A budget is where strategy meets the calendar. A board may decide to double the size of the business in five years, but nothing happens until someone says how many units will be sold next year, who will make them, what they will cost and when the cash will come in and go out.
The budget is that statement, written down in naira and agreed by the people who must carry it out.
This topic covers the planning framework in which budgets sit, what a budget is, the reasons a budgeting system matters, the people and documents involved in preparing a budget (the budget committee, the budget officer and the budget manual), the principal budget factor, and the eight stages of the budget process.
It also adds three short background notes that are tested in examinations: fixed and flexible budgets, types of budgeting, and the human aspects of budgeting. The next two topics prepare the functional budgets, the cash budget and the master budget.
In 30 seconds
A budget is a formal financial plan covering all activities of an organisation for a period, usually a year, divided into control periods such as months. Plans exist at three levels: long-term (strategic, 3 to 5 years or more), medium-term (tactical, 1 to 2 years, where budgets sit) and short-term (operational, weeks or months).
A budgeting system converts long-term plans into annual actions, coordinates departments (goal congruence), communicates plans, motivates, authorises spending, fixes responsibility, provides a benchmark for control and allocates resources. The budget committee supervises; the budget officer coordinates; the budget manual sets the rules. The principal budget factor (usually sales demand) limits activity, so its budget is prepared first. The process has eight stages, from identifying the factor to variance analysis.
The planning framework
An organisation plans over three time horizons, each with its own purpose.
| Level | Also called | Period | Focus | Example |
|---|---|---|---|---|
| Long-term | Strategic planning | 3 to 5 years or longer | The mission and long-term objectives. Sets the vision, core activities and major initiatives. Considers outside factors such as market trends, competition and economic conditions | Entering a new country within five years |
| Medium-term | Tactical planning | 1 to 2 years | How the strategy will be carried out. Identifies actions, resource needs and key performance indicators. Bridges strategy and daily operations | The annual budget |
| Short-term | Operational planning | Weeks or months | Immediate, day-to-day activities needed to keep the business running | Weekly production schedules, daily sales targets, staff rosters |
Budgets are medium-term plans expressed in financial terms. A typical budget is prepared for a year, and the overall budget is divided into control periods so that performance can be reported against it as the year goes on.
The nature of a budget
A budget is a formal, financial plan covering all of an organisation’s activities for a specific period, typically one year. It sets out expected revenues, expenses and the allocation of resources, to guide decisions and performance. The overall period can be broken into shorter control periods, such as months or quarters, so that results can be tracked and plans adjusted.
Budgets are used to predict financial outcomes, manage resources and monitor performance against goals.
Budgeting does more than produce a set of numbers. It aligns resources with business goals, encourages forward thinking, prompts managers to examine how operations work, and fosters coordination between departments. It supports control, because comparing actual results with the budget (variance analysis) reveals deviations and inefficiencies and allows prompt corrective action. It also builds a culture of financial discipline and continuous improvement.
Importance of the budgeting system
| Purpose | What it means in practice |
|---|---|
| Converting long-term plans into short-term actions | Breaks a strategic plan into detailed, actionable annual plans so that daily activity moves towards the long-term goals |
| Linking planning to strategy | Keeps short-term plans consistent with the long-term objectives of the organisation |
| Coordination (goal congruence) | Brings the actions of departments together so that all work towards the same goals. Production should not plan to make what sales cannot sell |
| Communication | Tells managers and staff what is planned and what is expected of them, so they understand their roles and targets |
| Motivation | Sets clear targets. Managers may earn bonuses or other rewards for meeting them |
| Authorisation of expenditure | Spending is approved if it falls within budgeted amounts, which promotes discipline |
| Definition of responsibility | Names the people responsible for each target, which reinforces accountability |
| Benchmark for evaluation | Actual results are compared with the budget. Variances are identified and corrective action taken |
| Resource allocation | Directs funds to priority areas and prevents overspending |
| Cost control and efficiency | Spending limits and tracking reveal waste and inefficiency |
| Strategic decision making | Provides financial data for decisions such as launching a product or entering a market |
Preparing the budget
In medium and large companies, preparing the annual budget is a major activity with a well-defined process, because many people must coordinate their efforts. It can take several months, from the start to the board’s approval.
The budget committee
The process is usually supervised by a budget committee of senior managers from the main areas of the business. The committee reviews the functional budgets submitted to it, checks that they are consistent with each other, and instructs changes where drafts are unsatisfactory. Although the committee manages the process, each functional budget is normally prepared by the manager responsible for that area.
