Chapter 31: Cost & Management Accounting Overview

📚 JAIIB 2026 • AFM • Module D • Chapter 3 of 7 • Unit 31

An Overview of Cost & Management Accounting
(What Does It COST to Make a Product? And How Does Management USE That Info?)

Financial accounting tells you the TOTAL profit. Cost accounting tells you which PRODUCT made profit and which didn’t. Management accounting uses BOTH to help managers make better decisions. This chapter covers cost elements, 8 costing methods, 7 costing techniques, cost centres/units, CAS standards, and the key differences between all three types of accounting.

Banky Discovers: WHAT Does It COST? 🏭📊

A car factory makes 5 models. Total profit = ₹50 crore. But WHICH model made money and which LOST money? Financial accounting can’t tell you. COST accounting can! And management accounting helps the CEO decide: should we STOP making the losing model?

“Sir, when a borrower says his product costs ₹100 to make, how do I verify?” — “Ask for the COST SHEET! Materials + Labour + Overheads = Total Cost!” 📋

Cost & Management Accounting — Complete Overview

📖 Part 1 — Cost Elements + Fixed/Variable/Semi-Variable

Cost = expenditure incurred to produce a product or provide a service. Costing = ascertaining that cost.

3 Elements (by nature):

Materials: Direct (part of product — steel in car) vs Indirect (not part of product — lubricants, welding electrodes).

Labour: Direct (production workers — wages) vs Indirect (stores, admin, security staff).

Expenses: Direct (traceable to specific product — special design cost) vs Indirect (can’t allocate — rent, insurance, lighting).

By volume behaviour: Fixed = same regardless of production (insurance premium). Variable = directly proportional to production (engine cost per car). Semi-Variable = partly fixed, partly variable (admin staff — increases but not proportionally).

🧑‍💼 Banky: “Direct = you can TRACE it to a specific product (steel in a car). Indirect = you CAN’T trace it (factory rent — shared by all products!)” 🏭

📋 Part 2 — Cost Centre, Cost Unit + 8 Methods of Costing

Cost Centre: Smallest organisational unit for separate cost allocation. Example: brakes department in car factory. Types: Productive, Unproductive (support), Mixed. In a bank: cash department = one cost centre, loan department = another.

Cost Unit: Unit of product/service for which cost is calculated. Examples: Kilometre (transport), Kilogram (sugar), Barrel (oil), Kilowatt-hour (electricity), Litre (chemicals). Can be ANY physical measurement — number, weight, area, length, time.

8 Costing Methods: (1) Job = specific order (ship, mall). (2) Batch = group of similar items = one job. (3) Operation = cost of each operation in process. (4) Process = cost per process stage (oil refinery, chemicals). (5) Unit/Single-output = one product (bricks, cement, sugar). (6) Service = services not goods (electricity, hospital, transport). (7) Multiple/Composite = complex products with many components (aircraft, cars). (8) Departmental = cost per department.

🧑‍💼 Banky: “Job = custom order (one ship). Process = stages (oil refinery). Service = utilities (per kWh). Multiple = complex assembly (aircraft = many components!)” 🏗️

🏢 Part 3 — 7 Techniques + Management Accounting + CAS

7 Costing Techniques: (1) Historical = costs after production (past data, no control). (2) Standard = pre-set standard costs vs actual → variance analysis. (3) Marginal = extra cost of one more unit (fixed vs variable). (4) Uniform = same method across companies for comparison. (5) Direct = only direct costs allocated. (6) Absorption = ALL costs (direct + indirect) allocated. (7) ABC (Activity Based) = allocate overheads based on actual activity consumption.

Management Accounting: WIDER scope than cost accounting. Uses financial + cost + statistical data. Helps management in strategy, planning, control, decision-making, resource optimisation. Includes budgetary control, ratio analysis, cash/fund flow, break-even. Financial planning = a tool of management accounting (NOT financial accounting!).

Cost Accounting Standards (CAS): Issued by Institute of Cost Accountants of India (ICoAI) — NOT ICAI, NOT ISO, NOT MCA! 24 CAS issued so far.

