Since the war started, Americans have spent an additional $33 billion on gasoline, according to a Brown University estimate<\/a>. Increased gas prices have resulted in higher monthly expenses for individuals \u2014 anywhere from less than $20 to more than $300 for a driver who fills up twice a month, according to an NBC News analysis of AAA\u2019s average national gas price data<\/a>.<\/p>\n Just how much has the spike in gas prices bitten into your budget? Use our calculator to estimate your additional expenses at the pump since the start of the war in Iran. The calculator updates with the latest data daily.<\/p>\n The cost model used in the calculator takes a sample of the average daily gas price in the U.S. since the start of the war, simulating how gas prices vary depending on which day you fuel up. The results you get will fall in a range of average costs and change slightly as you use the tool. <\/p>\n Since Feb. 28, when the U.S. first struck Iran, average gas prices<\/a> nationally have risen 34%. A recent peace deal announcement<\/a> and subsequent memorandum of understanding<\/a> have indicated the war could finally be close to the finish line. <\/p>\n Gas prices hit the 10th-highest weekly rate in the past 10 years the week of May 11, at an average of $4.63 per gallon nationally, according to data from the U.S. Energy Information Administration<\/a>. The average gas price last topped $4 in 2022<\/a>, after Russia invaded Ukraine. <\/p>\n Faced with higher prices, some Americans are driving less, or at least filling up less often. An analysis by the location analytics company <\/a>Placer.ai<\/a> found gas station visits across the U.S. were down 5% in May compared with May 2025. <\/p>\n Consumers\u2019 spending habits are also changing; April data from the Federal Reserve Bank of New York<\/a> found consumers expect to spend more on transportation and utilities over the next 12 months and less on vacations, homes and electronics. <\/p>\n
