American drivers have paid an additional $8.4 billion in fuel costs since the Iran war started, according to an estimate from the Joint Economic Committee’s Democratic minority. That breaks down to about $240 million more per day just to fill up tanks. This financial hit has been building since February 28, when the U.S. and Israel initiated attacks on Iran. The lawmakers gathered their data from multiple sources. They looked at daily average gasoline prices tracked by AAA from February 28 through March 31, tank sizes of the top-selling gas vehicles from auto researcher Edmunds, and federal fuel consumption data from the Federal Highway Administration and the Energy Information Administration. According to CBS News, the national average gas price hit $4.11 per gallon on April 5: a cent higher than the day before, $0.86 higher than a month ago, and $0.85 more than a year ago. Gas prices topping $4 a gallon nationwide is a level the U.S. hasn’t consistently seen since 2022. Higher gas prices are quietly draining household budgets across America For individual drivers, the cost difference is significant. Filling up a Toyota RAV4 now costs about $58.26, a jump of $15.02 or a 35% increase compared to before the war. A Ford F-150 now costs $144.65 to fill, which is $37.29 more. Even Toyota Camry owners are spending $52.23 per fill-up, an extra $13.46 compared to pre-conflict prices. Despite the higher prices, credit card data shows that consumers are still spending, suggesting households are managing for now. However, the Conference Board Consumer Confidence Index, released on March 31, showed fewer Americans are planning big-ticket purchases over the next six months, which may indicate that elevated fuel costs are starting to affect budgets.

The Trump administration has said the spike is temporary and that prices will drop once the Iran war ends. Reports suggest that while Trump’s aides expect a swift end to the conflict, Trump himself has threatened to blow up power plants and bridges, resorting to bizarre profanity-laden social media tantrums.

Maggie Hassan, Democrat from New Hampshire and Ranking Member of the Joint Economic Committee, said “As gas prices soar, Americans are wincing at the pump as the total rolls higher, hoping that they soon hear that click,” and called the report “more proof of the ways in which President Trump continues to make it harder for families to get by.” A poll of 3,335 adults confirmed that rising gas prices are increasing concerns about the U.S. economy. Meanwhile, the human cost of the conflict is also growing, with hundreds of U.S. troops killed or injured as the war continues, and the Pentagon facing accusations of hiding the true toll. According to Fox Business, Texas and California have seen the sharpest increases. Texans have paid an extra $1.04 billion in fuel costs since February 28, while Californians have paid an additional $970 million. Florida added $684 million and North Carolina $361 million in extra gas spending. On the West Coast, prices are the highest nationally, with California at $5.92 per gallon and Washington at $5.38. Diesel has also surged, reaching $5.61 per gallon nationally, up about $1.45 over the past month, and in San Francisco, average diesel costs have surpassed $8 per gallon for the first time on record.
