U.S. Secretary of Defense Pete Hegseth said to senators on Tuesday that the war with Iran has cost an estimated $37.5 billion [1].

The disclosure comes as the Pentagon seeks additional funding to maintain military operations amid heightened tensions with the Iranian government. This figure provides the first concrete estimate of the conflict's financial burden as lawmakers debate the U.S. budget.

Hegseth provided the figure during a Senate Appropriations Committee hearing in Washington, D.C. He said the need for continued funding to support the current strategic objectives of the administration is necessary.

"The war against Iran has cost $37.5 billion so far," Hegseth said [1].

He said that this updated figure is higher than previous internal assessments provided by the Department of Defense [3]. The secretary said the current financial state of the conflict is a significant price tag that requires ongoing congressional support to manage [2].

While some automated summaries of the proceedings initially cited the cost in the tens of millions of dollars, official testimony and primary reporting from the hearing confirm the multi-billion dollar figure [1, 2, 3].

Senators questioned Hegseth on the sustainability of the spending and the specific allocation of resources. The hearing focused on whether the requested funds would accelerate a resolution or further prolong the engagement. Hegseth said the funding is essential to ensure U.S. forces remain equipped, and capable of responding to threats in the region [1].

The disclosure of a $37.5 billion cost marks a pivot toward fiscal transparency regarding the Iran conflict. By presenting a specific, elevated figure to the Senate Appropriations Committee, the Department of Defense is attempting to anchor future funding requests in a quantified reality, potentially signaling that the conflict is more resource-intensive than initially projected.
