Episode 2: Rolling Budgets vs. Zero-Based Budgeting – Which Approach Is Right for Your Strategy?

Introduction: As you prepare for the new fiscal year, one critical decision is determining the right budgeting method to use. In this episode, we'll explore two popular approaches: Rolling Budgets and Zero-Based Budgeting (ZBB). Each method has its merits and drawbacks, and the key to success lies in aligning the approach with your company's unique strategy and business goals.

1. Understanding Rolling Budgets:

What is a Rolling Budget? A Rolling Budget is an incremental approach where the budget is continuously updated. Every quarter or month, the budget rolls over, incorporating the latest financial data to make real-time adjustments. This approach allows for a more dynamic financial plan, accommodating changes and market fluctuations as they arise. While this method allows for flexibility, it can also pose a risk of cost overruns if not closely monitored. As departments adjust their budgets throughout the year, unexpected costs or underestimations can lead to budget shortfalls, impacting cash flow and overall financial health.

When to Use Rolling Budgets: Rolling Budgets work best for fast-paced industries or companies in growth phases, where flexibility is essential, and strategic pivots are frequent. For example, a tech company expanding into multiple regions or launching new products regularly benefits from the agility of rolling budgets.

Advantages of Rolling Budgets:

• Flexibility to adjust to market conditions and unforeseen challenges.
• Continuous alignment with strategic goals and real-time performance.
• Better cash flow management, as adjustments can be made to avoid overspending during low-revenue periods.

Risk of Cost Overruns: In a Rolling Budget system, without proper cost controls in place, a company may find itself overcommitting resources early in the year. Departments may not anticipate all costs upfront or may be overly optimistic in forecasting, leading to less financial discipline than a more rigid system like ZBB. Controllers must continuously monitor to avoid creeping costs that may be missed.

2. The Case for Zero-Based Budgeting (ZBB):

What is Zero-Based Budgeting? Zero-Based Budgeting starts from scratch each fiscal year. Every expense must be justified, forcing departments to evaluate their needs critically and avoid unnecessary spending. This provides clear visibility into operational spending, giving controllers greater control over resource allocation. For companies with stable, clear strategic goals, ZBB is often the preferred approach, as it aligns every dollar with the company's overall objectives. Unlike traditional methods, where last year's numbers are used as a baseline, ZBB focuses on prioritizing resources based on current needs and future goals.

When to Use Zero-Based Budgeting: ZBB is ideal for companies undergoing restructuring, significant shifts in strategy, or cost-cutting initiatives. Industries facing market volatility or high competition, such as retail or manufacturing, often adopt this method to control expenses effectively.

Advantages of Zero-Based Budgeting:

• Forces cost discipline by requiring justification for each line item.
• Provides clear visibility into spending priorities and aligns directly with strategic goals.
• Useful for cost-saving initiatives, as unnecessary expenditures are trimmed early on.

Clear Plan and Operational Control: ZBB gives management and financial controllers a roadmap for the year. With strategic objectives set and budget allocations clearly defined, ZBB minimizes the risk of unexpected expenditures. For example, a company with long-term growth targets (like a new product line or market entry) can set its budget in a way that ensures all necessary resources are allocated upfront.

3. Comparing the Two Approaches:

Rolling Budgeting: Best suited for organizations that require ongoing adjustments, especially in fast-moving industries like tech or startups. It allows for flexibility but may lack the cost discipline of ZBB.

Cost Overrun Risk: Rolling Budgets offer flexibility but come with the risk of cost overruns if there’s inadequate financial discipline. Companies using Rolling Budgets must establish strong tracking mechanisms and have controllers monitor costs closely throughout the year to avoid spending beyond their limits.

Zero-Based Budgeting (ZBB): Ideal for companies looking to tighten their belts or undergoing significant restructuring. It ensures that every dollar spent is justified, but it can be time-intensive and challenging to manage in dynamic environments.

Strategic Visibility: ZBB provides clear operational control. Since every expense must be justified and tied to a strategic goal, it allows for better predictability in spending. External investors often appreciate the transparency ZBB offers, as it demonstrates a strong link between the company’s strategic vision and its financial planning.

4. External Investor Perspective:

Rolling Budgets – Flexibility but Risk: Investors might appreciate the flexibility of Rolling Budgets for companies in fast-growing industries, as they allow for real-time adjustments to spending based on evolving business needs. However, investors may also be concerned about budget overruns if proper financial oversight isn’t in place. Rolling Budgets can be seen as riskier if not supported by strong cost controls.

Zero-Based Budgeting – Investor Confidence through Discipline: Investors often favor ZBB when a company’s strategy is more stable and long-term, as it shows a disciplined approach to financial management. ZBB reassures investors that every dollar is justified and that there is little room for wasteful spending. For companies looking to attract investors, showing that their ZBB aligns with well-defined strategic goals can be a major confidence booster.

5. Key Considerations When Choosing Your Approach:

• Strategic Alignment: Does your organization require continuous adjustments (Rolling) or a complete re-evaluation of costs (ZBB)?
• Resource Availability: Do you have the resources (financial and personnel) to justify every expenditure in ZBB, or does a rolling budget provide the flexibility your company needs?
• Current Business Climate: Consider market conditions, company growth stage, and strategic goals. A high-growth phase may require more flexibility, while a period of restructuring may benefit from the discipline of ZBB.

6. Real-World Example: How One Company Decided

A mid-sized tech company expanding globally initially followed a Rolling Budget model for flexibility to scale up operations. However, after facing cost overruns in several departments, they transitioned to a hybrid model. They incorporated ZBB for key projects like R&D and marketing while keeping Rolling Budgets for operational expenses. This dual approach allowed them to control costs in critical areas while maintaining flexibility where needed.

Conclusion:

Choosing the right budgeting method is not just a financial decision—it’s a strategic one. Both Rolling Budgets and Zero-Based Budgeting offer unique advantages, and the key lies in understanding your company’s needs. Whether you prioritize flexibility or fiscal discipline, the right approach will set the foundation for a successful year ahead.
