Introduction to Management Accounting

  • Management accounting is internally focused, forward-looking and unregulated; financial accounting is externally focused, historical and governed by statute and accounting standards.

  • Cost object: anything for which a separate measurement of cost is required (product, department, customer, activity).

  • Direct cost is traceable to a cost object without apportionment; indirect cost (overhead) is not economically traceable and must be allocated or apportioned.

  • Prime cost = direct material + direct labour + direct expenses. Conversion cost = direct labour + production overhead.

  • Product cost is inventorised until sale; period cost is written off in the period incurred.

  • Cost classification bases: nature/element, function, behaviour (fixed, variable, semi-variable), traceability, controllability, relevance for decisions.

  • Value chain: R&D, design, production, marketing, distribution, customer service. Management accounting spans all links, not only production.

  • Line vs staff: line managers hold authority for operations; staff (management accountant) advises and supplies information without command authority.

  • Cost accounting is a subset of management accounting; it feeds cost data into planning, control and decision support.

Cost and Revenue Analysis (Cost Behaviour, CVP, Marginal Costing)

  • High-low method: variable cost per unit = (cost at high activity − cost at low activity) / (high activity − low activity); fixed cost = total cost − variable cost at either point.

  • Contribution per unit = selling price − variable cost per unit. C/S ratio = contribution / sales (per unit or in total).

  • Break-even units = fixed cost / contribution per unit; break-even revenue = fixed cost / C/S ratio.

  • Margin of safety = actual or budgeted sales − break-even sales (units or value). Margin of safety % = margin of safety / actual sales.

  • Target profit units = (fixed cost + target profit) / contribution per unit. For target profit after tax, divide by (1 − tax rate) first.

  • Operating gearing = contribution / profit. High gearing means profit is highly sensitive to sales volume changes.

  • In marginal costing, closing inventory is valued at variable cost only; fixed production overhead is charged in full to the period.

  • Profit difference between absorption and marginal costing = change in inventory units × fixed production overhead absorption rate per unit.

  • For multi-product break-even, rank products by contribution per unit of limiting factor; break-even is reached by cumulative contribution.

Standard Costing and Variance Analysis

  • Material price variance = (standard price − actual price) × actual quantity purchased or used.

  • Material usage variance = (standard quantity for actual output − actual quantity used) × standard price.

  • Labour rate variance = (standard rate − actual rate) × actual hours paid.

  • Labour efficiency variance = (standard hours for actual output − actual hours worked) × standard rate.

  • Overhead fixed expenditure variance = budgeted fixed overhead − actual fixed overhead; volume variance = absorbed − budgeted fixed overhead.

  • Variable overhead variances are calculated on the same quantity basis as material usage and labour efficiency.

  • Sales price variance = (actual price − standard price) × actual quantity sold; sales volume profit variance = (actual quantity − budget quantity) × standard profit per unit.

  • Operating profit variances reconcile budgeted profit to actual profit: standard profit on actual sales ± cost variances (adverse variances reduce profit).

  • Idle time variance = idle hours × standard rate, always adverse; it is separated from the efficiency variance.

Budgeting and Budgetary Control (Flexible and Zero-Based Budgets)

  • Fixed budget is set for one activity level; flexible budget is recast for the actual activity level so like-for-like comparison is possible.

  • Flexed budget = budgeted fixed cost + (actual units × budgeted variable cost per unit).

  • Incremental budgeting starts from last period's figures and adjusts; zero-based budgeting rebuilds each cost from a zero base and requires justification.

  • ZBB decision packages are ranked to allocate resources; it consumes more time and management effort than incremental budgeting.

  • Principal budget factor (limiting factor) is the constraint that governs the whole budget; the sales budget or production budget is prepared first accordingly.

  • Production budget (units) = sales units + closing finished goods − opening finished goods.

  • Material purchases (units) = production usage + closing inventory − opening inventory.

  • Cash budget records cash receipts and payments only; depreciation, accruals and bad debt write-offs are excluded from cash flow.

  • Rolling (continuous) budget is revised each period by adding a new period and dropping the expired one, keeping the horizon constant.

Activity Based Costing and Activity Based Management

  • ABC assigns overhead to cost pools by activity, then to products using cost drivers (machine hours, setups, orders, inspections, deliveries).

  • Cost driver rate = activity cost pool / total driver quantity. Overhead per product = sum of (driver quantity used × driver rate).

  • ABC is most useful where overhead is high, products are diverse, and batch or product-sustaining costs are significant.

  • ABC reduces cross-subsidisation caused by a single volume-based recovery rate, but is not a substitute for variable costing in short-term decisions.

  • Hierarchy of activities: unit-level, batch-level, product-sustaining, facility-sustaining. Facility-sustaining costs are not driven by products.

  • ABM uses ABC information to improve operations (activity analysis) and to change the mix of activities (business process re-engineering).

