Mandatory Spending

How It Works

Mandatory spending (also called "direct spending") accounts for roughly 63% of federal outlays and is growing steadily as the population ages. The major mandatory programs in FY2023 were: Social Security ($1.35 trillion, covering 67 million retirees and disabled workers), Medicare ($1.0 trillion gross, $839 billion net of premiums, serving 65 million beneficiaries), Medicaid and CHIP ($616 billion federal share for 94 million enrollees), income security programs including SNAP, SSI, unemployment, and refundable tax credits (~$540 billion), federal civilian and military retirement (~$200 billion), and veterans benefits (~$160 billion). On top of program spending, net interest on the national debt surged to roughly $660 billion in FY2023 and is projected to exceed defense spending by FY2025, the fastest-growing line item in the entire budget as rising interest rates meet a $34 trillion debt stock. Unlike discretionary spending, mandatory programs do not require annual appropriations, eligibility rules and benefit formulas in the authorizing statutes (Social Security Act, Medicare and Medicaid statutes, Internal Revenue Code) automatically dictate payments. Changing mandatory spending requires Congress to amend the underlying authorizing law, a process called reconciliation that bypasses the Senate filibuster but can only be used once per fiscal year under the Congressional Budget Act of 1974. Mandatory spending is largely invisible on USASpending.gov contract-level views because most of it flows as direct payments to individuals rather than contracts or grants; however, the administration of mandatory programs (Medicare contractor processing through MACs, Social Security IT systems, Medicaid management information systems) does generate substantial discretionary contract spending. CMS alone obligates over $20 billion annually in contracts to operate Medicare, the Federal Marketplace, and state Medicaid oversight.