Key differences: Financial accounting = statutory, external stakeholders, actual figures, quarterly/annually. Cost accounting = mostly voluntary, internal (management), includes estimates, can be daily. Management accounting = widest scope, futuristic, uses all tools.

🧑‍💼 Banky: “Financial = for outsiders. Cost = for product pricing. Management = for CEO’s decisions! CAS by ICoAI (not ICAI!). Financial planning = management accounting tool!” 📊

Exam-Ready Points

🎯 Must Remember!

  • Cost accounting evolved because: Financial accounting was NOT enough for complex business decisions (NOT because govt/shareholders demanded!).
  • Cost/Management accounting info used mainly by: MANAGERS (not investors, not bankers, not all stakeholders).
  • Cost unit can be: Kilometre, Kilolitre, Kilogram — ALL physical measurements. Answer = “All of the above.”
  • Financial planning = tool of MANAGEMENT accounting (NOT financial or cost accounting).
  • CAS issued by: Institute of Cost Accountants of India (ICoAI). NOT ICAI, NOT ISO, NOT MCA.
  • Direct cost = traceable to specific product. Indirect = cannot be directly allocated.
  • Fixed = same regardless of output. Variable = proportional. Semi-variable = partly both.
  • Cost centre types: Productive, Unproductive (support), Mixed.
  • Management accounting scope > Cost accounting scope > Financial accounting scope.
  • Cost accounting = mainly internal use. Financial accounting = external stakeholders.

Last-Minute Flash Cards

Cost vs Costing
Cost = expenditure to produce | Costing = finding that cost
Consumer’s cost = purchase price. Producer’s cost = production expenditure.
3 Elements
Materials | Labour | Expenses
Each split into Direct (traceable) and Indirect (not traceable).
Fixed Cost
Same regardless of production volume
Rent, insurance, salary of admin staff. Doesn’t change with output.
Variable Cost
Directly proportional to production
Raw materials, direct labour. Doubles if production doubles.
Semi-Variable
Partly fixed + partly variable
Increases with production but NOT proportionally. Admin dept expansion.
Cost Centre
Smallest unit for separate cost allocation
Productive, Unproductive, Mixed. Bank: cash dept = 1 centre, loans = another.
Cost Unit
Unit for which cost is calculated
KM (transport), KG (sugar), Barrel (oil), kWh (electricity). Any physical measure.
Job Costing
Specific order — ship, mall, garage repair
Custom work. Each job = unique costing exercise.
Process Costing
Cost per stage — refinery, chemicals, textiles
Output of one stage = input of next. Each stage costed separately.
Standard Costing
Pre-set standards vs actual = variance analysis
Identifies inefficiency. Controls costs. Future-oriented.
ABC (Activity Based)
Allocate overheads by actual activity consumption
More accurate than blanket allocation. Used for pricing, outsourcing decisions.
CAS
Cost Accounting Standards by ICoAI
24 standards issued. NOT by ICAI, ISO, or MCA!
Management Accounting
WIDEST scope | Uses all tools | Futuristic
Financial planning = its tool. Includes cost + financial + statistical techniques.
Who Uses What?
Financial = external | Cost = internal | Management = CEO
Financial = statutory. Cost = voluntary (mostly). Management = decision-making.

⚡ Module D • Chapter 3 (Unit 31) Done!

  • 3 Elements: Materials, Labour, Expenses — each Direct or Indirect. Fixed/Variable/Semi-variable.
  • Cost Centre: Smallest allocation unit (Productive/Unproductive/Mixed). Cost Unit: physical measure (KG/KM/KWh).
  • 8 Methods: Job, Batch, Operation, Process, Unit, Service, Multiple, Departmental.
  • 7 Techniques: Historical, Standard, Marginal, Uniform, Direct, Absorption, ABC.
  • CAS by ICoAI (24 standards). Financial planning = management accounting tool.
  • Scope: Management > Cost > Financial. Cost = internal use. Financial = external stakeholders.

Banky says: “Direct = traceable! Indirect = shared! Fixed = same! Variable = proportional! CAS by ICoAI! Management accounting = widest scope! 4 more chapters to go!” 🎉🏭📊
