U.S. National Debt
What this page shows
The large number above is a live estimate, not an official figure: it starts from the U.S. Treasury's most recently published total and ticks upward (or downward) in your browser at the trailing 12-month average daily rate of change. The Treasury only publishes an authoritative total once per business day — that official number, with its as-of date, is always shown directly below the estimate.
Full detail on data sources, update cadence, and the exact math behind the live estimate is on the methodology & sources page. Want this number on your own site? Grab a widget.
National debt over time
Total public debt outstanding, from Treasury's Debt to the Penny dataset.
Debt held by the public vs. intragovernmental
The two components of total public debt outstanding. Area and bar views stack to the total; line view compares them directly.
Daily change
Day-over-day change in total public debt outstanding. Volatile by nature — auctions, redemptions, and debt-ceiling mechanics can swing it either way.
Debt per person over time
Total public debt outstanding, divided by U.S. resident population at each point in time (FRED series POPTHM, monthly).
