The conflict in Ukraine has caused gas prices to soar in the United States.

Prices can vary greatly from one state to the next, due to taxes, government policies and close proximity of oil refineries. It costs an average of $4.33 to fill up a gallon with regular, unleaded fuel in the U.S., while it is more expensive in nine states than that, according To gas prices provided by the American Automobile Association.

This is a breakdown of how much one gallon of gasoline costs in every state, as per Monday’s data from AAA.

California is the state where gas prices are highest. An average gallon will cost $5.74. This is almost 2 more than the gas you would pay in Kansas which, despite being the least expensive state for gasoline.

The following are some of the priciest states for buying gas.

These states are where the gas prices are lowest:

Average driver’s driving experience 39 miles per dayTheir vehicle averages 24.2 miles per gallon of gasAccording to data from the government, it is. That works out to $9.26 in gas per day in California and $6.15 in Kansas — a difference of roughly $100 per month.

In 2021, when gas prices averaged $2.86 per gallon nationwide, the average driver was paying only $4.61 per day. This represents an average increase in monthly gasoline budgets of approximately $80 to $125 over the past year. 

These prices do not necessarily reflect real gas consumption as drivers drive differently. For example, drivers in Wyoming have relatively cheap gas but they drive 24,069 miles per year on average — nearly twice that of California, according to Federal Highway Administration data.
