How Much Is the Iran War Costing the US? Pentagon Estimates $11.3 Billion in Just 6 Days
The United States has spent more than $11.3 billion (around £8.45 billion) on the Iran war in just the first six days of combat, Pentagon officials told lawmakers in a closed‑door briefing this week, according to congressional sources familiar with the discussions. This early estimate reflects only part of the cost of the conflict, which began with coordinated US and Israeli airstrikes on February 28.Officials told the Senate Appropriations Subcommittee on Defence that the $11.3 billion figure does not include all operational expenses, such as the pre‑deployment of forces and the logistics of sustaining military operations across the Middle East. Lawmakers expect the total cost to rise substantially as further calculations are completed.Munitions and Military Hardware Drive CostsA significant portion of the early expenditure has been on munitions and advanced weapons systems. As first reported by The New York Times, Pentagon briefings indicated that about $5.6 billion worth of munitions (roughly £4.19 billion) were used in the first two days of the campaign, far exceeding typical usage rates in recent conflicts and underscoring the intensity of the opening strikes.These weapons include precision‑guided bombs and long‑range missiles, some of which cost hundreds of thousands of dollars each. The sheer volume of ordnance fired has driven up both immediate spending and the need to replenish stockpiles, a process that could add further expense to the overall campaign budget.Operational Intensity and Wider Military EngagementThe financial burden reflects the wider scale of Operation Epic Fury, the codename for the US‑led military engagement against Iranian targets and related operations in the region. In addition to airstrikes deep inside Iranian territory, the conflict has involved missile defence systems, naval deployments in the Persian Gulf, and sustained aerial and ground support missions.In a report by CTGN, a defence think tank recently estimated that the war was costing US taxpayers about $890 million per day (£665 million) in its early stages, based on munitions, combat operations and other direct costs. Much of this spending is currently unbudgeted, meaning additional funds are likely to be sought from Congress through supplemental appropriations requests.Human Cost and Military Casualties
While the monetary cost has drawn growing attention, the human toll of the conflict is also rising. The Pentagon has reported that as many as 150 US service members have been wounded in the course of fighting, with eight classified as severely injured. The majority of these wounds are described as minor, and many soldiers have already returned to duty.In addition to injuries among US forces, multiple fatalities have been reported. The Pentagon recently confirmed that at least seven US service members have died in action, underscoring the persistent hazards faced by troops in the contested theatre.Broader Regional ImpactThe conflict has rapidly expanded beyond its opening days, with Iranian missile and drone attacks targeting allied forces and regional infrastructure. These engagements have disrupted shipping through the Strait of Hormuz and rattled global energy markets, fuelling concerns about long‑term economic effects beyond the direct military costs.Regional combat has also inflicted heavy casualties on non‑combatants. Independent assessments suggest thousands of Iranian and Lebanese civilians have been killed as the war has widened, complicating efforts to quantify the full cost of the conflict in both financial and human terms.Congressional Funding and Future CostsWith the cost of the early phase of the war already exceeding $11.3 billion, lawmakers are preparing for debates over how much additional funding to allocate to sustain military operations. Some congressional aides have indicated that requests for supplemental appropriations could exceed $50 billion (£37.4 billion) as planners account for future expenditures and replenishment of military stocks.The Pentagon has not released a comprehensive public estimate of the total expected cost, and officials have cautioned that final figures will not be available until the conflict's duration and intensity are clearer.
