The US war against Iran has resulted in significant costs for the Department of Defense, exceeding $38 billion through August 1. Ongoing expenses are expected to range from $3 billion per month or more, depending on the conflict's intensity.

The nonpartisan Congressional Budget Office released this assessment, which also notes that the war will contribute to inflation. This is largely due to reduced oil and natural gas shipments and disruptions to shipping.

Further details on the estimate and its implications are available from the Congressional Budget Office's assessment, which was released in response to a request from a House Budget committee member.
