What Is the US Debt Clock? Live U.S. National Debt Tracker
The US Debt Clock tracks the United States national debt using official U.S. Treasury data, then projects the latest observed change so you can watch the debt move live. The current total is about 39.69T, or roughly $118,481 per citizen.
Latest source date: 2026-03-19. The display is recalibrated whenever a new official Treasury record is available.
How The Clock Is Calculated
The official starting point is the Treasury's Debt to the Penny dataset. Between records, the clock applies the latest observed rate of change so the number updates continuously. That makes the page useful for live monitoring while preserving a clear connection to government source data.
