Should Your Budget be Flexible?

Creating a reliable budget is the first step in effective financial management.  Common advice on the internet tells you that your budget should be flexible, “a living document” that you revise each time circumstances change. Another variation of this guidance tells you to employ a “rolling budget.”  While seemingly reasonable, this well-intentioned advice diminishes the budget’s value as a stable benchmark for monitoring and measuring results. Benchmarking performance is one of the most vital roles of a budget. 

At the same time, you need to be flexible in reacting to situations not anticipated by your budget.  Well-managed businesses meet the competing needs for stability and flexibility with “the forecast.” A forecast is closely related to a budget.  The process for creating them is almost identical, as is the final product…a set of projected financial statements.  However, the differences are important, and they should be regarded as two separate tools.          

We will discuss why a stable budget is imperative, how forecasting complements but does not replace a budget, and the importance of clear communication in differentiating between the two. As we explore the roles of scenario planning, handling variances, and stakeholder communication, we will illustrate how a stable budget alongside a dynamic forecast forms the backbone of effective financial management.

The Role of a Business Budget

A business budget is a strategic plan that outlines a company’s financial expectations for the future. This plan serves several vital functions:

  1. Financial Roadmap: A budget is a financial roadmap, providing a detailed plan for income and expenditure over a specific period. It allows businesses to allocate resources effectively, ensuring that each department or project is adequately funded while keeping overall expenses within limits.
  2. Goal Setting and Performance Measurement: A budget sets financial goals for the company. These goals must be based on detailed analysis and realistic expectations. By comparing actual performance against the budget, businesses can gauge their progress and identify improvement areas.
  3. Resource Allocation and Prioritization: With a finite pool of resources, a budget helps in prioritizing expenditures. It forces management to make tough decisions, ensuring funds are allocated to areas with the highest return on investment or strategic importance.
  4. Control and Accountability: A budget acts as a control tool. It sets boundaries for spending, which helps prevent financial missteps and overspending. It also holds various departments accountable, ensuring they do not exceed their allocated funds without justification.

The effectiveness of a budget as a benchmark depends on its stability. If a budget is continually adjusted, it loses its role as a standard against which performance can be measured. This is like moving the goalposts during a game; it makes it impossible to assess performance or make meaningful comparisons over time.

Treating a budget as a “living document” that frequently changes also undermines the discipline of planning and fiscal responsibility. It can lead to a lax attitude towards spending and financial goals, as there is always the option to adjust the budget to match actual expenditures rather than striving to meet the set targets.

In the following section, we will explore how forecasting complements the budget by providing the flexibility and adaptability that a stable budget cannot and why it’s crucial to maintain a clear distinction between these two vital financial tools.

Forecasting: Complementing the Budget with Flexibility

While a stable budget is essential for setting benchmarks and long-term planning, the dynamic nature of business demands a tool that can adapt to real-time changes. This is where forecasting comes into play, acting as a flexible counterpart to the rigid structure of a budget.

  1. Definition and Role of Forecasting: Forecasting predicts a company’s future financial outcomes based on current trends and historical data. Unlike a budget set for a specific period, which remains largely unchanged, a forecast is continuously updated to reflect the latest market conditions, operational performance, and other relevant factors.
  2. Flexibility and Adaptability: The primary advantage of forecasting is its flexibility. As new data becomes available or circumstances change, the forecast can be adjusted to provide a more accurate picture of the company’s expected financial performance. This adaptability allows businesses to respond swiftly to market changes, seize emerging opportunities, or mitigate unforeseen risks.
  3. Forecasting as a Complementary Tool: It’s crucial to understand that forecasting does not replace a budget. Instead, it complements it. While the budget sets the financial targets and boundaries, the forecast provides an ongoing assessment of where the company is likely to end up if current trends continue. This dual approach allows businesses to maintain a consistent benchmark (the budget) while staying agile and responsive to short-term changes (the forecast).
  4. Clarity in Communication: One of the challenges in financial management is ensuring clarity in communication, especially when discussing the budget and forecasts with stakeholders, be it employees, investors, or partners. When the two are conflated or not distinguished, it can lead to confusion and misaligned expectations. For instance, if a forecast indicates that revenues are likely to fall short of the budgeted figures, stakeholders need to understand that this does not imply a change in the budget itself but rather an indication of where actual performance is tracking against it.
  5. Real-time Decision Making: Forecasts are invaluable for real-time decision-making. They enable businesses to make informed decisions based on current information, whether ramping up marketing efforts, adjusting pricing strategies, or reallocating resources. In a rapidly changing business environment, making well-informed decisions quickly can be a significant competitive advantage.

