US National Debt Growth
The gross federal debt subject to the statutory limit includes debt held by the public (Treasury securities owned by investors, mutual funds, foreign governments, and the Fed) plus intragovernmental holdings (e.g. trust funds). It grows when outlays exceed receipts and when existing debt is rolled over at new interest rates. In fiscal year 2025 debt held by the public rose by $2.0 trillion, reaching $30.3 trillion, or an estimated 98% of GDP. The counter uses that $2.0 trillion increase. Note that it is not the same thing as the deficit, which was $1.8 trillion in the same year — the two differ because of intragovernmental holdings, premiums and discounts on issuance, and timing. Actual cash deficits and Treasury auction calendars vary month to month; one-time fiscal packages and economic slowdowns can widen or narrow the gap quickly.

Reading US National Debt Growth as a spending counter
MoneyPerSecond Editorial·Data last reviewed: August 26, 2026
The debt limit debates in Congress concern *statutory authorization to borrow*, not the same thing as deciding each year's deficit in appropriations bills. Treasury still accrues interest on outstanding securities when politicians negotiate a limit increase; our counter visualizes accumulation pace, not legislative drama timing.
Interest expense rose sharply when the Fed hiked rates: rolling over maturing Treasuries at higher coupons increases annual outlays even if primary deficits stabilize. That feedback loop is why "debt growth" and "interest on debt" are linked but not identical rows in CBO tables.
Foreign official holdings (Japan, China, UK) and the Federal Reserve's System Open Market Account change who receives coupon cash flows, but gross debt outstanding still rises when deficits continue. Treasury Fiscal Data's "Debt to the Penny" gives the stock level; this counter shows a flow rate.
Intragovernmental debt (Social Security trust fund IOUs) is money one part of government owes another—it still counts in gross debt subject to limit but differs economically from debt held by the public. Our teaching estimate blends both unless we note otherwise in methodology.

The counter starts from January 1st of the current year and accumulates at a rate of $63,419.58 every second, based on US National Debt Growth's estimated annual figure of $2T.
Methodology
We approximate a single annual increment to match the site's linear counter. CBO baseline deficits and Treasury "debt to the penny" releases inform the magnitude, but we do not replay daily Treasury cash operations. The per-second rate spreads the chosen annual figure evenly; it is not a live feed from Treasury servers.

Frequently Asked Questions
How fast is the US national debt growing per second?
Debt held by the public grew by $2.0 trillion in fiscal year 2025, which works out to roughly $63,400 per second, or about $5.5 billion per day, spread evenly. For comparison, the FY2025 deficit was $1.8 trillion — $7.0 trillion of spending against $5.2 trillion of receipts.
What is the current US national debt?
Debt held by the public stood at $30.3 trillion at the end of fiscal year 2025. Gross federal debt, which also counts intragovernmental holdings, is higher. Treasury publishes the level daily as "Debt to the Penny" — that is the number to check for today's figure, since this page shows a rate of growth rather than a level.
Who owns US government debt?
A large share is held by private and foreign investors in marketable Treasury securities; another portion sits in government accounts. The Federal Reserve held significant amounts during quantitative easing periods, affecting interest flows to the private sector.
Is growing debt the same as the government "printing money"?
Not exactly. New debt is usually issued via Treasury auctions; the Fed can buy bonds as part of monetary policy, which affects reserves and rates, but fiscal deficits and central-bank operations are distinct mechanisms with different institutional rules.
