What is budgeting?

At a glance

• Enables the ongoing control of actual values against planned values and detects variances at an early stage.
• Regulates which areas receive which resources and thereby creates priorities and responsibilities.
• The budgeting process synchronizes departments and promotes company-wide coordination.
• Annual budgets are increasingly being supplemented by flexible approaches such as rolling forecasts or beyond budgeting.

Budgeting definition

In a business sense, budgeting refers to the structured process of drawing up, approving and controlling budgets. A budget is a plan expressed in monetary terms that is assigned to an area of responsibility – such as a department, a project or a business unit – for a specific period.

Budgeting is a central element of operational controlling. It links the strategic specifications of company management with day-to-day operations and creates the basis for financial goals not only to be formulated but also to be pursued, measured and managed.

At its core, budgeting answers three questions:

• What is to be achieved in a given period?
• With what means is this to be achieved?
• Who bears responsibility for it?

Why is budgeting important? – Goals and functions of budgeting

Budgeting fulfills several functions in a company at the same time:

• Planning function: Budgets force a forward-looking examination of goals, measures and resources. They make implicit expectations explicit and quantifiable.
• Coordination function: Budgeting processes allow the plans of different areas to be aligned with one another. Dependencies – for example between sales, production and purchasing – thus become visible and are planned consistently.
• Motivation and incentive function: Budgets define binding goals against which managers and employees are measured. They create personal responsibility and can be linked to compensation or bonus systems.
• Control function: During the ongoing year, budgeting enables the target/actual comparison: actual results are set against the planned values, variances are analyzed and countermeasures are initiated.
• Communication function: The budgeting process is a company-wide dialogue. It clarifies the priorities that company management sets and provides orientation to the various areas.

How does a budgeting process work?

A typical budgeting process comprises the following phases:

• 1. Preparation and framework specifications: Company management defines strategic guidelines: growth goals, investment priorities, return targets. These are fed into the process as top-down specifications.
• 2. Decentralized planning (bottom-up): Departments and cost centers develop their budget proposals on the basis of the specifications – personnel costs, material costs, investments, revenues.
• 3. Consolidation and coordination: Controlling consolidates the partial plans into an overall budget, checks consistency, identifies gaps and initiates coordination rounds.
• Approval: The consolidated budget is approved by the management or executive board and set as a binding basis for the following year.
• 4. Budget control and reporting: Actual values are recorded monthly or quarterly and compared with the budget. Variance analyses flow into management reporting.
• 5. Forecast and adjustment: In the event of significant variances or changed circumstances, the forecast is updated – without changing the original budget.

What types and methods of budgeting are there?

What are the opportunities and risks of budgeting?

Opportunities

• clear goal commitment and responsibilities
• transparency about resource use and cost drivers
• comparability through a uniform planning basis
• basis for variance analyses and management impulses

Risks

• high time expenditure: budgeting processes often take 3 to 6 months
• past orientation: extrapolated budgets rarely reflect real strategic priorities
• "gaming" effects: departments deliberately plan conservatively to reach goals safely
• inflexibility: annual budgets quickly lose their validity in volatile markets
• silo thinking: departmental optimization instead of overall optimization

Budgeting in transition: What does modern budgeting look like?

Volatile markets, shorter planning cycles, and increasing complexity are increasingly calling the classic annual budget into question. Companies are looking for approaches that respond more quickly to changes, are less politically shaped, and retain real management relevance. Two models have become established in practice.

Rolling Forecast: Planning that keeps pace with reality

With the rolling forecast, the planning horizon is regularly extended by one period – usually monthly or quarterly – so that a consistently long outlook of, for example, 12 or 18 months always exists. Instead of explaining variances from the annual budget, the central question is: Where are we today – and where will we end up?

Beyond Budgeting: The radical restart

The Beyond Budgeting model – shaped by the Beyond Budgeting Round Table (BBRT) – goes a step further and fundamentally questions the classic budgeting process. Instead of fixed annual goals, it relies on relative targets (e.g., market or competitive benchmarks), decentralized decision-making responsibility, and an adaptive, demand-driven allocation of resources.

The model is particularly suitable for companies that define agility, individual responsibility, and fast responsiveness as strategic priorities.

Practical example: A modern budgeting process in a midsize company

A midsize machine manufacturer modernizes its budgeting process – without abandoning the proven counterflow method, but with significantly more flexibility and speed.

This is how the process works with modern budgeting in DeltaMaster:

In September, corporate management sets strategic benchmark figures – revenue growth +8 %, EBIT margin 9 %, investment framework €4 million. The cost centers then plan personnel costs, material costs, and investment needs. Controlling consolidates all sub-plans in DeltaMaster, performs automated plausibility checks, and identifies budget gaps in three areas. After two rounds of coordination, the budget is adopted in November.

The decisive difference lies in the ongoing year: Starting in January, actual values are automatically pulled from the ERP system, prepared in the plan/actual comparison, and commented on. Variances above a defined threshold of 10 % trigger countermeasure planning. On a quarterly basis, controlling updates the forecast – rolling, without looking back at the annual budget.

Result: After the introduction of DeltaMaster, the planning effort dropped by 35 %, the quality of the commentary improved measurably, and management receives budget reports within two working days after the monthly close – instead of after three weeks as before.

Application examples: Where is budgeting used?

Budgeting accompanies nearly all areas of a company. The following examples show typical fields of application in practice.

Summary

Budgeting is far more than an annual set of figures – it is a strategic management instrument that makes goals binding, directs resources and creates responsibility. In view of growing market dynamics, flexible approaches such as rolling forecasts are gaining importance without replacing the basic principles of budgeting. Those who consistently link budgeting with modern BI software like DeltaMaster shorten processes, improve data quality and gain genuine management capability.
