The US Congress just learned the Iran war carries a $37.5 billion price tag on paper — but the real bill Americans may pay could be far higher and stretch for years.
Story Snapshot
- Pete Hegseth told senators the Iran war’s cost is now estimated at $37.5 billion.
- The figure mixes money already spent with costs projected through September 30.
- Earlier Pentagon updates put the running total at $25 billion, then $29 billion, in just weeks.
- Outside analysts say the true “cost of war” could eventually land in the hundreds of billions or more.
Hegseth’s $37.5 Billion Number Lands With A Jolt
Defense Secretary Pete Hegseth sat before the Senate Appropriations Committee and gave the clearest number so far: the war with Iran will cost an estimated $37.5 billion by the end of the current fiscal year. He framed that figure as the administration’s latest internal tally when pressed by Senator Dick Durbin.
The number was not a casual quote. It arrived in the middle of a heated fight over President Trump’s push for tens of billions more in defense funding tied to the Iran conflict.

Hegseth explained that the $37.5 billion does not only cover what has already gone out the door. It also includes “additional operations and maintenance, military pay and other” costs the Pentagon expects to incur through September 30.
That matters for taxpayers who assume a war price tag is a simple “meter reading” of cash already burned. In reality, Hegseth’s figure is part cost report, part forecast, built around how the Pentagon plans and funds deployment, munitions, and personnel.
The Pentagon’s Running Tab Keeps Climbing
The $37.5 billion estimate did not appear out of thin air. It grew out of a series of earlier Pentagon updates that show just how fast war spending can ramp up.
In late April, Pentagon financial chief Jules Hurst told lawmakers the war had cost about $25 billion, heavily driven by munitions, operations, maintenance, and equipment replacement.
Only weeks later, Hurst returned and said the figure was already closer to $29 billion, thanks to added repair and replacement costs and the ongoing price of keeping troops and hardware in theater.
Those numbers came on the heels of even earlier briefings that stunned many in Congress. Pentagon officials privately told lawmakers the first six days of the war had already cost $11.3 billion in “unbudgeted” expenses.
Analysts at the Center for Strategic and International Studies walked through the munitions alone and concluded the opening twelve days likely ran to about $16.5 billion. That early burn rate set the tone: this was a war that could swallow tens of billions long before any clear endgame came into view.
What The $37.5 Billion Leaves Out
Hegseth’s testimony made clear his $37.5 billion figure covers “certain aspects” of the war, mainly operations, maintenance, and pay. Other reporting says damage to U.S. bases and broader military construction needs are not fully counted in that current estimate. That gap matters because the war has included heavy missile and drone strikes on U.S. facilities in the region.
Rebuilding hardened structures, repairing airfields, and replacing damaged support equipment can add major costs that arrive months or years after the shooting starts.
The administration’s budget request shows how narrow that $37.5 billion really is. Alongside that price tag, the White House is asking for about $67 billion in extra defense funds tied to the Iran conflict, within a supplemental package nearing $90 billion. That larger ask aims to both cover ongoing operations and restock weapons stores drained by high-tempo combat.
When Americans hear “war cost,” they often imagine one number. In practice, there is the current operations bill, the replenishment bill, and a long tail of repair and readiness bills that may not be fully visible yet.
Outside Estimates Point Much Higher
Critics and independent experts are already arguing Hegseth’s number is far too low. Some outside analysts who track war spending say the full price tag, once repairs, replacements, and other indirect costs are counted, is easily in the $80 to $100 billion range for the Iran war’s first phase. Others go even further.
One Harvard policy scholar who examined daily operational costs and hidden logistics estimated the war could eventually run to one trillion dollars over the next decade, depending on how long it drags on and how deeply it disrupts the region.
These higher estimates follow a familiar pattern in U.S. war accounting. After 9/11, official budget numbers for Iraq and Afghanistan sat around $1.5 to $1.9 trillion in direct appropriations, while outside researchers who added veterans’ care, interest on borrowed money, and broader economic losses reached $4 to $6 trillion and beyond.
A separate “cost of war” project has tallied more than $8 trillion spent on U.S. wars since 2001, rising to double-digit trillions when future obligations are included. When people say “what did the war cost,” they are often talking about very different ledgers.
The Real Fight: Transparency And Definitions
This clash over the Iran war’s price tag is not just about math. It is about what politicians choose to count. Hegseth is speaking in the language of near-term Pentagon budgeting: operations, maintenance, pay, and munitions within the current fiscal year.
Journalists and academics pressing higher figures are stretching the lens to include long-term base repairs, replacement of lost aircraft, and downstream effects on fuel prices and global trade. Both approaches tell part of the story, but only one is formally tracked in the Pentagon’s day-to-day cost reports.
From this perspective, Americans deserve honest, apples-to-apples numbers. War is sometimes necessary. But if the Pentagon tells Congress “$37.5 billion,” that number should be backed by a clear breakdown of what is in and what is out, not buried in classified worksheets. Anonymous leaks that hint at much higher costs without documents are no better.
The war in Iran has already shown that bills can leap from $11.3 billion in a week to $37.5 billion in a matter of months. Voters footing that bill should not need a Ph.D. in defense accounting to understand the tab.
