Elon Musk on national debt: what the evidence says · JRE #2223

What the evidence says 01 / RECORD

Musk stated that interest payments already equal 23% of all federal government revenue (income taxes, tariffs, and other receipts combined). By the standard federal-budget measure, net interest, which nets out interest income the government itself receives, net interest on the debt was about $881 billion in FY2024 against roughly $4.9 trillion in total federal revenue, a ratio of about 18%; FY2025 figures put it at roughly 18.5-19%, described by budget analysts as a record high surpassing the previous peak of 18.4% set in 1991. A broader gross-interest figure (total interest paid on outstanding Treasury securities before netting), which is not the measure typically cited by CBO or budget analysts as the debt-service burden, runs closer to 22-23% of revenue in the same period, which is likely the source of Musk's number. Under the standard net-interest framing used in most government and independent budget reporting, the 23% figure overstates the current burden by roughly 5 percentage points; interest costs are real, rising, and at a historic high relative to revenue, but not yet at 23% by the conventional metric.
