Pentagon estimates cost of Iran war

May 16, 2026

The Iran war is costing the US far more than the Pentagon admits, and Americans are footing the bill while Israel pays nothing.

  • The Pentagon now says the war cost $29 billion, up from $25 billion a few weeks ago, but outside reporting suggests it is closer to $1 billion a day.
  • A University of Michigan economist estimates the real cost will run into hundreds of billions or even trillions when oil prices, lost jobs, and stock losses are counted.
  • Oil futures for 2026, 2027, and 2028 are still well above pre-war levels, and uncertainty is making businesses hold off on hiring and investment.
  • The Fed was expected to cut interest rates but may now have to raise them, which could cost the economy another $200 billion.
  • The Iraq war was first sold as a $1.2 billion conflict and ended up costing over $2 trillion, so the early Iran numbers are likely a massive undercount.

Outlook: Costs will keep climbing as oil stays high, the Fed holds or raises rates, and the war drags on with no sign Israel will help pay.
