SQA National 5 Accounting: Management Accounting - cost classification, costing, break-even, cash budgets and decision-making

What the Management Accounting area demands

Management Accounting is the second area of National 5 Accounting. Where Financial Accounting reports the past to outsiders, Management Accounting produces internal information so managers can plan, control costs and make decisions. The examiners reward accurate cost calculations, correct use of contribution, clear statements and budgets, and sensible recommendations. This guide ties the topic pages together; each has its own worked examples and practice questions.

Cost classification

The area opens by classifying costs. By behaviour: fixed costs stay the same as output changes (rent); variable costs change in proportion (raw materials); semi-variable costs have both parts. By traceability: direct costs trace to one product (direct materials and labour, together the prime cost); indirect costs (overheads) are shared. Every cost is also one of three elements: materials, labour or overheads. From these, total cost $=$ total variable $+$ total fixed cost, and cost per unit $=$ total cost $\div$ units.

Costing materials, labour and overheads

Next, the three elements are costed and built into a cost statement. Materials cost is the value of materials used; labour cost is hours times rate, with overtime paid at a premium such as time-and-a-half; overheads are absorbed across output, for instance as a percentage of direct labour cost. The statement shows prime cost (direct costs) and then total cost (prime cost plus overheads).

Break-even analysis

The heart of the area is break-even analysis, built on contribution $=$ selling price $-$ variable cost per unit. The break-even point in units $=$ fixed costs $\div$ contribution per unit; in revenue it is the break-even units times the selling price. The margin of safety shows how far sales exceed break-even, and units for a target profit $=$ (fixed costs $+$ target profit) $\div$ contribution. A break-even chart plots cost and revenue against output, crossing at break-even.

Cash budgeting

A cash budget forecasts liquidity month by month: net cash flow $=$ receipts $-$ payments, closing balance $=$ opening balance $+$ net cash flow, and each closing balance carries forward as the next opening balance. It records cash, not profit, excludes depreciation, and warns of shortfalls so the business can arrange an overdraft or delay payments in advance.

Decision-making and spreadsheets

Finally, managers decide using this information. For a special order with spare capacity and fixed costs already covered, accept it when the price beats the variable cost, because the contribution is extra profit. Spreadsheets prepare all this faster and more accurately - formulae recalculate automatically, "what if" changes update instantly, presentation is clear, and files are saved and reused.
