Iran Active Military
A potential military conflict between the United States and Iran would represent one of the most costly military engagements in American history. Based on analysis from the Congressional Budget Office, Brown University's Costs of War Project, and Department of Defense data, we project total costs ranging from $1.5 trillion to $2.8 trillion over a decade.
These estimates include direct military operations, equipment and weapons procurement, long-term veterans' healthcare and disability benefits, and the cumulative interest on borrowed funds used to finance the conflict. Iran's larger territory, stronger military capabilities, and regional proxy networks would make this conflict significantly more complex and costly than the Iraq War.
Explore our detailed breakdowns below to understand how these costs would accumulate and impact American taxpayers and the broader economy.
