âU.S. regular gasoline retail prices, which averaged $3.36 per gallon in 2014, [will] average $2.43 per gallon in 2015 and $2.63 per gallon in 2016,â said the EIA. âThe average household is expected to spend $675 less for gasoline in 2015 compared with last year because of lower prices.â.
The average tax rate among all states, however, was 24.29 cents per gallon as of January 2015, according to the latest data from states and the Federal Highway Administration. With the average vehicle using 524 gallons of gasoline, this means the average cost of state gasoline taxes was $127.26 per vehicle. The average household with 1.75 vehicles thus pays $222.70 in state gasoline taxes or $4.27 per week.
