The war in Iran has cost the United States about $25 billion so far, according to a Pentagon official, as the conflict reaches the 60-day mark and continues to strain American military resources.

The estimate comes amid mounting questions over the total cost of the campaign and the scale of the U.S. military’s ongoing involvement. Earlier Pentagon briefings had already put the cost of the first six days of the war at more than $11.3 billion, before additional expenses for deployments, munitions and sustained operations were fully counted.

The latest figure of $25 billion reflects a conflict that has rapidly become one of the most expensive U.S. military operations in recent years. Reports have said the White House is seeking a major defense budget increase partly because of the war, while lawmakers have raised concerns over how quickly costs are rising.

The spending estimate also comes as the Trump administration continues to maintain pressure on Iran through military posture and maritime restrictions. U.S. officials have said naval and air assets remain active in the region, and the broader campaign has been linked to efforts to choke off Iranian oil revenues.

Analysts have noted that the final bill will likely be higher once replacement weapons, logistics and other indirect costs are included. A March cost estimate from Pentagon-related reporting suggested the early days of the war alone had already exceeded $11.3 billion, a figure that underscored how quickly the campaign was consuming resources.

With the conflict now at the 60-day point, the Pentagon’s latest estimate adds fresh weight to debate over the military and financial burden of the war. The scale of spending has also become a political issue in Washington as the administration asks Congress for larger defense allocations.
