ACCT2002 Chap.1 Management Accounting and Cost Terms
Management Accounting and Cost Terms
Management accounting is information for planning, control and decision making inside an organisation. It is shaped by the decision rather than by a single external reporting format: the same resource can be classified by traceability, behaviour, inventory treatment or relevance, and each classification answers a different question. This chapter builds the vocabulary that prevents later formulas from becoming mechanical.
Start with the cost object, identify which costs can be traced economically, separate variable and fixed behaviour over a relevant range, and distinguish inventoriable product cost from period cost. Then connect the analysis to the value chain, ethical judgement and the five-step decision process described in the course recap.
The recurring warning is that a unit cost is an average, not a promise about what cost will change if one more unit is made.

Ethical judgement and the management accountant
Classify one cost four ways
- 3Timber is direct to the desk, variable with desks produced, and inventoriable because it becomes part of work in process and finished goods before sale.
- 2Factory rent is indirect to one desk, fixed within the current capacity range, and inventoriable manufacturing overhead allocated to production.
- 2Delivery cost is indirect to production of a desk, variable with deliveries rather than desks, and a period distribution cost rather than product cost.
- 2Advertising is indirect, fixed under the monthly commitment, and a period cost expensed as incurred.
- 1Traceability depends on the cost object. Factory rent is indirect to a desk but direct to the factory if the factory itself is the object being costed.
Key terms
- Management accounting
- The process of measuring, analysing and reporting financial and non-financial information that helps managers make decisions.
- Cost object
- Anything for which a separate cost measurement is desired.
- Direct cost
- A cost that can be traced to a cost object economically.
- Indirect cost
- A cost related to a cost object but not traced economically, so it is allocated.
- Relevant range
- The activity band over which an assumed cost-behaviour relationship is expected to hold.
- Inventoriable cost
- A product cost recorded as an asset until the related inventory is sold.
- Period cost
- A cost expensed in the period in which it is incurred because it is not inventoriable.
Management Accounting and Cost Terms FAQ
Is every direct cost variable?
No. Directness asks whether a cost can be traced to the selected object; variability asks whether total cost changes with an activity driver. A dedicated supervisor salary can be direct to a department and fixed within the relevant range.
Why can unit cost mislead?
A unit cost often allocates fixed cost across current output. Producing one more unit may change only variable cost if capacity is available, while cutting output does not automatically remove committed fixed cost. Use totals and identify which resources actually change.
What should I say in a classification answer?
Name the cost object, the driver and the time horizon. Then justify each label in one sentence rather than listing labels without reasoning.
How does this chapter connect to assessment?
The cost vocabulary supports later costing, CVP, budgeting, variance and relevant-information questions. Practise explaining the classification choice as well as calculating an amount.
Exam move
Build a classification matrix from ordinary business costs. For each item, change the cost object and ask whether the label changes. Then change the time horizon and activity range. Finish every exercise by writing the decision consequence: whether the classification affects inventory profit, cost prediction or a relevant-cost comparison.
In workshop practice, attempt the sub-questions before consulting the released answer and work backwards through any classification that differs. For viva preparation, explain in sixty seconds why “direct”, “variable” and “product” are not synonyms.
