The United States is spending about $88 billion a month just to pay interest on its national debt, a burden that now stands near $39 trillion. New data from the Congressional Budget Office shows interest costs reached $529 billion in the first half of the current fiscal year, placing debt service on par with major federal priorities such as defense and education.
That level of borrowing pressure is becoming a growing policy problem because more debt now requires more money to maintain it. The CBO’s latest budget update indicates the government paid roughly $22 billion in interest each week, with higher long-term rates and a larger debt stock driving the increase.
Interest costs now rival top federal programs
The CBO said the near-$530 billion in interest payments covered the period from the start of the fiscal year through March. That figure is close to the same amount spent over that stretch on the Department of Defense and the Department of Education combined, underscoring how much of the federal budget is being absorbed by debt service.
Defense spending for the period totaled about $461 billion, while education spending reached $70 billion. Together, those outlays show how interest payments have become one of the federal government’s largest recurring costs.
Debt payments keep rising faster than relief
Interest expenses were also higher than in the same period a year earlier. The Treasury paid $497 billion in debt service in the first half of the prior fiscal year, meaning costs rose by $33 billion, or 7%, this year.
The CBO said the increase happened because the debt load was larger and long-term interest rates were higher. Lower short-term rates helped offset part of the rise, but not enough to stop the overall increase.
Federal finances still run deep in the red
The wider budget picture remains strained even with stronger revenue. The CBO reported receipts of $2.5 trillion in the first half of the fiscal year, up $223 billion from the same period a year earlier, while outlays climbed to $3.65 trillion from $3.57 trillion.
That left a deficit of $1.2 trillion for the first six months, an improvement of $140 billion from the previous year but still a pace that points to more than $2 trillion in borrowing over a full fiscal year. In March alone, the government borrowed $163 billion, slightly above the deficit recorded in the same month a year earlier.
What the numbers mean for policymakers
- Higher interest rates make existing debt more expensive to service.
- Larger deficits add more debt, which increases future interest costs.
- More federal revenue helps, but not enough to close the gap.
- Budget pressure limits room for defense, education, and other priorities.
Maya MacGuineas, president of the Committee for a Responsible Federal Budget, said lawmakers were still avoiding the core problem. She warned that Congress and the president need to put borrowing under control and reduce deficits from about 6% of GDP toward a more sustainable 3% of GDP.
The latest CBO update suggests the U.S. fiscal challenge is no longer only about how much the government spends, but how much it must pay simply to carry its debt. With interest costs climbing above $88 billion a month, the burden is now big enough to reshape debates over taxes, spending, and the long-term health of federal finances.
