Purposes of Budgeting

A budget is a quantitative plan for a defined future period, expressed in financial and/or physical terms. Budgets serve seven key purposes:

  1. Planning: Forces management to think ahead, set objectives, anticipate problems, and develop strategies. Translates strategic plans into operational detail.
  2. Coordination: Ensures all departments work towards common goals. The production budget is coordinated with sales, purchasing with production, and so on.
  3. Communication: Communicates plans, targets, and expectations throughout the organisation. Ensures everyone understands what is expected.
  4. Control: Provides a benchmark against which actual performance is compared. Variances trigger investigation and corrective action (management by exception).
  5. Motivation: Well-set targets can motivate staff to achieve. Budgets give employees clear goals and a sense of direction. However, poorly set targets can demotivate (see behavioural aspects).
  6. Performance evaluation: Managers are assessed against their budgeted targets. Budgets form the basis for performance appraisal and reward systems.
  7. Resource allocation: Helps allocate scarce resources (cash, labour, materials, capacity) to competing priorities based on planned activities.

Budget Preparation Process

The budget is typically prepared annually, starting several months before the budget period. The process is coordinated by a budget committee (usually chaired by a senior finance executive) with a budget manual providing guidance on procedures, timetables, and responsibilities.

The principal budget factor (limiting factor):

The budget preparation begins by identifying the principal budget factor — the factor that limits the organisation's activities. Usually this is sales demand (the maximum the market will buy), but it could also be: production capacity, availability of raw materials, availability of skilled labour, or cash/financing. The budget for the limiting factor is prepared first, and all other budgets flow from it.

Sequence of budget preparation (when sales is the limiting factor):

  1. Sales budget (units and revenue) — prepared first as it drives everything else
  2. Production budget (units to produce = sales + desired closing inventory − opening inventory)
  3. Materials purchases budget (materials needed for production + desired closing materials inventory − opening materials inventory)
  4. Direct labour budget (labour hours and cost needed for production)
  5. Production overhead budget (variable and fixed overheads for the production level)
  6. Selling and administrative overhead budget
  7. Capital expenditure budget
  8. Cash budget (timing of all cash receipts and payments)
  9. Master budget — budgeted SoPL and budgeted SoFP

Functional Budgets

Functional budgets are the detailed budgets for each area of the business. The key ones are:

Sales budget:

Sales revenue = Budgeted sales units × Selling price per unit

May be broken down by product, region, customer, or sales channel.

Production budget (units):

Production = Budgeted sales + Required closing finished goods inventory − Opening finished goods inventory

The closing inventory level is a management decision based on desired buffer stock, lead times, and demand uncertainty.

Materials purchases budget:

Materials required for production = Production units × Materials per unit

Materials to purchase = Materials required + Required closing raw materials inventory − Opening raw materials inventory

Materials cost = Materials to purchase × Price per unit of material

Direct labour budget:

Labour hours required = Production units × Labour hours per unit

Labour cost = Labour hours × Hourly rate

Consider overtime if hours exceed normal capacity. May need to plan recruitment or training.

Production overhead budget:

Variable production OH = Production units × Variable OH per unit

Fixed production OH = Budgeted fixed amount (does not change with volume within the relevant range)

Cash Budget

The cash budget shows the timing of cash receipts and payments, typically on a monthly basis. It is crucial for ensuring the business has sufficient cash to meet its obligations and for planning any financing needs.

Cash budget format:

Month 1 £Month 2 £Month 3 £
Receipts
Cash from customersXXX
Other receipts (loans, asset sales, etc.)XXX
Total receiptsXXX
Payments
Payments to suppliers(X)(X)(X)
Wages and salaries(X)(X)(X)
Overheads (cash items only — exclude depreciation)(X)(X)(X)
Capital expenditure(X)(X)(X)
Tax, dividends, loan repayments(X)(X)(X)
Total payments(X)(X)(X)
Net cash flowX/(X)X/(X)X/(X)
Opening cash balanceXXX
Closing cash balanceXXX

Key differences between the cash budget and the budgeted profit statement:

  • Timing: Revenue is recognised when earned (accruals basis) but cash is received when customers pay (which may be 30, 60, or 90 days later). Similarly, costs are recognised when incurred, but cash is paid when the bill is settled.
  • Depreciation: Charged as an expense in the profit statement but is NOT a cash payment — excluded from the cash budget.
  • Capital expenditure: The purchase of a non-current asset is a cash payment (in the cash budget) but only depreciation is charged as an expense (in the profit statement).
  • Receivables and payables: Credit sales create receivables (profit recognised now, cash later); credit purchases create payables (cost recognised now, cash later).
  • Loans and share issues: Cash receipts from financing (in the cash budget) are not revenue (not in the profit statement).
  • Inventory changes: Affect cost of sales in the profit statement but cash is spent when materials are purchased (which may differ from the period of use).

