Zero-Based Budgeting

Zero-based budgeting (ZBB) is a method where all expenses must be justified for each new period, starting from a “zero base.” This approach requires managers to build their budgets from scratch and provide a rationale for every dollar requested, rather than simply adjusting the previous period's budget.

The core principle of ZBB is to scrutinize all expenses, linking them directly to organizational goals and activities. This process encourages a more strategic approach to cost allocation and resource management. It forces departments to prioritize essential operations and identify inefficiencies or outdated spending that might otherwise be carried over in an annual budgeting cycle.

While ZBB can be more time-consuming than traditional budgeting, it provides greater visibility into spending and can lead to significant cost savings. It is often employed during periods of economic pressure, restructuring, or when a company seeks to fundamentally realign its operational expenses with strategic priorities.
