How to read this number

Spending and debt answer different questions. This page shows spending within one federal budget function. The national debt is the accumulated outstanding balance of federal borrowing, not a sum of these category counters.

Source, calculation & original data

Source: U.S. Treasury, Monthly Treasury Statement, Table 9. Retrieved 2026-10-26. Reported total: $39,876,759,074.

Rate = reported amount ÷ 31,536,000 seconds in the reporting period. Estimated ranges apply this historical average to elapsed seconds since midnight today, Monday, the first of the month, or January 1 (UTC). These are modeled totals, not measured weekly, monthly or calendar-year outlays. The reported-period view shows the original published total. Estimates stop 45 days after the reporting period ends. Negative net outlays remain static.

Funds approved by law and actual outlays differ in timing and scope. This page does not claim to show a new congressional appropriation.