Master Budget

The master budget consolidates all functional budgets into two summary financial statements:

1. Budgeted statement of profit or loss (budgeted income statement):

£
Revenue (from sales budget)X
Less: Cost of sales
   Opening inventory (FG)X
   + Production cost (materials + labour + overheads)X
   − Closing inventory (FG)(X)
= Cost of sales(X)
Gross profitX
Less: Selling and admin overheads(X)
Budgeted net profitX

2. Budgeted statement of financial position:

Shows the expected financial position at the end of the budget period. Non-current assets (including budgeted capex less depreciation), current assets (closing inventory of raw materials and finished goods, trade receivables, cash from the cash budget), equity (opening equity + budgeted profit − dividends), and liabilities (trade payables, loans, tax).

Flexed Budgets

A flexed budget adjusts the original (fixed) budget to the actual level of activity. It shows what costs and revenues should have been at the actual volume, enabling meaningful comparison with actual results.

Why flex the budget?

Comparing actual results to the original (fixed) budget is misleading when actual activity differs from budget — differences are caused by both volume changes and price/efficiency changes. Flexing separates these effects:

  • Original budget vs Flexed budget = Volume variance (the effect of producing/selling more or fewer units than planned)
  • Flexed budget vs Actual = Expenditure/efficiency variances (the effect of prices and efficiency being different from standard)

How to flex:

  • Variable costs: Scale in proportion to actual activity. Flexed variable cost = Standard variable cost per unit × Actual units.
  • Fixed costs: Remain at the original budgeted amount (they do not change with activity).
  • Semi-variable costs: The variable element flexes; the fixed element stays the same.
  • Revenue: Flex to actual volume at the standard selling price per unit.

Example structure:

Original budget
(1,000 units)
Flexed budget
(1,100 units)
Actual
(1,100 units)
Flexed variance
Revenue50,00055,00054,0001,000 A
Variable costs(30,000)(33,000)(34,500)1,500 A
Contribution20,00022,00019,5002,500 A
Fixed costs(10,000)(10,000)(10,800)800 A
Profit10,00012,0008,7003,300 A

Volume variance = Flexed profit (12,000) − Original profit (10,000) = £2,000 F (sold more units).
Flexed variances = Actual profit (8,700) − Flexed profit (12,000) = £3,300 A (prices/efficiency worse than standard).

Budgeting Approaches

ApproachMethodAdvantagesDisadvantages
Incremental Start with the previous period's budget/actuals and make adjustments for expected changes (inflation, volume, known cost changes). Simple, quick, stable, low cost, easy to understand Perpetuates past inefficiencies, does not encourage critical review, may lead to budget padding/slack, unsuitable for rapidly changing environments
Zero-based (ZBB) Start from zero each period. Every activity must be justified from scratch — no automatic carry-forward. Activities are ranked in "decision packages" by priority. Eliminates historical inefficiency, forces critical evaluation, focuses resources on priorities, identifies low-value activities Very time-consuming, resource-intensive, potentially demoralising, difficult to rank dissimilar activities, may lead to short-termism
Rolling (continuous) Budget is continuously updated — as one period expires, a new period is added. Always covers a fixed number of periods ahead (e.g., always 12 months). Always current, forces regular planning, reduces year-end gaming, more realistic targets Time-consuming (continuous preparation), targets keep changing (can create uncertainty), requires disciplined process
Activity-based (ABB) Budgets are built by estimating the cost and volume of activities required to meet budgeted output, using ABC cost drivers. Reverses the traditional approach — works from planned output back to required activities and resources. More accurate budgets (reflects actual resource consumption), encourages understanding of cost drivers, supports cost management Complex, requires established ABC system, data-intensive, may be impractical for simple operations

Beyond Budgeting

Beyond budgeting is a management philosophy that advocates abandoning the traditional annual budget entirely, replacing it with a more adaptive, decentralised management model.

