US Expenses in Iran Conflict Reach $38 Billion, Congressional Budget Office Report Reveals

The Iran war has cost the US taxpayer at least $38 billion as of August 1, with ongoing expenses projected at approximately $3 billion per month if the conflict persists, according to a recent report. Released on Tuesday by the Congressional Budget Office, the report details that the $38 billion total covers expenses for replacing used munitions, battle-lost equipment, increased flying hours, operational costs, and higher fuel prices.

This total aligns closely with the figures presented to Congress in July by Defence Secretary Pete Hegseth. The CBO noted that depending on the intensity of the violence, Pentagon expenditures could remain around $3 billion monthly. "Monthly costs could be higher still if the violence escalated further," the report stated.

The CBO clarified that its estimates exclude expenses absorbed by other federal agencies, such as the impact of rising fuel costs, as well as expenditures already integrated into the federal budget. A significant driver of the conflict's cost has been the heavy use of missile defence interceptors, which the report warns will leave the US facing reduced stockpiles "for several years". The agency cautioned that this shortage could prove particularly concerning in the event of a conflict with an adversary possessing large quantities of ballistic and cruise missiles, specifically pointing to weapons held by China.

Last week's Pentagon inspector general's report similarly highlighted "strategic inventory shortfalls" alongside industrial bottlenecks affecting resupply efforts. While these shortages have received widespread coverage in recent months, President Donald Trump's administration has consistently disputed the claims. President Donald Trump maintained in a social media post last week that the US is "producing more exquisite and elite weapons than at any time in our history". In response to ongoing demands, the Pentagon has finalized tens of billions of dollars in production agreements with defence contractors over the past few weeks, including deals last month with Raytheon, Northrop Grumman and Lockheed Martin aimed at accelerating the manufacturing of missiles and missile components.
