The administration of Donald Trump estimates that the United States has spent about $11.3 billion during the first six days of its military campaign against Iran, according to a report cited by officials and lawmakers in Washington.
Officials told members of Congress that the cost reflects extensive use of advanced munitions, airstrikes, and naval operations carried out since the conflict began in late February with coordinated U.S. and Israeli attacks on Iranian military infrastructure.
The Pentagon had already reported that $5.6 billion worth of munitions were used in the first two days of the operation alone, highlighting the high financial intensity of the war.
U.S. officials have warned lawmakers that the overall cost could rise significantly, with estimates suggesting that an additional $50 billion may be required if military operations continue in the coming weeks.
The growing financial burden has sparked debate in Washington over war funding and the long-term economic impact, particularly as global energy markets remain volatile and oil prices surge amid escalating tensions in the Middle East.
