At $2.838 a gallon, Seattle area consumers paid 12.6 percent more than the $2.521 national average in December 2017.

The 10.9 cents per kWh Seattle households paid for electricity in December 2017 was 19.9 percent less than the nationwide average of 13.6 cents per kWh. Last December, electricity costs were 21.8 percent lower in Seattle compared to the nation. In each of the past five years during the month of December, prices paid by Seattle area consumers for electricity were less than the U.S. average by at least 19.9 percent. (See chart 2.)
Prices paid by Seattle area consumers for utility (piped) gas, commonly referred to as natural gas, were $1.078 per therm, or 3.5 percent more compared to the national average in December 2017 ($1.042 per therm). A year earlier, area consumers paid 15.4 percent more per therm for natural gas compared to the nation.

Average prices are estimated from Consumer Price Index (CPI) data for selected commodity series to support the research and analytic needs of CPI data users. Average prices for electricity, utility (piped) gas, and gasoline are published monthly for the U.S. city average, the 4 regions, the 3 population size classes, 10 region/size-class cross-classifications, and the 14 largest local index areas. For electricity, average prices per kilowatt-hour (kWh) are published. For utility (piped) gas, average prices per therm, are published. For gasoline, the average price per gallon is published. Average prices for commonly available grades of gasoline are published as well as the average price across all grades.
All eligible prices are converted to a price per normalized quantity. These prices are then used to estimate a price for a defined fixed quantity. The average price per kilowatt-hour represents the total bill divided by the kilowatt-hour usage. The total bill is the sum of all items applicable to all consumers appearing on an electricity bill including, but not limited to, variable rates per kWh, fixed costs, taxes, surcharges, and credits. This calculation also applies to the average price per therm for utility (piped) gas.
