In fiscal year 2024, the U.S. federal government recorded a deficit of $1.83 trillion—the third-largest in history outside the pandemic era. Although the government collected $4.9 trillion in revenue, it also spent a massive $6.8 trillion, driven by rising Social Security, health care, and net interest costs.

Here are the federal government’s three biggest categories of spending:

Social Security

Social Security is the largest single line item in the federal budget due to the combination of longer life expectancies and an aging population. The number of beneficiaries is growing quickly as baby boomers retire, even outpacing contributions from the current workforce.

Projections indicate that, without legislative changes, the Social Security Trust Fund may be depleted by the mid-2030s, potentially leading to benefit reductions of about 22% unless reforms are enacted.

Medicaid

Factors driving Medicaid spending include higher-than-anticipated enrollment and increased health care costs.

The program supports more than 80 million Americans, including low-income families, seniors, and individuals with disabilities. Recent legislative proposals aim to reduce federal Medicaid spending by up to $880 billion over the next decade, which could impact coverage for millions of beneficiaries.

Net interest on debt

The federal government’s interest payments on the national debt hit a record high in FY2024, nearly tripling from 2020 levels ($882 billion versus $345 billion). Interest payments now exceed the defense budget, and are expected to reach $1 trillion annually in the near future. This unprecedented growth is due to the combination of regular government overspending and higher interest rates (which were introduced to combat inflation).

Close behind: Medicare and Defense

Following the $882 billion for interest on the debt are Medicare and defense spending, both at $874 billion.
