The Trump administration’s expanding military campaign against Iran is costing American taxpayers an estimated $1 billion per day, according to reporting and policy analyses, drawing criticism from lawmakers, candidates, and analysts who say the enormous war spending is happening while hospitals face closure and millions of Americans lose access to healthcare.
The figure emerged after Atlantic journalist Nancy Youssef reported that a congressional official provided a preliminary estimate from the Pentagon indicating that a “preliminary Pentagon cost estimate of the war in Iran is $1 billion a day.”
The estimate quickly became a focal point for critics who say the cost of the conflict stands in sharp contrast to cuts to domestic healthcare and social programs.
Responding to the report, Democratic Senate candidate Graham Platner of Maine asked what he described as a basic question about federal priorities.
“We can’t afford to keep our hospitals open, but we can afford a billion dollars a day to bomb Iran?” Platner wrote in a social media post.
His comments come as hundreds of hospitals across the United States, particularly in rural communities, are described as being on the brink of bankruptcy or closure. The financial pressure on healthcare systems intensified after President Donald Trump signed a spending and tax bill last year that provided billions of dollars in tax breaks to corporations and wealthy individuals while cutting healthcare programs including Medicaid.
At the same time, Congress declined to use its authority to limit the war. Sen. Susan Collins of Maine joined nearly every member of the Republican caucus in voting down a War Powers Resolution that would have compelled Trump to halt military operations against Iran.
Sen. Brian Schatz of Hawaii pointed to the cost of the war as evidence that federal spending priorities have shifted away from domestic needs.
“This war is costing a billion dollars a day,” Schatz said. “In one fucking month we will spend more over there than we needed to save healthcare for more than 2 million Americans. They literally are taking away your food and your healthcare for this regime change war of choice.”
Estimates suggest the financial cost of the conflict escalated rapidly in the first days of military operations.
An analysis by Allison McManus of the Center for American Progress examined early details of Operation Epic Fury. In a March 2 press conference, Chairman of the Joint Chiefs of Staff Gen. Dan Caine described the deployment of more than 100 aircraft, the use of Tomahawk missiles, and attacks on more than 1,000 targets in the first day of operations.
Using cost comparisons from Brown University’s Costs of War project, McManus estimated that the operations described by Caine alone would likely cost more than $4 billion.
Additional expenses increased the early cost estimates. Elaine McCusker, a former Pentagon official during the first Trump administration, estimated that repositioning U.S. forces across the Middle East cost approximately $630 million even before hostilities began.
A separate incident also added to the financial toll. On March 2, Kuwaiti forces accidentally shot down three U.S. F-15 fighter jets in a friendly fire incident. With each aircraft costing as much as $117 million, the destroyed aircraft represented an estimated loss of $351 million.
Taken together, McManus concluded that the early costs of Operation Epic Fury exceeded $5 billion within the first days of the campaign.
A separate analysis from the Center for Strategic and International Studies reached a similar conclusion about the financial scale of the war’s opening phase. The organization estimated that the first 100 hours of the Iran conflict cost $3.7 billion, which equals approximately $891.4 million per day.
While the military spending climbs, analysts say those same funds could support major domestic programs.
An analysis published by the National Priorities Project found that the estimated $1 billion daily cost of the war could cover the daily costs of federal nutrition assistance for more than 40 million Americans. The same amount could also cover the daily Medicaid costs for roughly 16 million people expected to lose health coverage under the Republican budget package Trump signed into law last year.
Researchers Alliyah Lusuegro and Lindsay Koshgarian said the spending tradeoff is becoming increasingly clear.
“That money could cover the things we need here at home,” they wrote.
“The tradeoff is clear: the Trump administration backed by several members of Congress is cutting healthcare and food assistance for millions of families while spending $1 billion a day on this emerging war.”
They added that the scale of the spending highlights a broader question about national priorities.
“The question isn’t whether the money exists—it’s what we choose to spend it on.”
Analysts have also pointed to the opportunity cost of individual weapons used in the conflict. According to the Center for American Progress analysis, a single Tomahawk missile costs approximately $2.2 million. That amount could cover healthcare through Medicaid for 775 children for a year or provide meals through the National School Lunch Program for more than 3,600 children.
The report also found that the more than $5 billion already spent in the early phase of the war could cover Supplemental Nutrition Assistance Program benefits for more than 2 million Americans for a full year.
Independent journalist Zaid Jilani summarized the criticism surrounding the administration’s spending priorities.
“Trump is spending a billion dollars a day killing people abroad while cutting Medicaid and health care for Americans.”
Meanwhile, the Pentagon is expected to request additional funds to sustain the conflict. Reporting cited in the source material indicates the Defense Department plans to ask Congress for at least $50 billion in supplemental funding for the war.
The request would come despite polling that shows a large majority of Americans oppose the conflict.
Rep. Brendan Boyle of Pennsylvania recently asked the Congressional Budget Office to conduct a comprehensive analysis of the war’s financial impact, including scenarios in which the conflict extends beyond five weeks or expands into a ground invasion.
“Taxpayers deserve a nonpartisan estimate of the financial and economic impact of President Trump’s reckless war in Iran that has already led to the tragic deaths of American servicemembers,” Boyle said. “American families don’t want billions of dollars wasted on an unnecessary war—they want lower costs and affordable healthcare.”
Policy experts warn that the final cost of the war could take years to fully calculate.
“The cost of the war in Iraq ended up being almost $3 trillion,” said Lindsay Koshgarian. “This could be astronomical, easily.”
