U.S. war on Iran has cost $25 billion so far, says Pentagon official | 29 April 2026 | The United States’ war on Iran has ​cost $25 billion so far, a senior Pentagon official said on Wednesday, providing the first official estimate of the military’s ‌price tag for the conflict. Jules Hurst, who is performing the duties of the ​comptroller, told lawmakers on the House Armed Services Committee that most of that money was for munitions. But it is unclear how the Pentagon arrived at the $25 billion amount given that a source had told Reuters last month that President Donald Trump’s administration estimated that the first six days of the war had cost the United States at ​least $11.3 billion.
