Purpose and value of budgeting

  • A budget is a financial plan that sets out expected income, spending or profit over a future period - typically a month, a quarter or a financial year

    • It gives managers a clear target to aim for and a benchmark against which actual performance can be measured

  • Budgets are prepared in advance and are based on the best available information about future trading conditions

Why budgeting is important

Budgeting is important for planning, control and communication

Planning

  • Preparing a budget forces managers to think carefully about the future

    • Forecasting sales, anticipating costs and identifying potential financial pressures before they arise

  • This helps the business to prepare for challenges rather than simply react to them

Control

  • Once a budget is set, actual performance can be compared against it at regular intervals

  • The difference between a budgeted figure and the actual figure is called a variance

    • Identifying variances early allows managers to investigate problems and take corrective action before they escalate

Coordination

  • Budgets help ensure that different departments within a business are working towards the same financial goals

    • For example, if the sales team plans to increase revenue by 20%, the production and logistics departments need to know this so they can plan their own spending accordingly

Motivation

  • Giving individual managers responsibility for their own budget can increase their sense of ownership and accountability

  • Having a clear target to work towards can be motivating

    • Particularly if managers are involved in setting the budget rather than simply having figures imposed on them

Communication

  • The budgeting process communicates financial priorities and expectations of senior management throughout the organisation

  • It ensures that everyone understands what the business is trying to achieve financially and what resources are available to them

Supporting decision-making

  • Budgets provide a financial framework for evaluating decisions

    • For example, if a manager wants to invest in new equipment or hire additional staff, the budget helps assess whether the business can afford it and what impact it will have on profit

Types of budget

  • Businesses typically use several different budgets, each focusing on a different aspect of financial performance

Businesses can set revenue, expenditure and profit budgets
  • In practice, these budgets are linked

    • A change in expected revenue will affect the profit budget

    • A rise in costs in one department will need to be reflected in the overall expenditure budget

Approaches to setting budgets

Incremental budgeting

  • Incremental budgeting uses the previous year's budget as a starting point and adjusts it by a set amount or percentage to reflect expected changes, such as inflation, anticipated growth, or planned cost increases

  • It is the most widely used approach in large organisations

Example

A marketing department had a budget of £80,000 last year.

Using incremental budgeting with a 5% increase for inflation, next year's budget would be set at £84,000 without necessarily reviewing whether every element of last year's spending was necessary

Benefits

Challenges

  • Quick and straightforward to produce

    • Managers are generally familiar with the process

  • Provides continuity and stability

    • It is easier for departments to plan ahead

  • Requires less time and detailed analysis than zero-based approaches

  • Works well in stable environments where spending patterns do not change significantly year to year

  • Tends to lock in past inefficiencies

    • If a department overspent or wasted money last year, that waste is built into next year's budget

  • Encourages departments to spend their full budget at the end of the year to avoid having it reduced

    • This is known as budget padding

  • Does not challenge the question of whether existing activities are still the best use of resources

  • Can result in poor allocation of funds

    • Growing areas of the business may be underfunded while declining areas retain historic spending levels

Zero-based budgeting

  • Zero-based budgeting starts from scratch every budget period

    • Rather than adjusting last year's figures, every department must justify all of its planned spending from zero, as if the budget were being set for the first time

  • No spending is automatically approved simply because it happened in a previous year

Example

A customer service department using zero-based budgeting cannot simply ask for last year's budget plus inflation

Instead, it must justify every cost, such as staffing levels, software subscriptions and training, by explaining what value each delivers to the business

Benefits

Challenges

  • Eliminates wasteful or outdated spending that has simply been carried forward from previous years

  • Encourages managers to think critically about how they use resources and prioritise the most valuable activities

  • Allocates funds based on current needs and priorities rather than historical patterns

  • Particularly effective when a business is restructuring, facing financial pressure or entering a new market

  • Extremely time-consuming and resource-intensive to produce

    • Managers must justify every line of expenditure in detail

  • Can be demotivating for managers who feel their decisions are being constantly questioned

  • Requires a high level of financial knowledge and analytical skill from managers across the organisation

  • May create short-term thinking

    • Managers focus on justifying immediate spending rather than planning for the longer term

Examiner Tips and Tricks

When evaluating budgeting approaches in an exam question, consider the context of the business. Zero-based budgeting may be superior at eliminating waste, but for a large organisation with hundreds of departments, the time and cost of implementing it fully may outweigh the benefits. Incremental budgeting is not necessarily a poor choice - it depends on the stability of the business and whether efficiency is the primary concern
