The conflict has cost U.S. consumers $265 billion nationwide, Moody's estimates [2]. The findings place the economic burden of the conflict above earlier Moody's estimates. In June, Zandi had estimated the total cost at $100 billion, or about $750 per household [3], and in July, the tabulation was already higher than Moody's last estimate of the war's cost to households [4]. Zandi told CNN that many Americans had connected the war to their financial strain.
The national average price for a gallon of regular gasoline was $4.37 on Monday, up from just under $3 before the conflict began, according to the Daily Caller [5]. The gasoline increases began shortly after the U.S. bombing campaign started in late February [6]. By May, Brent crude had topped $126 a barrel, and the national average gasoline price had reached $4.30 per gallon, the highest since July 2022 [7].
Diesel prices surpassed $6 per gallon for the first time in September, up 60% from a year earlier [8]. At least 16 trucking, delivery and transportation companies entered bankruptcy proceedings between late August and Sept. 21, according to FreightWaves [9].
The rate increases have compounded the pressure on household budgets already strained by energy costs. The 10-year Treasury yield has surged past 5.2%, with indications it could climb higher [10]. The Federal Reserve's rate increases have contributed to a government debt-to-GDP ratio of 125%, with the U.S. having accumulated $155 trillion in debt by the end of 2022 [11].
A Congressional Budget Office (CBO) analysis found that the Iran war had already cost the Department of War $38 billion [12]. The war has also depleted U.S. weapons stockpiles, raising doubts about Washington's ability to protect the Persian Gulf [13]. The War Department's Lead Inspector General's office reported that 81 aircraft had been destroyed or damaged, for a total of $3.3 billion in costs, a fraction of the overall $43 billion sticker price for the war [14].
In June, the White House requested $87 billion in supplemental funding for stockpile replacements and troop deployments in the U.S. The bill will likely need Democratic votes to pass in the Senate [15].
The supplemental request comes as the total cost of the war continues to climb. A government report released in September found that the Iran war had already cost the Department of Defense $38 billion [12]. The CBO analysis and a separate report confirmed what outside analysts had claimed about the war's expense [12].
Zandi's estimates have tracked upward throughout the conflict. In May, Moody's calculated the cost at nearly $450 per household, which it said more than erased the boost of $384 per household from bigger tax returns under President Donald Trump's "big, beautiful bill" [16].
By September, the estimate had reached $1,760 per household. The latest figure of $2,000 represents a further increase as the war approaches its eighth month [17].
The cumulative burden on American households has steadily increased since the conflict began in late February. The war's economic effects have extended beyond direct household costs. Polling shows that three-quarters of U.S. citizens said the war on Iran has not been worth its human or financial cost [18]. Trump's overall approval rating stood at 32% in a Reuters/Ipsos survey of 1,277 U.S. adults, down from 35% a week earlier [18].