Criticisms of traditional budgeting that beyond budgeting addresses:

  • Traditional budgets are time-consuming and expensive to prepare
  • They are based on assumptions that quickly become outdated in a fast-changing environment
  • They encourage gaming and dysfunctional behaviour (padding, spending up to budget, sandbagging targets)
  • They create rigid, centralised control that stifles innovation and responsiveness
  • They focus on fixed targets rather than relative performance and continuous improvement
  • They lead to an annual cycle mentality ("spend it or lose it" near year end)

Beyond budgeting principles:

  • Replace fixed annual targets with relative targets (benchmarked against competitors or internal best practice)
  • Use rolling forecasts instead of fixed budgets — continuously updated, looking forward
  • Decentralise decision-making — empower front-line managers to act quickly without waiting for budget approval
  • Reward performance relative to peers and external benchmarks, not against a fixed budget
  • Allocate resources dynamically based on current needs, not annual allocations
  • Foster a culture of continuous improvement rather than "meeting the budget"

Limitations: Requires a significant cultural shift, may be difficult to implement in large bureaucratic organisations, regulatory and governance requirements may demand formal budgets (e.g., companies may need to provide market guidance based on budgets), and some managers may feel uncomfortable without fixed targets.

Behavioural Aspects of Budgeting

Budgets do not operate in a vacuum — they affect and are affected by human behaviour. Understanding behavioural dynamics is essential for effective budgeting.

Participation (top-down vs bottom-up):

  • Top-down (imposed) budgets: Set by senior management and imposed on lower-level managers. Advantages: quick, ensures strategic alignment, prevents padding. Disadvantages: may be unrealistic (lack local knowledge), demotivating (no ownership), may face resistance.
  • Bottom-up (participative) budgets: Prepared by the managers who will be responsible for achieving them, then aggregated and reviewed by senior management. Advantages: more realistic (uses local knowledge), motivating (ownership and commitment), better information. Disadvantages: time-consuming, may lead to budget slack (see below), may lack strategic coherence.
  • Negotiated budgets: A compromise — targets are discussed and agreed between senior and operational management. Generally considered the most effective approach.

Budget slack (padding):

Budget slack occurs when managers deliberately understate revenue or overstate costs in their budgets to make targets easier to achieve. Motivations: to ensure they "hit budget" and earn bonuses, to create a safety margin against uncertainty. Consequences: resources are misallocated, performance is not stretching, the budget fails as a planning tool. Controls: senior review, use of benchmarks, linking rewards to efficiency improvements rather than just meeting budget.

Motivation and target difficulty:

  • Targets set too easily do not motivate — there is no challenge. Performance will be mediocre.
  • Targets set too aggressively (unrealistic) are demotivating — managers give up because they believe the target is unachievable.
  • The ideal budget target is challenging but achievable — stretching enough to motivate effort, but realistic enough that managers believe they can succeed. Research suggests budgets should be achievable about 70-80% of the time for optimal motivation.

Dysfunctional behaviour:

  • Short-termism: Managers cut discretionary spending (training, maintenance, R&D) to meet short-term budget targets, damaging long-term performance.
  • Gaming: Manipulating the timing of revenues and costs to hit budget — e.g., delaying an order to next period, or pulling forward revenue.
  • Spend it or lose it: Managers spend remaining budget near year end to avoid having their budget reduced next year — wasteful expenditure.
  • Interdepartmental conflict: Budgets can create competition rather than cooperation between departments, especially when resources are scarce.

Examiner Focus

Functional budget preparation is heavily tested — especially the production budget (sales + closing inventory − opening inventory) and the materials purchases budget (production needs + closing RM − opening RM). These two formulas must be memorised cold.

Common Pitfall

In the cash budget, EXCLUDE depreciation — it is a non-cash charge. Include the FULL cost of capital expenditure (cash payment), but only depreciation appears in the profit statement. This is the most common error in cash budget questions.

Study Tip

For cash receipts from credit customers, draw a timeline: if terms are 60% in month of sale and 40% next month, Month 2 receipts = 60% of Month 2 sales + 40% of Month 1 sales. Don't forget to collect opening receivables in Month 1.

