What is the main goal of using zero-based budgeting?

Using zero-based budgeting primarily focuses on aligning all expenses with strategic goals. This budgeting method requires each department to justify its budget from scratch, or "zero-based," for every new period. Essentially, it compels managers to analyze their needs and costs carefully, ensuring that every dollar spent is necessary and contributes directly to the organization's objectives. By doing so, it fosters a clear understanding of how resources are allocated in pursuit of specific goals, rather than simply continuing past spending patterns.

The emphasis is on evaluating each expense based on performance and outcomes, rather than historical data, which can lead to misallocation of resources. This approach is particularly beneficial in dynamic environments where priorities may shift, and it enables organizations to focus their budgets on activities that drive value and advance strategic initiatives.
