The Peter G. Peterson Foundation (PGPF) released
its Chart Pack: The U.S. Budget in August 2025, offering a clear look at how
America raises and spends money. The federal government faces a long-term
imbalance: it spends much more than it collects, leading to persistent
deficits and rising debt.
Most of the budget—about 65%—goes to mandatory
spending on programs like Social Security, Medicare, and Medicaid. Social
Security costs $1.4 trillion in 2024, while Medicare and Medicaid together
cost $1.6 trillion. Discretionary spending—about 25% of the budget—covers
areas such as defense, education, and transportation. Defense dominates,
totaling $850 billion in 2024. The final share is interest on the national
debt, which reached $660 billion in 2024—more than federal Medicaid
spending—and could rise above $1 trillion a year by 2033.
The U.S. ran a $1.6 trillion deficit in 2024, equal
to 5.6% of GDP, and the CBO projects 6.1% in 2025. Public debt stood at $27
trillion in 2024 (99% of GDP) and is expected to climb to $45 trillion by 2034
(116% of GDP). By then, nearly 20% of federal revenues could go just to
interest payments, compared with 13% today.
Revenue is not keeping up. In 2024, federal revenues
equaled 17.6% of GDP, slightly below the long-term average of 18%. The bulk
came from individual income taxes ($2.2 trillion) and payroll taxes ($1.5
trillion). But as America’s population ages, the number of seniors will rise
nearly 50% from 2020 to 2040—costs for Social Security and Medicare will grow
sharply. Without reforms, the Social Security trust fund will be depleted by
2033, triggering an automatic 23% cut in benefits.
The takeaway from the Chart Pack is clear: spending
growth in entitlement programs and rising interest costs are outpacing
revenues, creating unsustainable deficits. Unless action is taken, debt will
surpass 116% of GDP within a decade, and interest will consume over $1
trillion annually, crowding out other national priorities.
