How Incremental Budgeting Works in Business Finance

Budgeting is the backbone of business finance. Without a clear plan, companies risk overspending, underfunding projects, or making poor strategic decisions. Many managers feel frustrated when complex budgeting systems take too much time or require endless approvals.

That’s where incremental budgeting comes in. Known for its simplicity, this method builds on last year’s numbers and adjusts them for the new financial period. In this article, you’ll learn how incremental budgeting works in business finance, when to use it, its advantages, drawbacks, and practical examples from 2025.

What Is Incremental Budgeting in Business Finance?

Incremental budgeting is a method of preparing budgets by adjusting the previous year’s figures. Instead of starting from scratch, businesses make small increases or reductions to reflect inflation, growth, or new projects.

Core Idea: Last year’s budget is the baseline. Add or subtract a percentage to set this year’s targets.

Example: A business allocated $200,000 for operations in 2024. For 2025, it applies a 5% increase for inflation, resulting in a $210,000 operations budget.

Step-by-Step Process of Incremental Budgeting

Here’s how incremental budgeting works inside most businesses:

1. Start with Last Year’s Budget
   Finance teams collect previous figures across departments.

2. Identify Adjustments
   Managers highlight inflation, staff changes, or new expenses.

3. Apply Incremental Changes
   Percentages are added or subtracted (e.g., +3% or –2%).

4. Review and Approval
   Department heads and finance directors verify fairness and accuracy.

5. Implementation and Monitoring
   Once approved, the new budget guides spending throughout the year.

This simple process makes incremental budgeting especially popular in large organizations.