Examiner Focus

Know the comparison of budgeting approaches: incremental (simple, perpetuates waste), ZBB (thorough, time-consuming), rolling (always current, continuous effort), ABB (accurate, complex). The examiner often asks you to recommend an approach for a specific scenario — justify your recommendation.

Watch Out

Flexed budgets: variable costs flex, fixed costs DON'T. The flexed budget uses STANDARD prices/costs at the ACTUAL volume. Compare Original → Flexed = volume variance. Compare Flexed → Actual = expenditure/efficiency variances.

Common Pitfall

Behavioural aspects are often examined discursively. Know: participation (top-down vs bottom-up vs negotiated), budget slack (causes, consequences, controls), motivation (challenging but achievable = optimal), and dysfunctional behaviour (short-termism, gaming, spend-it-or-lose-it).

Key Definitions

Budget

A quantitative plan for a defined future period, expressed in financial and/or physical terms. Serves planning, coordination, control, communication, motivation, evaluation, and resource allocation purposes.

Principal budget factor (limiting factor)

The factor that constrains the organisation's activities — usually sales demand. The budget for this factor is prepared first, and all other budgets flow from it.

Functional budget

A detailed budget for a specific function or department — e.g., sales budget, production budget, materials purchases budget, labour budget, overhead budget.

Master budget

The consolidation of all functional budgets into a budgeted statement of profit or loss and a budgeted statement of financial position.

Cash budget

A budget showing the timing of cash receipts and payments, usually monthly. Used to ensure sufficient liquidity and plan financing. Excludes non-cash items like depreciation.

Flexed budget

The original budget adjusted to the actual level of activity. Variable costs flex; fixed costs remain unchanged. Enables meaningful variance analysis by comparing like-with-like.

Incremental budgeting

Starting from the prior period's budget/actuals and adjusting for expected changes. Simple but perpetuates past inefficiency and does not encourage critical review.

Zero-based budgeting (ZBB)

Every activity is justified from scratch each period — no automatic carry-forward. Eliminates inefficiency but is time-consuming and resource-intensive.

Rolling (continuous) budget

Continuously updated by adding a new period as the current one expires. Always covers a fixed number of periods ahead. More current but requires continuous preparation effort.

Activity-based budgeting (ABB)

Budgets built from estimated activity volumes and ABC cost driver rates. More accurate but requires an established ABC system.

Beyond budgeting

A management philosophy that replaces fixed annual budgets with rolling forecasts, relative targets, decentralised decision-making, and dynamic resource allocation.

Budget slack (padding)

Deliberately understating revenue or overstating costs to make budget targets easier to achieve. Undermines planning accuracy and resource allocation.

Participative (bottom-up) budget

Prepared by the managers responsible for achieving the targets, then reviewed by senior management. Increases ownership and realism but may introduce slack.

Key Formulas

Worked Examples

Key Takeaways

  • Budgets serve seven purposes: planning, coordination, communication, control, motivation, performance evaluation, and resource allocation.
  • The budget preparation process starts with the principal budget factor (usually sales). Sequence: sales → production → materials purchases → labour → overheads → capital expenditure → cash budget → master budget.
  • Production budget: Sales + Closing FG inventory − Opening FG inventory. Materials purchases: Production needs + Closing RM inventory − Opening RM inventory.
  • Cash budget shows timing of cash flows (monthly). Excludes depreciation (non-cash). Includes capital expenditure (cash). Differences from profit: timing (receivables/payables), depreciation, capital items, financing.
  • Master budget = budgeted SoPL + budgeted SoFP. Consolidates all functional budgets into summary financial statements.
  • Flexed budgets adjust the original budget to actual volume: variable costs flex proportionally, fixed costs stay the same. Enables meaningful variance analysis (volume variance vs expenditure/efficiency variances).
  • Budgeting approaches: incremental (simple, perpetuates waste), ZBB (justify from scratch — thorough but costly), rolling (continuously updated), ABB (uses ABC drivers — accurate but complex).
  • Beyond budgeting replaces fixed annual budgets with rolling forecasts, relative targets, and decentralised decision-making. Addresses gaming, rigidity, and short-termism.
  • Behavioural aspects: participative budgets increase ownership but may introduce slack. Optimal targets are challenging but achievable (~70-80% attainable). Dysfunctional behaviour: short-termism, gaming, spend-it-or-lose-it.
