Explain the difference between incremental budgeting and zero-based budgeting; give an example of when each is appropriate.

Explain the difference between incremental budgeting and zero-based budgeting; give an example of when each is appropriate.

• A. Incremental budgeting uses existing budget with adjustments; appropriate in stable environments.
• B. Incremental budgeting requires starting from zero each period; appropriate for cost-cutting.
• C. Zero-based budgeting uses past budgets as a reference; appropriate for routine operations.
• D. Zero-based budgeting ignores past data entirely; appropriate for dynamic markets.

Answer: (A)

The main idea being tested is how budgeting starts from a base: either the previous period or from zero, and what that implies for when each method is most useful. Incremental budgeting builds the new budget by taking the previous period’s budget as the base and applying adjustments for expected changes, such as inflation, price increases, or known activity shifts. It’s simple and efficient, especially when operations are stable and costs don’t fluctuate drastically year to year. For example, a department might take last year’s budget and add a small percentage for anticipated wage rises and a known contract cost change. Zero-based budgeting, by contrast, starts from zero each period, and every expense must be justified anew. This approach forces a thorough review of all activities and can identify savings or eliminations that have become entrenched unnecessary, which is valuable when costs are uncertain, during major restructurings, or when there’s a strong cost-cutting push in a dynamic environment. An example is a company undertaking a strategic efficiency drive after a merger, where managers must justify every line item rather than assuming it’s needed because it existed previously. Thus, the description that aligns with incremental budgeting—using the existing budget with adjustments and being appropriate in stable environments—best captures the concept. The other statements misstate the methods (zero-based budgeting starting from zero, or using past budgets as the sole reference, or ignoring past data entirely).
