The US war with Iran has come to a halt, at least for now, with President Donald Trump claiming that Americans have won. However, an objective analysis of the war’s impact on the US reveals a more nuanced story. The conflict has cost the Department of Defense around $40 billion, according to preliminary numbers from the Center for Strategic and International Studies.

War Costs and Economic Impact

The figure includes the cost of munitions, destroyed equipment, and damage to bases, but does not incorporate operational costs that were already factored into the department’s fiscal year 2026 budget. The Pentagon has submitted a request for $80 billion in supplemental funding, with less than $20 billion related to immediate needs from the Iran war.

The war has also driven up gas prices, with the average US price rising from less than $3 per gallon to over $4 during the conflict. American households have spent more than $253 extra on gas due to the war, according to an energy cost tracker from Brown University.

The conflict has also affected farmers and shippers, with diesel prices rising from around $3.80 before the war to over $5 as of June 15. The increased price of diesel has resulted in Americans spending nearly $27.1 billion extra.

Oil Reserves and Production

The nation’s emergency reserve of oil has been depleted, with the reserve now at its lowest level since 1983. The world lost 1.15 billion barrels of oil supply during the war, according to Kpler. As a result, the US has been taking crude from other sources, including Venezuela and Brazil, and has de-sanctioned hundreds of millions of barrels of Russian and Iranian oil.
