The United States federal budget consists of mandatory expenditures (which includes Medicare and Social Security), discretionary spending for defense, Cabinet departments (e.g., Justice Department) and agencies (e.g., Securities & Exchange Commission), and interest payments on debt. This is currently over half of U.S. government spending, the remainder coming from state and local governments.

Major categories of FY 2017 spending included: Healthcare such as Medicare and Medicaid ($1,077B or 27% of spending), Social Security ($939B or 24%), non-defense discretionary spending used to run federal Departments and Agencies ($610B or 15%), Defense Department ($590B or 15%), and interest ($263B or 7%). Expenditures are classified as "mandatory", with payments required by specific laws to those meeting eligibility criteria (e.g., Social Security and Medicare), or "discretionary", with payment amounts renewed annually as part of the budget process, such as defense. Around two thirds of federal spending is for "mandatory" programs. CBO projects that mandatory program spending and interest costs will rise relative to GDP over the 2016–2026 period, while defense and other discretionary spending will decline relative to GDP. (en)
