The U.S.-Iran War: By the Numbers
(Time) -snip- Defense Secretary Pete Hegseth has been relatively tight-lipped about how much funding was being absorbed by the conflict, but Jay Hurst, the Pentagon comptroller, testified in May that Operation Epic Fury had already cost American taxpayers some $29 billion.
Several outlets have reported that the true cost of the war to the U.S. could be closer to $50 billion if it takes into account the bill for repairing extensive damage to military bases and replacing damaged or lost drones and missiles.
There will be a lasting impact on economic growth as the country faces a long process resolving outstanding costs, according to analysts. Goldman Sachs said in March that the war had "lowered our 2026 U.S. growth forecast and raised our 2026 U.S. inflation forecast to reflect higher oil prices"—a direct result of Iran closing the Strait of Hormuz.