A sales manager prepares the sales budget, a production manager the production budget, and so on.
The budget officer
The budget officer is usually the management accountant or the head of accounting. He or she coordinates the process on behalf of the committee. The functions are:
- Circulate the committee’s budget guidelines to all functional managers, so all prepare budgets within the same framework.
- Act as secretary to the committee: record minutes, keep communications and document decisions.
- Update and revise the budget manual as the committee directs.
- Design the forms, schedules and reports that standardise how budget data is collected.
- Receive and scrutinise the budgets submitted by functional managers, checking compliance with the guidelines and asking for changes where needed.
- Compile the reviewed budgets into the master budget.
- Circulate the approved budget to the functional managers who will implement it.
- Prepare monthly budgetary control reports comparing actual with budget, and send them to the committee and to the functional managers.
The budget manual
The budget manual is a comprehensive document of guidelines, instructions and procedures for the whole budgeting process. It is the main reference for everyone who prepares, approves or monitors budgets, and it makes the process consistent, accurate and aligned with organisational goals. Typical contents:
| Section | What it covers |
|---|---|
| Purpose and objectives | The role of the budget in achieving financial and strategic goals, and how budgeting improves planning, control and decisions |
| Policies and principles | The time frame (for example annual budgets), the methods to be used (for example incremental or zero-based budgeting) and expectations for reporting and accountability |
| Roles and responsibilities | Who prepares, reviews, approves and monitors: the committee, budget officers, department heads and others |
| Preparation process | Step-by-step instructions: collecting data, setting assumptions, forecasting revenues and costs, completing forms, submitting and reviewing |
| Control procedures | How actual performance is compared with the budget, how variances are identified and how corrective action is taken. How budget holders manage resources within limits |
| Reporting requirements | Which reports, how often and in what format, such as periodic control reports and variance analysis |
| Approval and amendment | How the budget is approved and who may change it during the year if circumstances change |
| Tools and templates | Standard forms and schedules so that all information is captured in the same way |
The principal budget factor
The functional budgets must be coordinated and consistent. To ensure this, the first one prepared is the budget for the principal budget factor (also called the key budget factor): the factor that will limit the volume and scale of the organisation’s activities in the budget period.
- Sales demand. Normally the principal budget factor is the expected demand. It sets a limit on how much should be produced, because making more than can be sold serves no purpose. When sales demand is the factor, the sales budget is prepared first.
- Another factor. There may be a shortage of a key resource, such as machine time, skilled labour or materials. If it limits production below the level of demand, the first budget to prepare is the budget for that resource.
- Government. A government department often faces an expenditure limit, so it must plan its activities within the total allowed.
Example. A bakery can sell 15,000 loaves a month at its current prices. Its oven can bake only 12,000 loaves a month. Demand (15,000) is above capacity (12,000), so the oven capacity, not sales demand, is the principal budget factor. The bakery builds its budgets round 12,000 loaves, starting with the production budget. If the baker adds a second oven, demand becomes the limiting factor again.
The principal budget factor can change from year to year. A business that grows beyond its factory space may find that capacity limits it this year, while next year the new factory moves the limit back to the market.
Stages in the budget process
The process for a manufacturing company is the most complex, and is the one most often examined. The stages are:
| Stage | What happens |
|---|---|
| 1. Identify the principal budget factor | Recognise the element that limits activity in the period, often sales volume. All other budgets are developed round it |
| 2. Prepare the budget for the key factor | Usually the sales budget, drawn up first. Other budgets must stay within the limits it sets. Production, for example, should not plan to exceed projected sales unless there is a decision to build up stock |
| 3. Prepare the other functional budgets | Inventory budgets (planned increases or reductions), production budget, labour budgets, materials usage and purchases budgets, and expenditure budgets for production, administration and selling and distribution overheads. They are usually prepared by cost centre, in a logical sequence |
| 4. Submission and review by the budget committee | The committee checks that each budget is realistic, consistent with the others and feasible |
| 5. Compile the master budget | Summarise the whole plan: a budgeted income statement, a budgeted statement of financial position and a cash budget (or cash flow forecast) |
| 6. Final approval by the board | The board reviews and formally authorises the master budget and its supporting functional budgets |
| 7. Communication to responsible managers | Approved budgets go to the managers who will implement them |
| 8. Control: monitoring and variance analysis | Actual performance is tracked against the budget. Variances are investigated, reasons found and corrective action taken, holding managers accountable |
Planning (budgeting) must lead on to monitoring and control (budgetary control). In practice, budgets are prepared on spreadsheets or computer models, but you need to understand the logic of how they are built.
