SAN DIEGO. Congress has been asked to approve $67 billion for the Iran war, yet nearly four months after that request, lawmakers still lack an adequate accounting of what the war has already cost. Published estimates run from $25 billion to roughly $100 billion. That gap is not a rounding error. It is a transparency failure, and taxpayers will eventually finance whatever number turns out to be true.
The numbers do not match
In April, Pentagon officials put the cost of the war at $25 billion. In July, Defense Secretary Pete Hegseth told the Senate Appropriations Committee it stood at $37.5 billion, a figure that included anticipated spending through the end of the budget year but left out the cost of rebuilding bases. The Congressional Budget Office then reported $38 billion through August, with costs rising by about $3 billion a month and borrowing costs not yet counted. The Pentagon later told Congress the total exceeded $42 billion, up $4.5 billion since July. Harvard’s Linda Bilmes, a budget expert, placed the figure near $100 billion in July.
Each number rests on different boundaries, which makes them impossible to compare. On the CBO’s pace, and by this author’s arithmetic, the total would reach about $44 billion by the end of October. Whether that is the right baseline is exactly what Congress cannot currently verify.
Financing matters too. The CBO’s figure excludes the interest on money the government borrows to pay for the war, which could add tens of billions of dollars. That arrives as the International Monetary Fund warns that global public debt is at its highest level since World War II and is on course to reach 100 percent of GDP by 2029. A war funded on credit, with no firm price attached, compounds a fiscal position that is already strained.
A request that bundles the war with other priorities
The White House formally requested $87.6 billion in June. Of that, $67.1 billion, or 77 percent, goes to the Pentagon. The remainder includes $11 billion for the Department of Agriculture, $3.4 billion for the State Department and $2 billion for Homeland Security. Senator Patty Murray, the lead Democrat on Senate Appropriations, objected that the request also seeks tens of billions for unrelated Pentagon priorities that belong in the annual appropriations process.
A September 17 letter from Democratic senators to Secretary Hegseth sharpened the point. It described the public $67 billion request as a seven-page document with vague descriptions, noted that the department still holds $34 billion in unspent funds from an earlier reconciliation package, and observed that a roughly $1.5 trillion fiscal 2027 request is also pending. The letter added that the department has briefed Congress seven times on the war and held eight press briefings, compared with more than 70 in the first month of the Iraq War alone.
Concern is not confined to one party. The House passed a $95 billion package in July, but it has stalled in the Senate, where Democrats have blocked it. Meanwhile, AP reported that some Republican senators voted for a war powers resolution, and Defense One noted that resolutions against the war passed both chambers, though mostly as symbolic gestures.
Costs outside the federal ledger
The burden also reaches households directly. Brown University’s Iran War Energy Cost Tracker estimated that Americans had paid more than $100 billion extra for gasoline and diesel by September 7, and reported on October 10 that the figure had passed $1,000 per household. Brown researchers caution that fuel prices are unlikely to fall quickly even if the fighting ended tomorrow. None of this appears in a Pentagon estimate, yet it is a substantial part of what the war costs the public.
A pragmatic path forward
Fiscal hawks and war skeptics can agree on three feasible steps. First, adopt one explicit definition of war cost and require the Pentagon to report it monthly, so figures from different offices can be compared. Second, separate the war request from unrelated priorities, so each receives its own vote and its own justification. Third, require a reconciliation of the $34 billion in unspent funds against any new money before Congress writes another check. During the Iraq and Afghanistan wars, lawmakers regularly received more detailed public requests than this one. That standard is evidently feasible.
In San Diego, home to a major concentration of Navy ships and personnel, the stake is concrete. Replenishing munitions and supporting service members is a legitimate national priority, and people here understand it better than most. Funding it responsibly, with a number the public can trust, serves the troops and the taxpayers alike.