While the budget provides a stable framework for planning and performance measurement, forecasting offers the agility and adaptability needed to navigate the ever-changing business landscape. Next, we will delve into the importance of scenario planning and risk management within these financial practices, emphasizing how they can set realistic aspirations and manage variances effectively.

The Role of Aspirations and Ideals

A budget can encapsulate the aspirations of a business, translating goals into financial targets. This section explores how aspirations are integrated into the budgeting process and the importance of setting realistic, achievable goals.

Incorporating Goals into the Budget

  1. Setting Aspirational Targets: A budget may reflect not only the expected income and expenses but also the strategic ambitions of the business. These targets, whether revenue growth, market expansion, or cost reduction, should stretch the business’s capabilities without straying into impracticality.
  2. Goals and Standards: Budget goals and standards may be based on industry benchmarks, past performance, or a study of your processes.  You may decide that it should take three labor hours to produce each unit of your product, even though you currently use 3.5 hours.  This may be because your competitors can, because you have accomplished this in the past, or because you studied the steps involved and determined it was achievable.   
  3. Ideal Costs: Ideal costs may be used to set budget standards. Ideal costs reflect what is theoretically possible with the most efficient use of resources without any waste. They are not usually achievable in real-world conditions.  However, you may set standards for your performance based on an acceptable level of inefficiency.  A restaurant may study its recipes and ingredient costs and determine that, with no waste, its food cost would be 20% of sales.  The leadership may decide what waste is acceptable and budget food at 22% of revenue.
  4. Balancing Ambition with Realism: Balancing ambition and realism are key to effective budgeting. Goals should be challenging yet attainable, pushing the business to excel while remaining grounded in practicality.
  5. Scenario Planning: Create scenarios to show the consequences of missing a goal. Plan how to respond to variances.

Using the Budget as a Motivational Tool

  1. Measuring and Motivating Improvement: A budget can be a motivational tool for the team, setting clear objectives and providing a roadmap for achieving them. It is a constant reminder of what the business is striving to accomplish.
  2. A Goal Needs a Plan: Work with your teams to develop a sound plan to achieve any budgeted improvements.
  3. Regular Reviews and Adjustments: Regularly reviewing budget performance against actual outcomes can help maintain momentum and focus. Adjustments may be necessary, but these should be done thoughtfully and with consideration of the overarching strategic goals.

The Reality of the Forecast

  1. Reflecting Current Performance: While your budget may include goals and aspirations, your forecast should reflect current performance or re-evaluate goals based on reality.

Businesses can set a realistic yet challenging path toward financial growth and stability by effectively incorporating aspirations into the budget and managing variances thoughtfully.

Scenario Planning and Risk Management

Integrating scenario planning into budgeting and forecasting is a strategic approach to managing uncertainty and preparing for various business outcomes. This section delves into the significance of scenario planning and its role in effective risk management.

  1. Understanding Scenario Planning: Scenario planning involves developing different hypothetical situations to anticipate future events and their impacts on business performance. These scenarios range from optimistic to pessimistic, covering many possibilities. The objective is not to predict the future but to prepare by considering various plausible outcomes.
  2. Role in Budgeting: In the budgeting process, scenario planning helps identify potential risks and opportunities that could affect financial performance. A business can establish a more resilient and informed budget by exploring different scenarios during budget creation. This approach helps set achievable goals, even in the face of uncertainty. It enables businesses to foresee potential financial challenges and opportunities, allowing for the creation of contingency plans.
  3. Incorporation into Forecasting: Scenario planning plays a dynamic role in forecasting. As forecasts are updated to reflect current trends and data, incorporating scenario planning allows businesses to continuously assess the impact of changing market conditions, operational shifts, or external factors. This ongoing evaluation assists in anticipating future financial states and making timely strategic decisions.
  4. Risk Management through Realistic Aspirations: A critical aspect of scenario planning is setting realistic and achievable aspirations within the budget. Unrealistic goals can lead to frustration and demotivation, while achievable targets foster a sense of accomplishment and progress. Realistic ambitions, backed by strategic planning and risk assessment, ensure the budget is ambitious and attainable.
  5. Managing Variances with Informed Responses: Variances from the budget are inevitable, but scenario planning helps understand the nature and implications of these variances. Distinguishing between controllable and uncontrollable variances is crucial. For controllable variances, businesses can implement corrective actions. For uncontrollable ones, understanding their impact enables enterprises to adjust forecasts and strategies accordingly without altering the budget.
  6. Enhancing Decision-Making and Preparedness: Combining scenario planning with budgeting and forecasting enhances decision-making capabilities. It prepares businesses to face various situations, reducing the shock of unexpected events and providing a framework for swift and informed responses.

