US National Debt Crosses $40 Trillion, With the Latest Trillion Added in Just 154 Days

The United States national debt has crossed $40 trillion, a milestone reached with the Trump administration adding the latest $1 trillion in just 154 days, according to an analysis by Mike Maharrey published by GoldSeek.

As of August 18, the national debt stood at $40,047,425,768,420.22. That headline number is gross federal debt, which counts Treasury securities held by the public — including domestic and foreign investors and the Federal Reserve — as well as intragovernmental holdings such as the Social Security trust funds.

Putting a figure of that size into perspective requires several yardsticks, beginning with the daily pace of borrowing. Over the last 22 weeks, the federal government has added roughly $6.5 billion in new debt every single day. If the U.S. government folded the debt into a single 30-year bond at 5 percent, it would need to accumulate roughly $9.13 billion per day to pay off the bond at term.

According to the National Debt Clock, every U.S. citizen would need to write a check for $116,487 to pay off the debt. Because many Americans pay no federal income taxes, the bill would come to $360,794 each if only taxpayers footed it.

The debt-to-GDP ratio stands at 122.71 percent — territory the country has not occupied since the World War II era, when borrowing surged to finance the war effort, and from which the ratio declined for decades afterward as economic growth outpaced new borrowing. At $30 trillion, the national debt is already bigger than the combined annual GDP of China, Germany, India, Japan, and the UK.

Debt Accumulation by Administration

When President Trump took office in 2024, the debt stood at $36.2 trillion. In other words, he has added around $3.8 trillion to the debt so far during his second term.

When Biden took up residence at 1600 Pennsylvania Avenue, the national debt stood at just under $27.8 trillion. Debt added during Biden's time in office totaled around $8.4 trillion — a little more than the $7.8 trillion piled on during Trump's first term. Since the beginning of Trump's first term, the two administrations together have roughly doubled the national debt.

By comparison, former President Barack Obama was pilloried as a big spender because he was the first president to generate $1 trillion deficits, a feat he managed three times during the Great Recession.

An Accelerating Timeline

The accelerating pace of debt accumulation can be seen in how many days it took to add each new $1 trillion. The national debt hit $34 trillion in January 2024. Ten months later, it eclipsed $35 trillion in November 2024. It then took 188 days for the debt to grow from $35 trillion to $36 trillion, and another 265 days to reach $37 trillion.

That apparent slowdown reflected the debt ceiling rather than restraint in borrowing. The debt ceiling is a statutory cap Congress sets on total federal borrowing; reaching it does not undo spending lawmakers have already authorized, but it does bar the Treasury from issuing the new debt needed to pay those bills. The federal government bumped up against the debt ceiling on January 1, 2025, and could not borrow any money until the enactment of the "Big Beautiful Bill," which raised the ceiling by $5 trillion as of July 1. At that time, the national debt stood at $36.2 trillion, putting the new ceiling at roughly $41.2 trillion — a little more than $1 trillion above the current $40 trillion total, and the next fixed checkpoint in the borrowing debate.

It then took less than two months for the federal government to borrow more than $800 billion, pushing the debt over $37 trillion. Barely two months later, the total stood at $38 trillion. The government increased the debt by another trillion in 150 days, and the debt crossed $40 trillion just 154 days after that.

Rising Interest Costs

All this debt is expensive. July interest payments pushed total interest expense to $1.17 trillion through the first 10 months of fiscal 2026 — the federal fiscal year runs October through September, which is why the ten-month tally ends in July — up 15.5 percent compared with the same period in fiscal 2025. Interest on the national debt cost $1.2 trillion in fiscal 2025, up 7.3 percent over 2024. At that scale, interest ranks among the largest single line items in the federal budget, in the same range as annual defense spending.

Maharrey points to those interest costs as the reason he believes the Federal Reserve will not be able to hold interest rates higher for longer, and suggests they are almost certainly why the Treasury Department has put its thumb on the bond market with increased buybacks — a reference to the department's regular repurchases of older, off-the-run securities, a liquidity-management practice revived in 2024.

When boiled down, he argues, the federal government is functionally insolvent, and money printing is the only thing keeping the ship afloat.

Earlier this year, Forbes argued, "The reckoning, long deferred, is becoming impossible to ignore."

And yet, in Maharrey's telling, the mainstream continues to ignore the problem. The Treasury released the data to the sound of crickets, and when milestones like this are reached, a few people sit up and take notice while most shrug and carry on as if everything were fine.

"Ladies and gentlemen, everything is not fine," he writes.
