The first six days of the U.S. military campaign against Iran cost more than 11.3 billion U.S. dollars, the Washington-based Center for Strategic and International Studies reported on Friday.
The sheer scale of Operation Epic Fury, the U.S. military campaign against Iran, is making it one of the most expensive U.S. military campaigns in decades, according to a report by the center.
The report estimates the war is costing over 890 million U.S. dollars per day. The first 100 hours of the attacks which began Feb 28 were estimated at 3.7 billion dollars.
The Pentagon has informed Congress that week one alone cost American taxpayers more than 11 billion dollars.
The biggest expenses come from the deployment of air and naval forces. Air operations are estimated at around 30 million dollars a day, while naval operations add about 15 million dollars daily. Ground operations account for over a million and a half dollars per day.
By comparison, Operation Midnight Hammer, which targeted Iran's nuclear facilities in June 2025, cost up to 2.26 billion dollars, according to media report. The strike lasted just about two and a half hours.

A large crowd of Iranians took to the streets of Tehran on Friday to mark the International Quds Day, an annual event expressing support for Palestinians and condemnation of Israeli actions.
The event, established by Iran in 1979, is observed on the final Friday of the fasting month of Ramadan. This year, it fell on March 13 and amid the ongoing U.S.-Israeli strikes against Iran.
Many participants felt the gathering this year carried a broader significance -- representing not only solidarity with the Palestinian cause, but also a reflection of their own national identity amid rising regional tensions.
"This year we're seeing a lot of people here. I have come a long way. What are the sins of these people being killed? We should be all present and support the oppressed," said Zeinab, a participant.
"I have come here to just say to the United States that there is nothing you can do to us. Our Supreme Leader is dead, but his son is here and we stand firmly behind them, even behind his son's son," said Tahere, a Tehran resident.
Many families, students and workers joined the marches, waving Iranian and Palestinian flags, as participants said the situation has strengthened unity at home.
"I have come here both for Palestine and for my country, and I have come here to say that we are Iranians and no one can invade our country," said Behrooz, a resident.
"This is my first time here and I want to say that although Imam Khamenei was killed, there are thousands of others like him and we will stand behind Mojtaba Khamenei forever," said Mehri, another resident.
