Cost Accounting: Meaning, Objectives and Scope for CMA Inter

Updated 10 October 2026 · Fact-checked

Cost accounting is the process of recording, classifying, allocating and analysing costs so that the cost of products or services can be found, controlled and reported to management. Its main objectives are cost ascertainment, cost control, cost reduction, pricing support and decision-making. Learn the four terms (cost, costing, cost accounting, cost accountancy) and how they differ.

Understand Cost Accounting: Meaning, Objectives and Scope

Start with cost. Cost is the amount of resources given up to get something: a product, a service or an activity. It is measured in money. For example, the cost of a steel almirah is the money spent on steel, labour, paint, power and the factory that made it.

Costing is the technique of finding that cost. It uses principles and rules to work out the cost of a product, job, process or service. Costing can be done by simple arithmetic and need not be a full accounting system. Cost accounting goes further. It is the formal system of recording expenses, classifying them, allocating them to products or departments, and reporting them to management.

Cost accountancy is the widest term. It covers the application of costing and cost accounting principles, and also cost control, cost reduction, cost audit and the use of cost data in management decisions. A simple way to remember the order: cost is the amount, costing is the technique, cost accounting is the system, and cost accountancy is the whole profession and practice.

The objectives of cost accounting are: (1) ascertaining the cost of products and services; (2) controlling cost by comparing actual with standard or budget; (3) reducing cost without hurting quality; (4) fixing prices and quotations; (5) finding profit by product, job or department; (6) helping management plan, decide and measure performance; and (7) supplying data for cost statements and cost audit.

The scope is broad. It covers cost ascertainment, cost control, cost reduction, cost audit and cost reporting. It applies to manufacturing, and also to services such as transport, hospitals, hotels, power and banking, and to trading and government work. Management uses it for planning (budgets, standards), controlling (variance analysis), decision-making (make or buy, pricing, product mix) and performance evaluation.

Key rules to remember

Cost accounting in one line: Cost accounting = recording + classifying + allocating + reporting of costs; Use this to define the term in a sentence. Add 'for ascertainment and control' to earn full marks.
Hierarchy of terms: Cost → Costing → Cost accounting → Cost accountancy; Each term is wider than the one before. Cost is the amount; cost accountancy is the widest practice.
Core objectives: Ascertainment, control, reduction, pricing, decision support, reporting; List these in your answer. Give one line of explanation for each.
Cost control vs cost reduction: Control = keep to a target; Reduction = lower the target itself; Control compares actual with standard. Reduction is a real, permanent saving without loss of quality.

How to solve Cost Accounting: Meaning, Objectives and Scope questions

Theory questions on this topic reward a clear structure. Use the same frame for definitions, objectives, scope and management-role questions.

1Read the verb. 'Define', 'explain', 'distinguish' and 'discuss' need different depths.
2Open with a one-line definition of the term asked, in your own words.
3If the question names several terms, put them in a short list and define each in one line.
4List the points (objectives, scope or uses) as numbered headings, each with one sentence of explanation.
5Add a small example from a business, such as a Pune auto-parts maker or a Mumbai hospital, to show application.
6For 'distinguish' questions, write the difference in two columns or in pairs of lines on the same basis.
7Close with one line on how management uses the information, since the paper stresses its role in decisions.

Quickest way: Define, list, example

When to use it: Use this for a 14-mark theory question or a quick MCQ with limited time.

Write the definition in one or two lines.
List 5 to 7 points as short numbered lines.
Add one example line.
For MCQs, eliminate options that mix up costing with cost accountancy or call cost control the same as cost reduction.

Common mistakes in Cost Accounting: Meaning, Objectives and Scope

Treating costing, cost accounting and cost accountancy as the same thing
The names sound alike and many notes use them loosely.
Fix: Remember the order: technique, then system, then wide practice including control, reduction and audit. State the difference when the question asks for it.
Saying cost control and cost reduction mean the same
Both aim to lower expenditure.
Fix: Control keeps cost within a fixed target. Reduction lowers the target itself through better methods, without loss of quality.
Limiting cost accounting to factories
Most examples in the syllabus use manufacturing.
Fix: Mention services too, such as transport, hospitals, hotels and power, when you write about scope.
Writing objectives without explanation
Students memorise a list and stop.
Fix: Give a one-line meaning or example for each objective. Marks are given for explanation.
Ignoring the management role
Students focus on definitions only.
Fix: Add planning, control, decision-making and performance measurement, with an example such as a pricing or make-or-buy decision.

Worked examples

Example 1

Distinguish between costing and cost accountancy. (Short note, about 5 marks.)

Show the solution

Costing is the technique and process of ascertaining cost, using rules to work out the cost of a product, job or service.
Cost accountancy is wider. It includes cost accounting, cost control, cost reduction, cost audit and use of cost data for management decisions.
Basis of scope: costing is limited to ascertaining cost; cost accountancy covers ascertainment, control, reduction and audit.
Basis of nature: costing is a technique; cost accountancy is a practice or profession.
Basis of use: costing gives a cost figure; cost accountancy uses that figure to guide management action.
Example: working out that one steel almirah costs ₹4,800 is costing. Comparing actual with standard, finding why it exceeded ₹4,500 and acting on it is part of cost accountancy.

Answer: Costing is the technique of finding cost. Cost accountancy is the broader practice that covers ascertainment, control, reduction, audit and managerial use of cost data.

Example 2

Explain the objectives of cost accounting and how it helps management of a manufacturing company, Rao Engineering Ltd.

Show the solution

Define: cost accounting records, classifies, allocates and reports costs for ascertainment and control.
Objective 1, ascertainment: find the cost per unit of each product, such as a pump, so that price and profit can be judged.
Objective 2, control: compare actual with standard or budget. If actual material cost is ₹1,10,000 against a standard of ₹1,00,000, the ₹10,000 difference is investigated.
Objective 3, reduction: find better methods or less waste so that the cost is lowered permanently without hurting quality.
Objective 4, pricing: give cost data for quotations and for fixing selling price.
Objective 5, decisions: help with make-or-buy, product mix and shut-down questions.
Role in management: it supports planning through budgets and standards, control through variance reports, and performance review by product or department.

Answer: Cost accounting ascertains, controls and reduces cost, supports pricing and decisions, and gives management the data it needs for planning, control and performance review.

Exam tips

Section A MCQs on this topic usually test definitions and the difference between terms. There is no negative marking, so attempt all 15.
In written answers, number your points and give one line of explanation each. Examiners award marks per point.
For 'distinguish' questions, compare on stated bases such as scope, nature and use, rather than writing two paragraphs.
Add a short example from a business or service. It shows application and lifts a plain answer.
Do not spend more than the marks justify. A 5-mark note needs about 5 clear points.
