$100 Billion: How Much a Trump-Era Iran War Could Cost the United States

An estimate suggests a possible Trump-era Iran conflict could cost the United States roughly $100 billion. The figure accounts for direct military spending as well as secondary expenses tied to operations, logistics, and sustained engagement. The projection also factors in broader economic pressures that could follow escalation, including energy-market disruption and defense-related spending growth. The outlook underscores how quickly costs can compound when a regional conflict expands, even before considering political and rebuilding costs afterward.
