US Iran war costs exceed $47 billion in Pentagon estimate obtained by Reuters
The reported military cost has risen more than 25% from a July estimate, while repairs to damaged US bases may not be fully accounted for.
US military costs for the war in Iran have exceeded $47 billion, according to Pentagon data obtained by Reuters and reported on October 27. The figure is more than 25% above a July estimate, showing how the cost of the conflict has risen even before the full expense of repairing damaged US bases is clear.
Reuters said the Pentagon had not made the latest estimate public and had not immediately responded to a request for comment. Defense Secretary Pete Hegseth put the war's cost at $37.5 billion in July. The new estimate is tied to operational costs, including flight operations and cyber support.
What is included in the Pentagon estimate
More than $29 billion of the latest estimate is the projected cost of replacing munitions used in the conflict, Reuters reported. More than $6 billion would be needed to replace military equipment and cover platform losses, a category that includes aircraft and drones lost during the war. Those replacement figures form part of the reported military cost; they are not a separate bill to add to the $47 billion total.
The military's estimates did not clearly account for the expected expense of repairing US bases damaged by Iranian missile and drone attacks, according to Reuters. That leaves the scale of those repair costs unresolved within the reported figure.
Fuel costs are a separate burden
The Centre for Research on Energy and Clean Air estimates that the disruption to oil supplies through the Strait of Hormuz has added $468 billion to the world's diesel and gasoline bill since US and Israeli attacks on Iran began at the end of February. It puts the additional US fuel bill at $160 billion, or $471 per person, the highest per-person cost of any country in its analysis. These are estimates of higher fuel spending, separate from the Pentagon's military spending figure.
CREA attributes the high US per-person cost to heavy fuel consumption and reliance on private vehicles. It says households, truckers and farmers are particularly exposed to fuel price shocks, even though the United States is the world's largest oil producer. Its calculations use fuel prices and consumption estimates, with US diesel and gasoline volumes scaled using a monthly index from Energy Information Administration data.
Why the costs matter now
The war's effect on energy prices has become a political issue ahead of the November 3 congressional election, Reuters reported. President Donald Trump's Republican Party holds narrow majorities in both chambers. Reuters also reported that Trump has imposed a naval blockade on Iran and raised the possibility of restarting combat operations after the election; US officials said the Pentagon was preparing for heavier fighting if ordered to resume it.
