Chapter Summary

The contents list shows twenty-four chapters in about 1,000 pages. Pearson describes the book as organised around the theme of "different costs for different purposes" and as treating cost accounting as a tool for business strategy rather than a set of procedures. The sequence runs from cost terms and cost-volume-profit analysis through costing systems, budgets and variances, decisions and strategy, cost allocation, and finally control and performance measurement.

Chapters 1–3: The Manager and Management Accounting; An Introduction to Cost Terms and Purposes; Cost–Volume–Profit Analysis

The opening chapters place management accounting in the manager's work, set out the vocabulary of costs and the purposes they serve, and introduce cost-volume-profit analysis.

Chapters 4–5: Job Costing; Activity-Based Costing and Activity-Based Management

Two chapters on how costs are assigned to products and jobs, moving from job costing to activity-based costing and its use in management.

Chapters 6–8: Master Budget and Responsibility Accounting; Flexible Budgets, Direct-Cost Variances, and Management Control; Flexible Budgets, Overhead Cost Variances, and Management Control

The planning and control block: the master budget and responsibility accounting, then flexible budgets with variances, divided into direct-cost variances and overhead variances.

Chapters 9–11: Inventory Costing and Capacity Analysis; Determining How Costs Behave; Data Analytic Thinking and Prediction

Inventory costing and capacity come first, then cost behaviour. Pearson says Chapter 11 was revised in this edition to clarify uses of big data and modern analytic techniques to manage revenue and costs.

Chapters 12–14: Decision Making and Relevant Information; Strategy, Balanced Scorecard, and Strategic Profitability Analysis; Pricing Decisions and Cost Management

Relevant information for decisions, the link from strategy to the balanced scorecard, and pricing together with cost management.

Chapters 15–17: Cost Allocation, Customer-Profitability Analysis, and Sales-Variance Analysis; Allocation of Support-Department Costs, Common Costs, and Revenues; Cost Allocation: Joint Products and Byproducts

A block on allocation: to customers, from support departments, and across joint products and byproducts.

Chapters 18–19: Process Costing; Spoilage, Rework, and Scrap

Process costing, followed by the costs of spoilage, rework and scrap.

Chapters 20–22: Balanced Scorecard: Quality and Time; Inventory Management, Just-in-Time, and Simplified Costing Methods; Capital Budgeting and Cost Analysis

Quality and time performance, inventory management and just-in-time, and capital budgeting.

Chapters 23–24: Management Control Systems, Transfer Pricing, and Multinational Considerations; Performance Measurement, Compensation, and Multinational Considerations

The closing chapters on control systems, transfer pricing, performance measurement and compensation, each with multinational considerations. Pearson says a new running example in Chapter 23, based on a pharmaceutical company, illustrates why technology firms often hold intellectual property abroad.

Key Concepts

Chapters 1–8: Cost Terms, Costing Systems, Budgets and Variances

• Different costs for different purposes: the publisher's stated theme, that the cost measure should fit the decision.
• Cost-volume-profit analysis: how costs and profit change with volume.
• Activity-based costing and management: assigning costs through activities and using that information in management.
• Flexible budgets and variances: comparing results with budgets adjusted to actual activity, separately for direct costs and overheads.

Chapters 9–17: Capacity, Decisions, Strategy and Allocation

• Cost behaviour: how costs respond to changes in activity.
• Relevant information: the information that matters for a particular decision.
• Balanced scorecard: a strategy-linked set of performance measures, with a second chapter on quality and time.
• Joint products and byproducts: allocating the common costs of simultaneous outputs.

Chapters 18–24: Process Costing, Capital Budgeting and Control

• Process costing; spoilage, rework and scrap: costing for continuous production and the cost of defects.
• Capital budgeting: analysing long-term investment.
• Transfer pricing: pricing between units of one organisation.
• Compensation: the link between performance measures and pay.

Critical Analysis

Strengths

• A single organising idea. The "different costs for different purposes" theme gives the long sequence of chapters a common question: which cost measure suits which decision.
• Teaching devices throughout. Pearson lists chapter-opening vignettes (the new edition adds IKEA's costing strategies), Concepts in Action boxes, Try It! exercises after concepts or calculations, and end-of-chapter problems.
• Current topics. The edition adds generative AI, the effects of the pandemic, sustainability material such as carbon-emission laws, and examples from merchandising and service businesses, such as budgeting for a furniture retailer and performance in a hotel chain.
• Modular and flexible. Pearson says the modules can be adapted to a course's needs, which suits instructors and readers who do not follow the book end to end.

Limitations

• Too long for one term. Twenty-four chapters and roughly 1,000 pages exceed a single course, so readers must choose.
• Late placement of some costing topics. Process costing and the treatment of spoilage, rework and scrap come in Chapters 18–19, after budgeting, decisions and strategy. A course that teaches product costing first will need to reorder.
• Not a first accounting book. Pearson positions the text for undergraduate and MBA courses in cost accounting or management accounting, so a first accounting course is a sensible prerequisite.
• US-oriented practice material. Pearson's MyLab features include Becker questions in the CPA exam format, which are relevant mainly to the US credential, and the examples refer to the US and global economy.

Where It Fits in the Course

Horngren sits in the middle of this management accounting course. Below it are two first courses: OpenStax's Principles of Accounting, Volume 2: Managerial Accounting, a free text moving from cost concepts to budgeting, variance analysis and capital investment, and Seal and Rohde's Management Accounting, a UK and European adaptation of Garrison and Noreen for students meeting the subject for the first time.

At the same level, Drury and Tayles's Management and Cost Accounting is a UK text across the whole field, written with professional examinations in mind; Horngren is the alternative for readers who want the strategy-linked, US-oriented framing. Atrill and McLaney's Management Accounting for Decision Makers is another alternative, with chapters on relevant costs, cost-volume-profit analysis and full costing. Merchant and Van der Stede's Management Control Systems is a graduate text built on results, action, personnel and cultural controls; it overlaps with Horngren's last two chapters and goes much deeper into them.

How to Use This Book

The book suits undergraduates and MBA students in a cost or management accounting course, and practitioners who want a reference on costing, budgeting and performance measurement. Come to it after a first course in financial and managerial accounting.

A practical reading plan:

• Core: Chapters 1–3, 4–5, 6–8, 12–14 and 22, which cover cost terms, costing systems, budgets and variances, decisions, pricing and investment.
• Read next to the core: Chapter 10 on cost behaviour fits beside Chapter 3, and Chapter 11 on data analytics rewards a second reading.
• Selective: Chapters 15–21 are specialised allocation, process-costing and inventory topics to choose from as the course requires.
• For control courses: Chapters 23–24, ideally alongside a dedicated management control text.

Work the Try It! exercises as you read, and rebuild the budgets and variance analyses in a spreadsheet so that the formulas connect to the pricing, product-mix and control questions the chapters raise.
