic approach to monitor and control overheads within departments ensures efficiency and cost-effectiveness.
• Effective use of budgeting and standard costing techniques allows for essential control measures against actual spending.
• Management should focus on operational variances between budgeted and actual figures to identify areas needing intervention.
• Tools like flexible budgets and variance analysis play an integral part in fine-tuning ongoing overhead controls.

Deep Dive

• Exploring advanced techniques in overhead management such as activity-based costing (ABC) for more precise overhead allocation.
• Understanding the strategic importance of overhead control for long-term financial health and competitive advantage.
• Real-world performances and case studies of successful overhead cost management initiatives.

Methods to Calculate Overhead Rate

• Common methods include percentages based on direct costs, hourly machine rates, and specific job-based allocations of overheads.
• Each method has variations based on operational context, production processes, and management structures of an organization.
• It is crucial to continually evaluate the chosen methods for their effectiveness in delivering accurate cost information.

Deep Dive

• In-depth analysis of the appropriateness of each overhead rate method depending on various operational scales.
• Discussing hybrid methods combining several principles to suit complex manufacturing environments.
• Critical examination of how innovative technologies influence overhead calculation methodologies.

Summary

Overheads are crucial components of manufacturing, representing indirect expenditures that facilitate production processes but do not tie directly to specific products. This comprehensive overview covers the classification of overheads into manufacturing, administrative, and selling & distribution categories, as well as the methodologies for allocation, apportionment, and absorption, highlighting significant implications of under and over absorption. Strategies for accounting and controlling overheads are elaborated upon with various methods for calculating overhead rates—their suitability, effectiveness, and advancements in practice are explored. Through understanding these concepts, students and professionals can make informed decisions that optimize cost management in manufacturing operations.
