The Congressional Budget Office (CBO)

The Congressional Budget Office (CBO) is Congress’s in-house referee for fiscal and economic analysis. It helps lawmakers understand how proposed legislation would impact spending, revenue, and the federal deficit — without taking sides.

1. What the CBO Does
The CBO provides nonpartisan budgetary and economic information to Congress.
  • Estimates how much proposed laws would cost or save the federal government.
  • Projects the economic and fiscal outlook over the next decade.
  • Analyzes the effects of federal policies on employment, inflation, and GDP.
The CBO doesn’t advocate policy — it quantifies consequences.
2. How the CBO Serves Congress
Congressional committees and members rely on CBO reports to guide debates and negotiations.
  • Budget Committees use CBO projections when setting fiscal targets.
  • Appropriations Committees consult cost estimates for new programs.
  • Individual members can request specific policy analyses.
The CBO’s data underpins nearly every serious budget conversation in Congress.
3. CBO “Scores” and Their Role
A CBO score is an estimate of how a bill would affect the federal deficit over time.
  • Scores can determine whether a bill qualifies under budget reconciliation rules.
  • They often shape public and political perception of a bill’s fiscal responsibility.
Lawmakers may support or oppose a bill largely based on its CBO score.
4. Independence and Accuracy
The CBO is deliberately insulated from partisan influence.
  • Its Director is appointed jointly by the Speaker of the House and the President pro tempore of the Senate.
  • Its staff includes economists, budget analysts, and statisticians — not political appointees.
The office’s credibility comes from decades of independence and transparency.
5. Why It Matters
The CBO helps Congress legislate responsibly — grounding debate in numbers instead of slogans.
In an era of divided politics, trusted math is one of democracy’s few shared languages.
