The Ultimate Guide to Zero-Based Budgeting (ZBB) in 2024

What is Zero-Based Budgeting? 

Zero-based budgeting, or ZBB, is a method where organisations build their budgets from zero each period, justifying every cost. Unlike traditional budgeting – where historical data is the foundation – ZBB treats every new period as unique, requiring a detailed analysis of each expense to ensure it's necessary. This approach can lead to more granular, thoughtful budgeting, which can identify inefficiencies or outdated expenditures. The strategy has successfully been implemented by large companies such as Unilever, Kraft Heinz, and 3G Capital who have famously used ZBB to streamline operations and reduce costs. 

Zero-Based Budgeting’s Popularity 

ZBB has gained popularity in recent years, although its adoption has varied depending on industry and economic conditions. Its popularity tends to increase during times of economic uncertainty, such as during recessions or financial crises. It allows companies to scrutinize every expense and eliminate unnecessary costs, which is especially appealing when profit margins are tight, or cost-cutting measures are necessary.  

The rise of sophisticated financial planning tools has also made ZBB more accessible. Previously, the process was seen as time-consuming and labour-intensive. However, with modern cloud-based platforms and financial planning and analysis (FP&A) solutions, companies can implement ZBB more easily, using data analytics to automate parts of the process. 

Zero-Based Budgeting vs. Traditional Budgeting 

While traditional budgeting uses historical data as a baseline and applies incremental changes, zero-based budgeting starts fresh every period. The key differences include: 

Pros of Zero-Based Budgeting 

1. Cost Efficiency 

By eliminating automatic budget increases, ZBB can help organisations cut unnecessary costs, leading to leaner operations. It focuses spending on essential activities that drive revenue. 

2. Enhanced Strategic Alignment 

ZBB ties every dollar spent to the company’s strategic goals, ensuring that resources are allocated where they can generate the most value. 

3. Increased Accountability 

ZBB promotes transparency and accountability. Managers must justify their spending, which leads to more thoughtful and responsible budget proposals. 

4. Flexibility 

Unlike traditional budgeting, which often locks organisations into predetermined spending levels, ZBB allows for flexibility, making it easier to adapt to changing market conditions or strategic shifts. 

Cons of Zero-Based Budgeting 

1. Time-Consuming 

Implementing ZBB requires significant resources, including time and staff, to review and justify every expense. This makes the budgeting process more time-consuming than traditional methods. 

2. Short-Term Focus 

The focus on cost-cutting can sometimes encourage managers to prioritize short-term savings over long-term investments, such as research and development (R&D), which could hinder innovation. 

Is Zero-Based Budgeting Right for Your Organisation? 

Zero-based budgeting can be a game-changer for businesses looking to optimise their spending and improve financial discipline. However, it’s best suited for organisations that have the resources and commitment to manage the process. For companies that face rapid changes in the market or are focused on strategic growth, ZBB’s flexibility and focus on cost-efficiency can be highly beneficial. 

While ZBB is popular in certain industries like manufacturing, retail, and FMCG (fast-moving consumer goods), it may be less common in sectors like R&D-heavy industries, where long-term investments and innovation are critical. As mentioned above, ZBB can sometimes lead to a focus on short-term cost savings at the expense of long-term strategic goals. 

How to Implement Zero-Based Budgeting 

Implementing zero-based budgeting might seem daunting, but with a structured approach, it can deliver significant benefits. Here’s how to get started: 

1. Start from Zero 

In ZBB, each department must begin by justifying its entire budget from scratch. This process eliminates assumptions based on last year's numbers and forces a critical inspection of every cost. 

2. Identify Key Functions and Costs 

Break down the organisation into functional areas and outline the activities necessary for achieving business objectives. From there, list the associated costs and group them based on priority and necessity.

3. Justify Every Expense

Each department must provide a justification for every line item. This involves showing the return on investment or how the expense aligns with strategic goals. Costs that don’t deliver value are either reduced or eliminated.

4. Prioritise Expenditures

After the justification process, rank expenditures based on importance. This ensures that essential activities are fully funded, while less critical ones might be scaled back or cut entirely. 

5. Review and Approve

Managers review all the submitted budgets, cross-check for alignment with overall business goals, and make necessary adjustments. Once satisfied, they approve the final budget.
