Zero-based budgeting (ZBB), also known as zero cost budgeting, is a financial strategy where every department or function start from scratch each budgeting period. Instead of automatically increasing last year’s budget, every expense must be justified – an approach that can drive cost efficiency, prevent unnecessary spending, and align expenses with strategic goals.
In this article, we’ll go over:
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 This approach can lead to more granular, thoughtful budgeting, which can identify inefficiencies or outdated expenditures.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 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.
While traditional budgeting uses historical data as a baseline and applies incremental changes, zero-based budgeting starts fresh every period. The key differences include:
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.
ZBB ties every dollar spent to the company’s strategic goals, ensuring that resources are allocated where they can generate the most value.
ZBB promotes transparency and accountability. Managers must justify their spending, which leads to more thoughtful and responsible budget proposals.
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.
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.
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.
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.
Implementing zero-based budgeting might seem daunting, but with a structured approach, it can deliver significant benefits. Here’s how to get started:
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.
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.
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.
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.
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.
Zero-based budgeting can be a powerful tool for aligning your financial planning with your organisation’s strategic objectives. While it requires more effort and time than traditional methods, the long-term benefits – cost efficiency, accountability, and flexibility – can make it a worthwhile investment. Whether you’re a large corporation or a growing business, adopting ZBB can help you optimise resources and drive sustainable growth.
