Iran war cost: Average U.S. household paying $450 more on gas and energy

Americans have spent nearly $450 extra per household on rising energy costs during the Iran war, according to an analysis shared exclusively with CNBC's Steve Liesman.

The average household has shelled out $447.19 for additional fuel-related expenses since the conflict began on Feb. 28, data from Moody's Analytics found. That's cumulatively cost American consumers nearly $60 billion as gas prices and airline fares have surged.

Moody's data puts a dollar amount on a portion of the economic pain Americans are feeling as the war reaches its three-month mark. Higher energy costs can force consumers to raid their savings and lean more on debt to cover expenses.

“Unless the war ends soon, financially pressed consumers will have no option but to turn more cautious in their spending, threatening the already soft economy,” said Mark Zandi, Moody's chief economist.