Thus, Scenario planning is a critical tool in budgeting and forecasting, enhancing a business’s ability to manage risks, set realistic goals, and make informed decisions. In the following section, we will explore handling variances in budget and forecasts, focusing on different responses to controllable and uncontrollable variances and the implications for business decision-making.

Handling Variances in Budget and Forecasts

Variances in business finance are differences between what was budgeted or forecasted and what occurred. Understanding and appropriately responding to these variances is crucial for maintaining financial health and making strategic decisions. This section discusses how to effectively manage these variances in the context of both the budget and forecasts.

  1. Expect Variances: First and foremost, it is essential to acknowledge that variances are a normal part of business operations. No budget or forecast can predict the future with absolute accuracy. Variances should be expected, and their occurrence does not necessarily indicate a problem. Instead, they provide valuable insights into business performance and market dynamics.
  2. Analyzing Variances: It is essential to understand why a variance occurred – whether due to internal factors (like operational efficiency or cost control) or external factors (such as market changes or economic conditions). This analysis helps in distinguishing between controllable and uncontrollable variances.
  3. Controllable Variances: Controllable variances can be influenced by the business’s actions or decisions. For example, if marketing expenses are higher than budgeted, the company can look into ways to optimize marketing strategies or negotiate better rates. Here, the focus should be on understanding the root cause and implementing corrective actions to align future spending with the budget.
  4. Uncontrollable Variances: Uncontrollable variances occur due to factors outside the business’s control, like sudden market shifts or regulatory changes. While these cannot be controlled, their impact can be managed. This involves adjusting the forecasts to reflect new realities and revising strategies to mitigate risks or capitalize on unexpected opportunities.
  5. Role of Forecasting in Managing Variances: Forecasting plays a vital role in managing variances. As new data becomes available and variances emerge, forecasts can be updated to provide a more accurate picture of the company’s financial trajectory. This helps make informed decisions about resource allocation, operational changes, and strategic planning.
  6. Communication and Stakeholder Management: Communication about variances is critical, especially with stakeholders. Explaining the reasons for variances and the steps to address them helps maintain trust and confidence. It’s important to distinguish between budget and forecast variances in these communications to avoid confusion.
  7. Learning and Improvement: Finally, variances, both positive and negative, offer learning opportunities. Analyzing variances can reveal insights into business operations, market dynamics, and the effectiveness of strategies. This analysis can refine future budgets and forecasts, improving the accuracy and reliability of these financial tools.

Handling variances in budgets and forecasts involves analysis, response, communication, and continuous learning. Businesses can maintain financial stability and adapt to changing circumstances by effectively managing these variances. Next, we will explore the budget creation process. We will discuss how different scenarios can be modeled to identify risks and opportunities and how one base case is decided upon as the budget.

The Budget Creation Process

Developing a business budget is a systematic process that requires careful planning, analysis, and consideration of various factors. This section outlines the key steps in the budget creation process, emphasizing the modeling of different scenarios to identify risks and opportunities and culminating in selecting a base case for the budget.

