What is the breakdown of the price of a gallon of gas, and why prices vary between cities?
Where does all the money? Local taxes? Shipping? Service Station? Earnings?
Major components of gas prices: Oil Price: $ 67/barrel. 1 barrel = 42 gallons of oil to make about 20 gallons of gasoline, but the remaining 22 gallons of product is also sold. It is difficult to bring exactly how much of that $ 67 is the cost of gas, but is about $ 2.25/gallon today. Much of this is going to find oil, drilling, transportation to refineries, storage, … of Refinery costs and benefits benefits: The benefits here are particularly high because it has not been a new refinery built in the U.S. since the 70s. In some part around $ 0.50/gallon. Taxes: Federal: $ 0.184/gallon. State: Varies from $ 0.07 to $ 0.32/gallon Transportation: Varies based on the place, I think it has to be 0.20/gallon ($ subject is almost free passage per gallon, truck transport is the main cost). desired markup to cover the costs and benefits.
