War Bill Skyrockets — Where Did It Go?

Cash placed inside a military uniform pocket — WAR BILL SKYROCKETS

Lawmakers just learned the Iran war’s official price tag is $37.5 billion, and that number may only cover part of the bill.

Story Snapshot

Pete Hegseth told senators the Iran war will cost an estimated $37.5 billion this fiscal year.
The figure mixes what has already been spent with costs the Pentagon expects through September 30.
Earlier Pentagon updates put the running total closer to $25 billion, then $29 billion, showing a fast climb.
Outside analysts and some officials say the real cost could be far higher once repairs and long-term bills are counted.

Hegseth’s $37.5 billion number and what it really covers

Defense Secretary Pete Hegseth went before the Senate Appropriations Committee and gave the most detailed public estimate so far for the U.S. war against Iran.

When Senator Dick Durbin pressed him for a number, Hegseth replied, “Senator, the estimate we have as of today is 37.5 billion.” He said that figure comes from Pentagon accounting and represents the current best estimate, not something he pulled out of thin air at the hearing.

Hegseth also explained that the $37.5 billion is not limited to past spending. It includes some costs that will be incurred through the end of the current fiscal year on September 30, like military pay, operations and maintenance, and other anticipated expenses.

That makes the number more of a “this year’s war bill” than a simple “amount spent so far,” even though headlines often present it as a running total. For taxpayers, that nuance matters because it blends yesterday’s checks with tomorrow’s promises.

How the official price tag grew from $25 billion to $37.5 billion

The $37.5 billion estimate did not appear out of nowhere. In late April, Pentagon officials told Congress the war had cost about $25 billion to that point.

By mid-May, the Pentagon’s acting comptroller, Jules Hurst, said the updated estimate was closer to $29 billion, citing new repair and replacement costs and general operational spending to keep forces in theater.

Hegseth’s July testimony framed the $37.5 billion as the next step in that internal review, not a break from earlier numbers.

Those jumps reflect how war costs move as damage reports roll in and units stay deployed longer than planners first assumed. Ammunition, fuel, flight hours, hazard pay, and worn-out gear all add up.

That pattern matches what budget studies have found in earlier conflicts: direct war appropriations tend to rise steadily as missions drag on and accounting catches up. For anyone who remembers how early “short war” promises in Iraq turned into trillion-dollar totals over time, this should sound familiar.

The missing pieces that could push the true cost much higher

Anonymous officials and outside experts say Hegseth’s number leaves out big categories of spending. Reporting by CBS News and others notes that the $37.5 billion estimate may exclude major military construction to repair damaged U.S. bases hit in Iranian missile attacks.

Repairs for runways, hangars, fuel farms, and hardened shelters are not cheap, and historically they often show up in separate military construction line items rather than the core operations tally.

Some intelligence officials and analysts told reporters they believe the total cost of the Iran war is already between $80 billion and $100 billion. Their higher figures fold in base rebuilding, replacement of destroyed aircraft and missiles, logistics, and other indirect costs that do not always appear in early Pentagon briefings.

One Harvard scholar, looking at day-by-day spending patterns, has argued that short-term costs of about $2 billion a day are only the “tip of the iceberg” and that the war could reach a trillion dollars over a decade when long-term care for veterans, interest on borrowing, and wider economic effects are included.

Why honest people disagree on the ‘cost of war’

War cost debates almost always turn on what, exactly, gets counted. Defense officials tend to quote budget authority and near-term operational totals, because that is what Congress must vote on and what the Department of Defense tracks in its ledgers.

Outside economists and watchdog groups make much larger estimates that add in long-term health care for wounded troops, equipment replacement, interest payments on war debt, and even ripple effects like higher fuel prices.

Studies of post-9/11 wars show this gap clearly. Official U.S. budget figures for Iraq, Afghanistan, and related operations have been in the range of $1.6 trillion to about $2 trillion.

Independent projects, like the Costs of War initiative at Brown University, put total economic costs around $4 trillion to $6 trillion and up, depending on how far into the future they project.

When someone says the Iran war has cost $37.5 billion, and another says it could top $1 trillion, they are using very different yardsticks.

Budget politics, conservative values, and the push for more funding

Hegseth’s testimony did more than reveal a number. It tied the $37.5 billion estimate directly to the Trump administration’s request for a $67 billion supplemental defense package related to the Iran war, and an overall defense budget near $1.5 trillion.

He warned senators that without extra funds, the military faces “critical shortfalls” in munitions and readiness, arguing that replenishment is as important as paying for current operations.

From this view, two questions stand out. First, if the war has already run into tens of billions in direct costs, and the Pentagon still cannot clearly show taxpayers which bills are included in the $37.5 billion and which are parked elsewhere, transparency is lacking.

Second, if outside estimates that include repairs, replacement hardware, and long-term obligations are right, then Washington is again selling the public a “cheap” war on the front end while quietly stacking enormous costs on the back end. Older readers have seen that movie before, and there is no reason to pretend this time is different without harder numbers.
