Zero-base budgeting

3 key takeaways

• Zero base budgeting requires justifying all expenses from scratch each period.
• It promotes efficient resource allocation by linking expenses to current needs and objectives.
• ZBB can be more time-consuming compared to traditional budgeting methods.

What is zero base budgeting?

Zero base budgeting (ZBB) is a method of budgeting in which all expenses must be justified for each new period. Unlike traditional budgeting, which often involves making incremental changes to the previous period’s budget, ZBB starts from a “zero base.” This means that every function within an organization is analyzed for its needs and costs, and budgets are built around what is needed for the upcoming period, regardless of past expenditures.

The primary goal of ZBB is to align expenditures with organizational goals and priorities. This approach encourages managers to rethink their operations and find more efficient and cost-effective ways to allocate resources.

How does zero base budgeting work?

Zero base budgeting involves several steps:

1. Identify decision units: The organization is divided into decision units, which are segments, departments, or cost centers that are responsible for certain functions or activities.
2. Evaluate activities: Each decision unit evaluates its activities and expenditures from the ground up, justifying each expense in terms of its necessity and alignment with organizational goals.
3. Rank activities: The activities are then ranked based on their importance and contribution to the organization’s objectives. This helps prioritize funding for essential and high-impact activities.
4. Allocate resources: Resources are allocated based on the rankings, ensuring that the most critical activities receive the necessary funding.

Example

Consider a marketing department using ZBB. Instead of basing the new budget on last year’s spending, the department starts from zero and justifies each expense, such as advertising campaigns, market research, and promotional events, based on their expected contribution to the company’s goals. Only the activities that align with these goals and demonstrate value are funded.

Advantages and disadvantages of zero base budgeting

Advantages

• Efficient resource allocation: By starting from zero, ZBB ensures that resources are allocated to activities that are most aligned with the organization’s current goals and priorities.
• Cost control: ZBB can help identify and eliminate unnecessary or redundant expenditures, leading to better cost management.
• Encourages strategic thinking: Managers are forced to justify their budgets and think critically about their operations and spending.

Disadvantages

• Time-consuming: The process of evaluating and justifying each expense can be more time-intensive than traditional budgeting methods.
• Complexity: Implementing ZBB requires thorough understanding and meticulous planning, which can be challenging for large organizations.
• Resistance to change: Employees and managers accustomed to traditional budgeting may resist the shift to ZBB due to its demanding nature.

Applications of zero base budgeting

Zero base budgeting is used in various sectors to enhance financial efficiency and strategic planning:

• Public sector: Governments and public institutions use ZBB to ensure taxpayer money is spent effectively, aligning expenditures with policy goals.
• Corporations: Businesses adopt ZBB to improve cost control and ensure investments are directed towards activities that drive growth and profitability.
• Nonprofits: Nonprofit organizations use ZBB to justify funding for projects and programs, ensuring resources are used effectively to achieve their mission.
