Over 108 days, the war in Iran cost U.S. taxpayers an estimated $113.3 billion — counting from the first strike on February 28 through June 16, 2026. The clock has been stopped and the count preserved as a record.
This tracker ran in real time from the first strike, using the Pentagon's own briefing to Congress — $11.3 billion for the first six days — plus $1 billion/day ongoing. Senator Coons noted that figure is likely an undercount, and independent analyses suggest the true cost runs higher. The counter is now frozen; the full breakdown and methodology remain available.
