Iran War Has Cost $45.1 Billion, Pentagon Tells Congress

The United States’ war with Iran has cost the country an estimated $45.1 billion, according to figures the Pentagon presented to Congress on Friday.

According to Ireporter Online, two sources familiar with the briefing said the Department of Defense informed lawmakers that direct war-related costs had reached $43.6 billion as of September 3, with an additional $1.5 billion spent on extra fuel.

However, the $45.1 billion figure does not represent a complete assessment of the financial impact of the conflict.

One of the sources said the estimate does not include the cost of repairing US military bases and other facilities damaged during the war. It also reportedly excludes detailed assessments of some indirect costs associated with military operations, despite requests from lawmakers for further information.

The latest Pentagon estimate is higher than the $38 billion projected by the Congressional Budget Office (CBO) as the cost of the war through August 1. It also represents an increase from the Pentagon’s previous estimate of $37.5 billion in July.

The CBO’s earlier projection similarly excluded expenses related to repairing damaged US facilities, with the majority of the estimated expenditure attributed to the cost of military munitions.

The budget office further estimated that the conflict could cost the United States between $2 billion and $3 billion every month beyond August 1, with spending expected to rise during periods of intensified fighting.

The CBO also warned that the continued conflict could contribute to higher inflation during the first quarter of 2027, potentially adding to economic pressures as concerns over the cost of living and broader economic conditions persist.
