Corporate and Management Accounting
Core concepts
This domain blends financial accounting, cost accounting and management accounting. Expect preparation and interpretation of financial statements, ratio analysis, funds flow and cash flow, cost sheets, marginal costing, standard costing, variance analysis, budgeting, and decision-making tools such as break-even and relevant costing.
Know the accounting equation, double-entry mechanics, accrual versus cash concepts, and the treatment of depreciation and provisions. In cost accounting, distinguish fixed, variable and semi-variable costs; understand contribution, profit-volume ratio, margin of safety and operating leverage. In standard costing, compute material and labour variances and know which are favourable or adverse.
Traps
- Sign errors in variances; adverse means actual cost exceeds standard for a cost item.
- Mixing contribution with gross profit.
- Using absorption costing logic in a marginal costing decision.
- Forgetting that a ratio's interpretation depends on the industry benchmark.
- Ignoring non-cash items in cash flow classification.
Worked example
A product sells at 100 with variable cost 60, so contribution is 40 and the P/V ratio is 40 percent. Fixed costs are 8,000, so break-even sales equal 8,000 divided by 0.40, which is 20,000. If actual sales are 30,000, the margin of safety is 10,000, or 33.3 percent of sales. A 10 percent rise in sales raises profit by 10,000 times 0.40, that is 4,000, illustrating operating leverage.
Always state the formula before substituting numbers.