The functional budgets
A functional budget is a budget for one aspect of operations. In a manufacturing company they include a sales budget; a production budget; budgets for production resources and their costs (materials usage and labour); a materials purchases budget; and expenditure budgets for every overhead cost centre and for general overhead. The master budget is the final approved budget that combines them all. The next topics show how each is prepared.
Background: three further points often examined
Background: the syllabus mentions these terms only briefly or not at all, but examination papers have tested them.
Fixed and flexible budgets
A fixed budget is set for one level of activity and not changed. A flexible budget is recalculated for the level of activity actually reached, so that actual costs are compared with what they should have been at that activity. The budget cost allowance for a given activity is: fixed costs + (variable cost per unit × units).
Example. A department’s budget is: fixed costs ₦60,000 and variable costs ₦12 per unit, at a planned activity of 4,000 units. Budget cost = ₦60,000 + (4,000 × ₦12) = ₦108,000. Actual activity was 4,500 units and actual cost ₦118,000.
- Against the fixed budget.
₦118,000 − ₦108,000 = ₦10,000 adverse.
This is misleading, because more units were made. - Flexed budget for 4,500 units: ₦60,000 + (4,500 × ₦12) = ₦114,000.
Variance = ₦118,000 − ₦114,000 = ₦4,000 adverse.
This is the true overspend.
Types of budgeting
| Type | Idea | Strength | Weakness |
|---|---|---|---|
| Incremental | Last year’s budget plus or minus a percentage for inflation and known changes | Simple and quick | Carries past inefficiency forward |
| Zero-based | Every item must be justified from zero each year | Challenges waste and priorities | Time-consuming and costly |
| Rolling (continuous) | A new period is added as each one ends, so there is always a full-length budget | Keeps the plan up to date | Effort of constant revision |
Human aspects of budgeting
- Participation. Managers who help set their budgets are more likely to accept and meet them.
- Realistic targets. Targets that are too easy give no motivation; those that are impossible demotivate. A moderately challenging target works best.
- Budgetary slack. Managers may pad budgets (ask for ₦500,000 when they need ₦450,000) to make targets easy. The padding wastes resources and hides the true cost.
- Controllability. Managers should be judged on costs they can influence. Holding them responsible for costs decided elsewhere causes resentment.
- Feedback and fairness. Prompt, constructive reports help. Using the budget only to blame managers encourages them to hide problems.
The ideas in more depth
Budget, forecast and plan
A forecast says what is likely to happen. A budget says what management intends to happen, with commitment to resources and responsibility. A good budget starts from a forecast but includes management decisions to change the outcome, such as a price cut or a marketing push.
Why the principal budget factor comes first
Suppose production planned 20,000 units, sales expected to sell only 15,000, and purchasing bought materials for 20,000. The business would finish the year with 5,000 unsold units and the cash locked up in them. Starting from the limiting factor makes each later budget consistent: production is built from sales, purchases from production, and cash from them all.
Budgeting as a communication and negotiation process
A budget is built from the bottom up (managers propose) and the top down (the board sets guidelines). The committee reconciles the two. Where a manager’s proposal does not fit with the whole, the committee asks for changes. The result is a compromise that every manager understands and has accepted.
Control periods and reporting
Splitting the year into months means that variances are spotted quickly, while action can still change the outcome. A report in month 11 showing that the first month overspent helps nobody. The budget officer’s monthly reports to the committee and the functional managers supply the information for action.
Limitations of budgeting
- It takes time and money.
- It can make managers spend what is left in the budget at the year end, to avoid a cut next year.
- It can be rigid in a fast-changing environment unless revised.
- Targets set too high or too low reduce motivation.
- It depends on forecasts, which are uncertain.
Worked example: choosing the factor and sequencing the budgets
Scenario. Ilorin Pumps Ltd expects demand of 6,000 pumps next year. The factory has 14,400 machine hours available, and each pump needs 2 machine hours. Skilled welders are available to make up to 8,000 pumps. Identify the principal budget factor, say which budget is prepared first, and list the order of the others.
- Limits by factor. Demand: 6,000 pumps.
Machine hours: 14,400 ÷ 2 = 7,200 pumps.
Labour: 8,000 pumps. - Principal budget factor. The lowest limit is demand, 6,000 pumps. Sales demand is the principal budget factor.
