Principles of Costing — overview
This unit gives students an introduction to the principles of basic costing and builds a solid foundation in the knowledge and skills required for more complex costing and management accounting. Students will learn the importance of the costing system as a source of information that allows management to plan, make decisions and control costs. Students should recognise the key differences from a business perspective between costing and financial accounting.
Students will learn a range of techniques to cost materials, labour and overheads to establish the unit cost of a product or service, and this will include understanding and applying codes. Students will learn how to classify costs and will understand how different classifications of cost can be used for internal management decision making.
Students will understand how cost behaves at different levels of output, and how variable and fixed costs per unit behave as output changes. Students will learn to build a basic unit product cost using labour hours, machine hours and per unit as a basis. This will prepare students and give them the basic tools for studies in overhead apportionment, reapportionment and absorption in later units. They will learn that overhead is a large, and in many cases the largest, component of cost. The budgetary control system is introduced, and by comparing actual costs with budgeted costs for a single product and using a fixed budget, students will determine variances, noting whether they are adverse or favourable and reporting to management on their causes and effects.
What You'll Learn
- Understand the cost recording system within an organisation
- Use cost recording techniques
- Provide information on actual and budgeted costs and income

How to pass Principles of Costing
Expert tips from Learnsignal's AAT tutors to help you prepare effectively.
Nail the cost classifications first
Direct vs indirect, fixed vs variable, product vs period — every question depends on you classifying costs correctly. Learn definitions cold before you attempt any calculations.
Practise the inventory valuation methods
FIFO, AVCO, and (less often) LIFO are tested on numerical questions. Work through the same stock card in all three methods until you can reconcile the differences in cost of sales and closing stock.
Get comfortable with labour cost calculations
Basic, overtime, bonus, and piece-rate calculations come up repeatedly. Know how to calculate gross pay under each method and how to allocate between direct and indirect labour.
Understand budget vs actual comparisons
You'll be asked to calculate simple variances and comment on whether they're favourable or adverse. Practise the comparison format AAT uses in sample assessments.
Cost-behaviour questions test understanding, not just maths
Expect short-answer questions about why a cost behaves a certain way. Link back to whether it's fixed, variable, stepped, or semi-variable and explain clearly.
Review your arithmetic
At 70% pass mark, a handful of arithmetic slips can cost you the exam. Leave 10 minutes at the end to re-check numbers — especially any figure you had to round.