  1. Gathering Historical Data: The first step in budgeting is to gather and analyze historical financial data. This data provides a baseline for understanding past performance and trends, which is crucial for making informed projections.
  2. Understanding Business Goals and Objectives: Aligning the budget with the company’s strategic goals and objectives is essential. This alignment ensures that the budget supports the overall direction and priorities of the business.
  3. Revenue ForecastingEstimating future revenue is a critical budget component. This involves analyzing market trends, current sales pipelines, and potential growth opportunities. Revenue forecasting sets the foundation for how resources will be allocated.
  4. Expense Forecasting: Alongside revenue, forecasting expenses is vital. This includes fixed costs (like rent and salaries) and variable costs (like raw materials and marketing expenses). A thorough understanding of expenses helps in controlling costs and improving profitability.
  5. Scenario Modeling: This is where the budget begins to take shape. Scenario modeling involves creating different “what-if” scenarios, such as best-case, worst-case, and most-likely scenarios. This process helps understand the potential impacts of various business conditions and decisions.
  6. Risk Assessment and Opportunity Identification: Identifying potential risks and opportunities is crucial to scenario modeling. This step involves considering internal and external factors that could impact the budget, such as market conditions, regulatory changes, or operational challenges.
  7. Selecting a Base Case: After analyzing different scenarios, a base case is selected for the budget. Considering the current business environment and foreseeable future conditions, this base case represents the most realistic and probable outcome.
  8. Setting Goals and Benchmarks: The budget should include specific, measurable goals and benchmarks. These goals serve as targets for the business to strive towards and are essential for tracking performance.
  9. Review and Approval: The final step in the budget creation process is the review and approval by key stakeholders, such as business owners, department heads, and, sometimes, board members. This step ensures the budget aligns with broader business objectives and has the necessary implementation support.
  10. Communication and Implementation: The budget should be communicated clearly to all relevant parties once approved. Effective implementation requires that everyone understands the budget and their role in achieving it.

Budget creation combines art and science, requiring quantitative analysis and qualitative judgment. By following these steps, businesses can develop a budget that serves as a reliable financial roadmap, guiding them toward their strategic objectives.

The Dynamic Role of Forecasts

Forecasts are pivotal in business, reflecting current trends and performance. This section explores the dynamic nature of forecasts, how they differ from budgets, and their significance in strategic business planning.

  1. Forecast as a Reflection of Current Trends: Unlike a budget, which is a set plan for a specific period, the forecast changes based on current business realities. It is continually updated to reflect new information, such as changes in market conditions, customer behavior, or operational efficiencies. This real-time reflection gives businesses an up-to-date view of their financial trajectory.
  2. Adaptability of Forecasts: One of the critical strengths of forecasting is its adaptability. As businesses encounter new challenges or opportunities, forecasts can be adjusted to provide a more accurate picture of future financial performance. This flexibility allows for quick responses to changing business environments, ensuring that the company remains agile and competitive.
  3. Forecasting Process and Tools: Forecasting involves analyzing financial data, market trends, and historical performance. Advanced tools and software can be used to model various scenarios and predict outcomes. Though similar to budgeting, this process is more frequent and iterative, reflecting ongoing changes and updates.
  4. Role in Decision Making: Forecasts are crucial for short-term and mid-term decision-making. They provide valuable insights that help business leaders make informed decisions about resource allocation, strategic initiatives, and operational adjustments. Forecasts enable businesses to capitalize on favorable trends and mitigate potential risks.
  5. The Evolving Nature of Forecasts: Unlike static budgets, forecasts are expected to evolve. As each period passes, previous forecasts may be replaced with new ones incorporating the latest data and assumptions. This changing nature ensures that forecasts remain relevant and valuable for current decision-making.
  6. Alternate Scenarios in Forecasting: Forecasts often include alternate scenarios, which provide a range of possible outcomes based on different assumptions. These scenarios help businesses prepare for uncertainties and develop flexible strategies to handle various potential future states.
  7. External Communication and Guidance: While budgets may be shared with external stakeholders like investors and banks, forecasts are primarily used for internal management. However, forecasts can also be used for external communication, providing guidance on expected financial performance relative to the budget, such as earnings projections or anticipated market growth.
  8. Distinction from Budgets: Maintaining a clear distinction between budgets and forecasts is crucial. While the budget is a guide and benchmark, the forecast is an interactive decision tool.

Forecasts play a critical and dynamic role in business. They complement budgets by providing flexibility and adaptability for effective short-term and mid-term planning. Understanding and utilizing both tools effectively is vital to successful financial management and strategic decision-making.


A well-structured budget and a responsive forecast are strategic assets in a business’s toolkit. By understanding and utilizing each for its intended purpose, companies can navigate the complexities of financial management with greater confidence and clarity, driving toward success.
