To amend the Congressional Budget and Impoundment Control Act of 1974 to require any cost estimate for a bill or joint resolution prepared by the Congressional Budget Office to include the cost to each United States citizen for carrying out such measure, and for other purposes.

HR 9777 requires the Congressional Budget Office (CBO) to include per-citizen cost estimates in its budget analyses for all bills and resolutions. Specifically, the CBO must calculate and display the pro rata share of total federal spending and debt changes that would affect each U.S. citizen if the bill is enacted. This change applies to every bill requiring a CBO cost estimate, directly affecting lawmakers who rely on these analyses during the legislative process. The bill aims to provide clearer, more transparent data on the nationwide financial impact of proposed legislation.