  • Value-added vs non-value-added activities: only non-value-added activities such as rework, storage and waiting are targets for elimination.

  • ABC cost data are more accurate for pricing and product-mix decisions but ignore unused capacity unless capacity-based drivers are used.

Decision Making: Relevant Costing

  • Relevant cost is a future incremental cash flow that differs between alternatives; past (sunk) costs and committed costs are irrelevant.

  • Opportunity cost is the contribution forgone from the next best alternative use of a scarce resource and is included in relevant cost.

  • For a special order, minimum price = incremental variable cost + any opportunity cost of capacity used.

  • Material already in stock: relevant cost is nil if no alternative use; replacement cost if it will be replaced; net realisable value if it would otherwise be sold.

  • Labour: relevant cost is the wage paid if the labour is hired specifically; if transferred from other work, relevant cost is the contribution forgone.

  • Make-or-buy: compare variable cost of making plus opportunity cost of facilities with the buy price; avoidable fixed costs are relevant.

  • Shut-down decision: continue if contribution from the segment exceeds avoidable fixed costs.

  • With one limiting factor, rank products by contribution per unit of the scarce resource and produce in rank order.

  • With two or more limiting factors, use linear programming; the optimal solution lies at a corner of the feasible region.

Pricing Decisions and Short-term Decisions

  • Price elasticity of demand = % change in quantity demanded / % change in price. Demand is elastic where |e| > 1.

  • Profit-maximising price: marginal revenue = marginal cost. For P = a − bQ, MR = a − 2bQ.

  • Cost-plus pricing: price = cost × (1 + mark-up %). Full cost plus uses absorption cost; marginal cost plus uses variable cost and contribution.

  • Mark-up on cost vs margin on price: margin = mark-up / (1 + mark-up).

  • Target costing: target cost = competitive selling price − required profit margin; the cost gap must be closed by design and process improvement.

  • Penetration pricing sets a low initial price to build volume; price skimming sets a high initial price to capture early adopters.

  • Relevant (incremental) pricing for a one-off order is acceptable when spare capacity exists and the order does not cannibalise existing sales at a lower price.

  • Transfer price minimum for the selling division = variable cost + opportunity cost of the transferred unit.

Investment Appraisal and Capital Budgeting

  • Payback period = time to recover the initial outlay from cumulative net cash inflows; it ignores cash flows after payback and the time value of money.

  • ARR = average annual accounting profit / average investment, where average investment = (initial cost + scrap value) / 2.

  • NPV discounts all relevant cash flows at the cost of capital; accept if NPV > 0. It is the preferred method because it is absolute and additive.

  • IRR is the discount rate at which NPV = 0; accept if IRR > cost of capital.

  • Annuity factor and discount factor tables: DF = 1/(1+r)^n; annuity factor is the sum of discount factors for the period.

  • Tax and depreciation: capital allowances give tax relief; depreciation itself is not a cash flow. Tax is normally assumed paid one year in arrears.

  • Relevant cash flows are incremental, after tax, and exclude sunk costs, allocated fixed overhead and financing costs already in the discount rate.

  • Capital rationing with divisible projects: rank by profitability index = NPV / initial investment; with indivisible projects, use trial combinations.

Performance Measurement and Divisional Transfer Pricing

  • ROI = divisional profit / divisional investment. RI = divisional profit − (imputed interest rate × divisional investment).

  • ROI can cause goal congruence problems because a manager may reject a project earning above the cost of capital but below the current divisional ROI.

  • RI encourages acceptance of any project earning above the imputed charge, but it is an absolute measure that is harder to compare across divisions.

  • Transfer price range: minimum = variable cost + opportunity cost of the selling division; maximum = lower of external market price and the buying division's net marginal revenue.

  • Market-based transfer price is appropriate where a competitive external market exists; cost-based transfer price is used where no market exists.

  • Dual transfer pricing credits the seller at market price and charges the buyer at variable cost; the difference is a head-office adjustment.

  • Balanced Scorecard perspectives: financial, customer, internal business process, learning and growth.

  • Non-financial indicators: quality, cycle time, on-time delivery, customer satisfaction, staff turnover, capacity utilisation.

  • Controllable profit excludes items not influenced by the divisional manager, such as apportioned head-office costs and interest.

  • Target profit units = (fixed cost + target profit) / contribution per unit. For target profit after tax, divide by (1 − tax rate) first.

  • Operating gearing = contribution / profit. High gearing means profit is highly sensitive to sales volume changes.

  • In marginal costing, closing inventory is valued at variable cost only; fixed production overhead is charged in full to the period.

  • Profit difference between absorption and marginal costing = change in inventory units × fixed production overhead absorption rate per unit.

  • For multi-product break-even, rank products by contribution per unit of limiting factor; break-even is reached by cumulative contribution.

  • Operating profit variances reconcile budgeted profit to actual profit: standard profit on actual sales ± cost variances (adverse variances reduce profit).
