Understanding Zero-Based Budgeting (ZBB): A Practical Guide for Beginners

Zero-Based Budgeting (ZBB) is gaining renewed attention in 2025 as organizations seek more strategic and cost-effective planning methods by requiring all expenses to be justified from scratch. While ZBB offers benefits such as improved cost efficiency, better resource allocation, and increased transparency, it also presents challenges like time-intensive processes and resistance to change. Kepion simplifies ZBB implementation with intuitive modeling, real-time insights, and seamless collaboration, making it easier for businesses to embrace this budgeting approach without traditional complexities.

With the unprecedented change in the world today, and with the wheels of business always turning, organizations are being asked to justify every dollar they plan to spend. That’s where Zero-Based Budgeting (ZBB) comes in — a method that’s making a comeback in 2025 for organizations needing to be more strategic and cost-effective. 

Unlike traditional budgeting, which adjusts past budgets incrementally, ZBB requires every expense to earn its place — starting from Zero ensuring that each dollar is spent effectively. The goal of a zero-based budget is that your income minus your expenditures equals zero by the end of the month.

But is Zero-Based Budgeting the right fit for your organization this year? In this blog, we’ll explore its advantages and challenges, discuss how it aligns with modern planning strategies, and how you can choose the right process to help you weather the unpredictable socio-economic storms brewing…

What Is Zero-Based Budgeting?

Zero-Based Budgeting is a budgeting concept and system where all planned expenses must be justified for each new planning cycle. The core principle of this approach is starting from zero, meaning that the budget is developed from scratch each cycle rather than simply using the previous year’s budget with minor tweaks. Zero-based budgeting requires a detailed justification of all expenditures, both recurring and new, ensuring that every cost is necessary and aligned with current priorities and desired outcomes. The processes involved in zero-based budgeting differ significantly from traditional budgeting methods, as each expense must be reviewed and approved individually. This concept has both advantages and disadvantages, which will be discussed in the article.

Benefits of Zero-Based Budgeting

1. Improved Cost Efficiency

With ZBB, you eliminate unnecessary or wasteful costs by requiring teams to tie every dollar to a business outcome. This approach ensures that funds are allocated based on real business priorities today rather than just historical spending patterns or what got approved last year.

Teams must calculate and identify all expenditures to ensure cost efficiency, justifying each expense and optimizing resource allocation.

2. Better Resource Allocation

By starting from zero, with ZBB, organizations must decide how to allocate resources from scratch, ensuring every dollar is assigned based on current needs and priorities. Deciding where to allocate resources is a key part of the zero-based budgeting process, as it requires careful evaluation and conscious choices to maximize impact. By allocating funds more appropriately and dynamically, businesses can respond to market shifts more effectively.

3. Enhanced Strategic Planning

Strategic planning involves envisioning the future and recalling past experiences to inform decisions. Zero-Based Budgeting gives you the opportunity to align every line of your financial plan with your long-term business goals. Rather than simply maintaining the status quo, you take a proactive forward-looking approach — not a backward-looking, to investment and cost control.

4. Increased Transparency

By breaking down budgets to the smallest expense levels, with ZBB you get full visibility into where and how funds are being spent across departments, helping teams become more aware of their spending. This transparency allows organizations to realize where funds can be better utilized. That visibility fosters accountability and empowers smarter, more confident decisions at every level.

Challenges of Zero-Based Budgeting

While ZBB offers compelling benefits, it also comes with challenges that organizations should consider. Among the disadvantages are its time-consuming nature, resource intensity, and a potential bias toward short-term gains, which may lead to overlooking long-term investments. Additionally, there is a risk involved in organizational and strategic planning, as improper goal setting or resource allocation can impact outcomes and increase the likelihood of negative consequences. Zero-based budgeting also involves distinguishing between planned, non-monthly expenditures and a general contingency fund.

1. Time-Intensive Process

Unlike traditional budgeting, which allows for incremental adjustments, ZBB requires detailed analysis and justification for every expense. Without automation or the right tools, this can become a burden on FP&A teams and everyone involved in the planning process. The remaining amount of time and effort required can be significant, and all team members must contribute to the process.

2. Complexity in Implementation

For large companies with many departments and cost centers, the development and implementation of ZBB can be particularly challenging.

3. Resistance to Change

Shifting to ZBB means changing how teams think about planning. Some employees and leaders accustomed to traditional budgeting may resist. Overcoming this requires strong leadership and clear, proactive communication about the benefits of the new approach.

Is Zero-Based Budgeting Right for You?

ZBB isn’t one-size-fits-all — but if your organization needs to optimize spend, increase visibility, and plan more intentionally, it may be exactly the shift you need in 2025. Before deciding, it’s important to understand your financial situation, including all sources of income. Zero-based budgeting helps you manage your money by allocating funds to specific departments, cost centers, or projects for operating expenses, capital expenditures, debt service, and strategic investments.

It requires you to allocate all company revenue to necessary operating costs (needs), growth initiatives/R&D (wants), retained earnings/cash reserves (savings), and loan/bond payments (debt). You should pay and save proactively, and track expenditures in each certain category. Any remaining amount can be allocated to savings or carried over to the next month’s budget. Using zero-based budgeting can help you achieve financial stability. And with the right planning solution, the transition doesn’t have to be painful.

With Kepion, you can take a fresh approach to budgeting and planning — without starting from scratch on your own. You get flexible models, collaborative and integrated planning, for real-time insights to make Zero-Based Budgeting work for your business.
