What is the difference between a base budget and a supplemental budget?

• A. A base budget covers special projects; supplemental covers staff salaries.
• B. A base budget maintains current service levels; supplemental covers proposed increases or decreases in spending for additional services.
• C. A base budget is only for capital expenditures; supplemental is for maintenance.
• D. A base budget is approved quarterly; supplemental annual.

Answer: (B)

Base budgeting focuses on sustaining the department’s current operations. It covers the ongoing, day-to-day expenses needed to maintain the present level of service—things like firefighter salaries, routine vehicle and equipment maintenance, utilities, and standard training. A supplemental budget is used to adjust that spending to pursue changes in services or add new programs. It represents proposed increases or decreases in spending beyond what the base budget allocates, to fund additional services or adjustments in response to new needs or opportunities.

For example, you’d rely on the base budget to keep operations at the current level. If you want to roll out a new fire prevention program or hire additional staff beyond what the base supports, you’d use a supplemental budget to request that extra funding.

The other options mix up what the base budget versus the supplemental budget typically covers: salaries and ongoing operations are not separate by base vs. supplemental in the way described; capital expenditures versus maintenance belong to different budgeting categories rather than the base/supplemental distinction; and whether budgets are approved quarterly or annually isn’t what defines the difference.