- First budget. The sales budget (6,000 pumps × selling price).
- Order of the rest. Finished goods inventory plans, then production budget (sales ± change in stock), then labour and materials usage budgets, then the materials purchases budget (usage ± change in material stock), then expenditure budgets for production, administration and selling overheads, then the cash budget and the master budget.
- If demand grew to 9,000. The limit would then be machine hours (7,200 pumps), which would become the principal budget factor, and the production budget would be prepared first.
Common mistakes in the exam
- Listing the stages of the budget process in the wrong order, or leaving out the committee review and the board approval.
- Saying the principal budget factor is always sales. It is usually sales, but it is whatever limits activity.
- Confusing the budget committee (supervises and approves) with the budget officer (coordinates and reports).
- Giving the purposes of budgeting as one-word labels without explaining them.
- Describing budgeting as the same as forecasting. A budget is a plan with commitment.
- Forgetting that budgets must lead on to control and variance analysis.
- Writing that the sales budget is always prepared first even when another factor limits activity.
Quick revision
- Planning levels: long-term strategic (3 to 5 years); medium-term tactical (1 to 2 years, budgets); short-term operational (weeks or months).
- Budget = formal financial plan for all activities, usually a year, in control periods.
- Purposes: convert plans to actions, link to strategy, coordinate, communicate, motivate, authorise spending, define responsibility, benchmark, allocate resources, control cost, support decisions.
- Budget committee supervises. Budget officer coordinates and reports. Budget manual sets the rules.
- Principal budget factor limits activity. Prepare its budget first.
- Eight stages: factor; key budget; other functional budgets; committee review; master budget; board approval; communication; control.

Model answers
Show the model answer to Question 11
(1) It converts long-term plans into short-term actions, breaking a strategy into detailed annual plans. (2) It coordinates the departments (goal congruence), so that production, purchasing and sales work to the same plan. (3) It communicates plans to the managers and staff who must carry them out. (4) It motivates by setting clear targets, often with rewards for meeting them. (5) It authorises expenditure only within approved amounts, which promotes discipline.
(6) It provides a benchmark for evaluating performance through variance analysis. (7) It allocates resources to priority areas and helps control costs. Any five are acceptable if each is explained.
Show the model answer to Question 12
(a) The principal budget factor, also called the key budget factor, is the factor that limits the volume and scale of the organisation’s activities in the budget period. Examples: sales demand (the usual factor); a shortage of machine time; a shortage of skilled labour; or, for a government department, an expenditure limit.
(b) Stages. (1) Identify the principal budget factor. (2) Prepare the budget for that factor, usually sales. (3) Prepare the other functional budgets: inventory, production, labour, materials usage and purchases, and overhead expenditure budgets. (4) The budget committee reviews them for realism and consistency. (5) The master budget is compiled: a budgeted income statement, statement of financial position and cash budget. (6) The board approves the master budget.
(7) The approved budgets are communicated to responsible managers. (8) Actual performance is monitored against budget, variances are investigated and corrective action is taken.
(c) The budget committee, made up of senior managers from the main areas, supervises the process. It reviews the functional budgets, checks they are consistent and instructs changes. The budget officer, normally the management accountant, coordinates the process on its behalf: circulating guidelines, acting as secretary, updating the budget manual, designing forms, scrutinising submitted budgets, compiling the master budget, circulating the approved budget and preparing monthly control reports.
(d) Any three of: purpose and objectives; budgeting policies and principles; roles and responsibilities; the preparation process; control procedures; reporting requirements; approval and amendment procedures; tools and templates.
Show the model answer to Question 13
(a)
- Fixed budget cost.
₦90,000 + (5,000 × ₦20) = ₦190,000. - Actual cost ₦209,000, so the variance against the fixed budget = ₦19,000 adverse.
- Flexed budget for 5,600 units = ₦90,000 + (5,600 × ₦20) = ₦202,000.
- Variance against the flexed budget.
₦209,000 − ₦202,000 = ₦7,000 adverse.
(b) The fixed comparison ignores the fact that more units were made, so part of the ₦19,000 (₦12,000) is simply the extra cost of extra output. The flexed comparison compares actual cost with what the cost should have been at the actual activity, so it shows the real overspend that management can control.
(c) Budgetary slack, where managers pad their budgets; unrealistic targets that demotivate; holding managers responsible for costs they cannot control; or lack of participation, which reduces acceptance of targets. (Any two.)
