Introduction to Management Accounting
Domain focus
Management accounting supplies internal information for planning, control and decision making. The CMA Inter paper tests whether you can distinguish it from financial accounting, identify cost objects and classify costs by behaviour, traceability and function, and carry those classifications into later calculations.
Core rules
- Financial accounting reports to external users under accounting standards; management accounting is internal, forward-looking and not governed by prescribed formats.
- A cost object is anything for which a separate cost is measured: product, department, customer or project.
- Direct costs can be traced economically to the object; indirect costs are allocated or apportioned.
- Product costs attach to inventory (direct material, direct labour, production overhead); period costs are expensed in the period.
- Behaviour classification: fixed, variable, semi-variable and stepped. The relevant range matters.
Worked example
A bakery makes 2,000 loaves a month. Flour at ₹15 per loaf is a direct variable product cost. Bakery rent of ₹40,000 a month is a fixed period cost unless absorbed into production. A supervisor paid ₹30,000 regardless of output is fixed production overhead. If the cost object changes from loaf to delivery route, flour is no longer direct. Reasoning: classify by traceability to the chosen object and by behaviour within the relevant range.
Traps
Calling every fixed cost a period cost; forgetting that directness depends on the cost object; treating sunk costs as relevant; confusing cost allocation with cost causality; assuming unit fixed cost is constant.
