For the first time in American history, Washington spent more than $1 trillion in a single year just to pay interest on the national debt. Not to build a road, not to fund a single soldier, not to send a Social Security check. Just to cover the cost of past borrowing. That bill now tops what we spend on national defense, and it should be the loudest alarm in Washington this fall.
The final Treasury numbers for fiscal year 2026 are in, and they tell a story fiscal conservatives have warned about for decades. Here is what happened, why it matters to your wallet, and what a serious fix looks like.
Interest on the National Debt Hits $1.05 Trillion
According to the Treasury Department’s final Monthly Treasury Statement for fiscal 2026, the federal government paid $1.052 trillion in net interest in the year that ended September 30.
That makes interest the third-largest line in the entire federal budget. Only Social Security ($1.667 trillion) and Medicare ($1.073 trillion) cost more. National defense came in behind interest, at under $970 billion.
Think about that ranking for a moment. In other words, interest on the national debt now costs more than defending the country.
The Deficit Hit Nearly $2 Trillion
The full-year deficit landed at $1.992 trillion, a 12% jump from $1.775 trillion in fiscal 2025. As Yahoo Finance reported, that is roughly 6% of the entire U.S. economy.
That is the kind of deficit America used to run only during wars and deep recessions. In 2026 we had neither excuse on that scale, and we ran it anyway.
The Debt Crossed $40 Trillion
Gross national debt passed $40 trillion in August. Treasury’s most recent “Debt to the Penny” reading put it above $40.3 trillion. Every one of those dollars carries an interest cost, and that cost keeps rising.
Why Interest on the National Debt Is Exploding
Two forces are driving interest on the national debt higher, and unfortunately they feed each other.
First, the pile is bigger. Washington keeps borrowing trillions every year, so there is simply more debt to pay interest on.
Second, the rate is higher. The average interest rate on federal debt has climbed to about 3.53%, more than double the roughly 1.6% the government paid in 2021. As old, cheap debt matures, Treasury has to refinance it at today’s higher rates.
The Committee for a Responsible Federal Budget estimates net interest hit about 3.3% of GDP this year, a record, as Axios noted. Economists call the result a debt spiral: more debt means more interest, more interest means bigger deficits, and bigger deficits mean more debt.
This Is a Spending Problem, Not a Revenue Problem
Of course, you will hear the usual chorus that the answer is higher taxes. However, the numbers do not support it.
In fiscal 2026, federal revenue rose about 3% to $5.403 trillion. Spending rose about 6% to $7.396 trillion. Washington’s income grew. Its appetite simply grew twice as fast.
The Congressional Budget Office’s 2026–2036 Budget and Economic Outlook makes the same point over the long run. CBO projects revenue at 17.5% of GDP this year, slightly above the 50-year average of 17.3%. Outlays, meanwhile, sit at 23.3% of GDP, and CBO expects them to climb to 24.4% by 2036.
When revenue is at or above its historical norm and the deficit is still near $2 trillion, the problem is not that Americans are undertaxed. The problem is that Washington spends too much.
Both Parties Own This
Fiscal conservatism means being honest, including about our own side. CBO estimates that the 2025 reconciliation law added about $4.7 trillion to projected deficits over the decade, while higher tariffs reduced them by about $3.0 trillion.
Tax relief is good policy. Letting families and businesses keep more of what they earn grows the economy. But tax cuts without spending restraint just move the bill onto the national credit card, and the interest on that card is now over a trillion dollars a year.
What It Means for Your Family
Interest on the national debt is not some abstract number. It hits ordinary Americans in at least three ways.
- Crowding out priorities: Every dollar spent on interest is a dollar not available for defense, border security, or tax relief.
- Higher borrowing costs: Heavy federal borrowing competes with families and businesses for capital, which can push up rates on mortgages, car loans, and small-business credit.
- A bill for our kids: CBO projects debt held by the public will rise from 101% of GDP this year to 120% by 2036, past the previous record of 106% set in 1946, right after World War II.
What a Serious Fix Looks Like
Fortunately, this is a choice, not fate. A credible plan does not require gutting the safety net or raising taxes on working families. It requires discipline.
- Cap the growth of federal spending below the growth of the economy, so the debt shrinks relative to GDP over time.
- Attach real reforms to the debt ceiling. According to CNN, the U.S. will likely hit the limit again next year. That is leverage, so Congress should use it to win enforceable spending caps.
- Protect older Americans by reforming, not ignoring, entitlements. Social Security and Medicare are the two largest outlays. Pretending they can grow on autopilot forever is how you guarantee painful cuts later.
- Pair pro-growth tax policy with offsets so tax relief strengthens the economy without swelling the deficit.
- Audit and claw back waste across federal agencies before asking taxpayers for a single dollar more.

- Gross national debt topped $40 trillion in August and now exceeds $40.3 trillion.

Frequently Asked Questions
How much did the U.S. pay in interest on the national debt in 2026?
The federal government paid $1.052 trillion in net interest in fiscal year 2026, according to Treasury’s final Monthly Treasury Statement. It was the first time net interest topped $1 trillion.
Is interest on the debt now bigger than defense spending?
Yes. In fiscal 2026, net interest exceeded national defense spending, making it the third-largest federal outlay after Social Security and Medicare.
Why is interest on the national debt rising so fast?
The debt is larger, and interest rates are higher. The average rate on federal debt has risen to about 3.53% from roughly 1.6% in 2021, so Treasury now refinances maturing debt at a much higher cost.
