Expert Estimates US Iran War Costs at $72 Billion

Stephen Semler, a senior fellow at the Center for International Policy, calculates that the war is consuming an average of $1.2 billion daily. This estimate accounts for munitions, troop deployments, and military assets, yet Semler notes it remains a conservative figure. It excludes long-term obligations such as veterans' care, interest on national debt, and broader economic fallout.

Semler argues the Pentagon’s official accounting is fundamentally flawed, citing a failure to properly track munition expenditures and the exclusion of State Department-funded military aid to Israel. His assessment aligns with recent reports from unnamed administration officials who suggested to CBS News that costs have already eclipsed $50 billion. Much of that discrepancy stems from the rapid attrition of high-value equipment, including 24 MQ-9 Reaper drones, each valued at approximately $30 million.

As the administration faces mounting scrutiny over the war's financial and human toll, President Trump continues to signal a potential escalation. Following threats of intensified bombing campaigns, any expansion of the conflict threatens to push these expenditures significantly higher, further straining a ledger already impacted by the disruption of global energy markets.
