Budgets, Budgetary Control, Zero Base Budgeting, and Fixed vs Flexible Budget

## Budgets and Budgetary Control

### Core Definitions

  • Budget: Quantitative expression of a plan for a defined future period (e.g., planned sales volume, planned cash flows).
  • Budgeting: The process of making budgets and using them for planning, coordination, and control.
  • Budgetary Control: Making budgets → continuously comparing actual results with budgets → placing responsibility for deviations.

### Essential Elements of a Budget

A good budget should be:

  • Flexible enough for revision as conditions change
  • Broken into functional budgets (production, purchase, wages, etc.)
  • Compared with actuals; variances analysed and corrective action taken
  • Linked to a reward system to motivate employees
  • Used to fix responsibility to specific management persons

### Budgetary Control System

Features of Budgetary Control:

1. Determines objectives to be achieved

2. Lists activities required to achieve those objectives

3. Plans in both physical (sales quantity) and monetary (sales value) terms

4. Compares actual performance with targets and finds discrepancies

5. Initiates corrective action

Advantages:

1. Efficiency — Directs business activities toward defined sales and production targets

2. Expenditure control — Controls costs at each department level (production cost budget, wages budget)

3. Deviation detection — Reveals gap between target and actual performance

4. Resource utilisation — Ensures optimal use of men, money, and materials

5. Standard Costing — Facilitates implementation of the standard costing system

6. Cost consciousness — Encourages a culture of cost control and cost reduction

Limitations:

1. Estimate-based — Becomes unreliable if future business conditions change significantly

2. Time-consuming — Top management must devote considerable time to budget implementation

3. Requires cooperation — Staff may resist because budgets directly identify responsible persons

4. Expensive — Needs proper organisational structure, significant time, and money

5. Not a substitute for management — Cannot replace managerial judgment and decision-making

6. Rigid document — Does not automatically account for changing internal or external factors

Steps in Implementing Budgetary Control:

1. Define objectives — Clearly specify items of revenue and expenditure to be achieved

2. Identify the key/limiting factor — Determine the binding constraint (e.g., sales capacity, material availability) before preparing budgets

3. Appoint a Budget Controller — A senior full-time executive responsible for coordinating the budgeting process

4. Prepare a Budget Manual — A document containing key information, responsibilities, and procedures

5. Fix the budget period — Should align with the business cycle

6. Use past statistics judiciously — Only when similar conditions are expected to repeat in the future

### Zero Base Budgeting (ZBB)

Definition: Budgets prepared without any reference to past budgets or actual figures — every rupee of expenditure must be justified from scratch, as if starting from zero.

Key Features:

1. Every budget item (old or new) is critically evaluated

2. Focus is on "why" money needs to be spent, not just "how much"

3. Limited resources are allocated in order of priority; corporate targets override individual department targets

Advantages of ZBB:

1. Allocates scarce resources in order of priority

2. Based on cost-benefit analysis — no arbitrary cuts or incremental increases

3. Links budget to corporate targets (not just departmental wishes)

4. Identifies and eliminates areas of wasteful expenditure

5. Implements Management by Objectives (MBO)

### Fixed vs Flexible Budget

Fixed Budget: Designed to remain unchanged regardless of the actual level of activity achieved. All costs are budgeted for one activity level only.

Flexible Budget: Designed to change in relation to the actual level of activity achieved, by recognising the behaviour of fixed, semi-variable, and variable costs.

Circumstances Where Flexible Budget is Needed:

1. Industries with seasonal fluctuations in sales/production (e.g., soft drinks, umbrellas)

2. Companies that frequently change product design (e.g., mobile phone manufacturers)

3. Made-to-order industries (e.g., ship building, construction)

4. Industries influenced by fashion changes

5. Labour-intensive industries where output varies with workforce changes

DimensionFixed BudgetFlexible Budget
Activity levelOne fixed levelMultiple activity levels
Cost behaviourAll costs treated uniformly at one levelEach cost classified by behaviour (F/V/SV)
Variance analysisNot useful (all costs at one level)Provides meaningful insight into each cost element
Comparison with actualMeaningless when actual activity ≠ budgeted activityAlways meaningful — comparison at actual activity level

Worked example

### Example 1

Fixed vs Flexible Budget — Why Fixed Budget Fails:

A factory budgets production of 1,000 units. Fixed budget: Variable costs ₹50,000; Fixed costs ₹30,000; Total ₹80,000.

Actual production = 800 units. Actual costs: Variable ₹40,000; Fixed ₹30,000; Total ₹70,000.

Fixed budget comparison: Actual ₹70,000 vs Budget ₹80,000 → shows ₹10,000 'saving' — MISLEADING because it ignores the lower output level.

Flexible budget at 800 units: Variable = (50,000/1,000)×800 = ₹40,000; Fixed = ₹30,000; Total = ₹70,000.

Flexible comparison: Actual ₹70,000 vs Flexible ₹70,000 → Zero variance — the true picture showing no inefficiency.

### Example 2

Zero Base Budgeting vs Traditional — Priority Allocation:

A company has ₹5 lakh available for departmental budgets. Departments submit requests: Marketing ₹3L, R&D ₹2L, Admin ₹2L, Training ₹1L.

Traditional approach: Last year's budget was Marketing ₹2.5L, R&D ₹1.5L, Admin ₹1L — each gets a 10% increase = ₹2.75L + ₹1.65L + ₹1.1L, total ≈ ₹5.5L (over budget, arbitrary cuts needed).

ZBB approach: Each dept justifies every rupee from scratch. After cost-benefit analysis, priority order: R&D ₹2L (new product pipeline), Marketing ₹2L (direct revenue link), Training ₹0.8L (productivity gain), Admin ₹0.2L (only essential activities). Total = ₹5L — aligned to corporate targets.

⚠️ Common exam mistakes

  • Confusing 'budgeting' with 'budgetary control' — budgeting is just the preparation of budgets; budgetary control also includes the ongoing comparison of actual vs budget and corrective action.
  • Thinking ZBB means 'zero expenditure' or 'starting with a zero budget amount' — it means starting WITHOUT REFERENCE TO PAST figures; all expenditure must be freshly justified.
  • In fixed vs flexible budget: comparing actual costs at 800 units against a fixed budget set at 1,000 units without adjusting — this variance is misleading and meaningless. Always use flexible budget for meaningful performance evaluation.
  • Forgetting that the KEY FACTOR (limiting factor) must be identified BEFORE preparing functional budgets — the budget of the key factor is prepared first, then all other budgets are built around it.
  • Listing 'not a substitute for management' as an advantage instead of a limitation — budgetary control supplements but cannot replace managerial judgment.
