What is incremental budgeting?

Intermediate

Answer

Incremental budgeting sets the new budget by taking the previous period's figures and adjusting them for expected changes (e.g., inflation, volume). It's simple, quick, and stable, but perpetuates past inefficiencies, embeds slack, and doesn't challenge whether spending is still justified—contrasting with zero-based budgeting.
Last year costs 500 + 4% inflation = 520 budget.
Real-world example Each department's budget is last year's plus a few percent, without re-examining the underlying activities.
