Pentagon Estimates Iran War Costs at $37.5 Billion, Seeks Additional Funding

Defense Secretary Pete Hegseth stated at a Senate Appropriations Committee hearing on July 21, 2026, that the cost of the ongoing war with Iran has reached $37.5 billion. This figure is an increase from the previous estimate of approximately $30 billion provided earlier in the month. The Defense Department is requesting $67 billion in supplemental funding to continue military operations in the coming months. NBC News reported that the internal overall cost of the war is estimated to be between $80 billion and $100 billion, which includes expenses for repairing military bases and replacing destroyed aircraft. Hegseth's estimate encompasses payroll, operation, maintenance, and other anticipated costs through the end of the budget year. The hearing occurred amid escalating tensions following a ceasefire breakdown and recent fatalities among U.S. service members. Hegseth faced criticism from Senate Democrats regarding the lack of progress in the conflict, with Senator Gary Peters questioning the administration's strategy. Hegseth defended the efforts, stating that the situation has significantly weakened Iranian capabilities.
